Understanding the TDEE Calculator
Total Daily Energy Expenditure (TDEE) is the total number of calories you burn in a day, including everything from breathing to exercise. It is the single most useful number for managing your weight, because every diet goal — cutting, maintaining, or bulking — is defined relative to your TDEE.
The components of TDEE
TDEE combines your basal metabolic rate (around 60–70% of the total), the energy used to digest food, calories burned in deliberate exercise, and the often-overlooked calories from everyday movement like walking and fidgeting. Because daily movement varies so much between people, two individuals of the same size can have meaningfully different TDEEs.
Using TDEE to hit your goal
Once you know your TDEE, eating that amount maintains your weight, eating below it drives fat loss, and eating above it supports muscle gain. Pairing your calorie target with adequate protein and resistance training helps ensure that weight lost is fat and weight gained is muscle, rather than the reverse.
Tips & things to know
- •Everyday non-exercise movement (NEAT) can swing your TDEE significantly.
- •Recalculate after notable weight changes.
- •Combine your calorie target with protein and training for better body composition.
