Here’s the best-kept secret about weight loss: No single diet--from low carb and paleo, to low fat and vegan-will work for everyone（Excerpt）
这里是关于减重最大的秘密——无论是低碳水、史前饮食、低脂还是素食，没有一种食谱能够对所有人有效
“Why don’t they just eat less and exercise more?” he remembers thinking. Trained as a physicist, the calories-in-vs.-calories-burned equation for weight loss always made sense to him. But then his own research—and the contestants on a smash reality-TV show—proved him wrong.
“他们为什么不能少吃多运动呢？”他记得自己曾经这么想过。作为一个物理学家，他向来认为通过计算摄入与消耗卡路里的方法来减肥是合理的。但他后续的研究以及减肥电视真人秀上选手的表现，却证明他错了。
Hall, a scientist at the National Institutes of Health (NIH), started watching
The Big- gest Loser
a few years ago on the recommendation of a friend. “I saw these folks stepping on scales, and they lost 20 lb. in a week,” he says. On the one hand, it tracked with wide- spread beliefs about weight loss: the workouts were punishing and the diets restrictive, so it stood to reason the men and women on the show would slim down. Still, 20 lb. in a week was a lot. To understand how they were doing it, he decided to study 14 of the contestants for a scientific paper.
霍尔是一名美国国立卫生研究院的科学家。一年前，他在朋友的推荐下开始看《超级减肥王》。他说：“我看那些参赛者们在节目上称重，他们一周内减了20磅。”而因为节目遵循广为流传的减肥守则（即巨大的运动量加上严格控制的饮食），参与其中的男女们会瘦下来是符合常理的。但不管如何，一周减20磅还是非常多的。为了弄明白他们是怎么做到的，霍尔决定取其中14个参赛者作为科研论文的研究对象。
Hall quickly learned that in reality-TV- land, a week doesn’t always translate into a precise seven days, but no matter: the weight being lost was real, speedy and huge. Over the course of the season, the contestants lost an average of 127 lb. each and about 64% of their body fat. If his study could uncover what was happening in their bodies on a

霍尔很快发现，在真人秀的世界里，一周并不是严格意义上的七天。但无论如何，迅速且显著的减重真实发生了。在这季节目中，竞赛者平均每人减掉了127磅的体重以及64%的身体脂肪。霍尔认为，如果他的研究可以揭露这些竞赛者在

What he didn’t expect to learn was that even when the conditions for weight loss are TV- perfect—with a tough but motivating trainer,

doctors, strict meal plans and killer workouts—the body will, in the long run, fight like hell to get that fat back. Over time, 13 of the 14 contestants Hall studied gained, on average, 66% of the weight they’d lost on the show, and four were heavier than they were before the competition.
