hahaha same here, I think my metabolism too fast or something, I can eat whatever I eat, in as much quantity as I want yet nothing changes and if it does, it's not noticeable. On the downside this also means that when I work out its takes longer than for most to really show. But I really don't mind that since when I hit the gym it's mostly to get healthier and not to get too jacked!
The funniest part tho is that when I do workout, I eat even more than usual and end up being a threat to the fridge and to my wallet. lol :)
