Fact or fiction: More protein means bigger muscles

Seeing big, beefy bodybuilders chugging down protein shakes makes it seem like the more protein you eat, the bigger your muscles will get.

But if it was that simple, we could all look like Charles Atlas! Australian dietitian Sharon Natoli elaborates:

"To gain muscle mass you must have enough protein and carbohydrates in your diet to provide your body with the energy it needs to build muscle. But the only way to 'bulk up' is to use the muscles through strength training and exercise."

The bottom line: Myth

Exercise builds muscle, and no amount of protein bars will do it for you if you don't move your muscles.
