Objectives: The aim of this study was to determine the efficacy of cognitive-behavioral therapy (CBT) and behavioral weight loss treatment (BWLT) for overweight patients with binge eating disorder (BED).
Method: Eighty obese patients meeting criteria of BED according to DSM-IV-TR were randomly assigned to either CBT or BWLT consisting of 16 weekly treatments and 6 monthly follow-up sessions. Binge eating, general psychopathology, and body mass index (BMI) were assessed before, during, and after treatment, and at 12-month follow-up.
Results: At posttreatment results favored CBT as the more effective treatment. Analysis of the course of treatments pointed to a faster improvement of binge eating in CBT based on the number of self-reported weekly binges, but faster reduction of BMI in BWLT. At 12-month follow-up, no substantial differences between the two treatment conditions existed.
Conclusion: CBT was somewhat more efficacious than BWLT in treating binge eating but this superior effect was barely maintained in the long term. Further research into cost effectiveness is needed to assess which treatment should be considered the treatment of choice.

Comparing social stigma of anorexia nervosa, bulimia nervosa, and binge-eating disorder: A quantitative experimental study.
J Eat Disord
January 2025
University of South Australia, Justice & Society, Adelaide, South Australia, Australia.
Background: Currently, we know little regarding how stigma attributed to eating disorders compares to that of other psychological disorders and additionally within different types of eating disorders. In the current study, we aimed to explore the stigmatisation of eating disorders by comparing the stigma attributed to anorexia nervosa, bulimia nervosa, and binge-eating disorder, utilising depression as a comparative control.
Methods: A total of 235 participants from the general population were randomly assigned to an anorexia nervosa, bulimia nervosa, binge-eating disorder, or depression condition.
Appetite-Control and Eating-Behavior Traits Might Not Be Impacted by a Single Weight-Cycling Episode in Weight-Cycling Athletes: Results of the Wave Study.
Int J Sports Physiol Perform

Laboratory of the Metabolic Adaptations to Exercise Under Physiological and Pathological Conditions (AME2P) UPR 3533, CRNH Auvergne, Clermont Auvergne University, Clermont-Ferrand, France.
Purpose: The impact of weight cycling (WC)-successive weight loss (WL) and weight regain (WG)-on athlete performance is well documented, but effects on appetite are not. This study assessed the impact of a WC episode on dietary and appetitive profiles in athletes, considering sex and sport type.
Methods: Athletes (28 male, 20 female) from combat (n = 23), strength (n = 12), and endurance (n = 13) sports participated in 3 conditions during a WC episode (baseline, WL, WG).
Binge eating behaviours are associated with recurrent weight gain after metabolic and bariatric surgery.

Background: Recurrent weight gain (RWG) is a major post-operative challenge among metabolic and bariatric surgery (MBS) patients. Binge eating behaviours (BEB) and food addiction (FA) have been identified as significant predictors of post-MBS RWG. However, limited research has investigated their independent associations with post-MBS RWG.

Objective: This review maps existing literature on the prevalence of autism and ADHD in adult patients with Bulimia Nervosa (BN) and Binge Eating Disorder (BED); patient and stakeholder perspectives on this comorbidity; clinical differences in this population; and potential treatment adaptations or adjunct therapies. This is with the aim to inform future research priorities to improve clinical practice.
Method: As pre-registered, and following PRISMA guidelines, six databases (Embase, MEDLINE via Ovid, PsycINFO, Web of Science, CENTRAL, and Scopus) were searched for studies regarding autism and/or ADHD (diagnosed, probable, or traits) in adult patients with BN or BED.
