That's just not how the body works. If you're losing muscle you're losing fat as well. Generally you don't get into muscle loss until you're at a very low body fat percent (anorexics) or if you're eating an absurdly low number of calories and are sedentary. The body WANTS to use the fat first and preserve the muscle, muscle is a last resort. So no, that's not realistically possible within the bounds of thermodynamics.
