How to read the result
BMR estimates resting energy needs, while TDEE applies an activity factor. Use the result as a planning baseline and adjust based on real-world changes over time.
FAQ
- What is the difference between BMR and TDEE?
- BMR estimates resting energy needs, while TDEE applies an activity multiplier to estimate daily total energy use.
- How should I choose an activity level?
- Pick the closest match to your typical weekly activity pattern, then adjust in practice if your real-world results differ.
- Which formula does this calculator use?
- This calculator uses the Mifflin-St Jeor equation, a common modern formula for estimating resting energy expenditure.
