BodyGem Indirect Calorimeter to Measure RMR

The BodyGem® Indirect Calorimeter

Provide a higher level of care to your clients with scientifically determined resting metabolic rate (RMR) measurement (1)

The BodyGem indirect calorimeter device, is a state-of-the-art, handheld device that accurately measures oxygen consumption (VO2) to determine resting metabolic rate.

The measurement is easy to administer and provides accurate results in only a few minutes. The easy to use device allows for personalization and accurate development of individual nutrition and weight management goals.

With each BodyGem comes the BodyGem® Analyzer professional companion software. BodyGem Analyzer allows for easy monitoring of real-time measurement data, export feature for further data analysis, and report generation for patient education.

A wide variety of health and fitness professionals – Personal Trainers, Dietitians,
fitness clubs, and many others – use the BodyGem, to ensure accurate and reliable measurements for use in their weight management programs.

  • Simple – To perform a measurement, your patient or client simply breathes into the device, which measures their oxygen consumption (VO2), the resulting RMR number is clearly displayed on the device’s LCD screen.
  • Accurate – It has been validated against the gold standard Douglas Bag, and other commonly used metabolic carts (2,3,4)
  • Convenient – It is portable, self-calibrating, easy to administer, and provides a result in 10 minutes or less.
  • Affordable – It’s is available in different measurement capacities to ensure your organization has the right device for your needs.

I’m able to provide my clients with a scientific, proven solution.
Over 90% of my clients are achieving their goals.
