Binge eating and dietary restraint in obese patients

The relationship between difficulties in the regulation of positive and negative emotions and binge-eating symptoms in young adults

It is well-established that binge-eating (BE) is linked to emotion regulation (ER) difficulties. However, research to date has focused almost exclusively on difficulties regulating negative emotions, with little attention to the relationship between positive emotion dysregulation and BE. Further, research is inconclusive regarding which specific facets of ER difficulties are most strongly associated with BE behaviour. Therefore, the current study examined whether difficulties regulating both negative as well as positive emotions explained unique variance in BE among young adults. The study also aimed to identify which particular dimensions of negative and positive ER difficulties were most strongly related to BE symptoms. Participants (N = 449) ages 18-25 completed self-report measures of difficulties regulating positive and negative emotions, BE symptoms, and psychological distress. Hierarchical regression analyses showed that BE was related to difficulties regulating both positive emotions and negative emotions, after controlling for psychological distress and BMI. Lack of emotional clarity and lack of access to ER strategies when faced with strong negative emotions were the facets of negative ER difficulties most strongly associated with BE. Impulsivity when experiencing strong positive emotions was the facet of positive ER difficulties most strongly associated with BE. These findings support the ER model of BE and suggest that difficulties regulating both positive and negative emotions contribute to BE among young adults.

Reconsidering the role of interpersonal stress in eating pathology: Sensitivity to rejection might be more important than actual experiences of peer stress

Rejection sensitivity (i.e., the tendency to anxiously expect, readily perceive, and overreact to real or perceived rejection) is theorized to play a role in the onset and maintenance of disordered eating. Although rejection sensitivity has repeatedly been associated with eating pathology in clinical and community samples, the pathways through which this psychological trait influences eating pathology have been not fully established. The current study investigated peer-related stress, which can be influenced by rejection sensitivity and is associated with eating pathology, as a mechanism linking these constructs. In two samples of women - 189 first-year undergraduate students and 77 community women with binge eating - we examined whether rejection sensitivity was indirectly associated with binge eating and weight/shape concerns via ostracism and peer victimization, both cross-sectionally and longitudinally. Our hypotheses were not supported: there were no indirect associations between rejection sensitivity and eating pathology via interpersonal stress in either sample. However, we did find that rejection sensitivity was directly associated with weight/shape concerns in both samples and with binge eating in the clinical sample in cross-sectional (but not longitudinal) analyses. Our findings suggest that the association between rejection sensitivity and disordered eating is not dependent on actual experiences of interpersonal stress. That is, simply anticipating or perceiving rejection may be sufficient to play a role in eating pathology. As such, interventions targeting rejection sensitivity may be helpful in the treatment of eating pathology.

Low eating self-efficacy is associated with unfavorable eating behavior tendencies among individuals with overweight and obesity

Success in long-term weight management depends partly on psychological and behavioral aspects. Understanding the links between psychological factors and eating behavior tendencies is needed to develop more effective weight management methods. This population-based cross-sectional study examined whether eating self-efficacy (ESE) is associated with cognitive restraint (CR), uncontrolled eating (UE), emotional eating (EE), and binge eating (BE). The hypothesis was that individuals with low ESE have more unfavorable eating behavior tendencies than individuals with high ESE. Participants were classified as low ESE and high ESE by the Weight-Related Self-Efficacy questionnaire (WEL) median cut-off point. Eating behavior tendencies were assessed with Three Factor Eating Questionnaire R-18 and Binge Eating Scale, and additionally, by the number of difficulties in weight management. The difficulties were low CR, high UE, high EE, and moderate or severe BE. Five hundred and thirty-two volunteers with overweight and obesity were included in the study. Participants with low ESE had lower CR (p < 0.03) and higher UE, EE, and BE (p < 0.001) than participants with high ESE. Thirty-nine percent of men with low ESE had at least two difficulties in successful weight control while this percentage was only 8% in men with high ESE. In women, the corresponding figures were 56% and 10%. The risk of low ESE was increased by high UE [OR 5.37 (95% CI 1.99-14.51)], high EE [OR 6.05 (95% CI 2.07-17.66)], or moderate or severe BE [OR 12.31 (95% CI 1.52-99.84)] in men, and by low CR [OR 5.19 (95% CI 2.22-12.18)], high UE [OR 7.20 (95% CI 2.41-19.22)], or high EE [OR 23.66 (95% CI 4.79-116.77)] in women. Low ESE was associated with unfavorable eating behavior tendencies and multiple concomitant difficulties in successful weight loss promotion. These eating behavior tendencies should be considered when counseling patients with overweight and obesity.

Craving for carbs: food craving and disordered eating in low-carb dieters and its association with intermittent fasting

Studies point to positive outcomes in a diet with reduction of carbohydrates and that the associated practice of intermittent fasting (IF) might increase weight loss. Although dieting might be related to disordered eating, little evidence is available about the role of restrictive carbohydrates diets on disordered eating. This study aimed to explore if doing low-carb (LC) diets was related to disordered eating and if IF would increase these symptoms. The sample comprised university students (n = 682), with a mean age of 22 years old and average BMI of 23.6 kg/m2 (SD = 4.3). Twenty-seven percent (n = 188) of respondents reported doing LC diet in the last three months. Of those, 31% (n = 58) reported doing LC diet combined with periods of IF. Mean scores were compared using parametric tests, and effects size and correlations between variables were calculated. Dieters showed higher levels of binge eating, food cravings, cognitive restraint, cognitive restraint toward carbohydrates when compared to non-dieters. The association of LC and IF was related to an increase in disordered eating, especially binge eating and food cravings, specifically 'Lack of control', 'Thoughts or preoccupation with food,' and 'Guilt from cravings and/or for giving in to them'. These results provide evidence that restrictive carbohydrate diets and IF may increase cognitive restraint and, consequently, food cravings.Level III: Evidence obtained from cohort or case-control analytic studies.

