About BMR Calculation

Your Basal Metabolic Rate (BMR) is the number of calories your body needs to accomplish its most basic life-sustaining functions, such as breathing, circulation, and cell production.

The Mifflin-St Jeor equation used here is considered the most accurate method for estimating BMR in most adults.
