Objective: Binge-eating disorder (BED) is a prevalent, costly public health problem associated with serious functional impairments and heightened rates of psychiatric and medical comorbidities. Few evidence-based treatments are currently available for BED. We tested the effectiveness of cognitive-behavioral therapy (CBT), lisdexamfetamine (LDX), and combined CBT+LDX, for BED comorbid with obesity.

Article Synopsis
  • This study looked at the psychosocial and medical effects of body contouring surgery (BCS) on adults after they had bariatric surgery, focusing on those who wanted BCS to address loose skin.
  • Out of 56 participants, only 24 (42.9%) actually underwent BCS, mainly due to insurance issues or financial constraints, while those who did not have BCS reported more medical and psychosocial problems related to loose skin.
  • The findings suggest that concerns about loose skin significantly impact mental health and overall well-being, indicating the need for more attention to these issues after bariatric surgery.

Article Synopsis
  • This study looked at how well a medication called lisdexamfetamine (LDX) works for people with binge-eating disorder (BED) after they had a successful initial treatment.
  • Sixty-one adults took part, and they were split into two groups: one group took LDX while the other got a placebo (a fake pill) for 12 weeks.
  • Results showed that fewer people who took LDX returned to binge eating compared to those who took the placebo, and the LDX group also lost weight, while the placebo group gained weight.

Objective: To explore dietary-restraint as a mediator of binge eating and weight-loss outcomes within a randomized controlled trial comparing cognitive-behavioral therapy (CBT) and behavioral weight loss (BWL) for binge-eating disorder (BED) with obesity.

Methods: Ninety participants were randomly assigned to CBT or BWL and assessed by evaluators blinded to conditions at pretreatment, throughout-, and post-treatment (6 months). Three dietary-restraint measures (Eating Disorder Examination-Questionnaire [EDE-Q]-Restraint, Three-Factor Flexible-Restraint and Rigid-Restraint) were administered at pretreatment and after 2 months of treatment.

Objective: Adults with binge-eating disorder (BED), compared with those without BED, demonstrate higher blood-oxygen-level-dependent (BOLD) response to food cues in reward-related regions of the brain. It is not known whether cognitive behavioral therapy (CBT) can reverse this reward system hyperactivation. This randomized controlled trial (RCT) assessed changes in BOLD response to binge-eating cues following CBT versus wait-list control (WLC).

Objective: To test whether overvaluation of shape/weight at the end of treatment prospectively predicts relapse at 12-month follow-up in patients with binge-eating disorder (BED).

Method: Participants were 129 patients with BED who achieved abstinence from binge eating after 6 months of behaviorally-based weight-loss treatments in a clinical trial. Independent assessments conducted at posttreatment and at 12-month follow-up included the Eating Disorder Examination interview, the Beck Depression Inventory, and weight measurements.

Objective: Psychometric studies evaluating the reliability of eating-disorder assessment among individuals with binge-eating disorder (BED) have been limited. The current study documents the interrater reliability and internal consistency of the Eating Disorder Examination (EDE) interview when administered to adults with Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) (DSM-5)-defined BED.

Methods: Participants (N = 56) were adults seeking treatment for BED in the context of clinical trials testing pharmacological and psychological treatments.

Objective: Parental eating disorders are associated with disordered eating behaviors and psychopathology in their children, but it is not known whether parent treatment for binge-eating disorder (BED) is associated with changes in child disordered eating behaviors and weight. Benefits or the "ripple" effect of treatment on untreated family members has been described in the obesity literature but not for BED.

Method: Participants evaluated for two randomized clinical trials for BED were screened for whether they had children.

Specific psychological treatments have demonstrated efficacy and represent the first-line approaches recommended for anorexia nervosa, bulimia nervosa, and binge-eating disorder. Unfortunately, many patients, particularly those with anorexia nervosa, do not derive sufficient benefit from existing treatments, and better or alternative treatments for eating disorders are needed. Less progress has been made in developing pharmacologic options for eating disorders.

Background: While some bariatric surgery outcomes vary by race/ethnicity, less is known about racial/ethnic differences in loss-of-control (LOC) eating and psychosocial outcomes post-surgery.

Objective: This prospective study examined and extended initial short-term findings regarding racial differences in post-bariatric surgery LOC eating and weight loss to longer-term outcomes through 24-month follow-ups.

Setting: Academic medical center in the United States.

Background: Metabolic and bariatric surgery (MBS) is the most effective and durable obesity treatment. However, there is heterogeneity in weight outcomes, which is partially attributed to variability in appetite and eating regulation. Patients with a strong desire to eat in response to the reward of palatable foods are more likely to overeat and experience suboptimal outcomes.