The manifestation of emotional distress: Correlations between self-compassion and self-mutilation in Brazilian women with disordered eating behavior

BACKGROUND

The functions or motives for self-mutilation behavior (SMB) in Eating Disorders are diverse, and the relationship with self-compassion is unclear. Objectives This study aims to evaluate the relationship between SMB and Self-compassion.

METHODS

251 women aged 25.8 years (SD=5.94) and 73.54kg (SD=19.33) completed measures for Binge Eating (BE), Self-Compassion, and SMB.

RESULTS

In the total evaluated, 83.27% (n=209) presented BE and 94.02% (n=236) presented at least 1 type of SMB. In comparison between groups, the BE-purging one's reached higher values for BE, and less self-compassion, while BE group presented higher self-compassion values. For the BE-purging group, the behaviors "Cut or carving skin", "Hitting self", "Pulling out one's hair", "Burning skin" and "Picking areas of the body to the point of drawing blood" showed inverse correlations with self-compassion.

CONCLUSION

There is an inverse correlation between self-compassion and SMB, and SMB seems to have different functions between BE-purging group vs. BE group.

Evaluating functional disability in clinical trials of lisdexamfetamine dimesylate in binge eating disorder using the Sheehan Disability Scale

OBJECTIVES

This study examined Sheehan Disability Scale (SDS) performance in binge eating disorder (BED) and explored relationships between SDS and BED outcomes using data from three placebo-controlled lisdexamfetamine (LDX) studies (two short-term, dose-optimized studies and one double-blind, randomized-withdrawal study) in adults with Diagnostic and Statistical Manual of Mental Disorders, fourth edition, text revision (DSM-IV-TR)-defined BED.

METHODS

Analyses evaluated the psychometric properties of the SDS.

RESULTS

Confirmatory factor analysis supported a unidimensional total score in the short-term studies, with internal consistency (Cronbach's α) being 0.878. Total score exhibited good construct validity, with moderate and statistically significant correlations observed with Yale-Brown Obsessive Compulsive Scale modified for binge eating, Binge Eating Scale (BES), and EuroQol Group 5-Dimension 5-Level health status index scores. Known-groups validity analysis for the short-term studies demonstrated a significantly lower total score at end of study in participants considered "not ill" versus "ill" based on Clinical Global Impressions-Severity scores. SDS total score changes in the short-term studies were greater in responders than nonresponders based on binge eating abstinence or BES score. In the randomized-withdrawal study, SDS scores increased relative to baseline to a greater extent in participants randomized to placebo than LDX.

CONCLUSIONS

These analyses support the reliability, validity, and responsiveness to change of the SDS in individuals with BED.

Existe uma relação entre autocompaixão e adição à comida em mulheres com comportamentos alimentares disfuncionais?

RESUMO Objetivo: Verificar a relação entre autocompaixão e adição à comida em mulheres com comportamento alimentar disfuncional. Métodos: Mulheres de um grupo de apoio completaram as escalas de compulsão alimentar, restrição cognitiva, autocompaixão, Escala de Adição à Comida de Yale versão modificada 2.0 (YFAS 2.0) e questionário de Hay para práticas compensatórias. Foram identificados a prevalência de adição à comida e sintomas segundo a YFAS. Para serem incluídas, as participantes deveriam atingir pontuação para compulsão alimentar e, para análises, foram divididas em função da presença de práticas compensatórias. O grupo foi analisado por meio de testes de correlação de Pearson entre variáveis de interesse, e os grupos bulímico e compulsivo foram comparados com teste t de Student (p < 0,05; software JASP). Resultados: Participaram do estudo 190 mulheres. De acordo com a YFAS, 95,3% (n = 181) tinham adição à comida, e os escores da escala apresentaram correlação negativa com a autocompaixão e com a compulsão alimentar (p = 0,014 em ambas). Os níveis de autocompaixão apresentaram correlação negativa com as questões #3, #5, #6, #8 e #9 da YFAS (p < 0,05). Conclusões: Este estudo traz dados para a discussão da necessidade de analisar como a autocrítica atrelada ao sofrimento de quem apresenta comportamento alimentar disfuncional afeta o preenchimento da escala, trazendo identificação com a noção de vício, já que esta é culturalmente aceita.

The Homeostatic Theory of Obesity: An Empirical Verification of the Circle of Discontent with an Assessment of Its Relationship to Restrained and Uncontrolled Eating among Children and Adolescents

The purpose of the present study was to provide an empirical verification of the Circle of Discontent with an assessment of its relationship to restrained and uncontrolled eating among children and adolescents. This study examined whether our results confirm a new hypothesized model. The total sample comprised 282 children and adolescents (148 girls and 134 boys; 141 participants with normal body weight and 141 with obesity). The mean age was 12.23 years (SD = 2.80), and the average BMI (body mass index) was 23.29 kg/m² (SD = 6.27). The following were used: Positive and Negative Affect Scale for Children, Children’s Body Image Scale, Figure Rating Scale, Three-Factor Eating Questionnaire and Eating Disorders in Youth. The obtained values of the model fit indices proved the goodness of fit. Our findings show that obesity accompanies body dissatisfaction and uncontrolled and restrictive eating. Moreover, the higher the level of restrictive eating, the lower the level of uncontrolled eating. The relationships between body dissatisfaction, negative affect and restrictive eating, as well as that between uncontrolled eating and high-energy consumption, are significant and positive. Other relationships are non-significant. The above-mentioned relationships established in the Circle of Discontent, as well as relationships of restrained and uncontrolled eating with variables described in the circle, were confirmed. Based on our results, preventive strategies and psychological interventions can be created and may include changes in body image, eating behaviors and emotional functioning.

