I've heard that it is good to eat a banana after a workout. What does this do?

Eating a banana after exercise can help you replenish energy and restore your body’s glycogen stores. Glycogen is the form of stored carbohydrates in your muscles and liver, which are used for energy during physical activity. When you work out, your body breaks down muscle fibers to produce energy, and then rebuilds them with new glycogen. This process is called “glycogenolysis.” Eating a banana helps to quickly refill your glycogen stores so you have enough energy to continue exercising.
