What is BMR?
Your Basal Metabolic Rate is the number of calories your body burns at complete rest — just to keep you alive. It's the foundation of your daily calorie needs.
BMR vs TDEE
BMR is rest-only. Your Total Daily Energy Expenditure (TDEE) adds the calories you burn through daily activity and exercise — shown below for each activity level.
Frequently asked questions
How is BMR calculated?
We use the Mifflin-St Jeor equation, the most accurate for the general population.
Why does BMR matter?
It's the baseline for any diet plan — eating far below it is hard to sustain.
