Recovering from an Eating Disorder in a Society that Loves Fat Shaming (and Dieting)

Tetyana 3 Comments

Is ED recovery easier when your body is “normative or stereotypically desirable”? The anon asking the question implied that recovery could be more difficult because “an obese person … will never stop hearing hearing extremely triggering stuff about their body type.” Anon asked, “Have there been any studies on this?” Andrea tackled this question in her last post (it might be helpful to read it first if you haven’t yet); in this post, I will expand on my original answer.

Assuming anon meant, “Have there been anything studies assessing whether recovery is harder for individuals who do not fit the normative body type (because of fat phobia/fat shaming/diet culture)?” Then, my answer is: Not really, or at least I couldn’t find anything evaluating this question directly.

I was only able to find a few studies commenting on the history of overweight or obesity as a predictor of recovery/treatment … Continue reading →

Factors Associated with Recovery from Anorexia Nervosa

Tetyana 18 Comments

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 →

Demystifying the Genetics of Eating Disorders – Part II

Tetyana

In my last post I talked about some methods that scientists use to study the genetics of eating disorders. I focused on a subfield of genetics called behavioural genetics (which you can think of as a field that attempts to understand, in part, the interplay of genetics and environment in behaviour). In this post I’ll shift gears and focus on molecular genetics. I’ll be working of the same review paper by Drs. Zerwas and Bulik (2011). Molecular geneticists study the structure and function of genes on a molecular level. For example, they try to understand how different mutations or alterations in the genetic code can affect protein function and lead to disease states.

GENETIC ASSOCIATION STUDIES

Genetic association studies are hypothesis driven. This means that researchers make a list of genes that are known to be involved in biological mechanisms or behaviours that are affected in eating disorders, such … Continue reading →

Demystifying the Genetics of Eating Disorders – Part I

Tetyana 9 Comments

Today I thought I’d take the time to do an overview of what researchers know about the genetics of eating disorders and try to clear up some common misconceptions. The bulk of the content in this blog post comes from a very nice review paper published in 2011 by Drs. Stephanie Zerwas and Cynthia Bulik on the genetics and epigenetics of eating disorders. In an effort to keep blog posts short, this will be a multi-part mini-series.

When it comes to the genetics of eating disorders, there are two main questions that research ask: What is the relative contribution of genetic factors to eating disorder behaviours? And what are those genetic factors? I’ll talk about research attempting to answer the first question in this post and the second question in my next post.

In order to understand the role that genetics plays in influencing eating disorder behaviours, researchers use family, … Continue reading →
