Nutritional strategies to boost energy levels before workouts involve consuming a balance of carbohydrates, proteins, and healthy fats. A meal or snack rich in easily digestible carbohydrates, such as bananas or oatmeal, can provide quick energy. Including a small amount of protein, like yogurt or a protein shake, helps in muscle preservation. It's advisable to eat 30 minutes to 2 hours before exercising, allowing your body to process nutrients efficiently. Staying hydrated is equally critical, as dehydration can impair physical performance significantly.
