What is RMR?

Your Resting Metabolic Rate (RMR) is the number of calories your body burns while awake in a normal rested state (i.e. relaxing in a comfortable chair). Your RMR is an extremely important number for planning your diet and training. Using RMR as a baseline, you can then adjust your caloric intake up or down based on your level of activity and body composition goals. Trying to shed bodyfat? Consume calories below your maintenance activity-adjusted RMR number. Want to pack on muscle? You’ll need to be consuming calories at a surplus. Whether you're refining your training, exploring fasting protocols, or seeking a deeper understanding of your body's needs, our RMR test offers the data you need to make rapid progress.

Your Resting Metabolic Rate (RMR) is the number of calories your body burns at rest just to keep you alive — powering essential functions like breathing, circulation, and cell repair. It accounts for about 70% of your total daily energy expenditure, making it the single most important number to know when trying to lose weight, build muscle, or manage long-term health.

RMR is influenced by a wide range of personal factors:

  • Age

  • Body composition

  • Hormone levels

  • Environment

  • Weight

  • Medical conditions

Because your metabolism is highly individual and constantly evolving, using generic equations to estimate your caloric needs can result in errors of up to 30–40%. That margin could be the difference between success and stagnation.

Many diets and fitness plans fail simply because they don’t start with this foundational insight. Trying to change your body without knowing your RMR is like painting with a broom — you may make progress, but you’re missing the precision that unlocks real, lasting results.

Our medical-grade RMR test gives you real data, not estimates, so you can finally take the guesswork out of your health and nutrition strategy. Establish your baseline now and see how your metabolism responds over time to training, diet, aging, and more.

FAQs

  • RMR testing measures your Resting Metabolic Rate, akin to gauging the energy needed to keep a car idling. It tells us how many calories you burn at rest, supporting vital functions like breathing, circulating blood, and cellular repair. It's a fundamental indicator of your metabolic health, crucial for understanding how your body uses energy when it's not active.

  • Your RMR accounts for about 70% of your Total Daily Energy Expenditure (TDEE). Knowing it is essential for accurately gauging your daily caloric needs. This information is critical whether you're aiming to lose weight, build muscle, or maintain your current state. It's the foundational number on which your nutrition and fitness plans should be built.

  • The test highlights how your body primarily uses energy - whether it's burning fats or carbohydrates. This insight allows you to tailor your diet to your metabolic strengths, optimizing the way you fuel your body for daily activities and workouts.

  • Akin to prepping for a medical procedure, fasting for a minimum of five hours and limiting physical activity helps ensure your body is in a true resting state. Avoid caffeine and stimulants to prevent any alterations in your metabolic rate.

  • RMR includes calories burned during low-effort activities, making it a more realistic measure of your daily caloric needs, while BMR is the bare minimum your body needs to function at rest. Think of RMR as the energy needed to power not just the engine but also the lights and radio of a car, compared to just the engine (BMR).

  • DexaFit's RMR test is significantly more accurate than formula-based estimates, which can be off by 30-40%. It's like using a high-precision measuring tool versus a rough estimate, ensuring you get an accurate understanding of your metabolic health.

  • Absolutely. By understanding your RMR, you can more effectively tailor your diet and exercise plans. It's a critical component in breaking through weight loss plateaus or efficiently building lean mass.

  • Embarking on an RMR test is like decoding your body's energy playbook. It reveals your Resting Metabolic Rate, the baseline energy your body uses for essential functions like breathing and circulating blood. But there's more – you'll also discover your Respiratory Exchange Ratio (RER), which tells you whether fats or carbs are your body's preferred fuel. Your Resting Heart Rate (RHR) unfolds the tale of your heart's efficiency, a silent yet vital aspect of overall health.

    Diving deeper, the test sheds light on your Total Daily Energy Expenditure (TDEE) – a comprehensive measure encompassing not just your RMR, but also the energy expended through physical activity and workouts. TDEE even factors in the subtle yet significant energy used in everyday non-exercise movements, known as Non-Exercise Activity Thermogenesis (NEAT). NEAT includes all the small activities you do throughout the day – walking, typing, even fidgeting – which collectively contribute to your daily calorie burn. Understanding TDEE is crucial, as it represents the total number of calories you expend daily, guiding you to make informed decisions about your diet and exercise for optimal health and wellness.

  • Lifestyle changes such as interval training can significantly boost your RMR. This type of training prevents your body from becoming too efficient at one exercise, continuously burning peak calories. Dietary adjustments, like increasing protein intake, also play a role as protein requires more energy to digest.

  • Several variables influence your metabolic rate, including age, muscle mass, hormonal balance, and overall health. Understanding these factors is key to making informed decisions about your nutrition and exercise, optimizing your metabolic efficiency.
