When hearing the word obese most people think of the extreme ends of the spectrum, but this is not correct.

It’s not very helpful that the definition of obese is a bit vague because bodies are pretty different.

So it can be a BMI of
因此，BMI（身体质量指数）可以是……
over 30, your waist to hip ratio or a body fat percentage of over 25% for men and over 32% for women.
年龄超过 30 岁的人，如果其腰臀比（ waist-to-hip ratio ）超过一定标准，或者男性体脂百分比超过 25%、女性体脂百分比超过 32%，则属于需要关注健康风险的人群。

How did we get here?
我们究竟是如何走到这一步的？
For most of our history, food was scarce.
在我们历史的大部分时间里，食物都十分稀缺。
So when our ancestors found a calorie bomb, binging on it was the best of ideas.
因此，当我们的祖先发现某种高热量的食物时，尽情地食用它无疑是最好的选择。
The more sugar, fat and salt the better!
糖、脂肪和盐的含量越高越好！
Our brains are wired to love these foods, they bring pleasure, enjoyment and mental release.
我们的大脑天生就“喜欢”这些食物——它们能带来愉悦感、满足感，以及精神上的放松。
This helped us survive in a world where food was the most important thing to worry about each day.
这帮助我们在一个食物是人们每天最需要关心的事情的世界里生存下来。
And then the world changed overnight and suddenly our modern food environment hijacked our biology.
然后，世界在一夜之间发生了翻天覆地的变化；突然间，我们所处的现代饮食环境开始操控我们的生理机能（即我们的生物学机制）。
Food is a product now and has become cheap, calorie-dense and hyperpalatable – which means it has been engineered with addictive levels of sugar,
如今，食物已经变成了一种商品；它们价格低廉、热量高且极其美味。这意味着这些食物在加工过程中被添加了过量、容易让人上瘾的糖分。
fat and salt – making our reward centers go ballistic with joy.

And this is very subtle – most
而这其实非常微妙……大多数人可能都意识不到这一点。
people don’t get overweight because they massively lack self control, they just eat a little bit too much over a long period of time.
人们之所以超重，并不是因为他们完全缺乏自制力，而是因为他们在很长一段时间里摄入的热量稍微超过了身体所需。
Just a small excess, like the equivalent
只是稍微超出了标准而已，相当于……
of half a snickers over your maintenance calories per day, compounds to almost 5 kg or 10 pounds of fat after a year.
每天因为自己所需的“维持热量”而感到一丝无奈或沮丧（哪怕这种情绪只是轻微的），一年后这些情绪累积起来，最终可能导致身体增加近5公斤（10磅）的脂肪。
This is how most people get obese, slowly bit by bit.
大多数人就是这样逐渐变得肥胖的——一点一点地，不知不觉中。
Since being overweight is also shamed on top of being unhealthy, we tried to fix our overeating behavior with all sorts of…
由于超重不仅会带来健康问题，还会招致他人的指责和嘲笑，我们尝试通过各种方法来纠正自己的暴饮暴食行为……
well, behavioral methods.

The world is filled with diets and healthy habits campaigns – but if we look at the results,
世界上充斥着各种饮食计划和倡导健康生活习惯的活动，但当我们看看实际效果时……
