OBJECTIVES: To refine the biobehavioral markers of binge eating disorder (BED). METHODS: We conducted fMRI brain scans using images of high energy processed food (HEPF), low energy unprocessed food (LEUF), or non-foods (NF) in 42 adults (obese with BED [obese -BED; n=13] and obese with no BED [obese non-BED; n=29]) selected via ads. Two blood oxygenated level dependent (BOLD) signal contrast maps were examined: food versus nonfood, and HEPF versus LEUF. In addition, score differences on the disinhibition scale were correlated with BOLD signals...

Eating disorders are associated with both negative and positive emotional reactions towards food. Individual eating disorder symptoms may relate to distinct emotional responses to food, which could necessitate tailored treatments based on symptom presentation. We examined associations between eating disorder symptoms and psychophysiological responses to food versus neutral images in 87 college students [mean (SD) age = 19.70 (2.09); mean (SD) body mass index = 23.25(2.77)]. Reflexive and facial electromyography measures tapping negative emotional reactivity (startle blink reflex) and appraisal (corrugator muscle response) as well as positive emotional reactivity (postauricular reflex) and appraisal (zygomaticus muscle response) were collected...

Emotion regulation appears to play a key role in eating disorders. However, prior attempts to associate specific emotion regulation abilities with specific types of eating disorders resulted in inconsistent findings. Moreover, far less is known about emotion regulation in eating disorders during adolescence, a critical period of emotional development. The current study addresses this gap, comparing emotion regulation characteristics between adolescents with restrictive types of eating disorders and those with binge eating or purging types of eating disorders...

Similar symptomatology manifestations and high co-morbidity in substance and non-substance addictions suggest that there may be a common pathogenesis between them. Associated with impulse control and emotional processing, the monoamine neurotransmitter system genes are suggested to be related to both substance and non-substance addictions, such as dopamine (DA) system, 5-hydroxytryptamine/serotonin (5-HT) system, the endogenous opioid system and so on. Here we reviewed the similarities and differences in genetics between classic substance addiction and common types of non-substance addiction, e...

BACKGROUND: The current investigation aims to predict 3-year postoperative percent total weight loss among a sample of bariatric surgery patients with super-super obesity. OBJECTIVE: Previous research implies that persons with presurgical super-super obesity (body mass index [BMI] ≥60 kg/m(2)) tend to have poorer loss outcomes compared with those with a lower presurgical BMI after bariatric surgery. SETTING: Cleveland Clinic, Bariatric & Metabolic Institute, Cleveland, OH...

Evidence points to eating disorder patients displaying altered rates of delay discounting (one's degree of preference for immediate rewards over larger delayed rewards). Anorexia nervosa (AN) patients are believed to have an increased capacity to delay reward, which reflects their ability to override the drive to eat. Contrarily, binge eating disorder (BED) patients are associated with a reduced predisposition to delay gratification. Here, we investigated monetary delay discounting and impulsivity in 80 adult women with EDs (56 AN and 24 BED), diagnosed according to Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition criteria, and 80 healthy controls...

OBJECTIVE: The emotion regulation (ER) model of binge eating posits that individuals with binge-eating disorder (BED) experience more intense emotions and greater difficulties in ER than individuals without BED, leading them to binge eat as a means of regulating emotions. According to this model, individuals with BED should report greater difficulties in ER than their non-BED counterparts, the severity of these difficulties should be positively associated with BED symptoms, and this association should be stronger when individuals experience persistent negative emotions (i...

The role of emotional functioning in the development and maintenance of obesity has been investigated, but the literature is poorly integrated. A systematic review and meta-analysis was performed to explore emotional processing impairments in obesity. PubMed, Web of Knowledge and PsycINFO databases were searched in March 2016, yielding 31 studies comparing emotional processing competencies in individuals with obesity, with or without binge eating disorder (BED), and control groups. Meta-analyses demonstrated that individuals with obesity had higher scores of alexithymia (d = 0...

OBJECTIVE: Child maltreatment is associated with an increased likelihood of having mood disorders, anxiety disorders, post-traumatic stress disorder, substance use disorders, and personality disorders, but far less is known about eating disorders. The objective of the current study was to examine the associations between child maltreatment, including harsh physical punishment, physical abuse, sexual abuse, emotional abuse, emotional neglect, physical neglect, and exposure to intimate partner violence, and eating disorders in adulthood among men and women...

