this is not a subject us guys speak up about very often, maybe because we feel it's none of our business, but i'm going to pull the "i have my own history of weight issues" card here and talk about it anyway...
a lot of people seem to think that the girl to the left in this chart is the one with the ideal body weight, when in reality, she's slightly malnourished.
people who are thin as bones and close to anorexia get an unhealthy amount of positive attention in the media. and i don't understand why.
as a man, i woudn't really think of a girl as fat unless she looked like number 4 from the left. number 3 just looks like she has a relaxed attitude, which i feel is attractive in its own way.
aside from the horrible beautify standards that the media pushes on us these days, i imagine that girls must get a lot of abuse from toxic people to feel this insecure.
