Basal Metabolic Rate (BMR) Calculator
This calculator estimates your Basal Metabolic Rate (BMR)—the number of calories your body burns at rest to maintain vital functions like breathing, circulation, and cell production. It’s a key component in determining daily energy needs and tailoring dietary or fitness goals.
Formula Used:
Mifflin-St Jeor Equation
- Men: BMR = 10 × weight (kg) + 6.25 × height (cm) − 5 × age (years) + 5
- Women: BMR = 10 × weight (kg) + 6.25 × height (cm) − 5 × age (years) − 161
Use Case:
BMR is used as a baseline to calculate Total Daily Energy Expenditure (TDEE) by multiplying with an activity factor.
