I don't know much about your medical condition. I did come by the carnivore diet, which is advised to people that are very intolerant to plants. And it can also be used to then slowly introduce plants in the diet to see what works.
I also just noticed you wrote in the first post that you can't get into ketosis. That is to be expected if you are eating mostly protein with little fat and little carbs.
Protein also causes an insulin spike that prevents ketosis. So for a ketogenic diet you need high fat / moderate protein / low carb
