BMR (Basal Metabolic Rate)

The number of calories your body burns at complete rest to maintain basic life functions.

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.
