what i mean is that if you eat 100g protein with 100g of fat or below per day, this i snot ketogenic
if you eat 100g of protein with 150- 200g of fat per day, this is ketogenic
regarding salt, im not sure... but Aajonus claimed you dont need salt if you eat raw food(animal and plant origin), but you NEED salt if you eat cooked anything
If you ate 100g of protein and 100g fat, I would say that is probably Ketogenic, at least from my experience. You have to remember that 1 gram of protein is 4 calories, and 1 gram of fat is 9. So with 100g of protein and fat, you are eating around 70% fat and 30% protein by calories. You also have to remember that on a carnivore diet you aren't likely to be consuming more than 5-10 grams of carbohydrates a day, unless you drink milk or eat honey, or are doing something else which you likely shouldn't be on a Zero Carb/Carnivore diet.
It is also, from my experience, vastly easier to eat 100-200 grams of fat than it is 100-200 grams of protein. There is no source of very high protein natural food as far as I'm aware, and there's plenty of very high fat sources such as bone marrow and the fat you can get on the muscle and organs. Bone marrow can contain anywhere from 80-90% fat or more, while most protein foods are 70-80% water, then protein and vitamins/minerals.
Regarding salt, it never worked for me on a carnivorous diet, even on a cooked one.
