What is disordered eating and how is it different from an eating disorder?

Eating behaviours can be described within a spectrum from optimal eating to eating disorders, with disordered eating sitting somewhere in the middle. Disordered eating can include normalised eating behaviours such as skipping meals, overeating, undereating, binge eating and extreme dieting. It can also include other behaviours associated such as obsessive or excessive exercise.

Eating disorders, on the other hand, are diagnosable conditions characterised by persistent and extreme disturbances in eating behaviour. There are different types of eating disorders such as anorexia nervosa, bulimia nervosa, binge eating disorder, Avoidant Restrictive Food Intake Disorder (ARFID) and others. Eating disorders are accompanied by intense negative thoughts, feelings and behaviours towards food, weight and body image. 

In summary, disordered eating is a more general term that encompasses a broad range of eating behaviours, while eating disorders refer to specific, diagnosed conditions with specific symptoms and criteria.
