Calculate your Basal Metabolic Rate - the calories your body burns at rest.
BMR is the number of calories your body needs to maintain basic functions like breathing, circulation, and cell production while at complete rest. TDEE (Total Daily Energy Expenditure) accounts for your activity level on top of BMR.
This calculator uses the Mifflin-St Jeor equation, which is considered the most accurate for estimating BMR.
