The latest obesity numbers for the nation are in, and they aren't pretty.

Obesity rates continued to climb in 31 states last year, and no state showed a decline, according to the Trust for America's Health, a research group that focuses on disease prevention.

Mississippi became the first state to crack the 30 percent barrier for adults considered to be obese. Colorado continued its reign as the leanest state in the nation with an obesity rate projected at 17.6 percent.

New York has adult obesity rates of 21.7 percent, ranking it the 36th heaviest in the nation.
