About BMR & TDEE

Your Basal Metabolic Rate (BMR) is the energy your body burns at complete rest to keep vital functions running. Total Daily Energy Expenditure (TDEE) multiplies your BMR by an activity factor to estimate the calories you burn in a typical day. Eat around your TDEE to maintain weight, less to lose, more to gain. We use the Mifflin–St Jeor equation, the most accurate for the general population.
