If you still think weight loss is just “calories in, calories out,” this episode will challenge that assumption.
In this conversation with Dr. Jason Fung, author of The Obesity Code and The Hunger Code, we break down why obesity and persistent appetite issues are far more hormonal and metabolic than most people realize—and why ultra-processed foods may be resetting your body’s internal “fat thermostat.”
Here’s what we cover:
🍽️ The three types of hunger: homeostatic, hedonic, and conditioned
🧠 How hormones like leptin regulate a “body fat set point”
🥦 Why bulky, fiber-rich foods help regulate appetite
🥤 How blending and ultra-processed foods alter glucose and insulin responses
🍪 How modern food engineering amplifies cravings and overrides natural satiety signals
⚖️ Why reducing calorie intake alone often backfires as the body adapts by lowering metabolic rate
🧬 How insulin, the microbiome, and digestion influence fat storage and appetite
We also discuss fasting strategies, GLP-1 medications, digestion speed, and practical ways to reduce appetite without feeling deprived.
