What is BMR used for?

BMR is the baseline used to calculate total daily energy expenditure (TDEE) by factoring in activity level — it's a starting point for calorie and weight-management planning.

How accurate is this estimate?

The Mifflin-St Jeor equation is considered one of the more accurate prediction formulas for the general population, but individual metabolism can vary.
