Brain responds differently to food rewards in bulimia nervosa

(University of California - San Diego) Researchers at University of California San Diego School of Medicine have discovered differences in how the brain responds to food rewards in individuals with a history of bulimia nervosa (BN), an eating disorder characterized by frequent episodes of binge eating followed by efforts of purging to avoid weight gain. The findings further define specific brain mechanisms involved in eating disorders and could help lead to new treatment therapies.

DiscussionThese data provide one possible explanation for the inconsistent findings regarding the trajectory of negative affect after binge eating. Moreover, they suggest that the findings from previous studies are not necessarily contradictory, but may be complementary, and appear to bolster support for the affect regulation model of binge eating.

These questions address the importance of the research area. ‘FA’ can be measured with the latest Yale Food Addiction Scale 2.0 questionnaire. Current research found a broad overlap of 'FA' and classic eating di sorders like bulimia nervosa. This presentation will update those findings and discuss the underlying mechanism.

Abstract Bulimia nervosa and anorexia nervosa are inextricably linked, with substantial clinical and epidemiological overlaps. Yet, while anorexia has been analyzed extensively in medical anthropology, bulimia remains under-theorized. This is, perhaps, because, compared to self-starvation, binge eating presents a logic of practice that is difficult to reconcile with culturally reified notions of self-control, transcendence, and hard work. Thus, although anthropologists have analyzed anorexic subjectivities as imbued with a sense of cleanliness and purity, moral superiority, and heroics, similar analyses have not b...

I’d like to talk to you about To the Bone, a movie which was released on Netflix this July. To the Bone deals with eating disorders (“EDs”) and has caused quite a stir across social media ever since its trailer was released. Though I won’t go into much detail in this article, note that there will be a few spoilers ahead. You should also note that To the Bone contains potential triggers — as do the heated responses to it on the social media. So check in with yourself regularly, as I ended up needing to do, if you decide to watch the film and participate in those debates afterwards. To the Bone ...

Americans spend billions of dollars on weight loss and workout programs in order to try to achieve the “perfect body.” Advertisements promise confidence, improved self-esteem, impeccable health and romance once the perfect body is achieved. The myth that we are presented with is that we are just not trying hard enough if we aren’t thin.   The ads, and even our healthcare system, do not acknowledge the scientific evidence that body size and shape are under significant genetic control. Body composition is a lot more complex than simply calories-in and calories-out.    What is body image? &nbs...

Abstract Network analysis has recently been introduced as a clinically relevant methodology for understanding the structure of mental disorders and for evaluating cognitive behavioral models of psychopathology. The current study uses network analysis to validate the transdiagnostic model of eating disorders by examining the association between overvaluation of shape and weight and eating disorder symptoms. Eating disorder symptoms were measured among a sample of 194 treatment-seeking children, adolescents, and adults presenting to an outpatient eating disorder clinic. We created transdiagnostic and disorder-specif...
