Calculate Basal Metabolic Rate
BMR (Basal Metabolic Rate) is the number of calories your body burns at complete rest to maintain vital functions like breathing, circulation, and cell production. It accounts for 60-75% of your daily calorie expenditure and is crucial for understanding your body's energy needs.
BMR measures calories burned at complete rest, while TDEE (Total Daily Energy Expenditure) includes BMR plus calories burned through physical activity, digestion, and daily movements. TDEE is always higher than BMR.
BMR calculators using formulas like Mifflin-St Jeor are typically accurate within 10% for most people. For more precise measurements, indirect calorimetry testing at a medical facility can provide exact results.
Yes, BMR typically decreases with age, declining about 1-2% per decade after age 20. This is primarily due to loss of muscle mass and hormonal changes. Regular strength training can help maintain muscle mass and BMR.
Yes, you can boost BMR by building muscle through strength training, staying hydrated, getting adequate sleep, eating enough protein, and avoiding extreme calorie restriction which can slow metabolism.
