Metabolic Testing

Indirect Calorimetry

 

We offer state of the art Metabolic Rate Testing (Indirect Calorimetry) using the Breezing Pro. This is currently the most accurate device on the market for measuring resting metabolic rate (RMR). RMR is defined as how many calories you burn each day plus the digestion of food in a completely sedentary state. This is the gold-standard method for determining calorie needs 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. We chose these devices to better serve professional athletes, as the full face mask allows for deeper and more comfortable respirations than older and less accurate models on the market, including the Med Gem.  

 

What are the benefits of knowing your metabolic rate?

 

Understanding your metabolic rate allows your RDN to make precise recommendations unique to you, rather than using the standard equations such as the Mifflin St. Jeor, which as recently been repealed by Dr. St. Jeor with the advent of the Breezing Pro technology dispelling it's accuracy. We work with complicated cases who often have altered metabolic rates resulting from an altered state of health. This technology picks up on the increased or decreased metabolisms of these individuals with precision. You will learn 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 chronic inflammation, medical conditions, extreme athleticism, or a history of bad dieting. Please contact us if you are interested in utilizing this technology at your appointment. Knowledge is power!

How Does It Work?

 

The Breezing Pro 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 4 of our locations: Amherst, Kenmore, Buffalo, and 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.
