RMR Equation:
| From: | To: |
Resting Metabolic Rate (RMR) is the number of calories your body burns at rest to maintain basic physiological functions such as breathing, circulation, and cell production. It represents the minimum energy needed to keep your body functioning while at complete rest.
The calculator uses the Mifflin-St Jeor equation:
Where:
Explanation: This equation is considered one of the most accurate for estimating RMR in healthy individuals.
Details: Knowing your RMR is essential for creating effective weight management plans, whether for weight loss, maintenance, or gain. It forms the foundation for determining your total daily energy expenditure.
Tips: Enter your weight in kilograms, height in centimeters, age in years, and select your gender. For accurate results, use precise measurements.
Q1: What's the difference between RMR and BMR?
A: Basal Metabolic Rate (BMR) is measured under more restrictive conditions (complete rest, fasting, and thermoneutral environment), while RMR is measured under less strict conditions. In practice, the terms are often used interchangeably.
Q2: How accurate is this RMR calculation?
A: The Mifflin-St Jeor equation is about 80% accurate for most people. For more precise measurement, clinical tests like indirect calorimetry are recommended.
Q3: Does muscle mass affect RMR?
A: Yes, muscle tissue burns more calories at rest than fat tissue. People with higher muscle mass typically have a higher RMR.
Q4: How often does RMR change?
A: RMR changes with weight fluctuations, aging, and changes in body composition. It's recommended to recalculate every few months or after significant weight changes.
Q5: Can I increase my RMR?
A: Yes, through strength training to build muscle, adequate protein intake, proper hydration, and sufficient sleep.
