Calorie Calculator Notes

  • Mifflin-St Jeor Equation

    The Mifflin-St Jeor Equation is one of the most commonly used formulas for calculating Basal Metabolic Rate (BMR) and total daily caloric needs.

    It estimates how many calories your body burns just to stay alive (Breathing, Heartbeat, etc.) base on;

    • Weight
    • Height
    • Age
    • Gender

    Formulas used in the Mifflin-St Jeor Equation;

    Men:BMR=
    (10 x weight in kg)+
    (6.25 x height in cm)+
    (5 x age in years)+
    5*
    Women:BMR=
    (10 x weight in kg)+
    (6.25 x height in cm)+
    (5 x age in years)-
    161*

    *Note:

    Men Tend to have slightly higher muscle mass, which burns more calories at rest

    Women historically have more body fat percentage, which is less metabolically active

    These constants were from the original study when the equation was developed. The average baseline represented the difference between male and female metabolism in the study participants. Therefore, this is a very rough baseline (as are all equations regarding metabolic calculations) and should be treated as such when using calorie calculators
