A useful range, not a magic number
The Mifflin–St Jeor equation estimates resting energy, while an activity multiplier moves it toward a maintenance range. The tool therefore shows a central estimate and modest scenarios instead of one precise target.
How to use it
- 1Enter age, height, weight, and formula setting.
- 2Do not overstate your everyday activity.
- 3Compare the range with real trends over several weeks.
How should you read it?
The maintenance result is a starting hypothesis. Weight, sleep, hunger, and training performance can guide small adjustments; the calculation is not a diet prescription.
Keep the limits in view
Activity multipliers and portion estimates are uncertain. Seek professional help for pregnancy, kidney disease, age under 18, or clinical nutrition needs.
