Weight Loss Expectations in Obese Patients Seeking Treatment at Medical Centers

Objective: To investigate weight loss expectations (expected 1‐year BMI loss, dream BMI, and maximum acceptable BMI) in obese patients seeking treatment and to examine whether expectations differ by sex, weight, diet and weight history, age, psychological factors, and primary motivations for weight loss. Research Methods and Procedures: 1891 obese patients seeking treatment in 25 Italian medical centers (1473 women; age, 44.7 ± 11.0 years; BMI, 38.2 ± 6.5 kg/m²) were evaluated. Diet and weight history, weight loss expectations, and primary motivation for seeking treatment (health or improving appearance) were systematically recorded. Psychiatric distress, binge eating, and body image dissatisfaction were tested by self‐administered questionnaires (Symptom CheckList‐90, Binge Eating Scale, and Body Uneasiness Test). Results: In 1011 cases (53.4%), 1‐year expected BMI loss was ≥9 kg/m², dream BMI was 26.0 ± 3.4 kg/m² (corresponding to a 32% loss), and maximum acceptable BMI was 29.3 ± 4.4 kg/m² (?23%). BMI and age were the strongest predictors of weight goals. Weight loss necessary to reach the desired targets was largely in excess of weight loss observed during previous dieting. Psychiatric distress, body dissatisfaction, and binge eating did not predict weight loss expectations. The primary motivation for weight loss was concern for future or present health; women seeking treatment to improve appearance had a lower grade of obesity, were younger, and had first attempted weight loss at a younger age. Discussion: Obese Italian patients had unrealistic weight loss expectations. There were significant disparities between patients’ perceptions and physicians’ weight loss recommendations of desirable treatment outcome.     

Loss of control is central to psychological disturbance associated with binge eating disorder

Objective: Binge eating disorder (BED) is positively associated with obesity and psychological distress, yet the behavioral features of BED that drive these associations are largely unexplored. The primary aim of this study was to investigate which core behavioral features of binge eating are most strongly related to psychological disturbance. Methods and Procedures: A cross‐sectional study involved 180 bariatric surgery candidates, 93 members of a non‐surgical weight loss support group, and 158 general community respondents (81 men/350 women, mean age 45.8 ± 13.3, mean BMI 34.8 ± 10.8, BMI range 17.7–66.7). Validated questionnaires assessed BED and binge eating, symptoms of depression, appearance dissatisfaction (AD), quality of life (QoL) and eating‐related behaviors. Features of binge eating were confirmed by interview. BMI was determined by clinical assessment and self‐report. Results: The loss of control (LOC) over eating, that is, being unable to stop eating or control what or how much was consumed was most closely related to psychological markers of distress common in BED. In particular, those who experienced severe emotional disturbance due to feelings of LOC reported higher symptoms of depression (P < 0.001), AD (P = 0.009), and poorer mental health–related QoL (P = 0.027). Discussion: Persons who report subjective binge episodes or do not meet BED frequency criteria for objective binge episodes may still be at elevated risk of psychological disturbance and benefit from clinical intervention. Feelings of LOC could drive binge eaters to seek bariatric surgery in an attempt to gain control over body weight and psychologically disturbing eating behavior.     

Patient characteristics as predictors of weight loss after an obesity treatment for children

Objective: To examine pretreatment patient characteristics as predictors of treatment outcome 2 years after completion of an inpatient treatment for children with obesity. Research Methods and Procedures: Children (N = 122) ranging in age from 7 to 17 years [mean, 12.7 ± 2.3 (SD) years] with a mean adjusted BMI of 179.5 ± 28.6% participated in an inpatient obesity treatment program. Children (90.2% response rate) participated in the 2‐year follow‐up. Eight predictors, administered at baseline, were entered in separate regression analyses, with weight loss and changes on three psychological health measures as the outcome measures. Results: Analyses revealed that baseline degree of overweight, age, and initial weight loss were significant positive predictors of weight loss 2 years after treatment, whereas eating disorder characteristics were a negative predictor. Sex, socioeconomic status, global self‐esteem, and symptoms of psychopathology did not predict weight loss. With regard to the psychological outcome measures, baseline symptomatology emerged as the most important predictor of treatment changes. Discussion: Long‐lasting weight loss is associated with severity of pretreatment characteristics. Identification of the clinical markers for long‐term response to treatment is useful to set realistic weight loss goals for clients and to tailor treatment programs to patient characteristics.     

