What Is Basal Metabolic Rate (BMR)?
Your Basal Metabolic Rate (BMR) is the number of calories your body requires to maintain basic physiological functions while at complete rest — breathing, circulation, cell production, and temperature regulation. BMR accounts for roughly 60–70% of total daily calorie expenditure.
BMR Formulas
Mifflin-St Jeor (Most Accurate)
Men: BMR = (10 × weight kg) + (6.25 × height cm) − (5 × age) + 5
Women: BMR = (10 × weight kg) + (6.25 × height cm) − (5 × age) − 161
Harris-Benedict (Revised, 1984)
Men: BMR = (13.397 × weight kg) + (4.799 × height cm) − (5.677 × age) + 88.362
Women: BMR = (9.247 × weight kg) + (3.098 × height cm) − (4.330 × age) + 447.593
BMR vs TDEE
BMR is your calorie need at rest. To find your actual daily calorie need, multiply BMR by your activity factor to get TDEE (Total Daily Energy Expenditure). Eating below BMR for extended periods can slow your metabolism and cause muscle loss.
Factors Affecting BMR
- Age: BMR decreases roughly 2% per decade after 20
- Muscle mass: More muscle = higher BMR
- Gender: Men typically have 5–10% higher BMR due to more muscle mass
- Hormones: Thyroid disorders can significantly raise or lower BMR
- Temperature: Cold environments slightly increase BMR
