Sad, but true - and not all that surprising. I came across this story on the Fat Lot of Good blog. I don't really have much to add, except what I already put in the blog's comments:
I wish I could say I was surprised reading this, but I’m not. Our societies obsess over and reward thinness, so I can see how it’s easy to rationalize doing whatever it takes to get thin. It’s sad and disheartening how pervasive this kind of thinking is.
