For Ladies
BMR = 9.247W + 3.098H – 4.330A + 447.593
Mifflin-St Jeor Equation
A lot of the BMR calculators additionally depend on the Mifflin-St Jeor Equation. Right here is the components:
For Males
BMR = 10W + 6.25 H – 5A + 5
For Ladies
BMR = 10W + 6.25 H – 5A – 161
In each the formulation given above, W is physique weight (kg), H is the peak (cm), A is age, and F is physique fats (%)
