Mifflin-St Jeor Resting Energy Expenditure
Mifflin-St Jeor resting energy expenditure (first-line predictive REE for adults); optionally multiplied by an activity factor for total daily energy expenditure.

Example
- Weight
- 70 kg
- Height
- 175 cm
- Age
- 40 yr
- Sex
- male
Result: REE 1599 kcal/day.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- TDEE
- Total daily expenditure = REE × activity factor: sedentary 1.2, light 1.375, moderate 1.55, very active 1.725, extra active 1.9.
What you enter
- Weight
- Height
- Age
- Sex
- Activity factor (optional, for TDEE)
How this is calculated
- Formula
- REE (kcal/day) = 10 × weight(kg) + 6.25 × height(cm) − 5 × age(yr) + s, where s = +5 (male) / −161 (female).
