Basal Metabolic Rate (BMR) is the minimum number of calories your body needs to sustain vital functions like breathing, circulation, and cell production while completely at rest.
How BMR Is Calculated
The Mifflin-St Jeor equation (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
BMR vs. TDEE
BMR accounts for about 60–70% of total daily energy expenditure (TDEE). TDEE adds your physical activity and thermic effect of food on top of BMR.
