I never seem to put on weight however much I eat. The more I ingest the more I egest. I'm over 6 foot and weigh less than 60 kilos... Good you say... Except that I'm a guy. I eat plenty. I stuff myself but I can't put on weight at all. Are there any foods or supplements that might help slow my metabolism? And eating fatty foods in excess is not an affective solution, I want a good weight but I don't want to take years off my life. Might it be worth seeing a GP too?
