Fasting before a workout can affect performance depending on the individual's fitness level and workout intensity. For some, fasting can improve fat oxidation, potentially enhancing endurance during long sessions. However, others may experience decreased energy, muscle strength, and focus, especially in high-intensity or strength-training workouts. It's essential to find an optimal eating schedule that aligns with personal goals and energy needs. Pre-workout nutrition can help fuel performance and recovery. Ultimately, tuning into how the body responds to fasting is vital for optimal performance.
