Lobo I, da Luz FQ, Hay P, Gaeta TL, Teixeira PC, Cordás TA, Sainsbury A, Salis Z. Is binge eating associated with poor weight loss outcomes in people with a high body weight? A systematic review with meta-analyses. Eat Weight Disord 2023; 28:89. [PMID: 37889364 PMCID: PMC10611631 DOI: 10.1007/s40519-023-01613-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Accepted: 10/15/2023] [Indexed: 10/28/2023] Open
Abstract
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.

Abstract
Anxiety disorders are the most common group of mental disorders. There is mounting evidence demonstrating the importance of nutrition in the development and progression of mental disorders such as depression; however, less is known about the role of nutrition in anxiety disorders. This scoping review sought to systematically map the existing literature on anxiety disorders and nutrition in order to identify associations between dietary factors and anxiety symptoms or disorder prevalence as well as identify gaps and opportunities for further research. The review followed established methodological approaches for scoping reviews. Due to the large volume of results, an online program (Abstrackr) with artificial intelligence features was used. Studies reporting an association between a dietary constituent and anxiety symptoms or disorders were counted and presented in figures. A total of 55,914 unique results were identified. After a full-text review, 1541 articles met criteria for inclusion. Analysis revealed an association between less anxiety and more fruits and vegetables, omega-3 fatty acids, “healthy” dietary patterns, caloric restriction, breakfast consumption, ketogenic diet, broad-spectrum micronutrient supplementation, zinc, magnesium and selenium, probiotics, and a range of phytochemicals. Analysis revealed an association between higher levels of anxiety and high-fat diet, inadequate tryptophan and dietary protein, high intake of sugar and refined carbohydrates, and “unhealthy” dietary patterns. Results are limited by a large percentage of animal and observational studies. Only 10% of intervention studies involved participants with anxiety disorders, limiting the applicability of the findings. High quality intervention studies involving participants with anxiety disorders are warranted.

Nocturnal eating but not binge eating disorder is related to less 12 months' weight loss in men and women with severe obesity: A retrospective cohort study. Clin Obes 2020; 10:e12408. [PMID: 32851796 PMCID: PMC7685102 DOI: 10.1111/cob.12408] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/08/2020] [Revised: 07/28/2020] [Accepted: 08/07/2020] [Indexed: 12/24/2022]
Abstract
There is a paucity of studies on the frequency of binge-eating disorder (BED) and nocturnal eating (NE) and their potential role as barriers in non-surgical weight loss treatment in subjects with severe obesity (body mass index [BMI] ≥35 kg m2 ). The aim was to identify BED and NE, and their effect on weight loss treatment. In total, 1132 (727 women, 405 men), BMI ~41 kg/m2 were patients in a 12-month weight loss programme at a specialist clinic. The questionnaire for eating and weight patterns-revised was completed by the patients before start of treatment. BED was diagnosed in 5.1% of men and 12.4% of women. NE prevalence was 13.5% and 12.7%, respectively. Mean (±SEM) 12-month weight loss was less in patients with NE compared to those without (-11.0 ± 1.5 vs -14.6 ± 0.7 kg, P = .008) but did not differ in patients with and without BED, (-12.3 ± 1.9 vs -14.2 ± 0.6 kg, P = .24). Factors associated with dropout were BED (odds ratio, OR 1.57, 95% confidence interval (CI) 1.14-2.17; P = .006) and previous weight loss attempts (OR 1.35, 95% CI 1.0-1.7; P = .02). BED did not seem to hinder weight loss whereas NE resulted in less weight loss in patients with severe obesity who completed a 12-month treatment programme. Previous weight loss attempts affect both dropout and ability to lose weight.

Obes Rev 2015; 16:652-65.

