Answer :
The correct option is b. Based on this information, she should consume at least 91 g of protein daily.
To determine the minimum amount of protein Maggie should consume daily, we can use the general guideline for protein intake for athletes, which is 1.2 to 2.0 grams of protein per kilogram of body weight per day. Since Maggie is an athlete who performs moderate-intensity physical activity, we will use the lower end of the range, which is 1.2 grams per kilogram.
Maggie weighs 72 kg, so we calculate her minimum daily protein intake as follows:
[tex]\[ \text{Minimum daily protein intake} = 72 \, \text{kg} \times 1.2 \, \text{g/kg} \] \[ \text{Minimum daily protein intake} = 86.4 \, \text{g} \][/tex]
However, this is a rough estimate, and it is common practice to round to the nearest whole number to make the recommendation more practical. Therefore, Maggie should consume at least 86 g of protein daily.
Looking at the options provided, we see that:
a. 101 g is more than necessary.
b. 91 g is slightly more than the calculated 86 g, which provides a margin for individual variability and dietary preferences.
c. 72 g is equal to Maggie's body weight in grams, which is not the correct method to calculate protein needs.
d. 58 g is less than the calculated minimum requirement.
Thus, option b. 91 g of protein daily is the most appropriate choice, as it is the closest to the calculated minimum requirement while also providing a small buffer above the estimated need.
Maggie should consume at least 1.2 grams of protein per kilogram of body weight since she is an athlete engaging in moderate-intensity physical activity. Consequently, for her weight of 72 kg, the calculation results in at least 86.4 grams, with the closest provided answer being 91 grams daily. So the correct option is b. 91.
Maggie is an athlete who performs moderate-intensity physical activity and weighs 72 kg. To determine the minimum amount of protein Maggie should consume daily, we can use the recommended intake for athletes doing moderate to intense training, which is between 1.2 to 2.0 grams of protein per kilogram of body weight. Therefore, the lowest recommended intake for her would be 1.2 grams per kilogram:
72 kg imes 1.2 g/kg = 86.4 g of protein per day
Looking at the answer choices, the closest to this calculation is option b. 91, which indicates that she may need a bit more than the minimum depending on other factors such as the exact intensity of her workouts or overall diet.
However, as the question asks for 'at least' the amount of protein she should consume, the correct answer from the choices provided would be: 91 g of protein daily. So the correct option is b. 91.
