First coverage with Dr. Phil Maffetone and Professor Paul Laursen on their newly published and controversial scientific paper titled: “Overfat and Underfat: New Terms and Definitions Long Overdue.” We discuss the pandemic of people who are “overfat” — defined as having sufficient excess body fat to impair health and how this classification differs from “overweight”. If we’re to truly address the problem, we need to start using the right terminology and not hiding behind propriety (in certain situations). Doctors, researchers and individuals all need to arm themselves to take control of what some are now calling the “world health crisis”.
