Political Bodies: What is the Impact of National or Regional-Level Eating Disorder Prevention?

Andrea 1 Comment

When it comes to prevention, I’ve noticed a strong interest in working toward large-scale prevention initiatives. I’ve written about prevention before, noting the potential for unintended effects, as well as schoolgirls’ reactions to and acceptance of prevention interventions (here). But what about the larger scale efforts to prevent body image concerns and eating disorders?

Countries from the US to Australia to Israel have taken strides to implement initiatives aimed at improving national body image (a lofty goal? Perhaps.); you might have heard about bans on thin runway models and airbrushing, among other efforts. We know that eating disorders are not solely caused by thin-ideal internalization or bad body image; in fact, body image might not even be that useful of a concept for everyone, as I wrote about here.

However, improving body satisfaction could be a useful end goal in and of itself. Why not … Continue reading →

Polar Opposites? The Social Construction of Bulimia and Anorexia Nervosa

Andrea 10 Comments

Some might argue that bulimia nervosa is more “hidden” than anorexia nervosa — it is not always obvious that someone is suffering from bulimia (though, I would argue, it is not always obvious that someone is suffering from any eating disorder). Even when it is “discovered,” BN is often placed in opposition with AN — as if the two were polar opposites.

Indeed, attempts to define a phenotype (a set of observable traits or characteristics) for AN and BN tend to oppose the two and to suggest that the people who develop AN are inherently different from those who develop BN. While I believe there is some scientific evidence for personality differences between the two, the degree of diagnostic crossover and symptom variability in eating disorders makes me feel like this split is at the very least overly simplistic.

What is interesting is how BN has come to occupy a … Continue reading →

Energy Expenditure in Anorexia Nervosa Patients

Tetyana 7 Comments

How many calories do patients with anorexia nervosa need to eat to gain a kilo (2.2 lbs)? It seems like a simple question and one that we should have figured out a long time ago, given the importance (err, necessity) of refeeding and weight restoration in recovery from anorexia nervosa.

Unfortunately, research in this area has often led to contradictory results (see Salisbury et al., 1995 and de Zwaan et al., 2002 for reviews). Fortunately, a paper by Stephan Zipfel and colleagues (2013, freely available here) sheds light on one potential cause of the discrepancies.

But first, some definitions:

TDEE stands for total daily energy expenditure. TDEE has three components: resting energy expenditure (REE), dietary-induced thermogenesis (DIT), and activity-induced thermogenesis (AIT). The gold standard for measuring TDEE is through something called the doubly labelled water technique. REE is usually measured through indirect calorimetry. (These techniques were used in this … Continue reading →

Disordered Eating and Athletic Performance: Where’s the Line?

Emma 4 Comments

If a person severely restricts his diet and exercises for hours each day, he has an eating disorder. If another does exactly the same but it is because she wants to make the lightweight rowing team (which has an upper weight limit), she’s a committed athlete. When the two overlap, and an athlete presents with eating disorder symptoms, how do we distinguish between the demands of the sport and the illness?

I’ve been interested in the distinctions we make between disordered and non-disordered eating and exercise behaviours for a while now. Recently, when I was browsing through articles, I came across a literature review by Werner et al. (2013) (open access) of studies examining weight-control and disordered eating behaviours in young athletes.

The authors start by noting the sheer lack of research that has actually been done in this area. This is worrying: typical onset of eating disorders is during … Continue reading →

Reflecting on the 2014 International Conference on Eating Disorders

Andrea 1 Comment

Tetyana’s Note: Instead of writing two separate posts, I’ve decided to interject and add my own thoughts/opinions to Andrea’s post. For one, I think this will reduce repetition and I think it will be better to have any differing opinions in one place (I think this will facilitate discussion, I hope).  I will clearly mark my own comments so that they are not for conflated with Andrea’s. If I don’t comment it is because I wasn’t there, have nothing to add, or completely agree and thus have nothing/little to add. Admittedly, I’m going to focus more on things I didn’t like because I think it is important to talk about how the field can improve. – Tetyana

I am finally writing down some thoughts and reflections from ICED after taking a week to marinate on the proceedings and to grade a lot of papers. I love going to conferences — … Continue reading →
