By: Aarontrye After noticing the tendency of shift workers to be overweight, a team of researchers from Northwestern University decided to investigate whether eating at times that conflict with the body’s natural circadian rhythms could be contributing to weight gain. They conducted an experiment on two groups of lab mice; both groups were fed a high-fat diet containing the same number of calories and both had about the same amount of exercise. The difference came in the timing of their meals; one group was fed at night, which is the normal feeding time for mice since they are nocturnal, while the other group was fed during the day, which would be their normal resting time. After six weeks, the mice fed at the “right” time had a 20 percent gain in their body weight, but the mice fed at the “wrong” time had a 48 percent gain. The wrong-time group also gained about 8 percent more body fat than the right-time feeders. Study co-author Fred Turek, professor of neurobiology and physiology in the Weinberg College of Arts and Sciences and director of Northwestern’ Tam Fry, from the National Obesity Forum, agrees. “It is groundbreaking. It really gets you thinking why this has not been done before,” he said. “It could be very dramatic if it affects whether you are going to get fat or not.” The researchers suggest eating late at night, when our body says we should be sleeping, disrupts our circadian rhythm, or internal clock, which governs not only our sleep cycles but feeding and activity cycles as well. A 2006 Institute of Medicine report that reviewed the body of research on sleep concluded that “addressing obesity will likely benefit sleep disorders, and treating sleep deprivation and sleep disorders may benefit individuals with obesity.” “I think sleep has a very important role in metabolism,” But Arble says it is also important not to lose sight of the importance of total caloric intake. “If you are taking in excess calories daily, the time you eat probably doesn’t matter—you will still gain weight,” she said. “Similarly, if by eating small meals for dinner you decrease your overall caloric intake, that could be more beneficial than timing.” She advises, however, that “for someone not consuming excess calories each day, and they’re doing everything by the book but still gain weight, maybe look into the time of day you’re eating. It could be a factor.” http://health- # # # Information about http://kashmirparadise.blogspot.com Kashmir Paradise , History of Kashmir, Fact Files, Culture, Places to visit, in http://jammukashmir.blogspot.com jammu kashmir End
