Ans. Before a workout, athletes should consume a meal or snack that provides a balance of carbohydrates and protein for sustained energy and muscle support. Examples include a banana with peanut butter, Greek yogurt with fruits, or a turkey sandwich on whole-grain bread. After a workout, athletes should focus on replenishing glycogen stores and promoting muscle recovery by consuming a combination of carbohydrates and protein, such as a protein shake with a banana or a chicken and rice bowl.
