BMR
Calculator
Calculate your Basal Metabolic Rate — calories burned at rest for essential functions.
How It Works
Your BMR represents the minimum calories your body needs at rest for breathing, circulation, and cell production. It typically accounts for 60-75% of total daily energy expenditure.
Understanding Your BMR
Basal Metabolic Rate (BMR) is the calories your body burns at complete rest for vital functions like breathing, circulation, and cellular processes.
BMR calculations are estimates based on population averages. Individual metabolic rates can vary by 15-20%.
