Well, I have a hard time saying anyone is too thin. As someone who follows a healthy lifestyle and exercises a lot, I'm in good shape and I also have a thin frame.
But what really bugs me about this thread is that if I opened up a thread that says "Don't you think she is too fat?" then I would be called names and the thread would be locked! It's okay to judge someone for being thin and saying she needs medical intervention, but it's not okay to judge someone for being fat? I believe overweight people need just as much help (psychological help, that is) as people who are anorexic.
