Frankly that makes no sense in the context of a bodybuilder. All of those studies listed in the review you posted are targeting either overweight people or "normal weight", both miles away from the body composition of a bodybuilder. You can't take that and try to apply the same results to someone who's got their diet, exercise, sleep, daily steps, even salt intake dialed in like a bodybuilder does. We all accept there will be muscle loss when you diet down. Heck, most natural bodybuilders probably have to drop 10kg before they are ready to go on stage.
