Fit3D uses the Mifflin St. Jeor formula to calculate BMR (Basal Metabolic Rate.)
Fit3D uses the Mifflin St. Jeor formula to calculate BMR. BMR is the amount of energy expended while at rest in a neutrally temperate environment.
There are multiple formulas used to calculate BMR. Nowadays, the Mifflin-St Jeor equation is believed to give the most accurate result and it is what we use in this calculator.
This BMR formula is as follows:
BMR = (10 * weight / 1kg + 6.25 * height / 1cm - 5 * age / 1 year + s) kcal / day, where s is +5 for males and -161 for females.
