Absolutely! When you exercise in a fasted state it dramatically increases fat burning and muscle growth, as you produce up to 300 times more growth hormone. Without the glucose and glycogen to pull energy from during your workout, your body is forced to adapt and pull its energy from fat. Since your metabolic demand during a workout is significantly higher than at rest, you will be burning more body fat during your workout. This leads to a much more efficient and effective workout giving you amazing fat burning results!
