Love to Eat| We know that women gain weight with children, and doctors are now working more aggressively with pregnant moms to be on weight control. Now researchers have established that being married or living together is a strong factor for weight gain.
A study of more than 6000 women in Australia determined that over a 10-year-period ending in 2006 the 10-year-weight gain for a 140-pound woman was 20 pounds if she had a baby and a partner, 15 if she had a partner but no baby, and 11 pounds if she was childless with no partner.
After adjusting for all factors, relationship status and children were the greatest variables in weight gain. via NYTimes Study Says Women With Mate Get Heavier
