Obesity is common, serious, and costly. In 2009, about 2.4 million more adults were obese than in 2007. This epidemic has affected every part of the United States. In every state, more than 15% of adults are obese, and in nine states, over 30% of adults are obese. The medical care costs of obesity in the United States are staggering. In 2008 dollars, these costs totaled about $147 billion. More efforts are needed, and new federal initiatives are helping to change our communities into places that strongly support healthy eating and active living.
