Researchers identify brain area linked to motivational disruptions in binge eating

(Society for the Study of Ingestive Behavior) Scientists at Rutgers Brain Health Institute have discovered that a small group of brain cells in the hypothalamus called 'orexin' neurons could be a promising target for medications for controlling binge eating episodes in individuals with obesity. These neurons, named for the chemical messenger they use to communicate with other brain cells, have previously been shown to be important for addiction to several drugs, including cocaine.

AbstractPurpose of ReviewThe Yale Food Addiction Scale (YFAS) is a self-report questionnaire for the assessment of addiction-like consumption of high-calorie, processed foods. The original scale was developed in 2009 and —for its tenth anniversary—we now review studies using its revised version—the YFAS 2.0.Recent FindingsThe 11 symptoms of food addiction as measured with the YFAS 2.0 demonstrated high internal reliability and a unidimensional structure in several studies, supporting construct validity. Similar to the original YFAS, highest prevalence rates of YFAS 2.0 diagnoses were found in individuals ...

We examined the effects of the independent and combined effects of Zataria Multiflora supplementation and circuit resistance training (CRT) on selected adipokines among postmenopausal women. Forty-eight postmenopausal women were divided into four groups: Exercise (EG, n = 12), Zataria Multiflora (ZMG, n = 12), exercise and Zataria Multiflora (ZMEG, n = 12), and control (CG, n = 12). Participants in experimental groups either performed CRT (3 sessions per week with intensity at 55% of one-repetition maximum) or supplemented with Zataria Multiflora (500 mg every day after breakfast with 100 ml of water), or their combination...

Publication date: Available online 8 April 2019Source: NeuroImageAuthor(s): Jessica Weafer, Natania A. Crane, Stephanie M. Gorka, K. Luan Phan, Harriet de WitAbstractIndividuals with impulsive and addictive disorders, including drug addiction, binge eating/obesity, and problem gambling, exhibit both impaired control over behavior and heightened sensitivity to reward. However, it is not known whether such deviation in inhibitory and reward circuitry among clinical populations is a cause or consequence of the disorders. Recent evidence suggests that these constructs may be related at the neural level, and together, increase ...

ConclusionNearly 18% of post-operative patients with LOC eating met food addiction criteria on the YFAS. Co-occurrence of LOC and food addiction following sleeve gastrectomy signals a more severe subgroup with elevated eating disorder psychopathology, problematic eating behaviors, greater depressive symptoms, and diminished functioning. Future research should examine whether this combination impacts long-term bariatric surgery outcomes.

AbstractPurpose of ReviewThis review is intended to describe the role of brain stimulation in knowledge generation, treatment, and prevention of clinical disorders of indulgent eating (e.g., obesity, bulimia, binge eating).Recent FindingsAlthough both invasive and non-invasive variants of brain stimulation have been evaluated as treatments for disorders of indulgent eating, only non-invasive variants have been studied extensively. Among these, both repetitive transcranial magnetic stimulation (rTMS) and transcranial electrical stimulation (tES) have been evaluated in randomized trials; recent findings for both have been pr...

AbstractPurpose of ReviewThe purpose of this review was to examine different forms of disordered eating among individuals with excess weight, including their rates, correlates, and psychosocial treatments.Recent FindingsBinge eating/binge eating disorder, loss of control eating, emotional eating, and food addiction are all fairly prevalent among individuals with excess weight. They appear to share many of the same correlates, including broader eating disorder psychopathology, body/shape/weight concerns, depression, anxiety, and low self-esteem. Behavioral, cognitive-behavioral, and third-wave (e.g., acceptance, mindfulness...

AbstractPurpose of ReviewAdopting an addiction perspective on eating disorders and obesity may have practical implications for diagnostic classification, prevention, and treatment of these disorders. The present article critically examines these implications derived from the food addiction concept.Recent FindingsIntroducing food addiction as a new disorder in diagnostic classification system seems redundant as most individuals with an addiction-like eating behavior are already covered by established eating disorder diagnoses. Food addiction may be a useful metaphor in the treatment of binge eating, but would be inappropria...

It is not news that America is currently facing an unprecedented obesity epidemic, and one that would quickly have us learning to say no more often, resist the temptation to give in to our favorite foods and have better self-control over our eating patterns. However, contends Arlene B. Englander, this approach is as much of a problem as the epidemic itself. Diets are restrictive and often allow no room for error or introspection. And when people blame themselves for having a “bad” week, they create negative emotions which then often lead to compulsive overeating as a way to ease the pain. Englander likens this ...
