Study puts obesity rate at 42 percent by 2050

Despite reports that the obesity rate among U.S. adults might be slowing down, a new study found it may hit 42 percent by 2050.

Researchers at Harvard and MIT used a sophisticated model that viewed obesity like an infectious disease.

It found that adult obesity rates will rise for another 40-years before leveling out. The Centers for Diease Control has placed the obesity rate at 34-percent.

Authors of the study in the journal PLoS Computational Biology said it's true the percent of obese people has slowed down but their results suggest it is not the end.
