Foods can significantly impact energy levels during exercise, with carbohydrates being the primary energy source. Simple carbohydrates provide quick energy, ideal for high-intensity workouts, whereas complex carbohydrates sustain energy during longer, endurance activities. Conversely, fatty and high-fiber foods can cause gastrointestinal discomfort and hinder performance. Consuming a balanced mix of carbohydrates, proteins, and fats before workouts can enhance endurance, minimize fatigue, and improve overall exercise results, making strategic food choices essential for athletes.
