What is TDEE?

Your Total Daily Energy Expenditure (TDEE) is the total number of calories your body burns every 24 hours — resting, digesting, moving, and exercising. It is the most important number in nutrition, because everything else follows from it.

This calculator uses the Mifflin-St Jeor equation — the most validated BMR formula in peer-reviewed research — then multiplies by a scientifically established activity factor to produce your TDEE. The rule is simple: eat below your TDEE to lose fat, match it to maintain, exceed it to grow.
