RMR Resting Metabolic Rate

What are the benefits?

Purpose: The Resting Metabolic Rate (RMR) test is performed to estimate the amount of energy that your body burns in one day.

Why is this important: Whether your goal is to lose, gain, or maintain your weight, this information is extremely valuable for designing a personalized weight management program. Knowing the amount of energy you use at rest will help you better understand the amount of energy you need from food.

Your resting metabolic rate is influenced by your age, gender, the amount of body fat and muscle you have, the amount of exercise you do, your ethnicity, as well as by a number of environmental factors like smoking and climate. Two people with the same weight and height can have very different metabolic rates and energy (caloric) needs. 

What happens during the appointment?

Description: During the test you will be lying supine on a bed or chair. You should remain still, relaxed and as comfortable as possible without falling asleep. The testing staff will monitor you during the entire test to ensure you stay awake and should you need assistance. 

To the best of our knowledge, there are no known health risks associated with the RMR test. It may also feel warm or cold while the test is in session. The testing staff will provide blankets if desired. 

Your Responsibilities: The results of the test may be inaccurate if pre-test procedures are not properly followed. The accuracy of your results can also be affected by certain medications, medical conditions, acute infections and, for females, pregnancy, breast feeding and menstruation. You should let the testing staff know prior to the test if any of these apply, including the use of non-prescription medications. You should immediately report any unusual feelings that are of concern to the test staff during the test. 

 What is the test protocol?

Prior to your RMR test, there are a few important things to note:

• You must complete a 12 hour fast overnight, prior to your RMR test. e.g. if your appointment is at 8am, you must only drink water after 8pm the evening before.

• You must not consume alcohol or caffeine 12 hours prior to the test.

• You must avoid moderate and vigorous exercise at least 24 hours prior to the test.

• Your commute should be relatively stress-free. Avoid brisk walking, running or taking a lot of stairs.

• Failure to meet these standards may result in an inaccurate result.

• Attire for the test: No specific attire is required.
