See How America Has Gotten More Obese in the Past 25 Years

After 25 years of steady increases, obesity rates are down in four states, and mostly stable elsewhere. Kansas and Kentucky were the only two states with increases in the past year, according to a new report based on federal data.

While rates have plateaued in some places, researchers said they are still alarmingly high, with wide disparities from one part of the country to another. In Southeastern states, like Louisiana and Mississippi, more than 1 in 3 people were obese in 2015. But in Colorado, only 1 in 5 people were obese, with similar rates in neighboring West Coast states. In both areas, rates have more than doubled since 1990.