Predictive utility of subtyping women smokers on depression, eating, and weight-related symptoms

OBJECTIVE

Smoking and overweight or obesity are preventable causes of disease and death. Women are reluctant to quit smoking because of concerns about postcessation weight gain, underscoring the need to elucidate patterns of weight concerns and associated psychosocial factors that may affect smoking cessation outcomes. The present study aimed to subtype women smokers based on psychosocial and behavioral factors associated with smoking and weight, and examine the utility of these subtypes to predict abstinence and postcessation weight gain.

METHOD

Weight-concerned women (N = 343) were randomized to 1 of 2 smoking cessation counseling adjuncts and 1 of 2 cessation medication conditions. At baseline, women were weighed and completed measures of depression, weight or appearance concerns, and eating behaviors. At 3-, 6-, and 12-months after the target quit date, women were weighed and completed self-report and biochemical smoking assessments.

RESULTS

Latent profile (LP) analyses supported a 3-profile model. The groups had typical (53%, LP1), minimal (33%, LP2), and high (14%, LP3) levels of depressive symptoms and weight concerns. At 12-months posttarget quit date, women in LP3 were more likely to relapse than women in LP1 (odds ratio, OR = 2.93). Among abstinent women, those in LP2 and LP3 gained more postcessation weight than those in LP1.

CONCLUSIONS

Heterogeneity in symptoms of depression, weight or appearance concerns, and eating behaviors was captured by three groups of women smokers, with unique risks for relapse and postcessation weight gain. The distinct profiles identified may help personalize the delivery of care for smoking cessation and, ultimately, reduce disease risk. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Pilot study of the prevalence of binge eating disorder in non-alcoholic fatty liver disease patients

Background

Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease in the United States. Binge eating disorder (BED) is the most common form of eating disorder. NAFLD and BED have similar risk factors, including obesity, insulin resistance, and metabolic syndrome. The aim of our study was to examine prevalence of BED in NAFLD patients.

Methods

We administered the Binge Eating Scale (BES), a questionnaire validated to screen for BED, to NAFLD patients at our Fatty Liver Center. Demographics were retrieved retrospectively from our electronic medical record.

Results

Of the total 95 NAFLD patients screened, 22 (23.1%) had binge eating tendencies; 6 of the 22 (6.3%) scored 27 or more points, suggestive of severe binge eating. Patient demographics included 59 females and 36 males (14 females and 8 males positive for BED). Liver disease severity and of metabolic syndrome presence were similar in both groups: 45 patients had steatosis, 25 steatohepatitis, and 24 cirrhosis, of which 10 steatosis, 5 steatohepatitis, and 7 cirrhosis patients screened positive for BED. Of the NAFLD patients with BED, 50.0% had insulin resistance, 68.2% hypertension, and 50.0% hyperlipidemia, whereas among non-BED NAFLD patients 58.9% had insulin resistance, 63.0% hypertension, and 67.1% hyperlipidemia.

Conclusions

This pilot study suggests that BED may have a higher prevalence among NAFLD patients than in the general population. Based on these preliminary results, further study into the prevalence of BED is recommended. More data is need to identify effects of BED on the progression of NAFLD and role of BED treatment.

An Open Trial Targeting Food Cue Reactivity and Satiety Sensitivity in Overweight and Obese Binge Eaters

Data suggests that individuals who binge eat are more responsive to food cues in the environment and less sensitive to satiety cues. The aim of this open trial was to evaluate the feasibility, acceptability, and initial effectiveness of a novel treatment grounded in Schachter's externality theory targeting food cue reactivity and satiety responsiveness with obese adults who binge eat. Treatment was provided in groups, and utilized appetite monitoring, cue-exposure treatment, in vivo exercises, self-monitoring, and coping skills. Twenty-eight overweight and obese adults who binge eat (82% female; mean age = 47.5 years [SD = 12.8]; BMI = 38.9 [SD = 10.3]; 79% White non-Hispanic) participated in a 4-month group-based treatment program. Assessments were conducted at baseline, posttreatment, and 3-month follow-up time points. Results indicated that this treatment was well accepted and had high retention at posttreatment. Initial effectiveness showed significant decreases in BMI, and improvements in loss of control and overeating episodes, food responsiveness, and power of food. The majority of results were maintained at the 3-month follow-up time point. This open trial provides preliminary evidence for the feasibility, acceptability, and initial effectiveness of this treatment on both eating disorder symptoms and weight in obese adults who binge eat. Because these data are preliminary, further treatment development and randomized controlled studies are needed.

Self-perceived food addiction: Prevalence, predictors, and prognosis

Food addiction is controversial within the scientific community. However many lay people consider themselves addicted to certain foods. We assessed the prevalence and characteristics of self-perceived "food addiction" and its relationship to a diagnostic measure of "clinical food addiction" in two samples: (1) 658 university students, and (2) 614 adults from an international online crowdsourcing platform. Participants indicated whether they considered themselves to be addicted to food, and then completed the Yale Food Addiction Scale, measures of eating behavior, body image, and explicit and internalized weight stigma. Participants in the community sample additionally completed measures of impulsivity, food cravings, binge eating, and depressive symptomatology. Follow-up data were collected from a subset of 305 students (mean follow-up 280 ± 30 days). Self-perceived "food addiction" was prevalent, and was associated with elevated levels of problematic eating behavior, body image concerns, and psychopathology compared with "non-addicts", although individuals who also received a positive "diagnosis" on the Yale Food Addiction Scale experienced the most severe symptoms. A clear continuum was evident for all measures despite no differences in body mass index between the three groups. Multinomial logistic regression analyses indicated that perceived lack of self-control around food was the main factor distinguishing between those who did and did not consider themselves addicted to food, whereas severity of food cravings and depressive symptoms were the main discriminating variables between self-classifiers and those receiving a positive "diagnosis" on the Yale Food Addiction Scale. Self-perceived "food addiction" was moderately stable across time, but did not appear predictive of worsening eating pathology. Self-classification as a "food addict" may be of use in identifying individuals in need of assistance with food misuse, loss-of-control eating, and body image issues.

