About the Calorie & TDEE Calculator
Total Daily Energy Expenditure (TDEE) is the number of calories you burn in a day. It is your basal metabolic rate (BMR) multiplied by an activity factor. Eating below your TDEE leads to weight loss, above it leads to weight gain. The results use the Mifflin-St Jeor equation, widely regarded as one of the most accurate estimates.
