减肥不成功 只因“反应慢”

 　　Some people find it more difficult to stay slim than others because their brains are slow at recognizing when they are full, a study claims.

　　The team at Yale University found that in rats some have nerve endings which are more sluggish¹ at signaling when your stomach is full than others. This means that they overeat slightly at every meal and eventually this leads to obesity².

　　The findings add to the growing evidence that it is not always your diet that leads to being overweight but also your genetic³ inheritance and pre-birth development of the brain. It also explains why two people – or siblings⁴ – can consume the same high fat diet but one remains⁵ thin while the other puts on weight.

　　"It appears that this base wiring of the brain is a determinant of one's vulnerability to develop obesity," said Professor Tamas Horvath, a neurobiologist at Yale University. "These observations add to the argument that it is less about personal will that makes a difference in becoming obese⁶, and, it is more related to the connections that emerge in our brain during development."

　　减肥不成功 只因“反应慢”

　　据英国《每日电讯报》8月2日报道，最新一项研究称，一些人比别人更容易长胖，原因在于他们对自己“吃饱”与否的感觉滞后于别人。

　　近日耶鲁大学研究小组通过研究小白鼠发现，有些小鼠的神经末梢在发送“吃饱”信号方面要比其他小鼠慢一些。这就意味着它们每餐都会吃得更多一些，最终导致肥胖。

　　研究结果更加证明了饮食并不总是导致身材走样的原因。基因遗传、产前大脑发育也是决定人们胖瘦的因素。该研究也说明了为什么两个人——或者兄弟姐妹——吃着同样的高脂肪食品，一个却还是那么瘦，另一个却日渐变胖。

　　“看来大脑基本构造是人们超重的决定因素，”耶鲁大学神经生物学教授塔玛斯说道。“研究更进一步证实了，个人意愿对减肥的作用并不大，起作用更多的还是大脑发育时产生的各种联系。”
