Quizplus · Accepted Answer

Feeling full is primarily due to the release of Cholecystokinin (CCK), while overall food intake and energy balance are regulated by Leptin. CCK is released in response to food intake to help reduce appetite, whereas leptin is produced by fat cells and helps to regulate energy balance by inhibiting hunger.
