obesity, binge eating

Jaime A Coffino, Natalia C Orloff, Julia M Hormes
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)...

The Yale Food Addiction Scale (YFAS) measures addiction-like eating of palatable foods based on the seven diagnostic criteria for substance dependence in the fourth revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). Most recently, a new version of the YFAS has been developed based on the revised eleven diagnostic criteria for substance use disorder in DSM-5. This YFAS 2.0 was translated into German and used among other measures in a study with 455 university students (89% female) and in a study with 138 obese patients presenting for bariatric surgery (78% female)...

Compulsive, binge eating of highly palatable food constitutes a core feature of some forms of obesity and eating disorders, as well as of the recently proposed disorder of food addiction. Trace Amine-Associated Receptor 1 (TAAR1) is a highly conserved G-protein-coupled receptor bound by endogenous trace amines. TAAR1 agonists have been shown to reduce multiple behavioral effects of drugs of abuse through their actions on the mesocorticolimbic system. In this study, we hypothesized that TAAR1 may play a role in compulsive, binge-like eating; we tested this hypothesis by assessing the effects of a TAAR1 agonist, RO5256390, in multiple excessive feeding-related behaviors induced by limiting access to a highly palatable diet in rats...

The aim of this study was to conduct a comprehensive quantitative synthesis of the effects of mindfulness training interventions on weight-loss and health behaviours in adults with overweight and obesity using meta-analytic techniques. Studies included in the analysis (k=12) were randomised controlled trials investigating the effects of any form of mindfulness training on weight loss, impulsive eating, binge eating, or physical activity participation in adults with overweight and obesity. Random effects meta-analysis revealed that mindfulness training had no significant effect on weight loss, but an overall negative effect on impulsive eating (d=-1...

The central-nervous-system and viscera constitute a functional ensemble, the gut-brain axis, that allows bidirectional information flow that contributes to the control of feeding-behaviour based not only on the homeostatic, but also on the hedonic aspects of food-intake. The prevalence of eating disorders, such as anorexia nervosa, binge eating and obesity, poses an enormous clinical burden, and involves an ever-growing percentage of the population worldwide. Clinical and preclinical research is constantly adding new information to the field and orienting further studies with the aim of providing a foundation for developing more specific and effective treatment approaches to pathological conditions...

OBJECTIVE: To evaluate associations between binge-eating disorder (BED) and somatic illnesses and determine whether medical comorbidities are more common in individuals who present with BED and comorbid obesity. METHOD: Cases (n = 850) were individuals with a BED diagnosis in the Swedish eating disorders quality registers. Ten community controls were matched to each case on sex, and year, month, and county of birth. Associations of BED status with neurologic, immune, respiratory, gastrointestinal, skin, musculoskeletal, genitourinary, circulatory, and endocrine system diseases were evaluated using conditional logistic regression models...

The objective of this study was to examine the relationship between overvaluation of weight/shape ('overvaluation') and emotion regulation (ER) difficulties among women with binge eating disorder (BED) symptoms. Four groups of women were recruited from a community-based sample and compared on ER difficulties: individuals with probable BED with (n=102) and without (n=72) overvaluation, and non-binge eating obese (n=40) and healthy-weight (n=40) control participants. Data for patients with a formal diagnosis of BED receiving treatment from a previous study were included for numerical comparative purposes...

OBJECTIVE: A previous study reported that preoperative binge-eating disorder (BED) did not attenuate weight loss at 12 months after bariatric surgery. This report extends the authors' prior study by examining weight loss at 24 months. METHODS: A modified intention-to-treat population was used to compare 24-month changes in weight among 59 participants treated with bariatric surgery, determined preoperatively to be free of a current eating disorder, with changes in 33 surgically treated participants with BED...

INTRODUCTION: Interleukin-7 (IL-7) is a cytokine involved in energy homeostasis as demonstrated in rodents. Anorexia nervosa is characterized by restrained eating behavior despite adaptive orexigenic regulation profile including high ghrelin plasma levels. Constitutional thinness is a physiological condition of resistance to weight gain with physiological anorexigenic profile including high Peptide YY plasma level. Healthy obesity can be considered as a physiological state of resistance to weight loss with opposite appetite regulating profile to constitutional thinness including low Peptide YY plasma level...

