Why You Can't Stop Eating Ultra-Processed Foods

Dr. Chris van Tulleken explains the UPF crisis: 50-60% of calories in the UK and US now come from ultra-processed food. His self-experiment showed measurable brain changes from 4 weeks of UPF-heavy eating. Why the food industry designs food to override satiety.

Canon

Van Tulleken: 4 weeks of eating 80% UPF produced measurable changes in brain connectivity — the same patterns seen in substance addiction. The reward centers became more strongly connected to regions controlling habitual (automatic) behavior.

Highlights

The food industry engineers overconsumption — UPF is designed to override your body's stop signals
Van Tulleken: ultra-processed food is industrially formulated to maximize consumption. Soft textures reduce chewing time (less satiety signaling), flavor engineering prevents sensory-specific satiety, and the combination of refined carbs and fat hits the 'bliss point.'
