Children with healthy body weight |
Girls 3 through 8 years: |
Estimated energy requirements (kcal/d) = 135.3 – (30.8 × age [years]) + PA × (10 × weight [kg] + 934 × height [m]) + 20, where: |
PA = 1.00 if sedentary (PAL ≥1.0 and <1.4) |
PA = 1.16 if low active (PAL ≥1.4 and <1.6) |
PA = 1.31 if active (PAL ≥1.6 and <1.9) |
PA = 1.56 if very active (PAL ≥1.9 and <2.5) |
The factor of 20 is included to account for the energy expended in tissue synthesis due to growth. |
Boys 3 through 8 years: |
Estimated energy requirements (kcal/d) = 88.5 – (61.9 × age [years]) + PA × (26.7 × weight [kg] + 903 × height [m]) + 20, where: |
PA = 1.00 if sedentary (PAL ≥1.0 and <1.4) |
PA = 1.13 if low active (PAL ≥1.4 and <1.6) |
PA = 1.26 if active (PAL ≥1.6 and <1.9) |
PA = 1.42 if very active (PAL ≥1.9 and <2.5) |
The factor of 20 is included to account for the energy expended in tissue synthesis due to growth. |
Girls 9 through 18 years: |
Estimated energy requirements (kcal/d) = 135.3 – (30.8 × age [years]) + PA × (10.0 × weight [kg] + 934 × height [m]) + 25, where: |
PA = 1.00 if sedentary (PAL ≥1.0 and <1.4) |
PA = 1.16 if low active (PAL ≥1.4 and <1.6) |
PA = 1.31 if active (PAL ≥1.6 and <1.9) |
PA = 1.56 if very active (PAL ≥1.9 and <2.5) |
The factor of 25 is included to account for the energy expended in tissue synthesis due to growth. |

Children who are overweight or obese |
Girls 3 through 18 years: |
Total energy expenditure (kcal/day) = 389 – (41.2 × age [years]) + PA × (15.0 × weight [kg] + 701.6 × height [m]), where: |
PA = 1.00 if sedentary (PAL ≥1.0 and <1.4) |
PA = 1.18 if low active (PAL ≥1.4 and <1.6) |
PA = 1.35 if active (PAL ≥1.6 and <1.9) |
PA = 1.60 if very active (PAL ≥1.9 and <2.5) |
This equation is intended to predict energy needs for weight maintenance and thus does not include a factor for the energy cost of growth. |
Boys 3 through 18 years: |
Total energy expenditure (kcal/day) = 114 – (50.9 × age [years]) + PA × (19.5 × Weight [kg] + 1161.4 × height [m]), where: |
PA = 1.00 if sedentary (PAL ≥1.0 and <1.4) |
PA = 1.12 if low active (PAL ≥1.4 and <1.6) |
PA = 1.24 if active (PAL ≥1.6 and <1.9) |
PA = 1.45 if very active (PAL ≥1.9 and <2.5) |
This equation is intended to predict energy needs for weight maintenance and thus does not include a factor for the energy cost of growth. |
