研究员想了解一种方法是否比另一种方法更好。结果表明，这两种方法都很有效，每个受试者都瘦了。3个月后，慧俪轻体组的情侣减重更多（大约是7.4磅对比4.3磅），但研究最后，两组人员几乎都减掉了14磅。

On average, people whose partners joined Weight Watchers lost about 3.3 pounds in the first three months, and about 4.9 pounds over the full six-month study. Those whose partners were given a self-guided weight-loss approach had lost about 2.1 pounds at the three-month check-in, and 4.2 pounds at six months. Because of the study's margin of error, the difference between the two groups was not statistically significant.

平均而言，起初的三个月内，另一半在慧俪轻体组的受试者大约瘦了3.3磅，6个月的实验结束后，这些人瘦了约4.9磅。另一半用自我指导方法减肥的受试者在起初的三个月内大约瘦了2.1磅，6个月时瘦了4.2磅。由于研究误差，两组间的数据差异无统计意义。

Lead author Amy Gorin, PhD, a professor of psychological sciences at the University of Connecticut, said in a press release that when one person changes their behavior, it's not unusual for the people around them to change, as well. When one partner starts counting calories, weighing themselves regularly, or making healthier food choices, for example, their partners might emulate them.

康涅狄格大学的心理科学教授、首席作者艾米·戈林博士在一次资讯发布会中说道，当一个人改变自己的行为之后，身边的人通常也会做出行为变化。比如，当情侣中的某一方开始计算卡路里摄入量、定期称体重、或者吃更健康的食物时，他们的另一半可能会模仿他们。
