Just because someone has the genes does not mean that they will become overweight or obese, “Lifestyle such as physical activity can modify the effect.”
Researchers took a look at 12 genetic variants known to increase the risk of obesity, and then tracked the physical activity levels of more than 20,000 people. They determined that physical activity can reduce the genetic tendency toward obesity by 40 percent.
Even being active just 30 minutes a day proved to be a good start in reducing the effects of the genes.
USA Today reports:
“U.S. experts say the study adds to the data on the importance of exercise for weight control. ‘This is more evidence that behavior can modify genetic predisposition,’ says Tim Church, director of preventive medicine research at the Pennington Biomedical Research Center in Baton Rouge.”
