Researchers at T.H. Chan School of Public Health at Harvard University, who will have their findings published Wednesday in the New England Journal of Medicine, also suggest that more than half of the population in 29 U.S. states will be obese.

Currently, the analysis estimates that 40 percent of American adults are obese, with 18 percent severely so.

“Prevention is going to be key to better managing this epidemic” of obesity,” lead author Zachary Ward, programmer/analyst at Harvard’s Center for Health Decision Science, said in a press release.
