Fork U with Dr. Terry Simpson

Salt: From the Roman Legion to Your Electrolyte Packet You've probably heard that Roman soldiers were paid in salt—and that this is where we get the word salary. It's a great story. It's also almost certainly not true. The Romans had money. We find Roman coins throughout the former empire, including around military forts such as those along Hadrian's Wall, and we have evidence that Roman soldiers were paid in money. What we do have is an ancient linguistic connection between the Latin sal, meaning salt, and salarium, which eventually gives us salary. Somewhere along the way, that became the much better story that a legionary went to the quartermaster and collected his wages at the imperial salt lick. But the fact that the story sounds believable tells us something important: salt really was extraordinarily valuable. Long before Rome, humans sought salt just as other animals do. Animals travel to mineral licks, and humans learned to exploit saline springs, coastal deposits, and eventually salt mines. Nobody needed to measure a serum sodium to discover salt. We had two very good reasons to want it: salt tastes good, and salt preserves food. That second property changed civilization. Meat and fish could be salted and dried. Vegetables could be fermented. Milk could be transformed into cheese, concentrating its nutrition and allowing it to last far longer than fresh milk. Salt helped food survive winter, travel aboard ships, and provision armies. The Egyptians even used natron—a mixture of sodium salts rather than ordinary table salt—to dry and preserve their dead. Hence the mummy. Or occasionally, presumably, the daddy. Once everyone wanted salt, governments discovered the next obvious thing to do: tax it. Salt became a source of state revenue in ancient China, traveled along trade routes in Rome, was burdened by the French gabelle, and eventually became the focus of Gandhi's famous Salt March against British rule in India. Then something changed. We got very good at producing salt, and we invented refrigeration. One of the principal reasons humans had consumed large quantities of salt—preserving food—became much less important. Unfortunately, we didn't stop liking the taste. Modern food manufacturers discovered that salt was cheap, improved flavor and texture, and could be added to almost everything. Today, the problem is rarely finding enough sodium. It's avoiding too much of it. There was, however, one particularly clever moment when public health took advantage of our universal salt habit. Iodine deficiency once produced enormous numbers of goiters and, more importantly, could impair fetal and childhood brain development. In 1924, iodized salt appeared on grocery shelves in Michigan as part of the American effort to combat endemic iodine deficiency. The idea was beautifully simple: everybody eats salt, so put iodine in the salt. Salt iodization became an extraordinarily effective way to prevent iodine-deficiency disorders, and it remains recommended by the World Health Organization. Which makes today's fascination with expensive “mineral” salts particularly amusing. Celtic sea salt, Himalayan pink salt, and other specialty salts contain magnesium, calcium, and other minerals—but in trace amounts. If you like their taste or texture, wonderful. I have fancy salts in my kitchen too. That's cuisine, not cardiology. If you want magnesium, eat some nuts. And then buy Morton's. We have performed a similar trick with hydration. There are people who genuinely need extra sodium: athletes exercising for hours, people working in extreme heat, and people experiencing substantial fluid losses. The development of sports drinks was a reasonable response to athletes losing both water and electrolytes during prolonged exercise. Somehow, that became the idea that everyone needs mango-flavored electrolytes simply because they own a water bottle. Most of us don't. Sodium is essential, but essential doesn't mean unlimited. The WHO currently recommends adults consume less than 2,000 mg of sodium per day—about 5 grams of salt—and notes that average global sodium intake is more than twice that amount. Most dietary sodium isn't necessarily coming from the salt shaker. Processed meats, breads, sauces, prepared foods, restaurant meals, cheese, and other frequently consumed foods can contribute substantial amounts. That doesn't mean your food needs to be bland. Cook vegetables. Eat legumes. Have fish. Use olive oil, herbs, spices, lemon, and vinegar—and use enough salt to make good food taste good. Just don't confuse seasoning your dinner with adding unnecessary sodium to an already sodium-rich diet. Salt helped build civilizations. It preserved food, provisioned armies, generated taxes, helped make cheese possible, and eventually became a vehicle for preventing iodine deficiency. We spent thousands of years figuring out how to get enough of it. Now we've become so good at it that we're paying extra to put more of it in our water. Listen to this episode of FORK U for the story of salt, and head over to drsimpson.com for the deeper dive into sodium, blood pressure, vascular health, salt sensitivity, gastric cancer, electrolytes, and what the science actually says about how much salt we should be eating.

How a tiny seed changed the way we work, think, meet, and start the dayBread gave civilization calories. Beans gave it protein. Olive oil gave it light. Coffee gave civilization somewhere to meet—and a reason to stay awake.Coffee came late to Western civilization. The Greeks didn't have it. The Romans didn't have it. Even Galileo had to stay awake at night looking through his telescope without the help of an espresso machine. Historians no longer like the old idea of the “Dark Ages,” and for good reason. But I have my own definition: the Dark Ages were simply the time before Western civilization discovered coffee.Coffee Started as a FruitFirst, coffee isn't really a bean. What we call the coffee bean is the seed of a fruit, often called a coffee cherry. Coffee plants originated in Africa, especially Ethiopia, where we get the wonderful legend of a goat herder named Kaldi. He supposedly noticed that his goats became unusually energetic after eating the red fruit from a coffee tree. The goats danced, Kaldi tried the fruit, and eventually the local monks discovered it helped them stay awake for evening prayers.It's a great story, although there isn't much evidence that Kaldi actually existed. The history becomes more reliable by the 1400s, when we know people were drinking coffee in Yemen. From there, coffee traveled along trade routes through the Middle East and into the Ottoman Empire. Somewhere along the way, something important happened: coffee stopped being simply a drink and became a reason for people to gather.Coffeehouses Woke People UpBy the 1500s, coffeehouses were appearing in the Ottoman world. People came to drink coffee, but they stayed to talk about business, politics, religion, news, and probably their neighbors. Coffee eventually moved west, and by the 1600s, coffeehouses were spreading across Europe. London's first coffeehouse is generally dated to 1652.Some of these coffeehouses became known as “penny universities.” For the price of a cup of coffee, you could sit, listen, argue, and perhaps learn something. Coffee did not cause the Enlightenment, but it certainly provided a convenient place for people to discuss it. Unlike the tavern, the main drug being served made people more alert instead of less.The Swedes Took Coffee SeriouslyThen there were the Swedes. After losing to Russia in 1709, King Charles XII of Sweden spent several years in Ottoman territory. While there, he and his companions developed quite an affection for coffee. When the Swedes eventually returned home, that affection came with them, and coffee became deeply rooted in Swedish culture.Today, the Swedes have fika, which is much more than a coffee break. You stop what you are doing, sit down, usually have something to eat, and most importantly, talk to another person. In other words, coffee provides an excuse to stop working long enough to remember that there are other human beings around you.That sounds remarkably familiar to me.Coffee in Rainy AlaskaI grew up in Ketchikan, Alaska, one of the wettest cities in America. Some years, the rainfall can approach 200 inches, and this isn't always the lovely rain that gently falls outside while you read a book beside the fireplace. In Ketchikan, the rain sometimes blows sideways.Many women of my mother's generation had moved to Alaska because their husbands brought them there. Their families might be thousands of miles away, winter days were short, and sometimes it seemed as though the rain would never stop. This was before SSRIs, but there was always coffee.My mother and her friends would gather at someone's house, sit around the kitchen table, drink coffee, and talk. Looking back as a physician, I think those gatherings served an important purpose. Not because coffee treats depression—it doesn't—but because friendship, conversation, and human connection matter. When the rain was blowing sideways, and you had had enough of your own house, you could always go to Betty's house for a cup of coffee.Of course, there were standards. In our part of Alaska, coffee meant Hills Bros. If Betty served something else, everyone would still drink it gratefully, but it would certainly be discussed. Coffee could generate more conversation than differences in religion. In a town where you could still hear Norwegian spoken on the streets, coffee sometimes seemed like our national beverage. Admittedly, Ketchikan also had far more bars than churches, but that's another story.We Still Meet Over CoffeeThat social role of coffee never disappeared. In many parts of the world, you don't begin a business meeting with business. First comes coffee. You make introductions, ask about family, talk about where you are from, and get to know one another. Then you conduct business.We Americans have made the process more efficient. We pick up a paper cup from the espresso bar, carry it into a conference room, open the laptop, and get right to work. We've kept the coffee, but perhaps we've lost a little of the ritual.Still, coffee shops are thriving, while alcohol use, particularly among younger adults, has been declining. For generations in America, meeting someone often meant, “Let's get a drink.” Increasingly, that drink might be coffee. From a health standpoint, replacing some alcohol with coffee is probably a pretty good trade: a healthier drink and a brighter mind.Even first dates now happen over coffee. Some people think a proper first date should involve dinner, but I'm not convinced. If I'm going to spend two hours discovering whether I like someone, wouldn't I rather find out after they've occupied a few of their adenosine receptors? Give them an espresso, and let's hear their interpretation of Hume.What Coffee Does to Your BrainWhich brings us to caffeine. Caffeine doesn't actually give you energy. Instead, it blocks receptors for adenosine, a chemical involved in the feeling of sleep pressure. As you've been awake longer, adenosine signaling helps tell your brain that you're tired. Caffeine interferes with that message, which is why you feel more alert.My first scientific encounter with caffeine wasn't coffee at all. In the organic chemistry laboratory at the University of Chicago, we isolated caffeine from tea by brewing what may have been the world's strongest cup. It looked completely undrinkable, which was fine because we weren't making afternoon tea; we were doing chemistry.Years later, my friend Simon Majumdar introduced me to proper British builder's tea. Suddenly, I understood the British a little better. Builder's tea is one step removed from containing enough caffeine to keep you awake through one of my podcasts.Do You Really Have to Wait 90 Minutes?You may have heard the popular claim that you should wait 90 minutes after waking before drinking coffee because of cortisol. There is a little real physiology behind the claim. Caffeine can temporarily increase cortisol, and cortisol normally changes around the time we wake up.However, that doesn't prove the 90-minute rule. People who regularly consume caffeine develop substantial tolerance to some of its cortisol effects, and we don't have clinical trials showing that people who wait exactly 90 minutes have better health, better sleep, or better alertness.This is an important lesson that goes well beyond coffee. A biological mechanism is not automatically a medical rule. If waiting 90 minutes makes you feel better, then wait. If you've been drinking coffee shortly after waking for thirty years, sleep well, and enjoy your morning cup, there isn't good evidence that you need to stand beside the coffee maker holding a stopwatch.Coffee Is More Than CaffeineFor years, medicine tended to think about coffee mainly in terms of caffeine. Caffeine stimulates us and can temporarily increase blood pressure, so it seemed reasonable to worry that coffee might be bad for the heart. Then researchers began looking at what actually happened to people who drank coffee over many years, and the story became much more interesting.Coffee contains hundreds of compounds, including chlorogenic acids, which are polyphenols. It also contains other compounds created or changed during roasting. In other words, coffee isn't simply caffeine dissolved in brown water.Large observational studies have found that moderate coffee consumption is associated with lower rates of several health problems, including type 2 diabetes and cardiovascular disease. Some of the most consistent findings involve the liver, where coffee drinking has been associated with lower risks of chronic liver disease, cirrhosis, and liver cancer.Interestingly, some health associations also appear in people who drink decaffeinated coffee. That tells us caffeine cannot be the entire story. Of course, these studies don't prove that coffee prevents disease, and coffee isn't medicine. But they certainly make the old idea that coffee must be bad for us much harder to defend.How You Make Coffee MattersEven the way we brew coffee changes what ends up in the cup. Coffee contains compounds called cafestol and kahweol, and cafestol can raise LDL cholesterol. Boiled and unfiltered coffee retains more of these compounds, while a paper filter removes many of them.That makes a simple invention from 1908 surprisingly important. A German woman named Melitta Bentz wanted a cleaner cup of coffee without grounds and began experimenting with paper filtration. More than a century later, we

For years, beans have suffered from an image problem.They've been called "the poor man's meat," joked about for causing gas, and often relegated to the side of the plate. Yet for thousands of years, beans, lentils, chickpeas, and peas—collectively known as pulses—were among the most important foods on Earth.If bread supplied the calories that built cities, beans supplied much of the protein that sustained them.Long before protein powders and high-protein snack bars, civilizations from Rome to India relied on pulses as an everyday source of nourishment. The Roman laborer's bowl of puls—a hearty porridge often enriched with legumes—was far more representative of daily life than the lavish banquets of emperors. Across the Mediterranean, dishes like pasta e fagioli reflected a simple truth: grains and legumes together formed a remarkably nutritious meal.Modern science has largely caught up with what history already knew.Beans are rich in protein, but they're also packed with dietary fiber, resistant starch, folate, magnesium, potassium, and a remarkable collection of plant compounds that support both heart and metabolic health. Their fiber nourishes the trillions of bacteria living in our colon, producing short-chain fatty acids that help maintain the health of the intestinal lining and may reduce inflammation throughout the body.Perhaps most remarkable is that cultures around the world independently discovered the same dietary pattern. Italy has beans and pasta. India has dal with flatbread. Latin America combines beans with rice or corn. The Middle East gave us hummus. These weren't accidents. They were elegant nutritional solutions developed centuries before anyone knew what an amino acid was.Beans also improve the soil they grow in. Through a partnership with nitrogen-fixing bacteria living on their roots, legumes enrich the earth for future crops. Few foods nourish both the people who eat them and the land that produces them.Today, beans are enjoying a well-deserved renaissance. Heritage producers such as Rancho Gordo have reminded us that beans have flavor, texture, and personality. They're no longer just pantry staples—they're ingredients worthy of the center of the plate.In this week's Fork U podcast, we'll explore how one humble family of plants helped build civilizations, why modern nutrition keeps rediscovering their value, and why the "poor man's meat" may actually be one of the richest foods in human history.Sometimes the greatest superfoods aren't new discoveries.Sometimes they've been quietly simmering in the pot all along.

Olive Oil: The Original SuperfoodBefore electricity lit our homes, olive oil did.For thousands of years, olive oil was far more than something people poured over bread. It fueled lamps, preserved food, moisturized skin, and was used in religious ceremonies. Long before it became a staple of the Mediterranean diet, it helped build civilization.Today, we think of olive oil as healthy. The fascinating part is that people believed it was medicinal long before they understood cholesterol, inflammation, or blood pressure. Sometimes medicine begins with observation. The science simply catches up later.More Than Just FatWhen people hear "olive oil," they often think of fat. That's true, but not all fats behave the same way.Olive oil is rich in monounsaturated fat, the primary fat found in the Mediterranean diet. Rather than worrying about the chemistry, it is more useful to think about what happens inside the body.The real benefit comes from what olive oil replaces.Instead of cooking with butter or shortening, people sauté vegetables with olive oil. Olive oil is better than creamy dressings, and it is part of a delicious vinaigrette. And my favorite is, instead of spreading butter on bread, dipping it in olive oil.Those small substitutions can add up over time.The Science Is ImpressiveOne of the first studies to grab the attention of cardiologists came from Lyon, France. Researchers enrolled people who had already suffered a heart attack and asked one group to adopt a Mediterranean-style diet rich in olive oil.The results surprised almost everyone.Those following the Mediterranean diet had dramatically fewer second heart attacks than those eating their usual diet. It was one of the studies that helped transform olive oil from a traditional food into a modern medical recommendation.Since then, researchers have followed hundreds of thousands of people around the world. Again and again, the same pattern appears. People who regularly consume olive oil tend to have lower rates of heart disease, lower rates of type 2 diabetes, and even lower mortality.Even better, randomized clinical trials such as the PREDIMED study showed that people at high cardiovascular risk reduced their chances of major cardiovascular events by following a Mediterranean diet supplemented with extra-virgin olive oil.Why Does It Work?Scientists think olive oil helps in several ways.When olive oil replaces butter and other saturated fats, LDL cholesterol usually falls. The natural polyphenols found in extra-virgin olive oil also appear to reduce inflammation and help blood vessels relax by improving nitric oxide production. In addition, studies suggest olive oil improves insulin sensitivity and helps protect LDL cholesterol from becoming oxidized, an important step in the formation of artery plaque.No single mechanism explains everything.Instead, several small benefits appear to work together.That is often how nutrition works.Not All Olive Oils Are the SameIf you ask people where the best olive oil comes from, be prepared for a lively discussion.Some prefer the buttery oils from Liguria in Italy. Others enjoy the peppery oils of Lebanon, Greece, or Spain. I have favorites from Arizona, where I lived for years, and from California, where I live now.California also has some of the highest purity standards for olive oil in the world. While olive oil fraud has occurred in some parts of the world, California producers have built a reputation for careful quality control. That gives me confidence in what I'm pouring into my pan.A Small Change Worth MakingNutrition rarely comes down to one magical food.Instead, it comes from making better choices more often.Adding olive oil to your kitchen is one of those simple changes that is easy to enjoy. It makes vegetables taste better, encourages home cooking, and replaces less healthy fats without making meals feel restrictive.Sometimes the healthiest habits are also the most delicious.Olive oil first transformed civilization by lighting the night.Today, it may help illuminate a healthier future—one meal at a time.

Cheese: Humanity's Greatest Delicious AccidentWhat if one of the world's favorite foods happened by accident?That's probably how cheese began.Nobody knows exactly who made the first cheese. Maybe it was a shepherd carrying milk in a bag made from a sheep's stomach. The milk warmed in the sun, natural rennet in the stomach lining began to separate the curds from the whey, and suddenly milk had become something entirely different.Instead of throwing it away, someone tasted it.Transforming CheeseCheese is another example of one of humanity's greatest skills: transforming food. We didn't simply discover food—we learned how to make it safer, preserve it longer, and often make it taste even better.Then, over thousands of years, every culture added its own touch.The English gave us Cheddar. The French perfected Brie and Roquefort. Italy created Parmigiano Reggiano. Greece gave us Feta. Norway even created brown cheese by slowly caramelizing whey into a sweet, nutty delight.Each cheese tells the story of the people who made it.Then there's the science.For years, cheese was criticized because it contains saturated fat. However, modern nutrition research has taught us that cheese is far more complicated than a single nutrient. Cheese contains protein, calcium, beneficial bacteria from fermentation, and a unique food structure that scientists now call the dairy matrix. Interestingly, studies have found that eating cheese is generally neutral—and in many cases modestly protective—when it comes to heart disease.One of my favorite ironies involves Parmesan.People often warn about MSG while happily grating Parmesan over their pasta. Yet Parmesan is naturally rich in free glutamate, the compound responsible for the delicious savory flavor we call umami. Nature discovered that trick long before chemistry gave it a name.Like bread, soup, and cooking itself, cheese reminds us that humans became successful because we learned to transform food instead of wasting it.The next time you enjoy a piece of good cheese, remember you're tasting one of humanity's oldest scientific experiments.This week on FORK U, we'll explore the fascinating history of cheese, how it shaped civilization, why it's healthier than many people think, and why your charcuterie board has a much longer history than Instagram.And on my Substack later this week, we'll dive even deeper into the science behind cheese, fermentation, heart health, the Mediterranean diet, and why nutrition is always more interesting than social media makes it seem.

For years, bread has been the villain of social media.Scroll for a few minutes, and you'll find someone telling you bread causes obesity, diabetes, inflammation, or that humans were never meant to eat it.History tells a different story.Bread didn't weaken civilization.Bread helped build it.From Grass to GreatnessImagine the first person who looked at wild grass and wondered whether those tiny seeds could become food.Nobody knows exactly how bread was invented. Maybe someone mixed crushed grain with water and left it in the sun. Maybe wild yeast landed in the mixture, and it began to bubble. Maybe someone cooked it on a hot rock beside a fire.Whatever happened, one thing is certain.Someone noticed something new and tried it again.That's how science often begins—with curiosity.Bread Changed EverythingOnce people learned how to make bread, life changed.Grain could be stored for months. Families no longer had to search for food every day. Villages grew into towns, and towns became cities.Soon, people could become bakers, builders, teachers, physicians, and merchants because someone else was growing wheat.Bread didn't just feed people.It helped create civilization.Bread Fed EmpiresThe ancient Egyptians depended on bread. Grain storage helped feed the workers who built the pyramids. The Romans knew that keeping bread available helped keep peace in the city. Even today, archaeologists find bakeries and loaves of bread preserved in Pompeii.Later, during the Klondike Gold Rush, my grandfather carried a sourdough starter into Alaska. Thousands of prospectors did the same. That's why experienced miners became known as "Sourdoughs."Bread traveled wherever people went.Then Bread ChangedOver time, bread changed.Factories made bread softer, whiter, and able to last longer on grocery store shelves. It became convenient, but much of what made bread special disappeared.Then, during the 1960s and 1970s, people began baking bread at home again. Books like The Tassajara Bread Book encouraged Americans to rediscover whole grains, sourdough, and fresh bread.Sometimes progress means remembering what we forgot.What Does the Science Say?Not all bread is the same.Whole-grain bread contains fiber, vitamins, minerals, and plant compounds that refined white bread often lacks.Study after study has found that people who eat more whole grains tend to have lower rates of heart disease, type 2 diabetes, obesity, and colorectal cancer. That's one reason whole grains remain an important part of the Mediterranean diet.The question isn't whether bread is healthy.The question is:Which bread?Keep It SimpleOne of the simplest meals is still one of the best.Take a slice of whole-grain bread, add good extra-virgin olive oil, and enjoy it with a bowl of soup or a Mediterranean meal. It doesn't need to be complicated.Some foods have survived for thousands of years for a reason.Bread is one of them.This week in my Substack, I dive much deeper into the history of bread, how it helped build civilization, why whole grains continue to be recommended by nutrition research, and why bread has become one of the most misunderstood foods on social media.You can read the full article on drsimpson.com, and if you're looking for Mediterranean recipes—including homemade bread, soups, and healthy meals—you'll find them at terrysimpson.com.

Soup: The Mediterranean Diet in a BowlOver the past few weeks, many of us have been looking at our refrigerators a little differently. News about Cyclospora, E. coli, and other foodborne outbreaks has made people nervous about fresh vegetables and herbs. At the same time, grocery stores are filled with expensive electrolyte drinks, protein broths, and wellness beverages promising to keep us healthy. However, there is a much simpler solution that has been around for thousands of years. Make soup.It may sound almost too simple, but soup remains one of the healthiest meals we can prepare. In fact, if someone asked me to build the perfect meal using what we know today about nutrition, I'd probably start with a pot of soup. Add onions, garlic, beans, tomatoes, leafy greens, herbs, perhaps a little chicken or fish, a drizzle of olive oil, and serve it with a slice of whole-grain sourdough. You've just created what I like to call the Mediterranean diet in a bowl. And to prove you can do that from any cuisine, my favorite soup is Dahl - and click here for the recipe.The First Food SafetyMore importantly, soup has always been much more than comfort food. Throughout history, people discovered that boiling food made it easier to digest and often safer to eat, even though they had no idea bacteria or parasites existed. Today, we know that proper cooking destroys organisms such as Cyclospora and many harmful bacteria, making soup not only delicious but also one of humanity's oldest food safety techniques.Furthermore, soup is one of the best ways to reduce food waste. We all have that refrigerator drawer that starts out as a crisper and eventually becomes what I call the "future soup drawer." A few carrots, some celery that's lost its crunch, half an onion, spinach that's beginning to wilt, or herbs that are no longer picture-perfect can all become tomorrow's lunch instead of tomorrow's compost. Rather than throwing them away, let them contribute their flavors to a pot of soup.Another reason I love soup is that it naturally brings together many of the foods we should be eating more often. Beans provide fiber and plant protein. Vegetables add vitamins, minerals, and phytochemicals. Herbs contribute remarkable flavors without relying on excess salt. A little olive oil adds healthy fats, while broth provides hydration along with naturally occurring electrolytes. Unlike many products marketed as "wellness foods," soup doesn't need fancy packaging or celebrity endorsements. It has been quietly doing its job for thousands of years.Better with Age - like meThen there's one final reason soup deserves a place in every kitchen.It gets better.Few foods improve overnight the way soup does. The flavors continue to develop, the broth becomes richer, and somehow the entire pot tastes more complete the next day. That's one reason soup has always been one of the original meal-prep foods. Long before social media was teaching us how to prepare lunches for the week, families simply made one large pot of soup and enjoyed it for several meals.Of course, every family develops its own favorites. In our house, taco soup is always a winner. It starts with onions, garlic, olive oil, canned beans, tomatoes, cumin, coriander, and chili spices before being finished with fresh lemon juice, avocado, and crushed whole-grain tortilla chips. It's hearty, inexpensive, packed with fiber, and it disappears quickly whenever I make it.Perhaps that's why every civilization eventually invented soup. It stretches ingredients, reduces waste, nourishes families, hydrates naturally, and transforms simple foods into something extraordinary. Sometimes the oldest ideas remain the smartest ones.This week on Fork U, we're diving into the remarkable history and science of soup, including why every civilization created its own version, why soup may be the Mediterranean diet in a bowl, why it often tastes better the next day, and even why a proper French consommé is one of the greatest achievements in culinary science.For the full story, listen to this week's episode of Fork U at drsimpson.com.And if you'd like some of my favorite soup recipes—including taco soup, Mediterranean-inspired soups, and other healthy meals—you'll find them at terrysimpson.com.

Fire didn't just change dinner. It changed us.If I asked you what made us human, you might say language. Or tools. Maybe agriculture. All of those changed our species, but I think one discovery came even earlier—and it may have been the most important of all.Fire.Not because it kept us warm.Not because it frightened predators.But because it cooked dinner.At first glance, that might seem like an odd claim. After all, cooking is something we do every day without much thought. However, when you look at the science and the history together, cooking becomes one of the most remarkable innovations in human evolution.More importantly, it changed far more than the taste of our food.For more in-depth discussion, go to my Substack channel at DrSimpson.comCooking Changed the Food We AteBefore humans learned to control fire, food was difficult work.Raw meat is tough. Many roots are fibrous. Grains are nearly impossible to eat without processing, and many plants lock away their nutrients behind tough cell walls.Then everything changed.Cooking unfolds proteins, softens connective tissue, gelatinizes starches, and breaks down plant cell walls. As a result, our digestive system has less work to do, and we gain access to more of the calories and nutrients already present in the food.In other words, cooking didn't create nutrition.It unlocked it.Then Cooking Made Food SaferHowever, the story doesn't stop with nutrition.Long before anyone understood bacteria or parasites, early humans discovered something through observation. Food cooked over a fire made people sick less often.Today we know why.Heat destroys many harmful bacteria. It kills many parasites. It reduces the risk of foodborne illness.Consequently, cooking likely became one of humanity's earliest public health tools.Groups that regularly cooked their food would have lost fewer children to severe diarrheal disease, had healthier adults, and retained more of the calories they worked so hard to obtain.That is a tremendous evolutionary advantage.Flavor Matters More Than You ThinkThere is another benefit that often gets overlooked.Cooking made food taste better.That may sound obvious, yet it is incredibly important.Humans don't simply eat because food contains nutrients. We eat because food is enjoyable. Cooking creates hundreds of new flavor compounds through browning reactions that simply don't occur in raw food.Think about the smell of fresh bread.Or grilled steak.Or roasted coffee.Those aromas are products of cooking.Likewise, a cooked potato bears little resemblance to a raw one. The texture changes. The flavor changes. Even the way our bodies digest the starch changes.Fire didn't just feed us.It invited us back for another meal.The Real Lesson from EvolutionUnfortunately, some people oversimplify this fascinating story.They argue that because meat was important during human evolution, the ideal modern diet must consist almost entirely of meat.The science doesn't support that conclusion.Cooking improved meat.It also improved roots.Cooking made tubers tasty.Then cooking softened grains.And finally, it made legumes digestibleThe evolutionary advantage wasn't eating one perfect food.Instead, it was becoming adaptable enough to thrive on many foods by transforming them with fire.That is a much more interesting story—and one much better supported by the evidence.Why This Still Matters TodayEven in modern kitchens, we continue using the same principles our ancestors discovered thousands of years ago.We cook food to improve digestibility.And we cook food to improve safety.We cook food because it tastes better.Most importantly, we gather around meals because cooking has always been about more than calories.It has always been about family, community, and sharing stories.Perhaps civilization didn't begin with the first city.Perhaps it began around the first campfire.

