不知道你们周围有没有这样一群人，他（她）们：
 
如果看见桌面上有吃的，就会立刻消灭它们；
一旦吃上一颗瓜子，就会一口气吃光一袋；
……
 其实他（她）们并不饿，就是没事儿总想吃点东西。所以这究竟是什么“毛病”？为什么有时候会不停地想吃东西？

Under normal circumstances, we feel hungry when we have burnt up the food we have eaten as energy and our blood sugar and insulin levels begin to drop. Ghrelin, a hormone connected to appetite, then communicates this to the brain, which is how we feel the need to eat.
在正常情况下，当身体把食物转为能量消耗掉之后，我们的血糖和胰岛素水平也开始降低，这时我们就会感到饥饿。然后，饥饿激素将这个信息传达给大脑。这样我们就会感觉到需要吃东西了。
 
insulin：胰岛素
Ghrelin：/?ɡr?l?n/ 食欲刺激素
 
But all sorts of things can interfere with this process. 
但是各种各样的事情都会干扰这个过程。

1. When you are tired(睡眠不足)

According to a 2011 study by researchers at Columbia University in the US, those who are sleep-deprived eat almost 300 calories a day more than those who get enough sleep. 
根据美国哥伦比亚大学2011年研究人员的一项研究，那些睡眠不足的人每天摄入的热量几乎比那些睡眠充足的人多300卡路里。
 
This is because levels of the hormone ghrelin, which tells the brain we need to eat, increase when we don't get enough sleep.
这是因为当我们没有足够的睡眠时，饥饿激素会增加，会告诉大脑需要吃欧洲杯押注软件下载_欧洲杯押注平台：的东西。
 
The Columbia researchers noted that the women who didn't get enough sleep took in more fat rising by around 30g on sleep-deprived days — four times as much as the average increase for men. 
哥伦比亚大学的研究人员指出，睡眠不足的女性在睡眠不足的日子里摄入的脂肪增加了约30克。这是男性平均增加量的四倍。

2. Troubled times（艰难时期）

In a 2013 study, people who were primed to expect "tough times ahead" ate more food than people who listened to neutral messages. 
在2013年的一项研究中，那些得知不久会遇到“艰难时期”的人会比获得中性信息的人吃欧洲杯押注软件下载_欧洲杯押注平台：的食物。
 
primed：准备好的
 
It's thought that hearing about troubled times causes a survival instinct to kick in, leading to cravings for high-calorie snacks such as chocolate. 
一听说“有麻烦了”，人的生存本能就被激发了，对巧克力等高热量零食的渴望也随之增加。

3. 'Naughty' food cravings（越内疚越想吃）

Tempted by that extra biscuit? Then just enjoy it — as researchers have found that when you feel guilty about a pleasurable experience, the guilt itself becomes pleasurable, so encouraging you to do it more.
还想再吃一块小饼干？吃就吃吧，开心一点。研究人员发现，当你对某个愉快的体验感到内疚时，内疚本身也会带来快感，进而鼓励你再次去做这件事。
 
"If we consider something a naughty pleasure, it can psychologically drive the appetite and the guilt may make you want to eat more," says Cary Cooper, at the University of Lancaster. 
兰卡斯特大学的Cary Cooper说，如果我们认为某件事会带来不守规矩的快感，它会在心理上促进食欲，而这种内疚可能会让你想要吃欧洲杯押注软件下载_欧洲杯押注平台：。
 
The appetite center of the brain also lies very close to the area governing mood — thelimbic system — which is why changes in the way we feel may affect appetite.
大脑中的食欲控制区域非常接近情绪控制区域——边缘系统——这就是为什么我们的情绪变化会影响食欲。
 
limbic：边缘的

4. Mobiles' blue light（移动蓝光设备）

The bright blue light emitted by devices such as smartphones and tablets may give an unwelcome boost to your appetite. 
智能手机和平板电脑等设备发出的蓝光可能会增进饮食。
 
Research this year found that your appetite continued to increase when you are exposed to the light. 
今年的研究发现，蓝光下你的食欲会持续增加。
 
It also altered people's metabolism, as blood tests showed that the blue-light subjects had higher insulin and glucose levels. 
蓝光的照射还会改变人们的新陈代谢。血液测试显示，接受蓝光受试者的胰岛素和葡萄糖水平都更高。
 
metabolism  /m?'t?b?l?z?m/ ：新陈代谢
glucose /'ɡlukos/：葡萄糖
 
One possible explanation is that bright blue light at night confuses our body clock, which has a role in controlling when we feel the need to eat. 
一种可能的解释是，夜间明亮的蓝光会干扰我们的生物钟。而生物钟可以控制我们什么时候觉得需要进食。
