I'm not a "carnivore influencer" despite my name but am an actual long term carnivore, in reality.
Carnivore v keto are just terms which designate food ingredients, if you will.
Carnivore is necessarily ketogenic in its mechanism in our physiology, but the terminology is a little confusing. You can be ketogenic in a variety of ways which are less than effective, or even quite bad for you, but not necessarily carnivorous in your respective diet.
Traditional or varietized ketogenic diets bring in a "low carb high fat" dietary framework which often includes a lot of ingredients coming from plants in forms otherwise somewhat inaccessible in a less than industrialized/civilized modern world. Using abundant plant oils such as ones from coconuts & olives along w/ a fair amount of fiber in the form of all the *acceptable carbs* which create the basis of less than carnivorous ketogenic diets are the problem. The macronutrient ratios may indeed be about as ketogenic as a diet of nothing but ribeyes & eggs which is indeed "low carb high fat", except not including any plants, necessarily, unless you consider that the animal's diet was mainly plants which were upcycled into animal protein i.e. all carnivores are vegan but the animal acts a gateway to otherwise inedible to us plant matter as we have a different digestive mechanism which cannot effectively extract the nutrition from those plants like an animal's can. That's why they exist as transformative food for us. Without them, we would sure die bc, dietarily speaking, we'd be in a type of "survival mode" eating nothing but their food aka veganism which bypasses the animal.
In a response within this post, Roosh himself mentions that it was a gastric condition. Well, whether he'd admit it or not, he's tacitly validating the subtext of a carnivore diet.
The reason many think that some ppl are better on carbs vs something carnivorous is contained in what a carb eaters distorted physiology would convince him to believe about himself. In short, "meat aversion" is a circular cause and effect of "meat aversion".
To disprove the false premise that humans are not entirely carnivorous, just go hungry for as long as you can and try to simulate existing in nature where you don't know what plants are edible vs deadly, yet, there's abundant animal life present around you.
You'd kill and eat the animal and you meat aversion/state of impending doom would be fixed immediately.
Of course, this isn't the reality we really exist in so, yeah sure, let's just argue about dietary terms which are still only designating food ingredients.
You can only eat from the animal or plan kingdoms of sentience. Humans live on the ground, not in it, yet, are indeed the Apex of the animalic realm of sentience. We are at the top of the great [food chain] of being and are intended to eat mainly w/ in the realm we exist in. Right below us is the broader animalic realm which is intended to eat from the plant realm right below it. Following that downward chain of being, plants eat from the mineralic realm and combine w/ sunlight energy to cultivate the very basis of ALL nutrition necessary to fuel life, itself.
Bet your average carnivore influencer has no idea what I'm talking about because even they are caught up in modern terms creating the dialectical "ideological diet wars"
