Research: Happy marriage can make you fat
Everyone has had that friend who was svelte when single and then became noticeably more plump after entering a state of marital bliss.
Now, there is new evidence that it was not your imagination: After following a group of newlyweds for four years, the researchers found that the happier you are in your marriage, the more likely it is that you will gain some extra weight.
"It's pretty widely accepted that marriage itself is associated with weight gain and divorce with weight loss," said lead researcher Andrea Meltzer, an assistant professor of psychology and a social psychologist at Southern Methodist University, in Dallas. "What is less clear is the role of [marital] satisfaction in marital weight gain."
To focus on that, Meltzer recruited 169 young couples, all married within the past six months, and followed them over four years. The husbands, on average, were 25, while the wives were 23. On eight occasions, information was collected on both their satisfaction with the union and their weight.
''Satisfaction is positively associated with weight gain," Meltzer said. "Spouses who are more satisfied tend to gain more weight, and spouses who are less satisfied tend to gain less weight."
That finding held, she said, even after compensating for such obvious factors as pregnancy. The association doesn't prove a cause-and-effect link, she stressed.
Meltzer presented the findings recently at the Society for Personality and Social Psychology annual meeting in New Orleans.
How to explain the extra pounds?
Those less satisfied with the relationship, Meltzer speculated, may be contemplating divorce. So, they might be trying to maintain an ideal weight to attract a new mate.
Those who are satisfied may be relieved that the hunt for a mate is over, and slack off on weight-control strategies. She calls this the ''mating market'' model, suggesting that weight maintenance is motivated mostly by a desire to attract a partner.
For the study, Meltzer said she did not separate out men and women, but the effect held for both genders.
