Total Energy Expenditure

$"TDEE" = BMR("female", "w" , "h" , "a" ) * ActivityLevel("moderate")$

$(a) "Age"$

$(w) "Weight"$

$(h) "Height"$

$(g) "Gender"$

$(A)"Activity Level"$

The Math / Science

The Total Energy Expenditure formula is as follows:

TDEE = BMR * AL-Factor

where:

TDEE = Total Daily Energy Expended
BMR = Basal Metabolic Rate
AL-Factor = Activity Level Factor

The Activity Level Factor is as follows:

sedentary: 1.2
light: 1.275
moderate: 1.55
very active: 1.725
extremely active: 1.9

The Base Metabolic Rate (BMR) formula computes the daily calories consumed by a person at rest based on their gender (g), age (a), weight(w) and height (h). The formula is based on the Mifflin St Jeor equation.
