But different kinds of foods play different roles and can help give you quick bursts or sustained periods of energy, assist your muscles in post-training recovery and spur muscular growth and strength.
    1. Increased Energy-Digestion is the process by which your body converts food into energy. Foods have different, ratings, which indicate how quickly your body uses the energy from those foods. High-GI foods are digested quickly and provide instant energy, while low-GI foods give you a steady supply of energy and keep your blood glucose levels even.