Weight Loss Expectations in Obese Patients and Treatment Attrition: An Observational Multicenter Study

Objective: To investigate the influence of weight loss expectations (expected 1‐year BMI loss, dream and maximum acceptable BMI) on attrition in obese patients seeking treatment. Research Methods and Procedures: Obese subjects (1785; 1393 women; median age, 46 years; median BMI, 36.7 kg/m²) seeking treatment in 23 medical Italian centers were evaluated. Baseline diet and weight history, weight loss expectations, and primary motivation for seeking treatment (health or improving appearance) were systematically recorded. Psychiatric distress, binge eating, and body image dissatisfaction were tested at baseline by self‐administered questionnaires (Symptom Check List‐90, Binge Eating Scale, and Body Uneasiness Test). Attrition and BMI change at 12 months were prospectively recorded. Results: At 12 months, 923 of 1785 patients (51.7%) had discontinued treatment. Compared with continuers, drop‐outs had a significantly lower age, a lower age at first dieting, lower dream BMI, a higher expected 1‐year BMI loss, and a higher weight phobia. At logistic regression analysis, the strongest predictors of attrition at 12 months were lower age and higher expected 1‐year BMI loss. The risk of drop‐out increased systematically for unit increase in expected BMI loss at 12 months (hazard ratio, 1.12; 95% confidence interval, 1.04 to 1.20; p = 0.0018). The risk was particularly elevated in the first 6 months. Discussion: Baseline weight loss expectations are independent cognitive predictors of attrition in obese patients entering a weight‐losing program; the higher the expectations, the higher attrition at 12 months. Unrealistic weight goals should be tackled at the very beginning of treatment.     

Effect of Orlistat in Obese Patients with Binge Eating Disorder

Objective: Binge eating disorder represents a significant public health problem, with up to 50% of weight loss program participants displaying this disorder. In previous studies with orlistat, patients with binge eating disorder were excluded. The goal of this study was to assess the efficacy of orlistat in obese patients with binge eating disorder. Research Methods and Procedures: Eighty‐nine patients with clinically diagnosed binge eating disorder and a BMI ≥ 30 kg/m² were randomized in double‐blind fashion to 24 weeks of treatment with 120 mg of orlistat or placebo three times daily, in combination with a mildly reduced‐calorie diet. Results: After 24 weeks, the mean weight loss from baseline for orlistat‐treated patients was significantly greater than for patients receiving placebo (?7.4% vs. ?2.3%; p = 0.0001) (intent‐to‐treat analysis). The overall Eating Disorder Inventory 2 score at week 24 was significantly lower in patients treated with orlistat than in those in the placebo group (p = 0.011) Discussion: Orlistat may be considered as part of the management for patients with obesity and binge eating disorder.     

Gastric Bypass in a Low‐Income,Inner‐City Population: Eating Disturbances and Weight Loss

Objective: To examine the prevalence of eating disturbances and psychiatric disorders among extremely obese patients before and after gastric bypass surgery and to examine the relationship between these disturbances and weight outcomes. Research Methods and Procedures: Sixty‐five women patients (ages 19 to 67) with a mean BMI of 54.1 were assessed by semistructured psychiatric interview before surgery and by telephone interview after surgery (mean follow‐up: 16.4 months) to determine psychiatric status, eating disturbances, and weight and health‐related variables. Results: Patients lost a mean of 71% of their excess BMI, with significantly poorer weight loss outcomes among African Americans. Psychiatric disorders remained prevalent before (37%) and after (41%) surgery. In contrast, binge eating disorder dropped from 48% to 0%. Psychiatric diagnosis did not affect weight outcomes. Instead, more frequent preoperative binge eating, along with greater initial BMI, follow‐up length, and postoperative exercise, predicted greater BMI loss. Postsurgical health behaviors (exercise and smoking) and nocturnal eating episodes were also linked to weight loss. Exercise frequency increased and smoking frequency tended to decrease after surgery. Discussion: These findings indicated that eating and psychiatric disturbances did not inhibit weight loss after gastric bypass and should not contraindicate surgery. Prior binge eating, eliminated after surgery, predicted BMI loss and, thus, may have previously been a maintaining factor in the obesity of these patients. The association between health behaviors and outcome suggests possible targets for intervention to improve surgical results. Poorer outcomes among African Americans indicate that these patients should be closely monitored and supported after surgery.     

