Women who juggle career and family tend to be thinner and healthier as they approach midlife than long-term stay-at-home moms, a new study suggests. Researchers tracked the health of a group of British women from their mid-20s to their mid-50s and found that full-time homemakers were the most likely to be obese in their sixth decade. Women in long-term relationships who had raised kids while they held jobs outside the home were least likely to be overweight, and they also reported being in better overall health.
