Scientists know that the type of fat you can measure with a tape isn't the most dangerous.But what is the most effective way to fight internal,visceral fat that you cannot see or feel?The answer:exercise.

　　科学家们知道外在的由尺子测量出来的肥胖并不是最可怕的，那对抗腹部肥胖(就是那些感觉不到看不到的内脏脂肪)最有效的方式到底是什么呢?

　　答案就是：运动。()——我也要好好运动了。

　　西南医学中心的研究人员分析了两种类型的干预措施

　　Researchers at UT Southwestern Medical Center analyzed two types of interventions--lifestyle modification(exercise)and pharmacological(medicine)--to learn how best to defeat fat lying deep in the belly.The study is published in Mayo Clinic Proceedings.

　　西南医学中心的研究人员分析了两种类型的干预措施——生活方式的改变和药物使用——来了解如何更好的减少腹部脂肪的堆积。

　　这项研究的结果发表在Mayo Clinic Proceedings上面。

　　"Visceral fat can affect local organs or the entire body system.Systemically it can affect your heart and liver,as well as abdominal organs,"said senior author and cardiologist Dr.Ian J.Neeland,Assistant Professor of Internal Medicine."When studies use weight or body mass index as a metric,we don't know if the interventions are reducing fat everywhere in the body,or just near the surface."

　　内脏脂肪可以影响局部器官功能甚至整个身体系统的功能。他可以影响你的心脏、肝脏甚至你的腹部器官。内科医学助理Ian J.Neeland博士说，当我们使用体重或者BMI作为衡量指标时，我们很难清楚地了解到我们到底是减少了哪里的脂肪，或者我们

　　To find out,the researchers evaluated changes in visceral fat in 3,602 participants over a 6-month period measured by a CT or MRI exam.Both exercise and medicines resulted in less visceral fat,but the reductions were more significant per pound of body weight lost with exercise.

　　为了搞清楚，研究者利用CT或MRI随访了3602名志愿者6个月来检测他们腹部脂肪的变化。运动和使用药物都可与减少腹部脂肪，不过每公斤下降的体重中脂肪运动

　　"The location and type of fat is important.If you just measure weight or BMI,you can underestimate the benefit to your health of losing weight,"said Dr.Neeland,a Dedman Family Scholar in Clinical Care."Exercise can actually melt visceral fat."

　　脂肪生成的部位和类型很重要，如果你只是称体重或者计算BMI，你可能会低估减重对你身体的益处。运动确实可以“溶掉”你的腹部脂肪。

　　Participants in exercise trials were 65 percent female,with a mean age of 54 and mean BMI at enrollment of 31.Exercise regimens were monitored,not self-reported.The majority of exercise trials were performed in the U.S.and Canada,while pharmacologic trials included the U.S.,Canada,Sweden,Japan,and four multinational cohorts.

　　参与运动组的志愿者65%是女性，平均年龄54岁，BMI的平均值是31.参与运动组的志愿者65%是女性，平均年龄54岁，BMI的平均值是31.运动方案由系统检测，并非志愿者自我上报，这样就减少了偏差。大多数的运动干预试验在美国和加拿大进行，而药物试验部分则安排在美国，加拿大，瑞典，日本和四个多中心试验组。

　　The medications used by study participants were FDA approved or in the FDA approval pipeline.

　　研究参与者使用的药物是FDA已批准或者正在申请获批中的。

　　According to the Centers for Disease Control and Prevention,obesity affects nearly 40 percent of adult Americans.Dr.Neeland said researchers previously thought of fat as inert storage,but over the years this view evolved and fat is now seen as an active organ."Some people who are obese get heart disease,diabetes,or metabolic syndrome--and others don't,"Dr.Neeland said."Our study suggests that a combination of approaches can help lower visceral fat and potentially prevent these diseases."

　　根据疾病防控中心的数据，美国有40%成年人身体肥胖。

　　Neeland博士说，研究人员以前认为脂肪是惰性物质，但多年来这种观点逐渐发展，脂肪现在被视为一种活跃的器官。“一些肥胖的人患有心脏病，糖尿病或代谢综合症-而其他人则没有，”德博士说。“我们的研究表明，多种方法可以帮助降低人体内脏脂肪，并有可能预防上面这些疾病。”
