Weird eating habits.

Hmm... I don't know if this counts, but I have really bad/weird eating habits... I only eat if I'm hungry, and most of the time, I actually just forget to eat... So when I do eat, it's always at really weird times (usually in the middle of the night, since I'm a complete night owl) and junk food.... Mostly I just survive on caffeine (especially tea... lol)... Some days I do eat a ton though, and I don't seem to gain anything from it.. similarly, on days when I don't eat much/at all, I don't loose anything, so... Rather that 'eating without getting fat' it's more like I have really weird eating habits but my weight is never effected by it...(?)
...I don't think I have an eating disorder or anything, though, since my health in general doesn't seem to really suffer from it, and it's not like I deliberately decide not to eat because I see myself as 'fat' or particularly hate my weight or anything, so... I think it's all good. (I actually think it might be genetic, since my mother seems to be the same)
