Despite all of the health warnings in recent years, America is fatter than ever.
A new study found that America's obesity crisis has increased dramatically in the last 20 years.
It says the epidemic is going to get worse in the years ahead unless the country makes a dramatic effort to stop it.
"When you look at it year by year, the changes are incremental," said Jeffrey Levi, executive director of the Trust for America's Health, which wrote the report with the Robert Wood Johnson Foundation.

"When you look at it by a generation you see how we got into this problem." Levi said.
The study says a dozen states topped 30 percent obesity in 2010, most of them in the South.
Alabama, West Virginia, Tennessee and Louisiana were close behind Mississippi. Just five years ago, in 2006, Mississippi was the only state above 30 percent.
No state decreased its level of obesity, which is defined as a body mass index of 30 or more.
