Dual-Energy X-Ray Absorptiometry (DEXA). DEXA is the most accurate method for body composition analysis trusted by doctors, medical researchers, and sports labs around the world. Based on a three-compartment model that measures bone mineral content, fat mass (FM) and fat-free mass (FFM), it is fast and non-invasive. DEXA body composition has been regarded as the gold standard measurement tool for its accurate and reliable results.

How is RMR calculated?
There are three possible ways that the DXA RMR result can be calculated. This is the explanation that comes from the operator’s manual and note that there are three ways to calculate RMR: Harris-Benedict, Mifflin-St. Jeor or enter manually.
The Harris-Benedict equation is:
RMR(male) = 66.473 – (6.775 x age[yrs]) + (13.7516 x weight[kg]) + (5.0033 x height[cm])
RMR(female) = 655.0955 – (4.6756 x age[yrs]) + (9.5634 x weight[kg]) + (1.8496 x height[cm])
where weight is the entered patient weight.
The Mifflin-St. Jeor formula is:
413 + 19.7 x FFM (kg)
where FFM (Fat Free Mass) = Lean mass (kg) + Bone mass (kg)
 Harris JA, Benedict FG. A biometric study of basal metabolism in man. Washington, DC: Carnegie Institute of Washington, 1919. (Carnegie Institute of Washington Publication 279)
As you can see, only the Mifflin-St Jeor method uses the DXA results.
Patient instructions and FAQ:
A client’s scan begins with a 15-minute consultation with our doctor to review all of your goals, answer any questions you may have, obtain consent and provide you with your referral. You will then perform the DEXA right after, which will take an additional 15-minutes for the test and review of results with our doctor.
If you have never had a scan, we recommend our clients to get the 2 scans so that you can have a before and after comparison to evaluate any programming you may be doing.
The DEXA scan generally takes a total of 30 minutes to complete. It is totally painless and the process is very straightforward. DEXA utilizes a very low dose x-ray equivalent to the amount of radiation you would receive while on a flight to New York City. Different from other types of tests such as MRIs or CT scans, there is no oppressive, closed tunnel or ring. Simply lie on your back, breathe comfortably and relax. The scanner does the rest. When finished our team will review your results. We will also provide you with your detailed report to take home.
Please wear or bring with you loose athletic clothing (no metal). For best accuracy of your measured weight, try not to eat a large meal immediately prior to the test. For example, for a morning test, you may want to test before having a large breakfast. In the afternoon, test before having lunch and in the evening, test before having a large dinner.
We also try to offer same day appointments for all clients and we are open 9 am – 8 pm Monday to Friday. Our phone number is 416-722-3393. We look forward to hearing from you, please request your consultation today!
