I will also have to agree with these last few posts !! First off ... General doctors know nothing about good nutrition ... best they can do is advise on Vitamins ! They do not know anything about sports medicine as someone pointed out !
Secondly have you ever heard of cases of people overdosing on protein LOL !! If your body consumes too much it will just Piss it out ! END OF ! And if your looking to bulk up your going to need as much protein as you can get hold of !
a toned physique is a good starting point ! Now you just need to bulk / cut !
