How much do you weigh...how hard do you lift and how much above maintenance are you? The higher over maintenance the less protein (comparatively) you need simply because excess carbs and fat will protect you from using protein as energy. The reason you don't only eat protein is just that. If you are lacking in carbohydrate and fat as energy sources protein/whether muscle or ingested will be used as energy. However, protein is less efficient as an energy source and if all you eat is protein, you pretty much feel like ass.
