Why Calorie Counting Fails — and What Hunger Really Controls

Why calorie counting fails — and why hunger, not willpower, drives eating behavior.

Episode #244

🎙️ If calories alone controlled weight, calorie counting would work. But it doesn't — because hunger is the real driver.

In this episode, Dr. Terri Lance is joined by Dr. Jason Fung to unpack why the traditional "eat less, move more" model fails so many people. They explain why calorie counting ignores the biology of hunger and how hormones, food quality, and different types of hunger determine whether calories are burned or stored. This conversation reframes weight gain as a biological process — not a personal failure — and lays the groundwork for understanding eating behavior through hunger regulation rather than willpower.

👉 What you'll learn: • Why calorie counting fails for long-term weight loss • How hunger — not willpower — drives eating behavior • Why hormones determine whether calories are burned or stored • The difference between homeostatic, hedonic, and conditioned hunger • How ultra-processed foods disrupt satiety and increase hunger • Why focusing on hunger leads to more sustainable results than restricting calories
