Metabolism and the RMR Test

Metabolism is the process of converting food (calories) into energy. Many factors affect a person’s metabolic rate: Weight, age, body composition, hormone levels, and gender, making it a highly unique number. The Resting Metabolic Rate (RMR) test measures the calories YOUR body burns while at rest, then produces a caloric target zone to follow in order to lose and maintain a healthy weight.

What the RMR Test Reveals

The 12-minute breathing test reveals Total Calories consumed by you on a daily basis, which consists of three numbers:
Resting Metabolic Rate: The number of calories you burn while at rest.
Lifestyle & Activity: The number of calories you burn during daily activities.
Exercise: The number of calories you would burn during 30-minutes of moderate exercise.

Your Target Caloric Zone

The test will produce a Caloric Target Zone for the purpose of:
• Weight Loss: This is the range that will allow you to lose about 1.5 to 2 lbs per week to reach your goal weight.
• Weight Maintenance: Everyone knows that keeping weight off is a major part of the weight loss battle. Once you reach your goal weight, this zone will help you make the transition to maintaining your new sustainable weight.


Facts About Body Composition

Your Metabolic Rate Test includes all of these Biomarkers.

Body Weight

It may be an obvious fitness indicator, but body weight alone doesn’t tell you everything. Measuring your weight in conjunction with other readings gives you a clearer picture of what’s going on with your body.

Skeletal Muscle

Skeletal muscle burns 22% of all calories, so it’s important to build and maintain. It’s also beneficial to your diet and exercise routine, helping to prevent rebound weight gain and avoid injury.

Body Mass Index

This indicator is calculated from your height and weight and is a measure of overall body fat. The higher the BMI, the greater the chance for possible health risks.

Body Age

This indicator is calculated using your weight, body fat percentage and skeletal muscle percentage. The resulting number reflects your body age in relation to your calendar age. You want to keep it lower if possible.

Body Fat Percentage

If you’re losing weight, tracking your body fat percentage lets you know you’re trimming the fat as opposed to losing other kinds of weight.

Visceral Fat

Visceral fat surrounds the vital organs in the abdomen. Since it cannot be seen from the outside, it often goes undetected. Excessive visceral fat may lead to high cholesterol, heart disease and type-2 diabetes.

Preparing For The Test

  • At your appointment, and prior to the test, you'll fill out a questionnaire so we can better understand your unique goals.
  • Avoid eating for 4 hours prior to testing.
  • Avoid stimulants such as caffeine (coffee, tea, chocolate, etc), over-the-counter antihistamines and some herbal remedies on the day of the test.
  • You may drink water, but avoid very cold water just prior to the test.
  • No exercise (or any workout that sustains your heart rate for a period of time) on the day of the test.
  • Try to be as rested as possible the day of the test.
  • No special clothing is needed. Wear any comfortable clothing of your choice.
  • The test is done while reclining in a chair.

During The Test

  • During the test you will recline is a comfortable position.
  • You will be given a new, clean, package-sealed mouthpiece to breathe into.
  • The air that you breathe out will go through the mouthpiece and into the metabolic analyzer to measure your metabolic rate.
  • The air that you breathe in, comes from the air in the room.
  • Lips should remain sealed around the mouthpiece.
  • A nose clip is available to ensure that all your expired air goes into the device.
  • If at any time during the test you need to take the mouthpiece out to swallow, wet your lips, or use a tissue, that's OK.
  • We encourage you to relax and close your eyes.
  • In just approximately 12-minutes your metabolic rate will be measured, and those results will be used to calculate your Target Caloric Zones to start you on the path to a healthy lifestyle.
