Why is RMR Unique to Each Individual? Why Would It Change? Unique metabolism measured, for determination of a personalized calorie budget. With a simple breath test of 10 minutes or less, an individual can now have their Measuring oxygen consumption, rather than using population-based predictive equations, allows health and fitness professionals to make the most accurate decisions for their clients. Over the past 10 years, Microlife has harnessed revolutionary new technology to develop the BodyGem and MedGem, handheld devices that can measure oxygen consumption and determine an individual’s caloric needs. These devices are relatively expensive, $20,000 – $50,000, require technical expertise to operate, and require Oxygen consumption measurements are typically done with a medical device called a metabolic cart. Indirect calorimetry determines metabolic rate from the oxygen consumption of an individual. Direct calorimetry requires the precise measure of heat output using a large, expensive and technically complex whole body calorimeter. Metabolic rate is traditionally assessed using either direct or indirect calorimetry. ![]() Additionally, the BodyGem and MedGem devices play a significant role in providing individual’s daily caloric needs to improve individual care through nutrition assessment. The BodyGem® and MedGem® devices by Microlife are tools that will provide information vital for determining a personalized calorie budget, based on individual metabolism, necessary to achieve and maintain proper weight and nutrition. The most accurate assessment of caloric needs is by measuring oxygen consumption and determining individual metabolism. As technology advances, professionals must reassess their practices. As a result of these estimates, individuals can be both over- or under-eating, and not be successful in reaching their personal goals. Because metabolism is different among individuals, estimating can lead to errors, and inaccurate calorie budgets. Professionals, who have not had access to measurement technology, have relied on estimates of RMR. ![]() When managing a client or patient’s nutritional needs and calorie requirements, knowledge of RMR is critically important. Most healthcare and fitness professionals recognize that metabolism is impacted by a variety of characteristics such as fever, illness, high fitness, obesity, active weight loss, etc. Since RMR accounts for up to 75% of the total calories we need each day, it’s a critical piece of information to appropriately establish daily calorie needs, whether we’re trying to lose or maintain weight. RMR can represent up to 75% of a person’s total metabolism if they are inactive or lead a sedentary lifestyle. In simple terms, it is the number of calories a person would burn if they were awake, but at rest all day. Resting metabolic rate (RMR) represents the calories the body burns to maintain vital body functions (heart rate, brain function, breathing). Total metabolic rate represents the calories needed for maintaining body functions, daily activity (occupational and lifestyle), and the energy cost of exercise or planned activity. Metabolism is typically measured in kilocalories or, more commonly, calories. Metabolism is the biochemical process of combining nutrients with oxygen to release the energy our bodies need to function.

Clinical Nutrition Center is proud to offer quick and convenient metabolic rate testing with the MedGem device. The following article is from Microlife, the makers of the MedGem and BodyGem metabolic rate measurement devices.
