Baby sleeping on dad

Remember that whole "dad-bod" craze? Well, it turns out that the "postbaby body" really isn't just a mom thing after all.

According to a new study published in the American Journal of Men's Health, guys gain weight after their first child—even if they don't live with their children.

Researchers followed more than 10,000 men from adolescence through their early 30s. Each man's BMI was measured at four different times. It was found that men who cohabitate with their children gain about 4.4 pounds after becoming a dad, while men who don't reside with their children gain approximately 3.3 pounds. As for the guys who didn't become dads? They actually lost 1.4 pounds during this time period.

"You have new responsibilities when you have your kids and may not have time to take care of yourself the way you once did in terms of exercise," said lead author Craig Garfield, M.D. "Your family becomes the priority." He also notes that many dads take on the responsibility of eating any food their kids leave on their plates.
