Under glycolysis, you must first deplete blood-glucose and glycogen stores in order to begin utilizing fats as energy, but the breakdown of fat must then compete with the breakdown of muscle-mass. The result of this competition or duel catabolism is about as much muscle-mass lost as fat. This can of course be largely avoided thru ketosis since under ketosis body-fat is the first and primary source of energy. Ketosis is muscle-sparing for the simple reason that proteins no longer compete with fatty acids for energy utilization. Under ketosis, protein is a secondary energy source and thus muscle-mass is largely spared.
