An RMR test answers the question, how much should you eat? Your RMR is your body’s baseline caloric requirement. It compares the speed of your metabolism to others of your gender, age, height and weight. That is just the weight loss aspect of it. From a chronic illness and illness prevention standpoint, it measures something called EOMD or early onset mitochondrial dysfunction. This is incredibly important for gauging someone’s overall health and predicting who will stay healthy. Those who burn oxygen fast and efficiently at rest stay healthier and live longer than those who don’t.
