Frequently asked questions
Clear answers based on established nutrition science.
What is TDEE?
TDEE (total daily energy expenditure) is the total calories you burn in a day — at rest, through daily movement, and during exercise. It equals your maintenance calories. Use our calorie calculator to turn TDEE into a daily target for your goal.
TDEE vs BMR?
BMR is calories burned at complete rest. TDEE adds activity on top and is always higher. This tool uses the Mifflin–St Jeor equation for BMR, then applies a standard activity multiplier.
