Question

Ethan is a sophomore collegiate rugby player. The season starts in four months and he would like to gain 8 pounds of muscle in order to improve his performance. Currently, he weighs 198 pounds and consumes 3400 calories per day.

➤ Calculate the recommended daily protein intake range in grams.
How many calories from protein will be contributing to his total daily caloric intake?
Does this fall within the acceptable range?

Answer 1

To calculate the recommended daily protein intake range, convert weight from pounds to kilograms and multiply by 1.2 to 2.0 grams of protein per kilogram of body weight. Calculate the calories from protein by multiplying the protein intake by 4. This falls within the acceptable range as Ethan's current caloric intake is 3400 calories.

Step-by-step explanation:

To calculate the recommended daily protein intake range for Ethan, we'll use the range of 1.2 to 2.0 grams of protein per kilogram of body weight. First, we need to convert Ethan's weight from pounds to kilograms: 198 pounds = 89.8 kilograms. The recommended protein intake range for Ethan would be:

Lower end: 1.2 * 89.8 = 107.8 grams of protein per day

Higher end: 2.0 * 89.8 = 179.6 grams of protein per day

To calculate the calories from protein, we'll use the fact that 1 gram of protein provides 4 calories. So, if Ethan consumes 107.8 grams of protein (lower end), he would be getting 107.8 * 4 = 431.2 calories from protein. If he consumes 179.6 grams of protein (higher end), he would be getting 179.6 * 4 = 718.4 calories from protein.

This falls within the acceptable range as his current caloric intake is 3400 calories and the recommended protein intake falls between 431.2 to 718.4 calories.
