If you'd like to lose fat and gain muscle, the best question to ask yourself is, Got milk?

Researchers at McMaster University found that men who sported that little white milk mustache post-workout lost more fat and gained more muscle than those who drank soy drinks or sports drinks with the same amount of protein and energy. With nine essential nutrients, milk seems to be the ideal post-workout drink.

What's even sweeter? Chocolate milk. Because cocoa beans have antioxidants, the childhood favorite makes for an even better snack after a hard session in the gym or at the studio.
