Staying single could help you stay slim.A new Australian study finds those who settle down gained more weight than those who remained single.

The study in the American Journal of Preventative Medicine finds young women who got married or lived with a partner gained four pounds over a 10-year period.

Not surprisingly, having a baby packed on twice as much, around nine added pounds.

Overall, partner and baby status had more to do with a women's weight than their physical activity.

Researchers suspect single women try to stay skinny to attract a mate and having a baby may cause metabolic changes leading to weight gain.
