I was wondering how to overcome the problem of being underweight. Obviously I need to have my energy input at a higher level than my energy output, but I try really hard to do that and it doesn't seem to help. I eat a lot... a hell of a lot and I don't do rediculous amounts of excercise so that it would use up all of that energy, so I'm kinda lost for ideas. I eat healthly usualy aswell as eating junk... I just don't know what to do. Is there any advice you guys can give me, and is there anything that the Dr could or would do? I'm 6ft and only 135 pounds if that matters.
