Childhood binge eating: Families, feeding, and feelings  ScienceDaily (June 28, 2016) – In order to put childhood binge eating into context, a new systematic review identifies two potential risk factors for binge eating in children under the age of 12. With family being the most proximal and influential setting affecting behaviors and attitudes in children, the study reports that parental non-involvement or emotional unresponsiveness and weight-related teasing in the family are behaviors consistently associated with childhood binge eating. … more

Overeating may cause more eating by cutting off fullness signal  MNT Medical News Today (June 16, 2016) by Catharine Paddock – Overeating can lead to more eating, setting up a vicious cycle that promotes obesity. Now, a new study suggests one way this cycle works is that when the gut senses too many calories, it shuts off a hormone that tells the brain we are full. The new study suggests that when we eat too many calories, our gut stops producing a hormone that tells the brain we are full. In the journal Nutrition & Diabetes, researchers at Thomas Jefferson University, Philadelphia, PA, describe how they came to this conclusion after observing mice on high-calorie diets. … more

Binge Eating and Impulsivity   Gurze-Salucore Eating Disorders Catalogue (June 1, 2017) by Dr. Cari Pearson Carter – Binge eating, which involves consuming an unambiguously large amount of food while feeling a sense of loss of control (American Psychiatric Association, APA, 2013), occurs across eating disorders … A useful way to understand the development of eating disorders is that initial binge eating is typically considered an impulsive or rash act. … more

Binge eating trigger point located deep inside brain  MNT Medical News Today (June 1, 2016) by Catharine Paddock – Scientists  believe they have located a point deep in the brain that links an external trigger to binge-eating or drug-seeking behavior. They found when they switched off certain brain cells in that location, rats that had once responded excitedly and speedily to cues for sugar – much like binge-eating – responded with less motivation and urgency. The finding could lead to new ways to help people reduce addictive behavior, they suggest. … more

Novel Drug Shows Promise for Binge Eating Disorder   Medscape (May 31, 2017) by Pauline Anderson –  A novel dopamine and norepinephrine reuptake inhibitor is showing promise in patients with binge eating disorder (BED).

Prenatal stress predisposes female mice to binge eating  ScienceDaily (May 30, 2017) – Stress changes our eating habits, but the mechanism may not be purely psychological, research in mice suggests. A study has found that stressed mouse mothers were more likely to give birth to pups that would go on to exhibit binge-eating-like behavior later in life. The pups from stressed mothers shared epigenetic tags on their DNA, but these markers only made a difference when the researchers put the young offspring into a stressful situation. … more

A flip switch for binge-eating?  ScienceDaily (May 25, 2017) – Researchers have identified a subgroup of neurons in the mouse brain that, upon activation, immediately prompt binge-like eating. Furthermore, repeated stimulation of these neurons over time caused the mice to gain weight. The zona incerta (ZI) is a relatively understudied part of the brain. … more

Eating healthily during the week but bingeing on weekends is not OK for your gut: no more cheat days. ScienceAlert.com (Jan 25, 2016) by Margaret Morris – A relatively healthy but complex community is living together peacefully, until an unruly mob of hooligans begins unsettling the community’s residents and disturbing the peace every weekend. This scenario could be playing out in the human gut every time you go on a junk food binge. Yo-yoing between eating well during the week and bingeing on junk food over the weekend is likely to be just as bad for your gut health as a consistent diet of junk.Our study, recently published in the journal Molecular Nutrition and Food Research, examined the impact of yo-yo dieting on the gut microbiota (the mix of organisms) of rats. This was the first study to compare how continuous or irregular exposure to an unhealthy diet can impact the composition of the gut microbiota. … more

Overeating caused by a hormone deficiency in brain? Study finds absence of peptide linked to preference for fatty food, eating for pleasure rather than hunger  ScienceDaily (July 23, 2015) – When hormone glucagon like peptide-1 was reduced in the central nervous system of laboratory mice, they overate and consumed more high fat food, scientists have found. Although this is not the only reason why people overeat, the study provides new evidence that targeting neurons in the mesolimbic dopamine system — a reward circuit in the brain — rather than targeting the whole body might be a better way to control overeating and obesity with fewer side effects. more …

‘Bad’ genes lead teens to binge-eating ScienceDaily (July 22, 2015) – Binge-eating in teenagers may be linked to a gene variation, according to new research from the University of Queensland. The UQ Diamantina Institute’s Professor David Evans and a University College London Institute of Child Health team have analysed data from 6000 adolescents aged 14 and 16 and found that genetic variations associated with obesity risk could also predict binge-eating. more …

