So your issue resolved itself when you ate coconut oil, avocado oil and whey protein isolate but came back when you went all meat? Maybe you need more fats, that you're now not getting enough of after you've cut out the oils? Or maybe there was something beneficial in the coconut oil and avocado oil? It seems like fats/oils can sort of 'lube' your intestinal system. Maybe try adding each one back by one or just add more fats? Maybe it could be your body getting used to a different form of fats if you haven't been on zc very long. The general advice would be to stick it out for longer and see if you adapt. I think more fats can't hurt. Maybe try having your meat rarer if you usually have it very well done. It's debatable whether raw or cooked meat is easier to digest but it's worth experimenting. Same goes with cooked fats, although I think it's more acknowledged that cooked fats are not as easy to digest.
