Unit 71：Diet for 12 weeks第71单元：持续节食十二周Research at Harvard Medical School suggests that the human body reaches a weight-loss limit about 12 weeks into any diet and then plateaus,哈佛医学院的研究显示，人体在节食大约十二周后就会到达减肥极限期而不再减轻体重，refusing to lose another pound,at least for a while.至少有一段时间会连一磅都减不下来。Our bodies,it appears,can't stand to lose more than 5 to 10 percent of their weight at once.我们的身体似乎承受不了一下子就减掉超过身体百分之五到百分之十的体重。It's best to take a rest for another 12 weeks,giving your body a chance to adjust to the weight loss.最好是能休息一段时间，再节食十二周，让你的身体有机会来适应体重减轻。Don't revert to high-calorie eating habits,but don't strive to cut calories,either.别又开始恢复高卡路里的饮食习惯了.不过，也别试着努力想减低卡路里的摄取量。Figure out some reasonable approach between the two.在两者之间想出某种合理的方法。Then head into another 12-week dieting period and watch your weight drop anew.接着再进行十周的节食期，然后就等着看你的体重再创新“低”吧。
