Intermittent fasting can have various effects on energy levels during exercise. While some individuals report improved focus and stamina during workouts, others may experience fatigue or decreased performance due to energy deficits. Fasting periods can lead to adaptations in the body’s metabolism, promoting improved fat utilization and endurance over time. However, individual responses can vary, and athletes may need to experiment with different fasting schedules to determine the optimal approach for maintaining performance without sacrificing energy during high-intensity sessions.