The Bank of Muscle: Why Your Real Retirement Account Isn't Your 401(k)I used to think retirement planning was all about money. Put enough away, let compound interest do its thing, and someday you'll enjoy the rewards. As I've gotten older, however, I've come to appreciate another form of savings that may be just as important.It's your muscle.Nobody reaches eighty-five and wishes they had less of it. Instead, people wish they could get out of a chair more easily. They wish they could carry groceries, travel, garden, and play with grandchildren. In other words, they wish they had more reserves.That's really what muscle buys us.Dad's First Retirement AccountI was fortunate. My father lived nearly ninety-nine years old, and he didn't simply survive. He lived.At eighty-five, Dad was walking three and a half miles every day. That's remarkable. Many people half his age don't walk that much. He had survived several heart attacks over the years, but he had reserves. Looking back, I realize that making it to eighty-five is one thing. Reaching eighty-five healthy enough to begin the sprint into your nineties is something else entirely.Dad didn't do anything exotic. He wasn't biohacking. He wasn't chasing supplements. He wasn't optimizing every laboratory value.He walked.And my mother cooked.Their meals weren't complicated. They enjoyed meat, potatoes, vegetables, soups, and desserts. They enjoyed life together. In hindsight, Dad was making deposits into his Bank of Muscle every day without ever calling it that.Then Life ChangedAs my mother's dementia slowly progressed, things began to fall apart. Dad stopped walking, not because he wanted to, but because he didn't want to leave Mom alone. He worried she might wander. At the same time, Mom stopped cooking.Breakfast became something out at a diner. Lunch might be a sandwich. Dinner often became cereal.I watched them both lose weight.Then I got the phone call no child wants."Dad's in the hospital. He fell and couldn't get up."The fall wasn't the problem. Falls happen. What concerned me was that Dad no longer had enough reserve.After a couple of weeks in rehabilitation, I convinced him to move into an assisted living center close to our house. He wasn't thrilled with the idea, but something remarkable happened. Once Mom entered memory care and Dad had regular meals again, he began to thrive.He complained constantly about the food while gaining seventeen pounds. But he made friends and was always talking to someone or another. I would drive by and see him talking to anyone, from former Supreme Court Justice Sandra Day O'Connor, who lived there, and had a crush on my dad. My dad was making sure his neighbor got the newspaper, and yet he continued to complain about the food. All while gaining 17 pounds the first year.Twice a week, I would take Dad to dinner, and we would split a steak.The waitresses had a standing joke. They would ask him whether he wanted the kale salad.Dad would smile and say, "I grew up in an orphanage in Alaska. We grew kale, but we fed it to the cows. I'll eat the cow."He charmed every waitress in town.Eventually, after Mom died, Dad moved back home to Oregon and lived independently again. Visiting Angels helped with meals and companionship, but he was back in his own house.Looking back, I learned two things.Food matters.Muscle matters.Frailty Is the EnemyWe spend a lot of time talking about heart disease, cancer, cholesterol, and blood pressure. Those are important. However, frailty is another great enemy of aging.Frailty steals independence.One broken hip can change everything. A fall that would have been a nuisance at sixty can become life-changing at eighty-five. Muscle gives us reserve, and reserve allows us to recover.My father didn't avoid every setback.He survived them.That's what reserve does.Protein Helps, But It Isn't MagicThe supplement industry would love us to believe that a powder is all we need. Unfortunately, muscles didn't get the memo.Protein matters, especially as we age. Most experts recommend older adults consume about 1.2 to 1.5 grams of protein per kilogram of body weight each day, spread throughout the day rather than eaten all at once at dinner. For many people, that means aiming for twenty-five to thirty grams of protein at each meal.¹However, protein alone isn't enough.A large meta-analysis found that protein supplementation without resistance exercise had limited effects on strength and muscle mass. In contrast, combining protein with resistance exercise produced meaningful improvements.²In other words, muscles need both building blocks and a reason to keep existing.Exercise Doesn't Have To Be FancyWhen people hear "resistance exercise," they often picture bodybuilders.That's not what the science requires.Walking hills counts.Gardening counts.Resistance bands count.Swimming counts.Carrying groceries counts.Yoga counts.For me, yoga became the answer.I'm not a gym person. Exercise isn't my hobby. I don't wake up every morning excited to work out. I do yoga because I know future Terry will appreciate it.I'm not training for the Olympics.I'm training for my eighties.Real Food Still WorksWhey protein is probably the most studied supplement because it's rich in leucine, an amino acid that helps stimulate muscle protein synthesis. As we age, muscles become less sensitive to that signal, which is why getting enough leucine becomes increasingly important.¹Fortunately, you don't need expensive powders.Eggs, fish, dairy products, soy, beans, chicken, and meat all provide excellent protein.Personally, whey protein and I are not close friends. I've had lactose intolerance for years, and the slower gut that comes with GLP-1 therapy has made me even less tolerant of many whey products. Add stevia, sugar alcohols, and various flavorings, and my intestines politely object.Instead, I use egg protein or plant proteins. I avoid stevia because it tastes like electrical tape to me, and I don't need a chemistry experiment in a shaker bottle.Still, I recognize supplements have a role.If you're on a GLP-1 medication and eating less, or if you're simply busy, a protein shake or bar can be a useful tool. They aren't magic.They're convenient.A Father's WisdomAfter Mom died, Dad came to live with me in California. By then, I had discovered yoga.Dad teased me about it at first.Then one day, he looked at me and said something I've never forgotten."I think you doing yoga is great. You're the right age. Doing this now is important. If yoga is what you like, buy all the spandex you want and keep doing it."Those words stayed with me.You're the right age.Doing this now is important.If you're lucky, your parents give you wisdom throughout your life. When you're young, you roll your eyes. Later, you realize those words become part of who you are.Money gets spent.Wisdom gets carried.Dad wasn't telling me to do yoga.He was telling me to keep moving.Make DepositsEvery age has different priorities.At twenty-five, you may be building a career.At forty-five, you may be raising children.At sixty-five, you may be protecting your muscle.At eighty-five, you may simply want enough reserve to get out of a chair and go to dinner with your family.The body doesn't really care whether those deposits come from yoga, barbells, swimming, pickleball, or walking.It only cares that you keep making deposits.Because someday you'll need to make a withdrawal.Life guarantees that.When that day comes, you'll be grateful for every walk, every stretch, every protein-rich meal, and every little thing you did, not because you loved doing them, but because they built reserve.Healthy aging isn't about dying young as slowly as possible.It's about building enough reserve so that when life knocks you down, you still have enough strength to get back up.And that may be the most important retirement account you'll ever own.ReferencesBauer J, Biolo G, Cederholm T, et al.

If you read some low-carb sites, or Gary Taub's books, you will find the contention that the food pyramid - the last one being in 2011 - put America into a low fat, high carb diet responsible for today's obesity. That the government food pyramid misled a generation of people, and because we faithfully follow it, we became fat.The problem is, that isn't the case, but I want to go back in time and see why we have those government issued guidelines, and see where we are today.Dietary RecommendationsThe first major food guide appeared in 1943. It wasn't even a pyramid. It was called the Basic Seven.Created to prevent malnutrition and maintain stamina during World War II, it categorized foods into seven groups and served as the precursor to the modern food pyramid:1: Green and Yellow Vegetables (e.g. leafy greens, green beans, carrots).2: Oranges, Tomatoes, Grapefruit (or other raw greens high in Vitamin C).3: Potatoes and Other Vegetables/Fruits (e.g., apples, potatoes, beets).4: Milk and Milk Products (e.g. fluid milk, evaporated milk, cheese).5: Meat, Poultry, Fish, or Eggs (as well as plant-based proteins like dried beans and nuts).6: Bread, Flour, and Cereals (focusing on whole grain or enriched varieties).7: Butter and Fortified Margarine (specifically noted to provide necessary calories and Vitamin A during rationing).The Basic FourThese came out in 1956 to help a growing America. doctors worried about malnutrition and vitamin deficiencies. Diseases such as pellagra, rickets, and scurvy were still being treated.A breakdown of the 4 food groups and how they currently fit into a balanced, healthy routine:1. Fruits & Vegetables 🥦Focus: Whole forms (fresh, frozen, or canned without added sugars).Benefits: Packed with essential vitamins, minerals, and dietary fiber.Goal: Aim to make half your plate fruits and vegetables at meal times.2. Grains 🌾Focus: Whole grains (oats, brown rice, whole-wheat bread).Benefits: Provides vital carbohydrates and fiber for sustained energy.Goal: Make at least half your daily grains "whole" to get the most nutritional value.3. Protein 🥩Focus: Lean proteins like poultry, fish, eggs, legumes (beans/peas), nuts, and seeds.Benefits: Builds muscle mass, repairs tissues, and keeps you full.Goal: Include a portion of protein with every meal to keep metabolism regulated.4. Dairy 🥛Focus: Milk, yogurt, and cheeses (or calcium-fortified plant alternatives).Benefits: Crucial source of calcium and vitamin D for strong bones and teeth.Goal: Opt for low-fat or unsweetened varieties whenever possible to limit excess sugar1979 What to AvoidDirectly after the Basic Four, the USDA introduced the Hassle-Free Daily Food Guide (1979). The Hassle-Free Daily Food Guide (1979–1984)What changed: It kept the core Basic Four, but added a fifth group: Fats, Sweets, and Alcohol.Purpose: This was the first time a group was explicitly highlighted for the public to consume only in moderation.The transition away from the Basic Four marked a major shift in government policy: instead of just telling Americans to eat enough nutrients to avoid deficiencies, the focus changed to preventing chronic illnesses by telling people what to limit.The Food Guide Pyramid (1992–2005)The first guide to feature highly specific daily serving sizes across six distinct categories. Grains formed the massive base (6–11 servings), followed by fruits and vegetables, then dairy and meat, with fats/sweets resting at the tiny top peak.Fair Criticisms of the Food PyramidNone of this means the Food Pyramid was perfect.In fact, there are several reasonable criticisms. First, the pyramid did not do a great job distinguishing between whole grains and refined grains. A bowl of steel-cut oats is different from a sugary breakfast cereal, but both could look similar on a simple graphic. Likewise, the pyramid often treated fats as a single category when we now know that olive oil, nuts, and fish are different from trans fats and highly processed shortening.In addition, agriculture and food industry groups had influence over the process. That should not surprise anyone. Food policy has always involved scientists, government agencies, farmers, food manufacturers, and politicians. As a result, some recommendations reflected compromises rather than perfect science. That is a fair criticism, and it is one reason nutrition advice continues to evolve.However, we should also be honest about today's environment. While many criticize the influence of industry on older food guides, we now live in an age where nutrition advice often comes from influencers, supplement companies, podcasters, social media personalities, and people selling books, courses, or products. In other words, we have not eliminated outside influences. We have simply changed who those influences are. Therefore, the challenge today is the same as it has always been: separating evidence from marketing.Most importantly, the biggest problem facing Americans today is not that we are following an outdated Food Pyramid. Instead, it is that inexpensive, highly processed, calorie-dense foods surround us that require little preparation and are available everywhere. At the same time, portion sizes have increased, sugary beverages have become common, restaurant meals have grown larger, and fewer people cook regularly at home. As a result, we consume more calories than previous generations, while often moving less.The Real Reason We Became HeavierThe Food Pyramid did not make America fat.That story is appealing because it is simple, but simple stories are not always true. The reality is that obesity developed while most Americans were not following the Food Pyramid at all. Instead, we were eating larger portions, drinking more calories, consuming more ultra-processed foods, dining out more often, and cooking less frequently.At the same time, our food environment changed dramatically. Food became cheaper, more convenient, and available nearly everywhere. Consequently, it became much easier to consume excess calories without even noticing it.The real lesson is not that one graphic ruined America's health. Rather, the lesson is that every generation faces new food challenges and tries to solve them with the best knowledge available at the time. Some recommendations age well, while others do not. Yet one message has remained remarkably consistent for decades: eat more fruits and vegetables, include beans and whole grains, enjoy fish and other healthy proteins, cook when you can, and share meals with people you care about.That advice may not fit neatly into a pyramid, but it has stood the test of time.

How We EatMost of us think we know what we eat. However, nutrition researchers have learned a frustrating lesson over the years: asking people what they ate yesterday is often less accurate than anyone would like. Although food diaries and surveys can provide useful information, memories are imperfect, snacks are easily forgotten, and portion sizes tend to grow smaller in retrospect. Consequently, some of the most important nutrition research takes place in a setting that is both expensive and surprisingly simple—a metabolic ward, where every meal is prepared, every serving is weighed, and every leftover bite is measured.That approach is exactly what researcher Kevin Hall and his colleagues used in a landmark study at the NIH. Participants were given two different diets, one based largely on ultra-processed foods and another built around minimally processed foods. Importantly, the volunteers could eat as much as they wanted. Nobody instructed them to count calories, restrict portions, or lose weight. Nevertheless, participants consumed about 500 more calories per day when eating the ultra-processed diet. The same people, living in the same environment, produced dramatically different results simply because the food changed.Obesity in the US and Ultra-Processed FoodsAs a result, the study raised an intriguing question. If ultra-processed foods can influence calorie intake to that degree, why isn't everyone obese? After all, ultra-processed foods make up a large portion of the modern food supply. Grocery stores are filled with them, convenience stores specialize in them, and many restaurants depend on them. Yet despite widespread exposure to the same food environment, some people seem relatively unaffected while others struggle with appetite, cravings, and weight gain.Prego and Vanishing CaloriesTo understand how we arrived here, it helps to step back a few decades. During the latter half of the twentieth century, food companies increasingly turned to scientists, statisticians, and sensory researchers to understand consumer behavior. One of the most influential figures was Howard Moskowitz, a researcher who discovered that there was no single perfect food. Instead, he found that consumers tended to cluster into different preference groups. Some people preferred sweeter products, others wanted more texture, and still others favored stronger flavors. As a result, food manufacturers stopped searching for one ideal product and began creating multiple versions designed to appeal to different consumers.Meanwhile, another researcher, Steven Witherly, focused on a different question. Rather than asking what people preferred, he explored why certain foods were so rewarding. His work highlighted the importance of texture, aroma, crunch, temperature, and mouthfeel. In other words, food is not simply taste. Instead, it is a complex sensory experience involving multiple signals that influence how satisfying a meal feels.One of Witherly's most memorable concepts is known as vanishing caloric density. Certain foods, particularly puffed snacks, dissolve quickly in the mouth and create the sensation that they have almost disappeared. Although the calories remain, the physical experience of eating them can feel surprisingly brief. Consequently, these foods may be easier to consume in larger quantities before the body's normal satiety signals fully catch up. While that does not make such foods inherently bad, it does help explain why some snacks seem to empty themselves once the bag is opened.Ultra-Processed Foods and GLP-1At the same time, the modern food environment has become remarkably effective at attracting attention. Food manufacturers optimize texture, flavor, aroma, and convenience, while consumers encounter those products virtually everywhere. Therefore, the challenge is not simply one of personal responsibility. Biology, environment, culture, sleep, stress, and genetics all influence how people respond to food. Some individuals appear naturally protected, whereas others experience stronger reward signals and greater susceptibility to cravings.Interestingly, the recent rise of GLP-1 medications has provided another perspective on appetite. Many patients describe a quieter relationship with food, noting that foods which once demanded attention suddenly seem less compelling. The food itself has not changed; rather, the brain's response to it has shifted. Consequently, these medications have highlighted something obesity researchers have suspected for years: appetite is not merely a matter of willpower. Instead, it reflects a complex interaction between biology and an increasingly sophisticated food environment.Ultimately, Kevin Hall's study gave us an important clue about what happens when people are exposed to different types of food. Howard Moskowitz showed how companies learned to identify consumer preferences, while Steven Witherly helped explain why certain foods are so appealing in the first place. Together, their work offers a fascinating glimpse into the science behind modern eating and raises a question that may be more interesting than why some people gain weight. Perhaps the real mystery is why some people seem largely unaffected by an environment that was designed to capture our attention.For a deeper discussion of food engineering, the bliss point, vanishing caloric density, and what this means for appetite in the era of GLP-1 medications, listen to this week's episode of Fork U.

Taste Isn't What You Think It IsMost people believe taste happens on the tongue. That idea seems obvious because food enters the mouth, the tongue recognizes flavors, and the brain decides whether something tastes good or bad. However, modern science has revealed a much more fascinating story. Taste receptors are scattered throughout the body, including the stomach, intestines, airways, pancreas, and even tissues associated with the nervous system. Consequently, what we call taste is actually part of a much larger surveillance system that helps us detect nutrients, toxins, microbes, and potential threats before they become serious problems.Before we explore those hidden taste receptors, though, we need to separate taste from smell. Most people use the words interchangeably, yet they are remarkably different systems. In fact, if you've ever had a bad cold, you've already experienced the difference firsthand.Why Expensive Wine Tastes Like Grape Juice With a Stuffy NoseImagine spending a fortune on a bottle of Screaming Eagle wine. A sommelier describes notes of blackberry, cedar, tobacco, leather, and dark cherry while swirling the glass dramatically. Now pinch your nose shut and take a sip. Suddenly, those elegant descriptions become much harder to appreciate, and the wine starts tasting suspiciously like grape juice.The reason is simple. Your tongue detects only a handful of basic categories: sweet, salty, sour, bitter, and umami. Meanwhile, your nose identifies the thousands of aromatic compounds that make strawberries taste different from cherries or Cabernet different from Merlot. Therefore, much of what we casually call taste is actually smell working behind the scenes. Without smell, a wine tasting becomes a costly visit to a Welch's grape juice stand.This distinction matters because it helps explain why taste receptors throughout the body are not there for pleasure. Instead, they exist to gather information.Sweet Means Calories, and Your Body Pays AttentionFor most of human history, finding calories was difficult. As a result, sweet flavors became associated with survival. A ripe fruit, a handful of berries, or a cache of honey represented valuable energy in a world where starvation was a constant threat. Because of that evolutionary pressure, the body developed specialized receptors to detect sweetness and rapidly prepare for incoming fuel.The story becomes even more interesting once food reaches the intestine. Sweet receptors known as TAS1R receptors help stimulate the release of incretin hormones such as GLP-1 and GIP. Consequently, eating sugar creates a different physiologic response than receiving glucose through an IV. The tongue detects sweetness, the gut begins releasing hormones, the pancreas prepares insulin, and the brain activates reward pathways. In contrast, intravenous glucose raises blood sugar, but skips much of the sensory experience that evolution spent millions of years refining.Warm apple pie and an IV bag may deliver similar sugar molecules. Nevertheless, your body treats them as entirely different events.Umami: The Taste the Japanese Taught the WorldWhile sweet and bitter flavors are easy to recognize, umami remained poorly understood until Japanese scientists formally described it in the early twentieth century. The term refers to a savory, rich taste associated with glutamate and certain amino acids. Soy sauce, mushrooms, Parmesan cheese, tomatoes, broths, and many fermented foods owe much of their appeal to umami.From an evolutionary standpoint, umami serves an important purpose. Protein is essential for growth, repair, reproduction, and survival, so recognizing protein-rich foods provided a significant advantage. Consequently, the body evolved receptors specifically designed to detect those compounds. Modern scientists call them TAS1R1 and TAS1R3 receptors. Our ancestors simply recognized them as signs that dinner was likely worth pursuing.Growing up in Ketchikan, Alaska, I had a slightly different perspective on some of these foods. The first time somebody enthusiastically explained sushi to me, my immediate reaction was, "That's bait." Fortunately, the Japanese had grander plans for raw fish than I did.Why Children Hate BroccoliParents often assume children reject vegetables because they are stubborn. Evolution suggests another explanation. Many toxic plant compounds are bitter, and bitterness frequently serves as nature's warning label. Therefore, children are generally more sensitive to bitter flavors than adults. Their bodies are essentially operating a heightened food safety program.As people age, repeated exposure teaches the brain that many bitter foods are safe and even beneficial. Coffee, tea, dark chocolate, kale, Brussels sprouts, and beer all require overcoming an instinctive caution signal. Adulthood, in many ways, involves learning which bitter things deserve a second chance. Moreover, many of those foods contain nutrients, fiber, and bioactive compounds associated with better health.This is one reason I smile whenever someone declares kale is poison. The statement may reveal more about the speaker's bitter receptors than about kale itself.Babies, Honey, and a Healthy Fear of FoodInfants face a different challenge. During the first months of life, stomach acid production is lower than in adults. Consequently, babies are more vulnerable to certain organisms that older children and adults can handle without difficulty. This difference explains one of the most important feeding rules in pediatrics: do not give honey to infants under one year of age.Honey can contain spores of Clostridium botulinum. In adults, stomach acid and a mature intestinal environment generally prevent those spores from causing problems. However, infants lack many of those defenses. Therefore, infant botulism remains a genuine concern, despite honey's reputation as a natural food. Once again, evolution reminds us that caution often exists for a reason.The Stomach: Bouncer, Judge, and ExecutionerOne of the most surprising discoveries in recent years is that the stomach contains bitter taste receptors known as TAS2Rs. These receptors do not evaluate flavor. Instead, they help assess what has arrived and determine how aggressive the digestive system should respond. When bitter compounds appear, gastric emptying may slow, giving stomach acid additional time to destroy microbes and process potentially hazardous material.I learned this lesson personally during a trip to Tijuana. Someone handed me a Clamato loaded with raw shellfish. At the time, it tasted wonderful. Several hours later, however, my stomach conducted a thorough review of the situation. The acid weighed in, the receptors filed their reports, and the immune system apparently demanded immediate action. The resulting decision was swift, unanimous, and memorable.Evolution does not care about dignity. Survival remains the only vote that counts.Your Sinuses Listen to BacteriaPerhaps the strangest discovery involves bitter receptors in the airways and sinuses. Researchers have found that certain receptors can detect chemical signals used by bacteria to communicate. In other words, cells lining your sinuses may effectively eavesdrop on microbial conversations before those microbes establish a significant foothold.Once those signals are detected, defensive mechanisms begin activating. Nitric oxide production increases, antimicrobial responses strengthen, and mucus clearance accelerates. Consequently, these receptors function less like taste buds and more like security personnel monitoring suspicious activity. The fact that a system originally associated with tasting food can also help defend against infection highlights how versatile these ancient sensors have become.The Real Story of TasteFor generations, we assumed taste existed primarily for enjoyment. While pleasure certainly plays a role, the larger story is far more interesting. Taste receptors help identify calories, protein, toxins, bacteria, and environmental threats. Furthermore, many of these receptors appear to have evolved as general chemical sensors long before they became associated with dining.The next time you enjoy a slice of pie, a bowl of sushi, a glass of wine, or even a serving of broccoli, remember that your tongue is only one participant in the conversation. Your stomach is paying attention. Your intestines are paying attention. Even your sinuses may be paying attention. Long before nutrition labels, food influencers, and restaurant reviews existed, the body developed its own remarkably sophisticated system for deciding what was worth eating and what should be avoided.That's not just taste. That's survival.

Type 2 Diabetes, Bariatric Surgery, Fasting, and GLP-1s: What We Finally Learned About a Disease We Thought We UnderstoodFor years, I watched something happen in bariatric surgery that made very little sense, according to the medical textbooks of the time.Patients with type 2 diabetes would undergo surgery, and within days, their blood sugars would improve dramatically. Some would leave needing far less insulin. Others would stop insulin entirely. Many of them would eventually remain off diabetes medications for years.Now here is the important part:They had not yet lost significant weight.That observation mattered enormously.Because if diabetes improvement were simply the result of fat disappearing from the body over time, then blood sugar should improve slowly over months as weight comes off.But that was not what we saw.Instead, patients barely eating — sipping broth and protein shakes while recovering from surgery — were suddenly metabolically different almost immediately.At the time, we knew it worked. What we did not fully understand was why.And honestly, that story tells you something important about medicine and science: sometimes clinical medicine notices the truth before biology fully explains it.For decades, type 2 diabetes was often taught in very mechanical terms. You gained weight. You became insulin-resistant. The pancreas worked harder and harder until it “burned out.” Then you needed insulin.That explanation was not entirely wrong. However, it was incomplete. Furthermore, it encouraged a kind of fatalism around type 2 diabetes, as though progression were inevitable and irreversible for everyone.Then, bariatric surgery complicated the narrative.Meanwhile, researchers like Professor Roy Taylor at Newcastle University began developing a much more dynamic understanding of what was actually happening inside the liver and pancreas.And suddenly, many of the strange things bariatric surgeons had observed for years started making sense.The Problem May Not Be Sugar AloneOne of the most common mistakes in nutrition discourse is assuming that blood sugar itself is the disease.It is not.Blood sugar is often the visible signal of a much larger metabolic problem involving:the liver,the pancreas,adipose tissue,appetite signaling,inflammation,gut hormones,and the brain itself.Now, to be fair, refined carbohydrates and ultra-processed foods absolutely can worsen insulin resistance and glucose control. Sugary beverages, highly refined starches, and hyperpalatable processed foods create enormous metabolic stress for many people.However, reducing the entire disease of type 2 diabetes to “sugar is poison” oversimplifies what is actually a highly complex biological system.If carbohydrates alone caused diabetes, then traditional Mediterranean populations consuming beans, lentils, intact grains, and fruit would have universally developed severe metabolic disease. Yet many of those populations historically had some of the best cardiovascular and metabolic outcomes in the world.Similarly, bariatric surgery would not improve diabetes before substantial fat loss occurred.Something deeper was happening.Roy Taylor and the Twin Cycle HypothesisRoy Taylor’s Twin Cycle Hypothesis is one of the most elegant modern explanations for type 2 diabetes.The theory proposes that type 2 diabetes develops through two interconnected metabolic cycles, involving excess fat accumulation in organs not designed to store large amounts of fat.First comes the liver. When caloric intake chronically exceeds what the body can safely store in adipose tissue, fat begins accumulating in the liver. Eventually, the liver becomes insulin-resistant. Now the liver starts misbehaving metabolically. Instead of calming down glucose production when insulin is present, the liver continues to release glucose into the bloodstream. At the same time, it exports excess triglycerides and fat particles into circulation.This creates a vicious cycle:more liver fat,more insulin resistance,higher insulin levels,more glucose production.Then comes the second cycle. Those excess fat particles eventually accumulate in the pancreas itself. And that is where the beta cells begin struggling.The Beta Cell Is Not Simply “Burned Out”For years, we talked about the pancreas as though it simply became exhausted.However, newer biology suggests something more complicated — and more hopeful.Beta cells produce insulin, which is a protein. Proteins must be folded properly inside the cell before they can be packaged and secreted.Under chronic metabolic stress — high glucose levels, elevated fatty acids, inflammation, oxidative stress — the protein-folding machinery inside the beta cell begins malfunctioning.Some insulin molecules become misfolded.Now imagine a factory assembly line where defective products begin to accumulate faster than workers can remove them.The system clogs. The beta cell experiences what is called endoplasmic reticulum stress, or ER stress. In simple terms, the protein-processing machinery becomes overloaded.At first, the cell adapts. It slows production. And the cell will activate repair systems. To clear damaged proteins.But if the stress continues long enough, the machinery begins failing. Some beta cells become dysfunctional. As a result, some become metabolically suppressed. They stop making insulin. Some dedifferentiate, meaning they stop functioning normally. And eventually some undergo apoptosis: programmed cell death.That distinction matters enormously. Because it suggests that not every beta cell is permanently destroyed early in the disease. Some are simply overwhelmed.Why Fasting Sometimes WorksThis may help explain why fasting improves type 2 diabetes in some patients.Fasting reduces metabolic demand.Less glucose enters the system.Less insulin is required.The liver produces less glucose.The pancreas experiences less pressure.In effect, fasting may temporarily reduce the metabolic traffic jam overwhelming the beta cells.Now, some people online treat fasting almost like a mystical cure for diabetes. I think that is an exaggeration.The body is not achieving enlightenment because somebody skipped breakfast.The likely benefit is much more practical:Reduced metabolic overload allows stressed systems to recover function.And clinically, we do see this. Some patients improve dramatically with fasting or aggressive caloric restriction. However, fasting is not universally successful because not all patients have the same remaining beta-cell reserve. Some patients have substantial recoverable function left. Others have experienced years of apoptosis and structural loss.That is one reason newly diagnosed patients often respond far better than patients with decades of poorly controlled diabetes.Duration matters. Furthermore, what happens after the fasting matters enormously.If someone fasts aggressively, but then returns immediately to hyper-palatable ultra-processed food, liquid calories, and chronic overnutrition, the same metabolic stress returns.Which brings us to an important point.The Real Goal Is Not Carb EliminationThis is where I part ways somewhat with the more absolutist low-carb community.Low-carb diets help many patients reduce caloric intake and improve glucose control. That part is real.However, when you look at the broader evidence, the deeper lesson is probably not:“Carbohydrates are evil.”The deeper lesson is: eat less, eat better, and create a sustainable metabolic environment that the body can actually manage long term.And this is where Mediterranean-style dietary patterns continue to shine.Why the Mediterranean Diet Works So WellOne of the strangest developments in modern nutrition culture is the fear surrounding whole grains and legumes.Beans somehow became suspicious.Oatmeal became controversial.Meanwhile, the modern industrial food environment quietly engineered ultra-processed calorie delivery systems powerful enough to overwhelm normal satiety pathways entirely.Perspective matters.After bariatric surgery, once patients had healed from the immediate postoperative phase, many naturally transitioned toward what was essentially a Mediterranean-style eating pattern.Not because it was trendy.Because clinically it worked. But because patients tolerated it well. Their weight stabilized more successfully. In addition, cardiovascular risk factors improved. And perhaps most importantly, they could sustain it.That last point matters more than anything else in nutrition.The Mediterranean diet works because it aligns well with human physiology:high fiber,intact foods,lower caloric density,reduced ultra-processed food burden,improved satiety,favorable effects on the microbiome,and long-term sustainability.Importantly, carbohydrates behave differently from rapidly absorbed refined starches and sugary beverages.Food structure mattersFiber matters.Satiety matters.Context...

