Replace a generic calorie calculator with a measurement of your own metabolism. Resting metabolic rate testing estimates how much energy your body uses at rest and gives you a more personal starting point for nutrition, weight-loss and performance planning.

What Is Resting Metabolic Rate?
The largest part of your daily energy use.
Resting metabolic rate, or RMR, is the energy your body uses to maintain essential functions while you are at rest. It typically represents the largest portion of daily calorie expenditure.
Online calculators estimate RMR from age, height, weight and sex. An RMR test measures oxygen consumption and carbon-dioxide production while you rest, producing an individualized estimate based on your current physiology.
What Your Results Can Support
A more informed place to start.
A more informed daily calorie target
Weight-loss or body-composition planning
Nutrition decisions during heavy training
A check on whether a generic calorie estimate is realistic for you
A baseline to pair with DXA body composition data
A structured conversation with a nutrition coach
What to Expect
Rest, breathe, and measure.
Follow the pre-test instructions so food, caffeine and recent exercise do not distort the measurement.
Rest quietly in a comfortable position while breathing through the testing equipment.
Remain relaxed and limit unnecessary movement during the measurement period.
Review the estimated resting calorie expenditure and how it fits into a broader daily-energy plan.
RMR, REE and BMR
RMR means resting metabolic rate and REE means resting energy expenditure. In fitness settings these terms describe closely related resting-energy measurements. BMR, or basal metabolic rate, is measured under stricter laboratory conditions. We lead with RMR because it is the term most people recognize, and we mention REE as an alternate name.
Best for a More Personal Plan
When a real number beats an estimate.
Clients beginning a weight-loss or recomposition program
People who have been relying on generic calorie calculators
Athletes balancing performance goals with adequate fueling
Adults pairing nutrition coaching with objective measurements
Clients tracking changes alongside DXA body composition scans
Build a Plan Around the Number
RMR is a starting point, not a prescription.
Daily activity, training, recovery, food preferences and adherence still matter. Nutrition and weight-loss coaching can combine the measurement with realistic habits, while DXA testing can provide an objective body-composition baseline.

Nutrition & Weight Loss Coaching
Turn your resting metabolic rate into a realistic calorie and habit framework you can sustain.
Your resting metabolic rate is delivered in plain language, framed as a calorie floor you can plan around. Test more than one thing and it sits alongside your body composition and aerobic results in a single, readable report.

Frequently Asked Questions
RMR testing, answered.
Does an RMR test tell me exactly how many calories to eat?
It provides an individualized estimate of resting energy use. Your total intake also depends on activity, training, goals and other personal factors.
Is RMR testing useful for weight loss?
It can improve the starting estimate used to plan calorie intake and can make nutrition coaching more specific. It does not guarantee weight loss on its own.
Why do I need to prepare for the test?
Food, caffeine, recent exercise and stress can raise short-term energy expenditure. Following the instructions helps produce a more representative resting measurement.
Can I combine RMR and DXA testing?
Yes. RMR provides resting-energy information, while DXA measures body composition. Together they offer a stronger baseline for nutrition and training decisions.
Is this a medical metabolism test?
The service is intended for fitness, wellness and nutrition planning. It does not diagnose a metabolic disorder or replace medical evaluation.
