(SYDNEY MORNING HERALD) — Dad bod is real. Science says so.
Men who become fathers experience weight gain and an increase in body mass index, a measurement of body fat based on height and weight, according to a new, large-scale study that tracked more than 10,000 men over a 20-year period. Men who didn't become dads actually lost weight over the same time period.
The findings by Northwestern University's Feinberg School of Medicine were published Tuesday in the American Journal of Men's Health. Researchers describe the study on fatherhood and young men's BMIs as the first of its kind.

"Fatherhood can affect the health of young men, above the already known effect of marriage," lead author Craig Garfield, a Northwestern associate professor, said in a release. "The more weight the fathers gain and the higher their BMI, the greater risk they have for developing heart disease as well as diabetes and cancer."
