As of last month, the adult obesity rate in the United States was 27.7% according to Gallup. That's up from last year's 27.1% average, which was the highest annual rate Gallup has measured.

In this animated map that The Atlantic senior editor (and former mental_floss contributor) Dr. James Hamblin shared last April, you can see the rise in obesity by state from 1985-2010. For our purposes, "obese" is defined as a body mass index of 30 or greater. As Dr. Hamblin notes, "BMI isn't an ideal metric to evaluate obesity, but it's still what the U.S. standardly uses."

The Afternoon Map is a semi-regular feature in which we post maps and infographics. In the afternoon. Semi-regularly. Thanks to James Hamblin for posting this one. One time he wrote this for us.
