BMR Calculator
Calculate your Basal Metabolic Rate - the calories you burn at rest
--
calories/day
This is the number of calories your body burns at rest to maintain vital functions like breathing, circulation, and cell production.
Daily Calorie Needs by Activity Level
Understanding Your BMR
- BMR accounts for 60-75% of your total daily energy expenditure
- Muscle burns more calories than fat, even at rest
- BMR naturally decreases with age (about 2% per decade after 20)
- Never eat below your BMR - this can slow your metabolism
BMR calculations are estimates. Individual metabolism varies based on genetics, hormones, body composition, and other factors. Consult a healthcare professional for personalized advice.