The Science of Hangovers: Why Your “Cure” Probably Doesn’t WorkYou wake up thirsty.Then, almost immediately, you realize your head hurts. Your stomach feels unstable. The room is too bright. Your mouth tastes like regret and old wine corks. Furthermore, your intestines suddenly decided today is the day they become extremely efficient.In other words, you have a hangover.Now, hopefully, this is not a regular occurrence. Nevertheless, most adults eventually experience one. The evening starts innocently enough: good friends, great conversation, maybe a cocktail before dinner. Then, however, another bottle arrives. Someone orders dessert drinks. Suddenly, what seemed like sophisticated socializing turns into next-morning negotiations with your nervous system.And that raises the obvious question:What actually causes a hangover?More importantly, why do so many supposed “cures” fail so spectacularly?First, Alcohol Is Not Just “Dehydration”Many people think a hangover is simply dehydration.Certainly, dehydration matters. Alcohol suppresses vasopressin, the hormone that helps your kidneys conserve water. As a result, you urinate more frequently. Consequently, you lose fluid and electrolytes.However, dehydration is only part of the story.In fact, hangovers are far more complicated.Alcohol irritates the stomach lining. Additionally, it disrupts blood sugar regulation. Furthermore, it interferes with inflammatory pathways, sleep architecture, hormone signaling, and neurotransmitters involved in mood and alertness.So while dehydration contributes to the misery, it does not fully explain why you feel like a Victorian ghost haunting your own apartment.Moreover, alcohol affects sleep in a particularly cruel way.It helps many people fall asleep quickly. However, it fragments restorative sleep later in the night. Therefore, you may technically be unconscious for eight hours while still waking up exhausted.You passed out.You did not recover.Then There’s Acetaldehyde — But It’s Not the Whole StorySocial media wellness culture loves one word:Acetaldehyde.This is the toxic metabolite created when your liver breaks down alcohol. And yes, acetaldehyde contributes to flushing, nausea, headache, and inflammation.Nevertheless, modern marketing often exaggerates its role because it creates a simple story.“If acetaldehyde is bad, then a supplement that lowers acetaldehyde must solve hangovers.”Unfortunately, biology is rarely that convenient.Hangovers are not caused by one molecule acting alone. Instead, they are the result of multiple overlapping physiologic stresses happening simultaneously.In other words, there is no single “off switch.”And that is exactly where the supplement industry enters the picture.The Rise of the “Hangover Cure” IndustryOver the last several years, social media has become flooded with products promising recovery, detoxification, or “support” for drinking.For example:Cheers RestoreZBioticsMyrklH-PROOFDHM DetoxDose for LiverFurthermore, many of these products use similar language:“supports liver health,”“helps metabolize alcohol,”“promotes recovery,”or “supports detoxification.”Notice the wording carefully.Most companies avoid explicitly claiming to “cure” hangovers because proving that scientifically would require strong clinical evidence.And, unfortunately for marketing departments everywhere, that evidence largely does not exist.So Do These Products Work?The honest answer is:Probably not very well.Now, to be fair, some ingredients are biologically plausible. For instance, DHM — dihydromyricetin — has shown interesting effects in animal studies involving alcohol metabolism and GABA signaling.Likewise, some probiotics may influence acetaldehyde metabolism in the gut. Meanwhile, antioxidants and electrolytes may help support recovery in limited ways.However, plausible does not mean proven.That distinction matters enormously.Most studies on hangover products are:small,poorly standardized,company-funded,or focused on surrogate laboratory markers rather than meaningful real-world outcomes.Consequently, the evidence remains weak.And that is why most medical reviews conclude the same thing:there is no strong evidence that popular hangover cures reliably work as advertised.Meanwhile, IV Clinics Are Mostly Selling Expensive Salt WaterPerhaps nothing captures modern wellness culture better than the rise of the “hangover IV.”Now, certainly, IV fluids can help with dehydration. Additionally, anti-nausea medications may temporarily improve symptoms.Nevertheless, many hangover IV clinics market themselves almost like detox spas.And that language becomes misleading very quickly.Your liver already detoxifies alcohol. In fact, that is literally its job.Moreover, your liver clears alcohol at a relatively fixed rate. Therefore, no vitamin infusion dramatically speeds the process.So while IV hydration may help some symptoms, it does not reverse toxicology.It is mostly expensive supportive care with mood lighting.What Actually Helps?Unfortunately, the most effective hangover treatments are also the least exciting.First, hydration genuinely matters.Water, electrolyte drinks, broth, and even fruit juice can help restore fluid balance and blood sugar.Second, bland foods often help settle the stomach.For example:toast,rice,crackers,eggs,or soup.Interestingly, pho may actually be one of the better hangover foods because it combines fluids, sodium, carbohydrates, and easy digestion.Third, sleep matters enormously.Alcohol damages sleep quality. Therefore, recovery sleep becomes critical afterward.Meanwhile, pain relievers should be used carefully.Ibuprofen or aspirin may help with headaches. However, they can worsen stomach irritation.And acetaminophen deserves special caution.Alcohol stresses liver metabolism. Acetaminophen also relies heavily on liver pathways. Consequently, combining large amounts of alcohol with Tylenol can become dangerous.Some Supplements May Help a LittleNow this is where nuance matters.A few supplements do show modest signals in limited studies.For example:Prickly pear extract has shown some reduction in inflammatory hangover symptoms.Red ginseng has demonstrated modest improvement in some small trials.Siberian ginseng and combination antioxidant products have shown scattered positive findings.However, none of these products “cures” hangovers.Furthermore, the studies are small and inconsistent.Most importantly, they are not permission slips for binge drinking.The Part Nobody Likes HearingHere is the uncomfortable reality.Even intermittent heavy drinking may have long-term consequences.Many people believe occasional binge drinking is harmless because they are still functioning professionally and socially.However, alcohol remains neurotoxic.Repeated episodes of heavy alcohol exposure are associated with changes in cognition, mood regulation, sleep quality, memory, and brain structure over time.And importantly, aging reduces the brain’s ability to compensate for injury.Therefore, the “weekend warrior” approach to alcohol may not be as biologically benign as people hope.Meanwhile, our culture often treats alcohol very differently from other health risks.People obsess over processed foods, seed oils, artificial dyes, or gluten.Yet somehow, repeated alcohol poisoning became normalized in adulthood with appetizers.That contradiction is worth thinking about.So What Is the Best Prevention?Unfortunately, prevention is boring.And yet boring works.Drink less.Drink slower.Eat before drinking.Alternate alcohol with water.Avoid “catch-up drinking.”Prioritize sleep afterward.And, additionally, lower-congener drinks like vodka or gin may produce fewer hangover symptoms than whiskey, bourbon, or brandy.Not because they are healthy.Simply because they contain fewer additional fermentation compounds.Final ThoughtsUltimately, the science of hangovers is less glamorous than the internet wants it to be.There is no miracle cure.There is no magical probiotic that allows unlimited tequila without consequences.There is no gummy that outperforms biology.Instead, a hangover is your body responding to inflammation, dehydration, toxic exposure, disrupted sleep, and metabolic stress.In other words, it is not a vitamin deficiency.It is a receipt.Outside ReadingFor a good evidence-based overview of hangovers and the limited science behind hangover remedies, see the review from the Cleveland Clinic on hangover cures and the National Institute on Alcohol Abuse and Alcoholism (NIAAA) overview of hangovers.

The “Real Food” Protein BarThere may be no phrase in modern nutrition more ridiculous than this:“Real food protein bar.”And yet, somehow, we are expected to nod seriously when someone says it.Recently, internet nutrition personality Paul Saladino introduced what he described as his best “real food” protein bar. While I have nothing personal against the man. I admire the confidence required to sell twelve protein bars for forty-four dollars while talking about ancestral living.Because let’s be honest for a moment.Protein bars are the modern candy bar.They simply come wrapped in better branding, cleaner fonts, and enough wellness language to make people feel virtuous while eating what is essentially an expensive Snickers bar with a podcast sponsorship.Now, before the internet declares me anti-protein-bar, let me clarify something immediately.I actually like Aloha bars.They’re expensive, but they say the right words to me. More importantly, they taste better than most compressed drywall products pretending to be nutritious. At the same time, real life exists, and sometimes convenience matters because airports happen, traffic happens, and long clinic days happen.Still, pretending industrial engineering somehow untouches these foods is a bit like pretending woodland elves handcrafted a Tesla.Breakfast Used to Be a Moral LectureTo understand how we got here, we need cereal, because cereal tells the entire story of modern food in one aisle.The first cereals in America were essentially granolas—dense grain mixtures that required chewing, preparation, and a bit of commitment. While nobody was exactly dreaming about them at night, they solved an important problem because they stored well, traveled well, and provided calories in an expanding industrial society.Then along came John Harvey Kellogg.Now, Kellogg was brilliant, strange, deeply moralistic, and profoundly suspicious of pleasure. He believed rich foods, spicy foods, meat, and almost anything enjoyable stimulated dangerous passions, and among those passions, he was particularly terrified of masturbation, which he viewed as one of the great threats to civilization.So his answer was blandness.Very blandness.Little sugar. Little excitement. Little stimulation.The original breakfast cereal movement was not designed around pleasure.Instead, it was designed around suppression.In many ways, those cereals were crunchy moral discipline.Then the Cereal Aisle Became Las VegasFast forward a hundred years, and the cereal aisle becomes the exact opposite of Kellogg’s vision.Sugar increases dramatically.Crunch becomes engineered.Colors explode across the box.Mascots arrive to recruit children before they can read.Eventually, breakfast stops being a health intervention and slowly transforms into dessert with vitamins sprinkled on top.And importantly, none of this happened because someone woke up wanting to destroy public health.That’s the part people often misunderstand.Food Engineering Solved Real ProblemsBefore obesity became the dominant nutritional problem, the real challenge facing humanity was hunger.For most of history, people worried about:starvationfood spoilagecrop failurestransportationand simple calorie availabilityModern food engineering changed that reality.Shelf-stable foods mattered.Affordable calories mattered.Transportation mattered.Refrigeration mattered.And honestly, millions upon millions of lives have been improved because of those advances.It is very easy for people with stocked refrigerators and grocery delivery apps to romanticize the past, but the past involved a tremendous amount of malnutrition, uncertainty, and hunger.So modern food systems were not evil.They were revolutionary.The Problem ChangedHowever, in solving one problem, we slowly created another.Because once calories became:cheapportablestableand endlessly available…the challenge was no longer finding enough food.The challenge became stopping.And this is where modern biology collides with the modern grocery aisle.Our brains evolved in environments where calorie-dense food was rare and valuable. Suddenly, within just a few generations, we found ourselves surrounded by foods engineered to be affordable, repeatable, and highly rewarding.That mismatch matters.Extrusion Changed EverythingMost people have never heard the word extrusion, even though it may be one of the most important food technologies in modern life.The process is simple.Take starches, grains, or protein powders.Apply heat and pressure.Force them through machinery.Suddenly, you have:cerealcrackerscheese puffsprotein snacksbreakfast barsAnd here is the important part: extrusion changes texture, and texture changes satiety.When food crunches perfectly, dissolves quickly, and slides down effortlessly, people consume more of it before fullness has time to register.That is not a conspiracy.It is simply biology interacting with engineering.The Grocery Store Became Natural SelectionFood companies did not necessarily set out to create hyper-palatable foods.Instead, they followed what sold.And what sold was what people returned to again and again.So over time, the grocery aisle became a form of natural selection.Products survived because they triggered pleasure effectively.Foods that didn’t simply disappear.And I will confidently say something controversial:Reese's sells better than Brussels sprouts.I will die on that hill.Now, yes, Brussels sprouts can be delicious roasted with olive oil and balsamic, and somewhere at this exact moment, a chef in Brooklyn is shaving them raw onto handmade pottery while explaining their emotional complexity.Still, Reese’s triggers something primal.Sweetness.Fat.Salt.Texture.And your brain immediately says:“Yes. More of that.”Food Is EmotionalFood is not just chemistry.Food is memory.It is also culture.What we eat is comfort.For some people, comfort food is a tamale. For others, it’s lefse. Meanwhile, many people find that comfort in peanut butter cups or a Dove Bar.The grocery aisle evolved around those emotional realities much faster than human biology evolved to manage them.And that matters, because modern eating is not simply about willpower.It is about environment.Cooking Changes the ExperienceNow compare all that to actual cooking.Not content-creator cooking.Real cooking.A stew simmering slowly.A roast chicken filling the kitchen with aroma.A tagine building layers of flavor from preserved lemon, apricots, and warm Moroccan spices.That kind of food slows you down.You smell it before you eat it.You notice texture.You experience layers of flavor.And interestingly enough, you often need less of it to feel satisfied.That is one of the great ironies of modern eating.As food became more engineered for efficiency, it often became less satisfying experientially.The Wellness FantasyThere is another uncomfortable reality that nobody on wellness Instagram likes to admit.In order to feed a hungry planet, we cannot all live on pasture-raised beef, farm-fresh eggs gathered from cheerful backyard chickens, and organic kale harvested by a local poet-farmer wearing linen.That is not a food system.That is a lifestyle catalog.The modern world has eight billion people.Food has to:travelsurvive droughtssurvive warssurvive supply chain failuresand feed cities that no longer produce their own caloriesEngineered foods are not going away.Nor should they.Yes, Even on MarsWhen human beings eventually colonize Mars, we are not putting cattle on the rocket ship.Nobody is building a space ranch outside Olympus Mons.Likewise, we are not stocking the moons of Jupiter with artisanal grass-fed herds wandering peacefully beneath methane clouds.Instead, we will use engineered foods and lab-grown proteins, because they will be:efficientreproducibleresource-consciousand eventually taste just as goodThat future is not dystopian.It is practical.The Real Challenge NowThe challenge facing us today is very different from the challenge facing humanity a century ago.We no longer live in a world where most people fear starvation.Instead, we live in a world where many people are simultaneously overfed and undernourished.Calories are abundant.Satiety is not.And that is where medications like GLP-1 are helping many people—including

Let’s Start With What Nobody Tells YouWhen people start a GLP-1, they are told what to avoid. What side effects to expect, and sometimes how much protein they should be eating. While that information has its place, it misses the part that actually changes your day-to-day life. Because what really shifts is not just how much you eat, but also how you experience it.At first, that change can feel subtle, almost easy to miss. Because nothing dramatic happens overnight. Although for me it did. In addition, over the course of a few days and weeks, you begin to notice that foods you used to reach for automatically no longer have the same pull, and simultaneously, foods you barely thought about before start to feel more interesting, more satisfying, and more worth your attention.So instead of asking what you should eat, a better question becomes what you actually want to eat. Because that answer starts to change.The Old Way: Eating Without NoticingBefore this, eating was often fast, automatic, and driven by something that wasn’t quite hunger. Most meals were about filling up rather than tasting anything. Once the plate was in front of you, it didn’t take long for it to disappear.In many cases, food was less about enjoyment and more about reaching that point of fullness where the urge to eat finally quieted. Which meant convenience foods made sense, large portions felt normal, and finishing everything was exactly what you did.As a result, you weren’t really tasting food; you were processing it. And that difference matters more than people realize.Then the Shift BeginsAfter starting a GLP-1, the signal changes. While it doesn’t happen the same way for everyone, it shows up quickly enough that you notice it in small ways. Because you slow down without trying, you pause between bites without thinking, and you stop earlier than you used to.That pause is important because it gives you a moment to notice what you’re eating. Once you notice, you start making choices that feel different from before, not because you are forcing yourself to be disciplined, but because your body is guiding you in a new way.Gradually, eating becomes less about quantity and experience, and that shift changes everything.Lunch: Where Real Life HappensFor most people, lunch is not a carefully planned event, and that’s exactly why it’s a good place to see what actually works.On many days, I keep it simple because simple is reliable. A chicken breast heated up in the morning with a bit of hot sauce does the job without much effort. while a couple of apples and some grapes can carry me through the late morning and early afternoon without feeling like I need a full sit-down meal. Plus, if I am driving, eating slices of apples and grapes keeps me awake.At the same time, I don’t force structure onto it, because grazing a bit throughout the day often fits better than trying to recreate the old idea of a formal lunch, and that flexibility makes things easier rather than harder.On other days, I might grab a sandwich, and while it could be like a triple-decker club. The difference now is not what I order, but how much I eat, because stopping halfway feels natural instead of forced. Whatever is left has a way of disappearing quickly once my son gets home from school.Eating out follows the same pattern, because one or two tacos are usually enough. While fried foods sometimes feel heavier than they used to, grilled or ceviche-style options bring out flavor without that weight, making the experience better without trying to optimize anything.Simple Food Becomes Better FoodAt some point, you realize that simple foods start to feel more satisfying than they used to. And something like a good tuna, mixed with yogurt, lemon, and a bit of mustard, becomes a meal that you actually look forward to. Rather than something you eat because you think you should.Bread becomes optional, not forbidden, and sometimes a bowl or a few crackers is all you need, which removes the sense that meals must follow a certain format.Seasonal fruit fits into that pattern. Because when something tastes good, you eat it, and when it doesn’t, you move on, which is a different mindset from trying to force certain foods into your day.Even something as simple as peanut butter and jelly can feel satisfying again, because the experience of eating it has changed.Hydration Stops Being an AfterthoughtOne thing that becomes more noticeable is how important drinking fluids actually is because when you eat less, you naturally take in less water from food, and that means you have to be more intentional about it.For me, iced tea works because it adds a bit of flavor without adding much else. Making it overnight in a pitcher means it’s ready when I need it, which turns hydration into a habit instead of something I forget about.That small shift makes a bigger difference than most people expect, because feeling off is often just a sign that you need to drink more.Dinner Becomes Something DifferentDinner changes in a way that feels less structured and more creative. Because instead of trying to build a large meal, you start thinking about what would actually be enjoyable.Cooking becomes more interesting, not because you are trying harder, but because you have the space to pay attention. Dishes like salmon, pasta with a well-made sauce, or even something new from a meal kit can feel like something you are exploring rather than something you are consuming.At the same time, there is more room for variety, because you are not relying on volume to feel satisfied, and that allows you to try different things without needing to make them large.Still Paying Attention MattersEven with all these changes, I still track what I eat using Noom. Because awareness doesn’t go away just because the biology works differently. And that habit keeps things grounded without turning it into something rigid.Going out to eat is still part of life, and in many ways, it becomes more enjoyable because you can focus on what you like rather than how much you can eat, and sharing a meal or splitting something becomes a natural part of the experience.Dessert Tells You More Than You ThinkDessert is where you can see the shift.Most of the time, I don’t think about it, and that alone is different, because it used to be automatic.Every now and then, especially when I’m getting close to my next dose, I’ll notice that I want something sweet, and I might have an ice cream bar, and that’s enough.That moment says more than any rule ever could. It shows the drive is lower, not gone, and that you can respond to it without being controlled by it.The Real ChangeWhat has changed is not complicated, but meaningful.I go for flavor instead of volume.Timing, now I take my time tasting instead of rushing.Choosing where and what to eat depends on whether it is worth it, not whether it is popular or convenient.Food is not the enemy.It never was.Some days, I am simply not interested in dinner, and if lunch was larger, I might just have a protein shake and move on, because eating is no longer something I have to do on a schedule.A Different Way of EatingThis is not a diet. It is not a plan. It is not about perfection.Instead, it is about eating in a way that matches how your body now works, which means paying attention, making choices, and allowing yourself to enjoy food without relying on it for everything else.Before, I filled my mouth before thinking, and swallowing before experiencing.Now, I taste.

It’s not a straight line. It’s not a diet. And it’s definitely not what you expect.I started my journey on a GLP-1 in October 2024. While my doctor did what good doctors do—he gave me the warnings, the precautions, the usual advice about what to avoid and watch for—I quickly realized something was missing. No one really told me what it would feel like. More importantly, no one explained that this first month doesn’t unfold in one neat, predictable way, but instead moves along several paths depending on the person, their biology, their habits, and frankly, a bit of luck.So, as I’ve watched friends, patients, and many people start this same journey, I’ve come to understand that the first month is less about weight loss, and far more about discovery, adjustment, and occasionally confusion. While people expect something simple, they get instead of variation, and that variation can make them think something is wrong when everything is going exactly as it should.The Myth of the Straight LineMost people begin this process believing they will take the medication, lose their appetite, and watch the scale steadily drop. While that story is appealing, it simply isn’t how the body works, because biology rarely follows a script, and in this case, the first month is more like learning a new language than following a plan.What becomes clear quickly is that people fall into different patterns. While none of these patterns are right or wrong, understanding which one you are in can make all the difference in how you interpret the experience.The Three Paths of the First MonthSome people, myself included, are what we call hyper responders. Although we don’t fully understand why this happens, the effect can be dramatic. Within about twelve hours of my first dose, something shifted in a way I did not expect, as the constant chatter in my head about food—what we used to call head hunger—simply disappeared, and I didn’t even know it had been there until it was gone.During that first month, I lost twelve pounds, and while most of that was water and glycogen with some fat mixed in, the real change was not on the scale, but in my appetite. This dropped so noticeably that I found myself stretching out the time between doses. Interestingly enough, my obstructive sleep apnea improved, which was not something I had anticipated, but certainly appreciated.At the same time, my doctor had warned me to drink more fluids, and that advice was critical, because much of the water we normally get comes from food, and when food intake drops, hydration must be a conscious effort. So I adjusted by adding a protein shake in the morning and increasing my iced tea throughout the day, and that simple change made a meaningful difference in how I felt. You can find my recipes for protein shakes on the recipe section of my site, terrysimpson.com.The Normal RespondersOn the other hand, most people do not have that kind of immediate response, and instead they fall into what I would call the normal responder group, where the changes are subtle at first, and because they are subtle, they are easy to miss, which leads many to think the medication isn’t working, especially when they compare themselves to others who seem to be losing weight quickly.What they don’t notice, however, is that they are snacking less, leaving a bit of food on their plate, and skipping that second helping more often than before, and while these changes may seem small, they add up over time, because when someone tells me they only lost four pounds in a month, I translate that into nearly fifty pounds in a year, and suddenly the perspective shifts from disappointment to possibility, because that is a sustainable path.The Strugglers - they need helpThen there is the third group, the strugglers, and these are the people who feel the effects right away but not in a pleasant way, because nausea, delayed gastric emptying, and an uncomfortable sense of fullness can make the experience feel miserable rather than helpful, and in these cases, intervention becomes important, since without adjustment, these individuals can run into real problems.What helps here is not complicated, but it does require attention, because smaller meals, avoiding fatty foods early on, focusing on liquids, and most importantly, never eating until full can turn things around, and more often than not, dehydration is the hidden issue, which is why something as simple as popsicles made from electrolyte solutions can provide both relief and hydration, and the key word for this group, more than anything else, is pacing.Food Noise and the Silence That FollowsBefore GLP-1 medications, we often described something called head hunger, which is that feeling of wanting food even when the body does not need it. The distinction between real hunger and head hunger is easier to understand than most people think. If you are truly hungry, something simple like a meatball will satisfy you, whereas if it is head hunger, you will find yourself reaching for cookies, candy, or snacks high in calories but low in nutrition.This is what we now call food noise, and for many people, it is constant, although they may not recognize it until it disappears, which is exactly what happens on a GLP-1, and that disappearance can feel both liberating and unfamiliar at the same time.I can always tell when mine starts to come back, and recently, I delayed my dose for a few days because I was celebrating my wife’s birthday, and the next day, before I resumed the medication, I found myself buying multiple boxes of ice cream bars, not because I needed them but because that voice had returned, quietly suggesting that I might want them, and once I took the dose again, that same voice faded, leaving me to wonder why I had bought them in the first place.That voice is persistent, not loud but steady, and it doesn’t shout like an alarm but instead calls like a siren from an old story, inviting you toward something you don’t need but think you want, and turning that down is one of the most profound changes this medication brings.What Changes Over the First Few WeeksAs the first month unfolds, the early days are often inconsistent because appetite may vary from one day to the next, and while some meals feel normal, others feel different, and this unpredictability can make people uneasy, especially if they expect immediate stability.Gradually, however, things begin to settle, and by the third or fourth week, satiety arrives earlier, meals become smaller without effort, and foods that once felt irresistible lose some of their pull, not because they are forbidden but because they are no longer as compelling.At that point, behavior starts to align with biology, and instead of forcing discipline, people find themselves responding to signals that finally make sense.What Actually Helps in the First MonthSuccess in the first month comes down to a few consistent themes, and while none of them are complicated, they are easy to overlook, because smaller meals tend to feel better, slower eating becomes natural, hydration proves essential, and real food often becomes more appealing, all while the pressure to eat disappears.In addition, forcing food when you are not hungry rarely ends well, and learning to stop earlier than you used to becomes one of the most important adjustments you can make.The Emotional Shift No One Talks AboutOne of the most surprising aspects of this process is not physical but emotional, because when the constant thinking about food quiets down, there is a sense of relief, yet at the same time, there can be a feeling of disorientation, as if something familiar has gone missing.For many people, food fills more than just hunger because it fills time, emotion, and habit, and when that changes, there is space to be filled in new ways, which can feel uncomfortable at first but ultimately becomes an opportunity.A Different Way to Think About the First MonthThe first month on a GLP-1 is not about rapid weight loss, and it is not about perfection, and it certainly is not about willpower, because what it really represents is a shift in how the body communicates and how the mind responds.Instead of fighting hunger, you begin to understand it, and instead of chasing food, you begin to choose it, and in that process, something changes that goes far beyond the number on a scale.One Final ThoughtIf you are considering this journey, it is worth finding a board-certified obesity specialist because they have the training and experience to guide you through these changes in a way that most physicians simply do not, and that guidance can make the difference between frustration and success.And as for that first month, it is less about what you lose and more about what you learn, because what you are really discovering is what it feels like to not be controlled by food for the first time in a very long time.

Why GLP-1 Made Me Love Food More—Not LessFrom beetroot pasta to backyard salsa, this wasn’t about eating less. It was about finally tasting more.I want to tell you about two people on a GLP-1.First, there’s me.I’ve been on a maintenance dose—7.5 mg of Zepbound—for a while now. And recently, I went to an incredible Michelin-star restaurant. Now, at one point during that meal, I said something that surprised even me.The beetroot pasta was one of the best dishes I had ever tasted.Now, let’s pause there—because this matters.I don’t like beets.In fact, I’ve always said I hate beets.And yet, there I was, enjoying beetroot pasta.So what changed?Well, not my opinion of beets.But absolutely my appreciation of flavor.Then, Something Unexpected HappenedDuring that same trip to Italy, I had one remarkable meal after another. For example, I ate at Ristorante Aroma, right next to the Colosseum. Then, I found a small, unforgettable place tucked away in Venice.Now, let me be clear—this is not a humble brag.Yes, the restaurants were fantastic. Yes, the trip was memorable.However, I’ve been to Europe before.And yet, this time was different.Because this time, I didn’t just eat the food.Instead, I tasted it.Moreover, I slowed down.In addition, I noticed the precision.And perhaps most importantly, I appreciated the flavors.Before, I think I liked good food.Now, I actually understand it.But Then There’s My FriendOn the other hand, there’s my friend.He’s also on a GLP-1. In fact, he weighs a bit less than I do. However, he told me something that stopped me in my tracks.“I don’t enjoy food anymore.”Now, that’s not discipline.And it’s certainly not success.Instead, that’s anhedonia.In his case, the dose was too high. As a result, appetite didn’t just quiet down—it disappeared. Furthermore, dehydration crept in. And on top of that, nutrition slipped just a bit.Consequently, food wasn’t enjoyable anymore.It was just… there.So, we made a small adjustment.We lowered the dose.Now yes, that can feel frightening. Naturally, people worry:“If I lower it, I’ll gain the weight back.”However, that didn’t happen.Instead, what came back was enjoyment.And Then There’s the Protein Bar ProblemNow, let’s shift gears—because this is where things get interesting.Every now and then, you need a snack. That’s normal. That’s life.However, when it comes to protein bars, I have to be honest.Most of them don’t taste like food.Instead, they taste like wet sawdust. Or, perhaps more accurately, dry particle board with a chocolate label slapped on it.Yes, they try. They add peanut butter flavor. They add cocoa.But still, the texture is off. The taste is off. And ultimately, your brain knows it.Now, to be fair, I do like some Aloha bars. They’re better than most.But even then…Recently, I skipped the bar.Instead, I had something entirely different:Tocino.A few bites.That’s all.And yet, those few bites delivered something protein bars rarely do:Flavor.Real flavor.Not engineered. Not simulated. Not “chocolate-adjacent.”Actual spices. Actual cooking. Actual food.And, frankly, it was fantastic.Meanwhile… the $32 Steak SnackOf course, I also tried one of those dried carnivore steak snacks.Thirty-two dollars.And honestly?Awful.Dry. Chewy. Completely joyless.At that point, you’re not eating—you’re making a statement to someone online.Instead, you’d be far better off flying to Spain and enjoying someJamón Ibérico.Because then, at least, you get flavor. And culture. And an experience.Now, Let’s Talk About BreakfastMost mornings, I have a smoothie.And it works.Specifically, I use oat milk, protein powder—this week I’m trying Ora pea protein—along with cocoa, coffee, blueberries, and a bit of banana.It’s quick. It’s consistent. And importantly, it fits into life.Especially when you’re stuck in California traffic.In fact, traffic moves so slowly here that I didn’t even have to get out of the car to move a snail off the road—he made it across before I got there.So yes, smoothies make sense.However, When I’m Home…Things change.Now, there’s nothing wrong with a bowl of Cinnamon Chex.It’s fine.But often, I want something more.So instead, I make:Poached eggsA splash of Louisiana Hot SaucePico de galloFresh tortillasBeansAnd, of course, real salsa.Not the jarred kind.Instead, the kind that takes an afternoon to make. The kind that improves overnight. The kind your neighbor brings over—and yes, you briefly consider paying her to keep making it, before realizing that might get a little awkward.So What’s Going On Here?At this point, you might think this is about “good food” versus “bad food.”But it’s not.Instead, it’s about awareness.Because much of what we eat today comes from a system designed for convenience.For example, extrusion—the process that creates cereals, protein bars, and many snack foods—makes food:Shelf-stableAffordableEasy to eatAnd importantly, easy to overeat.Because when food requires no effort…You don’t stop.But Here’s the Key PointThere is nothing wrong with food.Not with cereal. Not with protein bars. Not with convenience.However, GLP-1 changes something fundamental.It changes you.Specifically, it allows you—sometimes even forces you—to slow down.And because of that, you begin to:Notice flavorTake your timeActually enjoy what you eatBefore, I was filling my mouth before thinking.And I was swallowing before experiencing.Now?I taste.And That Changes EverythingBecause now, I can enjoy:The precision of fine diningThe bold flavors of the PhilippinesThe chunky salsa from my neighbor’s kitchenAnd suddenly, eating less becomes… more.More experience.More appreciation.More enjoyment.One Last ThingThere’s nothing wrong with Cinnamon Chex.But it’s not a morning habit anymore.Instead, it’s an every-now-and-then food.It’s interesting.But it’s not better.Because once you start tasting food the way it’s meant to be tasted…You don’t go back to eating it the way you used to.

