Integrated weight loss and cognitive behavioural therapy (CBT) for the treatment of recurrent binge eating and high body mass index: a randomized controlled trial

Dismantling the myth of "all foods fit" in eating disorder treatment

We call for a reevaluation of the long-standing dogmatic nutritional principle that "all foods fit" for all cases of eating disorders (EDs) and its corollary, "there are no bad foods" (for anyone ever) during ED treatment. Based on accumulated scientific research, we challenge these ideologies as outdated, confusing, and potentially harmful to many patients. We review the evidence that indicates the folly of these assumptions and show there are a variety of exceptions to these rules, including (1) food allergies, sensitivities, and intolerances, (2) religious and spiritual preferences or doctrines, and (3) the ubiquitous emergence and widespread availability of ultra-processed foods leading to the potential development of addiction-like eating and a higher prevalence of various medical and psychiatric comorbidities, as well as higher mortality. This evidence supports a nutritional psychiatry approach that should be integrated into (rather than dissociated from) ED treatment research and practice.

Eating disorders and obesity: bridging clinical, neurobiological, and therapeutic perspectives

Eating disorders (EDs) and obesity are complex health conditions sharing various risk and maintenance factors, intensified in cases of comorbidity. This review explores the similarities and connections between these conditions, examining different facets from a multidisciplinary perspective, among them comorbidities, metabolic and psychological factors, neurobiological aspects, and management and therapy implications. We aim to investigate the common characteristics and complexities of weight and EDs and explore their interrelationships in individuals who experience both. The rising prevalence of EDs in people with obesity necessitates integrated approaches to study this comorbidity and to identify and analyze both common and distinct features of these conditions. This review may offer new opportunities for simultaneous prevention and management approaches, as well as future lines of research.

Eating Disorder Symptomatology Among Young Adult Cigarette and E-Cigarette Users

Objective: Tobacco use is elevated among individuals with eating disorders (EDs). Yet, further research is needed to understand associations between cigarette and e-cigarette use patterns and ED symptomatology. To gain a more comprehensive understanding of tobacco use and EDs, this study characterized ED symptomatology and tobacco use patterns, including exclusive cigarette use, e-cigarette use, dual use, and nonuse. Method: Young adults aged 18-24 years who self-reported exclusive cigarette, e-cigarette, dual, or nonuse (N = 2500) were recruited via Lucid, an online survey management company. Participants completed questionnaires assessing body dissatisfaction, global ED psychopathology, binge eating and self-induced vomiting frequency, and demographics. ED diagnostic groups included: anorexia nervosa (AN), bulimia spectrum eating disorders (BSED), atypical AN, and night eating syndrome (NES). Results: Multinomial logistic models revealed those with AN were more likely to be dual users, those with atypical AN were more likely to be exclusive e-cigarette users, and participants with a BSED or NES were more likely to be exclusive e-cigarette or dual users, compared to those without an ED. General linear models suggested body dissatisfaction and global ED psychopathology were higher among exclusive e-cigarette and dual users, while binge eating and self-induced vomiting frequencies were greater among all tobacco use groups compared to nonusers. Discussion: Our findings suggest young adults with ED symptomatology were more likely to be users of e-cigarettes exclusively or dual users. It will be necessary to examine how these associations manifest using longitudinal and clinical populations in future research.

Improvements in cardiovascular disease risk factors associated with modest weight loss following treatment in patients with binge-eating disorder and obesity

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%).

METHOD

Of 191 participants, CVDRF variables were re-assessed in 168 participants at posttreatment and in 151 at 12-month follow-up. Participants who attained ≥5 to <10% weight loss were compared to those who did not on CVDRFs (total cholesterol, HDL, LDL, triglycerides, HbA1C, mean plasma glucose, heart rate, and systolic/diastolic blood pressure); similar comparisons were completed for those who attained ≥10% weight loss.

RESULTS

At posttreatment, ≥5 to <10% weight loss (N = 42; 25.0%) was associated with significant improvements in HbA1c and mean plasma glucose, whereas ≥10% weight loss (N = 40, 23.8%) was associated with significant improvements in total cholesterol, triglycerides, HbA1c, mean plasma glucose, and heart rate. At 12-month follow-up, ≥5 to <10% weight loss (N = 17; 11.1%) was related to significant improvements on HDL, triglycerides, HbA1c, and mean plasma glucose, whereas ≥10% weight loss (N = 40, 26.0%) was associated with significant improvements on all the CVDRF variables (except blood pressure).

