Understanding TDEE and BMR
Your Basal Metabolic Rate (BMR) represents the number of calories your body burns at complete rest to maintain vital functions like breathing, circulation, and cell production. Total Daily Energy Expenditure (TDEE) builds on your BMR by accounting for your activity level, giving you the total calories you burn each day. Understanding these numbers is fundamental for any weight management goal. Whether you're trying to lose fat, build muscle, or maintain your current weight, knowing your TDEE allows you to create an appropriate calorie target. This calculator uses the Mifflin-St Jeor equation, which research has shown to be the most accurate predictor of metabolic rate. By inputting your age, gender, height, weight, and activity level, you'll receive personalized calorie recommendations that account for your unique physiology and lifestyle.