The word “peptide” is doing too much workLet’s start with the simplest truth.A peptide is just a chain of amino acids—like pearls on a necklace. That’s it. Nothing mystical. Nothing magical.However, structure matters. Sequence matters. Biology cares deeply about both.Because of that, some peptides are extraordinarily powerful. Others are biologically interesting. And a growing number are simply… marketed.That last category is where things get messy.Before the hype, there was a miracleNow rewind to a hospital ward in Toronto in the early 1920s.Children with diabetes were dying. Not slowly improving. Not plateauing. Dying.Then Frederick Banting and Charles Best walked in with something crude and experimental.Insulin.They injected it.The children woke up.Not metaphorically. Not in a graph. They woke up. Families watched death reverse in real time.That is what a peptide can do when it actually works.Then came the desert and the lizardFast forward a few decades.Out in the Southwest—near where I started my first job as a bariatric surgeon in Phoenix—lives the Gila monster. Not exactly a creature you expect to change medicine.Yet inside its venom was a peptide that led, eventually, to drugs like:SemaglutideThat discovery didn’t go straight to Instagram.Instead, it went through:receptor biologypharmacologyclinical trialsoutcomes researchAnd the results were real:lower blood sugarmeaningful weight lossreduced cardiovascular riskSo yes, peptides can be extraordinary.But only when the science is finished.And then we lost the plotNow, enter the modern peptide market.Suddenly, everything is a peptide. Everything promises:healingrecoveryfat lossanti-agingYou’ve seen the names:BPC-157TB-500CJC-1295IpamorelinMOTS-cAOD-9604Meanwhile, they are sold in places that should make you pause immediately.Gyms.Wellness clinics.Online “research chemical” shops.Rarely, if ever, through the same channels as actual medicine.BPC-157: the peptide that does everything… on paperStart with the most famous one.BPC-157 is marketed as a cure-all:tendon healinggut repairanti-inflammatoryaccelerated recoveryThe claims are sweeping. The confidence is impressive.But then you look at the evidence.Animal studies? Yes.Human randomized trials? No.Long-term safety? Also no.That gap matters.Because when something claims to stimulate healing broadly, it raises an uncomfortable question:What else might it stimulate?The answer, at this point, is simple.We don’t know.TB-500: recovery without receiptsNext comes TB-500.It is sold as a recovery peptide. It promises faster healing and improved flexibility.The biology is plausible. The mechanism sounds reasonable.Yet human evidence for those claims is lacking.Even so, it thrives in:bodybuilding circlesperformance clinicsonline forumsIn other words, environments where anecdote travels faster than data.Hormone peptides: changing numbers vs. changing outcomesNow we get to the hormone crowd.CJC-1295 and Ipamorelin are sold as a stack. They stimulate growth hormone release.That part is real.What comes next is not.Because increasing a hormone level is not the same as improving health.We do not have strong evidence for:long-term outcomessafety over yearsmeaningful clinical benefitsStill, they are marketed as anti-aging therapies.That leap—from signal to certainty—is where the trouble begins.Melanotan II: the one that proves the ruleMelanotan II is different.It actually does something.It increases pigmentation. It affects melanocortin receptors.And with that comes:nauseablood pressure changesmole darkeningdocumented toxicitySo here is the lesson.When a peptide truly works, you don’t get silence. You get side effects.The absence of side effects in marketing should never reassure you.It should make you suspicious.AOD-9604 and MOTS-c: the fantasy layerAt the far end of the spectrum are peptides like AOD-9604 and MOTS-c.They promise:targeted fat lossexercise-like metabolic effectslongevityThe evidence?Mostly cells and animals.Yet they are already being sold, injected, and promoted.At this point, we are not even pretending to wait for human data.Where these actually come fromNow let’s talk about the vial.Because this is where things shift from questionable to concerning.Many of these peptides are:manufactured overseasshipped in bulkrepackagedrelabeledThey are often sold as:“research chemicals”“wellness therapies”Independent testing has found:incorrect dosingcontaminationinconsistent puritySo when someone says they are taking a specific peptide, the real answer is uncertain.They hope they are.Why this is suddenly in the newsRecently, Robert F. Kennedy Jr. has pushed to expand access to peptides restricted by the FDA.The argument is framed as freedom.The FDA’s concern is simpler:lack of safety datarisk of contaminationunknown long-term effectsIn other words, we do not yet know enough to call these safe.That is not obstruction.That is the job.GLP-1: the difference data makesNow compare all of that to GLP-1 drugs.They don’t just sound scientific.They are scientific.They:improve blood sugarreduce weightlower cardiovascular riskMost importantly, they do this consistently, predictably, and measurably.That is what happens when research goes the distance.The bottom linePeptides are not the problem.Peptides gave us insulin.Peptides gave us GLP-1.At their best, they are among the most elegant tools in medicine.But the current peptide market is not built on finished science.Instead, it is built on possibility, dressed up as certainty.And that difference matters.Because the gap between “interesting biology” and “safe, effective therapy” is where patients get hurt.Final thoughtThe difference between a child waking up in a Toronto hospital…and a vial purchased online…is not the molecule.It is the evidence.

The Chorus of “Just Eat Less”Spend a few minutes on social media, and you will hear it. On Bill Maher's podcast the other day, I heard it. Two people who know less about GLP-1 drugs than almost anyone, opining about how GLP-1s are horrific.Bill Maher says, “Just eat less.”Jillian Michaels warns that GLP-1 medications are dangerous. Did she even graduate from college?Meanwhile, a rotating cast of gym bros, coaches, and influencers insists that anyone using these medications is taking the easy way out.At first glance, these seem like different voices. A comedian, a fitness personality, a group of online trainers.However, they are all saying the same thing.If you are overweight, this is your fault.If you need help, you are weak.If you use medication, you are cheating.That message travels well. It is simple. It fits into a tweet. It sounds like common sense. Science shows us that fat shaming doesn't work (reference).It is also wrong.Who Is Doing the Shaming—and WhyThe fitness industry has something to lose here, and that part is easy to understand. Entire businesses are built on the idea that weight loss is a matter of discipline. Follow the plan, buy the program, track the macros, and success will follow. If it doesn’t, the explanation is built in.You didn’t try hard enough.However, the criticism does not stop there.When someone like Bill Maher reduces obesity to “just eat less,” it is not about selling a diet plan. Instead, it reflects something else entirely. A kind of cultural impatience with complexity. A belief that if a problem can be described simply, it must also be solved simply.And when that belief meets a condition like obesity, the result is dismissal.If I don’t struggle with this, then it must not be real.If you do struggle, then you must be doing something wrong.That is not analysis.That is a failure of imagination.The Problem with Simple AnswersMedicine has a long history of being wrong in simple ways.We once believed ulcers were caused by stress alone. Then came Helicobacter pylori and antibiotic treatment. We once thought hypertension was simply a matter of salt intake and personality. Then we developed therapies that addressed the underlying physiology.Obesity has followed a similar path, except we have been slower to let go of the old explanation.“Eat less, move more” is not incorrect.It is incomplete.Because it ignores the system that determines how much you want to eat, how often you think about food, and how your body responds when you try to lose weight.The Part I Didn’t AdmitFor years, I saw the damage this thinking caused.I ran support groups for patients struggling with weight. I watched them come in carrying not just pounds, but shame. They believed they were weak, that they lacked discipline, that something about them was broken.We worked to change that.We talked about biology. About appetite regulation. About how the body defends weight. We tried to replace blame with understanding.And yet, I quietly held myself to a different standard.I didn’t blame my patients.I blamed myself.The Surgeon Who Thought He Could Outwork BiologyIf anyone should be able to power through something, it is a surgeon. That is the job. Endure long hours. Stay focused. Push through fatigue. Delay gratification.So I assumed I could do the same with weight.I tried diets. I cleaned things up. I ate vegetables, cut back on certain foods, and experimented with structure. And like many people, I saw results.At first.Weight loss is not the mystery.Weight maintenance is.Because over time, the same thing happened again and again. The body adapted. Hunger increased. Energy dipped. The system pushed back.And eventually, the weight returned.What the Data Shows (and Why It Matters)When you look beyond personal stories and examine long-term studies, the pattern becomes clear.In the Diabetes Prevention Program, participants lost weight early, then gradually regained some of it. In the Look AHEAD trial, an intensive lifestyle intervention produced initial success, but the gap narrowed over time.Observational data suggest that only a small percentage of people—often cited around 3 to 5 percent—maintain significant weight loss at five years.That number should change the conversation.Because it tells us this is not a widespread failure of discipline.It is a predictable outcome of a biological system.The Loop We Keep IgnoringWeight gain does not happen in isolation. It is part of a loop.Sleep worsens, which increases appetite. Movement becomes uncomfortable, so activity declines. Food becomes more rewarding, not less, because it offers relief.Then intake increases.Then the cycle repeats.And yet, into that loop, we continue to insert the same advice.Try harder.What Finally ChangedFor years, I thought I just needed to try harder myself.I was wrong.Today, I am down fifty pounds.Not because I discovered a better diet, but because something changed in the system itself.I started a GLP-1–based medication.The effect was immediate in ways I did not expect. My sleep improved. My snoring stopped. That alone changed my appetite and energy. Then something else happened.The noise went away.That constant pull toward food, the background awareness that shapes decisions throughout the day, quieted.From there, everything else followed.I began moving more. I returned to yoga, not out of obligation, but because it felt good. Because my body allowed it.This was not about replacing lifestyle.It was about finally being able to live it.What the Critics MissWhen critics say this is the “easy way out,” they misunderstand what is happening.There was nothing easy about fighting biology for years.What these medications do is change the biology so that effort becomes effective.That is not cheating.That is treatment.The Future of Coaching (and Who Will Adapt)The fitness world is not going away.However, it is going to change.The coaches who succeed will not be the ones shaming people for using medication. Instead, they will be the ones who understand how to work with it. They will help people build muscle, improve movement, and develop sustainable eating patterns once appetite is regulated.Mediterranean and DASH-style diets still matter. They remain among the best-supported dietary patterns for long-term health. What changes is the ability to follow them.When the biology shifts, adherence becomes possible.Eating Without FearOne of the most striking changes is how food feels.You no longer need to treat eating as a constant negotiation. You can eat real food. Greek yogurt, eggs, vegetables, and fruit.You can enjoy it.You can eat a peach without worrying about whether you have broken a rule.That is what happens when the noise quiets.Where I Was Wrong—and What Comes NextFor a long time, I believed that effort alone would solve this.I was wrong.Not because effort doesn’t matter, but because effort without the right biology is not enough.Science moves forward by showing us where we were incomplete. In this case, we were incomplete in how we understood obesity.Now we are beginning to correct that.And as we do, the conversation should change.Less blame.More understanding.Less shame.More treatment.Because this was never about character.It was always about biology.

Menopause, Hunger, and the Brain: Why It Feels DifferentMenopause changes more than temperature control. It reshapes how the brain handles hunger, fullness, and the quiet signals that guide eating. As a result, many women notice something unsettling. The same meals no longer satisfy. Hunger arrives sooner. Food feels louder.For years, we blamed metabolism. We told women their bodies were simply slowing down. While that explanation sounds scientific, it misses the most important part of the story.The brain has changed.A Pattern You Can’t IgnoreDuring my years performing weight loss surgery, about 80 percent of my patients were women. Over time, one pattern became impossible to overlook. When menopause or even perimenopause began, weight gain often followed.Some women had struggled with weight for years. Others had never given it much thought. Yet both groups described the same shift. They weren’t necessarily eating more. Instead, they felt hungrier, less satisfied, and more aware of food throughout the day.Meanwhile, the advice they received rarely evolved. Eat less. Move more. Try harder.However, that advice assumes the system regulating hunger still works the same way. In menopause, it doesn’t.Estrogen and the Appetite Control CenterTo understand what’s happening, we need to look at the hypothalamus. This small but powerful region of the brain regulates appetite, energy balance, and hormonal signaling. Under normal conditions, estrogen helps keep this system stable.Specifically, estrogen supports satiety signals and keeps hunger signals in check. In simple terms, it helps your brain recognize when you’ve had enough.As estrogen declines, that balance shifts. Hunger signals grow stronger. Fullness signals become less reliable. Consequently, the internal experience of eating begins to change.This shift explains why women often say, “I feel different around food,” even before their diet changes.Why Hunger Changes FirstInterestingly, appetite changes often appear before measurable increases in calorie intake. Women report thinking about food more often, feeling less satisfied after meals, and noticing hunger earlier in the day.At first glance, nothing looks different from the outside. Yet internally, the system has already shifted.Because of that, traditional advice falls short. Telling someone to eat less without addressing the change in signaling is like adjusting the thermostat while ignoring the wiring.More Than MetabolismAlthough metabolism does change with age, it does not fully explain the experience of menopause-related hunger. A slower metabolic rate might affect how calories are used, but it doesn’t explain why appetite feels louder or less controlled.Instead, the better explanation lies in the brain. The hypothalamus responds differently when estrogen levels fall. As a result, the signals that guide eating become less precise.In other words, this isn’t just about calories in and calories out. It’s about how the body decides when to eat—and when to stop.The Part We Should Have Addressed SoonerFor decades, menopause care focused on symptoms like hot flashes and bone health. Meanwhile, changes in appetite and weight were often attributed to lifestyle or willpower.Unfortunately, that approach overlooked a key fact. Estrogen plays a direct role in appetite regulation.Because of that, many women were told to push harder when their biology had already shifted. That message wasn’t just incomplete—it was unfair.Estrogen Replacement: A Broader RoleWhen clinicians discuss estrogen replacement, they often focus on symptom relief. However, estrogen also affects brain signaling related to hunger and satiety.In the right patient, hormone therapy may help restore some of that balance. It can improve how the brain responds to fullness and reduce the intensity of hunger signals.Importantly, hormone therapy does not inherently cause weight gain. That belief has persisted longer than the evidence supports.Still, therapy isn’t for everyone. Each patient requires an individualized discussion that considers risks, benefits, and goals.A New Layer: GLP-1 and Appetite ControlMore recently, GLP-1 receptor agonists have added another dimension to this conversation. These medications act on the same appetite centers in the brain, strengthening satiety and quieting hunger.Interestingly, estrogen appears to enhance the effectiveness of GLP-1 signaling. Therefore, menopause may not only reduce estrogen levels—it may also decrease the brain’s responsiveness to satiety cues.This interaction helps explain why some women experience such a dramatic shift in appetite during midlife.What Actually HelpsOnce you understand the biology, the approach changes.Rather than focusing solely on restriction, the goal becomes supporting satiety. Meals should include enough protein, fiber, and volume to sustain fullness. Additionally, sleep deserves attention, as poor sleep amplifies hunger signals. Medication reviews also matter, since some drugs can contribute to weight gain.For some women, hormone therapy or GLP-1 medications may play a role. For others, dietary structure and lifestyle adjustments provide meaningful improvement.In every case, the strategy should match the physiology.A Better Way ForwardMenopause is not a failure of discipline. It is a shift in how the brain regulates hunger.Once that shift is acknowledged, the conversation becomes more productive. Women can stop blaming themselves and start working with their biology.Ultimately, the goal isn’t to fight hunger. It’s to understand it.Final ThoughtMenopause doesn’t break the system—it changes the signal.And once you understand the signal, you can respond with clarity instead of frustration.Estrogen as a Key Regulator of Energy Homeostasis and Metabolic Health.Biomedicine & Pharmacotherapy = Biomedecine & Pharmacotherapie. 2022.

The Madness of King Henry VIII—and What We Got Wrong About ObesityThe King We ForgotThere is a moment in history that most of us think we understand. King Henry VIII—large, immobile, temperamental—has become almost a caricature of excess. We picture a man who simply ate too much, moved too little, and paid the price. It is a tidy story. Unfortunately, it is also likely the wrong one.Before the 1530s, Henry was something very different. He was athletic, charismatic, and energetic. He hunted, he jousted, he played sports, and he carried himself like the Renaissance ideal—educated, capable, and physically impressive. His armor, still preserved today, tells that story clearly. Narrow waist. Broad chest. Built for motion.The Fall That Changed EverythingThen everything changes.In January of 1536, Henry was thrown from his horse during a jousting match. The horse fell on him. He was reportedly unconscious for hours. Not minutes—hours. Even by modern standards, that is a significant traumatic brain injury.Soon after, in May of that same year, Anne Boleyn was arrested and executed. She was accused not only of adultery but also of witchcraft. That detail matters. Prior to this period, Henry was not known for superstition. He was a rational thinker. Yet suddenly, accusations of witchcraft become part of the story. It is tempting to say this was political theater. It may have been. Still, the timing is difficult to ignore.Meanwhile, his body begins to change.The Story We Told OurselvesAt first, historians explained this in simple terms. He ate more. He exercised less. Calories in, calories out. That explanation sounds neat. It fits what we like to believe. Even so, the math does not hold up.To gain over 200 pounds, you need a massive and sustained excess of calories. A reduction in physical activity alone does not explain that. We measure activity in METS—metabolic equivalents—and even a dramatic drop in activity would not account for that level of weight gain. In other words, you cannot outrun the math.Yet every January, gyms fill with people who are told exactly that. Move more. Try harder. Burn it off. By February, most of those gyms are empty again. If exercise alone solved obesity, we would not still have the problem.The Organ in ChargeSo what did we miss?The answer sits deep in the brain, in a small but powerful structure called the hypothalamus. It regulates hunger, satiety, hormones, and stress. When it works, eating feels normal. You get hungry, you eat, you stop. No drama. No constant thinking.However, when the hypothalamus is disrupted—by injury, disease, or chronic metabolic stress—that quiet system becomes loud. Hunger no longer behaves like a signal. It becomes a drive.This is not theory. Modern medicine has a name for it: acquired hypothalamic obesity. After traumatic brain injury, some patients develop rapid weight gain, persistent hunger, and changes in impulse control. Studies show that nearly half of patients with significant brain injury gain weight over time. The strongest predictor is not inactivity. It is hyperphagia—an abnormal increase in appetite.In simpler terms, the problem is not how much people move. It is what their brain is telling them to do.What Patients Taught MeThat pattern feels familiar if you have ever sat with patients. I have. Years ago, working with former NFL players, we noticed something striking. The players who struggled most with weight often had long histories of concussions. Not all of them gained weight. Yet those who did described the same experience—something they had never felt before.Food noise.Not hunger. Noise. A constant suggestion that does not go away.At first, I understood that as a physician. Later, I understood it as a person.When the World Went QuietAbout twelve hours after my first injection of Zepbound, something changed. The world became quiet. For the first time, I realized how much of my thinking had been shaped by that background noise. It did not disappear dramatically. It simply stopped.Since then, I have lost fifty pounds. More interesting than the weight loss is what happens between doses. As the medication wears off, the noise returns—subtly at first. A thought here. A reminder there. Even my stress levels rise slightly, something I can see on my WHOOP device. Then, a few hours after the next injection, it quiets again.That experience changes how you see patients. It changes how you see history.Looking Back at HenryBecause now, when we look back at Henry, we are not just looking at excess. We are looking at a possible disruption of the system that regulates behavior itself.There are hints of this even in his own time. A French ambassador noted that Henry’s chronic leg pain troubled him often and that he compensated by eating and drinking more. Later reconstructions suggest large meals, heavy in meat, along with substantial alcohol intake. Those numbers are estimates, not precise measurements. Even so, the pattern is clear.Something was driving the behavior.Decline, Not IndulgenceBy the end of his life, Henry could barely move. Mechanical devices were needed to help him stand. He lost close allies, including Thomas Wolsey and Thomas More. His body deteriorated. His mood worsened. This was not simply indulgence. It was decline.What We Can Do NowToday, we have tools that speak directly to that system. GLP-1 medications do not give people discipline. They restore control. Patients do not say they are stronger. They say it is quieter.That distinction matters.Because obesity was never just about calories. It was about signaling and about biology. It was about a system that, once disrupted, can push behavior in ways that are very difficult to resist.The Real LessonSo when we look at Henry VIII, we should be careful before we judge him as a man who simply lacked restraint.We may not know exactly how much he ate.Nevertheless, we know something was driving it.And when we ignore that truth today, we do more than misunderstand the disease.We blame the patient for having it.ReferencesArgente J, Farooqi IS, Chowen JA, Kühnen P, López M, Morselli E, Gan HW, Spoudeas HA, Wabitsch M, Tena-Sempere M.

When Beef Becomes Belief: The Carnivore PriesthoodNutrition debates rarely begin with money. Yet money almost always explains how they spread.That fact explains much of the modern carnivore movement.At first glance, the carnivore diet appears to be a radical nutritional idea: eat beef, organs, and animal fat while avoiding vegetables, grains, legumes, and most fruits. Advocates often present the idea as a return to ancestral eating. According to the story, prehistoric humans thrived on meat, and modern illness appeared only after plants and processed foods entered the menu.However, once you look past the rhetoric, another pattern appears. The carnivore movement did not grow out of decades of clinical research. Instead, it grew out of a very modern ecosystem: social media, podcasts, influencer culture, and supplement companies.And once that ecosystem forms, the incentives become clear.First, someone declares that conventional nutrition science has misled the public. Next, they present a dramatically simple solution. Afterward, they build a community around that solution. Eventually, products appear—supplements, coaching programs, special meat boxes, laboratory panels, and branded lifestyle advice.In other words, the diet becomes the marketing engine.And beef becomes the sacrament.Why Simplicity SellsExtreme diets succeed for a reason. Complexity frustrates people, while simplicity reassures them.“Eat a balanced diet rich in vegetables, whole grains, legumes, fish, and moderate meat” may represent excellent advice supported by decades of research. Unfortunately, that advice does not travel well on social media.By contrast, statements such as “plants are poison” or “fiber is unnecessary” spread rapidly. Bold claims generate engagement. Engagement produces followers. Followers create revenue streams.Consequently, the carnivore diet does not function only as a nutritional recommendation. It functions as a brand.Once someone builds that brand, they must defend it.The Prophets: The Case of the Liver KingEvery belief system eventually develops its prophets, and the carnivore world found one in a man who called himself Liver King.He appeared online with an enormous beard, an even larger physique, and a simple message: modern men had grown weak because they had abandoned the practices of their prehistoric ancestors. According to his message, people should eat raw organs, train like cavemen, reject modern foods, and adopt “ancestral living.”Conveniently, the ancestral lifestyle also included supplements he sold through his company.The marketing proved effective. The image of a muscular barbarian rejecting modern science attracted millions of followers and produced a supplement business worth tens of millions of dollars.Unfortunately, the story collapsed in 2022 when leaked emails revealed the Liver King spent more than $10,000 per month on anabolic steroids and other performance-enhancing drugs. Shortly afterward, he admitted publicly what physicians suspected from the beginning.Raw liver did not build that physique.Pharmacology did.Nevertheless, the episode illustrates the economic logic of the carnivore movement. First comes the doctrine. Then comes the identity. Finally, come the products.The Theologians: Paul SaladinoMovements rarely survive on prophets alone. They also require theologians—people who explain the doctrine with intellectual confidence.Within the carnivore community, one of the most prominent interpreters has been Paul Saladino, a physician originally trained in psychiatry who later rebranded himself as Carnivore MD.For several years, his message remained uncompromising. Plants contained toxins. Vegetables acted as chemical weapons. Humans thrived best on meat, organs, and animal fat. His book The Carnivore Code argued that modern civilization misunderstood nutrition and that health required a return to meat-centered eating.However, the human body eventually entered the conversation.After spending years on a strict carnivore diet, Saladino described several physiological problems: poor sleep, heart palpitations, muscle cramps, and hormonal changes. Consequently, the diet evolved.Fruit appeared. Honey appeared. Raw dairy appeared.Today, the diet carries a new label—an “animal-based diet.” In practice, that means meat accompanied by carbohydrates from fruit and honey.In other words, the diet rediscovered sugar.This pattern appears frequently in nutrition movements. Early stages emphasize purity and certainty. Later stages quietly reintroduce flexibility when biology refuses to cooperate.Also, Paul is partners with Liver King.The Economic EngineThe economic component remains impossible to ignore.Carnivore influencers rarely restrict themselves to books and podcasts. Instead, they build supplement companies that sell freeze-dried organs, nutrient capsules, and other “ancestral” products. The marketing narrative follows a familiar path.Modern food supposedly lacks essential nutrients.Ancient diets supposedly provided them.Supplements conveniently deliver them.When followers adopt the diet, they often purchase the products associated with it. Over time, they invest not only money, but identity in the movement. As a result, they defend the doctrine aggressively, particularly when new treatments threaten the narrative.The GLP-1 ConflictThis dynamic explains the hostility many carnivore influencers display toward GLP-1 medications, such as semaglutide and tirzepatide.GLP-1 drugs reduce appetite, improve metabolic health, and produce significant weight loss in clinical trials. For many patients, they represent the most effective medical treatment for obesity ever developed.However, GLP-1 therapy undermines the core promise of the carnivore movement. Influencers claim that diet alone solves metabolic disease. Pharmaceutical treatments challenge that claim.Moreover, if people lose weight and improve their health through medical therapy, they may no longer feel compelled to purchase expensive supplements or coaching programs.Consequently, the drugs become ideological enemies.Carnivore influencers often portray GLP-1 medications as dangerous, unnatural, or morally suspect. Their followers repeat these arguments across social media platforms, especially on X (formerly Twitter), where the debate frequently resembles a religious dispute, not a scientific discussion.Within this worldview, GLP-1 therapy resembles a rival faith.And rival faiths provoke rebellion.The Cave Painting ArgumentCarnivore advocates occasionally invoke another argument that sounds persuasive until examined closely.If humans historically consumed vegetables, they ask, why do cave paintings rarely depict them?The answer lies in the purpose of cave art.Prehistoric artists painted dramatic events—hunts, animals, danger, survival. These images celebrated moments that mattered in a world where food sometimes fought back.Nobody returned from hunting mammoths and announced, “Let us commemorate this carrot.”Cave art told stories.It did not document grocery lists.Moreover, the absence of broccoli in cave paintings has an obvious explanation. Broccoli did not exist during the Paleolithic era. Mediterranean farmers cultivated it from wild brassica plants thousands of years later, likely beginning with the Etruscans.Using cave paintings to prove humans were carnivores resembles using medieval paintings to argue that humans never drank coffee.Humans Have Always Been OmnivoresAnthropology provides a far more realistic picture.Scientists studying ancient bones, tools, and coprolites—preserved human feces—consistently find evidence of diverse diets that included roots, tubers, fruits, seeds, fish, and meat.Geography shaped these diets. Arctic populations consumed more animal foods, while equatorial societies relied heavily on plants.However, no civilization in human history survived entirely on beef.Flexibility—not purity—allowed our species to thrive.The Culinary ProblemCarnivore advocates rarely discuss another drawback of the diet.It is monotonous.Human cuisine represents one of the great achievements of civilization. Across cultures, people combine vegetables, grains, spices, and animal foods into extraordinary traditions that reflect geography and history.Reducing that diversity to an endless rotation of ribeye steaks diminishes both nutrition and culture.Beef remains delicious. I enjoy it myself. Growing up on a small island in Alaska, I rarely saw beef because it cost too much to ship. Consequently, it felt special when it appeared at the table.Yet eating beef every day does not create cuisine.It creates repetition.Is the Carnivore Diet Safe?Many readers ask a simple question: Is the carnivore diet safe? Short-term, some people lose weight on a carnivore diet because they eliminate ultra-processed foods and increase protein intake. However, long-term health outcomes remain far less reassuring. Diets that exclude vegetables, legumes, fruits, and whole grains remove important sources of fiber, phytonutrients, and micronutrients that support gut health, metabolic regulation, and cardiovascular protection. Large population studies consistently associate dietary patterns rich in plant foods—such as the...

The Minnesota Starvation Experiment: What Hunger Does to the Human MindEvery few years, someone announces the solution to weight loss.Eat less.Fast longer.Cut carbs.Cut fat.Cut something.Naturally, the advice usually comes with a tone of moral certainty. If you are hungry, the implication goes, you simply lack discipline.However, long before social media, diet influencers, and the phrase food noise entered the modern vocabulary, scientists ran an extraordinary experiment that revealed something profound about hunger.Rather than speculate about appetite, they studied it directly.In the middle of World War II, researchers deliberately starved healthy young men.The results changed how we understand hunger forever.Why the Experiment HappenedDuring World War II, much of Europe faced severe food shortages. Cities were bombed, farms disrupted, and supply chains shattered. Consequently, millions of civilians were suffering from malnutrition and starvation.Yet another problem quickly emerged. Refeeding starving populations turned out to be complicated. If nourishment returned too quickly, dangerous metabolic complications could occur. Doctors needed to understand not only starvation but also recovery from starvation.Therefore, the U.S. government supported research designed to answer a simple but critical question:What happens to the human body and mind when calories are severely restricted for long periods?The scientist leading that effort was Dr. Ancel Keys at the University of Minnesota.Today, Keys is often remembered for his later work on diet and heart disease. Nevertheless, his wartime research produced one of the most remarkable studies ever conducted in nutrition science.The results were eventually published in a monumental two-volume work titled:“The Biology of Human Starvation.”This massive text, published in 1950, remains one of the most detailed examinations of hunger ever written.KEYS, ANCEL, JOSEF BROŽEK, AUSTIN HENSCHEL, OLAF MICKELSEN, HENRY LONGSTREET TAYLOR, Ernst Simonson, Angie Sturgeon Skinner, et al. The Biology of Human Starvation: Volume I. University of Minnesota Press, 1950. https://doi.org/10.5749/j.ctv9b2tqv.The VolunteersTo conduct the study, Keys recruited 36 conscientious objectors.These men had refused military service during World War II for moral or religious reasons. Nonetheless, they still wanted to contribute to the war effort. Participating in this experiment became their way of helping.Importantly, the volunteers were healthy young men. They had normal body weight, good physical fitness, and no significant psychological problems. In other words, they were ideal research subjects.Furthermore, they understood the risks.They would experience months of severe caloric restriction.Even more remarkable, the experiment took place beneath the University of Minnesota football stadium, turning an athletic facility into one of the most important laboratories in nutrition history.The Structure of the ExperimentThe study unfolded in three distinct phases.First came the baseline period. For several months, the men ate normally, consuming approximately 3,200 calories per day. Researchers measured body weight, metabolism, and psychological health to establish a stable starting point.Next came the central part of the experiment: six months of semi-starvation.During this period, calorie intake dropped to roughly 1,500 calories per day. That number may sound familiar because many modern diet programs recommend similar intake levels.The food itself resembled wartime rations. Participants ate simple meals consisting primarily of potatoes, bread, macaroni, turnips, and small amounts of dairy.Although the men remained physically active, their energy intake was cut in half.Finally, the experiment concluded with a refeeding phase designed to observe how the body recovers after prolonged starvation.The Unexpected Psychological EffectsResearchers expected weight loss.What surprised them was the dramatic change in the men’s relationship with food.Gradually, the volunteers became completely preoccupied with eating.First, they began collecting recipes. Soon afterward, they spent hours reading cookbooks.Remember that this was long before television cooking shows or the Food Network. Nevertheless, these men read cookbooks the way other people read novels.Additionally, food became the center of conversation. Participants talked about meals constantly. They debated cooking techniques and discussed ingredients in remarkable detail.Meanwhile, eating itself changed dramatically.Many men developed elaborate food rituals. Some cut meals into tiny pieces to make them last longer. Others chewed gum continuously to quiet hunger. Still others drank large amounts of water or coffee simply to fill their stomachs.Eventually, several participants reported dreaming about food every night.At that point, hunger had completely dominated their mental landscape.When Hunger Changes PersonalityAlongside this intense food focus came significant psychological changes.Participants became irritable.Mood declined.Social withdrawal increased.Furthermore, many men lost interest in hobbies and normal activities. Concentration dropped, and emotional resilience weakened.However, one topic continued to command their attention:Food.In modern terms, we might describe this state as persistent food noise—the constant internal dialogue about eating that many individuals with obesity describe today.The Minnesota experiment demonstrated something important: when the human body senses prolonged energy shortage, the brain amplifies signals related to food.That response is not weakness.Instead, it is survival.What Happened When Food ReturnedThe most striking results appeared during the recovery phase.Once calorie restrictions ended, participants were allowed to eat freely again. Unsurprisingly, many men consumed enormous amounts of food.Daily intake sometimes reached 5,000 to 10,000 calories.Importantly, this response was not driven by pleasure alone. Rather, the body was attempting to restore lost energy reserves and rebuild metabolic balance.Researchers observed that appetite remained elevated for months after the starvation phase ended. In some cases, normal appetite regulation took more than a year to return.Consequently, the study revealed that hunger leaves a lasting biological imprint.Lessons for Modern NutritionAlthough the Minnesota Starvation Experiment occurred more than eighty years ago, its lessons remain highly relevant.Modern weight-loss advice often emphasizes simple calorie restriction. People are told to eat less, ignore cravings, and rely on willpower.Yet the Minnesota study demonstrates that prolonged calorie restriction triggers powerful biological responses.Hunger intensifies.Food becomes mentally dominant.Motivation to eat grows stronger.In other words, the brain fights back.From an evolutionary perspective, this response makes perfect sense. Humans evolved in environments where food scarcity threatened survival. Therefore, the brain developed mechanisms to detect energy deficit and prioritize eating.Those mechanisms remain active today.Hunger, the Brain, and Food NoiseModern neuroscience offers further insight into what the Minnesota researchers observed.Several brain regions participate in appetite regulation. The hypothalamus monitors energy balance through hormones such as leptin, ghrelin, and insulin. Meanwhile, motivational circuits—including the nucleus accumbens—integrate metabolic signals with behavioral drive.When energy stores decline, these systems increase the motivational pull toward food.Consequently, thoughts about eating become more persistent and more difficult to ignore.This process resembles what many patients describe as food noise—a continuous internal signal urging them toward food.The Minnesota experiment showed that this phenomenon can arise even in healthy individuals when calories remain restricted long enough.A Modern Medical PerspectiveToday, treatments for obesity increasingly focus on restoring normal appetite regulation rather than relying solely on behavioral restraint.Medications known as GLP-1 receptor agonists offer one example.Patients using these therapies often report something striking. Many say that the constant mental chatter about food becomes quieter. Meals feel satisfying sooner, and cravings diminish.In other words, regulation returns.These observations reinforce an important idea: overeating may not reflect a lack of discipline. Instead, it may result from disrupted...

