Objective: Studies suggest that cognitive deficits and attentional biases play a role in the development and maintenance of obesity and eating disorders. In this study, we simultaneously examine attentional biases, as well as inhibitory control and mental flexibility, which are keys to controlling unwanted behaviors and thoughts in obese patients with and without binge eating disorder.
Methods: 16 obese patients with binge eating disorder and 16 patients without binge eating disorder were compared with 16 normal-weight controls on a "food/body-mental flexibility task", which allows the investigation of inhibitory control, mental flexibility and attention for stimuli related to the body and food.
Results: All obese patients made significantly more errors (i.e., pressing a key when a distracter displayed) and more omissions (i.e., not pressing a key when a target displayed) than controls in both food and body sections of the task. Obese participants with binge eating disorder made significantly more errors and omissions than those without binge eating disorder. No difference between groups was found concerning mental flexibility and cognitive biases for food- and body-related targets.
Discussion: These results suggest that obese patients have a general inhibition problem and difficulty focusing attention, which do not depend on the types of stimuli processed. The results also suggest that these cognitive deficits are more severe in obese patients with binge eating disorder, which indicates that there is a continuum of increasing inhibition and cognitive problems with increasingly disordered eating. These cognitive deficits may contribute to problematic eating behaviors.

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.

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).

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.

Background: OCD symptoms are well documented in anorexia nervosa (AN) and to a lesser extent in bulimia nervosa (BN), yet remain virtually unstudied in binge-eating disorder (BED).
Methods: In this cross-sectional observational study, 5927 participants with lifetime eating disorders (EDs) (i.e.
