Some athletes like poached eggs, toast, and juice as a light pregame meal. Some prefer breakfast cereal with low-fat milk, toast with just a little jelly, and juice.

The aim of this practice is to increase the amount of glycogen , or animal starch, stored in liver and muscle tissues. The body makes glycogen from extra carbohydrates it has. This stored glycogen can be broken down and used for energy when needed. That's why it's good for athletes to have sufficient glycogen stores in their bodies at the start of an event. While on this diet, the athlete exercises strenuously.