Meanwhile, in a LaboratoryIn 1990, researchers isolated a peptide from Gila monster venom. Two years later, work from the Bronx VA Medical Center described exendin-4, a molecule that resembled human GLP-1 but lasted far longer in circulation.Human GLP-1 survives only minutes before the body breaks it down. Exendin-4 resisted that breakdown. That difference changed everything.Soon afterward, the first GLP-1 receptor agonist reached patients under the brand name Byetta. At the time, physicians used it to treat diabetes. No one called it a weight-loss drug. No one predicted it would reshape obesity medicine.And yet, the foundation was already in place.While I Was OperatingAt the Phoenix Indian Medical Center, I performed weight loss surgery in a population with some of the highest rates of type 2 diabetes in the world. Researchers there studied metabolism intensely. The “thrifty gene” hypothesis gained traction in that environment. Scientists asked whether efficient energy storage, once protective in scarcity, became harmful in abundance.At the same time, I watched something remarkable in the operating room. After gastric bypass, patients’ blood sugars often improved within days, before meaningful weight loss occurred. Hormones were shifting. Physiology was driving outcomes.Meanwhile, GLP-1 drugs evolved.Researchers lengthened their half-lives. Chemists modified their structures so they bound albumin and stayed active for days rather than minutes. Clinical trials expanded. Safety data accumulated.Eventually, semaglutide showed average weight loss approaching fifteen percent of body weight in obesity trials. Then tirzepatide, now marketed as Zepbound for obesity, exceeded 20 percent weight reduction in higher-dose studies. In addition, cardiovascular outcome trials demonstrated reductions in major adverse cardiac events in high-risk patients.These were not cosmetic results. These were metabolic and cardiovascular outcomes.Food NoisePatients rarely talk about receptors. They talk about noise.Food noise.The constant internal dialogue about eating. The mental pull toward the pantry. The background chatter that never quite stops.GLP-1 receptors exist in appetite-regulating areas of the brain, including the hypothalamus and brainstem. These medications act through vagal signaling and through regions where the blood-brain barrier is more permissive. As a result, they modulate satiety and reward pathways.Consequently, many patients report something simple but profound: the noise quiets.Not disappears. Quiet.That distinction matters.Diet Culture PushbackPredictably, not everyone celebrates this shift.Diet culture thrives on the belief that weight reflects character. Some coaches insist the solution is fewer calories. Others argue for more beef, more butter, more fiber, or stricter discipline. Entire industries depend on the idea that trying harder solves everything.However, biology does not negotiate with virtue.Obesity is a chronic, relapsing, neurohormonal disease. No one worked harder at weight loss than many of my surgical patients. Likewise, I do not lack willpower. And I practice culinary medicine. Preaching and eating a Mediterranean diet.Nevertheless, effort alone does not silence dysregulated signaling.Calling GLP-1 therapy “cheating” misunderstands the science. These medications restore signaling. They amplify satiety. They reduce excess reward drive. They support physiology.That is treatment, not moral compromise.My Parallel UniverseWhen I began my career, I weighed about 185 pounds. Years later, hospital cafeterias, exhaustion, and irregular meals pushed me to 225. I understood obesity clinically. Then I understood it personally.In one version of my career, revision surgery remains the answer for weight regain. In this version, I reached for GLP-1 therapy instead.Today, I weigh what I weighed when Nixon was president.I am both surgeon and patient.And your reporter.A Necessary CautionGLP-1 medications carry risks as well as benefits. Nausea can occur. Gastric emptying slows. Gallbladder disease risk may increase, although obesity itself already raises that risk substantially. Physicians must monitor dosing carefully.Therefore, if you consider GLP-1 therapy, work with a trained physician who understands obesity medicine. Avoid quick online scripts. Seek supervision. Demand follow-up.Metabolic medicine deserves serious care.The Desert Was the BeginningI once thought Phoenix was punishment. The heat felt relentless. Even Satan might choose a cooler vacation. Only Canadians brave July—and who can blame them?However, what felt like exile turned out to be preparation.In that same desert, I learned surgery. Researchers debated the thrifty gene. A venomous lizard carried a peptide that would become the basis of modern metabolic therapy.I thought I had been sent to hell. But I found beauty in the desert, and by the time I left Arizona, I missed it terribly.Little did I know I was sent to the future in Arizona.

Protein Panic: How Much Do You Really Need?Everywhere you look, protein has become a competition.Scroll long enough and you will believe muscle disappears if you eat less than 150 grams a day. Meanwhile, influencers debate leucine thresholds like they’re trading baseball cards. As a result, ordinary meals now feel like math problems.However, biology does not require panic.Protein matters. Yet adequacy differs from excess. And importantly, most people eating real food already meet their needs.So let’s slow down.First, What Protein Actually DoesProtein builds and repairs tissue. In addition, amino acids support immune function and hormone signaling. Furthermore, specific amino acids such as leucine trigger muscle protein synthesis.Nevertheless, once you reach the effective leucine threshold in a meal, adding more protein does not multiply muscle growth. Instead, your body oxidizes the excess.Therefore, more does not always mean better.How Much Is Enough?For most healthy adults, about 0.8 grams per kilogram of body weight covers basic needs. Meanwhile, adults over 60 often benefit from 1.0 to 1.2 grams per kilogram to protect lean mass.Notably, that recommendation does not require heroic intake. In fact, a 75–80 kilogram adult typically lands between 60 and 90 grams per day.Consequently, many people hit those numbers without even trying.Here’s What I Actually DoI do not count protein. I never log grams. Moreover, I do not calculate leucine before breakfast.Instead, I eat normal meals.Most mornings, I have a shake. The recipe lives on terrysimpson.com. That shake provides roughly 25 grams of protein. Sometimes I add PB Fit. Occasionally, I include Greek yogurt. As a result, I increase protein slightly without thinking about it.Later, I eat three to five ounces of chicken breast with Louisiana hot sauce. That adds another 25 grams.Then at dinner, I often choose salmon and chickpeas. Together, they bring me to roughly 70–80 grams for the day.Importantly, I have lost 50 pounds and preserved muscle mass. I track muscle periodically. I see no decline.So what about leucine?High-quality animal protein contains about 8–10% leucine. Therefore, a 25-gram protein meal delivers about 2 grams of leucine. That amount typically triggers muscle protein synthesis.Thus, I hit the effective threshold at each meal without obsessing.Now Let’s Bring In GLP-1GLP-1 medications reduce appetite. Consequently, total intake drops. Because of that, protein intake can fall too.So yes, people using GLP-1 should pay attention. However, they do not need 180 grams per day. Instead, they need adequacy and resistance training.Lift something heavy. Spread protein across meals. Preserve lean mass.Simple.Here’s the Real DeficiencyProtein deficiency remains rare in the United States. By contrast, fiber deficiency remains common.According to the National Institutes of Health, most adults fail to meet recommended fiber intake levels. In fact, average intake falls far below the 25–38 grams per day recommended for adults.(Reference: NIH Office of Dietary Supplements – Fiber Fact Sheet)Meanwhile, high-protein diets often crowd out legumes, whole grains, and vegetables.So while people panic about protein, they quietly neglect fiber.And fiber feeds the microbiome. Fiber improves glycemic control. Fiber lowers LDL cholesterol.Protein builds muscle. Fiber protects metabolism.Both matter.Mediterranean Patterns Keep It BalancedMediterranean-style eating provides protein from fish, legumes, yogurt, and moderate poultry. At the same time, it supplies fiber from beans, vegetables, and whole grains.Therefore, protein arrives packaged with micronutrients and fermentable substrate.Unlike protein powders and bars, real food supports multiple systems at once.Consequently, longevity patterns emphasize diversity, not maximal single-nutrient intake.The TakeawayAdequate protein preserves muscle. Resistance training drives adaptation. Fiber protects metabolic health.So before you triple-scoop whey, pause.Ask yourself whether you lack protein — or whether you lack plants.Because protein matters.Panic does not.And once again, data beats dogma.

Why Traditional Mexican Food Is Healthy — and How America Got It WrongEvery time someone says Mexican food is unhealthy, I know exactly what they’re picturing.They aren’t picturing Mexico.They’re picturing an American taco: a hard shell or a fluffy white flour tortilla, fatty hamburger, sour cream, a thin smear of salsa that contributes almost nothing except salt, and a yellow substance legally allowed to be called cheese.After eating that, they naturally conclude Mexican food is the problem.That conclusion doesn’t come from biology. It comes from branding.Traditional Mexican food looks nothing like that. More importantly, it behaves nothing like that once it hits your body.So let’s slow down, take a breath, and do what we always do here—follow the evidence, not the vibes.First, Let’s Talk About the Taco America Put on TrialThe American taco stacks the deck against itself.It leads with saturated fat, piles on refined carbohydrates, and adds dairy on top of dairy. Meanwhile, it offers almost no fermentable fiber. The gut gets nothing to work with. Blood sugar spikes. Inflammation follows.That taco doesn’t help anyone.But here’s the key point: it isn’t Mexican food.It’s ultra-processed American convenience food wearing cultural drag.Now Let’s Look at a Real TacoBy contrast, a traditional taco starts very differently.It starts with a corn tortilla, not refined flour. Then it adds beans. After that, it layers vegetables, real salsa, and often cabbage. Finally, it finishes with avocado. Sometimes it includes fish. Sometimes it doesn’t. Either way, the structure holds.And structure matters.Because when you look at how that meal behaves biologically, it stops looking indulgent and starts looking smart.Corn Tortillas Aren’t the Villain — They’re the FoundationFirst of all, traditional corn tortillas come from nixtamalized corn. That process treats corn with lime, and no, that isn’t trivia.Instead, nixtamalization improves mineral absorption, improves protein quality, and preserves resistant starch.As a result, resistant starch passes through the small intestine untouched. Then it reaches the colon, where gut bacteria ferment it. Consequently, those bacteria produce short-chain fatty acids, especially butyrate.And here’s the important part: butyrate fuels the cells lining your colon. In addition it strengthens the gut barrier. It reduces inflammation. Finally, it improves metabolic signaling.So no, this isn’t a carb disaster. On the contrary, it’s colon nutrition.Beans Do the Heavy Lifting — And They Always HaveNext, add beans.At that point, the conversation usually derails, so let’s keep it grounded.A serving of beans delivers roughly ten grams of fiber. Not one kind — several kinds. Soluble fiber. Insoluble fiber. Resistant starch. Plus protein.Because of that, beans slow digestion. They flatten glucose curves. They improve satiety. Most importantly, they feed gut bacteria that matter.Specifically, bean fiber supports Akkermansia, a gut bacterium associated with better insulin sensitivity and a stronger gut barrier.In other words, beans don’t fill space. Instead, they build infrastructure.And yes, when you pair beans with rice, you get a complete amino acid profile. Humans figured that out centuries ago, long before protein powders and “ancestral” snack companies tried to monetize it.Now Let’s Deal With Refried Beans — Because This Is Where People PanicAt this point, someone inevitably says, “But what about refried beans?”So let’s clear that up.First, frijoles refritos does not mean “fried twice.” It means well-fried or thoroughly cooked. Traditionally, people cooked beans, then lightly cooked them again, often mashing them for texture.So yes — refried beans are traditional. Very traditional.Moreover, mashing beans does not remove fiber. Cooking beans does not turn them into sugar. Beans remain beans.So where did refried beans go wrong?Fat choice.Historically, many refried beans used lard. That made sense when calories were scarce and undernutrition threatened survival. However, in a modern context, large amounts of lard mean large amounts of saturated fat.Therefore, when refried beans swim in lard, then get buried under cheese, then land inside a refined flour tortilla, the problem isn’t the beans. The problem is the fat context.Fortunately, this problem has an easy fix.Use olive oil or another unsaturated fat. Add onions and garlic. Mash lightly, not into paste. Suddenly, refried beans snap right back into a Mediterranean-style pattern.And yes — some commercially available refried beans already do this. Look for short ingredient lists. Look for beans, oil, onion, garlic, salt. Skip the lard. Skip the mystery fats. Your gut will notice.Avocado Doesn’t Add Calories — It Unlocks NutritionThen comes avocado, which people love to blame for reasons that make no biological sense.Avocado provides about five grams of fiber and a meaningful amount of monounsaturated fat — the same fat family as olive oil.More importantly, fat enables absorption of fat-soluble vitamins: A, D, E, and K.So when you add avocado to vegetables, you don’t ruin the meal. Instead, you make the nutrients available.In other words, avocado doesn’t cancel vegetables. It activates them.Salsa and Cabbage Quietly Do the Real WorkMeanwhile, real salsa brings tomatoes, onions, garlic, chilies, and cilantro to the table. That means fiber. That means polyphenols. That means fermentable substrate for gut bacteria.Add corn to the salsa and you add more whole grains and more resistant starch.Then add cabbage — raw or lightly dressed — and now you feed short-chain fatty-acid producers directly.Nothing exotic. Nothing trendy. Just food that works.Step Back — Because This Should Look FamiliarNow zoom out.Traditional Mexican food emphasizes whole grains, legumes, vegetables, unsaturated fats, and fermentation. It stays naturally low in saturated fat. It supports the microbiome. It respects digestion.In other words, it follows the Mediterranean pattern.Not because it sits near the Mediterranean Sea — but because biology doesn’t care about geography.The Mediterranean diet is a structure, not a destination.Whether you eat it in Greece.Or you eat it in Italy.But you can eat it wrapped in a corn tortilla.So What Actually Broke the Taco?Processing.Refining grains.Deep-frying bases.Replacing beans with beef.Replacing water with sugar.Turning cheese into a load-bearing wall.Mexican food didn’t fail.Industrial food did.The VerdictA traditional taco — corn tortilla, beans or properly made refried beans, vegetables, avocado, real salsa, maybe fish — fits squarely into one of the healthiest dietary patterns we know.Different culture.Same biology.So the next time someone tells you Mexican food is unhealthy, remember this:The taco was framed.And once again — data beats dogma.

Why Fiber Fails to Impress—and Why That’s the PointFiber has a public relations problem. Unlike supplements or extreme diets, fiber does not promise instant transformation. Instead, it works slowly, predictably, and quietly. Because of that, people rarely notice it when it’s doing its job well. However, that very boredom is precisely why fiber matters.When fiber intake is adequate, digestion functions normally, blood sugar behaves more consistently, and bowel habits stay predictable. As a result, there is no drama to post on social media. Consequently, influencers move on. Meanwhile, the science stays exactly where it has been for decades: fiber lowers disease risk over time.That kind of quiet effectiveness may not sell products, but it saves lives.“Fiber Isn’t Essential”—Why That Argument Misses the MarkTechnically speaking, fiber is not an essential nutrient in the classic sense. In other words, there is no disease caused solely by a lack of fiber the way scurvy results from vitamin C deficiency. Because of this, critics often stop the conversation there.However, medicine does not ask only whether you survive. Instead, it asks whether your risk of chronic disease rises or falls over time. On that front, fiber consistently lowers the risk of colon cancer, improves glucose regulation, reduces constipation, and supports cardiovascular health. Therefore, while you can live without fiber, you do not age particularly well without it.Protein Gets the Spotlight While Fiber Does the WorkAt the same time, nutrition conversations fixate on protein. Protein goals dominate podcasts, social media, and supplement aisles. Yet, in practice, true protein deficiency in the United States is rare, even among bariatric surgery patients.In contrast, fiber deficiency is the norm. Roughly 92% of Americans fail to meet recommended fiber intake. As a result, constipation becomes common, long bathroom visits feel normal, and scrolling on a phone in the bathroom gets rebranded as “self-care.” Unfortunately, that normalization hides a real problem.A Personal Lesson From Oats, Gas, and a Scorched DeskYears ago, I learned a fiber lesson the hard way. After deciding to increase my fiber intake quickly, I started eating steel-cut oats every morning during a busy meeting week. At first, everything seemed fine. Soon, however, my digestive system made it clear that it had not been consulted in this decision.By the second day, bloating appeared. By the third day, office etiquette became questionable. Consequently, I lit a candle at my desk. Unfortunately, I turned my back, and papers caught fire. Although the flames were extinguished quickly, the scorch mark stayed for years.That stain served as a reminder: fiber works best when introduced gradually. Your gut adapts over time. Confidence without patience, on the other hand, leads to unnecessary consequences.Not All Fiber Works the Same WayUnderstanding fiber helps people stop fearing it. Soluble fiber, found in oats, barley, beans, lentils, psyllium, apples, and citrus, forms a gel in the gut. Because of this, it slows absorption, reduces glucose spikes, and lowers LDL cholesterol. Consequently, psyllium appears in clinical guidelines rather than influencer protocols.Meanwhile, insoluble fiber focuses on mechanics. It adds bulk, speeds transit, and improves regularity. Importantly, this matters even more for people using GLP-1 medications, where slowed digestion often leads to constipation. In that setting, fiber is not optional—it is foundational.Finally, fermentable fiber feeds gut bacteria. Beans, onions, garlic, asparagus, chicory root, and resistant starch nourish beneficial microbes. As these bacteria grow, they produce short-chain fatty acids, especially butyrate, which supports gut barrier function and immune regulation.No, Butter Is Not a Shortcut to ButyrateDespite what circulates online, butter does not meaningfully deliver butyrate to your colon. Although butter contains trace amounts of butyric acid, that fat is absorbed in the small intestine long before it reaches the colon. In contrast, the butyrate that protects colon health is produced by bacteria fermenting fiber directly in the colon.Therefore, if butter were an effective therapy, gastroenterologists would prescribe croissants. They do not.Supplements Help—but Food Still WinsFiber supplements can be useful. Psyllium and methylcellulose typically provide four to five grams of fiber, which helps people start. However, that amount represents only about ten percent of a reasonable daily target.Personally, I use Loam, which provides around twelve grams of mixed fiber in a smoothie. Nevertheless, supplements act as bridges, not destinations. Ultimately, food does the heavy lifting.IBS, FODMAPs, and Why We Avoid Diet CosplaySome people with IBS feel worse when fermentable fiber increases too quickly. Because fermentation produces gas, symptoms can flare initially. For that reason, clinicians use FODMAPs as a temporary elimination tool to identify triggers.However, elimination is not the end goal. Instead, we reintroduce foods within a Mediterranean dietary pattern, which promotes diversity and tolerance. In contrast, Whole30 markets itself as elimination but functions primarily as low-carb restriction. That approach avoids symptoms rather than solving them.What Eating Enough Fiber Actually Looks LikePeople do not eat grams of fiber. They eat meals. A Mediterranean-style day, such as the 3-Day Mediterranean Diet at terrysimpson.com, delivers fiber incidentally.Breakfast often includes oats, berries, and nuts. Lunch typically features vegetables, legumes, whole grains, and olive oil. Snacks rely on fruit, nuts, or hummus. Dinner centers on vegetables, whole grains like farro, and fish or poultry. Over the course of a day, fiber naturally reaches 25–40 grams without spreadsheets or stress.Start Slowly, Then Stay ConsistentIf you currently eat little fiber, the solution is simple but not dramatic. Increase intake gradually. Drink water. Give your microbiome time to adapt. Although you are not fragile, abrupt change can still cause discomfort.The Bottom LineFiber does not need hype. Instead, it needs consistency. It works quietly, steadily, and reliably. If bathroom visits require entertainment, the issue is not age—it is fiber.

Food Noise Isn’t Hunger — and Why Broccoli Never Fixed the BrainFood noise does not announce itself politely. Instead, it hums in the background, persistent and exhausting. For years, patients tried to describe it. Meanwhile, medicine largely ignored it. Recently, however, GLP-1 receptor agonists forced the conversation into the open.I did not understand food noise myself until it stopped.About twelve hours after my first GLP-1 injection, I stood in my kitchen waiting for baked salmon to finish cooking. Nothing dramatic happened. No emotional moment followed. Still, something felt different. The internal commentary was gone. The negotiations disappeared. For the first time, my brain felt quiet.At that moment, I finally understood what patients had been telling me for years. First, Define the Problem ClearlyFood noise is not hunger. Hunger serves a biological purpose. In contrast, food noise describes persistent, intrusive thoughts about food that occur regardless of energy needs. People experience rumination, preoccupation, cravings, and mental fatigue—even when they are physiologically full.Importantly, this phenomenon is now measurable. The Food Noise Questionnaire validates what patients already knew. Specifically, it assesses the frequency of food thoughts, difficulty controlling them, interference with daily activities, emotional distress, and craving intensity. In other words, food noise exists independently of willpower.Consequently, advice that targets hunger alone inevitably fails. Next, Address the Broccoli MythI eat vegetables. Nevertheless, I have never liked broccoli.Frankly, if broccoli is air-fried to the edge of carbonization, I will tolerate it. That concession, however, does not transform broccoli into a neurological intervention. Fiber increases fullness. Protein improves satiety. Vegetables slow digestion. None of those actions quiet the reward centers of the brain.Put simply, broccoli fills the stomach. Food noise lives elsewhere.Because of that distinction, the “just eat for satiety” argument collapses under scrutiny. Then, Follow the Science Where It LeadsFood noise arises from heightened food-cue reactivity. Visual cues, smells, availability, and anticipation activate reward pathways long before food reaches the stomach. Ultra-processed foods amplify this response. Their engineered combinations of refined carbohydrates, fats, salt, and flavor compounds reliably stimulate the mesolimbic dopamine system.As a result, ultra-processed foods increase wanting rather than liking.However—and this matters deeply—removing ultra-processed foods does not automatically restore normal appetite signaling. Once reward circuitry becomes dysregulated, dietary virtue alone cannot reset it. At that stage, telling someone to “just eat whole foods” resembles telling someone with tinnitus to “enjoy the silence.”Therefore, ultra-processed foods contribute to the problem, but they do not explain it entirely. Now, Enter GLP-1 Receptor AgonistsGLP-1 receptor agonists act centrally and peripherally. While many people fixate on gastric emptying, the central mechanisms explain the lived experience.In the hypothalamus, GLP-1 receptor agonists activate satiety-promoting POMC/CART neurons while inhibiting hunger-promoting NPY/AgRP neurons. This dual action reduces homeostatic hunger. Meanwhile, in the brainstem—particularly the nucleus tractus solitarius—GLP-1 signaling integrates gut-brain communication and sustains appetite suppression.More importantly, GLP-1 receptor agonists modulate reward circuitry. In regions such as the ventral tegmental area and nucleus accumbens, these agents dampen dopamine signaling. Consequently, food becomes less compelling rather than forbidden.Functional imaging studies confirm this effect. After GLP-1 treatment, brain responses to food cues decrease in the insula, amygdala, orbitofrontal cortex, and related regions. The brain still recognizes food. It simply stops obsessing.As a Result, Behavior Changes Without ForceOnce food noise quiets, people do not suddenly become disciplined saints. Instead, they become selective.In my own case, wine lost its appeal. I did not swear it off. I simply stopped wanting it. Eventually, I quit five wine clubs. When a glass tastes mediocre, I put it down and choose iced tea. That behavior reflects altered reward signaling, not moral growth.Similarly, food choices shift without struggle. People stop eating things merely because they are available. They stop drinking because something is poured. The absence of compulsion creates space for intentional eating.That distinction explains why GLP-1 therapy feels different from appetite suppression.Finally, Place Diet Back Where It BelongsThe Mediterranean diet improves health. I recommend it. I eat it. Still, it does not cure food noise.Diet supports metabolic health once interference disappears. GLP-1 therapy removes that interference. Together, they work better than either alone. Pretending otherwise leads to fat shaming disguised as nutritional advice.Obesity is a disease. GLP-1 receptor agonists treat that disease. Food then becomes nourishment rather than negotiation. So, What Actually MattersUltra-processed foods worsen food noise, yes. Yet removing them does not repair dysregulated reward circuitry. Satiety fills the stomach. GLP-1 therapy quiets the brain. Once the noise fades, nutrition finally has a fair chance.In the end, broccoli keeps my mother from returning from the grave. GLP-1s keep my brain quiet. Both have their place. Only one treats the disease. REFERENCES:1. Medications for Obesity: A Review.The Journal of the American Medical Association. 2024.

Whole Milk Is Back in SchoolsBut Hungry Kids Are Still the Real ProblemWhole milk is back in school cafeterias.As a result, a lot of people are celebrating. Some are calling it a victory for nutrition. Others are calling it common sense. Meanwhile, a few are even calling it a breakthrough.However, that excitement misses the point.Because the biggest problem facing kids in school today is not milk fat.Instead, the real problem is hunger.First, Let’s Start With the ObviousBefore we talk about milk, fat, or nutrients, we need to start with something very basic.Hungry kids do not learn well.In fact, hunger affects attention, memory, and behavior. As a result, students who do not eat enough struggle to focus. Over time, that struggle shows up as lower academic performance.Because of that, no change to milk will ever fix an empty stomach.Therefore, if we want better outcomes, we have to start with food access.Next, What Actually Changed With MilkDespite what many people believe, whole milk was not removed from schools in the past.Instead, schools continued to offer low-fat and fat-free milk.Importantly, those options provided the same essential nutrients:proteincalciumpotassiumiodinevitamin B12In addition, vitamin D was added through fortification, regardless of milk fat level.So, children did not lose vital nutrients.What they lost was milk fat.Now, Why Milk Fat Is Not EssentialMilk fat is made mostly of saturated fat.That matters because saturated fat is not an essential dietary nutrient.If the human body needs saturated fat, it can make it on its own. In other words, there is no requirement to eat it for normal growth or brain development.As a result, adding more saturated fat to a child’s diet is not necessary.Then, Let’s Talk About the BrainHere is where biology matters.The brain is built largely from polyunsaturated fats, not saturated fats.These polyunsaturated fats keep cell membranes flexible. Because of that flexibility, brain cells can signal, adapt, and learn.In contrast, saturated fat is rigid. It plays only a small structural role in membranes. If membranes contained too much saturated fat, they would become stiff. When that happens, signaling does not work well.For that reason, biology uses saturated fat sparingly.Therefore, less saturated fat in the diet of growing children is actually better for long-term brain and cardiovascular health.Meanwhile, What Kids Are Really MissingIf there is one nutrient that most children lack, it is fiber.Fiber supports gut health. In addition, it improves insulin sensitivity. Over time, it also reduces cardiovascular risk.Milk fat does none of those things.So, if nutrition is the concern, fiber deserves more attention than nostalgia for saturated fat.At the Same Time, Food Access Is ShrinkingWhile milk is being discussed, something else is happening quietly.Food assistance programs are being reduced.That matters because programs like SNAP do more than help families buy groceries. They also help children qualify for free school meals.When eligibility is reduced, fewer children qualify. As a result, schools receive less funding for lunch programs. Consequently, some schools serve fewer meals. In certain communities, programs disappear entirely.Therefore, the outcome is simple: fewer kids eat at school.In Contrast, Feeding Kids Actually WorksSome states have shown a different approach.When children receive meals consistently, attendance improves. At the same time, concentration improves. Over the long term, educational outcomes improve as well.This result has been seen repeatedly.Because of that, feeding kids is not charity. Instead, it is an investment in education, health, and future productivity.So, Let’s Put This TogetherWhole milk is fine.If families enjoy it, they can drink it. If schools offer it, that is acceptable.However, whole milk is not an innovation.Feeding children is.Ultimately, school meals should not be treated as a budget line to debate each year. Instead, they should be treated as part of what a functioning society does for its kids.One Reference on Brain Fat and Cell MembranesFor readers who want the science behind membrane fats and brain function, this review explains it clearly:Stillwell W, Wassall SR.Docosahexaenoic acid: membrane properties of a unique fatty acid.Chemistry and Physics of Lipids. 2003;126(1):1–27.This paper explains why polyunsaturated fats keep membranes flexible and why saturated fats play only limited roles.

