Purpose: Leptin is a hormone that regulates energy balance and body weight, acting as a critical communication link between fat cells and the brain. Key Roles in the Body • Signals the brain about energy reserves • Regulates appetite and hunger • Controls metabolism • Helps maintain long-term energy balance

• Males: 0.5 – 12.5 ng/mL

Interpretation of Results High Leptin Levels Indicate: • Excess body fat • Potential obesity • Possible leptin resistance • Higher risk of metabolic disorders