CONCLUSIONS

Modest weight loss is associated with significant improvements in CVDRFs in patients with BED and obesity following treatment and at 12-month follow-up. Future work should examine whether improvements in CVDRF are attributable to weight loss per se and/or to other related lifestyle changes.

PUBLIC SIGNIFICANCE STATEMENT

Individuals with binge-eating disorder and obesity who attain modest weight loss following treatment exhibit improvements in various measures of cardiovascular disease risk compared to those who do not. While weight loss has been challenging for individuals with binge-eating disorder, clinicians should inform patients of the potential health benefits of modest weight loss. Future research should investigate whether weight loss itself and/or related behavioral lifestyle changes drive improved cardiovascular disease risk factors.

Is binge eating associated with poor weight loss outcomes in people with a high body weight? A systematic review with meta-analyses

OBJECTIVES

This systematic review aimed to compare the weight change in people with or without binge eating who underwent various weight loss treatments.

METHODS

We searched for studies in PubMed, American Psychological Association, and Embase from inception to January 2022. The studies selected included assessment of binge eating and body weight before and after weight loss treatment in people of any age. The meta-analyses were conducted using Comprehensive Meta-Analysis (CMA). We used Egger's regression test, the funnel plot, and the Trim and Fill test to assess the risk of publication bias.

RESULTS

Thirty-four studies were included in the systematic review, with a total of 10.184 participants. The included studies were divided into three categories according to types of weight loss treatments, namely, (1) bariatric surgery; (2) pharmacotherapy isolated or combined with behavioral interventions; and (3) behavioral and/or nutritional interventions. The meta-analyses showed no significant difference in weight loss between people with or without binge eating engaged in weight loss treatments, with an overall effect size of - 0.117 (95% CI - 0.405 to 0.171; P = 0.426).

CONCLUSIONS

Our findings showed no difference in weight loss in people with or without pre-treatment binge eating who received various weight loss treatments. Weight loss treatments should not be withheld on the basis that they will not be effective in people with pre-treatment binge eating, albeit their safety and longer term impacts are unclear.

LEVEL OF EVIDENCE

Level I, at least one properly designed randomized controlled trials; systematic reviews and meta-analyses; experimental studies.

Psychotherapies for eating disorders: findings from a rapid review

BACKGROUND

Psychotherapy is considered central to the effective treatment of eating disorders-focusing on behavioural, psychological, and social factors that contribute to the illness. Research indicates psychotherapeutic interventions out-perform placebo, waitlist, and/or other treatments; but, outcomes vary with room for major improvement. Thus, this review aims to (1) establish and consolidate knowledge on efficacious eating disorder psychotherapies; (2) highlight select emerging psychotherapeutic interventions; and (3) identify knowledge gaps to better inform future treatment research and development.

METHODS

The current review forms part of a series of Rapid Reviews published in a special issue in the Journal of Eating Disorders to inform the development of the Australian-government-funded National Eating Disorder Research and Translation Strategy 2021-2031. Three databases were searched for studies published between 2009 and 2023, published in English, and comprising high-level evidence studies (meta-analyses, systematic reviews, moderately sized randomised controlled studies, moderately sized controlled-cohort studies, and population studies). Data pertaining to psychotherapies for eating disorders were synthesised and outlined in the current paper.

RESULTS

281 studies met inclusion criteria. Behavioural therapies were most commonly studied, with cognitive-behavioural and family-based therapies being the most researched; and thus, having the largest evidence-base for treating anorexia nervosa, bulimia nervosa, and binge eating disorder. Other therapies, such as interpersonal and dialectical behaviour therapies also demonstrated positive treatment outcomes. Emerging evidence supports specific use of Acceptance and Commitment; Integrative Cognitive Affective; Exposure; Mindfulness; and Emotionally-Focused therapies; however further research is needed to determine their efficacy. Similarly, growing support for self-help, group, and computer/internet-based therapeutic modalities was noted. Psychotherapies for avoidant/restrictive food intake disorder; other, and unspecified feeding and eating disorders were lacking evidence.