Appearance vs. Health Reasons for Seeking Treatment Among Obese Patients with Binge Eating Disorder

Objectives : This study examined reasons for seeking treatment reported by obese patients diagnosed with binge eating disorder (BED). Research Methods and Procedures : Participants were 248 adults (58 men and 190 women) who met DSM criteria for BED. Participants were recruited through advertisements for treatment studies looking for persons who wanted to “stop binge eating and lose weight.” Patients’ reasons for seeking treatment were examined with respect to demography (gender and age), obesity (BMI and age of onset), features of eating disorders, and associated psychological functioning (depression and self‐esteem). Results : Of the 248 participants, 64% reported health concerns and 36% reported appearance concerns as their primary reason for seeking treatment. Reasons for seeking treatment did not differ significantly by gender. Patients seeking treatment because of appearance‐related reasons had lower BMIs than those reporting health‐related reasons (34.8 vs. 38.5, respectively), but they reported greater body dissatisfaction, more features of eating disorders, and lower self‐esteem. Discussion : Reasons that prompt treatment seeking among obese individuals with BED reflect meaningful patient characteristics and, therefore, warrant assessment and consideration during treatment planning. Further research is needed to determine whether reasons for treatment seeking among different obese patient groups affect treatment outcomes.     

Sibutramine Treatment in Obesity: Predictors of Weight Loss Including Rorschach Personality Data

Objective: To study personality and clinical factors in weight loss by sibutramine (Meridia and Reductil), an anti‐obesity drug enhancing satiety. Research Methods and Procedures: The subjects were 30 obese patients [43 ± 12 years (mean ± SD), BMI 40 ± 4 kg/m²]. The treatment comprised 15 mg of sibutramine administered daily and monthly dietary advice. Weight loss after 6 months of treatment was evaluated. For psychological assessment, the Rorschach method (Comprehensive System) and the Beck Depression Inventory were used. Results: A multiple linear regression model including the Rorschach predictors’ physical demand states (animal movement, designated as FM) being intrusive or difficult to hold and a dependency orientation (food contents) could explain 47% of 6 months of weight loss. A model including initial weight loss in addition to the Rorschach predictors explained 58% of the 6‐month weight loss. Discussion: The personality factors predicted greater weight loss. In particular, patients with difficulties concerning physical demand states, which would include hunger, could have reduced their eating behavior with enhanced satiety, resulting in greater weight loss. Enhanced satiety could also have helped patients with a dependent need for food to limit food intake. Being enrolled in a treatment program could also have provided essential support for patients with dependency needs. Furthermore, initial weight loss was a predictor of greater weight loss in sibutramine treatment, in accordance with prior research.     

Teasing History,Onset of Obesity,Current Eating Disorder Psychopathology,Body Dissatisfaction,and Psychological Functioning in Binge Eating Disorder

Objective: The primary goal of this study was to examine associations among teasing history, onset of obesity, current eating disorder psychopathology, body dissatisfaction, and psychological functioning in women with Binge Eating Disorder (BED). Research Methods and Procedures: Subjects were 115 female adults who met DSM‐IV criteria for BED. Measurements assessing teasing history (general appearance [GAT] and weight and size [WST] teasing), current eating disorder psychopathology (binge frequency, eating restraint, and concerns regarding eating, shape, and weight), body dissatisfaction, and psychological functioning (depression and self‐esteem) were obtained. Results: History of GAT, but not WST, was associated with current weight concerns and body dissatisfaction, whereas both GAT and WST were significantly associated with current psychological functioning. Patients with earlier onset of obesity reported more WST than patients with later onset of obesity, but the groups did not differ significantly in GAT, current eating disorder psychopathology, body dissatisfaction, or psychological functioning. Obese women reported more WST than non‐obese women, but no differences in GAT or the other outcome variables were observed. Higher frequency of GAT was associated with greater binge frequency in obese women, and with greater eating restraint in non‐obese women. Discussion: Although physical appearance teasing history is not associated with variability in most eating disorder psychopathology, it is associated with related functioning, most notably body dissatisfaction, depression, and self‐esteem. Our findings also suggest that the age of onset of obesity and current body mass index status in isolation are not associated with eating psychopathology or associated psychological functioning in adult patients with BED.     

