Marriage Makes You Fat: Study

As couples grow more committed to each other, their waistlines often grow as well, Time reports. During their first few years of matrimony, couples are twice as likely to become obese as their dating peers, according to a new study being published next month. If they merely move in with their boyfriends, women are 63% more likely than uncoupled peers to become obese; their partners' average risk doesn't increase, however.

Researchers tracked the weight and relationship statuses of 6,949 people and interviewed another 1,293 couples. They theorize that couples may focus more on meals while living together, might spend less time at the gym, or simply let themselves go. But don’t worry—you can shed the pounds together. A separate study last year found that when one spouse enters a weight-loss program, the other usually loses about 5 pounds. (More marriage stories.)
