Obesity maybe passed down from fathers to kids

Australian researchers at the University of Adelaide, have found that the sperm of overweight fathers appears to carry a molecular signal that causes their offspring to inherit obesity. This may be more severe in female children and males they add.
This is the first evidence that a father’s nutrition can affect the epigenome of his sperm, a non-genetic mechanism to inform the next generation of environmental change. Researchers don’t yet understand how this occurs and are particularly interested in why it appears to have a greater impact on the female offspring.
The research adds that since transfer of the obesity factor is a biological process, not a genetic one, a father who loses weight and gets fit is less likely to pass on obesity to his children.
