I'll tell you the problem with skinny right off the bat. Skinny does not necessarily mean healthy. The two are not interchangeable. A lot of us struggle with the pressure to have the "perfect" (a.k.a. skinny) body. I don't know any of my girlfriends who haven't complained about how they look. Nine times out of ten, one of us is almost always quoting Mean Girls when it comes to our looks. And nobody's complaint has ever been, "I have bad breath in the morning." Whatever, Cady. Who spells "Katie" like that anyways?
A lot of my classes this year emphasized the role the media plays in setting societal standards. Growing up, playing with my Barbies, I never thought I had to look like them. Who did I think I had to look like? Lizzie McGuire. Duh. And then when Hilary Duff went through her uber skinny stage (anybody else remember that?), suddenly I was like, "Oh, if Lizzie McGuire looks like that so should I." Granted at this point she was in her post-Lizzie days, but you get the point.
