Question

Quizplus · Accepted Answer

Leptin is a hormone produced by fat cells that signals to the brain to decrease hunger and increase energy expenditure. It does not increase hunger (as stated in option B) and does not lead to obesity (as stated in option C). Additionally, it does not come from the stomach (as stated in option A). Research has shown that leptin can decrease the reinforcing value of food, meaning that it reduces the pleasure and desire associated with eating, which may contribute to decreased food intake and weight loss.
