As a whole, I would say women...But it really depends on the person! An immediate family member of mine (who is male) has an eating disorder that spiraled from being too overweight...Now he's too thin! We don't hear much about males who struggle with their weight, but they have a lot of pressure on them too. You see on tv shows bigger men with tiny little women, so it makes us believe men really have no reason to watch their weight...But I bet if I was a man watching women swoon over the ripped guys on Jersey Shore I'd be body conscience too! Lol (Not that I think they're that awesome looking...But men have a certain 'image' the media says they should fit in as well).
So I'm gonna go with women for the most part, but men aren't that far away!
