WHAT IS LEPTIN?
Leptin is a hormone produced by the fat cells in your body. The word leptin comes from the Greek word Leptos (meaning thin). The amount of leptin released from those fat cells is dependent upon how much fat there actually is. Basically, Iif you have more fat you have more leptin. Leptin essentially controls your metabolism, hunger, and energy expenditure. A leptin system that is working properly improves brain fitness, mental sharpness, leads to better memory, and enhances mood.
