I have made it with crispy mozzarella crust and egg/mozzarella crust. Good both ways. Just won't eat carbs. Cheat day costs 3 or 4 days. And carbs make me feel like crap. My biggest problem now is fat/protein. Hard to get enough fat without getting too much protein.
I try to eat 75% fat, 20% protein and less than 5% carbs. And only eat once per day. Never hungry
