The residents of some U.S. states are fatter than others.

Adult obesity now exceeds 30% of the population in 20 U.S. states. In 2014, the rates of obesity surpassed 35% in three states — Arkansas (35.9%), West Virginia (35.7%) and Mississippi (35.5%) — 22 states have rates above 30%, 45 states are above 25%, and every state is above 20%. Arkansas has the highest adult obesity rate at 36%, while Colorado has the lowest at 21%, according to an annual report, “The State of Obesity,” released by Trust for America’s Health, a Washington, D.C. health policy group, and the Robert Wood Johnson Foundation, a nonprofit organization dedicated to public health.
