FAQ

How does BMR differ from calorie needs?

The Mifflin–St Jeor equation, which is generally more accurate than the older Harris–Benedict formula.

Where is it applied?

Weight loss and diet planning — as the baseline for total daily energy expenditure.

How precise is it?

It gives an approximate integer value in kcal; individual variation exists.
