It’s a common and commonly-accepted explanation: too many calories plus too little exercise is causing rampant obesity in America. But not all medical professionals agree. Is there more to this simple cause-and-effect equation?

Reporter Carey Goldberg of WBUR’s CommonHealth blog brought this very question to two leading experts here in Boston: Dr. Barbara Corkey, director of the Obesity Research Center at Boston Medical Centerr and Dr. Sarah Haigh Molina, director of the Boston University High Throughput Screening Core. Both feel that the additives in processed food might be playing a role.
