Dr. Fung's latest book, The Hunger Code: Resetting Your Body's Fat Thermostat in the Age of Ultra-Processed Food, challenges the calorie-centric model of obesity and offers a deeper, more honest look at why we eat the way we do — and what it actually takes to change.
In this episode, you'll hear:
- Why the calories in/calories out model fails — and what the hormonal model of obesity actually means
- The three types of hunger driving overeating: homeostatic, hedonic, and conditioned hunger — and why the social and emotional components may account for 90% of our eating behavior
- How ultra-processed foods are engineered to hijack the brain's reward system — and why that matters for food addicts
- The difference between fasting and starvation — and why the mindset behind fasting changes everything
- The dangers of using fasting as a punishment after a binge — and how to use it safely and intentionally instead
- Why a low-carb, higher-fat diet makes fasting more sustainable for people coming out of binge cycles
- Dr. Fung's honest take on GLP-1 medications like Ozempic — the benefits, the limitations, and why they're not the whole answer
- What Japan and Italy get right about eating culture that the U.S. has lost
- Why public policy — not just personal willpower — must be part of the solution to ultra-processed food addiction