Cognitive Behavioral Therapy and Fluoxetine as Adjuncts to Group Behavioral Therapy for Binge Eating Disorder

Objective: Although binge eating disorder is a common and distressing concomitant of obesity, it has not yet been established whether affected individuals presenting to behavioral weight control programs should receive specialized treatments to supplement standard treatment. This study was designed to examine the added benefit of two adjunctive interventions, individual cognitive behavioral therapy (CBT) and fluoxetine, offered in the context of group behavioral weight control treatment. Research Methods and Procedures: One hundred sixteen overweight/obese women and men with binge eating disorder were all assigned to receive a 16‐session group behavioral weight control treatment over 20 weeks. Simultaneously, subjects were randomly assigned to receive CBT + fluoxetine, CBT + placebo, fluoxetine, or placebo in a two‐by‐two factorial design. Outcome measures, assessed at the end of the 16‐session acute treatment phase, included binge frequency, weight, and measures of eating‐related and general psychopathology. Results: Overall, subjects showed substantial improvement in binge eating and both general and eating‐related psychopathology, but little weight loss. Subjects who received individual CBT improved more in binge frequency than did those not receiving CBT (p < 0.001), and binge abstinence was significantly more common in subjects receiving CBT vs. those who did not (62% vs. 33%, p < 0.001). Fluoxetine treatment was associated with greater reduction in depressive symptoms (p < 0.05). The 54 subjects who achieved binge abstinence improved more on all measures than the 62 subjects who did not. In particular, these subjects lost, on average, 6.2 kg compared with a gain of 0.7 kg among non‐abstainers. Discussion: Adjunctive individual CBT results in significant additional binge reduction in obese binge eaters receiving standard behavioral weight control treatment.     

A Pilot Randomized Controlled Trial of a Clinic and Home‐Based Behavioral Intervention to Decrease Obesity in Preschoolers

We evaluated the efficacy of a 6‐month clinic and home‐based behavioral intervention (Learning about Activity and Understanding Nutrition for Child Health; LAUNCH) to reduce obesity in preschool children ≥95th BMI percentile compared to enhanced standard of care (Pediatrician Counseling; PC). LAUNCH was a family‐based behavioral intervention that taught parents to use child behavior management strategies to increase healthy eating and activity for their children and themselves. PC presented the same diet and activity recommendations, but was delivered in a one‐time PC session. Eighteen children aged 2–5 years (mean 4.71 ± 1.01) with an average BMI percentile of 98 (±1.60) and an overweight parent were randomized to LAUNCH or PC. Assessments were conducted at baseline, 6 months (end of LAUNCH treatment) and 12 months (6 months following LAUNCH treatment). LAUNCH showed a significantly greater decrease on the primary outcomes of child at month 6 (post‐treatment) BMI z (?0.59 ± 0.17), BMI percentile (?2.4 ± 1.0), and weight gain (?2.7 kg ± 1.2) than PC and this difference was maintained at follow‐up (month 12). LAUNCH parents also had a significantly greater weight loss (?5.5 kg ± 0.9) at month 6 and 12 (?8.0 kg ± 3.5) than PC parents. Based on the data from this small sample, an intensive intervention that includes child behavior management strategies to improve healthy eating and activity appears more promising in reducing preschool obesity than a low intensity intervention that is typical of treatment that could be delivered in primary care.     

