– The estimate energy requirement for boys 9- 18 years:

88.5 – (61.9 x age [yr] + (PA* x 26.7 x wt [kg]) + (903 x ht[m]) +25

– The estimate energy requirement for women:

354 – (6.91 x age [y]) + (PA* x 9.36 x wt [kg]) + 726 x ht [m]

– The estimate energy requirement for men:

662 – (9.53 x age [y]) + (PA* x 15.91 x wt [kg]) + 539.6 x ht [m]
