Answer

Casper needs a diet containing an increased amount of carbohydrate for several reasons. Firstly, he requires more energy for his training and races. Carbohydrates are crucial because they contain and release energy when metabolized. During this process, carbohydrates are broken down into glucose, which is a vital energy source for his muscles. This breakdown occurs by enzymes or amylase during respiration, ensuring that Casper has enough energy to perform at his best.
