Committing to a weight-loss program can have an unexpected benefit: Your significant other may shed some extra pounds, too, even if they aren't trying. That's what researchers found in a study on the so-called weight-loss ripple effect, published today in the journal Obesity. 致力于减肥计划可能会带来意想不到的收获：你的另一半或许也能减重几斤，即使他们根本就没有减肥的打算。在一项有关所谓的减肥连锁效应研究中，研究员发现了这一点，该研究于今日发表在《肥胖》杂志上。 The study, which was sponsored by Weight Watchers, tracked the progress of 130 married or cohabitating couples for six months. In all of the couples, one partner had a desire to lose weight, and both partners agreed to weigh-ins after three and six months. Half of the partners followed Weight Watchers, while the others received a four-page handout with healthy-eating and exercise tips, and were told to try to lose weight on their own. 该研究由慧俪轻体（Weight Watchers）赞助，在6个月的时间内对130位已婚或同居情侣的减肥情况进行跟进。在所有情侣中，一方有意愿减肥，双方都同意三个月和六个月后各称一次体重。一半的情侣遵循慧俪轻体机构的减肥方法，其余情侣则收到了一份四页纸的健康饮食和锻炼建议，研究员让他们凭自己的努力减肥。 |