Abstract
Severe dietary energy restriction is often used for overweight or obese individuals to achieve rapid weight loss and related health improvements. However, the extent of putative adverse effects on eating behaviour is unknown. We thus systematically searched seven databases for studies that assessed binge eating before and after severe dietary energy restriction (low or very low energy diets) in overweight or obese individuals. Fifteen clinically supervised interventions from 10 publications (nine of which involved only women) were included. Among individuals with clinically relevant pre-treatment binge eating disorder, severe dietary energy restriction significantly decreased binge eating in all four interventions involving this population, at least during the weight loss programme. In contrast, no consistent association between severe dietary energy restriction and the onset of bingeing was found in 11 interventions involving individuals without pre-treatment binge eating disorder, with four such interventions showing significant increases, two showing no change, and five showing significant decreases in binge eating. We conclude that clinically supervised severe dietary energy restriction appears safe and beneficial for overweight or obese individuals with pre-treatment binge eating disorder, and does not necessarily trigger binge eating in those without binge eating disorder.

Abstract
To determine the effects of binge eating disorder (BED) on weight loss and maintenance in women undergoing treatment for obesity, we studied the weight changes of 38 women (body mass index > 30 kg/m2), 21 of whom met proposed criteria for BED and 17 of whom reported few problems with binge eating, during and after a 26-week comprehensive very-low-calorie diet (VLCD) treatment program. All 17 subjects without and 16/21 subjects with BED returned for four follow-up visits over 12 months (p = 0.05). While a similar proportion of subjects with and without BED reported absolute adherence to both the modified fast and refeeding, those with BED showed a significantly different distribution in energy intake from those without BED, with fewer small and more large lapses among those who deviated from the diet (p < 0.05). There was no significant difference in mean weight loss over the 26 weeks of treatment, but subjects with BED showed significantly diminished weight loss during the middle third of treatment (p < 0.05). Black subjects, regardless of the presence of BED, lost significantly less weight during treatment than white subjects (p < 0.005). Although there was no significant difference in mean weight loss at any of the four follow-up visits between subjects with and without BED, 25% of subjects with BED had regained > 50% of their lost weight by three-month follow-up, vs. no subjects without the disorder (p < 0.05). One year after completing treatment, approximately half of BED (+) and BED (-) subjects had a good outcome, maintaining a weight loss > or = 10% of initial body weight. However, 35% of subjects with BED, and none of the subjects without BED, had a poor outcome (p < 0.05). We conclude that many individuals with BED will respond well to a medically supervised comprehensive VLCD program, attaining medically significant weight loss. However, this subgroup appears to be at risk for early major regain of lost weight and for poor outcome one year following weight-loss treatment.

Abstract
Binge eating disorder (BED) is a newly characterized eating disorder that encompasses individuals who have severe distress and dysfunction due to binge eating, but who do not regularly engage in inappropriate compensatory behaviors. While relatively uncommon in the general community, BED becomes more prevalent with increasing severity of obesity. BED is associated with early onset of obesity, frequent weight cycling, body shape disparagement, and psychiatric disorders. These associations occur independent of the degree of obesity. Although many individuals with BED have good short-term weight loss regardless of treatment modality, as a group they may be prone to greater attrition during weight-loss treatment and more rapid regain of lost weight. Current treatments geared toward binge eating behaviors include antidepressant medications, cognitive behavioral psychotherapy, and interpersonal psychotherapy; however, these treatments have little efficacy in promoting weight loss, and only modest success in long-term reduction of binge eating. As a significant proportion of obese individuals entering weight-loss treatment and research programs are likely to meet criteria for BED, those conducting clinical research should be aware of this distinct subgroup and determine the contribution of BED to outcome measures.

Abstract
Attendance and completion of weight loss intervention is associated with better weight loss outcomes; however, attrition is neither consistently reported nor comprehensively explored in the weight loss literature. A systematic review was undertaken to identify factors associated with attrition in weight loss interventions involving overweight or obese (body mass index ≥ 25) adults (18-65 years). Sixty-one studies published before May 2011 and addressing factors associated with weight loss programme attrition were identified. Conclusions were limited by the large number of variables explored, the small number of studies exploring each variable, the large variety of study settings and methodologies used, the inconsistent reporting of results, and the conflicting findings across studies. A consistent set of predictors has not yet been identified. The majority of studies relied on pre-treatment routinely collected data rather than variables selected because of their theoretical and/or empirical relationship with attrition. However, psychological and behavioural patient factors and processes associated with the treatment were more commonly associated with attrition than patient background characteristics. Future research should consider theoretically grounded social-psychological and behavioural processes as potential predictors of dropout. Identification of patients at risk of dropout will contribute to both the effectiveness and the cost-effectiveness of weight loss interventions.

