Frequently asked questions
What is TDEE?
Total Daily Energy Expenditure, the calories you burn per day including activity. Eating at your TDEE roughly maintains weight; below it tends toward loss, above it toward gain.
How accurate is this estimate?
It uses the well-regarded Mifflin-St Jeor equation, but individual metabolism varies. It's an informational estimate, not medical or dietary advice.
How many calories to lose weight?
A common approach is a moderate deficit (the tool shows roughly 500 kcal below maintenance), but consult a professional for a plan that suits you.