CONCLUSIONS

Currently, clinical practice is largely supported by research indicating that behavioural and cognitive-behavioural psychotherapies are most effective for the treatment of eating disorders. However, the efficacy of psychotherapeutic interventions varies across studies, highlighting the need for investment and expansion of research into enhanced variants and novel psychotherapies to improve illness outcomes. There is also a pressing need for investigation into the whole range of eating disorder presentations and populations, to determine the most effective interventions.

Binge-Eating Disorder Interventions: Review, Current Status, and Implications

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. Certain specific lower-cost scalable interventions, notably CBTgsh, have demonstrated efficacy and have potential for broader uptake. An important advance is the emerging RCT data indicating that BWL, a generalist and available behavioral lifestyle intervention, has effectiveness that approximates that of CBT for reducing binge eating and eating-disorder psychopathology but with the advantage of also producing modest weight loss. There exists only one pharmacological agent (LDX) with approval by the FDA for "moderate-to-severe" BED. Research with other "off label" medications has yielded modest and mixed outcomes with a few medications statistically superior to placebo over the short-term and almost no longer-term data. Nearly all research combining medications and psychological treatments has failed to enhance outcomes (combined appears superior to pharmacotherapy-only but not to psychotherapy-only). Many people with BED suffer in silence and shame, go untreated, and rarely receive evidence-based treatments. Patients and practitioners need to recognize that research has identified several effective interventions for BED, and these can work quickly for many patients. Future research should identify treatments for those who do not derive benefit from initial interventions, identify additional pharmacological options, test agents with relevant mechanisms of action, and utilize innovative adaptative "SMART" designs to identify treatments to enhance outcomes among initial responders and to test alternative treatments to assist initial non-responders.

Evaluation of a combined, online intervention for binge-type eating disorders and high body weight in young adults

BACKGROUND

Binge-type eating disorders (EDs; i.e., bulimia nervosa, binge eating disorder) are common among young adults with high body weight, yet few interventions target both conditions. This study tested an online guided self-help intervention that provided cognitive behavioral therapy (CBT) tools for EDs and behavioral weight loss (BWL) content to young adults with binge-type EDs and high body weight.

METHOD

60 adults aged 18-39 with clinical/subclinical binge-type EDs and high body weight were randomized to a combined condition or a CBT-only condition. Participants received self-help content for 8 weeks and self-reported ED attitudes, frequency of binge eating and compensatory behaviors, and weight at baseline, 4-weeks, and 8-weeks. Linear mixed models and negative binomial models compared changes between conditions in ED attitudes, ED behaviors, and weight at each timepoint. Chi-square test and independent samples t-test compared program completion and session engagement between conditions.

RESULTS

No significant differences in weight change or ED symptom change emerged between the conditions. Both conditions achieved significant reductions in ED attitudes, binge episodes, and compensatory behaviors from baseline to 8-weeks (ps < .05). Neither condition demonstrated significant weight loss from baseline to 8-weeks. Program completion (47 %) and session engagement (57 %) were equally high across conditions.

DISCUSSION

Both conditions achieved ED symptom change; however, neither condition was associated with weight change. Research is needed to identify the types of strategies and doses of BWL that promote clinically significant weight and ED symptom change in young adults.

Management of eating disorders for people with higher weight: clinical practice guideline

INTRODUCTION

The prevalence of eating disorders is high in people with higher weight. However, despite this, eating disorders experienced by people with higher weight have been consistently under-recognised and under-treated, and there is little to guide clinicians in the management of eating disorders in this population.

AIM

The aim of this guideline is to synthesise the current best practice approaches to the management of eating disorders in people with higher weight and make evidence-based clinical practice recommendations.