Abstract
The most prevalent disordered eating pattern described in overweight youth is loss of control (LOC) eating, during which individuals experience an inability to control the type or amount of food they consume. LOC eating is associated cross-sectionally with greater adiposity in children and adolescents and seems to predispose youth to gain weight or body fat above that expected during normal growth, thus likely contributing to obesity in susceptible individuals. No prior studies have examined whether LOC eating can be decreased by interventions in children or adolescents without full-syndrome eating disorders or whether programs reducing LOC eating prevent inappropriate weight gain attributable to LOC eating. Interpersonal psychotherapy, a form of therapy that was designed to treat depression and has been adapted for the treatment of eating disorders, has shown efficacy in reducing binge eating episodes and inducing weight stabilization among adults diagnosed with binge eating disorder. In this paper, we propose a theoretical model of excessive weight gain in adolescents at high risk for adult obesity who engage in LOC eating and associated overeating patterns. A rationale is provided for interpersonal psychotherapy as an intervention to slow the trajectory of weight gain in at-risk youth, with the aim of preventing or ameliorating obesity in adulthood.

Abstract
Prompted by the large heterogeneity of individual results in obesity treatment, many studies have attempted to predict weight outcomes from information collected from participants before they start the programme. Identifying significant predictors of weight loss outcomes is central to improving treatments for obesity, as it could help professionals focus efforts on those most likely to benefit, suggest supplementary or alternative treatments for those less likely to succeed, and help in matching individuals to different treatments. To date, however, research efforts have resulted in weak predictive models with limited practical usefulness. The two primary goals of this article are to review the best individual-level psychosocial pre-treatment predictors of short- and long-term (1 year or more) weight loss and to identify research needs and propose directions for further work in this area. Results from original studies published since 1995 show that few previous weight loss attempts and an autonomous, self-motivated cognitive style are the best prospective predictors of successful weight management. In the more obese samples, higher initial body mass index (BMI) may also be correlated with larger absolute weight losses. Several variables, including binge eating, eating disinhibition and restraint, and depression/mood clearly do not predict treatment outcomes, when assessed before treatment. Importantly, for a considerable number of psychosocial constructs (e.g. eating self-efficacy, body image, self-esteem, outcome expectancies, weight-specific quality of life and several variables related to exercise), evidence is suggestive but inconsistent or too scant for an informed conclusion to be drawn. Results are discussed in the context of past and present conceptual and methodological limitations, and several future research directions are described.

Abstract
OBJECTIVE To investigate the characteristics and prevalence of binge eating among overweight Taiwanese and to determine the effect of binge eating on outcome of weight loss treatment. METHODS One hundred and eighty-nine participants in a 12-week traditional weight-reduction program were classified on the basis of the Bulimic Investigation Test, Edinburgh (BITE) scores into binge eaters (>/=20), subthreshold binge eaters (10-19), and nonbinge eaters (0-9). RESULTS This study found a 15.9% prevalence of binge eating. The binge-eating groups (binge eaters and subthreshold binge eaters) were younger, had an earlier onset of obesity, and more psychological distress than nonbinge eaters. Differences in obesity treatment weight loss among binge eaters, subthreshold binge eaters, or nonbingers by last observation carried forward (LOCF) method were not significant. At the end of treatment, the subthreshold binge eaters had the greatest weight loss. Although their binge eating and mood significantly improved, binge eaters and subthreshold binge eaters still had significant pathology in eating behaviors at completion of the program. CONCLUSION Alternative treatment strategies focusing on disordered eating behaviors are needed to supplement standard dietary management of overweight treatment-seeking binge eaters.

Abstract
OBJECTIVE To describe the evidence for the constellation of symptoms known as binge eating disorder (BED) and to evaluate the utility of this diagnosis. METHODS Examination of the definition, prevalence, psychiatric comorbidity, and treatment of BED through a selective review of the literature. RESULTS The objective definition of a binge (its size and duration) remains problematic. Persons with BED have extensive comorbid psychopathology. Pharmacologic treatments effectively reduce binge eating, but only somewhat more than placebos, whereas psychotherapeutic treatments reduce binge eating, but do not produce weight loss. Traditional behavioral weight loss programs produce both weight loss and decreases in binge eating. The course of BED is variable and often remits with nonspecific attention or during wait-list conditions. CONCLUSIONS Although there is consensus on the criteria for BED, its great variability limits the implications that can be drawn from its diagnosis, and it may be most useful as a marker of psychopathology.