Doctors Are Prescribing Amphetamines for Binge Eating. What could go wrong? Mother Jones (July 6, 2015) by Julia Lurie –You may have recently seen a TV ad about the “most common eating disorder in US adults”: Binge Eating Disorder. The spot features champion tennis player Monica Seles talking about her struggles with BED, which was classified by the American Psychiatric Association as a medical condition in 2013 … [a] website and the ad campaign are paid for by Shire, a pharmaceutical company that, in January, won FDA approval to market a drug called Vyvanse to treat BED. Vyvanse is a Schedule II federally controlled substance—meaning that it’s acceptable for medical use but has high potential for abuse—and it’s the only drug that the Food and Drug Administration has approved for BED.. more …

Is binge eating related to personality traits?  MNT (Apr 15, 2014) — Obesity and binge eating disorder (BED) are prevalent conditions that severely affect the quality of life of many people in developed countries, but an effective treatment remains elusive.   Personality traits have been studied extensively in this population, leading to different, and at times conflicting, results. Subtyping BED people along these features could add to our knowledge of the disorder.   more …

New treatments for binge eating, how our diet impacts brain function, and the connection between marijuana and obesity   Medical News Today (Nov 14, 2013) – A growing body of evidence shows the impact of diet on brain function, and identifies patterns of brain activity associated with eating disorders such as binge eating and purging.

Scientists identify brain circuitry that triggers overeating  ScienceDaily (Sept 26, 2013) Sixty years ago scientists could electrically stimulate a region of a mouse’s brain causing the mouse to eat, whether hungry or not. Now researchers from UNC School of Medicine have pinpointed the precise cellular connections responsible for triggering that behavior. The finding, published September 27 in the journal Science, lends insight into a cause for obesity and could lead to treatments for anorexia, bulimia nervosa, and binge eating disorder — the most prevalent eating disorder in the United States.   Link

 

Binge eating more likely to lead to health risks in men  Science Daily (Sept 17, 2013) – Binge eating is a problem affecting both men and women, however obese men who binge are more likely than their female counterparts to have elevated cholesterol and high blood pressure, finds a new study in General Hospital Psychiatry.

The biology behind binge eating   ScienceDaily (May 1, 2013) — Female rats are much more likely to binge eat than male rats, according to new research that provides some of the strongest evidence yet that biology plays a role in eating disorders.   The study, by Michigan State University scientists, is the first to establish sex differences in rates of binge eating in animals and has implications for humans. Binge eating is one of the core symptoms of most eating disorders, including bulimia nervosa and the binge/purge subtype of anorexia nervosa, and females are four to 10 times more likely than males to have an eating disorder.   Link

Binge eating may represent a sub-type of obesity most closely related to drug addiction   Medical News Today (Apr. 24, 2013) – Addiction is the continued or compulsive use of a substance, despite negative and/or harmful consequences. Over the years, addiction has come to be re-defined to include behaviors, as well as substances, and the term is now used to describe significant problems with alcohol, nicotine, drugs, gambling, internet use, and sex. The ‘major’ addictions, like alcoholism and drug abuse, stimulate significant amounts of research and are now largely well characterized, but others, like pathological gambling and internet addiction, are much less understood.   Link

Binge eating curbed by deep brain stimulation in animal model   ScienceDaily (Apr. 23, 2013)— Deep brain stimulation (DBS) in a precise region of the brain appears to reduce caloric intake and prompt weight loss in obese animal models, according to a new study led by researchers at the University of Pennsylvania. The study, reported in the Journal of Neuroscience, reinforces the involvement of dopamine deficits in increasing obesity-related behaviors such as binge eating, and demonstrates that DBS can reverse this response via activation of the dopamine type-2 receptor.   Link

Impact of portion size on overeating is hard to overcome   ScienceDaily (Apr. 16, 2013) — People given large servings of food eat more than those given smaller servings, even after they have been taught about the impact of portion size on consumption, research from the University of New South Wales shows.  Learning how to engage in mindful — rather than mindless — eating also did not decrease food intake by a significant amount in those given large servings.   Link

Revealing the scientific secrets of why people can’t stop after eating one potato chip   ScienceDaily (Apr. 11, 2013) — The scientific secrets underpinning that awful reality about potato chips — eat one and you’re apt to scarf ’em all down — began coming out of the bag today in research presented at the 245th National Meeting & Exposition of the American Chemical Society…the results shed light on the causes of a condition called “hedonic hyperphagia” that plagues hundreds of millions of people around the world.  “That’s the scientific term for ‘eating to excess for pleasure, rather than hunger…recreational over-eating that may occur in almost everyone at some time in life. And the chronic form is a key factor in the epidemic of overweight and obesity that here in the United States threatens health problems for two out of every three people.”   Link

