While US obesity rates remain at historic highs, only Arkansas has seen an increase in the percentage of adults who are obese, while the other 49 states hit pause in a three-decade trend of ever-fatter populations. The latest annual obesity report from the Trust for Americas Health and the Robert Wood Johnson Foundation found that real and lasting progress is being made in the nations effort to turn back the obesity epidemic. Still, 41 states had adult obesity rates above 25%, with 13 of those exceeding 30%; Arkansas went from 30.9% to 34.5%. In 1980, not a single state had more than 15% of adults classified as obese, defined as a Body Mass Index of 30 or above. In 2012, overall the report said more than two-thirds of Americans (68.7%) are either obese or overweight (BMI 25-29.9).
