Can overweight men pass obesity risk to their children?
"Are you fat because of your dad?" is the Mail Online's bold question to its readers, explaining that "Men's weight directly affects genes in sperm linked to appetite and brain development".
This was based on a new study that found a man's weight influences the genes in his sperm.
This small study showed that DNA in the sperm of obese men differed from that of healthy weight men. The DNA itself wasn't changed, but modifications affecting how it's used by the body were.
These differences raised the possibility that children of overweight men could inherit genetic traits that make them more likely to be overweight themselves. Health News from NHS Choices
