They're called pro-eating disorder Web sites. And many teens looking to lose weight -- even those who don't need to -- are logging on to these communities of individuals who engage in dangerous eating habits. Yet many parents aren't aware the sites even exist and that their children are visiting them, researchers have found. Complicating matters, "pro-recovery" sites that promote recovery from eating disorders can also be a source of weight-loss or purging techniques, the researchers found.
