Understanding Leptin and Its Functions

What is the primary function of leptin in the body?

• To break down proteins

• To store vitamins

How does leptin influence body weight regulation?

• By increasing fat storage

• By signaling the brain to reduce food intake

• By converting carbohydrates into fats

• By increasing muscle mass
