Using Animal Research to Justify Eating Disorder Treatment Practices: Are We Going Too Far? (On Eating Junk Food in Treatment – Part II)

Liz 10 Comments

As a follow up to Charlene’s  post on eating hyper-palatable foods during eating disorder treatment , I asked Liz–SEDs’ resident expert on animal behaviour, particularly in relation to binge eating and drug addiction–to look at some of the studies that Julie O’Toole mentioned as evidence for Kartini Clinic’s guidelines of avoiding hyper-palatable foods for the first year of eating disorder recovery. If you missed Dr. O’Toole’s post, please do take a look. Here’s the main conversation that led to this post: 

In the comments, I asked Dr. O’Toole, 

I agree that eating cheetos and sugar-y drinks is ubiquitous but not exactly healthy, and I too question many versions of “normal eating” that people promote (and *everyone* has an opinion), but I wonder — if there’s any evidence for not allowing hyper-palatable foods to patients for a year? And what does the Kartini Clinic consider to be hyper-palatable? Why

The Benefits of Starving – Part II (Restricting Reduces Anxiety in Anorexia Nervosa)

Tetyana 10 Comments

What is different about anorexia nervosa sufferers that, in contrast to most dieters, enables them to maintain a persistent calorie deficit? Although no one can truthfully claim they know the full answer to that question, we do know that part of the answer most likely lies with serotonin (5-HT), a molecule that neurons use to communicate with each other.

I’ve written about serotonin in the context of anorexia nervosa before, so I’ll just do a brief summary of the important points here:

  • Serotonin has a lot of functions in the body; it plays a role in regulating appetite (satiety), sleep, mood, behaviour, learning and memory, and a variety of other things
  • Serotonin has been implicated in obsessionality, harm avoidance, and behavioural inhibition
  • Alterations in serotonin function have been linked to many disorders, including depression, OCD, anxiety, and eating disorders
  • Serotonin is made from tryptophan, an essential amino

Calorie Restriction, Anorexia Nervosa, and Memory Gaps

Tetyana 48 Comments

This post has been translated into Russian by Polina here.

I have often heard anorexia nervosa sufferers complain of “memory gaps,” particularly during the times they were really sick. As if they weren’t really there.  It can be scary and unnerving, to say the least. A few months ago, a Tumblr user asked me about this:

Hi Tetyana, I’m not sure if this is merely based on my own subjective experience of if there is any grounding at all, but I was wondering if there could perhaps be a link between EDs and a sort of memory loss. It’s hard to describe but I definitely seem to have huge “gaps” in my memory of during that time, as if I selectively block things out. I have limited inaccurate knowledge with regards to memory on a molecular/neurological basis so I do not know if there’s anything there. Perhaps with calorie
