BMR Explained: How Your Body Burns Calories at Rest

Your Basal Metabolic Rate (BMR) represents the number of calories your body needs to accomplish its most basic, life-sustaining functions—like breathing, circulating blood, and cellular growth.

How to Calculate BMR

DisplayMyBMI uses the Mifflin-St Jeor equation, widely considered the most accurate formula for modern populations. It factors in your: * Weight * Height * Age * Biological Sex

Using BMR for Your Goals

Once you know your BMR, you multiply it by an "activity factor" (from sedentary to highly active) to find your Total Daily Energy Expenditure (TDEE). * To lose weight, eat below your TDEE. * To gain muscle, eat slightly above your TDEE. * To maintain, match your TDEE.
