First a little background. I am 27 years old 6'1" and weigh in at around 220. Now I am roughly about 20% body fat and carry it in my gut and lower back. Here is my dilema. I really want to cut and get around %10-%12 bf. However I am in serious need of muscle gain as well. If I go on a lean diet will my current body fat be used as energy before going into a catabolic state? Or do I need to gain the muscle I desire while on a mass diet before I consider cutting? TIA! Any help is greatly appreciated.
