Carnivore diet

This is my last time posting I just finished first week of strict carnivore (lions) diet. Nothing but meat salt and water with electrolytes. I took only 500ml of kefir to see how it goes, nothing much tbh. 7 days passed since i returned from hospital from severe case of UC (bleeding, more than 10 loose, bloody and mucusy stools) and my first dose of ustekinumab (Stelara). Do I feel better? I'd say I have more energy and can move more. Today was the best day and I only went 3 or 4 times to bathroom. I have developed severe diarrhea but just 6, 7 days ago my stool was rock solid. I don't really know the science behind that but it still feels hard do pass it and i never feel fully empty. My abdomen is really strange. Its really swollen and i feel pain when i push those parts. Its only around my right upper ab and it's only when I'm standing and other swollen spot is around my lowest left ab. But the main problem is in the upper abdomen. I burp all day and im trying to empty it but it never goes away. Its the worst in the morning and i dont know what to do, it causes so much discomfort. I almost dont feel any pain elsewhere (except rectum) but there is still a lot of blood and mucus. My doctor says to take ppi but it does nothing literally. When I ask her about food she just says she doesn't have any proven research that food affects UC. Only thing I talk about with her is my symptoms and medication,otherwise i wouldn't search for answers here... I don't know if I started feeling better because of new biologic or because of diet and I don't know how to fix that bloating and where it comes from. I most definitely have SIBO and I made my SIBO yoghurt but I wanted to be strict on diet. Can anyone provide me some relief, answers, anything? This is not life for me and im only 22yo... I dont even know how to listen to my own body when anything i do triggers my symptoms... I wish i wouldn't have to eat for the rest of my life
