Metabolic Testing


We offer state of the art metabolic rate testing called Indirect Calorimetry - a breath test 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 professional 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 technology at your appointment. Knowledge is power!

Due to clinical demand, testing is reserved for existing patients and individuals who wish to work with our providers. Must present proof of COVID vaccination and be free of COVID19 symptoms at time of testing in accordance with NYS guidelines.

How 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. All this provides 100% accuracy in every measurement.


Each test takes approximately 15 minutes to perform and includes a report of your results. Our equipment model utilizes a full face mask that allows normal breathing during the test vs the older models that feature a mouthpiece only. This provides the most comfortable experience to our patients, especially athletes who tend to have deeper and more prolonged respirations. For your convenience, we offer testing at each of our 4 locations: Buffalo, Amherst, East Amherst, Orchard Park.


How Much Does It Cost?


The charge for testing is $40. This service is not covered by insurance.

How Do I Prepare?


Here are the instructions for preparing for your metabolic measurement:

1) Appts are scheduled early morning. Arrive in a resting, fasted state 20 minutes early for your appt. You will need to sit quietly for this length of time before testing to ensure an accurate measurement.


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.
