Story summary

An analysis finds individual reactions to food vary, with hunger, appetite, and fullness governed by different brain regions and dopamine guiding reward.
Stress disrupts these regulatory systems, increasing the drive to eat but reducing self-control.
Frequent refined carb and fat consumption dulls appetite signals, making it harder to stop.
Experts propose "food-mind fluency" to understand impulses, but personal responsibility must be paired with policy action addressing the food environment.
