Q. I ve heard some foods use energy and other foods provide energy.
All foods provide energy.
Protein should constitute another 25 - 30 percent. Try to include plenty of fruits, vegetables, whole grains, starches, milk and some meat. Most nutritionists recommend that athletes divide food intake into several small meals and snacks throughout the day, eating every three to four hours. Eat meals containing both protein and carbohydrates during the midday meal to avoid fatigue in the afternoon. It is best to wait to exercise at least 15 minutes after consuming a light meal or snack.
