You can never be too thin?

Thanks to HoutLust for drawing my attention to a pretty hard hitting new campaign from the Eating Disorders Association. You can see the ad on the Houtlust site, which depicts tips from pro-anorexia websites and aims to raise awareness in parents and carers who often miss the signs of eating disorders in their kids. Even after working in the field for many years, I found this a shocking campaign. I've always felt ambivalent about discussing pro-anorexia sites on this site for fear of giving them more fuel, but I can see that the aim of the campaign is an honorable one. I'd be interested to hear other people's views.
