Leptin

Leptin is your body’s “fullness signal” — made by fat cells to tell your brain you have enough energy stored. When leptin is working, it curbs hunger and boosts metabolism. But if levels stay elevated, your brain can become leptin-resistant — you feel hungrier, metabolism slows, and it’s harder to lose weight. Think of leptin as your long-term energy thermostat — key for fat loss, energy regulation, and hormonal balance.
