According to the most recent data, adult obesity rates now exceed 35 percent in four states, 30 percent in 25 states and are above 20 percent in all states. Louisiana has the highest adult obesity rate at 36.2 percent and Colorado has the lowest at 20.2 percent. U.S. adult obesity rates decreased in four states (Minnesota, Montana, New York and Ohio), increased in two (Kansas and Kentucky) and remained stable in the rest, between 2014 and 2015. This marks the first time in the past decade that any states have experienced decreases — aside from a decline in Washington, D.C. in 2010.
Overweight and obesity result from an energy imbalance. The body needs a certain amount of energy (calories) from food to keep up basic life functions. Body weight tends to remain the same when the number of calories eaten equals the number of calories the body uses or “burns.” Over time, when people eat and drink more calories than they burn, the energy balance tips toward weight gain, overweight, and obesity.
