New Jersey's government spending may be out of control, but its waistline isn't. At least for now, anyway. 

The Garden State is among the fittest places in America, according to an annual report released last week. 

New Jersey's adult obesity rate of 23.7 percent–on par with the national average–tied with the District of Columbia for 47th place in the study by the nonprofit Trust for America's Health and the Robert Wood Johnson Foundation. 

However, the report warned that if obesity rates continue on their current trajectories, by 2030, the obesity rate in New Jersey could reach 48.6 percent.

Mississippi's adult obesity rate of 34.9 percent is the highest in the country, according to the study. 

The report contends that states could prevent obesity-related diseases and dramatically reduce health care costs if they reduced the average body mass index of their residents by just 5 percent by 2030.