Body Dissatisfaction and Binge Eating in Obese Women: The Role of Restraint and Depression

Objective: This study examined the association between body dissatisfaction and binge eating, and the mediating role of restraint and depression among obese women. Research Methods and Procedures: Participants were obese women taking part in a cognitive-behavioral treatment program who completed self-report measures at baseline (n = 89) and post-treatment follow-up (n = 69). Results: At baseline, body dissatisfaction was strongly correlated with binge eating score. This was partly a direct effect and partly mediated by depression. No mediating effect of restraint was observed. Over the treatment period, a reduction in body dissatisfaction was associated with a reduction in binge-eating score. As in the cross-sectional data, there was evidence for mediation by change in depression with the greatest improvement in binge eating among those who became more restrained and less depressed. Discussion: These results suggest that it would be valuable to address psychological well-being, and especially body image, as part of the management of binge-eating behavior in obesity.     

Obesity and impairment in psychosocial functioning in women: the mediating role of eating disorder features

Objective: The objective was to test the hypothesis that, in women, the association between obesity and impairment in psychosocial functioning is mediated by levels of weight and shape concerns and/or binge‐eating frequency. Research Methods and Procedures: Self‐report measures of eating disorder psychopathology, mental health functioning, subjective quality of life in the psychological and social domains, and days “out‐of‐role” associated with any (physical or mental) health problem, were completed by a community sample of women classified as obese (BMI ≥30 kg/m², n = 639) or non‐obese (BMI <30 kg/m², n = 4253). For each of the dependent measures, regression models were used to test the hypothesis of mediation by comparing the strength of the relationship between independent and dependent variables with and without inclusion of the putative mediator in the regression model. Results: On each measure, the conditions for perfect mediation were satisfied when weight or shape concerns acted as the putative mediator, indicating that there was no association between obesity and functional impairment after controlling for weight or shape concerns. In contrast, associations between obesity and impairment in psychosocial functioning remained highly significant when binge‐eating frequency was the putative mediator. Discussion: The findings suggest that in women, weight and shape concerns are an important mediator of the relationship between obesity and impairment in psychosocial functioning, whereas binge eating may not be of primary importance. A greater focus on body acceptance in obesity treatment may be indicated.     

Eating Frequency is Associated With Energy Intake but Not Obesity in Midlife Women

Midlife women tend to gain weight with age, thus increasing risk of chronic disease. The purpose of this study was to examine associations between overweight/obesity and behavioral factors, including eating frequency, in a cross‐sectional national sample of midlife women (n = 1,099) (mean age = 49.7 years, and BMI = 27.7 kg/m²). Eating behaviors and food and nutrient intakes were based on a mailed 1‐day food record. BMI was calculated from self‐reported height and weight, and level of physical activity was assessed by self‐reported questionnaire. After exclusion of low‐energy reporters (32% of sample), eating frequency was not associated with overweight/obesity (P > 0.05) and was not different between BMI groups (normal, 5.21 ± 1.79; overweight, 5.16 ± 1.74; obese, 5.12 ± 1.68, P = 0.769). Adjusted logistic regression showed that eating frequency, snacking frequency, breakfast consumption, eating after 10 pm and consuming meals with children or other adults were not significantly associated with overweight/obesity. Total energy intake increased as eating frequency increased in all BMI groups, however, obese women had greater energy intake compared to normal weight women who consumed the same number of meals and snacks. Intake of fruit and vegetables, whole grains, dietary fiber, dairy, and added sugars also increased as eating frequency increased. While eating frequency was not associated with overweight/obesity, it was associated with energy intake. Thus, addressing total energy intake rather than eating frequency may be more appropriate to prevent weight gain among midlife women.     

Effect of orlistat on eating behavior among participants in a 3-year weight maintenance trial

Objective: To examine the effect of orlistat on dietary restraint, disinhibition, hunger, and binge eating and to understand the relation between changes in eating behavior and weight maintenance. Methods and Procedures: Subjects were 306 women and men (age: 19–45 years; BMI: 37.5 ± 4.1 kg/m²) included in the Scandinavian Multicenter study of Obese subjects with the Metabolic Syndrome, a 3‐year clinical trial of orlistat or placebo following an 8‐week very low energy diet (VLED). Outcomes were changes in weight and in the Three Factor Eating Questionnaire (TFEQ) and Binge Eating Scale (BES) between screening and 17 and 33 months after randomization. As reported previously, weight gain following VLED was lower in subjects treated with orlistat than with placebo. Results: Compared to screening results, dietary restraint was increased and disinhibition, hunger, and binge eating were decreased in both groups. These changes were similar in both groups with the exception of the hunger score at month 33 that was reduced more in the placebo than in the orlistat group (difference between groups ?1.1 (95% CI (?2.0, ?0.2)) P = 0.014). In multivariate analyses, scores for restraint, disinhibition and binge eating were associated with weight loss after adjustment for BMI, gender, age, and treatment (all P ≤ 0.002, model R ² = 0.12–0.17). Discussion: Orlistat did not affect eating behavior differently in any substantial way than the placebo did in this long‐term weight maintenance trial. The results indicate that increased restraint and decreased disinhibition and binge eating are important for sustained weight maintenance in obese subjects with the metabolic syndrome.     

