Question

Quizplus · Accepted Answer

Current research suggests that when leptin levels are high, the appetite and feelings of hunger decrease. Leptin acts on the brain to signal when the body has had enough food and to regulate energy balance. High levels of leptin indicate that there is enough fat stored in the body, thus reducing hunger and promoting energy expenditure.
