An athlete's diet should be different from the normal diet of the individual. Athletes, in addition to the needs of everyday life, need fuel to practice and compete, food supplies fuel for athletes, but most athletes are unaware of the fuel they pour into their tanks. Protein, fat and carbohydrates are your body's energy. All foods do not have the same content content. Just like racing cars need high octane gasoline. Athletes also need high-grade carbs.
