Obesity rates are still very high in the US, but they haven't increased much in recent years.
The Centers for Disease Control finds no change in the rate of obesity from 2007 to 2010.
It's estimated about one in three adults and one in six children and teens are obese, which is defined as being 20 percent or more above your ideal weight.
