Metabolic & VO2 Max Testing in New York

What is metabolic testing?

Metabolic testing is a simple technology that allows your physician to test your body’s metabolic function, or how quickly it turns food into energy. This is an important tool for patients who want to lose weight, determine exactly how many calories they require per day, or to help assist in overall health improvement goals. Learn more about metabolic testing at Performance Health in NYC & Pearl River below, or schedule a consultation today.

How does metabolic testing work?

At Performance Health, we use the latest medical technologies for metabolic testing. KORR™ Medical Technologies makes it possible for physicians to obtain a precise reading of a patient’s resting metabolic rate (RMR), considered by many to be the new “vital sign” for the treatment of obesity. KORR™ puts state-of-the-art tools into the hands of our Performance Health fitness trainers and physical therapists. After testing, our physicians interpret the results for patients in a way that is informative and helps you reach your fitness and health goals.

Why is metabolic testing used?

Metabolic testing is a great tool to help your physician not only establish a baseline for your health, but to track your body’s progress over time as you move toward a healthier weight and lifestyle. Some of the most common reasons for using metabolic testing are outlined below:

Metabolic Testing to Detect a “Slow” Metabolism

Sometimes, metabolic testing is used during weight loss counseling to show a patient that they have a “normal” metabolism, rather than a “slow” one. Many patients who are overweight or obese tend to believe that they have a “slower metabolism” that is preventing their weight loss. Taking a physician-monitored measurement removes the thought that weight loss is impossible, which can be encouraging for patients trying to lose weight and improve their lifestyle.

Metabolic Testing to Maintain Weight Loss

Metabolic testing can also help to stabilize a patient’s weight loss. Despite the weight loss method, a patient’s resting metabolic rate, or RMR, decreases after they have shed some weight. This makes it easy for a patient’s weight to return after the diet phase has ended. Unfortunately, it can even happen when preventative measures are taken. However, the important part of long-term weight loss is to continue the new, healthy eating and exercise pattern, because, within about six months, a patient’s RMR usually returns to the predicted level. This means that you may experience a “plateau” phase, but eventually, you will survive this phase and hit your weight loss goal!

Metabolic Testing to Detect and Diagnose Hypometabolism

In some cases, a patient might have a medical condition that causes what is known as “clinically low” metabolism or hypometabolism. This means they may need to visit a doctor for a diagnosis as well as treatment of any underlying issues before they can successfully lose weight.

Metabolic Testing to Assess Metabolism After Weight Loss

During any kind of diet, your body will respond, especially when using extreme diets or undergoing surgery (bariatric surgery). During this time, it is important to keep track of the body’s adjustments to see the effects of your treatment and to make any needed adjustments along the way.

How should I prepare for metabolic testing?

There are a number of activities that can influence metabolic rate and should be avoided before testing:

  • Do not eat or drink during the hours leading up to testing. If you are diabetic or feeling dehydrated, eat or drink water only as needed.
  • Avoid exercise or physical labor in the hours before the test.
  • Take your medications as prescribed unless directed otherwise by your doctor.
  • Do not drink caffeine. Studies suggest that caffeine can raise RMR at a rate, which can skew the results of your testing.

What is RMR?

Your metabolic rate, or the rate that your body converts food to energy, is similar to your RMR, or your resting metabolic rate. The difference is that your resting metabolic rate calculates the rate that your body converts food into energy while you are at rest instead of during a typical day (including exercise and movement). An RMR test can show a physician and patient the amount of calories they usually burn while at rest, which can help determine an effective diet or exercise plan.
