Disordered eating can include behaviours which reflect many but not all of the symptoms of feeding and eating disorders such as Anorexia Nervosa, Bulimia Nervosa, Binge Eating Disorder, Other Specified Feeding and Eating Disorders (OSFED) or Avoidant/Restrictive Food Intake Disorder (ARFID).

Disordered eating behaviours, and in particular dieting are the most common indicators of the development of an eating disorder. Eating disorders are severe and life threatening mental illnesses. An eating disorder is not a lifestyle choice.
