谢谢，有两个问题

第一，这篇文章和《时代周刊》没有关系，它发表于《今日美国》（USA Today)报纸上。后来有个叫times-news.net的小网站转载了，这是一个南方的城市小报。翻译者误把它当成时代周刊了。

第二最后一句话翻译得不对，原文是很多肥胖者同时有高血压、二型糖尿病、睡眠呼吸暂停综合症等其他多种疾病。你不能反过来说这些病都是肥胖造成的，瘦人也可能有高血压。

我希望转载文章时能顺便查一下英文原文，现在有搜索引擎，真是很方便，很容易找到。这样可以避免一些错误广泛传播。

下面是英文原文：

Here's another good reason to lose weight: It may improve your memory and concentration, new research suggests.

 

Scientists know that overweight and obese people are at a greater risk for memory problems and other cognitive disabilities, but the latest study is one of the first to indicate that substantial weight loss improves brain health.

John Gunstad, an associate professor of psychology at Kent State University, and a team of scientists from several research centers analyzed memory tests taken by 150 people who weighed an average of 300 pounds. Many had several health problems, such as high blood pressure, type 2 diabetes and sleep apnea.

Of that group, 109 of them then had bariatric surgery — mostly gastric bypass surgery, which creates a smaller stomach and bypasses part of the small intestine. The other 41 obese patients did not have surgery.

After 12 weeks, all participants took the same set of memory tests a second time. Findings:

The surgery patients, who had lost an average 50 pounds, showed improvement in multiple cognitive abilities, including memory and executive functioning, which includes organization skills.

The morbidly obese patients, whose weight stayed the same, showed a mild decline in memory.

The improved memory for the surgery patients likely is not solely due to improved blood pressure, because only a small number went from being classified as having hypertension to no longer having it, Gunstad says.

It appears that there is another physiological process that is causing these improvements in memory, he says. "We've known for a while that diet and exercise may also improve cognition, so it's possible there are several factors that are causing these changes."

He says it's a logical conclusion that as the body becomes healthier, the brain would become healthier also.

Michael Devlin, another author on the study and a professor of clinical psychiatry at Columbia University, agrees it's important to emphasize not just losing weight but also adopting a healthy lifestyle —healthy eating and healthy activity.
