I don't eat meat at all, so not exactly relevant, but I found it easier to lower my carbs by increasing fats. I think they hit similar spots in my brain. And then I upped my protein in whey for survival since I don't exactly enjoy it as food lol

My point is that keto may fit your taste more if carnivore isn't. Couple that with one meal per day and you'd probably achieve your goals anyway.
