A Dad bod is a male body type that is best described as 'softly round.' It's built upon the theory that once a man has found a mate and fathered a child, he doesn't need to worry about maintaining a sculpted physique.
A first-of-its kind study to follow men for up to 20 years from adolescence shows that dads do get a little squishier after the kids. It's a unique look at the influence that a social phenomenon, becoming a father, has on a biological marker. It really plants fatherhood as a potential social determinant of health for men.
