Xiaobing Zhang, Anthony N van den Pol
The neuronal substrate for binge eating, which can at times lead to obesity, is not clear. We find that optogenetic stimulation of mouse zona incerta (ZI) γ-aminobutyric acid (GABA) neurons or their axonal projections to paraventricular thalamus (PVT) excitatory neurons immediately (in 2 to 3 seconds) evoked binge-like eating. Minimal intermittent stimulation led to body weight gain; ZI GABA neuron ablation reduced weight. ZI stimulation generated 35% of normal 24-hour food intake in just 10 minutes. The ZI cells were excited by food deprivation and the gut hunger signal ghrelin...

OBJECTIVE: There are strong associations among trauma and eating disorders. However, while trauma and eating disorders are more common among veterans than other populations, there is little information on how military-specific stressors affect eating disorder risk. This study's objective was to determine whether military sexual trauma and combat exposure were independent predictors of eating disorders among women veterans, a high-risk group. METHOD: Participants were women age 18-70, using VA medical center services, without psychotic disorders or suicidal ideation (N = 407)...

While there is good evidence that binge eating disorder (BED) is linked to higher-than-expected use of a broad range of addictive behaviors, mechanisms underlying this association are not well understood. Using a mediation-analytical approach with three age- and gender-matched groups - overweight/obese adults with (n = 42) and without (n = 104) BED, and normal-weight control participants (n = 73) - we tested the hypothesis that adults with BED would engage in more addictive behaviors and have higher scores on a personality-risk index than the two control groups...

Obesity-associated comorbidities greatly impact the quality and expectancy of life. Binge eating disorder (BED) is the most prevalent eating disorder and it is an important risk factor for obesity and metabolic syndrome (MetS). For these reasons, we aimed to assess the effect of an interdisciplinary therapy on the symptoms of BED and the prevalence of MetS in obese adults. It was hypothesized that the interdisciplinary therapy would decrease symptoms of BED and markers of MetS. Twenty-four volunteers (BMI 34...

OBJECTIVE: Most weight loss research focuses on weight as the primary outcome, often to the exclusion of other physiological or psychological measures. This study aims to provide a holistic evaluation of the effects from weight loss interventions for individuals with obesity by examining the physiological, psychological and eating disorders outcomes from these interventions. METHODS: Databases Medline, PsycInfo and Cochrane Library (2011-2016) were searched for randomised controlled trials and systematic reviews of obesity treatments (dietary, exercise, behavioural, psychological, pharmacological or surgical)...

Binge eating disorder (BED) is characterized by recurrent overeating episodes, accompanied by loss of control (LOC), in the absence of compensatory behaviors. The literature supports that men overeat as often or more often than do women, but they are less likely to endorse LOC and other BED symptoms. Thus, rates of BED are lower among men. However, differences in prevalence rates may reflect gender bias in current conceptualizations of eating disorders and BED diagnostic criteria, not necessarily truly lower rates of disordered eating among men...

PURPOSE: To analyse the short-term effectiveness of an intensive multidimensional inpatient programme specifically developed for patients with severe obesity. METHODS: A multidisciplinary team managed a 3-week residential programme characterised by the integration of nutritional and physical rehabilitation with psychological and educational intervention. All patients consecutively admitted in 10 months were analysed at admission and discharge for changes in the following domains: anthropometry (weight, body mass index (BMI), waist and neck circumferences), cardiovascular risk factors (glycaemia, HbA1c, lipid profile, blood pressure), quality of life, eating behaviour, and physical performance (VO2peak by incremental cycle ergometer test, 6-min walking test (6MWT), chair stands test)...

Weight-based teasing is common among youth, but little is known about its long-term impact on health outcomes. We aimed to 1) identify whether weight-based teasing in adolescence predicts adverse eating and weight-related outcomes 15years later; and 2) determine whether teasing source (peers or family) affects these outcomes. Data were collected from Project EAT-IV (Eating and Activity in Teens and Young Adults) (N=1830), a longitudinal cohort study that followed a diverse sample of adolescents from 1999 (baseline) to 2015 (follow-up)...

