Intermittent fasting can significantly influence exercise performance by altering the body's energy utilization. During fasting, the body shifts from using glucose to fat as a primary energy source, potentially improving fat oxidation during prolonged activities. However, performance in high-intensity workouts may suffer due to reduced glycogen availability. Additionally, fasting can impact hydration and recovery. While some may experience improved focus and energy once adapted, it’s essential to tailor fasting plans to individual workout schedules for optimal results.