Abstract
OBJECTIVE The authors review the available literature on psychological and dietary treatment approaches for binge eating disorder (BED). METHODS Studies were grouped according to psychological versus dietary approaches to BED. Studies were reviewed in terms of general implications, but particular emphasis was placed on drop-out rates, abstinence from binge eating, and weight loss. RESULTS Drop-out rates from psychological or dietary approaches to treatment averaged 20% and the presence of binge eating did not confer a greater risk of drop-out among obese individuals. Both psychological and dietary approaches to treatment produced abstinence rates from binge eating of approximately 50% at the 12-month follow-up. Both psychological and dietary approaches show modest efficacy of short-term weight loss, but these effects are generally not sustained in long-term follow-up assessments. DISCUSSION Psychological and dietary approaches to BED treatment show reasonable efficacy in binge eating reduction, but limited efficacy in weight loss. These findings are discussed in terms of the validity of the BED construct and the need for more psychopathology studies of BED.

Abstract
OBJECTIVE Binge eating disorder (BED) and the night eating syndrome (NES) have been linked to obesity. This review summarizes their characteristics, implications of their diagnoses and treatment outcomes. METHOD Selective review of the literature on BED and NES. RESULTS BED was proposed as a distinctive disorder on the basis of two large multisite studies in the early 1990s. It is associated with more severe and earlier onset of obesity, earlier onset of dieting and greater psychopathology. It shows large placebo responses and reduction of bingeing in patients on waiting-list controls. Traditional weight reduction programs reduce bingeing at least as well as psychological treatments designed for this purpose. NES is a stress-related eating, sleeping and mood disorder that is associated with disordered neuroendocrine function. It follows a characteristic circadian pattern and has responded to an agent that enhances serotonin function. CONCLUSIONS BED responds well to weight reduction programs. It is proposed that this diagnosis be used as a marker for psychological problems that deserve treatment in their own right. NES is an eating, sleep, and mood disorder with distinctive behavioral and neuroendocrine characteristics. Studies of treatment for NES are in their infancy but selective serotonin reuptake inhibitors (SSRI) show promise.

Abstract
OBJECTIVE To determine psychological and behavioral correlates of baseline BMI in the Diabetes Prevention Program (DPP). RESEARCH DESIGN AND METHODS Of 1,079 DPP lifestyle intervention participants, 274 completed validated questionnaires at baseline assessing weight loss history, stage of change, self-efficacy, dietary restraint, emotional eating, binge eating, perceived stress, depression, and anxiety. RESULTS The mean age of subjects was 52.5 years, 65% were women, and their mean BMI was 33.9 kg/m(2). Higher BMI correlated with more frequent weight cycling (r = 0.50, P < 0.0001) and efforts at weight loss (r = 0.34, P < 0.0001); younger age when first overweight (r = -0.42, P < 0.0001); lower exercise efficacy (r = -0.15, P = 0.015); lower weight loss efficacy (r = -0.21, P < 0.001); a less advanced stage of change for weight loss (r = -0.12, P = 0.04); more perceived stress (r = 0.14, P = 0.02); emotional eating (r = 0.19, P = 0.001); poor dietary restraint (r = -0.14, P = 0.02); binge eating frequency (r = 0.18, P = 0.004) and severity (r = 0.30, P < 0.0001); feeling deprived, angry, or upset while dieting (r = 0.27, P </= 0.0001); and food cravings while dieting (r = 0.31, P < 0.0001). Correlations did not differ as a function of sex; however, correlations of BMI with anxiety and low-fat diet and weight loss self-efficacy differed as a function of ethnicity. In multivariate models, binge eating severity, poor dietary restraint, and food craving were independent correlates of baseline BMI. CONCLUSIONS Many psychological and behavioral factors are associated with higher BMI in this ethnically diverse group of men and women. Whether strategies that help patients increase levels of dietary restraint and reduce binge eating and food craving lead to long-term weight loss maintenance needs longitudinal study.

