Ever wondered how many calories you need to consume each day to lose, maintain or gain weight? We utilize the Microlife BodyGem to assess your resting metabolic rate. The amount of energy in the form of calories that the body needs to function while resting for 24 hours is known as the basal metabolic rate. With our simple test, you can know exactly what your body needs to maintain your weight. Your RMR or resting metabolic rate is the number of calories your body requires to support vital body functions, if, hypothetically, you were resting in bed for an entire day.
