Formulas and calculations

 

Harris - Benedict Equation of Basal Energy Expenditure (BEE)  
Males  

BEE = 66.5  +  (13.7  x  wt in kg)  +  (5   x  height in cm)  +  (6.7  x  age in years)

Females
BEE = 655.1  +  (9.6  x   wt in kg) n +  (1.8  x  height in cm)  +  (4.6  x  age in years)
 
Calculated Caloric Requirements (CCR)
CCR  =  BEE  x  activity factor  x  stress factor
