We all know that if you cut your calories, you’ll lose weight. But, if you want to make sure the weight lost is FAT (not muscle), read on…A new study published in the Annals of Internal Medicine, Annals of Internal Medicine,  put 10 overweight individuals on a diet, cutting their caloric intake by 10%. Each of them lost about the same amount of weight – 6.6 pounds. But, where the weight came from was very different. Dieters who were permitted to spend 8.5 hours in bed lost about half the weight from fat. But, those sleeping just 5.5 hours lost only about a quarter of the weight from fat. The rest was nonfat mass – such as critical protein and muscle stores.For more information, read http://www.latimes.com/health/boostershots/la-heb-sleep-fat-20101004,0,7295225.story?track=rss.
