BMR Summary

What is BMR?

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

This calculator uses the Mifflin–St Jeor equation, one of the most accurate methods for estimating BMR.

By adjusting activity level and goals, you can estimate calories for weight maintenance, loss, or muscle gain.
