Estimate basal energy expenditure using the Harris-Benedict equations.

For men, the B.E.E. =
66.5 + (13.75 x kg) + (5.003 x cm) - (6.775 x age)

For women, the B.E.E. =
655.1 + (9.563 x kg) + (1.850 x cm) - (4.676 x age)

Total Caloric Requirements equal the B.E.E. multiplied by the sum of the stress and activity factors. Stress plus activity factors range from 1.2 to over 2.
