Understanding BMR: Your Body’s Energy Foundation
Basal Metabolic Rate (BMR) represents the minimum number of calories your body requires to maintain essential physiological functions while at complete rest. This includes vital processes such as breathing, circulation, cell production, nutrient processing, and protein synthesis.
🔥 What is BMR?
BMR accounts for 60-75% of your total daily energy expenditure. It’s the energy your body burns to keep you alive, even when you’re sleeping. Understanding your BMR is crucial for effective weight management and fitness planning.
📊 How BMR is Calculated
Our calculator uses three scientifically proven formulas: Mifflin-St Jeor (most accurate for general population), Harris-Benedict (revised version), and Katch-McArdle (for those with known body fat percentage).
🎯 Why BMR Matters
Knowing your BMR helps determine your Total Daily Energy Expenditure (TDEE), enabling precise calorie planning for weight loss, muscle gain, or maintenance. It’s the foundation of all nutrition and fitness strategies.

Frequently Asked Questions About BMR
What factors affect BMR?
BMR is influenced by age, gender, weight, height, body composition, genetics, hormones, and environmental temperature. Men typically have higher BMRs than women due to greater muscle mass.
How often should I recalculate my BMR?
Recalculate your BMR every 4-6 weeks if you’re actively trying to change your body composition, or every 3-6 months for maintenance. Significant weight changes warrant immediate recalculation.
Is BMR the same as RMR?
BMR and RMR (Resting Metabolic Rate) are similar but not identical. BMR is measured under strict conditions after 12 hours of fasting, while RMR is more practical and typically 10-20% higher than BMR.
Can I increase my BMR?
Yes! Building muscle mass through strength training is the most effective way to increase BMR. Muscle tissue burns more calories at rest than fat tissue. Adequate protein intake and proper sleep also support healthy metabolism.