BEfree: A new psychological program for binge eating that integrates psychoeducation, mindfulness, and compassion

Binge eating disorder (BED) is associated with several psychological and medical problems, such as obesity. Approximately 30% of individuals seeking weight loss treatments present binge eating symptomatology. Moreover, current treatments for BED lack efficacy at follow‐up assessments. Developing mindfulness and self‐compassion seem to be beneficial in treating BED, although there is still room for improvement, which may include integrating these different but complimentary approaches. BEfree is the first program integrating psychoeducation‐, mindfulness‐, and compassion‐based components for treating women with binge eating and obesity.

Objective

To test the acceptability and efficacy up to 6‐month postintervention of a psychological program based on psychoeducation, mindfulness, and self‐compassion for obese or overweight women with BED.

Design

A controlled longitudinal design was followed in order to compare results between BEfree (n = 19) and waiting list group (WL; n = 17) from preintervention to postintervention. Results from BEfree were compared from preintervention to 3‐ and 6‐month follow‐up.

Results

BEfree was effective in eliminating BED; in diminishing eating psychopathology, depression, shame and self‐criticism, body‐image psychological inflexibility, and body‐image cognitive fusion; and in improving obesity‐related quality of life and self‐compassion when compared to a WL control group. Results were maintained at 3‐ and 6‐month follow‐up. Finally, participants rated BEfree helpful for dealing with impulses and negative internal experiences.

Conclusions

These results seem to suggest the efficacy of BEfree and the benefit of integrating different components such as psychoeducation, mindfulness, and self‐compassion when treating BED in obese or overweight women.

Key Practitioner Message

The current study provides evidence of the acceptability of a psychoeducation, mindfulness, and compassion program for binge eating in obesity (BEfree);

Developing mindfulness and self‐compassionate skills is an effective way of diminishing binge eating, eating psychopathology and depression, and increasing quality of life in women with obesity;

Integrating psychoeducation, mindfulness, and compassion seem to be effective in diminishing binge eating, with results maintained up to 6‐month postintervention.

Severe obesity, emotions and eating habits: a case-control study

BACKGROUND

Obesity has a multifaceted etiology that involves genetic, biological and behavioral factors, body growth, eating habits, energy expenditure and the function of adipose tissue. The present study aimed to expand upon knowledge about the relationships among obesity, emotions and eating habits in severely obese individuals using a case-control method.

METHODS

The subject group consisted of 112 individuals (81 females and 31 males) receiving a permanent disability pension primarily for obesity. The control subjects were randomly selected from the same area and were receiving a disability pension for a different primary illness. The controls were matched with the subjects by the place of residence, sex, age, the time since the pension was granted and occupation. Psychiatric interviews were conducted on all participants. The results were analyzed using the chi-squared test (χ²-test) and the percent distribution. The subject and control groups were compared using the t-test for paired variables. Conditional logistic regression analysis was also conducted.

RESULTS

The emotional state of eating was significantly associated with quarrels and feelings of loneliness. The subjects suffered from night eating syndrome, which was associated with an increased risk of early retirement. Binge eating syndrome was observed more frequently in the study group. The subjects reported feeling increased hunger compared with the controls. A significant percentage of the subjects had a body mass index of ≥ 40. No differences in eating habits were observed between the groups.

CONCLUSION

This study provides information on the relationship between emotions and eating habits in obesity, which is a rarely studied topic. We believe that our study provides a novel and necessary overview of the associations among severe obesity, emotions and eating habits.

Incorporating psychoeducation, mindfulness and self-compassion in a new programme for binge eating (BEfree): Exploring processes of change

This study explores the efficacy of BEfree, a 12-session group intervention that integrates psychoeducation, mindfulness, compassion and value-based action, in a sample of overweight and obese women with binge eating disorder ( N = 31). We used repeated measures analyses of variance and explored processes of change in binge eating and eating psychopathology. At post-intervention, participants decreased in binge eating severity, eating psychopathology, external shame, self-criticism, psychological inflexibility, body image cognitive fusion and increased self-compassion and engagement with valued actions. These results were maintained at 3- and 6-month follow-up. The changes in binge eating were mediated by the changes in the psychological processes promoted by BEfree.

Dietary Restraint Partially Mediates the Relationship between Impulsivity and Binge Eating Only in Lean Individuals: The Importance of Accounting for Body Mass in Studies of Restraint

Binge eating is characteristic of eating and weight-related disorders such as binge eating disorder, bulimia nervosa, and obesity. In light of data suggest impulsivity is associated with overeating specifically in restrained eaters, this study sought to elucidate the exact nature of the associations between these variables, hypothesizing that the relationship between impulsivity and binge eating is mediated by restrained eating. We further hypothesized that the role of dietary restraint as a mediator would be moderated by body mass index (BMI). Study participants (n = 506, 50.6% female) were categorized based on self-reported BMI as under- and normal-weight (BMI < 25, 65.8%, n = 333) or overweight and obese (BMI ≥ 25, 34.2%, n = 173) and completed the “restrained eating” subscale of the Dutch Eating Behavior Questionnaire, the “impulse control difficulties” subscale of the Difficulties with Emotion Regulation Scale, and the Binge Eating Scale. Findings provide initial evidence for the hypothesized moderated mediation model, with dietary restraint partially mediating the relationship between impulsivity and binge eating severity only in lean respondents. In respondents with overweight or obesity, impulsivity was significantly correlated with binge eating severity, but not with dietary restraint. Findings inform our conceptualization of dietary restraint as a possible risk factor for binge eating and highlight the importance of accounting for body mass in research on the impact of dietary restraint on eating behaviors.

