BodyGem and MedGem Differences

by David on February 5, 2010

The BodyGem and MedGem are both indirect calorimeters, that determine RMR – Resting Metabolic Rate, to help clients optimize their weight loss results.

Instead of estimating RMR, the BodyGem and MedGem scientifically measure a clients Metabolic Fingerprint, that is unique to them.

The BodyGem is designed for Personal Trainers, fitness facilities and Dietitians who don’t make insurance claims for their services.

The BodyGem displays RMR readings and works with the BodyGem Analyzer companion software.

The BodyGem System is a lower priced option, because it has no associated FDA-approval costs, so it helps you increase your profitability.

I specialize in helping Personal Trainers, fitness facilities and Dietitians, get a BodyGem to help optimize client weight management results and to increase profits.

The MedGem can only be sold to licensed clinicians because it is a  FDA-approval medical device.

The MedGem displays RMR and Resting Vo2 readings (for patient diagnosis, not Max VO2 testing)

Bariatric Doctors, Dietitians and other licensed clinicians may be able to make insurance claims using designated CPT codes.

Contact me to see if the MedGem or the BodyGem indirect calorimeter is the best fit for your needs.

To get more information:

  • Call me directly at 720-431-1461
  • Or leave a voicemail at 1-866-285-8296 and I’ll call you back

I wish you the best of health!

What is the life expectancy of the MedGem, that is, are there sensors that need to be replaced after a certain number of uses? What is the cost of the MedGem?

Is there any difference in the Body Gem vs Med Gem as it pertains to accuracy, reproducibility and warranty? Are they the same machines, merely that one is “FDA approved”? Can you give me the cost of each. Thank you.

We are a internal medicine practice looking to purchase one of the systems. I would believe the MedGem system is what we would want but if you could include pricing in both I would appreciate it.

Just curious about cost. Looking to start up a nutrition consulting business.

I work on the north shore of MA. I am interested in having indirect calorimetry performed for my patient. I have used medgem in the past. Is there any location on the north shore of MA that has a medgem and a person can get their RMR tested?

Hello David,

I’m emailing from an Australian university. Could you please give me a quote for the BodyGem and MedGem, please?
Along with this could you please forward me a quote for the mouthpieces and any other set-up costs or consumables required?

I have to submit my equipment request to the committee overseeing the funding of equipment. It is due this Thursday (Australian time). So if there is any chance of getting a quote back before then, that would be fabulous!!

Thank you,

Hi, does my client needs to be fasting for 12 hours because I take the measurement? What are the procedures to be taken before the test (fasting, alcohol, resting period before the test, physical activity, …)

Thank you!

David November 23, 2015 at 9:44 am

Hi Marie-Lou, clients should not exercise, consume stimulants, smoke, drink alcohol, or eat, during the four hours prior to the measurement.