METHODS

The National Eating Disorders Collaboration Steering Committee auspiced a Development Group for a Clinical Practice Guideline for the treatment of eating disorders for people with higher weight. The Development Group followed the 'Guidelines for Guidelines' process outlined by the National Health and Medical Research Council and aim to meet their Standards to be: 1. relevant and useful for decision making; 2. transparent; 3. overseen by a guideline development group; 4. identifying and managing conflicts of interest; 5. focused on health and related outcomes; 6. evidence informed; 7. making actionable recommendations; 8. up-to-date; and, 9. accessible. The development group included people with clinical and/or academic expertise and/or lived experience. The guideline has undergone extensive peer review and consultation over an 18-month period involving reviews by key stakeholders, including experts and organisations with clinical academic and/or lived experience.

RECOMMENDATIONS

Twenty-one clinical recommendations are made and graded according to the National Health and Medical Research Council evidence levels. Strong recommendations were supported for psychological treatment as a first-line treatment approach adults (with bulimia nervosa or binge-eating disorder), adolescents and children. Clinical considerations such as weight stigma, interprofessional collaborative practice and cultural considerations are also discussed.

CONCLUSIONS

This guideline will fill an important gap in the need to better understand and care for people experiencing eating disorders who also have higher weight. This guideline acknowledges deficits in knowledge and consequently the reliance on consensus and lower levels of evidence for many recommendations, and the need for research particularly evaluating weight-neutral and other more recent approaches in this field.

Physical and mental health outcomes of an integrated cognitive behavioural and weight management therapy for people with an eating disorder characterized by binge eating and a high body mass index: a randomized controlled trial

BACKGROUND

Bulimia nervosa (BN) and binge eating disorder (BED) are eating disorders (EDs) characterized by recurrent binge eating. They are associated with medical complications, impaired adaptive function and often a high BMI, for which a multidisciplinary treatment approach may be needed. This study explored the efficacy of a novel intervention integrating Cognitive Behavioural Therapy- Enhanced (CBT-E) and weight management for people with recurrent binge eating episodes and high BMI with respect to physical, psychopathological and quality of life outcomes.

METHODS

Ninety-eight adults diagnosed with BN, BED, or Other Specified/Unspecified Feeding or Eating Disorder (OSFED/UFED) and BMI ≥ 27 to <40 kg/m² were randomized to a multidisciplinary approach, the Healthy APproach to weIght management and Food in Eating Disorders (HAPIFED) or to CBT-E. Metabolic parameters, health-related quality of life, general psychological and ED symptoms and ED diagnostic status outcomes are reported. Data were analyzed with mixed effects models adopting multiple imputed datasets where data were missing.

RESULTS

Both HAPIFED and CBT-E showed statistical significance for the time effect, with reduction in stress (p < 0.001), improvement in mental health-related quality of life (p = 0.032), reduction in binge eating severity (p < 0.001), and also in global ED symptoms scores (p < 0.001), with the significant changes found at end of treatment and sustained at 12-month follow-up. However, no statistical significance was found for differences between the interventions in any of the outcomes measured. Despite a high BMI, most participants (> 75%) had blood test results for glucose, insulin, triglycerides and cholesterol within the normal range, and 52% were within the normal range for the physical component of quality of life at baseline with no change during the trial period.

CONCLUSION

Integrating weight and ED management resulted in comparable outcomes to ED therapy alone. Although adding weight management to an ED intervention had no adverse effects on psychological outcomes, it also had no beneficial effect on metabolic outcomes. Therefore, more intense weight management strategies may be required where indicated to improve metabolic outcomes. Safety will need to be concurrently investigated.

TRIAL REGISTRATION

US National Institutes of Health clinical trial registration number NCT02464345 , date of registration 08/06/2015. Changes to the present paper from the published protocol paper (Trials 18:578, 2015) and as reported in the Trial registration (clinicaltrials.gov) are reported in Supplementary File 1.

Binge eating disorder

Binge eating disorder (BED) is characterized by regular binge eating episodes during which individuals ingest comparably large amounts of food and experience loss of control over their eating behaviour. The worldwide prevalence of BED for the years 2018-2020 is estimated to be 0.6-1.8% in adult women and 0.3-0.7% in adult men. BED is commonly associated with obesity and with somatic and mental health comorbidities. People with BED experience considerable burden and impairments in quality of life, and, at the same time, BED often goes undetected and untreated. The aetiology of BED is complex, including genetic and environmental factors as well as neuroendocrinological and neurobiological contributions. Neurobiological findings highlight impairments in reward processing, inhibitory control and emotion regulation in people with BED, and these neurobiological domains are targets for emerging treatment approaches. Psychotherapy is the first-line treatment for BED. Recognition and research on BED has increased since its inclusion into DSM-5; however, continuing efforts are needed to understand underlying mechanisms of BED and to improve prevention and treatment outcomes for this disorder. These efforts should also include screening, identification and implementation of evidence-based interventions in routine clinical practice settings such as primary care and mental health outpatient clinics.

