A groundbreaking report released by Trust for America’s Health and the Robert Wood Johnson Foundation discovered that a third of all American adults are obese, and so are a staggering one in six children. It’s a sign that the obesity problem in this country remains a huge concern, but it also contains a silver lining that should give cause for optimism.

The report found that West Virginia was the fattest state in the nation, with 37.7 percent of its populace obese, more than any other state. Several other southern states also topped the list, including Alabama and Mississippi. Meanwhile, Colorado was the least-fat state with an obesity rate of 22.3 percent.

One big positive in the report is that for the first time in the 14 years of conducting the report, one state actually showed a decline: Kansas. The rate increase in four states (Colorado, Washington, West Virginia, and Minnesota) and stayed the same in the other 45 states.

“In the past year, adult obesity rates increased in four states (Colorado, Minnesota, Washington and West Virginia), decreased in one state (Kansas), and remained stable in the rest,” the statement reads. “This supports trends that have shown steadying levels in recent years. Last year was the first time this annual report recorded any declines in adult obesity rates, with four states experiencing declines, and, overtime, growth has started to slow. In 2006, rates increased in 31 states; in 2010, rates increased in 16 states.”
