i tried it a while back, but with my kidney problems and issues with a half busted wisdom tooth, the chewing is quite difficult. but it certainly was not causing any further decline in the state of my kidneys. however, the thing is that too much protein can be a bad thing for someone in my condition.
as such, i am more or less paleo now, but mostly i eat milk and cheeses, with a small amount of veg, i'm quite fond of balkans style fermented, and obviously i have to keep my sugar intake down, and completely avoid fructose if i can. so, a bit of low fructose fruit, cherries, peaches, plums, and citrus, one or two pieces a day.
of course there is no influencoors selling the idea of a milk-based diet, but now you have heard of someone doing it. i do also eat a bit of eggs, but the eggs i was getting on madeira were contaminated with something from the feed, probably monsatan corn.
which also leads me to comment on meat - it's not so much of an issue in usa, canada, uk, australia, new zealand, but in europe, actual beef is almost impossible to find except at specialty butchers, everywhere else it's feedlot, corn-fed veal, sometimes you can find lamb, but forget about mutton, all the chicken and turkey is also pretty much corn fed trash, and especially if you buy chicken livers or similar, the smell of the corn on the meat is sickening.
don't even bother to try carnivore if that is the state of your meat supply.
but if you can find it, switch to beef tallow for frying, this is one of the most important parts of what makes carnivore good as an elimination diet, and it tastes damn good. here in balkans mostly impossible to find but even tiny mini markets usually sell 'svinska mast' aka lard. also, probably best to avoid most kinds of sausages, though the worst of them is they contain potato, but more concerning is the chemicals they put in them, unless you can find nitrite free, this is also quite crappy.
not exactly a straight answer but it should give you a guide to how difficult it will be to find decent meat where you are
