Hedonic Hunger, Ultra-Processed Foods, and Why "Eat Less" Fails

Why do we keep eating when we're not physically hungry?

Episode #248 🎙️ Dr. Jason Fung and Dr. Terri Lance explore hedonic hunger—the drive to eat for pleasure rather than physical need.

In this episode, Terri and Dr. Fung examine how ultra-processed foods are engineered to maximize reward, how dopamine and food addiction shape eating behavior, and why the advice to simply "eat less" misses the real problem. They also explore conditioned hunger and how environment, advertising, and daily habits can drive eating even when the body does not physically need food.

This conversation challenges simplistic calorie-focused advice and reframes overeating through a biological and behavioral lens.

👉 What you'll learn: • What hedonic hunger is and how it differs from physical hunger • How ultra-processed foods are engineered to maximize pleasure and minimize satiety • Why some foods can trigger addictive eating patterns • How food addiction parallels other addictions in the brain • Why "eat less" fails to address the real issue • How conditioned hunger and environment influence eating behavior
