This can’t bode well for health-care costs. A new report released Tuesday by Trust for America’s Health projects that by 2030 more than half of the people in a majority of the United States will be obese. Mississippi, which is currently America’s fattest state, is expected to nearly double its obesity rate from 35 percent to 67 percent. The new report’s predictions of overall obesity even surpass government forecasts, estimating that every state will have rates of obesity above 44 percent by 2030. The numbers are reportedly based on state-by-state surveys taken by the Centers for Disease Control from 1999 to 2010.
