Your estimated BMR
This is estimated resting energy, not your full daily calorie need.
What BMR means
Basal metabolic rate estimates the energy needed for essential functions at rest. It excludes normal movement, training, and digestion, so it should not be used as a daily eating target.
Method and limits
FitCalc uses the same Mifflin–St Jeor equation as its TDEE, Macro, and Maintenance calculators. It is a population estimate; individual needs can differ.
