BMR (Basal Metabolic Rate) is the number of calories your body needs at complete rest to maintain basic functions like breathing, circulation, and cell repair.

What is the difference between BMR and TDEE?

BMR is calories burned at rest. TDEE multiplies BMR by an activity factor to give total daily calorie needs.

FAQ

What is BMR?

BMR is the number of calories your body burns at complete rest to sustain vital functions — breathing, blood circulation, and cell repair.

Which formula does this calculator use?

We use the Mifflin-St Jeor equation, widely considered the most accurate formula for estimating BMR in healthy adults.

Can I eat at my BMR?

Eating at or below BMR for extended periods is not recommended. Your actual calorie needs include activity — use the TDEE calculator for a more complete estimate.
