Protein, a macronutrient, is not a favorable source of energy for the body during exercise. While protein, fat and carbohydrates can all be used as sources of energy for the body, it is never a single macronutrient contributing one-hundred percent of the energy; but rather a percentage of each are being used all of the time and these percentages change according to activity type, intensity and even duration.
The range of total energy expenditure contribution of protein during exercise is about 5% (strenuous weight training) or up to 15% (during prolonged endurance exercise). Increased breakdown of protein during exercise is observed usually only when muscle glycogen has been depleted by 33-55%.
