Obesity gene can win

Science has identified genes that are associated with weight gain and obesity. But whether they are a curse from which it is impossible to get rid of? Research shows that physical activity can prevent the "capture" of the body fat.

Several genes relevant to the weight gain But mutations   FTO obesity gene Associated with weight and obesity, apparently, are crucial. In fact, each copy of a mutation of this gene leads to a jump in weight by an average of 1, 5 kg, as scientists have found. But this genetic curse is not inevitable.

One hour of physical activity a day nullifies the "machinations" obesity gene As it became known in the course of a new study by Swedish scientists from the Institute Karolinska. Their discovery is particularly important for health care - family doctors should encourage children with a genetic predisposition to weight gain Pay particular attention to physical activity, do sport .

The researchers collected information on 720 adolescents who participated in the "Healthy Lifestyle in Europe", carried out by 10 European countries from October 2006 to December 2007. Among those teens 37% had mutations FTO, 47% had one copy and 16% had two copies of the gene.

The number of copies of the gene has been directly linked to the body mass index . However, young people with two copies, to give physical activity for at least an hour a day, the effect of a genetic mutation has been practically reduced to nothing. Their weight was kept within limits.

Also those I did sports , Each new copy FTO gene   resulted in an increase body mass index   only on days 0, 17 points higher than that adolescent without mutations. Holders of the two copies are not go in for sports This growth averaged 0, 65 per copy.