An open trial evaluating an attention bias modification program for overweight adults who binge eat

BACKGROUND AND OBJECTIVES

Binge eating is prevalent and is associated with significant psychiatric and medical comorbidities. To date, the most effective psychological treatments for individuals who binge eat are not effective for all patients and they do not result in significant weight loss. Dual process theories suggest that implicit factors, such as attention bias, may influence behavior, even when the behavior is in opposition to long-term goals. Attention bias modification programs have been tested in other areas of psychopathology, and could be utilized to improve outcomes for people who binge eat. Thus, the aim of this open trial was to conduct a preliminary evaluation of an attention bias modification program (ABM-Food) designed to train attention away from food cues.

METHODS

Adults who binge eat and were overweight or obese enrolled in an 8-week ABM-Food program, which consisted of one session in the lab each week and two training sessions at home. Nine participants completed the ABM-Food training program and the post-treatment assessment, and 8 completed the 3-month post-treatment assessment.

RESULTS

Results showed that the ABM-Food program is a feasible and acceptable treatment for adults who binge eat. Initial effectiveness data showed decreases in weight, eating disorder symptoms, binge eating, loss of control and responsivity to food in the environment, as well as changes in attention bias. The majority of these effects remained at the 3-month follow-up time point.

LIMITATIONS

This study is limited by the single-group open label trial, and the small sample size.

CONCLUSIONS

This open trial provides initial evidence for the feasibility, acceptability and effectiveness of ABM-Food for individuals who binge eat and are overweight or obese.

Expanding binge eating assessment: Validity and screening value of the Binge Eating Scale in women from the general population

There is growing recognition that binge eating is a prevalent problem with serious implications for both clinical and nonclinical samples. The current study aimed at examining the factor structure, psychometric properties and the screening usefulness of the Binge Eating Scale (BES) in a large sample of female college students and women from the Portuguese general population. A sample of 1008 participants was collected to conduct a confirmatory factor analysis and test the BES psychometric properties; 150 participants were further evaluated through the Eating Disorder Examination 16.0D to assess the discriminant validity of the BES. Results confirmed that the BES presents a sound one-dimensional factorial structure, with very good construct reliability and convergent validity. Also, the scale presented very good retest-reliability. Findings also offered evidence that the BES is positively associated with measures of eating and general psychopathology, and BMI. Furthermore, the BES revealed an excellent performance (96.7%) on discriminating clinically significant cases of binge eating, showing a sensitivity of 81.8% and a specificity of 97.8%. Results support the validity and usefulness of the BES as an assessment and screening tool for binge eating in women from the general population.

Homeostatic theory of obesity

Health is regulated by homeostasis, a property of all living things. Homeostasis maintains equilibrium at set-points using feedback loops for optimum functioning of the organism. Imbalances in homeostasis causing overweight and obesity are evident in more than 1 billion people. In a new theory, homeostatic obesity imbalance is attributed to a hypothesized 'Circle of Discontent', a system of feedback loops linking weight gain, body dissatisfaction, negative affect and over-consumption. The Circle of Discontent theory is consistent with an extensive evidence base. A four-armed strategy to halt the obesity epidemic consists of (1) putting a stop to victim-blaming, stigma and discrimination; (2) devalorizing the thin-ideal; (3) reducing consumption of energy-dense, low-nutrient foods and drinks; and (4) improving access to plant-based diets. If fully implemented, interventions designed to restore homeostasis have the potential to halt the obesity epidemic.

Family Environment and Psychiatric History in Women with Binge-eating Disorder and Obese Controls

We examined the prevalence of comorbid psychopathology, family psychiatric history, and perceptions of family environment in 20 women with binge-eating disorder (BED) and 20 non-binge-eating obese controls. Women with BED were significantly more likely to report current or lifetime affective and anxiety disorders as well as family histories of BED. Family histories of substance abuse did not differ across groups. Significantly more women with BED rated their parents' parenting style as consistent with “affectionless control” on the Parental Bonding Instrument, and reported significantly lower cohesion, expressiveness, conflict, independence, intellectual-cultural orientation, and active-recreational orientation on the Family Environment Scale.

Uncontrolled eating is associated with reduced executive functioning

Accumulating evidence indicates obesity is associated with reduced cognitive functioning, particularly attention and executive function, as well as maladaptive eating behaviour such as uncontrolled eating. The current study examined relationships between eating patterns and attention/executive function test performance in lean and obese individuals. Sixty-two (32 lean, 30 obese) healthy young adults (21.13 ± 2.31 years; 56.5% female) completed the abbreviated Three-Factor Eating Questionnaire (TFEQ-R18) to assess eating patterns, including uncontrolled eating, cognitive restraint, and emotional eating. The Go/No-Go (GNG), Running Memory Continuous Performance Test (RCMPT) and Standard Continuous Performance Test from the Automated Neuropsychological Assessment Metrics-4 were administered as measures of executive functioning and attention. An independent samples t-test revealed greater report of uncontrolled eating in obese compared with lean participants (t[60] = -2.174, P < 0.05; d = -0.55) but no differences in cognitive restraint or emotional eating. Multivariate analysis of variance revealed cognitive differences between lean and obese groups (F[6, 54] = 3.86, P < 0.005; λ = 0.70; ηp(2) = 0.30), which were driven by GNG reaction time (F[1, 59] = 8.36, P < 0.01, d = 0.74). Pearson bivariate correlations revealed a positive correlation between uncontrolled eating and reaction time on GNG (r = 0.343, P < 0.05) and RMCPT (r = 0.267, P < 0.05) in all participants. Relative to lean participants, obese individuals reported higher levels of uncontrolled eating and exhibited slower performance on a task of inhibitory control. In the full sample, greater self-reported dyscontrol in eating behaviour was related to slower inhibitory control and working memory. Results support a link between executive function and control of eating behaviour. Obese individuals may be more vulnerable to difficulties in these domains relative to those who are lean.

