Metabolic Testing


We offer state of the art metabolic rate testing 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 and World Health Organization. Tricia Sauer uses this technology when working with the NFL and NHL athletes in order to best serve their needs.


Metabolic testing 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!

Due to the C19 Pandemic, this service is currently on hold as directed by the NYS Department of Health. Please contact us if you would like to be notified when this service resumes.

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?


The charge for testing is $20 per test. Please note that testing is an optional part of your appointment, and not required. This service is not covered by insurance. 

Here are the instructions for preparing for your metabolic measurement:

1) Schedule an early morning appointment, as the test must be performed first thing in the morning in a resting, fasting state.


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 minimize morning activities


4) Do not come in for testing if you are sick. This is to ensure your test result is accurate, as illness will alter your metabolic rate temporarily, and for the safety of our providers.
