Leptin The Hunger Hormone That Regulates Appetite
What Is Leptin?Leptin, from the Greek word leptos which means thin, is produced in adipose tissue, or the stored fat of your body. Leptin acts in the hypothalamus, the part of your brain that is responsible for coordinating many body functions, including your appetite to help control food intake and weight loss. Following a meal leptin is released from your fat and enters your blood. It travels to your brain to deliver a message that you are full. Leptin also sends the message about how much fuel you have taken on board. An increase in leptin warning signals leads to decreased food intake, increased energy expenditure and fat burning which promotes weight loss. Leptin and Weight LossLeptin research shows that the level of leptin circulating in the bloodstream is directly proportional to the total amount of body fat, or adipose tissue. Women, who tend to have a higher percentage of body fat than men produce more leptin. Obesity is associated with greatly elevated leptin concentrations. What is Leptin Resistance?Obese people develop resistance to the action of leptin. Therefore leptin is unable to produce its normal effects on controlling the appetite and stimulating weight loss. A healthy diet, regular exercise, restorative sleep and specific nutrients help optimise the function of leptin in your body.
