An athlete requires 4000 kcals. If cornflakes provide 25% of the RDA for carbohydrates per serving, how many servings are needed for the athlete to meet this requirement?

To determine how many servings of cornflakes an athlete needs to meet their carbohydrate requirement based on the provided caloric intake, it's important to first understand the composition of carbohydrates in cornflakes and their contribution to the total caloric needs.

The average carbohydrate requirement for an athlete can be calculated using the general recommendation that 45-65% of total daily calories should come from carbohydrates. For an athlete requiring 4000 kcals, this translates to approximately 1800 to 2600 kcals dedicated to carbohydrates. Given that carbohydrates provide 4 kcal per gram, this means the athlete needs about 450 to 650 grams of carbohydrates daily.

If each serving of cornflakes provides 25% of the Recommended Dietary Allowance (RDA) for carbohydrates, that RDA generally suggests about 130 grams for an average sedentary adult. Therefore, 25% of that amount from cornflakes would provide roughly 32.5 grams of carbohydrates per serving (which is 130 grams * 0.25).

To find out how many servings are necessary for the athlete to meet their carbohydrate needs, we take the higher end of the carbohydrate requirement for athletes, which is around 650 grams. By dividing that requirement by the amount provided per serving
