打一针就能够迅速减肥?

Millions of Americans want to lose weight. On their treadmills and over their salads, they dream of a quick fix that doesn't require excessive dieting and exercise.

有无数的美国人要减肥。在跑步机上锻炼的时候，在吃低热量沙拉的时候，人们总会梦想有一种简便快速、同时又不需要锻炼和节食的减肥方法。

And the hope that those dreams could become reality got a boost this week when team of researchers at Indiana University released a study Monday in the online journal Nature Chemical Biology that showed that two natural hormones combined into a single drug suppressed appetite and increased metabolism -- in rodents, anyway.

而现在，这些梦想成真了！本周一，印第安纳州立大学的研究团队在自然科学杂志的网站上公布了一项研究成果。该成果显示，由两种天然荷尔蒙组成的某种药物具有控制食欲和加速新陈代谢的功效----反正在老鼠们身上做的实验是这样的。

"There's a global epidemic of obesity," said Richard DiMarchi, chair of the chemistry department at Indiana University in Bloomington and the study's lead researcher. "Our focus is finding therapies to lower body weight and treat diabetes."

“全世界都处在一种肥胖瘟疫中，”伊利诺伊州立大学化学系主任理查德·迪马奇说，他同时也是这个研究团队的带头人。“我们的主要目的是寻找能减轻体重和治疗糖尿病的疗法。”

A single injection of the drug decreased the rodents' body weight by 25 percent -- and fat mass by 42 percent -- after one week.

只要注射一针这种药物，仅仅一周之后，啮齿动物的体重就会下降25%，体内脂肪则减少高达42%
