How is BMR calculated?
This calculator uses the
Mifflin St Jeor equation.
For men:
BMR = (10 weight in kg)
+ (6.25 height in cm)
- (5 age)
+ 5
For women:
BMR = (10 weight in kg)
+ (6.25 height in cm)
- (5 age)
- 161
Estimated daily calorie needs are calculated
by multiplying BMR by an activity factor.
Important:
BMR and daily calorie calculations are
estimates. Actual energy requirements can
vary with body composition, health,
pregnancy, medications, training level and
other individual factors. This calculator
is intended for general informational use
by adults and is not a medical or dietary
prescription.
