What is a BMR Calculator?
A Basal Metabolic Rate (BMR) calculator estimates how many calories your body burns at rest over 24 hours. This energy supports basic functions such as breathing, circulation, and cell maintenance. BMR is commonly used as a starting point for estimating Total Daily Energy Expenditure (TDEE), which includes daily activities and exercise.
