Holiday Stress blamed for dangerous Binge-eating
Two studies in the October issue of Behavioral Neuroscience show that when animals are stressed, deprived and exposed to tempting food, they overeat, with different degrees of interaction.
The powerful interplay between internal and external factors helps explain why dieters rebound and even one cookie can trigger a binge if someone's predisposed to binge.
A study by M. Flavia Barbano, PhD, and Martine Cador, PhD, at the University of Bordeaux 2 in France, separated the distinct roles in consumption played by food deprivation and the "yum" factor, establishing that the interplay between internal and external factors regulates food intake, at least in mammals.
The brain's opioid, or reward, system governs overeating, especially when the food is extra-tempting.
These strudies may help even non-stressed people to avoid overeating, keep their weight down and improve their health.

More Sleep can help new Mothers lose prenatal weight gain...
Erica Gunderson of Kaiser Permanente, and her colleagues, made this startling discovery while studying 940 prenatal and postnatal female patients, at Harvard Medical School in Boston.
Gunderson stated: "We've known for some time that sleep deprivation is associated with weight gain and obesity in the general population, but this study shows that getting enough sleep -- even just two hours more -- may be as important as a healthy diet and exercise for new mothers to return to their pre-pregnancy weight."
Mothers who slept five hours or less a day, with infants six months old, were three times more likely to keep on their prenatal poundage.
