We’ve known for a while that marrying before age 30 has a negative effect on women’s earning potential: according to a 2013 study at the University of Virginia, college-educated women enjoy an annual income premium of $18,152 by waiting to marry until their mid-thirties. Now, a new study from the University of Michigan has shown that although early marriage means less money, it also means more pounds. Couples who marry before college graduation have a 50 percent increased risk of becoming obese later in life than those who graduate single. Researchers say this gain is by no means inevitable, and can be avoided by paying attention to diet and exercise habits, and encouraging one another’s healthy pursuits.
