爱美的姑娘们，为了减肥大家受了哪些难以承受的折磨，又瘦了多少?小编身边的姐妹们为了减肥每天都叫苦不迭呢，也是苦了她们了，要么是将三餐改成两餐甚至一餐，要么是整日“郑多燕”陪伴，也是下了狠心了。可是效果却太令人心碎了，不是昏倒在路上就是看到吃的只能默默走开，心伤自知…所以当前程百利小编第一次看到这篇文章时，就希望可以分享给大家，正在备考的考生们，会不会帮到你们呢?(不需要减肥的大家就背单词吧)
You’ve tried everything to lose weight: portion control fasting liquid diets even eating meals on a treadmill. Now a new study suggests that maybe you should try turning out the lights. Because at least in mice exposure to light at night leads to weight gain. The work appears in the Proceedings of the National Academy of Sciences. ["Light at Night Increases Body Mass by Shifting the Time of Food Intake"]
你们为了减肥，“无恶不作”吧：是放弃美食流食减肥;还是宁可到跑步机上吃饭，一边吃一边减呢?现在有项研究你可能会感兴趣：想减肥，关灯吧!( 名为“灯光改变食物吸收时段，从而增加体重”的研究结果发布在《美国科学院论文集》)
Obesity is an epidemic. Maybe it’s because we eat too much and spend too much time in our seats. But another factor could be that these days we’re never really in the dark. Streetlamps and indoor light sources now brighten our nights. And that light pollution could be messing with our circadian rhythms which control not only sleep but metabolism. In fact mutant mice that have no circadian clocks tend to be chunky.
肥胖向瘟疫一样“可怕”吧?可能是我们吃太多，又在椅子上坐太久;又或者，我们都没在黑暗中呆过。现在到处都是的灯光让我们找不到黑夜了，这些“光污染”还打乱我们的生理节奏，不仅破坏了我们的睡眠，还阻挠我们的代谢，我们像那些研究中基因变异没有了生物钟的小白鼠，越来越胖……
To test the connection between photons and fat scientists took mice and lit up their cages. And they found that mice that were exposed to even dim light at night were chubbier than mice who spent their evenings in the dark. Though they all ate the same amount the fat mice snacked more when they were less active perhaps failing to burn off those calories.
为了探究光和肥胖的关系，科学家“又”找来了小白鼠，他们发现那些即使呆在微弱灯光下的鼠们都会比一直在黑暗中呆着的鼠胖，尽管给它们吃的食物一样，但胖鼠们吃的更多，可能因为没能消耗摄入的卡路里，它们一直饿吧!
So maybe skip the night light. Especially the one that lights up when you open up the fridge.
所以，在减肥的人们，夜里离灯光远一些好了，尤其是当你又馋了打开冰箱找吃的时，更得避开灯光了，因为又会多些要减掉的肉肉了!