When Influencers Replace Scientists, Everyone LosesEvery few years, nutrition gets a makeover.First comes a new graphic.Then comes a new slogan.Soon after, we hear claims that this time, someone finally figured it all out.Recently, that makeover arrived in the form of a “reverse food pyramid” and the cheerful phrase “Eat Real Food.” On the surface, that message sounds reasonable. In fact, many doctors have said the same thing for decades.However, the real problem isn’t the slogan.Instead, the problem lies in who is now shaping nutrition advice—and who is not.Yes, Some of the Advice Is RightTo be clear, let’s start with agreement.Eating real food helps health.Limiting added sugar makes sense.Reducing ultra-processed foods improves outcomes.Importantly, none of this is new.Doctors, dietitians, and public-health researchers have said these things for years. Because of that, when influencers now say, “See, we were right,” a serious issue appears.They didn’t discover this information.They copied it.The Real Risk Isn’t AgreementAt first glance, agreement sounds harmless.Nevertheless, agreement becomes dangerous when it turns into ownership.Once someone believes they have discovered basic nutrition truths, they often assume they can rewrite everything else. As a result, bad ideas slip in quietly, wrapped in confidence instead of evidence.That shift matters.Scientists and Influencers Are Not InterchangeableAt this point, we need to say something clearly.We cannot afford to replace scientists with influencers.Nutrition science didn’t come from podcasts or social media. Instead, it came from metabolic ward studies, long-term population research, and randomized trials. Moreover, real scientists accept uncertainty. They change their minds when the data changes.By contrast, influencer culture rewards certainty.Even worse, confidence often replaces humility.There is no “Mediterranean diet influencer community.”Likewise, there is no “DASH diet movement.”Those dietary patterns exist because scientists studied them, tested them, and measured outcomes over time.On the other hand, a loud low-carb and carnivore influencer ecosystem does exist. That ecosystem includes brands, supplements, coaching programs, and a strong contrarian identity. Because of that structure, influence—not evidence—often drives the message.Fiber Versus Saturated Fat: A Telltale SignIf you want to know whether someone understands nutrition science, ask a simple question:Which matters more—fiber or saturated fat?Influencers often say, “Fiber isn’t an essential nutrient.”Technically, that statement is true in the narrowest sense.However, context matters.Fiber supports a healthy gut microbiome.Additionally, fiber improves insulin sensitivity.Furthermore, fiber lowers cardiovascular risk.Finally, fiber supports colon health.Because fiber feeds beneficial gut bacteria, entire fields of microbiome research depend on it.Now compare that with saturated fat.Saturated fat is truly non-essential.Your body can make all it needs.No deficiency disease exists from avoiding it.Even more importantly, excess saturated fat raises LDL cholesterol and worsens artery health. Over time, that increases cardiovascular risk.So ask yourself this:Why dismiss fiber as optional while quietly promoting saturated fat?That choice reflects ideology, not biology.The Brain Doesn’t Care About TrendsHere’s another reality check.Your brain—the most important organ you own—relies heavily on polyunsaturated fats. These fats support cell membranes, nerve signaling, and blood flow.Ironically, these same fats often get labeled “seed oils” and dismissed.Meanwhile, saturated fat does not belong in high amounts in brain tissue. Worse still, saturated fat can clog the arteries that supply the brain.Biology does not respond to marketing.Physiology does not care about popularity.The “You’re On Your Own” ProblemAnother issue deserves attention.After influencers step into the spotlight and claim credit for old science, they often step away from responsibility. Then they tell the public to “figure it out.”That approach ignores reality.Many Americans live in food deserts.Even more rely on school meals.Lots of Americans work multiple jobs.Many lack time, money, or kitchens.Public health exists because willpower alone does not scale. Without system-level support, advice turns into abandonment.Agreement Does Not Equal ExpertiseRecently, debates around nutrition have highlighted this pattern clearly.Some influencers argue that because they agree with basic nutrition advice, they deserve authority over the rest of the science. Unfortunately, agreement does not grant expertise.Copying conclusions does not mean you earned them.Science rewards method, not confidence.The Bottom LineYes, eat real food.And clearly, limit added sugar.Most definitely, reduce ultra-processed foods.Doctors have said this for years.However, flipping a pyramid does not change biology.Likewise, sidelining scientists does not improve health.Finally, promoting saturated fat while dismissing fiber misleads the public.People do not fail diets.Systems fail people.When we trade evidence for influence, health suffers.A Final NoteThis article provides general education, not personal medical advice. Always talk with your healthcare professional about individual nutrition needs.At Your Doctor’s Orders, we believe data matter more than dogma, and evidence matters more than trends.Because when it comes to health, confidence without science is not bold.It’s risky.

Ultra-Processed Food: Making Sense of the MadnessUltra-processed food has become the villain of modern nutrition.Scroll through social media, and you’ll hear that it’s poisoning us, wrecking our gut, and driving the obesity epidemic all by itself.At the same time, other voices dismiss the entire idea as fear-mongering.According to them, processing doesn’t matter at all.Neither extreme tells the full story.So instead of slogans, let’s talk about what ultra-processed food actually means, why people want to blame it, where the science is strong, and where it starts to drift into storytelling.Why We’re Looking for Something to BlameThe obesity epidemic is real.Rates have climbed for decades, and people understandably want answers.Human biology didn’t suddenly change in the 1980s.Willpower didn’t vanish overnight.Something in our environment shifted.Food is an obvious suspect.Because food changed, many people assume there must be a single culprit hiding in the ingredient list.That belief leads to bold claims.Some say Europe bans certain additives and therefore avoids obesity.In reality, obesity rates continue to rise across Europe as well.Others argue that specific ingredients damage the gut, letting in more calories or triggering metabolic chaos.Those ideas sound scientific, especially when they involve complex biology.However, when a problem is large and complicated, humans naturally want a cause that feels simple and controllable.Blaming one ingredient feels easier than confronting patterns of eating, stress, time pressure, and convenience.Biology, unfortunately, rarely offers cinematic villains.What “Ultra-Processed” Actually MeansTo understand the debate, definitions matter.Researchers use the NOVA classification system to describe food processing.NOVA does not rate healthfulness.Instead, it categorizes food by how manufacturers produce it.The system includes four groups.First come whole or minimally processed foods, such as vegetables, beans, eggs, and fish.Next are culinary ingredients like oil, sugar, salt, and flour.Then come processed foods, including bread, cheese, yogurt, and canned vegetables.Finally, NOVA defines ultra-processed foods as industrial formulations.These products often combine refined ingredients with additives, stabilizers, emulsifiers, and flavor systems that home cooks rarely use.Here’s the crucial point.Ultra-processed food is defined by how it is made, not by what it does in the body.That distinction often gets lost.As a result, soda and whole-grain bread can fall into the same category, even though they behave very differently nutritionally.Why Ingredient Blame Falls ShortAt this point, many discussions take a wrong turn.Instead of asking how people eat, the conversation focuses on what to ban.Ingredients become the enemy.Yet most claims about additives rely on animal studies using doses far higher than what humans consume.Human data remains limited and inconsistent.Meanwhile, the bigger picture often gets ignored.Ultra-processed food correlates with stress, long work hours, poor sleep, and limited time for cooking.Those factors influence eating behavior regardless of ingredients.When people feel rushed and overwhelmed, they don’t just eat differently.They eat faster, snack more often, and rely on foods that require little effort.That context matters.The Simple Question That Changed the ConversationInstead of chasing villains, one researcher asked a much simpler question.Do people eat more when food is ultra-processed, even when nutrition looks the same on paper?That question led to the most important experiment in this entire debate.What Kevin Hall Actually FoundAt the National Institutes of Health, Kevin Hall conducted a tightly controlled feeding study.Participants lived in a metabolic ward.Researchers controlled the environment, the meals, and the measurements.Each participant ate two diets.One diet consisted mostly of ultra-processed foods.The other relied on minimally processed foods.Importantly, researchers matched calories, protein, fat, carbohydrates, sugar, and salt.People could eat as much as they wanted.The result surprised almost everyone.On the ultra-processed diet, participants consumed about 500 extra calories per day.Yet, they didn’t report more hunger.They didn’t feel less full.However, they simply ate more.This finding matters because it avoids speculation.No ingredient theories appear here.No gut damage claims drive the conclusion.Ultra-processed food made it easier to eat more calories without noticing.Sometimes the most powerful answers are also the least dramatic.Why a Book Made This Go ViralThat study helped fuel widespread interest, including the success of Ultra-Processed People: The Science Behind Food That Isn't Food by Chris van Tulleken.Van Tulleken, a British physician, took a personal approach.He ate a diet dominated by ultra-processed foods and documented the effects.Weight gain followed.Hunger became harder to regulate.Energy and mood shifted.The book resonated because it made an abstract concept feel personal.It also highlighted how modern foods often prioritize shelf life, softness, and convenience.Stories like this help people recognize patterns they already sense in daily life.However, a compelling narrative does not replace careful interpretation.Where the Story Goes Too FarUltra-processed food is not one thing.It does not act through a single mechanism.The research faces several challenges.First, heterogeneity clouds interpretation.Grouping soda and yogurt together creates confusion rather than clarity.Second, confounding remains a major issue.People who eat more ultra-processed food often face structural barriers that affect health in many ways.Third, additive panic oversimplifies biology.Mouse data cannot stand in for long-term human outcomes.Ultra-processed food may contribute to health problems, but it rarely acts alone.A Better Way to Think About FoodRigid rules tend to fail.Real eating happens in real life.Instead of asking whether a food qualifies as ultra-processed, better questions help guide choices.Does the food contain fiber?How will it contribute protein or micronutrients?Finally, will it replace a balanced meal or help create one?Can you eat it mindfully and stop when satisfied?Foods like yogurt, tofu, olive oil, canned beans, and frozen vegetables often break simplistic rules.Yet they support healthy eating patterns when used well.Processing did not ruin our food.Confusion did.The Bottom LinePeople want a villain because villains feel actionable.Science, however, often points toward behavior rather than ingredients.Ultra-processed foods encourage faster eating, softer textures, and higher calorie intake.That pattern explains a great deal without invoking conspiracies.Understanding that reality empowers better choices than fear ever could.ReferenceHall KD, Ayuketah A, Brychta R, et al.

Willpower Is B.S.: Food Noise, Healthspan, and What Actually Changed My LifeFor decades, I started every New Year the same way.In January, I promised myself this would be the year.By February, I tried harder.Every spring, I adjusted the plan.And by summer or fall, the weight crept back.That cycle repeated not because I lacked knowledge, discipline, or effort. Instead, it repeated because I misunderstood biology — at least when it came to myself.This year is different.For the first time since Ronald Reagan was first elected, weight loss is not at the top of my New Year’s resolution list. Not because I stopped caring, but because I lost 45 pounds with the help of Zepbound over the last year. More importantly, however, I learned something that reshaped how I think about obesity, healthspan, and shame.Before anything else, let me be clear: this is not medical advice. This is a story. Anecdotes are not evidence, even when the anecdote is from a physician. Nevertheless, stories help us understand science when data alone fails to move us.And this story matters.I Had Willpower. That Wasn’t the Problem.For years, people told me — and millions of others — the same thing: move more and eat less. At first glance, that advice sounds logical. After all, calories matter. Energy balance matters.However, reality is more complicated.To begin with, I am a surgeon. Surgical training requires extraordinary willpower. Moreover, I’ve logged food meticulously, cooked Mediterranean-style meals, exercised consistently, and followed every evidence-based recommendation I’ve ever given patients.Meanwhile, Oprah has willpower. Olympic athletes have willpower. Yet obesity persists.Sure, willpower works briefly. In fact, go on a liquid protein diet, and the weight will fall off quickly. Unfortunately, the food noise remains. Eventually, biology wins. Always.In the same way you cannot positive-think your way out of hypertension, cholesterol, diabetes, cancer, or heart disease, you cannot willpower your way out of obesity. Obesity is a disease. It is not a moral failure.Ironically, I knew this intellectually. Nevertheless, I failed to apply it to myself. We have a name for that: cognitive dissonance.Food Noise Was the Missing ConceptThe real turning point did not come from reading another study. Instead, it came from listening to people I trusted.One colleague quietly lost weight on a GLP-1. Another friend told me something more striking: the food noise stopped. Alcohol lost its appeal. Smoking no longer called.That phrase — food noise — suddenly explained decades of struggle.To illustrate, think of sleeping near Lake Shore Drive in Chicago. At first, traffic noise dominates your awareness. Eventually, it fades into the background. Only when you leave the city do you realize how loud it was.Food noise works the same way.When GLP-1 therapy quieted that background signal, eating slowed naturally. Meals ended without effort. Desire changed without rules. Biology shifted.Notably, calories did not lower my stress. Calories did not improve my sleep. Calories did not stop snoring. Biology did.The Unexpected Early BenefitsInterestingly, weight loss was not the first change I noticed.Sleep improved almost immediately. Stress dropped dramatically. Commutes that once registered hours of physiologic stress now barely registered minutes. Appetite normalized. Eating slowed.These changes matter because sleep and stress directly affect inflammation, metabolic health, appetite signaling, and long-term disease risk. In other words, healthspan improved before the scale reflected anything meaningful.That observation alone reframed the entire experience.Why Support Groups Matter More Than Diet RulesAlong the way, something else happened.Friends noticed.Predictably, they asked the same question everyone asks: What diet is working? After I answered honestly, several started their own journeys.Soon enough, we formed an informal support group. People texted. Others called. Questions surfaced: Is this normal? Should I eat this? Does this feeling pass?Support did not mean coaching. Rather, support meant context. Shared experience reduced anxiety. Honest conversations prevented unnecessary panic.Not surprisingly, patterns emerged. People still loved great food. Wine interest decreased naturally. Travel did not end. Joy remained intact.Support mattered because isolation amplifies shame.Vitamins, Bowels, and the Things No One MentionsEqually important, practical realities surfaced.Eating less means needing micronutrients, not fewer of them. Unfortunately, some vitamins fail when appetite drops. In fact, the only time I vomited was after taking a vitamin on an empty stomach. That lesson mirrored decades of bariatric follow-up experience.For me, AG1 worked. No sponsorship exists here. Nevertheless, cost raises questions. With a background in culinary medicine, developing a better formulation makes sense. Thiamine deficiency, for example, causes devastating neurologic consequences. This is not theoretical.Similarly, bowel habits change. Less intake means less output. Fewer bowel movements do not equal constipation. Fiber still matters. Mediterranean-style eating naturally solves most of this problem.Understanding physiology prevents fear.Why I’m Writing Another BookAt some point, frustration turned into obligation.Recently, a physician who has never used a GLP-1 published a book about eating on GLP-1 therapy. That bothered me more than it should have.Given my background — weight-loss surgery, culinary medicine, and lived experience — I realized I had to write this book. Not to sell diets, but to explain reality.The working title?Willpower Is B.S.Subtlety has never been my strength.This book will focus on biology, food ideas, micronutrients, behavior, and healthspan. Above all, it will remove shame from the conversation.Incidentally, my literary agent retired long ago. Therefore, if you know someone who understands medicine, food, and honesty, I’m back in the market.Why the Mediterranean Healthspan Cruise ExistsAt the same time, conversations kept expanding beyond weight loss.Healthspan matters more than thinness. Longevity depends on sleep, stress, nutrition, social connection, and movement. Accordingly, the Mediterranean Healthspan Cruise was born.This is not a weight-loss cruise. Instead, it’s a learning experience. We will discuss food, medicine, science, and aging. Yes, there will be a GLP-1 support session. Equally, there will be conversations for everyone.Learning works best in a community.This Is Only Part OneAs I write this, I’m preparing to inject my 7.5 mg dose of Zepbound. I still hate needles. Some things never change.Nevertheless, this is only part one of the journey.Science progresses when we admit what we got wrong.This time, I listened.ReferencesJastreboff AM, Aronne LJ, Ahmad NN, Wharton S, Connery L, Alves B, Kiyosue A, Zhang S, Liu B, Bunck MC, Stefanski A; SURMOUNT-1 Investigators.

Is Your Watch Predicting Your Death?What Biologic Age Really Means — and What It Doesn’tMy Whoop tells me I’m eight years older than I actually am.Naturally, that raises a question.Does that mean I’m going to die eight years sooner?Is my watch quietly chiseling a new date onto my tombstone?Fortunately, the answer is no.Still, confusion around biologic age has exploded.Wearables promise insight.Apps offer scores.Some even whisper about your future health, as if destiny lives on your wrist.So let’s slow this down and talk about what biologic age really is — and why it matters far less than you think.The Two Numbers and the DashEvery tombstone has two numbers.One marks when you were born.The other marks when you died.However, the most important part isn’t either number.It’s the dash in between.That dash represents your life.It reflects your health, mobility, independence, and curiosity.When we talk about longevity, we shouldn’t obsess over the second number.Instead, we should focus on making those two numbers far apart — and keeping the dash strong for as long as possible.That’s healthspan.Why Biologic Age Sounds Scarier Than It IsBiologic age is not a prophecy.It isn’t a death clock.It doesn’t predict how long you’ll live.Instead, biologic age is a model.It estimates how your body is functioning right now based on things like:resting heart rateheart-rate variabilitysleep duration and consistencyactivity and recovery patternssometimes weight or blood pressureDifferent devices use different inputs.As a result, they often give different answers.In other words, biologic age reflects recent stress and behavior, not your destiny.Think of it as feedback — not fate.Why Your Watch Isn’t Measuring “Real” AgingEarlier in the Fork U longevity series, we talked about telomeres.Those shorten slowly over decades, one cell division at a time.Your wearable isn’t tracking that.Instead, devices like Whoop measure physiology, not DNA.They detect how hard you’ve been living lately, not how much time you have left.A bad week of sleep, travel, stress, or alcohol can push your biologic age higher.A calm, consistent routine can bring it back down.That’s not aging.That’s load management.A Simple Experiment That Tells the Whole StoryHere’s a trick I tried.I told Whoop I was younger than I actually am.Guess what happened?Suddenly, my biological age dropped below my real age.That alone tells you everything.Whoop isn’t predicting where you’re going.It’s comparing how you’re doing relative to the age you told it you are.Once again, that’s feedback — not destiny.Why I Prefer WithingsI use multiple devices because, frankly, I’m a nerd.However, I tend to prefer Withings for one simple reason.They don’t try to scare you.Instead of telling you how old you “really” are, Withings focuses on things that actually improve your life today:blood pressure trendsbody weight and compositionheart rhythmsleep durationlong-term consistencyMore importantly, they ask better questions.Are you sleeping better?Is your blood pressure improving?Are your habits trending in the right direction?That’s medicine.Not numerology.And no — Withings didn’t pay me to say that.The Biggest Mistake People MakeMany people treat biologic age like a grade.Others see it as a moral judgment.When the number drops, they feel virtuous.When it rises, they panic.That framing misses the point.The only question that matters is this:Is it moving in the right direction over time?One bad week doesn’t define you.One good week doesn’t either.Trends matter.Moments don’t.What No Device Can Tell YouNo wearable can tell you:when you’ll diewhether you’ll get cancerif you’ll have a strokehow many years you have leftAnyone claiming otherwise is selling fear — or subscriptions.Technology can guide behavior.It cannot predict destiny.New Year’s Resolutions That Actually Improve HealthspanIf you want to improve your biologic age — and more importantly, your healthspan — start here:Sleep better and more consistently.Build and maintain muscle.Move your body every day.Eat a Mediterranean-style diet.Lower stress where you can.Spend time with people you enjoy.Do those things, and most metrics improve on their own.The Bottom LineYour watch is not your destiny.Chronological age is fixed.Healthspan is not.Biologic age is adjustable, responsive, and reversible.Use it as feedback.Ignore it as prophecy.And remember — the goal isn’t to beat time.The goal is to live well while time keeps moving.ReferencesLevine ME.

GLP-1 Drugs, the Mediterranean Diet, and the Science of Living LongerFor years, anti-aging has been hijacked by supplements, hacks, and promises that never hold up. Meanwhile, real science has quietly moved forward. Today, the most compelling anti-aging story does not come from a powder, a cold plunge, or a fasting app. Instead, it comes from metabolism.A class of medications called GLP-1 receptor agonists started as diabetes drugs. Over time, clinicians discovered something bigger. These medicines now play a major role in obesity treatment, and they produce effects that reach far beyond the scale. Because obesity shortens lifespan and damages nearly every organ system, it makes sense that drugs that treat obesity could also improve healthspan—the years you live with strength, clarity, and independence.However, weight loss alone does not explain what researchers are seeing. These drugs reduce inflammation, protect the heart, lower biological stress, and may even delay cognitive decline. Importantly, many of these effects occur independent of weight loss. That fact has forced scientists to ask a serious question: could GLP-1 drugs represent a new class of anti-aging medicine?Even longevity-focused clinicians, such as Peter Attia, have publicly discussed using GLP-1 drugs at lower doses in select patients—not for weight loss, but for metabolic health and long-term disease prevention.Why Metabolism Matters for AgingAging is not just about time. Instead, it reflects how well your body regulates key systems over decades. Blood sugar control, inflammation, oxidative stress, and cellular repair all shape how fast—or how slowly—you age.GLP-1 receptor agonists influence all these pathways. Originally designed to mimic a gut hormone that signals fullness, these drugs turned out to do much more. Research shows they lower systemic inflammation, improve mitochondrial function, and reduce oxidative stress. As a result, organs function better for longer.In simple terms, when metabolism runs smoothly, cells behave younger.Retatrutide and the Next Generation of GLP-1 DrugsNewer drugs have taken this concept even further. Retatrutide, a triple-agonist medication, targets three hormonal pathways simultaneously: GLP-1, GIP, and glucagon.In Phase 3 trials, participants lost nearly 29% of their body weight, or more than 70 pounds on average. Yet weight loss only tells part of the story. Retatrutide also lowered inflammation, improved blood pressure, improved lipid profiles, and reduced joint pain.Each hormone plays a role. GLP-1 reduces appetite and inflammation. GIP improves insulin sensitivity and nutrient handling. Glucagon increases energy expenditure and fat oxidation. Together, these pathways keep metabolism active, not slowing down during weight loss.That combination does more than shrink waistlines. It restores metabolic flexibility, which declines with age.Inflammation: The Engine of AgingFor decades, scientists blamed aging on simple wear and tear. Modern research tells a different story. Chronic, low-grade inflammation—often called inflammaging—drives many diseases of aging.Heart disease, stroke, arthritis, fatty liver disease, and cognitive decline all share this inflammatory background. In clinical trials, GLP-1 drugs reduced markers such as C-reactive protein, triglycerides, and blood pressure. These changes signal reduced biological aging risk, not just better lab numbers.When inflammation falls, fewer senescent cells accumulate. Blood vessels stay healthier. Organs function longer.Heart Disease and LongevityNothing ages a person faster than a heart attack. Because of that reality, cardiovascular protection matters deeply for longevity.Multiple cardiovascular outcome trials show that GLP-1 receptor agonists reduce major adverse cardiovascular events in people with type 2 diabetes and high cardiovascular risk. Across studies, researchers observed a 13% reduction in cardiovascular death and a 9% reduction in nonfatal heart attacks compared with other treatments.¹²The LEADER trial demonstrated that liraglutide reduced cardiovascular mortality by 22%.⁶ Similar benefits appeared with semaglutide, dulaglutide, and albiglutide.²⁷ Because of this evidence, the FDA approved several GLP-1 drugs for cardiovascular risk reduction in adults with diabetes and established heart disease.⁸These benefits do not come from glucose control alone. GLP-1 drugs lower blood pressure, reduce inflammation, improve endothelial function, decrease oxidative stress, and reduce RAAS activity.³⁴ At the cellular level, they protect heart muscle cells from multiple forms of cell death while enhancing autophagy and mitophagy.⁵Although GLP-1 drugs do not strongly reduce heart failure hospitalizations, meta-analyses suggest a modest benefit.³⁷ Most importantly, they safely reduce atherosclerotic risk. Preventing a heart attack remains one of the most powerful anti-aging interventions available.Dementia: Prevention, Not CureBrain health deserves careful discussion. GLP-1 drugs do not reverse dementia. They do not improve cognition once dementia is established. Recent trials in patients with Alzheimer’s disease showed no meaningful cognitive improvement.That limitation matters.However, prevention tells a different story. Large observational studies show that GLP-1 receptor agonists are associated with 33–45% lower dementia risk compared with other glucose-lowering drugs in people with type 2 diabetes.¹² A 2025 JAMA Neurology study involving nearly 34,000 patients found a 33% lower risk of Alzheimer’s disease and related dementias among GLP-1 users.¹Randomized trial evidence shows a more modest, but still significant effect. A 2025 JAMA Neurology meta-analysis found that GLP-1 drugs reduced dementia risk, while SGLT2 inhibitors did not.³ This finding suggests a class-specific effect, rather than a glucose-only explanation.Mechanistically, GLP-1 drugs reduce neuroinflammation, improve insulin signaling in the brain, promote neurogenesis, and may reduce amyloid-β and tau pathology.⁵⁶ They also improve vascular health, which strongly influences cognitive aging.Age appears to matter. A 2025 target-trial emulation showed weaker effects in adults over 75, but stronger protection in younger patients.⁷ The takeaway remains clear: earlier prevention works better.The goal is not to cure dementia. Instead, the goal is to delay its onset long enough that many people never reach it.Ultra-Processed Food and Brain AgingDiet still matters. Ultra-processed foods damage the same systems that GLP-1 drugs try to repair.These foods hijack dopamine reward pathways, increase cravings, and weaken satiety signals. Soft textures and engineered flavors allow rapid overconsumption. High intake links to higher inflammation, worse metabolic health, reduced gray-matter density, and faster brain aging.Additives and emulsifiers disrupt the gut microbiome and the gut-brain axis. As a result, insulin signaling in the brain worsens. GLP-1 drugs often counteract damage caused by this food environment, but prevention works better than repair.The Mediterranean Diet and AlcoholHere is the empowering part. People can act today.The Mediterranean diet remains the dietary pattern with the strongest evidence for protecting both the heart and the brain. Vegetables, legumes, fruit, whole grains, olive oil, fish, and minimal ultra-processed food form its foundation. This pattern reduces inflammation, improves vascular health, supports the microbiome, and slows cognitive decline.Think of it this way: GLP-1 drugs quiet the metabolic noise. The Mediterranean diet keeps it quiet.Alcohol also matters. Earlier beliefs about alcohol and brain protection did not hold up. Even moderate drinking increases dementia risk, worsens sleep, raises inflammation, and damages the hippocampus. If cognitive protection matters, less alcohol helps, and none works best.What This Means for HealthspanAging is not about adding years. Aging is about protecting systems.GLP-1 drugs support metabolic health. The Mediterranean diet supports biology. Avoiding alcohol protects the brain. Movement and sleep reinforce everything else.If heart disease, dementia, and disability are delayed long enough, many people will never experience them. That outcome does not represent immortality. Instead, it represents success at healthspan.ReferencesUssher JR, Drucker DJ. Glucagon-Like Peptide 1 Receptor Agonists: Cardiovascular Benefits and Mechanisms of Action.

The Holiday Party That Turned DeadlyIt started at a holiday party.Laughter, champagne, a toast — then a collapse.A fifty-two-year-old, active and healthy, suddenly lost consciousness.Paramedics did CPR and shocked her heart twice.She survived — barely.Doctors called it Holiday Heart Syndrome: an alcohol-triggered arrhythmia that can kill.​What Is Holiday Heart?Holiday Heart arises after binge or even moderate drinking, especially around celebrations. Alcohol irritates heart cells, disrupts electrolytes, and scrambles electrical signals, which can trigger atrial fibrillation — an erratic rhythm that raises the risk of clots, stroke, and sudden death. Even a single heavy night can set it off, and repeated use amplifies inflammation and structural damage long after the hangover fades.​Alcohol and Your HeartFor years, the “French paradox” suggested red wine protects the heart, but newer evidence points instead to lifestyle patterns rather than wine itself. Ethanol and its metabolite acetaldehyde directly injure heart muscle, disturb calcium handling, damage mitochondria, and can lead to Alcoholic Cardiomyopathy — an enlarged, weakened heart. Harm shows up even in relatively low intake, and improvement typically requires reducing or stopping alcohol.​Alcohol and CancerAlcohol is a proven carcinogen that promotes DNA damage, inflammation, oxidative stress, and hormonal shifts that favor tumor growth. At least seven cancers — including those of the mouth, throat, larynx, esophagus, liver, colon, and breast — are directly linked to alcohol, with risk beginning above zero and rising with each additional drink. Even up to one drink a day meaningfully increases breast cancer risk, and the combined use of alcohol and tobacco multiplies risk even further.​Blue Zones, Not Blue WineYou’ve probably heard this one:People in Sardinia or Ikaria drink wine every night and live to 100.What’s missing is the math.They sip 3 to 4 ounces — not a glass, not a typical American glass, but a tasting. The flight of wine.Their rustic wines are 10–11 percent alcohol, not the 16 percent bombs from Sonoma.And they don’t live long because of the wine.They live long because of everything else:walking hills, eating beans, taking naps, sleeping well, and belonging to a community.Their wine is cultural, not clinical.If you want their healthspan, copy their diet, movement, and purpose — not the nightly pour.Weight, Metabolism, and AgingAlcohol hijacks metabolism by forcing the liver to prioritize ethanol breakdown, pushing fat and sugar processing aside. Drinks can add substantial hidden calories, promote fatty liver, and stall fat loss, even when the rest of a diet looks reasonable.​Why “Detox” Fixes FailPopular “alcohol detox” supplements promise faster clearance or hangover prevention, but research points to ethanol itself and the inflammatory response as the main drivers of symptoms. Blocking acetaldehyde alone does not prevent mitochondrial damage, immune activation, or the residual effects that follow a night of heavy drinking.​The Longevity HypocrisyModern wellness culture often warns about “toxins” while normalizing regular drinking, even framing certain spirits or wines as health tools. Yet, when viewed through a longevity lens, alcohol stands out as one of the most potent, fully optional biological stressors in the modern lifestyle.​When You StopOnce drinking stops or drops sharply, the body begins to repair: blood pressure often falls within days, heart rhythm and sleep tend to improve within weeks, and liver fat can regress over subsequent months. Over years, cancer and cardiovascular risks decline, with former light-to-moderate drinkers gradually approaching the risk profile of people who never drank or who stopped earlier in life.​Bottom LineAlcohol is deeply woven into culture and celebration, but it is neither a health food nor a longevity strategy. For anyone serious about healthspan, cutting alcohol is one of the simplest, highest-impact levers available — a change your heart, DNA, and future self are strongly likely to benefit from.​ReferencesBerger D, De Aquino J P, Charness M E, et al.

