How Fructose Causes Metabolic Disease: SIMPLIFIED | Rick Johnson & Peter Attia

In Peter Attia's podcast The Drive Episode 194, he interviews Rick Johnson and they spend over two hours explaining how fructose causes metabolic disease: obesity, type 2 diabetes, etc. But it needs to be simplified and explained, and that's what I do in this video!

Dr. Johnson’s hypothesis is that fructose is prime cause of metabolic syndrome and the rapid uptick of modern diseases. He writes about it in his new book "Nature Wants Us to Be Fat". It explains a lot:

Why it's harder to stay lean when we get older.
Why athletes seem like they can eat anything they want.
Why most traditional calorie restrictions diets are so hard to maintain
Why keto, low-carb, and paleo diets have had so much success

And importantly, his theory of fructose metabolism is still totally consistent with thermodynamics, and the equation "Calories in minus calories out equals weight gained" is still true.
