Excessive, Obsessive, Compulsive? The Links Between OCD, OCPD and Excessive Exercise in Anorexia Nervosa

Excessive exercise played a big role in my eating disorder and, predictably, I am drawn to studies that look at the role excessive exercise plays in eating disorder symptomatology, course and outcome. This topic has captured the interest of many eating disorder researchers, with studies revealing that up to 80% of individuals with anorexia nervosa may exercise excessively (Davis et al., 1997), though others suggest more modest statistics, around 39% (Shroff et al., 2006; Tetyana wrote a post about this article here).

Scholars have also noted the potentially obsessive and compulsive nature of exercise among some individuals with eating disorders and have made the natural transition toward examining whether links exist between excessive exercise and obsessive-compulsive disorder (OCD) and/or obsessive-compulsive personality disorder (OCPD) traits (If you are confused about the difference between OCD and OCPD, click here).

Rigid food rules are very common among eating disorder sufferers. These rules can be about anything: the foods you are allowed to eat, how you are allowed to eat them, the time you are allowed to eat them, and so on.

But where do they come from? Why do some individuals have more rules and more ritualistic behaviours than others?

It is a complex question, but a recent study suggests that perfectionism might play a role. Specifically, the authors explored the idea that perfectionism mediates adherence to food rules in disordered eating behaviours. In order words, food rules might be a way in which perfectionism “expresses itself” in eating disorders.
