The Truth About Online Anorexia - on Thursday 9th April ITV1 9.00pm

Fearne Cotton examines the ongoing trend for super-slim women and immerses herself in the worrying world of 'pro-ana' websites who encourage anorexia and starvation as a life choice.

Follow up:

As Cotton explores the diet and exercise regime of a 'pro-ana', she'll try some of the extreme regimes that they endorse and meet other girls who've embraced the same lifestyle. She will explore the seductive nature of these 'support' groups, examine the world of competitive dieting, and look at relationships that ordinary women have with each other when it comes to diet and body image.

Cotton also meets a mother who lost her teenage daughter to the illness, and talks to an anorexia survivor, as well as Marjorie Wallace of mental health charity SANE, and a young woman who runs a 'pro-ana' website.
