Medical Definition of Leptin. Leptin: A hormone produced mainly by adipocytes (fat cells) that is involved in the regulation of body fat. Leptin interacts with areas of the brain that control hunger and behavior and signals that the body has had enough to eat.
Leptin is secreted from adipose tissue and travels through the blood to the brain and other organs. Leptin acts to decrease energy intake and increase energy expenditure. According to the Annual Review of Physiology, in the brain, leptin binds to leptin receptors, producing signals that lead to a decreased appetite.
