TRUE. The body will use protein as fuel only as a last resort when carbohydrates and fat sources have been depleted. Most excess protein is stored as body fat. Make sure you consult your registered dietician or health care professional on how much protein is necessary for you. The American Counsil on Exercise recommends a minimum of 50-70 grams per day. The average adult needs 0.8-1.0 grams of protein per kilogram of body weight per day. For atheletes 1.2-1.8 grams. Divide your weight by 2.2 to find your weight in kilograms.
