Leptin

Leptin is a hormone produced by fat cells in the body that plays a role in regulating appetite and body weight. It is released into the bloodstream when food is consumed and travels to the brain where it signals fullness and satisfaction. Leptin levels increase when the body has plenty of stored fat and decrease when the body has depleted its fat stores. By regulating appetite and body fat, leptin plays an important role in maintaining healthy weight. It also helps to regulate metabolism and immune system function. Low leptin levels can lead to weight gain, increased food cravings, fatigue, and abnormal immune system function. Abnormal levels of leptin can result from genetic mutations, lifestyle factors such as diet, exercise, and stress management, and certain medical conditions. Improper management of leptin levels can lead to a wide range of health complications.