Abstract
Very low energy diets (VLEDs) are defined as diets which contain energy levels of less than 3.4 MJ (800 kcal) per day and contain daily allowances of all essential nutritional requirements. These diets have been in clinical use for more than 20 years. They are used as the only source of nutrition for 8-16 weeks, which usually achieves a weight loss of 1.5-2.5 kg per week. Before using this type of diet a medical investigation is necessary to evaluate contraindications and to check medication use during the diet. To facilitate maintenance, cognitive behavioural counselling should always be included in a weight reduction programme using a very low energy diet. VLEDs have no serious harmful effects and can safely be used in patients with various chronic diseases. Programmes using VLEDs produce better short-term weight loss than programmes without the diet. However, in randomized controlled trials VLED-based programmes have not achieved significantly better long-term maintenance than conventional programmes. VLEDs are used when rapid weight loss is necessary because of an obesity-related disease. In other patients with obesity it is an alternative to other conservative approaches for treatment of obesity. In type 2 diabetes it may improve long-term glucose metabolism better than conventional weight reducing diets. Some studies suggest that after a VLED-based programme long-term maintenance is better among men than women. This possible gender difference is an important topic for further research.

Abstract
Dimensions of body image in a sample of obese women diagnosed with binge eating disorder (BED; N=42) were compared with a sample of obese women without BED (non-BED; N=42), matched on age and BMI. Additionally, the relationship between BED, body image and several dimensions of treatment response was examined. Results indicated BED women were more likely to negatively evaluate their global physical appearance and have less satisfaction with specific areas of the body than were non-BED women, even after controlling for depression scores. While BED women were significantly more likely to endorse depressive symptoms, depression scores were negatively correlated with body satisfaction in non-BED women only. BED women did not fare worse in formal weight-loss treatment, as measured by length of time in treatment, group-therapy attendance, or BMI at posttreatment. The role of body image in women with BED seeking weight-loss treatment is discussed relevant to the context of potential impact of BED and negative body image on active weight-loss treatment and maintenance.

Abstract
Dieting has been implicated as a potential contributor in the development of binge eating problems in binge eating disorder (BED). If dieting plays a causal role in the etiology of BED, this could have major implications for understanding and treating individuals with the disorder. This article reviews the existing literature on the role of dieting in BED. Retrospective studies of dieting history, research on levels of dietary restraint, and prospective studies investigating the effects of dieting on subsequent eating behavior are explored. Although the literature is inconclusive as to the exact role that dieting plays in the etiology of BED, recommendations for future research and suggestions for treatment are given.

Abstract
This study investigated the relationship between binge eating and the outcome of weight loss treatment. Participants in a 48-week trial of a structured diet combined with exercise and behavior therapy were classified into one of four groups: no overeating; episodic overeating; subthreshold binge-eating disorder(BED); and BED. Binge eating status was not associated with either dropout or adherence to the diet, but did affect weight loss and mood. The BED group lost significantly more weight at the end of treatment than all other groups, even when adjusting for initial weight. At 1-year follow-up, there were no differences among groups in weight loss or weight regain. The BED group began treatment with significantly higher BDI scores, but improvement in mood occurred by week 5. On the basis of these findings, and a review of the recent literature, we conclude that obese binge eaters respond as favorably to standard dietary and behavioral treatments as do obese nonbingers.

Abstract
Obese individuals with binge eating disorder (BED) differ from obese non-binge eating (NBE) individuals in a number of clinically relevant ways. This study examined attitudinal responses to various measures of body image in women seeking obesity treatment, by comparing NBE participants (n = 80) to those with BED (n = 48). It was hypothesized that women with BED would demonstrate greater attitudinal disturbance of body image compared to NBE individuals. It was further hypothesized that significant differences between groups would remain after statistically controlling for degree of depression. Consistent with the primary hypothesis, BED participants reported significantly increased attitudinal disturbance in body dissatisfaction and size perception compared to NBE participants. Although shared variance was observed between measures of depression and body image on some items, several aspects of increased body image disturbance remained after statistically controlling for depression. Treatment implications and recommendations for future research are discussed.

