Explanation:

Leptin is a hormone produced by fat cells. It acts on the hypothalamus in the brain to regulate appetite and body weight. When fat stores increase, leptin levels rise, signaling the brain to reduce food intake and increase energy expenditure. Conversely, when fat stores decrease, leptin levels fall, signaling the brain to increase food intake and reduce energy expenditure. This helps maintain a stable body weight.

Answer:

Regulate appetite and body weight
