What is the most accurate BMR calculator?
The Mifflin-St Jeor equation is widely considered by clinical dietitians and researchers to be the most accurate predictive formula for calculating Basal Metabolic Rate (BMR) under standard conditions. Developed to replace older equations, it accounts for age, gender, height, and total body weight with a higher degree of precision for contemporary populations. While indirect calorimetry remains the absolute gold standard for measuring metabolic rate in a clinical laboratory setting, the Mifflin-St Jeor formula offers the most reliable mathematical estimation for everyday use.
