In the 1980s, a few studies came out suggesting that patients with bulimia nervosa (BN) require fewer calories for weight maintenance than anorexia nervosa patients (e.g., Newman, Halmi, & Marchi, 1987) and healthy female controls (e.g., Gwirtsman et al., 1989).
Gwirtsman et al. (1989), after finding that patients with bulimia nervosa required few calories for weight maintenance than healthy volunteers, had these suggestions for clinicians:
When bulimic patients are induced to cease their binging and vomiting behavior, we suggest that physicians and dietitians prescribe a diet in which the caloric level is lower than might be expected. Our experience suggests that some patients will tend to gain weight if this is not done, especially when hospitalized. Because patients are often averse to any gain in body weight, this may lead to grave mistrust between patient and physician or dietitian.
Among many things, this ignores the fact … Continue reading →
Should eating disorder patients be introduced to “junk food” or “hyper-palatable” foods during treatment? A few days ago, I stumbled across a blog post where Dr. Julie O’Toole, Founder and Director of the Kartini Clinic for Disordered Eating, argues against introducing “junk food” during ED treatment. The crux of the argument is that “hyperpalatable foods”—e.g., chips and Cheetos—are not real food and should never be forced or encouraged for anyone, regardless of the presence of an eating disorder:
A lot of ink has been spilled on teaching Americans in general and children in particular to make good food choices. Just because you have anorexia nervosa as a child, and desperately need to gain and maintain adequate weight, does not mean that you will be immune from the health effects of bad eating as you get older. This is true whether or not you get fat later on. You can be

Anorexia nervosa was first described in the medical literature in 1689 by Richard Morton. It has been over 300 years since then and AN continues to be one of the deadliest psychiatric disorders. If not treated early, it runs the risk of becoming deeply entrenched and highly resistant to treatment.
Moreover, established treatments for related disorders like bulimia nervosa and depression, such as cognitive behavioural therapy and antidepressants, are rather ineffective in treating anorexia nervosa. Finally, even if significant physical and mental improvements are achieved in treatment, relapse rates for older individuals (even those in their 20s) remain high.
What makes anorexia nervosa so persistent and so hard to treat in individuals who develop it, particularly if it is not treated soon after onset? Why is recovery so hard?
In this paper, B. Timothy Walsh outlines a model based on cognitive neuroscience that attempts to answer these questions:
