Frequently Asked Questions
What is BMR?
Basal Metabolic Rate (BMR) is the number of calories your body needs to accomplish its most basic (basal) life-sustaining functions, such as breathing and circulation, while at rest.
How accurate is this?
We use the Mifflin-St Jeor equation, which is currently considered the most accurate formula for predicting BMR in healthy adults.
