Obesity is inherited from father to child, he goes to grandchildren

Obese men can inherit their weight problems not only for their children but also their grandchildren, a new medical study reveals.

Biologists at the University of Adelaide (Australia) discovered that it all depends on the weight of the husband and father at the time of fertilization . So if you want to avoid an obese family, men need to try to reduce weight before trying to have children.

According to the team, a molecular signal in obese men 's sperm may be inherited along with problems related to overweight, including diabetes, for future offspring. Both the daughter and son of obese fathers are at risk of inheriting the weight problem in this way, although girls will face higher risks than boys.

Even if the children eat well and are active, they still have the ability to suffer the consequences of the molecular signal, although the signal appears to be slightly weakened through the later life. .

Dr Tod Fullston, head of the study, said: "The father's diet changes the molecular structure of sperm. For obese fathers, changes in their" breed "are programming for obese embryos or later metabolic diseases in life ".

Fullston added that the risk of diabetes is the same in both boys and girls, but it will be less serious even in his life. This can happen even when obese fathers do not show diabetes.

Fullston stressed: "We know that the health of the mother before, during and after pregnancy can affect the health of the child, but the health of the father during the entire period. This is often overlooked . The focus of attention on the health of the mother is extremely important, but we will have to consider father's health as equally important for the fertilization process. more to the diet and exercise of sports in the father can create a positive impact on his future children and grandchildren ".
