Together, they achieve more than either does on its own. Carbs may help protein reach your muscles faster, speeding growth. Meanwhile, some research suggests protein accelerates the buildup of glycogen. Even if you're on a low-carb diet, you should take in some carbs with your postworkout protein. Use a protein supplement that contains carbs, or add your own with whole fruit. Mix some in a blender with water and ice for the perfect postworkout treat. You can also use skim milk instead of a protein supplement—24 ounces (3 cups) provides 25 grams of protein, 35 grams of carbs, and a generous dose of muscle-building leucine.
