The number of people becoming dangerously obsessed with healthy eating is growing, according to health experts.
Sufferers of the eating disorder, known as Orthorexia Nervosa, focus on maintaining a restricted diet rather than achieving a certain weight.
Whilst suffering from Orthorexia, Carrie Armstrong was eating only organic fruit and her weight dropped to six stone.
She told BBC Radio 5 live's Breakfast: "You think you're going to die. You think you're going to contaminate your body and it really rules your entire life."
