Calculate your Basal Metabolic Rate (BMR) using the Mifflin-St Jeor equation to estimate how many calories your body burns at rest.

What is BMR?

Basal Metabolic Rate (BMR) represents the number of calories your body needs to maintain basic life functions like breathing, organ function, and cell production while at complete rest.

Knowing your BMR helps you understand your daily calorie needs and create accurate diet, weight loss, and fitness plans.