A mindful eating group intervention for obese women: a mixed methods feasibility study

The purpose of this mixed methods study was to: 1) describe the effect of an 8-week mindful eating intervention on mindful eating, weight loss self-efficacy, depression, and biomarkers of weight in urban, underserved, obese women; and 2) identify themes of the lived experience of mindful eating. A convenience sample of 12 obese women was recruited with data collected at baseline and 8 weeks followed by a focus group. Only self-efficacy for weight loss significantly increased over 8 weeks (t=-2.63, P=.04). Qualitative findings of mindful eating supported quantitative findings and extended understanding about the effect of the intervention.

Binge Eating Disorder: Current Knowledge and Future Directions

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.

Alexithymia and suicide ideation in a sample of patients with binge eating disorder

OBJECTIVE

The goal of this cross-sectional study was to evaluate the relationships between alexithymia and suicide ideation in 80 adult outpatients with a DSM-IV diagnosis of binge eating disorder (BED).

METHODS

Alexithymia was measured with the 20-item Toronto Alexithymia Scale (TAS-20); suicide ideation was assessed with the Scale of Suicide Ideation (SSI); severity of BED was assessed with the Binge Eating Scale (BES); and depressive and anxiety symptoms were evaluated, respectively, with the Montgomery-Åsberg Depression Rating Scale (MADRS) and the Hamilton Anxiety Rating Scale (Ham-A).

RESULTS

Prevalence of current suicide ideation was 27.5% (n = 22) in this sample and 10 subjects (12.5%) had attempted suicide at some time in their lives. Subjects with alexithymia had more significant suicide ideation, a higher prevalence of current suicide ideation, and more previous suicide attempts than those without alexithymia. In a linear regression model, higher MADRS scores and higher scores on the Difficulty in Identifying Feelings/Difficulty in Describing Feelings dimensions of the TAS-20 were associated with increased suicide ideation.

DISCUSSION

Suicidal behavior is no less common in BED than in other eating disorders. Individuals with BED may show increased suicide ideation, especially in the presence of alexithymia and depressive symptoms, even if these symptoms are subclinical. The authors also discuss limitations of this study and future research needs.

Binge Eating Disorder and body image perception among university students

Binge Eating Disorder (BED) is characterized by recurrent episodes of compulsive eating, without any compensatory behavior to avoid possible gain weight. Individuals who suffer from eating disorders often show negative self-image. The present paper aimed to assess BED prevalence and self-image disorders among university students in the city of São José do Rio Preto, State of São Paulo, Brazil. The survey had the participation of 217 undergraduates. The following procedures were carried out: a personal data questionnaire, the Binge Eating Scale and a figure scale. In the surveyed population, 12.90% showed BED. Most subjects (86.32%) chose larger figures when compared to their current BMI, overestimating their body size. Furthermore, BED individuals showed higher self-image inadequacy in comparison to people without the disorder. Therefore, this is a public health problem to which undergraduates are exposed; forthcoming studies may be carried out to understand BED and associated commorbidities.

A 24-week randomised controlled trial comparing usual care and metabolic-based diet plans in obese adults

BACKGROUND

Usual care (UC) practice for weight management often includes providing standardised, ad libitum, low-calorie nutrition plans. However, weight loss using such plans appears comparable with metabolic-based diet (MD) plans that are closer to resting energy expenditure (REE) level. In addition, MD plans are approximately 250-750 kcal/day higher in caloric values compared with UC plans. Therefore, the purpose of this study was to compare weight loss and eating behaviour differences between UC and MD plans.

METHODS

Seventy-four obese (30.0-51.7 kg/m(2) ) adults (21-67 years) voluntarily participated in a 24-week randomised study. UC men and women received a fixed, ad libitum, 1600 and 1200 kcal/day nutrient plan, respectively. MD participants received an individualised treatment plan based from measured REE. Bodyweight and eating behaviours (i.e. intake, restraint and uncontrolled eating) were assessed over time.

RESULTS

Intent-to-treat analysis indicated no significant difference in weight loss (UC: -5.7 ± 6.3% vs. MD: -5.3 ± 7.1% p = 0.67) between groups over time. There was no difference in daily energy intake (UC: 2490 ± 576 kcal/day vs. MD: 2525 ± 475 kcal/day) at 24 weeks between groups. Both groups experienced a significant improvement (p < 0.05) in eating dietary restraint and uncontrolled eating yet there was no difference between groups.

CONCLUSION

From this study, UC calorie plans do not generate more weight loss or improve eating behaviours in comparison with MD calorie plans. As treatment effects are comparable, clinicians can select UC or MD plan options based on clinician and patient preference.

Overeating Behavior and Striatal Dopamine with 6-[F]-Fluoro-L-m-Tyrosine PET

Eating behavior may be affected by dopamine synthesis capacity. In this study, 6-[(18)F]-fluoro-L-m-tyrosine (FMT) positron emission tomography (PET) uptake in striatal subregions was correlated with BMI (kg/m(2)) and an estimate of the frequency of prior weight loss attempts in 15 healthy subjects. BMI was negatively correlated with FMT uptake in the dorsal caudate. Although the association between BMI and FMT uptake in the dorsal caudate was not significant upon correction for age and sex, the association fell within the range of a statistical trend. Weight loss attempts divided by years trying was also negatively correlated with FMT uptake in the dorsal putamen (P = .05). These results suggest an association between low dorsal striatal presynaptic dopamine synthesis capacity and overeating behavior.

Self-reported history of overweight and its relationship to disordered eating in adolescent girls with Type 1 diabetes

AIMS

Increased body weight and disordered eating attitudes/behaviours are common in adolescent girls with Type 1 diabetes (T1D). Disordered eating increases risks for diabetes-related complications. This study aimed to identify a rapid screening approach for disordered eating attitudes and behaviours in adolescent girls with T1D and to examine the relationship between disordered eating and body weight in this population.

METHODS

Ninety adolescent girls, aged 12-19 years, provided a self-assessment of weight status. Participants also completed questionnaires to assess attitudes/behaviours toward food and eating, appetitive responsiveness to the food environment, disinhibition in eating and weight history.