Binge eating a hidden problem among men   msnbc.com  (Oct. 31, 2011) by Linda Carroll – People tend to notice when women binge on food — men, not so much. And that may explain why many people think that binge eating is just a women’s eating disorder.  But men are almost as likely as women to lose control in the presence of food and to suffer ill health because of their bingeing, a new study shows.   Link

Study shows why underrepresented men should be included in binge eating research  ScienceDaily (Oct. 26, 2011) — Binge eating is a disorder which affects both men and women, yet men remain underrepresented in research. A new study published in the International Journal of Eating Disorders has found that the medical impact of the disorder is just as damaging to men as it is to women, yet research has shown that the number of men seeking treatment is far lower than the estimated number of sufferers.   Link

Get the skinny on shut-eye:  Lack of sleep actually increases appetite and drives people to binge on unhealthy foods   Macleans.ca (Sept. 15, 2011) by Kate Lunau – Over 13 million Canadians are overweight or obese, but for those trying to shed pounds, giving up on a full night’s sleep for a 5 a.m. gym session might do more harm than good. Lack of sleep actually increases appetite and drives people to binge on unhealthy “comfort foods,” according to Dr. Charles Samuels, medical director of the Calgary-based Centre for Sleep and Human Performance.  Link

Binge eaters’ dopamine levels spike at sight, smell of food   ScienceDaily (Feb. 28, 2011) — A brain imaging study at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory reveals a subtle difference between ordinary obese subjects and those who compulsively overeat, or binge: In binge eaters but not ordinary obese subjects, the mere sight or smell of favorite foods triggers a spike in dopamine — a brain chemical linked to reward and motivation.   Link

Junk food addiction may be clue to obesity: High-calorie bingeing as addictive as cocaine, rat study shows  msnbc.com (Mar. 29, 2010) by JoAnne Allen, Reuters – Bingeing on high-calorie foods may be as addictive as cocaine or nicotine, and could cause compulsive eating and obesity, according to a study.  The findings in a study of animals cannot be directly applied to human obesity, but may help in understanding the condition and in developing therapies to treat it, researchers wrote Sunday in the journal Nature Neuroscience.   Link

Rats with part of brain deactivated move toward food but do not eat    ScienceDaily (Sep. 9, 2009) — Scientists led a rat to the fatty food, but they couldn’t make it eat. Using an animal model of binge eating, University of Missouri researchers discovered that deactivating the basolateral amygdala, a brain region involved in regulating emotion, specifically blocked consumption of a fatty diet. Surprisingly, it had no effect on the rat wanting to look for the food repeatedly. “It appears that two different brain circuits control the motivation to seek and consume,” said Matthew Will, assistant professor of psychological sciences in the MU College of Arts and Science and investigator in the Christopher S. Bond Life Sciences Center.  Link

High-fat, high-sugar foods alter brain receptors    ScienceDaily (Aug. 6, 2009) — Overconsumption of fatty, sugary foods leads to changes in brain receptors, according to new animal research at Johns Hopkins University School of Medicine.  The new research results are being presented at the 2009 annual meeting of the Society for the Study of Ingestive Behavior (SSIB). The results have implications for understanding bulimia and other binge eating disorders.  Link

When eating disorders strike in midlife   New York Times: Health (July 13, 2009) by Randi Hutter Epstein —  No one has precise statistics on who is affected by eating disorders like anorexia nervosa and bulimia, often marked by severe weight loss, or binge eating, which can lead to obesity. But experts say that in the past 10 years they are treating an increasing number of women over 30 who are starving themselves, abusing laxatives, exercising to dangerous extremes and engaging in all of the self-destructive activities that had, for so long, been considered teenage behaviors.  Link

Binge eating: when perfection unravels  ScienceDaily (Apr. 20, 2009) — In everyday life, someone who takes a perfectionist’s approach to activities might be admired or even rewarded with a pat on the back.  These attitudes are tied to a commonly held, but mistaken, belief that perfectionism will ultimately produce achievement and social success. But a psychologist warns that perfectionism is not a healthy, or even effective, approach to life’s challenges.  Link

Survey puts new focus on binge eating as a diagnosis   New York Times (Feb 13, 2009), by Nicholas Bakalar — Binge eating is not yet officially classified as a psychiatric disorder. But it may be more common than the two eating disorders now recognized, anorexia nervosa and bulimia.  The first nationally representative study of eating disorders in the United States, a nationwide survey of more than 2,900 men and women, was published by Harvard researchers in the Feb. 1 issue of the journal Biological Psychiatry. It found prevalence in the general population of 0.6 percent for anorexia, 1 percent for bulimia and 2.8 percent for binge-eating disorder.  Link
