BBC News: 专家表示 根本不存在肥胖危机

Obesity is a problem everywhere. Obesity. And obesity crisis. Obesity problem. Obesity. Obesity crisis. Obesity is a global epidemic. The truth is there is no obesity crisis. What? Our fixation on weight is keeping us from doing things to help people get healthy. Obesity researchers hate it when I say this, but their own data show that obesity is not going to kill us. Most obese people don't have shorter lifespans than non-obese people and actually it's the underweight people who are at most at risk. Obesity only really leads to shorter lifespans at the very highest weights.
肥胖问题已成为一个普遍问题。肥胖……肥胖危机……肥胖问题……肥胖……肥胖危机……肥胖是一种全球性流行病。然而真相是：根本没有什么肥胖危机。很惊讶吧！人们对体重的执念阻止了我们去做某些事，并以此来帮助人们保持健康。肥胖专家们都讨厌我这么说，但是他们自己的数据却显示，肥胖并不能致人死亡。大多数肥胖者的寿命并不比非肥胖者短，而且事实上，反而是偏瘦的人风险最大。只有在体重极度超标时，肥胖才会导致寿命缩短。
So why does everybody think obesity is deadly? Well, one reason is that obesity is correlated with three different things that we do know is deadly and they do shorten lifespan. Being sedentary. Having lower income. And not getting enough medical care. Everyone, the media, the medical community operate from the unwavering assumption that obesity is deadly. So any evidence that comes along that contradicts that, they just write it off. It is true that obese people are more likely to get diabetes and cardiovascular disease. But there are two things you need to realize. First of all, the obesity paradox. When obese people get these diseases, they're less likely to die of them than non-obese people. What? They're less likely to die of them than non-obese people. And second, to reduce your risk for those diseases, you don't actually have to get thin. You just need to exercise.
那么，为什么大家都觉得肥胖是致命的呢?一个原因是，肥胖与三件已知的会致命且会导致寿命缩短的事情有关。其一，久坐；其二，收入较低；其三，未获得足够的医疗保健。每个个体，媒体，还有医学界，都依据一个坚定的假设——肥胖是致命的——来行事。所有从这一假设出发得出的与之相悖的结论，都会直接被大家忽略掉。虽然，肥胖者确实比非肥胖者更容易患上糖尿病和心血管疾病，但有两件事你要知道。第一，肥胖悖论。与患病的非肥胖者相比，那些患病的肥胖者死于这些疾病的几率相对要小。很惊讶吧！这些疾病对肥胖者的致死率要小于对非肥胖者的致死率！第二，事实上为减少患上这些疾病的风险，并不一定非要去减肥。你需要做的只是去运动。
