When a significant aerobic workout is scheduled in advance, such as a marathon or aerobically challenging competition, participants can formulate a training plan that optimizes performance. Diet plays an important role in this plan, during every stage of training: before, during, and after the event. However, the body’s energy requirements also change during each stage. This chapter aims to discuss the emerging field of culinary medicine as it relates to aerobic workouts and identify ways to help patient athletes translate this evidence into practical use.