Abstract
Consistent predictors of attrition in obesity treatment have not been identified. This study examined whether pretreatment psychological and health behavior variables would predict attrition from a 26 week clinical multidisciplinary VLCD and behavior therapy program. Higher levels of depression, current smoking, being sedentary, and having nontreated high blood pressure were associated with treatment attrition. Thus, a biopsychosocial assessment which evaluates medical and psychiatric status may help clinicians to identify individuals at high risk for attrition.

Abstract
There is controversy over how best to classify eating disorders in which there is recurrent binge eating. Many patients with recurrent binge eating do not meet diagnostic criteria for other of the two established eating disorders, anorexia nervosa or bulimia nervosa. The present study was designed to derive an empirically based, and clinically meaningful, diagnostic scheme by identifying subgroups from among those with recurrent binge eating, testing the validity of these subgroups and comparing their predictive validity with that of the DSM-IV scheme. A general population sample of 250 young women with recurrent binge eating was recruited using a two-stage design. Four subgroups among the sample were identified using a Ward's cluster analysis. The first subgroup had either objective or subjective bulimic episodes and vomiting or laxative misuse; the second had objective bulimic episodes and low levels of vomiting or laxative misuse; the third had subjective bulimic episodes and low levels of vomiting or laxative misuse; and the fourth was heterogeneous in character. This cluster solution was robust to replication. It had good descriptive and predictive validity and partial construct validity. The results support the concept of bulimia nervosa and its division into purging and non-purging subtypes. They also suggest a possible new binge eating syndrome. Binge eating disorder, listed as an example of Eating Disorder Not Otherwise Specified within DSM-IV, did not emerge from the cluster analysis.

Abstract
Research in obesity has generally not demonstrated an association with increased rates of psychopathology compared to normal-weight comparison groups. However, studies of obese individuals from clinical samples with recurrent binge eating or binge eating disorder (BED) have generally revealed increased rates of psychiatric comorbidity compared to non-binge eating obese individuals. Also, several studies have reported finding an association between BED and elevated rates of psychological distress, social problems, and impaired self-esteem. This report provides an overview of research findings regarding psychiatric comorbidity among individuals with BED, and it presents suggestion for future research.

Abstract
Behavioral therapy for obesity that is, the application of learning theory to obesity treatment is now a standard component of weight-loss programs. The hallmark of behavioral therapy for obesity is self-monitoring of eating behavior, but techniques of stimulus control, self-reward, cognitive restructuring, nutrition education, and physical activity are also emphasized. Although behavioral treatment programs that incorporate lengthier and more intensive regimens are often successful in producing short-term weight loss, most patients have regained much or all of their lost weight at long-term follow-up. One approach to this problem has been to supplement behavioral treatment with other modalities such as very-low-calorie diets, surgical procedures, and medication. Whatever the initial treatment, obesity clearly must be approached as a chronic disorder that necessitates long-term intervention, and relapse prevention and weight maintenance strategies are crucial for long-term success. Another important development in behavioral treatment of obesity has been the attempt to identify subgroups of obese persons, such as those with uncontrolled binge eating, who might benefit from specific management approaches. Treatment programs for binge eating are strongly influenced by techniques developed for other types of eating disorders such as bulimia. Although use of only behavioral therapy is insufficient, it has an important adjunctive role for many patients particularly as we improve our abilities to tailor treatment to the individual subject and to promote long-term weight maintenance.

Abstract
A representative sample from a nonclinical population was drawn to compare bingers and nonbingers across weight categories. Subjects were 112 women drawn from a cross-section of undergraduate classes at a large state university. Four groups were formed: obese bingers, obese nonbingers, normal-weight bingers (bulimics), and normal-weight nonbingers. Bingers, regardless of weight category, suffered higher levels of depression and anxiety and lower levels of self-esteem than nonbingers, regardless of weight category. Obese nonbingers were indistinguishable on these variables from normal-weight nonbingers, with both groups of nonbingers experiencing less emotional distress. Results support the position that the obese population should be conceptualized and treated as a diverse group with different psychological characteristics and needs.
