This is part II of posts on why I am highly skeptical of the argument that we need to understand the genetic basis of eating disorders in order to improve outcomes. If you would like to leave a comment, please read Part I as well.
I worry about the implications of focusing on genetics and neurobiology in identifying causes of and solutions to eating disorders in the context of a neoliberal society.
When I was an adolescent, finding out that eating disorders have a genetic component alleviated my guilt. Coming across Dr. Walter Kaye’s research into the neurobiology of eating disorders — the hypothesis that the drive to restrict may be linked to and reinforced by serotonin systems in the brain (here, here, and here) — provided me with a plausible biological explanation for why restricting made me feel calmer. It meant my eating disorder was … Continue reading →
I often hesitate to make broad, sweeping claims about the nature, cause, and experience of eating disorders and disordered eating. However, if there is one thing I feel absolutely certain saying about these disorders, it is that they are incredibly complex and multifaceted with no “one-size fits all” solution. So, I was quite excited when I came across a recent article by Michael Strober and Craig Johnson (2012) that explores the complexity of eating disorders and their treatment. Both authors have significant clinical experience treating eating disorders.
This article uses cases studies, literature, and the authors’ collective clinical experience to respond to some of the key controversies surrounding anorexia and its treatment. Among the major controversies that have come to light of late, they focus on two:
- Genetic/biological causation (Biologically-based mental illness – BBMI)
- Family-based treatment (FBT) as the best form of treatment for adolescents
The authors’ exploration of these … Continue reading →
Why do some people recover anorexia nervosa relatively quickly while others seem to struggle for years or decades? Does it depend on the person’s desire to get better? Their willpower? How much they are willing to fight? Is it just that some try harder than others? Some might say yes, but most will correctly realize that the picture is much, much more complex.
We can spend hours talking about barriers to treatment, but in this post I want to talk about something slightly different, something perhaps that is perhaps less “obvious.”
Suppose a group of girls–all roughly the same age, same illness duration, same socioeconomic background and race–enter the same treatment facility. What determines why some will do well in treatment and continue to do well after discharge, whereas others will relapse immediately after discharge, and yet others won’t respond to treatment at all? We know that catching eating … Continue reading →
I used to call them bingeing and purging marathons. If I binged and purged in the morning, chances were, I’d binge and purge throughout the day. The next time I’d eat, I was likely to end up–whether I wanted to or not–bingeing and purging. Not all individuals with bulimia nervosa binge and purge every day (or purge everything they eat, for that matter), but many do, and some binge and purge multiple times a day. In recovery, many people start by trying not to binge and purge before a certain time of the day–because once they binge and purge, it triggers a continuous cycle of bingeing and purging until they become to exhausted or otherwise end up going to bed.
I always wondered why that was, why was it so hard to keep a single episode of bingeing and purging from initiating a repeated cycle of bingeing and purging?

Excessive exercise (EE) is common among eating disorder patients. Indeed, in the study I’ll write about today, 39% of patients engaged in EE. Previous studies have tried to find psychopathological and personality correlates of EE but the results have been inconsistent. Some studies have suggested that impulsivity and addictiveness are highly correlated with EE whereas others found that anxious and depressive traits were more closely associated.
In a retrospective case series study involving outpatients with AN and BN, Penas-Lledo et al. found higher levels of anxiety and depression… among those who were identified as exercising excessively. The authors claimed that exercise might serve to reduce anxiety and stress in individuals with AN. In a similar study with adolescent inpatients with AN, Holtkamp et al. found that anxiety significantly predicted variance in exercise levels. These investigators proposed that anxiety symptoms in combination with food restriction contributed to increased levels

Anonymous asked, “I’ve never lost my period. Weight restored I am naturally thin, but even at a BMI of 15 or so I always got my period (although it wasn’t always regularly). This makes me feel like I’m not actually sick because I hear about everyone losing their period.”
eatruncats replied: “To the anon who asked about losing periods: For all the times she worries about not being sick enough because she never lost her period, there are people who lost their periods at BMIs of 18, 19, and 20 who worry about not being sick enough because they never got to a BMI of 15. If you have an eating disorder, you are “sick enough.” Period.“
As it stands now, amenorrhea–or the loss of three consecutive menstrual cycles–is a diagnostic criterion for anorexia nervosa. Individuals who have not lost their periods are diagnosed with eating disorder … Continue reading →
