It's little wonder that we have an obesity epidemic. Food is everywhere, from roadsides and vending machines to television and overstuffed supermarket shelves. That, coupled with a life of sitting - in cars, at desks, on couches - has set us on the road to an obesity epidemic.Data from two major surveys show that since 1980, the rates of obesity have doubled for adults and tripled for children. In 2007, only one state (Colorado) had a prevalence of obesity less than 20 percent. Thirty states had obesity rates of 25 percent or more.Though rising numbers seem to be leveling off, they are still far from the federal government's goal of reducing the obesity rate 15 % Causes and factors
Though poor diet and lack of physical activity lead the pack, a number of other factors play a role in the obesity epidemic, including:
Genetics. A family history of obesity raises your chances of becoming obese by about 25 percent to 30 percent. Genes can influence your body fat distribution and make you more susceptible to gaining weight.
