About half (45 to 54 percent) of patients seeking treatment for anorexia nervosa reported practicing some form of a vegan/vegetarian diet (Bardone-Cone, et al., 2012).
Bardone-Cone and colleagues (2012) found that 61 percent of current Eating Disorder individuals who have had a vegan/vegetarian diet said they believe there was a relationship between their Eating Disorder and choosing to be a vegan/vegetarian. These authors found veganism/vegetarianism in the history of about half of people who develop Anorexia Nervosa, and that more anorexia nervosa patients who were vegan/vegetarian struggled to complete Eating Disorder treatment (Bardone-Cone, et al., 2012).
