- Resting energy need
- kcal/day
- Maintenance energy need at this activity
- kcal/day
- Protein reference value for adults (EFSA)
- g/day
- Protein range for people who train regularly (ISSN)
- g/day
How do we calculate?
We estimate the resting energy need with the Mifflin–St Jeor equation. The maintenance value multiplies this by the physical activity level: we use the EFSA values 1.4, 1.6, 1.8 and 2.0. For protein we show the EFSA reference value for adults (0.83 g/kg) and the ISSN range for people who train (1.4–2.0 g/kg).
What is it not for?
The result is an estimate, and your individual value can differ. The calculator is for adults and gives no weight-loss target. In the case of illness, medication, pregnancy, breastfeeding or an eating disorder, get professional care.
