Socialising keeps you slim

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

They say that socialising and meeting with friends helps boost levels of 'brown fat' in the body which burns calories to generate heat.

Living in a stimulating, social environment was found to reduce abdominal fat in mice by half over four weeks, even if they ate more.

US researchers say that social stimulation aids weight loss by converting white fat into brown.

White stores calories and makes us fatter, while brown burns energy to generate heat.

Converting white fat into brown is notoriously difficult, normally requiring long term exposure to cold conditions or activating part of the body's nervous system.

However, scientists from Ohio State University now think that having a busy social life is an even more effective way of changing white fat into brown.

The team came up with their theory by studying the effects of various living environments on mice.

Those who lived alongside a greater number of mice, had more space and toys to stimulate them lost far more weight over the course of the study than their 'couch potato' counterparts.

Study author Dr Matthew During, whose team's findings appear in journal Cell Metabolism said: I'm still amazed at the degree of fat loss that occurs.

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

Co-author Dr Lei Cao said: ‘Loneliness is a profound factor for cancer and death; it's on par with cigarette smoking. Social engagement is very important.’(Agencies)

研究：社交活动有助于保持苗条身材

科学家研究发现，与在跑步机上锻炼几个小时相比，跟朋友一起参加社交活动更有利于保持苗条身材。

研究人员表示，社交活动和朋友聚会能帮助提高体内“棕色脂肪”的含量，这种脂肪可以燃烧卡路里，产生热量。

据发现，在兴奋的社交环境中生活的老鼠，四周后腹部脂肪减半，即使它们的食量增大。

美国研究者认为，社交兴奋感可以把“白色脂肪”转化为“棕色脂肪”，从而有助于减肥。

“白色脂肪”储存卡路里，使人们长胖，而“棕色脂肪”能够燃烧能量，产生热量。

“白色脂肪”转化为“棕色脂肪”出奇困难，通常需要长期暴露在寒冷的环境中，或者激活人体部分神经紧张系统。

但俄亥俄州立大学的科学家认为，繁忙的社交生活能更有效地促使“白色脂肪”转化为“棕色脂肪”。

研究小组通过研究不同的生活环境对小鼠的影响得出了这一理论。

在研究期间，和那些总是呆着不动的小鼠相比，有更多伙伴、更大空间和更多玩具的实验鼠减肥效果更明显。

研究报告作者马修?迪兰博士说：“能减掉这么多体重，我还是很吃惊。”研究报告发表在《细胞?代谢》期刊上。

在解释新科技如何威胁到面对面的社交活动时，他补充说：“这不仅会导致人们更喜欢坐着不动，吃更多高卡路里食品，而且会使人们越来越疏于社交。”

合著者曹磊（音）博士说：“孤独是导致癌症和死亡的深层因素，相当于吸烟。参加社交非常重要。”