While pituitary adenylate cyclase activating polypeptide (PACAP) signaling in the hypothalamic ventromedial nuclei (VMN) has been shown to regulate feeding, a challenge in unmasking a role for this peptide in obesity is that excess feeding can involve numerous mechanisms including homeostatic (hunger) and hedonic-related (palatability) drives. In these studies, we first isolated distinct feeding drives by developing a novel model of binge behavior in which homeostatic-driven feeding was temporally separated from feeding driven by food palatability...

Multiple measures of impulsivity predict both obesity and binge-eating disorder; however, those who binge-eat represent a behaviorally distinct subset of all overweight individuals. In the current experiment, 10 male Wistar rats completed three conditions in counterbalanced order: (a) impulsivity assessed with a delay discounting task; (b) binge-eating measured by consumption of intermittently available Oreo cookies; and (c) diet-induced obesity proneness measured by weight gain when provided with a sweet high-fat diet ad libitum for 2 consecutive weeks...

BACKGROUND: Extreme obesity in adolescents is considered largely resistant to therapy. The aim of this study was to demonstrate the short- and long-term BMI histories of patients who have successfully participated in an inpatient weight loss program, and to look for factors influencing the very good success. METHODS: For the case series 10 youths were selected, who participated in an inpatient weight reduction program for 6-12 months and who succeeded in reducing BMI for the short and for the long term...

PURPOSE: To gain further understanding of the general medical comorbidity of binge eating disorder (BED) beyond its association with obesity. METHOD: We reviewed studies of general medical comorbidity in people with BED or clinically significant binge eating behavior beyond obesity. We also reviewed studies of BED in specific medical conditions. RESULTS: Three broad study categories of medical comorbidity in BED were found: cross-sectional studies of medical conditions in BED; prospective studies of medical conditions in BED; and studies of BED in specific medical conditions...

Behavioral adaptation is required for the successful navigation of a constantly changing environment. Impairments in behavioral flexibility are commonly observed in psychiatric disorders including those of addiction. This study investigates two distinct facets of compulsivity, namely reversal learning and attentional set shifting, implicating orbitofrontal and lateral prefrontal regions respectively, across disorders of primary and secondary rewards. Obese subjects with and without binge eating disorder (BED), individuals with compulsive sexual behaviors (CSB), alcohol dependence (AD) and pathological video-gaming (VG) were tested with two computerized tasks: the probabilistic reversal task (trials to criterion and win-stay/lose-shift errors) and the intra/extra-dimensional set shift task (IED)...

OBJECTIVE: To examine the associations among self-reported loss-of-control (LOC) eating, emotion dysregulation, body mass, and objective energy intake among youth. Emotion dysregulation may be 1 individual factor that promotes excess energy intake and increases in body mass among youth with LOC eating. METHOD: Children and adolescents (N = 230; 8 to 17 years) enrolled in a nonintervention study completed a structured interview to determine the presence or absence of self-reported LOC eating...

Obesity and binge eating disorder (BED) are both associated with deficiencies in executive function. The Behaviour Rating Inventory of Executive Function - Adult Version (BRIEF-A) is a self-report measure that assesses executive function. This study aimed to examine the psychometric properties of the BRIEF-A in an obese population, with and without BED, and to explore the differences on the BRIEF-A in the obese, with and without BED, compared to normative sample. 98 obese participants (70 BED) completed the BRIEF-A, DASS-21 and several performance-based measures of executive function...

Binge eating is a significant problem in both eating disordered and community populations alike. Extensive support exists for the dual pathway model of binge eating in both adolescent and adult clinical and nonclinical populations. However, the restrained eating pathway to binge eating in particular has failed to be confirmed in some studies. In particular, the dual pathway model may not be applicable to overweight binge eaters. The current study examined the applicability of the dual pathway model in a sample of healthy and overweight binge eaters...