High allelic burden of four obesity SNPs is associated with poorer weight loss outcomes following gastric bypass surgery

Genome‐wide association and linkage studies have identified multiple susceptibility loci for obesity. We hypothesized that such loci may affect weight loss outcomes following dietary or surgical weight loss interventions. A total of 1,001 white individuals with extreme obesity (BMI >35 kg/m²) who underwent a preoperative diet/behavioral weight loss intervention and Roux‐en‐Y gastric bypass surgery were genotyped for single‐nucleotide polymorphisms (SNPs) in or near the fat mass and obesity‐associated (FTO), insulin induced gene 2 (INSIG2), melanocortin 4 receptor (MC4R), and proprotein convertase subtilisin/kexin type 1 (PCSK1) obesity genes. Association analysis was performed using recessive and additive models with pre‐ and postoperative weight loss data. An increasing number of obesity SNP alleles or homozygous SNP genotypes was associated with increased BMI (P < 0.0006) and excess body weight (P < 0.0004). No association between the amounts of weight lost from a short‐term dietary intervention and any individual obesity SNP or cumulative number of obesity SNP alleles or homozygous SNP genotypes was observed. Linear mixed regression analysis revealed significant differences in postoperative weight loss trajectories across groups with low, intermediate, and high numbers of obesity SNP alleles or numbers of homozygous SNP genotypes (P < 0.0001). Initial BMI interacted with genotype to influence weight loss with initial BMI <50 kg/m², with evidence of a dosage effect, which was not present in individuals with initial BMI ≥50 kg/m². Differences in metabolic rate, binge eating behavior, and other clinical parameters were not associated with genotype. These data suggest that response to a surgical weight loss intervention is influenced by genetic susceptibility and BMI.     

Leptin Responses to Weight Loss in Postmenopausal Women: Relationship to Sex‐Hormone Binding Globulin and Visceral Obesity

Objective: Leptin concentrations increase with obesity and tend to decrease with weight loss. However, there is large variation in the response of serum leptin levels to decreases in body weight. This study examines which endocrine and body composition factors are related to changes in leptin concentrations following weight loss in obese, postmenopausal women. Research Methods and Procedures: Body composition (DXA), visceral obesity (computed tomography), leptin, cortisol, insulin, and sex hormone‐binding globulin (SHBG) concentrations were measured in 54 obese (body mass index [BMI] = 32.0 ± 4.5 kg/m²; mean ± SD), women (60 ± 6 years) before and after a 6‐month hypocaloric diet (250 to 350 kcal/day deficit). Results: Body weight decreased by 5.8 ± 3.4 kg (7.1%) and leptin levels decreased by 6.6 ± 11.9 ng/mL (14.5%) after the 6‐month treatment. Insulin levels decreased 10% (p < 0.05), but mean SHBG and cortisol levels did not change significantly. Relative changes in leptin with weight loss correlated positively with relative changes in body weight (r = 0.50, p < 0.0001), fat mass (r = 0.38, p < 0.01), subcutaneous fat area (r = 0.52, p < 0.0001), and with baseline values of SHBG (r = 0.38, p < 0.01) and baseline intra‐abdominal fat area (r = ?0.27, p < 0.06). Stepwise multiple regression analysis showed that baseline SHBG levels (r² = 0.24, p < 0.01), relative changes in body weight (cumulative r² = 0.40, p < 0.05), and baseline intra‐abdominal fat area (cumulative r² = 0.48, p < 0.05) were the only independent predictors of the relative change in leptin, accounting for 48% of the variance. Discussion: These results suggest that obese, postmenopausal women with a lower initial SHBG and more visceral obesity have a greater decrease in leptin with weight loss, independent of the amount of weight lost.     