RESULTS

Forty-three per cent of participants reported a history of overweight. Compared with participants who reported never being overweight, those who reported ever being overweight were significantly older, scored significantly higher on all measures of disordered eating attitudes/behaviours (P < or = 0.009) and were 4.8 times more likely to be currently overweight or obese (P < 0.001). Glycated haemoglobin (HbA(1c)) was similar between those who did and did not report ever being overweight.

CONCLUSIONS

Because of the ill-health effects of disordered eating and the higher rate of overweight in adolescent girls with T1D, effective screening tools are warranted. The single question 'Have you ever been overweight?' may be sufficient as a first question to screen for those at high risk for disordered eating attitudes/behaviours and to provide early intervention and prevention.

Asymmetric prefrontal cortex activation in relation to markers of overeating in obese humans

Dietary restraint is heavily influenced by affect, which has been independently related to asymmetrical activation in the prefrontal cortex (prefrontal asymmetry) in electroencephalograph (EEG) studies. In normal weight individuals, dietary restraint has been related to prefrontal asymmetry; however, this relationship was not mediated by affect. This study was designed to test the hypotheses that, in an overweight and obese sample, dietary restraint as well as binge eating, disinhibition, hunger, and appetitive responsivity would be related to prefrontal asymmetry independent of affect at the time of assessment. Resting EEG recordings and self-report measures of overeating and affect were collected in 28 overweight and obese adults. Linear regression analyses were used to predict prefrontal asymmetry from appetitive measures while controlling for affect. Cognitive restraint and binge eating were not associated with prefrontal asymmetry. However, disinhibition, hunger, and appetitive responsivity predicted left-, greater than right-, sided prefrontal cortex activation independent of affect. Findings in this study add to a growing literature implicating the prefrontal cortex in the cognitive control of dietary intake. Further research to specify the precise role of prefrontal asymmetry in the motivation toward, and cessation of, feeding in obese individuals is encouraged.

Associations among binge eating behavior patterns and gastrointestinal symptoms: a population-based study

BACKGROUND

The psychological symptoms associated with binge eating disorder (BED) have been well documented. However, the physical symptoms associated with BED have not been explored. Gastrointestinal (GI) symptoms such as heartburn and diarrhea are more prevalent in obese adults, but the associations remain unexplained. Patients with bulimia have increased gastric capacity. The objective of the study was to examine if the severity of binge eating episodes would be associated with upper and lower GI symptoms.

METHODS

Population-based survey of community residents through a mailed questionnaire measuring GI symptoms, frequency of binge eating episodes and physical activity level. The association of GI symptoms with frequency of binge eating episodes was assessed using logistic regression models adjusting for age, gender, body mass index (BMI) and physical activity level.

RESULTS

In 4096 subjects, BED was present in 6.1%. After adjusting for BMI, age, gender, race, diabetes mellitus, socioeconomic status and physical activity level, BED was independently associated with the following upper GI symptoms: acid regurgitation (P<0.001), heartburn (P<0.001), dysphagia (P<0.001), bloating (P<0.001) and upper abdominal pain (P<0.001). BED was also associated with the following lower GI symptoms: diarrhea (P<0.001), urgency (P<0.001), constipation (P<0.01) and feeling of anal blockage (P=0.001).

CONCLUSION

BED appears to be associated with the experience of both upper and lower GI symptoms in the general population, independent of the level of obesity. The relationship between increased GI symptoms and physiological responses to increased volume and calorie loads, nutritional selections and rapidity of food ingestion in individuals with BED deserves further study.

The contributions of weight problem perception, BMI, gender, mood, and smoking status to binge eating among college students

College student participants (N=1063; 77.8% response rate) completed a web-based survey assessing demographics, depression, anxiety, body image, cigarette smoking, and weight history. Among overweight participants, 42.6% of those who believed they were overweight admitted to binge eating, while only 30.1% who did not feel overweight did so (p<.05). Among non-overweight participants, 43.2% of those who believed they were overweight admitted to binge eating, while only 32.9% of those who did not feel overweight did so (p<.05). Weight Problem Perception (WPP) mediated the contribution of BMI on binge eating outcomes, and WPP contributed significantly to the prediction of binge eating, beyond the risk conferred by established correlates of binge eating (e.g., gender, mood, and cigarette smoking). Results suggest that when assessing risk for binge eating, a one-question assessment of whether or not an individual believes s/he is overweight has significant predictive power. Findings are consistent with literature on the importance of the "fat self-schema" [Stein, K.F., & Corte, C. (2007). Identity impairment and the eating disorders: Content and organization of the self-concept in women with anorexia nervosa and bulimia nervosa. European Eating Disorders Review, 15 (1), 58-69] in disordered eating and theory implicating identity in the maintenance of addictive behavior [West, R.W. (2006). Theory of Addiction.

Relevance of animal models to human eating disorders and obesity

BACKGROUND AND RATIONALE

This review addresses the role animal models play in contributing to our knowledge about the eating disorders anorexia nervosa (AN) and bulimia nervosa (BN) and obesity.

OBJECTIVES

Explore the usefulness of animal models in complex biobehavioral familial conditions, such as AN, BN, and obesity, that involve interactions among genetic, physiologic, psychological, and cultural factors.

RESULTS AND CONCLUSIONS

The most promising animal model to mimic AN is the activity-based anorexia rodent model leading to pathological weight loss. The paradigm incorporates reward elements of the drive for activity in the presence of an appetite and allows the use of genetically modified animals. For BN, the sham-feeding preparation in rodents equipped with a gastric fistula appears to be best suited to reproduce the postprandial emesis and the defects in satiety. Animal models that incorporate genes linked to behavior and mood may clarify biobehavioral processes underlying AN and BN. By contrast, a relative abundance of animal models has contributed to our understanding of human obesity. Both environmental and genetic determinants of obesity have been modeled in rodents. Here, we consider single gene mutant obesity models, along with models of obesigenic environmental conditions. The contributions of animal models to obesity research are illustrated by their utility for identifying genes linked to human obesity, for elucidating the pathways that regulate body weight and for the identification of potential therapeutic targets. The utility of these models may be further improved by exploring the impact of experimental manipulations on the behavioral determinants of energy balance.

