Answer :
To calculate the Daily Recommended Intake (DRI) for protein, we follow these steps:
1. Convert Weight from Pounds to Kilograms:
We start by converting the weight from pounds to kilograms since protein needs are often given per kilogram of body weight. The conversion factor is 1 pound = 0.453592 kilograms.
For a weight of 218 pounds:
[tex]\[
218 \text{ pounds} \times 0.453592 = 98.88 \text{ kg (approximately)}
\][/tex]
2. Calculate Protein Needs in Grams:
The general guideline for protein intake is 0.8 grams of protein per kilogram of body weight. This means that for each kilogram you weigh, you need 0.8 grams of protein.
Using the weight in kilograms calculated:
[tex]\[
98.88 \text{ kg} \times 0.8 \text{ grams/kg} = 79.1 \text{ grams (approximately)}
\][/tex]
Thus, the DRI for protein for a male weighing 218 pounds is approximately 79 grams. The correct option from the choices provided is 79 grams.
