Your dad bod could raise your kids risk for obesity and disease before theyre even conceived

While a shocking number of women prefer to bed down with a dad bod, experts say the physique could be bad news for future fathers.New research published in Current Obesity Reports explores how a man’s overall health before and during parenthood plays a critical role in childhood development.“We found that fathers’ health is an important contributor to children’s health through biological, behavioral, and environmental pathways,” said corresponding author Matthew Landry.

While maternal health has long been linked to childhood obesity, Landry and his team set out to better understand how the condition is shaped by the role of the father.“Obesity is not simply the result of individual choices,” said Landry.

“This work highlights that obesity risk is 40 to 70 percent heritable and can be passed across generations through complex biological and environmental influences.”In 2023, the CDC estimated that 40% of Americans had a body mass index (BMI) of 30 or higher — the threshold for obesity.Current projections maintain that by 2030, 250 million children will be classified as obese.Obesity comes with a hefty list of health risks, including an increased risk of diabetes, heart disease, stroke, and certain cancers.Researchers noted that a dad with a thicker physique could adversely affect the metabolic health of children in three key ways.First, obesity alters the epigenetic signature of sperm.

These biological signals help regulate gene function in early development and can affect appetite regulation, metabolism and long-term disease risk in children.Essentially, obesity can negatively affect children from the moment of conception onward.In terms of behavior modeling, a father’s diet, parenting practices and physical activity levels directly influence the eating and exercise habits of their children.This is of significance as fatherhood often coincides with a period of weight gain and decreased physical activity, suggesting that children are more...
