The significance of meal timing in relation to exercise lies in optimizing energy levels and enhancing performance. Consuming meals at strategic times can ensure adequate fuel before workouts and support recovery afterward. Pre-exercise meals should focus on easily digestible carbohydrates and moderate protein to provide energy, while post-exercise meals should emphasize replenishing glycogen stores with carbohydrates and aiding muscle repair with protein. Timing meals appropriately can minimize fatigue and enhance endurance during workouts, leading to better exercise outcomes and overall health.
