missing a meal is just shocking the body. I would reasonably think if its once in a while it could be a good thing. possibly your body could increase metabolism and use body fat for energy, and I know damn well it wont eat away muscle or not build it. you need to starve yourself to be catabolic, but your on AAS and constantly anabolic.
when im cutting, ill do a fasting diet. its healthy and safe and eq or tren helps to not loose muscle. it works for my body but you may be different. if you look at most africans and asians, they have low bodyfat and look young as shit. its their low calorie diet and fasting if they dont have food.
