FAQ
What is BMR?
BMR (Basal Metabolic Rate) is the number of calories your body needs at complete rest to maintain basic life functions like breathing, circulation, and cell production. It typically accounts for 60-75% of total daily calories burned.
Which BMR formula is more accurate?
The Mifflin-St Jeor equation (1990) is considered more accurate than Harris-Benedict (1919) for modern populations. It typically gives results within 10% of measured BMR.