While existing treatments produce remission in a relatively large percentage of individuals with binge eating disorder (BED), room for improvement remains. Interventions designed to increase emotion regulation skills and clarify one's chosen values may be well-suited to address factors known to maintain BED. The current study examined the preliminary efficacy of a group-based treatment, Acceptance-based Behavioral Therapy (ABBT), in a small open trial (n=19), as well as the relationship between changes in hypothesized mechanisms of action and outcomes...

Although there is preliminary evidence that inhibitory control training improves impulsive eating, less is known about the effects on eating behaviour and weight loss in clinical samples. Sixty-nine treatment-seeking adults with obesity (binge-eating disorder 33.3%; other specific feeding and eating disorders 40.6%) were randomly blockwise allocated to ImpulsE, an intervention to improve inhibitory control and emotion regulation abilities or a guideline-appropriate cognitive behavioural therapy (CBT)-based treatment as usual...

BACKGROUND: Recent research, especially from the USA, suggests that comorbid binge eating (BE) behaviour and BE disorder are frequent in individuals with Bipolar Disorder (BD). Although basic clinical associations between BD and BE have been investigated, less is known about psychological or temperamental dimensions and qualitative aspects of eating habits. In a French cohort of patients with BD, we investigated the prevalence of BE behaviour and any associations with illness characteristics, anxiety, impulsivity, emotional regulation and eating habits...

OBJECTIVE: Rapid and substantial behavior change (RSBC) early in cognitive behavior therapy (CBT) for eating disorders is the strongest known predictor of treatment outcome. Rapid change in other clinically relevant variables may also be important. This study examined whether rapid change in emotion regulation predicted treatment outcomes, beyond the effects of RSBC. METHOD: Participants were diagnosed with bulimia nervosa or purging disorder (N = 104) and completed ≥6 weeks of CBT-based intensive treatment...

Existing research suggests that there is an overlap between binge eating disorder (BED) and the construct of 'food addiction' (FA). The objective of this study was to determine the overlapping features of BED and FA through a comparison of the individual scales of commonly used tools including the Binge Eating Scale (BES) and the Yale Food Addiction Scale (YFAS) in a sample of Australian adults. Adults (>18 years of age) were invited to complete an anonymous online survey on FA. Binge eating was assessed through the BES and addictive eating behaviours were assessed through the YFAS (n = 1344)...

Patients with an eating disorder have difficulties perceiving emotions. They have skills deficits in the acceptance, modification and opposite action to emotion driven behavior. They use disturbed eating behavior (restrained eating, binge eating and purging), but also situational avoidance, dissociation and substance use as an instrument for emotional avoidance. This constitutes an innovative starting point for therapy.

Eating-disorders (EDs) consequences to human health are devastating, involving social, mental, emotional, physical and life-threatening aspects, concluding on impairment and death in cases of extreme anorexia nervosa. It also implies that people suffering an ED need to find psychiatric and psychological help as soon as possible to achieve a fully physical and emotional recovery. Unfortunately, to date, there is a crucial lack of efficient clinical treatment to these disorders. In this review, we present an overview concerning the actual pharmacological and psychological treatments, the knowledge of cells, circuits, neuropeptides, neuromodulators and hormones in the human brain- and other organs- underlying these disorders, the studies in animal models and, finally, the genetic approaches devoted to face this challenge...

OBJECTIVE: Preadolescent loss-of-control-eating (LOC-eating) is a risk factor for excess weight gain and binge-eating-disorder. We evaluated feasibility and acceptability of a preventive family-based interpersonal psychotherapy (FB-IPT) program. FB-IPT was compared to family-based health education (FB-HE) to evaluate changes in children's psychosocial functioning, LOC-eating, and body mass. METHOD: A randomized, controlled pilot trial was conducted with 29 children, 8 to 13 years who had overweight/obesity and LOC-eating...

The obesity rate is higher among veterans than the general population, yet few studies have examined their eating behaviors, and none have examined the presence of night eating and related comorbidities. This study examines night eating syndrome (NES) among veterans seeking weight management treatment, and relationships between NES and weight, insomnia, disordered eating, and psychological variables. The sample consisted of 110 veterans referred to a weight management program at VA Connecticut Healthcare System...
