Intermittent fasting can significantly affect exercise performance, with implications depending on fasting timing and duration. Some individuals report improved fat oxidation and energy levels during workouts due to a replenished glycogen state following fasting periods. However, it may also lead to decreased strength or endurance performance if not managed carefully. Timing meals around workouts can optimize energy availability and support muscle recovery. Ultimately, individual responses vary, and athletes should determine what fasting strategy best suits their performance needs.
