Myth #2
If you eat more protein, you'll build more muscle.
To a point, sure. But put down the shake for a sec. Protein promotes the muscle-building process, called protein synthesis, "but you don't need exorbitant amounts to do this," says John Ivy, Ph.D., coauthor of Nutrient Timing. If you're working out hard, consuming more than 0.9 to 1.25 grams of protein per pound of body weight is a waste. Excess protein breaks down into amino acids and nitrogen, which are either excreted or converted into carbohydrates and stored.
