Harris-Benedict formula
Nutritionist Pro uses the Harris-Benedict formula to determine caloric needs based on a client's age, height, weight, and sex.
A = Age
W = Weight in kg
H = Height in cm
BEE = Basal Energy Expenditure
Males BEE = 66.4 + 13.7(W) + 5(H) - 6.8(A)
Females BEE = 655 + 9.6(W) + 1.8 (H) - 4.7(A)
note
If your client is 125 percent of their ideal body weight, the following adjustment is automatically made.
ABW = Actual Body Weight
IBW = Ideal Body Weight
(ABW - IBW) x 0.25 + IBW
note
If your client is under 18 years of age, caloric needs are determined using an Average Energy Allowance (AEA) per kilogram*
| Age | AEA | |
|---|---|---|
| Infant | 0.0 , 0.5 | 108 |
| 0.6 , 1.0 | 98 | |
| Children | 1 , 3 | 102 |
| 4 , 6 | 90 | |
| 7 , 10 | 70 | |
| Males | 11 , 14 | 55 |
| 15 , 17 | 45 | |
| Females | 11 , 14 | 47 |
| 15 , 17 | 40 |
