It was some extreme, hardcore group to me that I never will get close 
It seems supplement wise too, people are simply different. Do what works for you.
I canāt really take supplements, itās against my core personality or something. I had cramps on keto (always due to too little magnesium, at least a magnesium pill always solved it) and that was motivation to supplement magnesium so I had 1-2 250mg pill a month. I just canāt supplement more unless I am in pain without but I never was.
But if I eat enough meat and little enough carbs (being quite close to carnivore), I donāt need magnesium. I always needed it here and there on keto (my old keto, I mean, it was a carbier vegetarian keto). If I went into ketosis without, I got calf cramps.
I will look up how much magnesium I eat on carnivore but itās probably still lowish compared to the usual advice/requirements but as I eat differently, who knows how my needs change? We know that our Vitamin C need drastically lowers on carnivore, maybe it happens with other nutrients as well. Probably do.
I never supplement sodium (not even when I fast but I canāt seem to do EF on carnivore yet) but thatās me. The more carnivore(-ish) days I have, the less saltiness I like in my food but itās merely significant,. not very drastic, I still like my salt, I just need somewhat less. But I am just an on/off carnivore-ish since almost 2 years, I surely will change in the future - and do whatever my body wants me to do salt wise.
Other find they need much salt and thatās just as fine. Each to their own.
Why I tried to do carnivore despite it felt Very Surreal for many months? And I have no problem with plants at all (just with their carb content. except peanuts, my body doesnāt like them in more than minimal amounts. too bad I was super addicted to them on keto), donāt believe they are usually bad for me, I donāt even think I need healing though surely my health can be improved so yep, maybe a tadā¦ But I felt healthy enough on HCHF as well let alone low-carb. Keto didnāt give me much benefits, only fat adaptation but my body liked eating less and less carbsā¦
Nope, my main reason is that carbs mess with me, mostly mentally, well mentally/physically? I always had a hard time to get satiated. I always did it, no way I stay hungry (except on my yearly maybe one Insaniable Hunger Dayā¦ I never had that on carnivore, not even on carnivore-ish but I didnāt have soooo many carnivore-ish days yet. many but not nearly as many as carbier ones and itās a rare thing) but it took very very much food. I overate almost all my life as I was hungry and undisciplined and compelled to eat. Itās multilayered. I had some food addictions too.
And carnivore just solved these problems right away. My food addictions disappeared, my decades long āsweets on the end of mealā went away (keto didnāt help as I actually needed lots of sweets there to get my nutrients while keeping my carbs low enough), it did very good to (against) my stupid compulsionsā¦ I canāt just eat meat until I get satiated so some hardships were present here and there but usually itās so chill and enjoyable and all is good! I still go astray due to reasons but as time passes,
I get better and anyway, my off days are nothing like in the past. My egg and meat is my normal food. I may add extras sometimes but I donāt go and try to get satiated with something carby, it would be stupid, unpleasant and ineffective. I strongly prefer my normal food, that gives me most joy and least problems.
But I do it for weight-loss too. I consider it my only real chance, at least if I can stick to OMAD on most days (2 meals are way too much food for me, usually. not always and I do need my TMAD days as I canāt eat big enough meals every day on OMAD). Nothing this far but itās a good method, I just need to stick to it 
Whenever I manage to do it stricter and/or longer, it seems to do good. And I get stronger so I donāt care about fat-loss even as little as before right now, I want bigger muscles
Oh and I want more energy. I suspect I will get it if I stick to carnivore(-ish). I seem to be a less miserable zombie on carnivore in the morning. I never have much energy, itās individual and I donāt get that luck but every little improvement is good. I typically had low-ish energy on my original keto.
I would do almost anything for much energy. I would eat ONLY meat for it and I really would like to avoid that fate, I love my eggs. But much energy must be awesome to have.
Well-being is important too and the less carbs I eat, the better I feelā¦ But if it would be just some peace instead of more hunger and sometimes compulsive eating, I already would be hooked. Give me more than minimal carbs and I can eat huge amounts (and āI canā means here that itās very easy and under some too common circumstances I feel compelled to do so)ā¦ And 1-3 hours later I can repeat it. High protein and high fat canāt help with that, carbs must be very, very low. So I have some weird sensitivity to carbsā¦? OMAD kind of solves this problem but itās still far from ideal. And carby OMAD would be good only for maintenance anyway but only if my body would like carbs. It doesnāt.
Elimination is very useful. I have my stricter times. I often try no dairy for a while. I ended up with no cheese almost all the time, now I eliminate cream but a few items have their uses. But I still have no dairy times too (except maybe a little butter here and there), I plan such a week on November (or more time, I donāt know, I do until itās comfortable. I donāt push it as I donāt seem to have problems with dairy, itās just often unnecessarily and in the case of some items, it triggers something not so good like eating too much fatā¦ I too easily eat a ton of fat - carnivore helps a lot though -, no need to use non-satiating fatty dairy!). Some people actually need a no dairy policy, I am fine with this food group but it boosts my calories and I donāt need that (maybe quark being the exception, itās protein rich and not very fatty, it probably satiates me but as I always use a little, I canāt tell). They donāt feel proper food anyway. I mean, not good for staples. A little for variety if one can handle them is fine. I had times when I just couldnāt eat enough using ONLY eggs and meat, I needed my dairy then (even if it always was a little amount, it helped me eating more eggs than without).
Oh yep, this is my desire too. Except my coffee isnāt decaf but only because normal coffee is cheaper and I found a nice non-bitter one, I really donāt care. Of course, itās naivety to underestimate my coffee addiction (my only food/drink addiction that did nothing on carnivore)! I drink coffee with eggs and butter now, sometimes black. But I donāt like it black and my fasting window is long so I really hope my 10+ coffees a day times wonāt come backā¦ (Weak coffees but still. Stupid thing.)
