A report by the National Health and Nutrition Examination Survey of 4,356 participants has determined that 34.4% of U.S. adults aged 20 and over are obese; slightly fewer (32.7) are overweight. In a 2005-2006 study 5.9% of the population is considered “extremely obese”. Obesity has more than doubled since 1980, but overweight has remained the same.