Binge eating and weight loss in a self-help behavior modification program

Objective: To examine the occurrence of binge eating and its impact on weight loss outcomes among obese participants in the Trevose Behavior Modification Program, a lay‐administered, lay‐directed self‐help weight loss program offering continuing care. Research Methods and Procedures: Participants completed questionnaires, and weight loss data were recorded prospectively. Results: Although objective bulimic episodes were reported by 41% of the sample, objective bulimic episodes were not associated with worse weight loss outcomes. Mean weight loss after 12 months was 18.2 kg (18.8% of initial body weight) for the treatment completers and 10.3 kg (10.5% of initial body weight) for the full sample (using intent‐to‐treat analyses, with baseline scores carried forward). Discussion: Substantial long‐term weight loss, resulting from a continuing care treatment program, occurred in individuals both with and without frequent binge eating.     

Grazing and loss of control related to eating: two high-risk factors following bariatric surgery

Background: Gastric restrictive surgery induces a marked change in eating behavior. However, the relationship between preoperative and postoperative eating behavior and weight loss outcome has received limited attention. Objective: This study assessed a range of eating behaviors before and 1 year after laparoscopic adjustable gastric banding (LAGB) and explored the nature and extent of change in eating patterns, their clinical associates, and impact on weight loss. Methods and Procedures: A 12‐month observational study assessed presurgical and postsurgical binge eating disorder (BED), uncontrolled eating, night eating syndrome (NES), grazing, nutrient intake and eating‐related behaviors, and markers of psychological distress. A total of 129 subjects (26 male and 103 female, mean age 45.2 ± 11.5 and BMI 44.3 ± 6.8) participated in this study. Results: Presurgical BED, uncontrolled eating, and NES occurred in 14%, 31%, and 17.1% of subjects, which reduced after surgery to 3.1%, 22.5%, and 7.8%, respectively (P = 0.05 for all). Grazing was prevalent before (26.3%) and after surgery (38.0%). Preoperative BED most frequently became grazers (P = 0.029). The average percentage weight loss (%WL) was 20.8 ± 8.5%; range ?0.67 to 50.0% and percentage of excess weight loss (%EWL) 50.0 ± 20.7%; range ?1.44 to 106.9% (P < 0.001). Uncontrolled eating and grazing after surgery showed high overlap and were associated with poorer %WL (P = 0.008 and P < 0.001, respectively) and elevated psychological distress. Discussion: Consistent with recent studies, uncontrolled eating and grazing were identified as two high‐risk eating patterns after surgery. Clearer characterization of favorable and unfavorable postsurgical eating behaviors, reliable methods to assess their presence, and empirically tested postsurgical intervention strategies are required to optimize weight loss outcomes and facilitate psychological well‐being in at‐risk groups.     

Gender Differences in Shame in Patients with Binge‐Eating Disorder

Objective: To examine the relationship between shame and the behavioral and attitudinal features of eating disorders in men and women diagnosed with binge‐eating disorder (BED). Research Methods and Procedures: Participants were 188 consecutively evaluated adults (38 men and 150 women) who met Diagnostic and Statistical Manual of Mental Disorders, 4th edition, criteria for BED. Participants were interviewed and completed a battery of measures assessing shame, behavioral and attitudinal features of eating disorders, and general psychological functioning. Results: Shame did not differ significantly by gender and was not associated with BMI or binge‐eating frequency. Shame was significantly associated with the attitudinal features of eating disorders, even after controlling for levels of depression and self‐esteem. When considered separately by gender and controlling for depression and self‐esteem, shame was associated with body dissatisfaction in men and with weight concern in women. Discussion: Men and women with BED, who presented for treatment, reported similar levels of shame. Overall, while shame was related to attitudinal features, the specific associations differed by gender. For men, shame was related to how dissatisfied they felt with their bodies, whereas for women, shame was associated with concerns about weight. Interestingly, shame was not related to BMI or binge‐eating frequency in men or women. These results provide preliminary support for self‐conscious emotions playing different roles in men and women with BED.