Background: Postoperative loss-of-control (LOC) eating is associated with eating-disorder psychopathology, poorer weight loss, and mental health outcomes following bariatric surgery. The nature and significance of shape discrepancy has not been examined in patients with LOC eating following bariatric surgery.

Objectives: To examine shape discrepancy, WBI (weight bias internalization) and ED (eating-disorder) psychopathology in patients with LOC eating after bariatric surgery.

Article Synopsis
  • The study investigated the efficacy of the combined medication naltrexone/bupropion for treating binge-eating disorder (BED), particularly among individuals with obesity.
  • In a 12-week trial with 89 participants, the results showed that while there were no significant reductions in binge-eating frequency compared to placebo, naltrexone/bupropion led to greater weight loss.
  • Overall, the findings indicated that naltrexone/bupropion is not effective in reducing binge eating but is beneficial for weight loss in patients with BED, regardless of their obesity status.

Background: Modest weight losses may be associated with improvements in cardiovascular disease risk factors (CVDRF) in patients with obesity. The effects of weight losses on CVDRF in persons with binge-eating disorder (BED) are unknown. This study prospectively examined changes in CVDRF among patients receiving behaviorally-based weight-loss treatment (BBWLT) who attained modest weight losses (≥5 to <10% and ≥10%).

Purpose Of Review: Binge-eating disorder (BED) is a serious psychiatric problem associated with substantial morbidity that, unfortunately, frequently goes unrecognized and untreated. This review summarizes the current status of behavioral, psychological, pharmacological, and combined treatments for BED in adults with a particular focus on recent findings and advances.

Recent Findings: Certain specific psychological treatments, notably CBT and IPT, and to some extent DBT, have demonstrated efficacy and are associated with durable benefits after treatment.

Article Synopsis
  • The study investigates the effectiveness of naltrexone/bupropion as a maintenance treatment for binge-eating disorder (BED) in patients who previously responded well to acute treatment, addressing the issue of relapse when treatment is stopped.
  • Conducted over four years with 66 participants, the trial found that those on naltrexone/bupropion had a higher rate of binge-eating remission (68.8%) compared to those on placebo (50.0%), along with lower binge-eating frequency and weight loss.
  • The results suggest that maintaining treatment with naltrexone/bupropion can be beneficial for adults with BED and obesity, supporting the prevention of relapse and promoting

This study examined baseline patient characteristics as predictors of early weight loss, defined as any weight loss within the first month of treatment, among patients receiving adjunctive behavioural treatments for loss-of-control (LOC) eating about 6 months after bariatric surgery. Participants were 126 patients in a treatment trial for LOC-eating (roughly 6 months postoperatively) categorized by early weight change following 1 month of treatment. Early weight-loss, defined as any weight loss following 1 month of treatment, and weight-gain, defined as any weight gain, groups were compared on sociodemographic and clinical variables assessed using a battery of reliably administered diagnostic and clinical interviews and established self-report measures, and on surgery-related variables (time since surgery, percent total [%TWL], and percent excess weight loss).

Objective: Certain treatments have demonstrated acute efficacy for binge-eating disorder (BED) but many patients who receive "evidence-based" interventions do not derive sufficient benefit. Given the dearth of controlled research examining treatments for patients who fail to respond to initial interventions, this study tested the efficacy of cognitive-behavioral therapy (CBT) for patients with BED who do not respond to initial acute treatments.

Methods: Prospective randomized double-blind placebo-controlled single-site trial, conducted August 2017-December 2021, tested 16-weeks of therapist-led CBT for non-responders to initial treatment (naltrexone/bupropion and/or behavioral therapy) for BED with obesity.

Objective: Binge-eating disorder involves overeating while feeling a loss of control (LOC). Emotions around LOC appear to vary; some patients fear LOC whereas others feel powerless or "resigned" to LOC. This study examined differences in psychopathology among treatment-seeking patients with binge-eating disorder categorized with fear of LOC, resignation to LOC, and no fear/resignation of LOC.

Background: Assessment of eating disorder psychopathology during preoperative psychological evaluations could be facilitated with psychometrically valid measures. One of the most commonly used measures, the Eating Disorder Examination Questionnaire (EDE-Q), is lengthy and has been found to have psychometric limitations. Research has identified a shorter version that has received reliable support across diverse samples but requires further validation for use with patients being evaluated for bariatric surgery.

Objective: A sizeable minority of patients with binge-eating disorder (BED) do not fully respond to evidence-based treatments. Evidence to guide refinements of treatments is needed. Conceptualizing BED as arising from a network of symptom-to-symptom interactions allows for identification of the most strongly connected symptoms, which could inform intervention targets.
