Why is obesity so difficult to reverse even when people try to eat less? In this episode, Ethan sits down with Dr. Jason Fung, nephrologist and author of The Obesity Code and The Diabetes Code, to unpack the hormonal science behind weight gain, insulin resistance, and type 2 diabetes. They explore why the calorie model of weight loss often fails, how insulin drives fat storage, and why fasting can be a powerful metabolic tool. The conversation also touches on addiction, modern food environments, and sustainable approaches to health.
