Two main brain systems control feeding behavior. The homeostatic system ensures the body gets the right amount of energy to maintain balance, while the hedonic system drives eating based on pleasure. These systems are closely connected and sometimes conflict, as pleasurable foods can override feelings of fullness, leading to overeating.
