    其实身材的保持，不仅仅是在某一个方面，也许你应该注重生活中更多的细节。比如说，吃饭不要吃的太饱；注意站姿；要经常运动等！甚至连经常社交都可以保持好身材，你相不相信呢？下面的文章就集中介绍了社交为什么可以保持好身材。

Keeping a busy social life amongst lots of friends may keep people slimmer than spending several hours on a treadmill, according to scientists.

　Scientists believe social activities can release a brain chemical that converts white fat into brown fat. Brown fat burns calories to generate heat, while white fat stores calories and makes us fatter.

　Converting white fat into brown fat is very difficult, normally requiring long-term exposure to cold conditions or activating part of the body's nervous system. However, scientists from Ohio State University think that having a busy social life is an even more effective way of carrying out this conversion.

　Tests on mice showed that those lived in large communities and had more space and toys lost half of their abdominal weight in four weeks, even if they ate more than those in boring, lonely environments. Researchers said that social stimulation aids weight loss.

　However, social activities make some people worried. Study author Dr Matthew During of Ohio State University said, "I'm still amazed at the degree of fat loss that occurs... We often think of stress as a negative thing, but some kinds of stress can be good for your health."

Explaining how new technology had threatened face-to-face socializing, he added, "It's not just a sedentary lifestyle and high calorie foods, but an increasing lack of social engagement."

　Co-author Dr Cao Lei said, "Loneliness is a profound factor for cancer and death; it's on par with cigarette smoking. Social engagement is very important."