Characterizing reasons for exercise in binge-spectrum eating disorders

Although 40-60% of individuals with eating disorders (EDs) report engaging in maladaptive exercise, self-reported reasons for engaging in exercise vary. Further, no studies have examined momentary reasons for exercise and whether reasons for exercising could be both adaptive and maladaptive for any episode. Examining reasons for exercise can inform interventions which more effectively target maladaptive exercise. The current study recruited adults with binge-spectrum EDs (N = 58, 89.2% Female) and assessed self-reported reasons for exercise using ecological momentary assessment over 7-14 days. Exercise episodes were categorized as maladaptive if the participant endorsed exercising to compensate for eating or feeling driven to exercise. On average, participants reported exercising 8 times (SD = 8) over the 7-14 days. On average, 73% of exercise episodes were maladaptive. Participants most frequently stated exercising to control shape or weight (67.2% of episodes), feeling driven (62.9%), and exercising as part of a routine (52.9%). Participants least endorsed exercising so that they could eat more later (9.8%). Participants reported a mean of 3.6 reasons for exercising at each episode (SD = 1.85, mode = 1.0). As hypothesized, individuals with EDs were exercising for several reasons at each exercise episode. Further, the extent to which each exercise episode is maladaptive varied between participants and even within a single participant's exercise episodes. These findings underscore the importance of research evaluating when, and for whom, exercise becomes maladaptive, as well as research examining other characteristic features of maladaptive and adaptive exercise in EDs.

Baseline Predictors of Adherence in a Randomised Controlled Trial of a New Group Psychological Intervention for People with Recurrent Binge Eating Episodes Associated to Overweight or Obesity

Purpose: Understanding the high rate of treatment adherence in trials of people with eating disorders is important as it can compromise the quality of the trials. In clinical practice, it may also contribute to illness chronicity, relapse, and costs. Thus, we investigated factors associated with adherence to a new treatment HAPIFED, which integrates cognitive behavioural therapy having extended sessions with body weight loss therapy compared to cognitive behavioural therapy with extended sessions alone, for individuals with Bulimia Nervosa or Binge Eating Disorder or other eating disorders comorbid with overweight or obesity. Methods: In total, 98 participants having bulimia nervosa, binge eating disorder and other specified and unspecified eating disorders were recruited with 50 randomised to HAPIFED and 48 to the control intervention CBT-E, all administered in groups of up to 10 participants. An investigator external to the site conducted the random allocation, which was concealed from the statistician involved in the analysis, and known only to the therapists until the finalization of the 12-month follow-up after the end of active treatment. Three scenarios in the timeline treatment of a total of 30 sessions were assessed: 33% or 60% or 75% of presence. Mixed-effects logistic regression analysis was performed to find the correlates of adherence after adjusting for clustering by number of group participants. To account for heterogeneity by types of eating disorders in the sample, the latter variable was considered as a control factor in the models. A subgroup analysis was performed for those with binge eating disorder as this was the largest (N = 66) eating disorder group. Results: None of the six variables—frequency of binge eating episodes, purging, eating disorder symptom severity, weight, illness duration and mental health-related quality of life—significantly predicted adherence at 33%, but longer illness duration predicted higher treatment adherence at both 60% and 75% presence of the interventions. Also for 75% presence, higher body weight predicted lower treatment adherence. For the subgroup analysis, those having higher illness duration had significantly higher odds of treatment adherence for 60% and 75% of the sessions. Conclusions: Higher adherence due to late treatment completion was associated with longer binge eating illness length and a lower body weight. More research is needed to recognize factors that may interfere with engagement in treatments aiming to avoid early dropout.

