You might have thought resisting that piece of chocolate cake or extra biscuit was simply a matter of exerting a little will power. But for some of us it’s much more difficult than that – because of the way our brains are wired. 你也许会认为，抵住一块巧克力蛋糕和一块额外的饼干的诱惑，仅仅是发挥一点意志力的问题。但是对我们有些人来说，可没有这么简单，这是因为我们的大脑构造方式不同。 Scientists have found that a key part of the brain which stops the body from acting on impulse – and gorging – does not function as well in those who are overweight or obese. 科学家们近日发现，通常人大脑中阻止身体冲动行事和狼吞虎咽的关键组成部分，却没有办法在超重者或肥胖者的大脑内发生作用。 A study by scientists from Yale University has shown that falling glucose levels lead to a loss of self-control in the brain which subsequently lead to parts of the brain craving high-calorie food such as cakes, biscuits or crisps. 耶鲁大学的科学家们通过研究发现，葡萄糖水平降低会导致大脑自我控制力丧失，这将会造成大脑某些部分对蛋糕、饼干和薯片等高卡路里食物的需求。 In obese people the effect may be even more pronounced, so they are driven to eat by the slightest drop in glucose. 这种影响在肥胖人群身上表现得更为显著，一旦他们的葡萄糖出现轻微降低，他们就会因此开始吃东西。 |