Muscle is Medicine: Why Lifting Weights is Your Best Longevity InvestmentClearly, your body changes as you age. I learned this lesson years ago when my son was three years old. We started him skiing, and he loved every minute of it. When he fell, he tumbled onto his behind, jumped right back up, and skied down the hill like nothing had happened. He was pure rubber and resilience.However, I was 53 years his senior that year. I did an inadvertent 360-degree twirl on the slopes myself. His mother saw me and immediately asked if I had broken my wrist, wondering when I could return to surgery. The difference between a flexible young body and an older body is critical. Consequently, I retired from skiing that season and now enjoy the lodge, where I write and make them great dinners.Indeed, your older body desperately needs work to stay flexible, strong, and balanced as time goes on. I have seen too many independent seniors lose everything after a simple fall in their own home. They go from living on their own to spending their last days in a care center, sometimes never leaving bed. This outcome is not healthspan. Instead, you want a fall to be like my son’s—just on your butt and back up. Sadly, too many fall and cannot get up. This isn't a commercial for a safety pendant, but a sincere plea for you to start working your muscles.Section 1: The Enemy is Muscle Loss (Sarcopenia)Specifically, we talk frequently about heart health and clear arteries in longevity. Those things are unquestionably crucial. Nevertheless, the biggest threat to functional independence as we age is a condition called sarcopenia. This is the medical term for age-related muscle loss.Unfortunately, we start losing about 3 to 8 percent of our muscle mass every decade after age 30. That loss accelerates quickly once you hit 70. This problem is not just about looking less toned; fundamentally, it is about losing the ability to stand up from a chair, carry groceries, or, most importantly, catch yourself when you trip. The falls that result are often catastrophic.Section 2: Big Things Help Small Things—The Cellular ConnectionAmazingly, resistance training is effective at the microscopic level, too. We have talked extensively about the tiny, complex mechanisms of the cell, but here is the key takeaway: small things benefit from big things.In fact, increasing muscle mass through training has direct, positive effects on two major microscopic drivers of aging: mitochondrial function and telomere health.To elaborate, when you challenge your muscles, you signal your cells to create more energy. This signal forces your mitochondria—the cellular powerhouses—to become both more numerous and more efficient. Better mitochondrial function equals more energy and less cellular stress.Moreover, studies show that resistance training actually increases the activity of the enzyme telomerase in some cells. Telomerase helps maintain the protective caps on your DNA called telomeres.Therefore, you don’t need to buy fancy, expensive supplements like NAD or telomere boosters. Picking up a dumbbell costs less money but yields more results. You gain muscular strength, better metabolism, stronger bones, and the cellular benefits all at once.Section 3: Muscle is Your Metabolic PowerhouseLet's consider how muscle mass influences your diet. Your muscle is actually your body’s largest organ for glucose disposal. Think of it like this: when you eat, your body releases glucose (sugar) into your bloodstream. Insulin then works to escort that glucose out of your blood and into your cells for energy. The vast majority of that glucose gets parked in your muscle cells.Clearly, if you have more muscle mass, you automatically have a bigger parking lot for that glucose.Consequently, more muscle means your body gains better insulin sensitivity. It becomes more efficient at regulating blood sugar. This effect is the absolute bedrock of preventing and managing Type 2 diabetes. Ultimately, resistance training is a powerful pharmaceutical intervention for your metabolic health.Section 4: Building an Iron SkeletonHowever, the benefits don't stop at the muscles. Let's talk about bone density, which is crucial for everyone, especially women. We know calcium and Vitamin D are important, yet they are only one part of the solution.Remember that bone is living tissue; it responds to stress. When you lift a weight—even if it is just your own body weight in a squat—the mechanical force signals to your bones that they must get stronger. This process is known as the Mechanostat principle. Conversely, without that heavy, high-intensity mechanical load, bone density naturally declines, leading to osteoporosis.In conclusion, if you only do low-impact cardio, you are helping your heart, but you are not sending the signal needed to maintain or increase bone mineral density. Specifically, you must load your bones to strengthen them.Section 5: The Importance of Balance and Quality CoachingBeyond pure strength, true independence depends on mobility and balance. This is where functional training, including Yoga, plays a huge role. My favorite Yoga classes are a combination of bodyweight resistance and cardiovascular movement. I look for the physics—the movement, the resistance, and the balance—and keep the "woo" out of it. Furthermore, a Yoga mat costs far less than some supplements, but it will make a fall much easier to recover from.Therefore, if you are getting started, please get professional help! Having a great gym coach to help with proper form is paramount—shout out to my friends Jeremy the Hulk and the Zeigler Monster! Additionally, it is equally important to enlist a private Yoga instructor to ensure you are not malaligned and that you know what to look for. A special shout-out to my yogi Xuan—and yes, I will be doing more classes this year!Section 6: The Ultimate Goal: Getting Back UpUltimately, the reason we train is not just to be strong; rather, it is so that if you fall when you are 65, 75, or 80, you possess the strength, stability, and awareness to get up by yourself. This ability is the true mark of functional longevity.Let me give you two examples of why this ability matters so much. A fellow was admitted to a facility after he broke his hip. Before he fell, he lived alone, was a champion bowler, and enjoyed his life. He simply slipped on a rug, fell, and was found a day later. After his hip was fixed, he spent the next year of his life mostly in bed, eventually dying of COVID-19 in a long-term care facility. One single fall that he couldn't get up from changed his life and his outlook completely.Contrast that with my own dad. He took a fall at age 96 trying to trim a tree. It took a bit of effort, and he received a stern warning from his son and the EMTs, but he got up. He lived independently until age 98.Consequently, this kind of preparation matters because the statistics are sobering: falls are the leading cause of injury death for people over 65. Tragically, studies show that up to 30% of seniors who fracture a hip lose their independence entirely.Conclusion and Call to ActionFinally, resistance training, combined with functional movement, is the macroscopic lever that pulls all those microscopic switches. It is the closest thing to a fountain of youth that doesn’t require a prescription. It just requires effort.Remember that you must continually increase the demand on your body—this is called progressive overload. Most importantly, remember that resistance training is the stimulus, but protein is the building material. Aim for a high protein intake daily, and definitely enjoy that protein smoothie right after your workout!On that note, we’re even taking this training on the road this year with our Mediterranean Cruise, where we’ll have an instructor to help you with simple movements—things so that if you fall, you can get up by yourself.ReferencesDao T, Green AE, Kim YA, Bae SJ, Ha KT, Gariani K, Lee MR, Menzies KJ, Ryu D.

🧬 Telomeres and Time: Can We Really Rewind Aging?The Lowest Hemoglobin I’ve Ever SeenThe lowest hemoglobin I’ve ever seen belonged to a young woman who was still standing. Her blood count was one-fourth of normal. She was pale, short of breath, and strong enough to walk into the clinic.Doctors soon learned her bone marrow had stopped making new blood cells. The diagnosis was aplastic anemia — a true telomere disease.She survived thanks to her fitness, modern science, and a bone marrow transplant from a generous donor in Germany. Two years later, she’s in law school, healthy, and full of life.What Are Telomeres?Each cell in your body carries chromosomes — long strands of DNA. At the ends of those chromosomes sit telomeres, tiny caps that keep the DNA from unraveling, like plastic tips on shoelaces.Every time a cell divides, its telomeres shorten a little. When they get too short, the cell can no longer divide. Scientists call that stage cellular senescence — cellular retirement.In 2009, researchers Elizabeth Blackburn and Carol Greider won the Nobel Prize for discovering telomerase, an enzyme that can rebuild telomeres. Their discovery sparked dreams of reversing aging. But there’s a catch: cancer cells also use telomerase to live forever. Turning that enzyme on everywhere might turn back time — or turn on tumors.Why Everyone Talks About TelomeresTelomeres became the poster child for longevity marketing.Social media ads promise to “measure your biological age.” Supplement companies claim to “lengthen your telomeres” for hundreds of dollars a bottle.The problem? Telomere tests vary between labs. Results can change by 20 percent depending on the method. They show trends, not destiny.What’s Being StudiedReal scientists are studying how telomeres behave under different conditions.Danazol — a synthetic sex hormone that slows telomere loss in people with inherited marrow failure. It works but brings side effects, so it’s not an anti-aging trick.Henagliflozin — a diabetes drug that increased telomere length in one small study. Whether that helps humans live longer is still unknown.Aripiprazole — an antipsychotic that repaired telomeres in cells after oxidative stress. That’s a Petri dish result, not a prescription for youth.These drugs show that we can nudge biology, but they’re for disease, not for vanity.Vitamins and Compounds That Might HelpNutrients influence telomere health, too.Vitamin D supports telomerase. Long-term studies show it slows telomere shortening.Vitamins C and E help reduce chemical stress that wears telomeres down.Gamma-tocotrienol, a form of vitamin E, may reverse telomere loss — so far only in lab work.TA-65, from the Astragalus plant, may activate telomerase but carries risk. Turning on telomerase could also fuel cancer.Telomir 1 is experimental and not available outside research.None of these is proven to extend life. They’re promising ingredients, not miracles in a capsule.What Lifestyle Still Beats EverythingLifestyle matters more than any supplement.A large study at UCSF showed that people who ate a Mediterranean diet, exercised, and managed stress boosted telomerase activity within months.No powder required.Telomeres respond to care. They’re markers of how you live, not the cause of how long you live.Longer telomeres don’t guarantee longer life — they reflect how your body has handled time, inflammation, and stress.What Scientists Agree OnResearch tells a simple story:Telomeres shorten as cells divide.Stress, smoking, and inflammation speed that process.Healthy diets and regular movement slow it.Some medications affect telomere biology but aren’t for general use.We still don’t know if lengthening telomeres increases lifespan.So far, no pill or powder beats sleep, exercise, and plants on a plate.The Real TakeawayTelomeres aren’t countdown clocks. They’re mileage markers.Protect them by doing the basics well: eat plants and fish, move daily, sleep enough, manage stress, and don’t smoke.Simple. Sustainable. Supported by science.ReferencesCalado RT, Young NS. Telomere Diseases. N Engl J Med. 2009;361(24):2353-65. PMCID: PMC3401586Lai T-P, Wright WE, Shay JW. Techniques for Assessing Telomere Length.

The Mitochondria Problem: Why These Tiny Powerhouses Shape How We AgeMany people suddenly talk about mitochondria. You hear them in political speeches, on podcasts, and across social media. RFK Jr said he can “see” kids with weak mitochondria just by watching them walk through an airport. Others claim special diets or powders can “fix” aging by supercharging these organelles.However, most of that chatter misses the actual science.This post breaks down what mitochondria do, why they matter for aging, and how you can keep them healthy. No hype. No detox teas. Just biology you can use.What Are Mitochondria?Every cell in your body contains tiny structures called mitochondria. They act like miniature cells living inside your larger cells. Each mitochondrion even has its own DNA.Mitochondria divide independently from your regular cells.They manage your energy, converting glucose to ATPFinally, mitochondria keep your organs working.You inherit all your mitochondria from your mother, which is why scientists use mitochondrial DNA to trace ancestry.How Did We Get Mitochondria? (A Very Old Story)About 1.5 billion years ago, a simple cell swallowed a bacterium and refused to digest it. Instead, they formed a partnership.The bacterium supplied energy.The host cell provided safety.That partnership became the mitochondrion. Every person alive today runs on that ancient deal.What Do Mitochondria Do All Day? Mitochondria take glucose from your food and convert it into ATP — the energy your body uses to move, think, heal, and grow. This process runs every second of your life.You cannot swallow ATP and get more energy. ATP supplements don’t work. Only your mitochondria make the usable fuel your body needs.Why Young Mitochondria Work So WellYoung mitochondria act like teenagers. They run fast, bounce back quickly, and handle stress with ease. Cells constantly recycle old mitochondria through a process called mitophagy. This system works beautifully in childhood.Fresh mitochondria power:strong musclessharp thinkingfast recoveryhealthy metabolismWhen mitophagy runs smoothly, you feel energetic and resilient.What Happens When Mitochondria AgeAging slows everything down. Mitochondria begin to leak more “exhaust,” build up mutations, and lose efficiency. Damaged ones don’t get removed as well, because mitophagy weakens with age.Unfortunately, mitochondria do something worse than slow down:They fuse with healthy mitochondria.Imagine pouring spoiled milk into a fresh gallon. The whole jug goes bad. Aging mitochondria do the same thing inside your cells. They spread dysfunction to the healthy ones.How Aging Mitochondria Cause TroubleAs mitochondria fail, they change how cells function. They send distress signals back to the nucleus that alter gene expression. These messages push cells toward inflammation, stress, and survival pathways that your body normally keeps quiet.Even more concerning, changes in mitochondrial shape — too much splitting (fission) and not enough merging (fusion) — appear in both aging and cancer. These shifts support tumor growth, help cancer cells spread, and make some treatments less effective.Aging mitochondria increase the risk of:brain fogmuscle fatigueslower recoveryheart strainmetabolic slowdowncancer-friendly environmentsMitochondria sit at the center of how we age.Why “Mitochondrial Booster” Supplements Miss the MarkPlenty of supplements promise to “repair” mitochondria. Many sound exciting:NAD boostersUrolithin Apeptidesantioxidant stacksHowever, evidence in actual humans remains limited.NAD boosters don’t show meaningful anti-aging benefits.Urolithin A can help with muscle endurance, but doesn’t reverse aging.Antioxidant megadoses may even interfere with exercise benefits.People want a miracle switch. We don’t have one.What Does Improve Mitochondrial HealthGood news: the basics still win. And they outperform supplements every time.1. Resistance TrainingYour muscles grow new mitochondria in response to lifting weights or doing body-weight exercises.2. Zone 2 ExerciseThis “comfortably challenging” aerobic zone trains your body to use oxygen better. You can talk, but you can’t sing.3. SleepYour body repairs mitochondrial damage at night. Poor sleep means poor repair.4. Mediterranean DietWhole foods, plants, nuts, fish, and olive oil protect mitochondria from inflammation and stress.5. Treating Metabolic Disease EarlyHigh blood sugar, high LDL, and high blood pressure destroy mitochondria faster than anything else.Why Diet Tribes Get Mitochondria WrongSome diet influencers insist that insulin resistance is the One True Cause of aging and that keto or carnivore diets fix it all. That was tested in high-quality metabolic ward studies.It failed.Low-carb diets did not outperform other diets when calories and protein were controlled. Fat loss was the same. Metabolism behaved the same. Insulin wasn’t the magic dial.Mediterranean-style eating continues to show the strongest data for longevity.Alcohol Ages Mitochondria FastYour liver breaks down alcohol by generating large amounts of oxidative stress. That stress directly damages mitochondrial DNA, mitochondrial enzymes, and mitochondrial membranes.It also disrupts their normal fuse-and-divide rhythm, which accelerates aging inside your cells. The hangover fades, but the mitochondrial damage does not.Bringing It All TogetherMitochondria are real, essential organelles — not a buzzword. Yet some people use the term “mitochondria” the same way Deepak Chopra uses the word “quantum": to describe everything and explain nothing.Here’s the truth:When mitochondria age, you age.Driving inflammation.Increasing cancer risk.Slowing your metabolism.They weaken your heart and muscles.Finally, they cloud your thinking.If we’re going to blame mitochondria for aging, let’s at least understand them — and learn how to keep them healthy.Strength training, aerobic exercise, sleep, nutrition, and treating metabolic disease remain the most powerful tools we have.Your mitochondria are trying their best.Help them do their job.REFERENCES1.Somatic Mutations of Mitochondrial DNA in Aging and Cancer Progression.Lee HC, Chang CM, Chi CW.

Urolithin A: What It Is, How It Works, and Why Your Gut Decides EverythingBy Dr. Terry SimpsonMost people hear the name Urolithin A and think it belongs in a commercial about prostate health. It sounds like something a man named “Gary, 62,” would talk about while fishing. But Urolithin A has nothing to do with plumbing. Instead, it sits at the center of a new wave of longevity science focused on how our cells clean up old, broken parts.As we age, our mitochondria—the tiny power centers inside our cells—start to slow down. They build up damage and stop working well. Eventually, this pile-up makes us lose strength and energy. That’s where Urolithin A comes in. It helps switch back on a process called mitophagy, which is basically the cell’s recycling program for old mitochondria.Where Urolithin A Really Comes FromYou cannot eat Urolithin A directly. Instead, your body makes it when your gut bacteria break down special plant compounds called ellagitannins. These are found in foods like:pomegranateswalnutsberriesgreen tea (yes, really)Green tea is usually known for its catechins, but it also contains ellagitannins like strictinin. After you drink it, your gut bacteria break these tannins apart and create ellagic acid, which can later turn into Urolithin A.However, this only works if you have the right microbes. And here’s the surprising part:Most people do not.Studies show that only 12% to 40% of adults naturally produce Urolithin A from food. Everyone else makes little to none because their gut bacteria simply aren’t built for the job.How Your Gut Decides EverythingYour microbiome—the community of bacteria living in your digestive system—decides whether you make Urolithin A or not.People who produce Urolithin A usually have:more diverse gut microbesspecial bacteria like Enterocloster and Gordonibacterthe right genes inside those microbes to do the chemical conversionPeople who don’t produce it (called “metabotype zero”) lack those bacteria or the gene pathways needed. Eating more pomegranates or drinking more green tea does not fix this. No diet, including keto or Mediterranean, has been shown to turn a non-producer into a producer.This is why two people can eat the same food, and only one makes Urolithin A.What Urolithin A Does in HumansIn older adults, researchers have tested Urolithin A supplements for up to 4 months. These studies show several encouraging results:muscle endurance improvesinflammation markers decreasemitochondrial health markers look betterEven so, there are limits. Trials show no meaningful improvement in:walking distanceATP (cellular energy) productionoverall physical functionSo the biology looks better, but major clinical outcomes have not changed.What Happens in the Lab (But Not Yet in Humans)Scientists also study Urolithin A in senescent cells—cells that have stopped dividing but still cause inflammation. In the lab, Urolithin A can:reduce senescence markerscalm inflammatory signalsrestore mitophagyimprove oxidative stresseven strengthen circadian rhythms inside aging cellsAll of this sounds exciting. However, these findings are from cell culture, not humans. They give us clues, not guarantees.Food vs SupplementsYou cannot get Urolithin A directly from food. You only get the precursors, and only people with the right gut bacteria turn those precursors into Urolithin A.Supplements bypass the microbiome entirely and give everyone measurable Urolithin A, even non-producers.Foods that contain ellagitannins include:pomegranateswalnutsraspberriesblackberriessome teas, especially green teaBut none of these will raise Urolithin A levels if your gut bacteria cannot perform the conversion.Is Urolithin A Safe?Short-term human studies show that Urolithin A is safe and well-tolerated. Most people experience no side effects. When side effects do show up, they are usually mild digestive symptoms like bloating or softer stools.What we don’t know:long-term safetypregnancy or breastfeeding safetymulti-year useeffects in chronic diseaseIn other words, the short-term data look good, but the long-term story hasn’t been written yet.Should You Take It?Here is the simple answer:Urolithin A is biologically promising but clinically modest.It improves certain cellular markers and may boost muscle endurance in older adults.It does not reverse aging or change major health outcomes—not yet.Supplements make the most sense for:adults over 60people with early muscle lossindividuals who are non-producersthose wanting to support mitochondrial healthBut nothing replaces the basics:resistance trainingmovementeating wellsleepstress controlThat is still the foundation of a longer, healthier life.REFERENCES(For the blog — as provided)Kuerec AH, Lim XK, Khoo AL, et al.

🧬 NAD: The Molecule of Life — and the HypeHow a lab coenzyme became the latest anti-aging obsessionWhat We Mean by Longevity and HealthspanWhen people talk about longevity, they usually mean how long we live.But healthspan — the years we live well — matters far more.That’s the time before disease steals our energy, mobility, and independence.Modern medicine has already doubled our lifespan in the last century.Now the goal is to extend the healthy part — without falling for pseudoscience along the way.When Marketing Meets MedicineLongevity has become a booming business.Some gurus, like Dr. Eric Topol, do real science.Others, like Peter Attia, sell access: $150 000 per patient for lab tests, a VO₂ max treadmill run, and a few “optimized” workouts.He’s also an investor in AG1 — the influencer’s green drink of choice.Andrew Huberman promotes similar ideas under studio lights bright enough to sterilize a petri dish.Both are clever, credentialed, and caught between data and drama.Then there’s Dr. David Sinclair, who helped discover how cells age — and then helped turn that discovery into a supplement empire.His company tried to patent NMN, an NAD precursor, as a drug.The FDA briefly removed NMN from the supplement market, sending Reddit into meltdown.It’s back now, but the episode showed how quickly science slides into sales.And finally, we have the shirtless salesmen:Paul Saladino, who went from carnivore crusader to “fruit influencer.”Liver King, whose real secret wasn’t liver — it was injectable.And Gary Brecka, who claims to predict your death date (for a fee).These are subscription services disguised as sages.What NAD Actually IsNicotinamide adenine dinucleotide (NAD⁺) is a molecule found in every living cell.It helps convert food into energy and repair DNA.As we age, NAD levels fall — metabolism slows and damage builds up.So scientists asked: If we raise NAD again, can we slow aging?In mice, the answer looks promising.NAD precursors like nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) increase average lifespan by 5–15 percent and improve energy, insulin sensitivity, and activity.That’s great for mice — but we don’t live in cages or eat lab chow.Can You Get NAD from Food?Not directly — but your body makes NAD from dietary precursors:tryptophan and niacin (vitamin B₃).You’ll find them in fish, poultry, beans, milk, and whole grains — basically, a Mediterranean-style diet.So before spending $90 on capsules, you can spend $9 at the farmers' market.What the Human Studies ShowHuman trials of NR or NMN (usually 500–2000 mg per day for 6–12 weeks) show they are safe and well-tolerated.They modestly raise NAD levels and sometimes improve lipid profiles and blood pressure.But the effects are small and inconsistent, especially in healthy adults.NAD precursors do not reverse aging.They don’t prevent heart attacks or extend lifespan in people — at least, not yet.NAD vs Statins: A Reality CheckMeta-analyses show NAD precursors, especially niacin, can lower LDL (“bad”) cholesterol by about 8–12 percent.That’s fine, but compare it to rosuvastatin (Crestor):DoseAverage LDL Reduction5 mg≈ 45 %10 mg≈ 52 %20 mg≈ 55 %40 mg≈ 63 %That’s the difference between “interesting biochemistry” and “fewer funerals.”So NAD may nudge your cholesterol; statins save lives.Who Might BenefitOlder adults with metabolic syndrome, prediabetes, or early neurodegenerative disease could see modest improvements in inflammation or blood lipids.Younger, healthier people mostly see lighter wallets.No serious drug interactions have been documented, though theoretical ones exist with some chemotherapy or DNA-repair drugs.As always, talk to your doctor before combining anything with prescription therapy.Food Before PharmaThe best way to support NAD and longevity is still food, sleep, and movement.A Mediterranean diet rich in legumes, vegetables, olive oil, and fish fuels NAD pathways naturally — and has proven benefits for heart and brain health.No influencer code required.A Note from the GalleyWe’ll explore all of this — diet, longevity, and a little wine science — on next summer’s Mediterranean Longevity Cruise.World-class physicians, scientists, and chefs will join me for ten days of evidence-based indulgence.It’ll cost less than a Peter Attia consult — and no one will force you to drink AG1.(For the record, I still do. It’s gentle on my stomach, but I’m hunting for less bougie vitamins.)The TakeawayBoosting NAD may someday help extend healthspan, but for now, the best evidence still supports:Eat Mediterranean-style food.Move daily.Sleep enough.Manage stress.See your doctor before your supplement dealer.That’s how you live longer and better — no silver bullet, just science and common sense.ReferencesEffects of NAD+ Precursor Supplementation on Glucose and Lipid Metabolism in Humans: A Meta-Analysis.

🎙 Celebrating 100 Episodes of Science, Sanity, and a Little SarcasmThis is it — our 100th episode of FORK U.Over the last hundred episodes, we’ve gone from goat-gland hucksters to the microbiome, from Kellogg’s enemas to cholesterol chemistry, and from Blue Zones to bird flu.Today, we look back — not just to celebrate the great scientists who shaped modern medicine, but to expose the modern influencers who sell that same science back to you in a bottle.Welcome to The FORK U Hall of Fame and Shame.🧠 The Hall of Fame🩺 Dr. Ancel Keys — The Misunderstood ScientistDr. Ancel Keys didn’t make guesses — he made measurements.He and his team built one of the most detailed long-term studies in the history of medicine.They went village by village across seven countries.They collected what people ate, sent food samples back to labs, recorded EKGs, drew blood, and reviewed medical charts — not for a few months, but for decades.That’s what science looks like: patient, precise, persistent.Critics like Gary Taubes claim Keys “left out countries.”That’s false — and it only proves they never read his work.Keys studied cohorts of men within small villages, followed them carefully over the years to learn how diet and disease connected.Without today’s molecular tools, he still discovered the pattern that modern science later confirmed:ApoB — the protein attached to LDL cholesterol — is transported into the arterial wall, starting the process of atherosclerosis.Keys didn’t chase fame. He chased truth.His data became the foundation of preventive cardiology.If you want to honor him, drizzle olive oil instead of conspiracy.And a personal note — my thanks to Dr. Harry Blackburn, who worked with Keys and has kindly shared insights from those pioneering days.💉 Dr. Frederick Banting and Charles Best — The Children Who Woke UpIn 1922, Banting and Best discovered insulin.Before that, children with diabetes slipped into comas and died.After the first injections, they woke up.Their parents fed them well, but diet alone couldn’t save them.Good science did.It was one of medicine’s greatest moments — and still saves lives every day.🧬 Dr. Kanehiro Takaki — The First VitaminBefore anyone even knew the word vitamin, Japanese surgeon Dr. Kanehiro Takaki saw sailors dying from beriberi.Using early ideas of epidemiology, he realized the problem wasn’t infection but nutrition.He changed their diet — adding barley and vegetables — and the disease vanished.Takaki brought Japan into modern medicine.Even Dr. Charles Mayo admired him.Had he lived longer, he would likely have shared a Nobel Prize.🧫 Dr. Leonard Hayflick — The Original Longevity DoctorIn 1961, Dr. Leonard Hayflick discovered something remarkable:Human cells divide about fifty times, then stop — the Hayflick Limit.He proved aging isn’t mystical. It’s biological.Every division shortens a cell’s life clock until it retires.His research wasn’t about nutrition, but it changed everything about how we understand aging and regeneration.He was the first true longevity doctor — without supplements, slogans, or selfies.❤️ The DASH and Portfolio Diet TeamsThe DASH Diet — Dietary Approaches to Stop Hypertension — came from a dream team of researchers.Dr. Lawrence Appel at Johns Hopkins led the NIH trial.Drs. George Bray, Donna Ryan, and Catherine Champagne built the menu at Pennington Biomedical.Dr. Frank Sacks at Harvard analyzed the data.They showed that a diet rich in fruits, vegetables, and low-fat dairy could lower blood pressure without weight loss.Then came the Portfolio Diet, developed by Dr. David Jenkins and his team at the University of Toronto.They combined soy, nuts, soluble fiber, and plant sterols — lowering LDL cholesterol by up to 17 percent.That’s culinary medicine — research that feeds both the lab and the kitchen.And yet some influencers still say we need “more salt.”The DASH team proved the opposite — unless, of course, you’re selling $39 mango-flavored electrolytes on TikTok.🩻 Edinburgh — Where Surgery Became ScienceIf you ever visit Edinburgh, skip the castle and go straight to the Surgeons’ Hall Museum.Inside are the breakthroughs that transformed surgery:Lister’s antisepsis, Syme’s anatomy, and James Young Simpson’s chloroform.It was here that Arthur Conan Doyle, as a medical student, learned from Dr. Joseph Bell, the sharp observer who inspired Sherlock Holmes.From those halls, medicine shifted from superstition to study — from anecdote to anatomy.It’s where modern diagnosis began.And this month on TikTok, we’ll walk those halls together.🚫 The Hall of Shame🧬 Gary Brecka — The Biohacking HypemanEvery generation gets its snake-oil salesman; ours just live-streams.Gary Brecka calls himself a biologist who can predict your date of death — and change it for a price.He has no medical degree, just a bachelor’s in biology and a borrowed pair of scrubs.He never finished chiropractic school.He sells hydrogen-water bottles, claiming there are 1,400 studies — there aren’t.He says cold plunges melt fat — they don’t.If they did, every Alaskan fisherman would look like Thor.Brecka’s not a scientist. He’s a salesman with a ring light.🧑‍⚕️ Barbara O’Neill — The Preacher, Not the ProfessorBarbara O’Neill preaches more than she practices science.She claims cayenne pepper stops heart attacks and cholesterol is a Big Pharma hoax.She charges thousands for seminars, dismisses evidence, and wraps it all in Seventh-Day Adventist fervor.Meanwhile, my Crestor costs $2.36 for three months.You do the math.🧴 The Supplement InfluencersNow for the shirtless side of pseudoscience.Compare the scientists who built the Mediterranean, DASH, and Portfolio diets to today’s supplement influencers.The difference? The scientists do science. The influencers do sales.There’s Paul Saladino — the carnivore who rediscovered fruit when steak stopped trending.The salt bros selling electrolyte powder at $39 a bag.Dr. Gundry, the ex-surgeon who says beans are dangerous — unless you buy his Bean Guard for $60 a month.And the Liver King — whose biggest muscle came from a syringe, not a steak.They don’t test ideas — they test lighting.They make millions selling powders, not progress.Science doesn’t need an affiliate link.🩺 The Real HeroesWhile the supplement crowd surfed and sold, real heroes — doctors, nurses, respiratory therapists, and dietitians — showed up every day during the pandemic.Before there was a vaccine.Before there was safety.They went anyway.Those are the people who save lives — not the ones selling shortcuts.🔬 Building the BridgeAfter 100 episodes, one truth stands out:Science doesn’t need to be sexy to save lives.My job — our job — is to build the bridge between real scientists and the public.My background is in medicine, but my mission is communication.To bring you work done in labs and clinics — not under ring lights.The people I feature here aren’t influencers.They’re the scientists whose glory comes from a colleague’s handshake, not a sales link.Because behind every breakthrough is someone who’ll never trend on TikTok — but they’re the ones who truly change the world.That’s what FORK U stands for — separating noise from nutrition, hype from health, and always choosing evidence over ego.

