E16: Get Lean, Get Muscular, and Smash Aging and Chronic Disease with P.D. Mangan

“A decrease in insulin sensitivity and an increase in insulin resistance is often seen in aging and is the main feature of type 2 diabetes, but it doesn’t have to be this way. An attention to diet and exercise can maintain youthful levels of insulin sensitivity.” Those are the words of Dr. Mowll’s guest today — scientist, author, and blogger, P.D. Mangan.   With his scientific background, P.D. writes about health, fitness, and anti-aging through lifting weights, maintaining a paleo diet, and intermittent fasting. He’s written six books on health and fitness, including Muscle Up and Dumping Iron.   In their interview today, Dennis discusses how he uses his background in clinical biochemistry to understand diabetes and how to regulate blood sugar; why he gave up being vegetarian in favor of a low-carb, high fat diet; and how he cured his chronic fatigue. He also talks about why meat and saturated fats have very little — if anything — to do with our current health problems, the big problem with seed oil (most typically called vegetable oil) and what they do to our health, how high iron levels can be dangerous to our health, the importance of calorie restriction, how to slow the aging process, and prevent and reverse chronic disease. He also shares his journey of switching from being a marathon runner to giving up running in favor of resistance and strength training, as well as “vegetarian dark secrets,” and how the main contributors of the diabetes and obesity epidemic are actually plant foods.   Tune in to this week’s episode to hear about this scientist’s secrets to a long, healthy life!   Key Takeaways: [:58] All about Dr. Mowll’s guest today, P.D.
