Today's key word is fast
fast f-a-s-t
快速的

Fast means happening, moving, or doing something at great speed速度. 快速的 这个是大家熟悉的含义。

但，fast还有另外一个含义：
If you fast, you eat no food for a period of time.
禁食，断食。

Here is an example:
I fasted for 2 days and lost 2 kilograms.
我禁食两天，两天没吃饭瘦了2公斤。

今天为啥要说fast呢？Last week, when we asked what kind of topic you guys wanted to listen to, there were several listeners who told us they were interested in topics like dieting and how to lose weight.提到diet，第一个想到的就是以前看过的一个的纪录片叫做：《进食、断食与长寿》<Eat, Fast and Live Longer>

It is a great show. 因为它回答了很多人关于减肥的疑问。Nowadays, there are an increasing number of people trying to lose weight and look younger. Many people, especially young girls like those girl groups in South Korea basically eat nothing in order to keep fit. 但是，普通人真的很难做到像韩国女子组合那样严格的控制饮食。

传说中，South Korea's girl groups like girls generation, AOA and Park Boram（朴宝蓝）only eat chicken breast, sweet potatoes and vegetables almost every day!在这些女子歌手发专辑之前，或者有重要的活动前。They can fast for days just hoping to look their best in front of the cameras. It is torture!!! 臣妾真的做不到啊！

而且，健康还是比漂亮重要一点点的。所以，今天想分享给大家之前看过的的这个节目。In this show <Eat, Fast and Live Longer>, the reporter Michael Mosley introduced several ways that are not only easier to use, but also look more scientific.

In this show, Michael has set himself a goal: he wants to live longer, stay younger and lose weight at the same time. 为了实现这些目标，他采访了美国几所顶尖科研院所。And he personally tried the ways recommended 推荐 by those experts. He discovers发现 the powerful new science behind the ancient古老的 idea of fasting, and he thinks he's found a way of doing it that still allows him to enjoy his food. 片中这位英国记者最后使用的5+2禁食法，还是不错的。

但是身体不好的童鞋，一定要慎用哦。Always remember, being healthy is more important than being pretty. Do you have your own ways to lose weight?你有没有减肥成功的方法或者经验教训，可以分享给我们呢？Tell us on our wechat, search for ayoenglish, ayoEnglish.
