  英译汉:

  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 socializing and meeting with friends helps boost levels of brown fatin 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.

  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”。
