Anorexia: it's a lifestyle not a disease. That's the view of the three young people who feature in this observational documentary. Part of the pro-anorexic world, they reject the idea of 'eating disorders', instead choosing to celebrate them as a lifestyle choice. For the first time this program investigates the underground network of pro-anorexic websites, which encourage people to raise their condition to an almost cult like status. It tackles head-on the extreme lifestyle of people with eating disorders, and what motivates younger people who choose to live their lives in this way.
