In this episode of the Keto Made Simple podcast, Dr. Eric Westman sits down with Dr. Jason Fung to break down one of the biggest misconceptions in modern health: weight loss is NOT just about calories. 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.
