London, Apr. 5 (ANI): American researchers have found the link between the success of a marriage and weight gain or loss.

The researchers followed 169 newly-weds for four years – and after every six months they checked the couple’s body mass index (BMI).

The results showed that the happier husbands and wives gained weight, while those who were losing weight were trying to make themselves more attractive to other partners, the Daily Express reported.

Dr Andrea Meltzer at the psychology department of the Southern Methodist University in Dallas, Texas supervised the research. (ANI)
