New dads gain over a stone after baby is born, research finds

First-time fathers gain an average 8.5 kilos in the year after becoming a dad, new research shows.

The 'Dad Bod' in men after the birth of their first child is not talked about very often, but it's a very real thing apparently.


According to a survey conducted by LighterLife Fast, 22% of new dads gain over a stone after the birth of their child. On average, first-time fathers gain around 8.5 kilograms - or 1st 5lbs - in the year after becoming a dad. A figure almost equal to new mums.

The research found that one in ten new dads gain the same amount of weight as new mothers within the first year.

Despite famous faces such as Leonardo DiCaprio and Vince Vaughn going public about their parental weight gain, it is still a topic that does not get discussed enough.

Over 1,500 men were subject of this survey, which also revealed the moments when new dads realised the true extent of their weight gain.

  • 25% noticed after seeing an unflattering picture of themselves
  • 27% when clothes became too snug
  • 15% after getting out of breath playing with their children
  • 26% realised they had gained weight when other health concerns were flagged

Why do new dads gain weight?

There are many reasons why first-time fathers experience weight gain. New dads get less free time, according to the survey. 74 minutes less, to be precise. Many new dads also said they do less exercise and do not spend enough time preparing meals.


There is also the inevitable loss of sleep.

Impaired sleep messes with your levels of satiety - that feeling of fullness after eating. It also leads to lower levels of testosterone and growth hormone, which can negatively impact your strength and muscle mass.

It's not all bad news, though. Investing in blackout blinds and taking advantage of available nap time can help you get the most out of your sleep. Writing out the tasks you've completed each day has also been shown to improve sleep quality.


For example, your diet can help burn stubborn belly fat. This actually demands more from your diet than it does long spells of cardio.

By getting into a calorie deficit, you will lose weight and still get to experience a social life and flexibility with your meals.
