Food choices before exercise significantly affect performance and energy levels. Consuming the right combination of carbohydrates, proteins, and fats can enhance endurance and prevent fatigue. Complex carbohydrates, such as whole grains, provide sustained energy, while simple sugars can offer quick boosts when needed. It's also essential to consider meal timing; eating too close to a workout can cause discomfort, while an ideal pre-exercise meal consumed 30 minutes to 2 hours prior can optimize performance. Staying hydrated is equally vital, as dehydration negatively impacts physical capabilities.
