Abstract
To devise a simple and accurate formula for calculating the basal energy needs of individuals in various age groups, an attempt was made to simplify and optimize Harris & Benedict's method along with the WHO/FAO/UNU formula using a computer program. Initially, a preliminary structure was determined for the proposed simplified formula. Subsequently, the coefficients of this formula were determined by simulating two million individuals using a computer program and analyzing their basal energy requirements using the Harris-Benedict and WHO/FAO/UNU formulas. The formula was subsequently tested on 452 real male and female subjects aged 3–80 years. Results showed no significant difference in the values calculated by the old and new methods, and therefore confirmed the accuracy of the new formula.
