In Robbie's situation it doesn't really matter for reasons that you have just said. But when you are very serious about bodybuilding, everything has to be perfect for optimal results. Protein absorption has always been a highly debated topic in the world of teen bodybuilding and there's so much broscience involved.
Robbie only weighs 100lbs so he is obviously going to be really thin, doing loads of cardiovascular exercise will only burn more calories and if he doesn't eat more to compensate that he will lose even more fat. At that weight he really can't have much fat on him so he would look way more healthier if he was to gain some.