PURPOSE OF REVIEW: The objective of this paper is to review the role that hedonic factors, emotions and self-regulation systems have over eating behaviours from animal models to humans. RECENT FINDINGS: Evidence has been found to suggest that for some high-risk individuals, obesity/binge eating may develop as an impulsive reaction to negative emotions that over time becomes a compulsive habit. Animal models highlight the neural mechanisms that might underlie this process and suggest similarities with substance use disorders...

BACKGROUND: Posttraumatic stress disorder (PTSD) is a risk factor for obesity, but the range of behaviors that contribute to this association are not known. PURPOSE: The purpose of this study was to examine associations between self-reported PTSD symptoms in 2007, with and without comorbid depression symptoms, and three problematic overeating behaviors in 2010, and to estimate the associations of PTSD-related overeating behaviors with obesity. METHODS: Cross-sectional and longitudinal analyses included 7438 male (n = 2478) and female (n = 4960) participants from the Growing Up Today Study (mean age 22-29 years in 2010)...

Coherence of mind and reflective functioning may impact negative affect and interpersonal functioning over and above the effects of symptoms of depression and interpersonal problems that contribute to symptoms of binge-eating disorder (BED) and overweight/obesity. Matched samples of overweight women with BED and overweight and normal weight women without BED completed the Adult Attachment Interview, a measure of depressive symptoms, and a measure of interpersonal problems. Greater symptoms of depression distinguished women with BED from the matched comparison samples...

OBJECTIVE: Binge-eating disorder (BED) in adults is associated with alterations in executive functions (EF) and obesity. Much less is known about these relationships in adolescents, including whether poor EF are associated with eating disorder psychopathology and/or elevated body mass index. This study examined EF in response to neutral stimuli in youth with BED. METHOD: Adolescents with BED and obesity (n = 22), individually matched adolescents with obesity (n = 22), and normal weight (n = 22) completed neuropsychological tests targeting inhibition (Color-Word Interference Test), sustained attention (D2 Concentration Endurance Test), cognitive flexibility (Comprehensive Trail Making Test), and decision-making (Iowa Gambling Task)...

OBJECTIVE: Binge eating disorder (BED), characterized by recurrent episodes of loss of control overeating, is highly comorbid with overweight and obesity. Both loss of control eating and higher body mass index have been associated with poor memory. The current study sought to clarify the relationships between BED, weight and memory. Specifically, visual memory was examined, given evidence of impaired visuospatial abilities in overweight individuals and little research on visual memory in BED...

Highlight Participants were non-clinical young adults with different restrained eating levels.We assessed relations of restrained eating (RE) with regional gray matter volume (rGMV).High RE scores were related to larger GMV in specific areas related to reward.High RE scores were also linked to less GMV in regions related to response inhibition. Objective: Dieting is a popular method of weight control. However, few dieters are able to maintain initial weight losses over an extended period of time. Why do most restrained dieters fail to lose weight? Alterations in brain structures associated with restrained eating (RE) represent one potentially important mechanism that contributes to difficulties in maintaining weight loss within this group...

Given the clinical usefulness of the CFQ-BI (Cognitive Fusion Questionnaire-Body Image; the only existing measure to assess the body-image-related cognitive fusion), the present study aimed to confirm its one-factor structure, to verify its measurement invariance between clinical and non-clinical samples, to analyze its internal consistency and sensitivity to detect differences between samples, as well as to explore the incremental and convergent validities of the CFQ-BI scores in Brazilian samples.  This was a cross-sectional study, which was conducted in clinical (women with overweight or obesity in treatment for weight loss) and non-clinical samples (women from the general population)...

BACKGROUND: Palatable food access promotes obesity leading some to diet. Here, we modeled the roles of duration, intermittency and choice of access in bingeing, escalation of daily intake, and underacceptance of alternatives. METHOD: Female rats with ("Choice") or without continuous chow access, received chow or continuous (Chocolate), intermittent (MWF) long (24h, Int-Long), or intermittent short (30min, Int-Short) access to a sucrose-rich, chocolate-flavored diet (CHOC)...

PURPOSE: Secretive eating, characterized by eating privately to conceal being seen, may reflect eating- and/or body-related shame, be associated with depression, and correlate with binge eating, which predicts weight gain and eating disorder onset. Increasing understanding of secretive eating in youth may improve weight status and reduce eating disorder risk. This study evaluated the prevalence and correlates of secretive eating in youth with overweight or obesity. METHODS: Youth (N = 577) presented to five research/clinical institutions...
