This article will compare the Microlife BodyGem with the Korr MetaCheck.
Both indirect calorimetry units measure RMR – Resting Metabolic Rate / BMR – Basal Metabolic Rate
Let’s start with validation. Both indirect calorimeter devices have been validated against the gold standards of the metabolic rate testing, the Douglas Bag and the DeltraTrac Medical Cart, and have similar accuracy.
Dr. Robert Huizenga, Associate Professor of Clinical Medicine at UCLA and Medical Advisor to The Biggest Loser said “We chose to use the Microlife device based on its accuracy in comparison to other indirect calorimeters.”
Filtration
The Korr Bacteria Filter is in the device, so it doesn’t get changed with each client and it’s only replaced every 100 usages.
The BodyGem medical-grade filters are in the disposable mouthpieces, so that each client breathes through a NEW filter.
Portability
The Korr MetaCheck is a box-type design and it sits on a desktop.
The BodyGem is a compact, hand-held design, and it comes with a carry case to allow you to perform RMR measurements anywhere.
Client Measuerement Report Printing
The Korr Metacheck is designed to be used with their printer and paper. Their preprinted paper is $20 per 100 sheets. With 2 sheets per test, that’s an extra $.40 per test.
BodyGem Analyzer software is loaded on your computer and can print the 3-page client measurement summary report from any printer. No special paper is needed.
Client Diet Tracking
Korr doesn’t offer a tracking program to empower clients to monitor their Daily Calorie Intake, to hit their weight-loss goals.
Microlife clients can track their Daily Calorie Intake, macro and micronutrients, water intake and exercise, with the online MiHealthLog program.
BodyGem owners can monitor their clients MiHealthLog tracking to provide feedback and accountability with MiHealthCoach
Device Sensors
The Korr MetaCheck has a 1 year warranty and the sensors must be replaced every year at a cost of $225.
The BodyGem has 2 year warranty and NO maintenance.
Mouthpiece Pricing
Korr mouthpiece tubes are $7 each. The bacteria filter, which is changed every 100 uses, is $6.25.
BodyGem mouthpieces with integrated medical-grade filters are $9.50 each.
Device Pricing
The BodyGem System Kit is $700 less than the Korr MetaCheck System
And a 12-month payment plan is available
Device Marketing
I offer free customizable marketing fliers to help you make clients aware of the need to get their RMR tested.
