How Many Calories Does My Body Burn ?

Ever catch yourself wondering….. How many calories does my body burns at rest?

Perhaps you’ve looked at the calories displayed on the cardio machines at the gym, or used an online calculator to guesstimate how hard your body is working? The average adult overestimates the number of calories they think they are burning and most equations that calculate the calories burned are 20-30% inaccurate, if not more. Healthcare providers frequently use equations, such as Harrison-Benedict and Mifflin St. Jeor, to estimate calories burned.

Knowing how many calories your body burns at rest—also called your Resting Metabolic Rate (RMR)—is super helpful if you’re trying to:

  • Lose weight: Knowing your RMR helps you set a realistic nutrition and movement plan, ensuring you are supporting your body and health target.

  • Gain muscle: If you’re looking to build muscle, knowing your RMR helps you support that as well.

  • Maintenance: It’s also key if you just want to maintain your current weight without undereating or overeating.

Evexia Medical recently introduced a new high-tech Metabolic Breath Analysis (MBA) system to our practice that uses indirect calorimetry to measure oxygen consumption (VO₂) and carbon dioxide production (VCO₂) while you breathe. This test measures your Resting Metabolic Rate (RMR), meaning how many calories your body burns at rest. Oxygen is directly linked to how your body burns calories, and this test provides the most accurate measurement of your metabolism—far more precise than online calculators or estimates. The name reflects the test’s ability to analyze the lungs, heart and cells involved in oxygen absorption, transfer and utilization.

This state-of-the-art equipment gives our healthcare team the most accurate method for measuring RMR which in turn helps you understand your body’s energy needs and make more informed decisions about your diet and exercise habits.

Key Features:

  1. Breath-by-breath Analysis:
    Our test provides real-time data on how your body is utilizing energy, both at rest and during exercise. This allows it to track how your aerobic system is functioning and how well you’re burning fats and carbohydrates during different physical activities.
  2. Detailed Metabolic Insights:
    Our test gives a breakdown of how much energy is coming from fat versus carbohydrates based on your respiratory quotient (RQ). This can be valuable for athletes, weight loss programs, and health assessments.
  3. Personalized Data:
    Our test offers individualized data that can help customize nutrition plans. It takes the guessing factor out of the health plan. For example, it can help optimize performance by understanding how their bodies use different fuel sources during exercise, or it can help those aiming to lose weight by assessing their resting metabolic rate more accurately.
  4. Comprehensive Health Assessment:
    Our test also provides insights into heart, lung and cell health at any given moment. It can be used as a diagnostic tool to identify factors that play a role in your metabolism and help your doctor guide your treatment.

What to expect During the Test: You will wear a mask that fits around your mouth and nose with straps around to the back of your head and neck. You will be asked to sit comfortably in a chair and breathe normally for approximately 10 minutes. Your Doctor will be with you throughout the test.
