Based on the Harris-Benedict equations:

Basal energy expenditure (BEE):

For males:

BEE = 66.67 + [13.75 x Weight (kg)] + [ 5 x Height (cm)] - [6.76 x Age (years)]

For females:

BEE = 655.1 + [9.56 x Weight (kg)] + [1.86 x Height (cm)] - [4.68 x Age (years)]

The total daily energy expenditure (TDE) is calculated taken into accounts of activity and stress factors:

TDE = BEE x activity factors x stress factors

Activity factors:

Confined to bed: 1.2

Ambulatory: 1.3

Stress factors:

Surgery: 1.2

Infection: 1.5 (from 1.4 to 1.6)

Trauma: 1.4 (from 1.3 to 1.5)

Burns: 1.8 (from 1.5 to 2.1)

The energy requirements for infants, children, and teenagers are different than those for adults and vary according to age, growth rate, and clinical or metabolic status. They are about 100 kcal/kg/day for infants, 80 to 100 kcal/kg/day for children, and 35 to 60 kcal/kg/day for teenagers.
