Hormonal control of appetite and body fat. Leptin and ghrelin seem to be the big players in regulating appetite, which consequently influences body weight/fat. When we get hungrier, we tend to eat more. When we eat more, obviously, we maintain our body weight or gain that weight back. Both leptin and ghrelin are peripheral signals with central effects. In other words, theyâre secreted in other parts of the body (peripheral) but affect our brain (central). Leptin is secreted primarily in fat cells, as well as the stomach, heart, placenta, and skeletal muscle. Leptin decreases hunger. Ghrelin is secreted primarily in the lining of the stomach. Ghrelin increases hunger. Both hormones respond to how well-fed you are; leptin usually also correlates to fat mass â the more fat you have, the more leptin you produce.
Although regulation of fat stores is deemed to be the primary function of leptin, it also plays a role in other physiological processes, as evidenced by its multiple sites of synthesis other than fat cells, and the multiple cell types beside hypothalamic cells that have leptin receptors.n 1950, a non-obese mouse colony being studied at the Jackson Laboratory produced a strain of obese offspring, suggesting that a mutation had occurred in a hormone regulating hunger and energy expenditure. Mice homozygous for the so-called ob mutation (ob/ob) ate voraciously and were massively obese.
