BMR Calculator – FAQs

What is BMR?

+

Basal Metabolic Rate is the number of calories your body burns at complete rest to keep vital functions running, such as breathing, circulation, and cell production.

How is BMR different from TDEE?

+

BMR is your calorie burn at rest. TDEE (Total Daily Energy Expenditure) multiplies your BMR by an activity factor to estimate the total calories you burn in a day, including movement and exercise.

Which formula does this calculator use?

+

It uses the Mifflin-St Jeor equation, which is considered one of the most accurate predictive formulas for estimating resting metabolic rate.
