Calculate your Resting Metabolic Rate and discover how many calories your body burns at rest
Resting Metabolic Rate (RMR) is the number of calories your body burns while at rest in a non-fasting state. It accounts for about 60-75% of your total daily energy expenditure and includes the energy needed for vital functions like breathing, circulation, and cellular metabolism.
RMR is typically 10% higher than Basal Metabolic Rate (BMR) because it's measured under less restrictive conditions. While BMR requires fasting and complete rest in a controlled environment, RMR can be measured more practically in everyday settings.
Muscle tissue burns more calories at rest than fat tissue
Proper hydration is essential for optimal metabolic function
Protein has a higher thermic effect and supports muscle maintenance
Poor sleep can negatively impact your metabolic rate
Severe calorie restriction can slow down your metabolism
Both cardio and strength training can boost your metabolism
BMR is measured under very strict conditions (fasting, complete rest, controlled environment), while RMR is measured under more relaxed conditions. RMR is typically 10% higher than BMR and is more practical for everyday calculations.
This calculator uses the Mifflin-St Jeor equation, which is considered one of the most accurate formulas for estimating metabolic rate. However, individual variations can occur due to genetics, body composition, and health conditions.
Yes! Building muscle mass through strength training is one of the most effective ways to increase RMR. Additionally, staying active, eating enough protein, getting quality sleep, and staying hydrated all support a healthy metabolism.
RMR naturally decreases with age and is influenced by factors like body composition, genetics, and hormones. Women typically have lower RMR than men due to lower muscle mass. Very low-calorie diets can also reduce RMR.
No, your RMR is just your resting metabolic rate. You should eat based on your TDEE (Total Daily Energy Expenditure), which accounts for all daily activities. Eating only your RMR would create too large a deficit.
Yes, muscle tissue burns approximately 6 calories per pound per day at rest, while fat burns about 2 calories per pound per day. This is why building muscle can help increase your overall metabolic rate.
Recalculate your RMR whenever you experience significant weight changes (more than 5-10 pounds), change your activity level, or every 3-6 months to ensure your calorie targets remain accurate.
While no food dramatically increases metabolism, protein has the highest thermic effect (20-30% of calories burned during digestion), followed by carbs (5-10%) and fats (0-3%). Spicy foods and caffeine may provide small, temporary increases.
