Leptin is a hormone produced by fat (adipose) tissue that suppresses hunger. It sends signals to the hypothalamus in the brain to decrease appetite and increase energy expenditure. Higher levels of leptin indicate a surplus of fat stores and a lower level of appetite, while lower levels of leptin indicate a deficit of fat stores and a higher level of appetite.
