A birthday isn’t always the most accurate measure of one’s age. That’s because there are more factors than a date on the calendar that influence how old (or young) you really are.
RealAge is one scientifically backed measure that relates your biological health to your calendar age. It does so by considering a wide array of health details, including your lifestyle habits, chronic health problems, genetics, and even your weight.
Keith Roach, MD, is an associate professor in clinical medicine in the division of general medicine at Weill Cornell Medical College and New York Presbyterian Hospital, and a co-creator of the RealAge Test. Read on to learn Dr. Roach’s insights on how weight can affect your body’s true age—and what you can do to live longer and more healthfully.
