How to calculate BMR
This BMR calculator uses the Mifflin-St Jeor equation, which is one of the most accurate formulas for estimating basal metabolic rate based on gender, age, height, and weight.
Why BMR matters
Understanding your BMR helps you plan calorie intake for weight loss, maintenance, or muscle gain. It is the foundation for calculating daily calorie needs.
