Korr MetaCheck Comparison To The BodyGem

BodyGem Indirect CalorimeterThis article will compare the Korr MetaCheck with the Microlife BodyGem.

Both indirect calorimetry units measure RMR – Resting Metabolic Rate / BMR – Basal Metabolic Rate

Let’s start with validation.  Both indirect calorimeter devices have been tested against the gold standards of the metabolic rate testing, the Douglas Bag and hospital devices such as the DeltraTrac Medical Cart.

Our device is being used to assess metabolic changes in The Biggest Loser™ contestants. “We chose to use the MedGem device based on its accuracy in comparison to other indirect calorimeters.” said Dr. Robert Huizenga, Associate Professor of Clinical Medicine at UCLA and Medical Advisor to The Biggest Loser

The BodyGem is the same type of indirect calorimeter as the MedGem, but it’s designed for professionals who don’t need to make insurance claims.


The Korr Filter is in the device, so it doesn’t get changed with each client. The filter is replaced every 100 usages.

The Body Gem filters are in the disposable mouthpieces, so that each client breathes through a NEW filter.

The BodyGem is a compact, hand-held design, and it comes with a carry bag to allow you to perform RMR measurements anywhere.