The neurostructural and neurocognitive effects of physical activity: A potential benefit to promote eating disorder recovery

Accumulating evidence suggests that supervised and adapted physical activity provides cognitive benefits for individuals with eating disorders (EDs). The mechanisms underlying the benefits of physical activity are poorly understood. Addressing this knowledge gap may inform the appropriate integration of structured physical activity into eating disorders treatment and recovery. We draw attention to recent findings in the study of the impact of physical activity on the brain, and we describe the neurostructural and neurocognitive changes associated with physical activity observed in various clinical and nonclinical populations. Considering the identified impairment in brain volume- and/or neurocognitive function in various EDs, we propose that positive effects of physical activity may play a meaningful role in successful ED treatment. Accordingly, we outline research steps for closing the knowledge gap on how physical activity may aid in ED recovery, and emphasize the need to combine measures of cognitive and behavioral responses to physical activity, with technology capable of measuring changes in brain structure and/or function.

A Group Intervention for Individuals With Obesity and Comorbid Binge Eating Disorder: Results From a Feasibility Study

PURPOSE

A common challenge among a subgroup of individuals with obesity is binge eating, that exists on a continuum from mild binge eating episodes to severe binge eating disorder (BED). BED is common among bariatric patients and the prevalence of disordered eating and ED in bariatric surgery populations is well known. Conventional treatments and assessment of obesity seldom address the underlying psychological mechanisms of binge eating and subsequent obesity. This study, titled PnP (People need People) is a psychoeducational group pilot intervention for individuals with BED and obesity including patients with previous bariatric surgery. Design, feasibility, and a broad description of the study population is reported.

MATERIAL AND METHODS

A total of 42 patients were from an obesity clinic referred to assessment and treatment with PnP in a psychoeducational group setting (3-hour weekly meetings for 10 weeks). Of these, 6 (14.3%) patients had a previous history of bariatric surgery. Feasibility was assessed by tracking attendance, potentially adverse effects and outcome measures including body mass index (BMI), eating disorder pathology, overvaluation of shape and weight, impairment, self-reported childhood difficulties, alexithymia, internalized shame as well as health related quality of life (HRQoL).

RESULTS

All 42 patients completed the intervention, with no adverse effects and a high attendance rate with a median attendance of 10 sessions, 95% CI (8.9,9.6) and 0% attrition. Extent of psychosocial impairment due to eating disorder pathology, body dissatisfaction and severity of ED symptoms were high among the patients at baseline. Additionally, self-reported childhood difficulties, alexithymia, and internalized shame were high among the patients and indicate a need to address underlying psychological mechanisms in individuals with BED and comorbid obesity. Improvement of HRQoL and reduction of binge eating between baseline and the end of the intervention was observed with a medium effect.

CONCLUSION

This feasibility study supports PnP as a potential group psychoeducational intervention for patients living with BED and comorbid obesity. Assessments of BED and delivery of this intervention may optimize selection of candidates and bariatric outcomes. These preliminary results warrant further investigation via a randomized control trial (RCT) to examine the efficacy and effectiveness of PnP.

The treatment of binge eating disorder with cognitive behavior therapy and other therapies: An overview and clinical considerations

Binge eating disorder (BED) is a public health problem in several countries. BED is commonly associated with comorbidities such as obesity, diabetes, and depression. Notwithstanding the health problems associated with BED, evidence-based treatments for BED are not widely used by healthcare professionals worldwide. Thus, we provide an overview of the leading evidence-based psychological therapies for BED, with the intention of informing healthcare professionals and the general community and facilitating greater provision of treatment. Cognitive behavior therapy (CBT) for BED is briefly presented, focusing mainly on adaptations and stages of the cognitive behavior therapy-enhanced (CBT-E) transdiagnostic model for eating disorders. We also succinctly discuss the use of CBT in combination with weight management interventions or pharmacotherapy, as well as the use of interpersonal therapy and dialectical behavior therapy for BED. We conclude that there is a variety of evidence-based psychological therapies that can be used by a variety of healthcare professionals (not only by psychologists) to help reduce binge eating and associated psychopathology in people with BED. Given the high and increasing prevalence of BED, as well as the availability of effective evidence-based treatments, we encourage more healthcare professionals to explore up-skilling to assist people with BED.