Sex differences in the relation of weight loss self-efficacy, binge eating, and depressive symptoms to weight loss success in a residential obesity treatment program

The aim of the current study was to examine whether weight loss self-efficacy, binge eating, and depressive symptoms predicted weight loss during treatment, and whether gender moderates these associations with prospective data from 297 participants (223 women and 74 men) enrolled in a residential obesity treatment program. Men reported higher initial levels of self-efficacy than women, whereas women reported greater pre-treatment levels of binge eating and depressive symptoms. Higher pre-treatment levels of weight control self-efficacy, binge eating, and depressive symptoms predicted greater weight loss in men, but not in women. Results suggest that certain psychological and behavioral factors should be considered when implementing weight loss interventions, and indicate a need to consider gender differences in predictors of weight loss treatment. Future research should seek to identify predictors of weight loss among 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/m(2)) 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 < or = 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.

Cognitive-Behavioural Treatment For Women Who Binge Eat

Purpose: A dietitian-administered, shortened form of the Apple and Agras cognitive-behavioural therapy (CBT) method was evaluated in a group setting to determine its effect on improving obese women's self-esteem and reducing binge-eating behaviours, depression, and negative body image.

Methods: Participants were recruited through newspaper and radio advertisements. Respondents who met study selection criteria were randomly assigned to either a CBT group (n=13) or a delayed group (D-CBT) (n=9). The treatment was administered over six weekly sessions to the CBT group, and then twice weekly over three weeks to the D-CBT group. Two measures of bingeing behaviour (severity and frequency), three measures of mood (depression, body image, and self-esteem), and body weight were assessed.

Results: The intervention did not result in any changes in body weight. There were statistically significant and clinically important changes after treatment (p<0.05) for all five measures. Binge-eating severity and frequency decreased, depression decreased, body image improved, and self-esteem improved. All changes were greater in the six-week treatment group.

Conclusions: The dietitian-administered, group setting CBT program is effective for reducing binge eating and improving emotional state in obese women.

Recurrent binge eating (RBE) and its characteristics in a sample of young women in Germany

OBJECTIVE

To examine the characteristics of recurrent binge eating (RBE) in a non-treatment-seeking sample from the general population. RBE individuals are described in terms of socio-economic status, general psychopathology, and comorbidity rates of mental disorders.

METHOD

Participants were 1877 German females aged 18-24 years from a population-based epidemiological study.

RESULTS/DISCUSSION

The point prevalence of RBE in our sample was 0.9% (N = 17). Compared to healthy women, subjects with RBE suffered more often from comorbid mental disorders and also exhibited more general psychopathology: They were similar to women with other mental disorders and other eating disorders (EDs). RBE seems to be a syndrome of clinical significance itself and might be an important risk factor for the development of further EDs, especially binge eating disorder (BED) and other mental disorders.

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 > or = 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.

The relationships among trauma, stress, ethnicity, and binge eating

The present study investigated whether trauma, stress, and discriminatory experiences influenced binge eating among 93 African American and 85 Caucasian women. Trauma and stress were significantly related to binge eating for both groups, although the stress- binge eating relationship was stronger for Caucasian women. Ethnicity did not moderate the relationship between trauma and binge eating, but did moderate the stress-binge eating relationship. Finally, the hypothesis that trauma and stress would influence binge eating through their effects on function of eating was partially supported; the relationship between stress and binge eating was partially mediated by function of eating among Caucasian women. The implications of these findings for our understanding of binge eating are discussed.

Obesity and household food insecurity: evidence from a sample of rural households in Malaysia

OBJECTIVE

The study examined nutritional outcomes related to body fat accumulation of food insecurity among women from selected rural communities in Malaysia.

DESIGN

Cross-sectional study.

SETTING

Rural communities (seven villages and two palm plantations) in a district with high percentage of welfare recipients.

SUBJECTS AND MEASUREMENTS

Malay (n = 140) and Indian (n = 60) women were interviewed and measured for demographic, socioeconomic, anthropometric, dietary and physical activity information. The women were measured for their body mass index and waist circumference (WC). Energy and nutrient intakes, food group intake and food variety score were analyzed from 24 h dietary recalls and food-frequency questionnaire. Daily physical activity of the women was examined as the number of hours spent in economic, domestic, leisure and sport activities.

RESULTS

Using the Radimer/Cornell Hunger and Food Insecurity Instrument, 58% of the women reported some degree of food insecurity (household insecure 14%, adult insecure 9.5% and child hunger 34.5%). In general, food-insecure women had lower years of education, household income and income per capita, more children and mothers as housewives. More than 50% of food-insecure women were overweight and obese than women from food-secure households (38%). Similarly, more food-insecure women (32-47%) had at-risk WC (> or = 88 cm) than food-secure women (29%). Food-insecure women spent significantly more time in domestic and leisure activities than food-secure women. Overweight and abdominal adiposity among the women were associated with a number of independent variables, such as women as housewives, women with more children, larger household size, food insecurity, shorter time spent in economic activities, longer time spent in leisure activities and lower food variety score. After adjusting for factors that are related to both adiposity and food insecurity, women from food-insecure households were significantly more likely to have at-risk WC, but not obese.

CONCLUSION

Among this sample of rural women, the relationship between food insecurity and obesity is a complex one, which involves the interaction with other factors. Nevertheless, given that obesity and food insecurity are of public health concerns in the developing nations, the association between the two should be further investigated.
