Your BMR is the number of calories your body needs to function while at rest. This includes breathing, blood circulation, and cell production.
Science of BMR
Basal Metabolic Rate (BMR) represents the minimum amount of energy required to keep your body functioning at rest.
BMR vs TDEE
While BMR is your resting energy expenditure, TDEE (Total Daily Energy Expenditure) includes your physical activity.

Frequently Asked Questions
What is the difference between BMR and TDEE?
BMR is the calories you burn just by existing (at rest). TDEE (Total Daily Energy Expenditure) includes your BMR plus the calories you burn through daily activities and exercise.
Which formula is used for this calculator?
This tool uses the Mifflin-St Jeor equation, which is widely considered the most reliable formula for predicting resting metabolism in modern populations.
