Why are girls always so worried about being skinny?

Because that is the what the majority of men like.

most girls look at other girls who are skinny and think " i want to be like that" but the problem is that the skinny girls do this and they think the skinny person there compareing themself to is skinnyer than them, no matter how much weight they loose they still tend to think this . they think that bacause all the guys like her and they need to be like that in order for guys to like them!! but that's not true. they get so presured buy magazines an t.v because guys are always comenting on whos hott in them they want to be like that.
