Metabolic Testing


We are now offering metabolic testing using a technology called Indirect Calorimetry - a breathalyzer technology that measures the thermic (heat) energy of your unique metabolism! This is the gold-standard method for determining metabolic rate recommended by the American Academy of Nutrition and Dietetics and other prominent health organizations including the Collegiate and Professional Sports Dietitians Association. Tricia Sauer uses this technology when working with the NFL Buffalo Bills players in order to best serve their needs.


The technology reveals exactly how many calories you should be eating each day, how much exercise you should be doing to manage your weight, and whether you are burning fat, carbohydrates, or both. This means no more worrying that the calorie needs equations aren't spot on due to illness, medical conditions, or a history of bad dieting! Please contact us if you are interested in utilizing this new technology at your appointment. Knowledge is power!

How exactly does it work?


Our calorimeter device uses a sensor cartridge and flow meter to determine the rate of consumed oxygen (VO2) and produced carbon dioxide (VCO2) in the breath. These values are used to determine REE and EE according to the Weir equation, as well as respiratory quotient (RQ), which is the ratio of produced carbon dioxide to consumed oxygen. Each test requires a single-use sensor cartridge, which conveys its own calibration parameters through a quick response (QR) code scan during the testing process.


How much does it cost?


We ask patients to reimburse us $10 per test, as this is the cost of the supplies needed to perform the test. Please note that testing is an optional part of your appointment, and not required. 

Here are the instructions for preparing for your metabolic measurement:

1) Schedule your appointment first thing in the morning.


2) Do not eat or drink anything besides water at least 8 hours prior to your appointment.

3) Do not exercise at least 12 hours prior to your appointment, and try to minimize morning activities until testing is complete. This is very important as we are measuring your resting metabolic rate.
