A new report from the Trust for America's Health and the Robert Wood Johnson Foundation finds obesity rates have risen.
Alaska ranks 30th on the list tied with Virginia. In 1995 the state ranked 17th.
In 2010 not a single state lowered its obesity rate. The report found the percentage of obese people increased in 16 states between 2009 and 2010. Researchers say most of that comes from the South, possibly because poverty rates are higher.
Researchers blame a lack of access to healthcare and places where diet is traditionally higher in fat.
Researchers say the nation is suffering from a major lack of exercise.
Richard Hamburg, the Deputy Director of Trust for America's health says a major lack of exercise has become the norm. "We have to figure out programs and policies that are going to get Americans up and walking again."
The number of adults who said they don't get any physical activity increased in 14 states last year.
