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. http://www2.macleans.ca/2011/09/15/get-the-skinny-on-shut-eye/#.TnOB3g4sj5s.email
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.

Junk food addiction may be clue to obesity: High-calorie bingeing as addictive as cocaine, rat study shows
msnbc.msn.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.
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.

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.

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.

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.

Monkey diets offer new clue on
binge eating:
Monkeys under stress more likely to binge
on banana chips
ABC News (May 21, 2008) by Sharyn Alfonsi, Kiran Khalid and Stephanie Dahle — Many believe the worst day at work can be curbed by inhaling a big tub of ice cream, but now scientists have found new evidence suggesting that bingeing isn't our fault -- it's biology. http://abcnews.go.com/GMA/story?id=4900179&page=1
ScienceDaily (Feb. 4, 2007) — The first national survey of individuals with eating disorders shows that binge eating disorder is more prevalent than either anorexia nervosa or bulimia nervosa. The study, conducted by researchers at Harvard-affiliated McLean Hospital, also calls binge eating disorder a "major public health burden" because of its direct link to severe obesity and other serious health effects. http://www.sciencedaily.com/releases/2007/02/070203103249.htm
