Walking may lessen the influence of genes on obesity by half.
Watching too much TV can worsen your genetic tendency towards obesity, but you can cut the effect in half by walking briskly for an hour a day, researchers report at the American Heart Association’s Epidemiology and Prevention/Nutrition, Physical Activity and Metabolism 2012 Scientific Sessions.
In our study, a brisk one-hour daily walk reduced the genetic influence towards obesity, measured by differences in BMI by half. On the other hand, a sedentary lifestyle marked by watching television four hours a day increased the genetic influence by 50 percent.
The term obesity is used to describe the health condition of anyone significantly above his or her ideal healthy weight. Between 60 and 70% of Americans are either overweight or obese. Being obese puts you at a higher risk for health problems such as heart disease, stroke, high blood pressure, diabetes and more.
