For those whose energy systems are ready for it, intermittent fasting can be an effective way to regulate your body and give the gut a chance to recover. Our bodies weren't meant to be constantly full of food and the 5+ meals a day many bodybuilders follow just contributes to pancreatic dysfunction and a gut that doesn't get a chance to unload. I've tried it myself and felt better than I ever have, I just can't do it much at the moment because of my schedule.
