TED演讲【为什么节食经常不起作用】20151208【内含中英文对照演讲稿】.doc

Three and a half years ago, I made one of the best decisions of my life. As my New Years resolution, I gave up dieting, stopped worrying about my weight, and learned to eat mindfully. Now I eat whenever Im hungry, and Ive lost 10 pounds. 三年半前 我做了人生中最棒的一个决定 作为新年的新决心 我放弃了节食，停止了对自己体重的忧虑 我开始谨慎地对待进食 现在，只要我饿了我就吃 我甚至还减了 10 磅 （约为 4.55 公斤） This was me at age 13, when I started my first diet. I look at that picture now, and I think, you did not need a diet, you needed a fashion consult. (Laughter) But I thought I needed to lose weight, and when I gained it back, of course I blamed myself. And for the next three decades, I was on and off various diets. No matter what I tried, the weight Id lost always came back. Im sure many of you know the feeling. 这是我 13 岁时候的样子 那是我开始第一次节食 现在我看着这张照片，我想 我需要的不是节食 而是一名时尚顾问 （笑声）但当时我认为自己需要减肥 当我体重反弹回来的时候 我感到自责 在接下来的三十年里 我开始又结束了各式各样的节食 无论我采取怎样的努力我减去的体重总会反弹回来 我确信你们中的很多人能体会到这感觉 As a neuroscientist, I wondered, why is this so hard? Obviously, how much you weigh depends on how much you eat and how much energy you burn. What most people dont realize is that hunger and energy use are controlled by the brain, mostly without your awareness. Your brain does a lot of its work behind the scenes, and that is a good thing, because your conscious mind -- how do we put this politely? -- its easily distracted. Its good that you dont have to remember to breathe when you get caught up in a movie. You dont forget how to walk because youre thinking about what to have for dinner. 作为一名神经科学家 我很疑惑，为什么这如此困难？ 很显然，你的重量决定于 你吃了多少和你消耗了多少能量 但绝大部分人没有意识到的是 饥饿和消耗 是由大脑掌控的 大多数情况下你甚至不会意识到 你的大脑在后台做了很多事 这很好 因为你的意识 让我想个更有礼貌的说法--- 很容易被分散 当你专注于电影的时候 你不需要记得呼吸 亦可自由畅快地呼吸 你不会因为思考晚餐吃什么 而忘记如何行走 Your brain also has its own sense of what you should weigh, no matter what you consciously believe. This is called your set point, but thats a misleading term, because its actually a range of about 10 or 15 pounds. You can use lifestyle choices to move your weight up and down within that range
