It finds that women are more apt to pile on excess pounds after marriage while men add the weight after a divorce.
The study didn't examine the reasons why, but findings fit with previous research. It shows that married women often have a larger role around the house and may have less time to exercise and stay fit.
But married men, on the other hand, get a health benefit from marriage and they lose that benefit once they get divorced, which researchers say may be the reason for the weight gain.
