轻松减肥法就是每晚多睡20分钟

　　"Our findings suggest that major extensions of sleep time may not be necessary, as an extra 20 minutes of sleep per night seems to be associated with a lower body mass index," it added.

　　同时该研究还显示：“我们的调查结果表明没有必要大量增加睡眠时间，每晚多睡20分钟似乎有助于降低体重指数。”

　　"We caution that this study does not establish a cause-and-effect relationship between restricted sleep and obesity (but) investigations demonstrating success in weight loss via extensions of sleep would help greatly to establish such a relationship."

　　“我们要提醒(大家)的是这项研究的结果并不足以证明节制睡眠和肥胖之间的因果关系，(然而)调查显示延长睡眠时间确实可以成功减轻体重，这对于证明这一因果关系非常有帮助。”

　　The study was published in the Archives of Internal Medicine along with an editorial by Turek and Northwestern colleague Joseph Bass commenting on it and related research.

　　该研究结果发表在美国《内科学文献》期刊上，塔瑞克和西北大学的同行约瑟夫·贝斯共同对上述研究结果及其相关研究发表了评论。

　　In an interview with Reuters, Turek said some studies have shown sleep deprivation causes declines in an appetite suppressing protein hormone called leptin, and increases in another hormone that causes a craving for food. In addition neuropeptides in the brain governing sleep and obesity appear to overlap, he said.

　　在接受路透社采访时，塔瑞克说已经有研究表明睡眠不足会导致“瘦体素”分泌减少，而另一种增强食欲的荷尔蒙分泌增多，“瘦体素”是一种抑制食欲的蛋白质荷尔蒙。此外，他还说大脑中调节睡眠和肥胖的神经肽似乎重合在一起。

　　Obesity has been rising dramatically in developed countries and reached epidemic levels in the United States, it added, leading to a variety of health problems.

　　该研究还提到，近年来发达国家肥胖症的发病率以惊人速度增长，在美国肥胖已成为一种流行病，并且引发多种健康问题。
