Resting Energy and Activity Multiplier
This screen combines a resting-energy equation with an activity multiplier. Similar exercise frequency does not imply identical intensity or daily movement, so TDEE is a scenario rather than an exact expenditure measurement.

How to use this tool
Enter the equation’s sex coefficient, age, kilograms and centimetres, then choose an activity factor from 1.2 to 1.9. Adding exercise calories again can double-count activity already represented by that factor.
Results and examples
The BMR label refers to the Mifflin resting estimate; TDEE multiplies it by the chosen factor. Compare it with observations rather than treating it as a food prescription or a promised weight-loss rate.
Worked example
A 30-year-old male at 70 kg and 170 cm with factor 1.2 gives 1,617.5 × 1.2 = 1,941 kcal.
Limitations
- The equation population and activity multipliers still require specialist review.
- It is unsuitable for dietary planning in minors, pregnancy, breastfeeding or eating disorders.

Frequently asked questions
Should I add exercise calories?
Not automatically; the factor already represents activity.
Should I eat only the BMR amount?
No. A resting estimate is not a food-intake recommendation.
