Resting Metabolic Rate (RMR) Testing

Getting the best results starts before you arrive.

‍

To ensure the test captures a true and useful picture of your physiology, we recommend a few simple preparations:

• No food or drink (except water) for 12 hours prior.
• Skip caffeine, nicotine, and intense exercise for 24 hours before testing.
• Arrive well-hydrated but avoid heavy meals or workouts on test day. Eating before your RMR test will influence the gas-exchange measurement and will result in an inaccurate test result

Resting Metabolic Rate (RMR) testing measures the calories your body burns at complete rest—your baseline energy expenditure needed to sustain vital functions. We use a comfortable gas-exchange mask to analyse your oxygen consumption and carbon dioxide production, giving a precise calculation of your resting metabolic rate, rather than a simple equation based on anthropometric variables that is often used by other assessment tools. 

- Tailored Nutrition Targets

Stop guessing your calorie needs. Get exact daily energy requirements to support weight loss, maintenance, or gain muscle mass, allowing you to optimise calorie intake around your unique metabolism.

- Efficient Weight Management

Understand how changes in body composition or activity level impact your metabolic rate—so you can adjust your nutrition and training programmes for sustainable results.

- Health & Hormonal Insights

A lower-than-expected RMR can give insights into issues such as hormonal imbalances or metabolic issues; early detection allows targeted interventions to be put in place for improved long-term health.

- Rest & Relax
‍Arrive fasted and rested, reclining in our comfortable testing rooms. You’ll wear a lightweight gas-exchange mask.

- Gas Analysis
‍We measure your oxygen intake and carbon dioxide output continuously for 15–20 minutes under resting conditions.

- Data Interpretation
‍Your metabolism is calculated from your respiratory exchange, producing an accurate kcal/day figure.

- Resting Metabolic Rate Report
‍Receive detailed data outlining resting caloric intake, calorie goals for weight loss, weight maintenance or weight gain.
