A foundation for calorie targets

A foundation for calorie targets

Combine your measured resting calorie burn with your activity level and goals to estimate your daily calorie needs.

RMR
After the test

A calorie number is only useful if someone builds the plan around it.

Your RMR is the floor everything else sits on. Put it next to your activity level and your goals, and Prefusion Health can turn it into what you eat.

01
Your resting calorie baseline
The energy your body uses at rest, the starting point for estimating your total daily calorie needs.
02
Fast or slow, and by how much
Whether your metabolism runs above or below predicted, and the size of the gap.
03
What changed since last time
Metabolic rate moves with age, diet and training. A retest tells you which direction you are going.

What is an RMR test?
RMR stands for Resting Metabolic Rate. It measures how many calories your body burns at rest, the energy needed for essential functions like breathing and circulation.
How does an RMR test work?
During a Resting Metabolic Rate Test in NYC, you'll sit or lie comfortably while breathing into a small mouthpiece connected to a device that measures your oxygen consumption and carbon dioxide production. The test takes about 15 - 20 minutes, providing accurate data on your body's energy expenditure at rest.
Is RMR testing safe?
Yes, the Resting Metabolic Rate test (RMR) is completely safe, painless, and non-invasive. During the test, you simply relax and breathe normally while the device collects accurate data; no physical exertion or discomfort is involved.
How long does an RMR test take?
The entire RMR test in NYC lasts approximately 20 minutes, with 15 minutes dedicated to the actual testing. This quick, non-invasive test provides precise data on your metabolism and energy expenditure.
How should I prepare for my test?
To ensure the most accurate results, fast for at least 5 hours before your test, with no food or drinks other than water, and stay well hydrated with room temperature water. Avoid caffeine, and avoid exercise, stressful situations and vigorous activity for at least 12 hours before testing. Be well rested; the test is ideally done in the morning.
How often should I get tested?
For optimal results, we recommend testing every 3 - 6 months, or whenever you make significant changes to your diet or training plan, to track how your metabolism adapts.
What can I learn from my results?
Your results reveal your daily calorie burn at rest and metabolic efficiency, including fat vs. carb utilization. This data helps you set precise calorie goals for weight management, performance, and recovery.
