Explain about the Energy Requirements in elderly?

Based on the Benedict - Harris equation for men and women, the daily energy requirements can be calculated.

For Men: 66 t 13.7 Wt 5 H - 6.8 A

For Women: 66.5 + 9.6 W + 1.8 H - 4.7A, where W= weight (kg), H = Height (cm),

A = Age (Yrs)

For practical purposes 35 kcal/kg/day in case of hyper metabolic condition and baseline requirement of 25-30 Kcal/kg  BW/day.

In case the elderly is having pulmonary insufficiency; the fat en% (percent of energy) should be increased to 50%.

Proteins: Normally 1g/kg BW /day are the protein requirement which may be increased to 1.5 g/kg/BW/day in stress conditions. However, in case of renal and hepatic insufficiency protein intake is reduced as per condition.
