Is Obesity Passed Down Through Genes?

Body size affects our genes, putting a physical tag on the genome that can alter human physiology for good or ill. Researchers found evidence that obese fathers may pass down a genetic obesity stamp to their offspring via altered sperm. They studied genetic material in the umbilical cord blood of newborns and found that the children of obese fathers were more likely to lack a particular genetic tag linked to normal growth and development. More research is needed to determine whether this genetic tag predicts who will go on to develop chronic diseases later in life.
