What Is Basal Metabolic Rate (BMR)?
Formula
Your Basal Metabolic Rate is the number of calories your body needs to maintain basic life-sustaining functions like breathing, circulation, and cell production while completely at rest.
This calculator provides results from two well-known formulas: Mifflin-St Jeor (1990) and Harris-Benedict (revised 1984). Mifflin-St Jeor is generally considered more accurate for modern populations.
Common use cases:
- Foundation for calorie planning
- Understanding resting energy expenditure
- Medical and clinical nutrition assessments
