Question

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 carbohydrates. 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?
multiple choice
300 grams of carbohydrate per day
1500 grams of carbohydrate per day
167 grams of carbohydrate per day
375 grams of carbohydrate per day

Explanation:

Step1: Calculate kilocalories from carbohydrate

Total kilocalories per day is \(2500\). Percentage from carbohydrate is \(60\%\). So kilocalories from carbohydrate \(= 2500\times0.6=1500\) kcal.

Step2: Convert kilocalories to grams

Since \(1\) gram of carbohydrate provides \(4\) kcal. Let \(x\) be the grams of carbohydrate. Then \(4x = 1500\). Solving for \(x\), we get \(x=\frac{1500}{4}=375\) grams.

Answer:

375 grams of carbohydrate per day
