Resting Metabolic Rate (RMR) Testing
Know exactly how many calories your body burns at rest. Stop guessing and start eating with confidence.
What is RMR?
Your Resting Metabolic Rate (RMR) is the number of calories your body burns at complete rest-just to keep your heart beating, lungs breathing, brain functioning, and all other vital processes running. It represents about 60-75% of your total daily calorie expenditure.
Unlike online calculators that estimate your RMR based on population averages, we measure your actual metabolic rate by analyzing the oxygen you consume and carbon dioxide you produce while at rest. This gives you precise, personalized data instead of generic formulas.
Why RMR Testing Matters
🍽️ Know How Much to Eat
Stop following generic meal plans and "1,200 calorie diets." Your RMR reveals your unique baseline, so we can calculate exactly how much you should eat for weight loss, maintenance, or performance-no guesswork involved.
⚖️ Set Realistic Calorie Targets
Online calculators can be off by 300-500 calories per day. When you're trying to lose or gain weight, that error matters. Get your real number so you can hit your goals without frustration.
🔥 Understand Your Metabolism
Learn if your metabolism is higher or lower than expected for your age, gender, and body composition. This insight helps explain why certain diets have or haven't worked for you in the past.
🎯 Optimize Cutting or Bulking
Whether you're trying to lose fat, gain muscle, or maintain performance, knowing your RMR lets us create precise intake bands. Eat enough to fuel training without overeating or undereating.
How We Test
Arrival & Setup
Arrive fasted and well-rested. We'll have you sit comfortably in a chair and relax for a few minutes while we explain the process.
Mouthpiece and Nose Clip
You'll breathe into a comfortable mouthpiece connected to our metabolic analyzer, with a nose clip ensuring all breath goes through the tube. This allows us to precisely measure your oxygen consumption and carbon dioxide production. It's completely non-invasive and comfortable.
Quiet Rest
Sit quietly and breathe normally for 10-15 minutes. You can close your eyes, relax, and let your mind wander. Some people even meditate. Just stay awake and still.
Data Collection
Our metabolic cart continuously measures your oxygen and CO₂ exchange, calculating your precise calorie burn at rest. We monitor the data to ensure we capture a valid, steady-state measurement.
Results & Recommendations
We review your RMR immediately and calculate your Total Daily Energy Expenditure (TDEE) based on your activity level. You'll leave with specific calorie and macronutrient targets for your goals.

Frequently Asked Questions
Do I really need to fast?
Yes, for best results. Eating increases your metabolic rate for several hours (called the thermic effect of food), which would make your RMR measurement artificially high. Fasting ensures we measure your true baseline.
How accurate is RMR testing?
Our metabolic cart has a ±3% margin of error, making it far more accurate than online calculators or prediction equations, which can be off by 20-30% or more.
Should I retest?
Retest after significant weight loss or gain (10+ lbs), after major diet or training changes, or every 6-12 months to ensure your calorie targets are still accurate.
