The secret of a happy marriage might be nothing more complicated than the wife being slimmer than her husband.
A four-year study suggests that, in the short and long term, both partners are more contented if the woman has a lower Body Mass Index（BMI），which is calculated from height and weight and used as a measure of obesity.
The study from the University of Tennessee selected 169 married couples aged under 35 and asked them to fill in questionnaires every six months.
They discovered that men who had a higher BMI were happier at the start of their marriage and stayed that way.
The same effect was true for the women –wives with a lower BMI than their husbands were significantly happier.
The study could perhaps shed new light on the break-up of Jennifer Lopez and her husband Marc Anthony, who is noticeably thinner than his wife.
While David Beckham and his ever-slender wife Victoria also show no sign of losing the shine from their union 11 years after the event.
But why weight matters so much?
One idea is that attractiveness and weight are more important to men. We see this emerging at the beginning of the marriage for husbands, and their dissatisfaction might be affecting wives’satisfaction over time.
Lead author Andrea Meltzer said: “Women of any size can be happy in their relationships with the right partner. It’s relative weight that matters, not absolute weight. It’s not that they have to be small."
