So many trainers out there have gotten it into their heads that protein is the ONLY macronutrient responsible for adding muscle mass. They tell you to avoid carbohydrates because they will only make you fat and not help you put on lean muscle mass. These trainers are sadly misinformed. Carbohydrates are the body’s preferred source of energy. Carbs are stored as glycogen in the liver and in muscle cells. When energy is needed, the body converts carbs into ATP (energy your body uses) by glycolisis.
If there are not enough carbs, your body will convert protein into an energy source. This process is called gluconeogensis. Needless to say, taking protein away from muscle cells to make energy is not going to help you pack on lean muscle mass. So for all of you who have heard trainers say, eat protein, limit carbs…realize what is really going on inside your body. Your massive protein intake is forced to energize your body because carbohydrate levels are depleted, thereby limiting the gains from all your hard work in the gym.
