You can find many cases of complete Chron's reversal on a carnivore diet, no butchery surgery needed.
Tho some people need ~6 months for improvement to start showing.
There could be multiple reasons why carnivore might work, but other diets could also:
1) Carnivore is an extreme elimination diet, so eg gluten is fully excluded.
2) The gut temporary cannot tolerate fiber, carnivore has none.
3) Carnivore is the most low-carb diet possible, low carb diets are used all over the place (if you look outside of the archaic "modern" medicine) to treat many, many disorders.
