The obesity epidemic is slowing down, but it's still getting worse, with a forecast out  from Duke University saying 42 percent of U.S. adults will be obese by 2030, up from just over one-third today. As bad as that is, many experts had at one time predicted it would be much worse, but rapid increases in obesity have leveled off. Yesterday's forecast also said that severe obesity is also on the rise, with the numbers set to double by 2030 so that 11 percent of adults will be nearly 100 pounds overweight or more. Despite the leveling off of the skyrocketing obesity rates of the 1980s and '90s, the Duke researchers said there are still continued small increases, and that information was used, along with other factors that influence obesity rates, including food prices, prevalence of fast-food restaurants and unemployment, to come up with the estimate. Part of the reason for the continuing rise is also that the population is growing and aging.
