I’m trying to follow the PKD (thank you, FrankoBear) but I’m only about 1.5 months in. I was regular keto for 3 years before that. Regular (strict) keto was helpful and I saw some improvements with my health but I’m trying the carnivore/PKD to see more. I wrestle with many auto-immune issues and I’m older so it may take me longer to see any big results. I believe the folks in Hungary have said, for instance, that crohns can take at least 6 months to see big improvements.
So far, I’m really enjoying carnivore itself. My only problem is that when I eat 2 to 1 fat/protein I put on inches around my waist although the same thing always happened when I tried to do the same ratio on regular keto.
As far as trying to get enough fat for the 2 to 1 ratio, I like a variety of fat options. Sometimes I’ll eat raw suet (genuine suet) and other times I’ll use rendered tallow, pork or some other animal fat. My favorite way is to buy extra fat trimmings and bake them in the oven low & slow, yum. Also, don’t forget the organ meats!
Like I said, I’m new to carnivore/PKD but eating meat now seems totally natural to me somehow like I’ve been doing it (or should’ve been doing it) for years. This is super surprising for me since I wasn’t really a meat eater before this.
I hope you see great results on the PKD. I’d LOVE to see them open a clinic over here. We’ve got carnivore docs here who could be a part of that. 
Edited to add: @FGH Frank, remember too, that some folks doing the PKD are put on nothing but some kind of creamed meat mixture for 30 days! If, like me, you are tackling some big health issues, be sure to arm yourself with patience.
