A high fat low carb diet to start might help resolve the cravings. To go high fat, add cream, butter, cream cheese, coconut oil, that sort of thing. After the appetite is under control and the brain fog and weakness have worn off (that took me 5 weeks plus making sure I got extra salt in my diet) you can raise the carbohydrate from starchy vegetable sources and reduce the fat.
Keep your protein high. I am a short old lady and I try to get a minimum of 100g of protein a day. This keeps me from being hungry better than anything.
Another appetite bomb you may be interested in trying to kick start this thing is the "bulletproof coffee". You put your hot coffee in the blender with a spoonful of coconut oil, a chunk of unsalted butter and whirl away. Add cocoa powder for added deliciousness. This is a huge calorie bomb but if you start your day with one you may find that you need no breakfast and can go until 1pm or so before you need a meal. Eating no food at all is a form of low carb and if a buttery coffee helps you, it may be worth it in the short run.
Good luck to you.
