If you think you may indulge yourself and pack on a few extra pounds this holiday season, you may want to think again. A new study finds that just being a little overweight can have deadly consequences.
The study, published in the New England Journal of Medicine, is a compilation of 19 separate long-term studies - the data covering 1 1/2 million patients. It found that having a body-mass index (BMI) just above the recommended range increases your mortality rate from causes such as heart disease, cancer and stroke.
Dr. Louis Aronne, director of the comprehensive weight control program at New York Presbyterian-Weill Cornell Medical Center joins American Morning's Kiran Chetry to explain why even a small amount of weigh gain can be deadly.
