As race-day approaches, and in order to increase his glycogen stores and reduce the likelihood of fatigue, Anthony wants to increase the percentage of total kilocalories in his diet coming from carbohydrate. If he is eating 2500 kilocalories per day during the training period, and if he wants 60% of his kilocalories per day to come from carbohydrate, how many grams of carbohydrate should he be eating per day?

Question

Multiple Choice

1500 grams of carbohydrate per day

375 grams of carbohydrate per day
300 grams of carbohydrate per day
167 grams of carbohydrate per day

Answer 1

To find out how many grams of carbohydrate Anthony should consume, follow these steps:

1. Calculate the number of kilocalories from carbohydrates:

   • He wants 60% of 2500 kilocalories to come from carbohydrates. \[ \text{Kilocalories from carbohydrates} = \text{Total kilocalories} \times \text{Percentage of carbohydrates} \] \[ \text{Kilocalories from carbohydrates} = 2500 , \text{kcal} \times 0.60 = 1500 , \text{kcal} \]

2. Convert kilocalories from carbohydrates to grams:

   • Carbohydrates provide 4 kilocalories per gram.
   • To find the grams of carbohydrates, divide the kilocalories from carbohydrates by the number of kilocalories per gram. \[ \text{Grams of carbohydrates} = \frac{\text{Kilocalories from carbohydrates}}{\text{Kilocalories per gram of carbohydrate}} \] \[ \text{Grams of carbohydrates} = \frac{1500 , \text{kcal}}{4 , \text{kcal/g}} = 375 , \text{grams} \]

Therefore, Anthony should be eating 375 grams of carbohydrate per day.
