I've searched around and I can't find very much on Peanut Butter. People say its a good protein source and whatnot, but what about using it to gain weight like milk in the GOMAD diet? I don't know anything about diet or exercise, but peanut butter and milk seem to be almost equal besides the extra fat in peanut butter. Is this a problem? What would the effects be if I ate 1 18 oz jar of peanut butter per day for a couple of months? I'm 5'10
