I was on carnivore for a while, for some weeks, a few months ago, just a little after I've started to fight high BG. I must say those were the happiest days in terms of feeling good with and enjoying meals. Back then, fasting glucose reaction got a little higher (regardless of zero or nearly zero carbs), so I felt I should back up. But most probably it was just because my body was adapting to low carb in general after years of carb abuse.
I will probably sooner of later get back to carnivore in more structured ways, so I am trying to learn more about it. I am reading now Paul Saladino's "The Carnivore Code" (just started chapter 10 today), at least to me it's been a fantastic reading.
One doubt that comes up is if people into carnivore still have to worry about macronutrients the same way other people (following other diets) do. Paul Saladino mentions that the "upper limit of protein in our diets seems to be about 40% of our total calorie intake, beyond which point we might exceed the liver's ability to process this macronutrient".
Considering that percentage, I infer one should look for fat meat. I presume the fatter the better, otherwise at the end of the day there will be more protein than necessary. Apart from what Paul Saladino says, excessive protein could also mean higher gluconeogenesis.
After months trying to stabilize BG, I've discovered that in my case
not too much protein is just as important as low carb (maybe because I am thin, BMI = 18,4). If I eat low or zero carbs, but then eat 120g of protein a day, my BG will rise. If I eat less than 20g of net carb a day and less than 95g of protein a day (1.58 gram per kilogram), then I get stable fasting BG between 83mg/dL and 87mg/dL.
So that's my doubt about carnivore. If I manage to eat really fat meat, say prime rib, I would reach my maximum daily quantity of protein with 366g of meat, but I would be lacking in a lot of calories, considering the 2000 calories a day standard. Apparently, with that amount of prime rib, I would get 973 calories, 63g of fat, 0g of carbs and 95g of protein (
source here). I'd still need more fat (to get more calories).
How could I be able to get the extra calories (1025 calories, if we adopt the 2000 calories a day standard) without raising my daily protein? Or shouldn't I worry about that and perhaps 2000 calories is not that important anymore when someone is into carnivore (best nutrients, best bioavailability etc)?
