Ummm.... you wont add any muscle with no protein in your diet. With all that running your doing, your going to end up losing some muscle. If that is all your eating, that is barely any calories and you'll end up gaining weight over time sticking to that little of calories. Your diet is heading towards looking like a corpse man. If you want to add muscle, you need to consume around .8-1g of protein per pound of body weight.
