More and more Americans are obese. A new report from the Centers for Disease Control and Prevention says as of 2009 more than 26 percent of American adults were heavy enough to be considered obese. That's up from 25 percent in 2007.The study was based on phone calls to 400,000 Americans who were asked to report their height and weight.

Earlier this year, the CDC released results of another study that actually weighed and measured 5,700 adults. It found that 34 percent are obese. Three other studies have shown similar results.

The report finds that the annual cost of treating obesity soared to $147 billion in 2008. Experts say it costs about $1,400 more per year to care for an obese person than a person with proper weight.
