I wanted to follow this carnivore diet thing, but honestly, it's wrong.
I had previously done a thing with a high fat, low carb diet, notably I was able to sit down and eat about 100g of pig fat (lard) in one meal, without any problems.
As I have mentioned previously, if you dump more than about 30g of fat, of any kind, into your stomach, it will give you diarrhea. I speculate it has to do with its saponification, and the release of laxative glycerine, which seems to cause a drastic, and probably only hours long transit through the intestines, of nearly pH neutral, unchanged oil and emulsified watery liquids.
To eat a large amount of fat in one meal, you must also consume a large amount of multiple types of fibre. My intuition about this is that the fibre slows down the action of the bile.
The other thing is cholesterol. Not the usual story cooked up by the industrial seed oil lobby to sell nickel-hydrogenated vegetable oils, which have been fully proven to be carcinogenic.
If you have too much natural cholesterols, such as found in animal fats, and many seed and nut oils, it precipitates in the gall bladder and can give you a nasty pain in the gut, upper right abdomen just below the ribcage. I had this happen to me the other day, and I concluded that it was from cholesterol in egg yolk. And similar to how ascorbic acid is laxative in excess, excess cholesterol, the natural, hard type as found in eggs, lard, etc, can form a little pebble that blocks your gall bladder, and it also, in doing this, disrupts your digestion of fats, as this is how bile accumulates prior to digesting fats, and bile's main active chemical is sodium carbonate, aka washing soda, synthesised out of salt.
So, firstly, you can have too much cholesterol, but it can give you an immediate, and painful health problem, that can lead, long term, to doctors cutting one of your organs out, for no good reason.
Secondly, you can't absorb more than about an ounce of fat in one meal, unless the fibre is present to adsorb the fats and slow down the action of bile and smooth its transit.
Third, yes, of course you can have too much fibre too. I might be wrong, but I am pretty sure it can, depending on the form, lead to constipation. Certainly, this seems to be the case for spinach.
The last thing, eggs are not good food. Probably it's ok to have a few every other day, but anything much more than about 4 a day is going to lead to biliary colic and/or other gall bladder disease.
The only diet that respects all of these facts is the Paleo diet. This diet can be augmented in a way that I refer to as the "Balkans diet", which includes fermented vegetables, notably sauerkraut, but also most of the southern european vegetables can be preserved this way, and last for all of the winter, capsicum, tomato, carrot, broccoli, cauliflower, basically any cabbage family or tomato family, or root vegetables (probably parsnips, turnips, etc) and I think stuff like artichokes can be included in this list.
These give you fibre. The diet also adds other fermented foods, notably yoghurt. The greek form, with the high fat content, must obviously not be taken alone in more than about 300ml at a time, due to the fibre problem. But if it's goat milk, the fibre problem is largely resolved as this wonder-food contains soluble fibre - and vitamin C!
Goat milk is so good that I personally want to have my own little herd to produce unpasteurised milk for me to drink. Preferably warm, straight out of the tit. Goats are also one of the easiest milk and meat producing animals you can raise, on almost any land, even the most useless slopes of mountains where cows and even sheep struggle to stay upright.
