Question

Quizplus · Accepted Answer

Leptin is a hormone that is produced by adipose cells (fat cells) and the amount of leptin that is secreted into the bloodstream is directly related to the amount of body fat a person has. Leptin acts on the hypothalamus in the brain to regulate appetite and energy expenditure. When a person has more body fat, they produce more leptin, which helps to suppress appetite and increase metabolism. Conversely, when a person has less body fat, they produce less leptin, which can increase appetite and decrease metabolism.
