For decades, we’ve been told that “calories in vs calories out” is the key to losing weight — but what if that idea is completely wrong?Dr. Fung explains why hormones like insulin play a far more important role in fat storage, hunger, and metabolism than simple calorie counting. They discuss why so many diets fail, why people regain weight, and how your body actually regulates fat through a biological “set point” rather than willpower alone.The conversation dives deep into intermittent fasting, how it works, and why it can be such a powerful tool for weight loss and reversing metabolic disease. They also unpack the real reasons behind hunger — including emotional eating, food addiction, and the impact of ultra-processed foods that are engineered to keep you eating.Dr. Fung also shares insights on GLP-1 weight loss drugs, explaining why they work, where they fall short, and why relying on them without changing behavior can lead to long-term failure.If you’ve ever struggled to lose weight, felt like diets don’t work, or wondered why you keep regaining weight, this conversation will completely change how you understand fat loss, hunger, and metabolism.#keto #weightloss #fasting #lowcarb #nutrition #health #diet #fatloss #insulin #metabolism 00:00 Introduction00:30 Why calories don’t explain weight loss02:00 The failure of “calories in vs calories out”04:00 The real cause of obesity and diabetes07:00 Hormones and the body fat “set point”10:00 Why metabolism adapts against you13:00 Extreme weight loss cases explained15:00 Fasting and how it really works20:00 How long you can fast safely24:00 Blood sugar changes during fasting28:00 Insulin vs glucose explained32:00 Misdiagnosis in diabetes cases36:00 The Hunger Code explained40:00 Emotional eating and food addiction44:00 Ultra-processed foods and cravings47:00 Why social habits drive eating50:00 New dietary guidelines reaction52:00 GLP-1 drugs: benefits and risks55:00 Final thoughts on diet vs medication🟣 If you enjoy my channel and would like to support what I do there are a few different ways you can show your support listed below: 🟣BECOME A CHANNEL MEMBER ON YOUTUBEReceive priority comments, early access to new videos and join livestreams twice a month to ask me anything live!🟣Support the channel via PayPal if you don't want anyone taking a chunk of what you send me and you can set up a recurring payment https://www.paypal.com/donate/?hosted_button_id=ZDZK4SN7DJYXC🟣Vist Adapt Your Life Academyhttps://adaptyourlifeacademy.com/🟣Bestselling Book – END YOUR CARB CONFUSION:https://www.amazon.com/Your-Carb-Confusion-Eric-Westman🟣END YOUR CARB CONFUSION COOKBOOK:https://www.amazon.com/End-Your-Carb-Confusion🟣Free Guide: Dr. Westman's Carnivore Guide: https://adaptyourlifeacademy.com/carnivore-diet-explained-bonus/ ========================================================================🟣MY SOCIAL MEDIA 🟣Like my Facebook Page ➡️  https://www.facebook.com/AdaptYourLifeAcademy🟣Follow me on Instagram ➡️  https://www.instagram.com/adaptyourlifeacademy/🟣Follow me on X ➡️  https://x.com/drericwestman========================================================================🟣Dr. Eric Westman, Associate Professor of Medicine at Duke.