Thanksgiving is more than a meal — it’s a worldwide celebration of gratitude built around foods that started here in the Americas. Corn, beans, potatoes, and turkey didn’t just feed a nation; they changed global cuisine. Today, we blend culinary history with medical sense to show how to enjoy the feast without the nap.🍁 A Holiday for the WorldOur Canadian friends already finished their celebration. For their Thanksgiving, I roasted a chicken with Swiss Chalet sauce — if you know, you know. Thank you, Canada, for giving us Tim Hortons, Swiss Chalet, and the perfect excuse for early gravy season.In the United States, we wait for the fourth Thursday in November to celebrate. And while Thanksgiving began as a survival story between settlers and Native Americans, it’s become a global holiday. Whether you’re in Edinburgh, London, or Los Angeles, if there’s a turkey on your table, you’re part of it.🦃 The Turkey TruthTurkey is a ridiculously large bird. Cooking one whole is like putting a cow in the oven and hoping all the parts turn out right — it just doesn’t work.That’s why I separate mine. The breast goes into a sous vide bath until juicy and tender, and the legs roast separately until golden brown. This approach keeps everyone happy and the meat perfectly cooked.Another reason to love turkey: it’s naturally low in saturated fat, especially compared to red meat. So, when prepared well, it’s one of the healthiest centerpieces for your table.🥖 Cornbread Stuffing — Cook It SafelyStuffing the bird might seem traditional, but it can also be dangerous. Baking bread inside raw poultry turns your dinner into a bacteria incubator. Instead, bake it separately.My favorite? Cornbread stuffing — a true dish of the Americas. Combine cornbread cubes, sautéed onions, celery, herbs, mushrooms, and broth. For extra flavor, crisp up some turkey skin like “poultry bacon” and crumble it on top.(You’ll find the full recipe at terrysimpson.com)🥔 Potatoes — From the Andes to Every PlateLong before Europeans knew what a potato was, Indigenous farmers in the Andes were cultivating hundreds of varieties. Those humble tubers crossed the ocean and reshaped diets from Dublin to Delhi. Yes, the Italians perfected Gnochi - and the Irish love of the potato brought many of our finest folks to the United States.At my table, I keep mashed potatoes simple — Yukon Golds, butter, olive oil, milk, salt, and pepper. No truffle oil. No mountain of bacon. Just creamy, honest comfort food.🥗 Green Beans and the Three SistersGreen beans are another gift from the Americas. Native farmers grew them with corn and squash — the Three Sisters that nourished generations. The beans climbed the corn stalks while enriching the soil — the original regenerative farming.In Culinary Medicine, we love beans for their fiber, plant protein, and heart-healthy nutrients.If you’re remaking the classic green bean casserole, skip the canned soup. Use fresh mushrooms, milk, and a touch of cornstarch. Or, sauté the beans in olive oil and garlic for a lighter, Mediterranean twist.(Full recipe posted at terrysimpson.com)🥣 Cowboy Caviar — A Smart StarterBefore the main event, try Cowboy Caviar — a colorful bean salad from the American Southwest. It’s bright, high in fiber, and helps you eat more slowly (and more sanely).Mix black beans, black-eyed peas, corn, peppers, red onion, avocado, olive oil, lime juice, and cilantro. Chill it and watch it vanish.🍷 The Truth About the Food ComaEveryone blames tryptophan, but the real reason for that post-Thanksgiving crash is carbs, alcohol, and portion size.When you load up on potatoes, rolls, and pie, your insulin spikes, helping tryptophan turn into melatonin — your sleep hormone. Add a glass (or three) of wine and you’re down for the count.To avoid it, eat slowly, take a short walk after dinner, and save dessert for later. Your pancreas will thank you.🍰 Dessert and a ConfessionI’m a surgeon, not a baker. So, I buy my pumpkin pie from Costco and serve it with vanilla ice cream. Sometimes, simplicity really is the secret ingredient.🔥 FORK U with Flavor — Coming Soon LiveWe’re launching a new live cooking show called FORK U with Flavor!Join me on TikTok (@drterrysimpson) and maybe Instagram (@drterrysimpsonmd) as we cook together, talk food science, and share a few laughs.Paid Substack subscribers at drsimpson.com get ingredient lists and recipes ahead of time so you can cook along live. Everyone else gets the replay links and recipes afterward.If you can’t watch me set off the occasional smoke alarm, you haven’t lived.❤️ A Final ThoughtWherever you live — America, Canada, or across the pond — Thanksgiving reminds us that food connects us all.Eat well. Be grateful. And remember, food isn’t just medicine — it’s connection, culture, and joy.Happy Thanksgiving from me, Dr. Terry Simpson, and the FORK U team.

When Vitamin D Isn’t Sunshine in a BottleVitamin D is sold as bottled sunshine. Social media says it boosts immunity, prevents cancer, and makes you live longer. But science says something very different — and megadoses pushed by influencers like Dr. Eric Berg can do more harm than good. Here’s what you need to know.☀️ The Sunshine Vitamin — and the Myth That FollowsVitamin D has been called the sunshine vitamin for over a century.We discovered it when children in industrial cities developed rickets — bones so soft they bent like rubber.The cure wasn’t pills. It was sunlight and milk fortified with Vitamin D.Today, that history is lost under a pile of influencer ads.Scroll through TikTok or YouTube, and you’ll see people claim Vitamin D cures everything — from fatigue to depression to cancer.One of the loudest voices is Dr. Eric Berg, who calls himself a “doctor.”Here’s the problem: he’s not a physician. He’s a chiropractor.And in California, chiropractors aren’t allowed to call themselves physicians. For good reason.Dr. Berg recommends doses of Vitamin D that are ten to twenty times higher than medical guidelines. That’s dangerous advice.Let’s look at what real science — not social media — tells us.🧬 What Vitamin D Actually DoesVitamin D isn’t really a vitamin. It’s a hormone that helps your body absorb calcium, strengthen bones, and regulate parts of your immune system.Most adults need 600 to 800 IU per day — not 10,000.If your level is low, your doctor may recommend a short course of higher doses, but chronic mega-dosing can lead to toxicity.So how much Vitamin D do you actually need?That depends on your sun exposure, skin color, diet, and where you live. People who live in northern climates or rarely go outside might need a supplement — but the rest of us get plenty from sunlight and food.📊 What the Research ShowsThe VITAL Trial, published in The New England Journal of Medicine (2019), followed over 25,000 people taking Vitamin D or a placebo.The result? No meaningful reduction in cancer, heart disease, or death.Other major studies say the same thing.If your Vitamin D levels are normal, taking more doesn’t improve health — it just makes your urine more expensive.There are benefits for people who are deficient, but that’s not most of us.A simple blood test can tell you if you truly need supplementation.⚠️ Too Much of a Good ThingVitamin D toxicity is not rare.Excess doses can cause calcium levels in your blood to spike, leading to nausea, confusion, kidney stones, and even heart rhythm problems.There is no benefit to megadoses of vitamin D (link)🍳 Real Food, Real SunshineHere’s the truth: you can get enough Vitamin D the way nature intended.Good sources include:Salmon, sardines, and tunaEggs and fortified milkMushroomsAnd, of course, sunlightTen to fifteen minutes of midday sun on your arms and legs a few times a week is usually enough.If you live in Alaska in January, sure — take a supplement.But for most of us, a walk outside beats a handful of pills.🧠 Why We Love PillsIt’s easy to see why Vitamin D is so popular.It promises health without effort.Pop a pill instead of taking a walk, eat poorly, but believe you’re fixing it — it’s the illusion of health without the habit of health.But biology isn’t fooled.Our bodies need balance, not shortcuts.Supplements can help fill a true gap — not when they replace good food and lifestyle.🩺 The TakeawayVitamin D is essential — just not magical.If you’re deficient, fix it.If you’re not, skip the megadoses and save your kidneys.And please — don’t take medical advice from a chiropractor on YouTube.The best way to get your Vitamin D?Eat well. Move more. Go outside.That’s the real sunshine therapy.🧾 ReferencesManson JE et al. Vitamin D Supplements and Prevention of Cancer and Cardiovascular Disease (VITAL Trial).

Animal Protein and Cancer Risk: What the Science Really SaysRecently, Mark Hyman posted on X (formerly Twitter) that a new study suggests eating more animal protein might actually lower your risk of cancer. The study he pointed to came from the NHANES dataset—a U.S. survey of diet and health. It sounded reassuring, but it doesn’t line up with the bulk of the evidence. Here is the story about Animal protein and cancer risk:Let’s dig into what the science really shows.Red and Processed Meats: Where the Risk Is ClearIf you want the strongest evidence, look at red and processed meats. Large prospective cohort studies and systematic reviews consistently show that higher intake of these foods increases cancer risk. The effect is clearest for colorectal cancer, but we also see it in breast, endometrial, and even lung cancer.[1–6]How big is the risk? Recent meta-analyses and systematic reviews find relative risks (RRs) and hazard ratios (HRs) in the 1.10–1.30 range for the highest vs. lowest intakes. For example, a comprehensive meta-analysis reported that every 50–70 grams per day of red or processed meat increased colorectal cancer risk by 15–32% (HR 1.15–1.32).[3,5] Processed meat generally carries more risk than unprocessed red meat.[2–3,6]That’s why the American Cancer Society recommends limiting red and processed meats. Their advice is clear: swap them out for fish, poultry, or legumes when possible.[15]Fish: A Safer BetThe data on fish tells a different story. Multiple studies and meta-analyses find a modest reduction in colorectal cancer risk with higher fish intake (SRR 0.94, 95% CI 0.89–0.99).[7–8] In fact, adding 50 grams of fish per day reduces risk by about 4%.Pescatarian diets (no red meat, but including fish) show even more protection. Compared to meat-eaters, pescatarians had a 9% lower overall and colorectal cancer risk (RR 0.91, 95% CI 0.86–0.96).[9]Poultry: Mostly NeutralChicken and turkey usually get lumped in with “animal protein.” But when you pull the data apart, poultry tells a different story. Most meta-analyses show a neutral or even slightly protective association with colorectal cancer (RR 0.79, 95% CI 0.63–0.99 for white meat).[10–12]That said, a few studies hint at possible links with certain blood cancers, but those findings aren’t strong or consistent.[5,10] For most people, poultry is a much safer choice than red or processed meats.Dairy: A Mixed PictureDairy is tricky. On one hand, milk and calcium-rich foods are consistently linked to a lower risk of colorectal cancer (RR 0.93, 95% CI 0.91–0.94).[4,13] On the other hand, high intake of milk or calcium may slightly increase the risk of prostate and endometrial cancers (RR 1.09–1.10).[13–14]No consistent associations are found for breast or ovarian cancer. Cheese intake in particular may even have protective effects, but results vary.Why the Confusion?So why did that NHANES study Mark Hyman highlighted find a small reduction in cancer mortality with higher animal protein? A few reasons:NHANES relies on a single dietary recall—one snapshot in time that may not reflect long-term habits.It doesn’t separate red and processed meat from healthier animal proteins like fish or poultry.Residual confounding (differences in lifestyle factors that aren’t fully accounted for) may skew the results.When you put NHANES side by side with larger, longer-term studies and meta-analyses, it looks like the outlier. The overwhelming weight of evidence shows that red and processed meats increase cancer risk, while fish, poultry, and some dairy products are safer or even protective in specific cases. Animal protein and cancer risk is positive.The Bottom LineProtein matters—but the source matters more.Red and processed meats: consistently linked to higher cancer riskFish: modestly protective, especially for colorectal cancerPoultry: generally neutral, sometimes protectiveDairy: lowers colorectal risk, but may raise prostate and endometrial cancer riskThe American Cancer Society sums it up well: limit red and processed meats, and lean into fish, poultry, beans, and plant-based proteins.[15]References[1] Rock CL, Thomson C, Gansler T, et al.

When Green Tea Isn’t ChemotherapyIntroductionFood is powerful. Eating well lowers your risk of many diseases, including cancer. Yet food is not chemotherapy. Still, the idea that broccoli or green tea could replace cancer treatment is tempting. It feels safe, natural, and hopeful.However, cancer is not treated with vegetables or tea. Cancer is treated with medicine. Let’s break down what food can and cannot do when it comes to cancer.Broccoli and Cruciferous VegetablesBroccoli, cabbage, Brussels sprouts, and other cruciferous vegetables contain natural compounds like sulforaphane. In lab studies, these compounds slow cancer cell growth. That is promising.Furthermore, population studies show that people who regularly eat cruciferous vegetables often have a lower risk of colon, lung, and breast cancers. So, broccoli can help lower risk.But here is the key point: broccoli does not cure cancer. No oncologist prescribes broccoli as chemotherapy. Prevention is not the same as treatment.Green Tea and Its LimitsGreen tea is another food often linked to cancer prevention. It contains catechins, such as EGCG, which in test tubes can slow cancer cell growth. Some studies even suggest that people who drink green tea regularly may have slightly lower cancer rates.But again, that is prevention. Once cancer begins, drinking green tea will not stop it. And when taken as concentrated supplements, green tea extracts can actually harm the liver.So, green tea is a fine beverage. But it is not chemotherapy. Personally, I prefer black tea — green tea tastes a little too much like pond water for me.Scams and False HopeSadly, the gap between prevention and treatment is where scams thrive. You’ve probably heard of things like:Gerson Therapy: organic juices and coffee enemas, still promoted in Mexico. No evidence, high risk.Apricot pits and soursop: marketed as natural cures, but linked to toxicity.Ivermectin: useful for parasites, but not proven in cancer.Then there’s the Warburg effect. Otto Warburg correctly observed that cancer cells use sugar differently. But modern science has shown cancer is not a “sugar disease.” It is a DNA disease caused by mutations. Cancer cells can grow on sugar, ketones, and even vitamins. You cannot starve cancer with diet.What Medicine Has DoneNow, let’s talk about the real success stories.Chemotherapy in the past was harsh, like carpet bombing. Yet it saved lives. My brother Jimmy was diagnosed with stage 4 Hodgkin’s disease in 1969. Thanks to experimental chemotherapy and radiation, he lived 37 more years.Today, treatment is even better. We have:Targeted therapies that hit the exact mutation in a tumor.Immunotherapy drugs that unleash the body’s own defenses.Combination therapies that extend survival with fewer side effects.And vaccines are changing everything. The HPV vaccine prevents cervical, anal, and many oral cancers. It may even help lower melanoma risk. Researchers are now studying vaccines for brain cancers like glioblastoma and even for pancreatic cancer.No apricot pit will ever do that.Food Still MattersWe should not ignore food. A poor diet filled with ultra-processed foods and low in fiber increases cancer risk. In fact, the rise in colon cancer among younger adults is likely tied to diets low in fiber and high in processed foods.The Mediterranean diet, rich in fruits, vegetables, whole grains, olive oil, and legumes, does more than prevent cancer. The large EPIC studies show it also lowers the risk of cancer coming back after treatment. That makes it the best diet for cancer prevention and recurrence.So yes, food matters. Food empowers you. But food is not medicine. Food lowers risk. Medicine treats disease. Together, they protect us.ConclusionGreen tea and broccoli are healthy. The Mediterranean diet is the best prevention strategy we know. But once cancer develops, treatment is essential.Food isn’t chemotherapy. Medicine is. And that is something we should all be grateful for.ReferencesWorld Cancer Research Fund/American Institute for Cancer Research. Diet, Nutrition, Physical Activity and Cancer: a Global Perspective.

Food Is Powerful, But It’s Not EnoughFood shapes our health. Eating beans, fruits, vegetables, and whole grains can lower the risk of diabetes and other chronic conditions. Yet food does not replace medicine. Clearly, diets high in ultra-processed foods make diabetes worse. And yes, eating better is the most empowering thing anyone can do.Still, some claim that modern food is the only reason we have chronic diseases like diabetes. They argue that if people only ate “real food,” there would be no need for medicine. History proves otherwise.The Story That Changed Everything: Dr. Banting and InsulinIn the early 1920s, Dr. Frederick Banting and Charles Best discovered insulin in Toronto. At the time, children with type 1 diabetes had no future. Families were told to put their kids on starvation diets, hoping to add a few months to their lives. Death was certain.Then came insulin. Doctors injected it into children already in comas. One by one, they woke up. They sat up, asked for food, and hugged their parents. What had been a hospital ward of silence turned into a place of joy.Insulin was the fastest-adopted drug in history. Banting became the youngest Nobel Prize winner at the time. That discovery did not come from food. It came from science and medicine.Two Types of DiabetesThere are two main types of diabetes.Type 1 diabetes happens when the pancreas loses all ability to make insulin. Without insulin, sugar cannot move into cells, and life cannot continue. That is why every person with type 1 diabetes needs insulin from the first day of diagnosis.Type 2 diabetes is different. In this case, the body still makes insulin, but the cells resist it. Over time, the pancreas wears out. That is why many people with type 2 eventually need insulin too. It is not failure. It is simply how the disease progresses.Food can help manage both types, but food alone is never enough.What Beans Can DoBeans are one of the best foods for blood sugar. They are full of soluble fiber, which slows down glucose absorption. They also provide plant protein and have a low glycemic index. That means they don’t spike blood sugar the way soda or white bread does.Research shows that eating beans regularly can lower hemoglobin A1c — the measure of long-term blood sugar — by about 0.3 to 0.5 percent. That is a real effect from food.Beans are also practical. They are inexpensive, found almost everywhere, and have been eaten by humans longer than almost any other protein source.Why Beans Aren’t MedicineNow let’s compare beans to metformin.Metformin is the first-line drug for type 2 diabetes. It lowers A1c by 1 to 2 percent. That’s two to four times more than beans. Metformin also lowers the risk of heart disease and has decades of safety data behind it.So while beans help, they are not metformin. If blood sugar is high, no amount of hummus or chili will bring it back to safe levels. Medicine is needed. Food lays the foundation, but medicine does the heavy lifting.The Best Diet for Diabetes: The Mediterranean PatternWhen it comes to diet, the evidence is clear. The Mediterranean diet is the best overall eating plan for diabetes.This diet includes:FruitsVegetablesOlive oilNutsLegumes (yes, beans!)Whole grainsNow, some people push back against whole grains. That may be because they grew up in the low-carb era, when grains were unfairly blamed for every health problem. But whole grains are healthy, especially for people with diabetes. They are far better for the body than bacon or butter.The Mediterranean diet does more than control blood sugar. It lowers cholesterol, reduces blood pressure, decreases inflammation, and protects the heart. And unlike fad diets, it is sustainable.Practical Ways to Add BeansAdding beans to meals is easy. Here are a few examples:Swap ground beef for black beans in chiliAdd lentils to soups or stewsRoast chickpeas for a crunchy snackUse hummus instead of cheese spreadToss peas into pasta, rice, or grain bowlsThese small swaps improve blood sugar, lower cholesterol, and keep you full. Combined with the Mediterranean diet, the benefits are even stronger.Don’t Fall for ScamsUnfortunately, scams are everywhere. Keto and carnivore diets claim to cure diabetes. While they may lower blood sugar in the short term, they raise saturated fat intake. That increases the risk of heart disease, which is the biggest threat to people with diabetes.And cinnamon? It makes oatmeal taste great, but cinnamon pills do not cure diabetes. The science simply doesn’t support it.The TakeawayFood matters. Food lowers risk. Food empowers people to take control. But food is not medicine.Food is food. Medicine is medicine. Together, they save lives.ReferencesBanting F, Best C. Discovery of insulin, 1921–1922.American Diabetes Association.

When Salmon Isn’t a StentHeart disease was four times more deadly than it is today. In those days, we had no statins, no stents, and no bypass surgery. Food was the only weapon doctors had.Pharmacies in Rome and Greece even stocked extra virgin olive oil for patients with “hardening of the arteries.” Doctors sent people to pick up bottles, almost like prescriptions. Olive oil wasn’t curing clogged arteries, but it showed an early recognition that diet mattered.Then scientists noticed something bigger. In certain Mediterranean villages, people lived longer with far less heart disease. It wasn’t genetic. Relatives who moved to cities and switched to Western diets developed heart disease much earlier.Researchers didn’t stop there. They followed men in villages across Europe and the Mediterranean for decades. Some communities ate diets heavy in saturated fats. They developed clogged arteries and heart disease quickly. Other communities ate diets rich in fruits, vegetables, legumes, fish, nuts, and olive oil. They had much lower rates of heart disease. This pattern became the foundation of what we now call the Mediterranean Diet.At that time, diet gave us hope. But today, we know that food alone is not enough.Lyon Heart StudyThe Lyon Diet Heart Study proved how powerful diet could be. Conducted just as statins came onto the market, it showed that patients with heart attacks who switched to a Mediterranean-style diet had a 70% lower risk of another cardiac event. That meant fewer heart attacks and fewer deaths.Later, the PREDIMED trial confirmed these results. In high-risk adults, the Mediterranean Diet reduced major cardiovascular events by about 30%. That’s impressive, but it also raises a question: can people sustain it? Adherence usually means sticking with the diet about 70 percent of the time. That’s not perfect.Here’s a personal example. I have hypercholesterolemia and a strong family history of heart disease. I follow the Mediterranean Diet carefully. But even with strong adherence, my LDL cholesterol never dropped below 180. With two drugs — Zetia and Crestor — my LDL is now in the 40s. Food helps. Medicine saves.Atherosclerosis begins early in lifeThe PESA Heart Study showed why this matters. Researchers in Spain followed adults who felt perfectly healthy. Using advanced imaging, they found more than 60 percent already had plaque in their arteries. Atherosclerosis begins silently, and often decades before symptoms appear.The JUPITER trial with rosuvastatin (Crestor) proved what medicine can do. Statins reduced cardiovascular events by 44 percent, and the study had to stop early because the benefit was so strong.And then there’s Dean Ornish. His program is often called the “diet that reverses heart disease.” But it was never just a diet. His patients quit smoking, took statins, took blood pressure medications, and practiced yoga. Ornish proved that lifestyle matters — but it was food and medicine together that made the difference.Barbara O'Neill and Cayenne PepperMeanwhile, scammers still sell false hope. Barbara O’Neill, banned from giving health advice in Australia, charges thousands for seminars where she claims cayenne pepper “opens arteries.” That’s pure fiction. Cayenne is a spice, not a stent. She also claims cholesterol guidelines only exist to enrich drug companies. Yet my three-month supply of Crestor costs $2.36, while she profits thousands. The real con is clear.So here’s the truth: salmon is healthy, but it isn’t a stent. Olive oil helps, but it isn’t a statin. Food prevents disease. Medicine treats it. Together, food and medicine are unbeatable.Referencesde Lorgeril M, et al.

When Bananas Aren’t a Beta BlockerPeople love to believe that food can replace medicine. We talked about this in Episode One, where I explained that Hippocrates never said “let food be thy medicine.” Still, the myth endures.Food does matter. The right eating pattern can lower blood pressure. One of the best-studied is the DASH Diet—short for Dietary Approaches to Stop Hypertension. It is often called America’s version of the Mediterranean Diet. While the Mediterranean Diet was being mapped out for overall health, the DASH researchers asked a sharper question: what foods can lower blood pressure directly?Why DASH Is UniqueUnlike most nutrition studies, the original DASH trial provided all the food to participants. That meant researchers knew exactly what people ate, meal after meal. This is rare and expensive, but it gave them confidence in the results.The DASH diet emphasizes:Fruits and vegetables, especially potassium-rich foods like bananas, beans, and leafy greensWhole grainsLean proteins, like fish and poultryLow-fat dairyLess red meat, sweets, and sodiumBecause it combined several food groups, DASH worked quickly. Within two weeks, blood pressure dropped.What the Studies ShowThe results were consistent. People following DASH lowered their systolic blood pressure (the top number) by 8–11 mmHg and their diastolic pressure by 5–6 mmHg. That is about the same as one standard blood pressure pill.Even more important, DASH showed that sodium reduction matters. Those who cut sodium intake to 1,500–2,300 milligrams per day saw the greatest improvements. This shattered the myth that unlimited salt is safe. Too much sodium raises blood pressure, increases heart disease risk, and fuels strokes.The Role of ElectrolytesThis is where things get messy. Electrolytes, especially sodium, are necessary during prolonged exercise—typically more than 1–2 hours, in hot weather, or when sweating heavily. Under those conditions, sodium helps prevent hyponatremia, a dangerous drop in blood sodium levels.However, for most people exercising less than an hour, water is enough. Regular meals will replace lost sodium. Salty drinks or powders aren’t required. In fact, most commercial sports drinks don’t even contain enough sodium to match sweat losses in extreme events.The Salt Supplement ScamHere is where the grift appears. Shirtless salesmen on social media love to sell high-priced mango-flavored salt packets as “essential” electrolytes. They promise performance and recovery, but they may actually raise your blood pressure and put you at risk.Science says otherwise. Electrolyte supplementation should be individualized and used with caution. People at highest risk from unnecessary sodium loading include:Those with hypertension, heart failure, or kidney diseaseWomen, who are more prone to overhydration and hyponatremia due to smaller body size and lower sweat ratesOlder athletes or those with low body massRecreational athletes who follow outdated advice to “drink as much as possible”Even ultra-endurance athletes cannot rely on sodium supplements alone. If they drink more than they lose, sodium will not prevent hyponatremia and may make things worse. The best strategy is to drink to thirst and use salty foods or fluids only when truly needed.What a DASH Day Looks LikeHow can you follow DASH in real life? Here’s one sample day:Breakfast: Oatmeal with berries and a bananaSnack: A handful of unsalted nutsLunch: Black bean and vegetable salad with vinaigretteDinner: Grilled salmon with leafy greens and brown riceExtra: Low-fat yogurt or skim milkThis pattern supplies potassium, magnesium, calcium, and fiber—nutrients that relax blood vessels and lower pressure naturally. Notice what’s missing: salty snacks, processed food, and canned soups.Food and Medicine TogetherSo what does it all mean? The DASH Diet lowers blood pressure and improves overall health. But it does not replace medication. Blood pressure medicines—ACE inhibitors, ARBs, calcium channel blockers, diuretics—reduce systolic pressure by 20–40 mmHg. That is two or three times more than DASH.Food helps. Medicine saves. Together, they work best.The Bottom LineBananas, beans, and leafy greens are wonderful. Electrolyte supplements are rarely needed. Expensive salt powders sold by social media influencers are scams. And the DASH Diet? It’s real, it works, and it shows that food has power—just not enough to replace your beta blocker.

When Tofu Isn’t a StatinPeople love to say “food is medicine.” Some even claim Hippocrates himself said it. But here’s the thing: he didn’t. The phrase does not appear in any of his surviving writings. In fact, historians believe the line was created centuries later and then falsely attached to Hippocrates to give it weight.Still, the idea persists. Even the current head of HHS, Robert F. Kennedy Jr., has repeated the myth. And when RFK Jr. is your fact-checker, you know you’re in trouble.Now, as someone certified in Culinary Medicine, I believe food is incredibly powerful. Eating the right foods can prevent disease, improve health, and help you live longer. However, food alone rarely works as well as actual medicine. That is especially true when it comes to cholesterol.The Portfolio DietIn the early 2000s, Dr. David Jenkins and his team introduced what they called the Portfolio Diet. Instead of focusing on one “superfood,” the diet combines several cholesterol-lowering foods:Soy proteinNuts, like almondsViscous fibers from oats, barley, or psylliumPlant sterols from fortified foodsEach one has a small effect. But when you put them together, the benefits add up.Why does it work? Cholesterol gets secreted by your liver into bile, then travels into your gut. Normally, most of that cholesterol is reabsorbed into your bloodstream. But fiber and plant sterols bind to cholesterol and drag it out of your body. That’s why bowel movements are brown—bile is brown, and fiber helps carry it out. More fiber means you feed your gut bacteria and flush away cholesterol. It really is a win-win.What the Studies ShowThe Portfolio Diet has been tested in multiple clinical trials. In one JAMA study, people who followed the diet lowered their LDL cholesterol by about 13 to 14 percent over six months. That translated to a drop of about 24–26 mg/dL.Other studies show that people who stick with it can lower their LDL by 17 percent on average. Some who were especially diligent saw drops of more than 20 percent at one year. The Portfolio Diet also improves non-HDL cholesterol, apolipoprotein B, and long-term risk for heart disease.So yes—it works. In fact, the effect is similar to what you get from early statins like lovastatin.What It Looks Like in Real LifeThe science sounds great. But how do you actually eat this way? Here’s one example day:Breakfast: Oatmeal made with soy milkSnack: A handful of almonds (about 25–30 grams)Lunch: Lentil soup with whole-grain breadDinner: Tofu stir-fry with vegetables and barleyExtra: Two grams of plant sterols, often from fortified margarine spreadsThat daily pattern gives you soy protein, fiber, nuts, and plant sterols. But here’s the challenge: it takes careful planning to hit the right doses every day. It’s not impossible—but it is hard to sustain.How It Differs from the Mediterranean DietMany people confuse the Portfolio Diet with the Mediterranean Diet. Both are plant-forward, emphasize nuts, legumes, whole grains, and lower cardiovascular risk. However, the Mediterranean Diet is broader and easier to follow. It includes olive oil, fish, fruits, vegetables, and even moderate wine.The Portfolio Diet, on the other hand, is very prescriptive. You must hit specific amounts of soy protein, fiber, and sterols daily. Think of the Mediterranean Diet as the entire restaurant, while the Portfolio Diet is just one corner of the menu—focused squarely on cholesterol.What About Statins?Statins are still the gold standard. Modern statins like atorvastatin or rosuvastatin lower LDL cholesterol by 30 to 50 percent, far more than diet alone. More importantly, they reduce heart attacks and strokes by 25 to 40 percent.And there’s more. When you combine a statin with Zetia (ezetimibe), which blocks cholesterol absorption in the gut, you can see another 20 percent reduction in LDL. That’s essentially the pharmaceutical version of the Portfolio Diet. Together, statins plus Zetia can lower LDL cholesterol by 65 to 70 percent.The Bottom LineThe Portfolio Diet lowers cholesterol. The Mediterranean Diet improves heart health. Both are excellent for prevention and long-term wellness. But when your cholesterol is high or your risk is significant, medicine is usually necessary.The best approach is not “food or medicine.” It’s food and medicine. Eat Mediterranean, fold in Portfolio Diet elements, and—if your doctor recommends it—add a statin or Zetia.Because food lays the foundation. Medicine builds the house. And together, they keep the roof from caving in.REFS1.
