A study published in the Journal of the American Medical Association found that being ove
rweight did not increase the risk of dying from heart disease and cancer.

"You should not take heart in the idea that if you are only overweight you are OK," said Dr. Robert Kushner, a professor of medicine at Northwestern University who specializes in nutrition and diet.
