Does Fatherhood Really Make You Fat?

Some social media outlets call it the “Dad bod.” Is there something about fatherhood that makes men fat? This question arose from a study by Northwestern University that was published in the American Journal of Men’s Health. It examined the Body Mass Index (BMI) of 10,000 men. The research studied three groups: men who were not fathers, fathers who lived with their children, and fathers who did not live with their children. The studies showed an increase in BMI among men who were fathers—with resident fathers gaining the most weight.

According to the journal, men living with their children gained an average of 4.4 pounds. Non-resident dads (those who did not live with their children) gained an average of 3.3 pounds. Men who were not fathers gained 1.4 pounds.

WHY DO FATHERS GAIN MORE WEIGHT?

It isn’t clear. The study’s lead author, Dr. Craig Garfield, has some theories. Garfield, who is an associate professor of pediatrics at Northwestern’s School of Medicine, says the increased responsibilities of fatherhood, the stress of becoming a new dad, and limited time for exercise, all play a part in the process.

The details of why aren’t clear, but one thing is certain: increased weight leads to extensive health problems, including type 2 diabetes, heart disease and high blood pressure. What should fathers do? If a “dad bod” is creeping around the corner, follow these guidelines to get (and stay) fit:

HOW TO STAY FIT AS A DAD

• Exercise: Working out just 30 minutes a day can make a difference and is better than nothing.

• Eat smart: If you’re hungry all the time, the fiber found in vegetables will go a long way toward helping you feel full.

• Eat well: There’s no shortcut—fresh fruits and vegetables should have priority over fast food and red meat.

• Keep moving: Take the stairs instead of the elevator. Park farther away from the door. These little changes can add up and make a big difference.

Dr. Garfield realized there was another important aspect of fatherhood and health. Becoming a father causes many men to re-evaluate their lifestyle choices, giving them the final push and inspiration to be healthier not just for their sake, but for the sake of their children. Your doctor can help you determine what type of diet and exercise regimen is right for you.
