Formula Used in “EER Calculator — Estimated Energy Requirement”
The Estimated Energy Requirement (EER) is calculated using the following standard formula:
EER = (kcal/day) = 100 + (0.7 × age) + (9.6 × weight in kg) + (1.8 × height in cm) – (4.7 × gender factor)
In LaTeX-style notation, the formula can be expressed as:
EER = 100 + 0.7A + 9.6W + 1.8H – 4.7G
Where:
Step-by-Step Breakdown of the Formula
- A: Age of the individual in years.
- W: Weight of the individual in kilograms (kg).
- H: Height of the individual in centimeters (cm).
- G: Gender factor based on the individual’s gender:
- Male: 1
- Female: 0
Example Calculation
Let’s calculate the Estimated Energy Requirement for a 25-year-old male who weighs 70 kg and is 175 cm tall. We will use the standard values in the formula:
| Variable | Value |
|---|---|
| Age (A) | 25 |
| Weight (W) | 70 kg |
| Height (H) | 175 cm |
| Gender Factor (G) | 1 (Male) |
Now we will substitute these values into the formula:
EER = 100 + (0.7 × 25) + (9.6 × 70) + (1.8 × 175) – (4.7 × 1)
Calculating each component:
- 100
- 0.7 × 25 = 17.5
- 9.6 × 70 = 672
- 1.8 × 175 = 315
- 4.7 × 1 = 4.7
Now, we will sum all the values:
EER = 100 + 17.5 + 672 + 315 – 4.7 = 1099.8 kcal/day
Final Output
The Estimated Energy Requirement for a 25-year-old male weighing 70 kg and with a height of 175 cm is approximately 1100 kcal/day.
This result can aid in determining the correct caloric intake needed for various lifestyle choices and health goals. For further reading, please refer to authoritative sources on nutrition and public health guidelines.
