Authorities from Loyal Health Care at Royal Hospital, Cheshire, want the campaign to make people more aware of the dangers of sites that promote eating disorders. Top among the list is xanga.com

Loyal Health Care also wants internet service providers and social networks such as Facebook, MySpace, Digg, Technorati to closely monitor sites that promotes anorexia. Over 1.1 million British suffer from anorexia with 93% being women, although experts say this number is higher as many cases go undiagnosed.

The rise of the internet and new media has played a significant role in the increase in people with eating disorders, with xanga.com providing easier access to information on how to get thin.

A recent study found that young women exposed to pro-anorexia websites subsequently felt more negative, had lower self-esteem, perceived themselves as heavier and were more likely to compare their bodies with other women.

People with eating disorders are extremely vulnerable and often have very low self esteem, so these pro-anorexia blogs and websites on xanga could do a severe harm considering they give terrible way on losing weight.

Danielle Clark, a cured anorexia patient suggested that xanga.com must prohibit and close all blogs that promotes pro anorexia content.
