BodyGemŪ by HealtheTech is a handheld device that measures resting metabolic rate (RMR), the number of calories your body burns each day at rest. BodyGem helps Bally Personal Trainers understand their clients' unique metabolisms and develop personalized weight management programs. Get control in managing nutrition, weight, and general fitness with BodyGem.
What Is Metabolism?
Metabolism is the biochemical process of combining nutrients with oxygen to release the energy needed for the body to function. Total metabolic rate represents the calories needed for maintaining body functions, daily activity (occupational and lifestyle), the thermic effect of food, and the energy cost of exercise.
What Is RMR?
Resting metabolic rate (RMR) represents the calories the body uses to maintain vital body functions (heart rate, brain function, and breathing). In simple terms, it is the number of calories a person would burn if awake, but at rest, all day. RMR represents between 60-75% of total metabolism in a healthy individual.
Why Measure RMR?
Most registered dietitians and physicians recognize that metabolism is impacted not only by gender, age and height, but also by unique characteristics such as illness, body composition, professional activity and weight loss. When managing an individual's weight loss or gain plan, knowledge of RMR is critically important. Traditionally, registered dietitians and physicians who have not had access to indirect calorimetry have relied on estimates of RMR. Because metabolism is different among individuals and can vary greatly by person, estimating can lead to under- or over-feeding, which can negatively impact a client's weight outcome. Measurement of oxygen consumption and energy requirements is the most accurate basis for administering appropriate nutrition.
BodyGemŪ by HealtheTech is the first handheld indirect calorimeter that quickly and accurately measures a patient's oxygen consumption to determine caloric needs. Measuring oxygen consumption, rather than using population based predictive equations, allows Bally Personal Trainers to determine the caloric level required for their client to achieve their desired results.
How Do You Measure RMR?
Since oxygen is used in the metabolic process to create energy, you can determine a person's metabolic rate by measuring how much oxygen they consume when breathing. To measure oxygen consumption, a process called indirect calorimetry is used. Oxygen consumption measurements are typically done with a medical device called a metabolic cart. Metabolic carts are relatively expensive, $20,000-$50,000, require technical expertise to operate, and require routine maintenance and calibration.
The introduction of BodyGemŪ makes the measurement of oxygen consumption accessible and affordable. This simple breath test takes about 10 minutes and is done conveniently and easily in your local Bally club.
Why Is RMR Unique to Each Person? Why Would It Change?
RMR is influenced by a number of factors, such as body mass, body composition, age, gender, and hormones. The metabolic response to a change in body composition (fat loss or muscle gain) influences RMR and necessitates a re-measurement of oxygen consumption to ensure that the weight management plan you are on will continue to work for you. Predictive equations do not take into account an individual's unique body composition. Repeated measurement of oxygen consumption will ensure that the client has the most accurate and up-to-day information from which to build a sound weight management plan. This re-measurement should take place about every four weeks.
