Sorry, forum, I lost every tiny self-control now that I slept too little at the wrong time. My brain functions are off and I never abandon my comments today. I don’t even know if my comments are horrible, unclear or mildly interesting. So here it is.
Congratulations! It’s wonderful to have the right woe for the current version of us 
It’s almost nostalgic to think about my old keto while doing carnivore (and ZornFast. Almost 41 hours in, I am still quite satiated. Is it determination? It actually affects my body. Is it ketosis? Is it carnivore? No idea)…
I ate sweets for every meal, basically. Not only them, I can’t start with sweets first. But as I always did, in the end of my meals. Cake, ice cream, chocolate… For one reason or another. Getting my nutrients while keeping my carbs low (my keto was a tad restricted, not just almost always completely vegetarian), making a food both my SO and me eat… And I often felt the need to fill a void. I wouldn’t call it craving, that feels different and stronger (though I never was sure my definition is craving is like other people’s). I thought it’s just old, decades long habit or really loving sweets. I am quite sure it was due still too much carbs.
On carnivore, this always present soft desire for sweets completely disappeared right away. And when I had a break when I run out of meat and ate desserts, I didn’t really like them. I still LOVE green peas and fruits. But desserts? Nope. Maybe ice cream because that’s very good and a rarity in this household lately 
I loved desserts but they are easy to get bored of. Not in general, I ate desserts very nearly every day (often multiple times) for decades. But my absolutely awesome kind of keto-friendly Sacher-cake. It was amazing but I quickly got bored. I mostly make it for my SO as he never loses interest if it’s a cake. He makes the exactly same, super boring, full-carb, 3 ingredients (including water) microwave rice cake (we call it mochi but it has raisins instead of sugar) 12-20 times a week (it’s just a guess but I must be close) since YEARS. Imagine it. Once I made a too small cake and after eating it, he immediately made a mochi too. And he has some other cake staples made by me and he eats them every week in big amounts (I mean, a whole breakfast and some leftover. 1200+ kcal). Just like he eats a pound of split peas almost every week (3-4 lunches in row). Not alone (of course, he eats it with grains. I thought it’s already side dish but nope, it’s intermediate. So there is some protein and fat too, that’s the third part) but still… He eats rice almost for every meal too since he stopped eating bread with almost absolutely everything but desserts. I couldn’t do such things.
I eat 6-11 eggs for almost every lunch but eggs are awesome and there are different egg dishes anyway.
I actually wanted to write about something else, I am just almost asleep and anyway, me.
So, our palate in the presence of lots of sweeteners and fruits every day… It’s surprising, actually. Even cutting out table sugar results in drastic changes.
I went low-carb, my SO stayed HCHF, his mother got diabetes and probably eats moderate-carb but it’s called low-carb here. We all eat close to no added sugar and love and eat sweets (I think his mother less so as she can’t make her own and the paleo chocolates she gets are very, very bad).
And we all find normal sweets horribly sweet now.
Her Christmas cake was borderline not sweet enough for me and I do the most to lower my sweetness need. They do nothing except avoiding added sugar.
I cut out carbs and did my best to use little sweetener while keeping my big amounts of sweets. Gradually, I reached unsweetened - but not black, that happened later, sometimes - coffee, unsweetened hot chocolate and finally, unsweetened chocolate (it was odd but it helped to lower my sweetness need very quickly). It’s a two-front battle, keeping some of my sweets sweet enough using as little sweetener as possible and enjoying other “sweets” unsweetened. I liked chocolate for its cocoa and fat, not its sweetness. But I can’t enjoy unsweetened cake.
Next level is ice cream but that’s easy if I “cheat” and use heavy cream. My almost carnivore ice cream was great, I used heavy cream and some rum as sweetener/flavoring. And it was just days after eating sweets and fruits and even going higher with carbs.
So pretty much adjustment is possible, it seems, no matter how surprising it is. It took years for me but I ate “lots” of fruits for years on low-carb, I had carbier days, I went on and off keto, I even ate sugary stuff now and then… When I was serious, I progressed way quicker. But the general lowered sweetness need simply happened in a few years without added sugar, for all of us. Unsweetened “sweets” are different, only I can enjoy those as I trained myself for a long time and maybe because I don’t want everything to be sweet.
I still can’t eat 90% chocolate and never will. Mine is way, way, way fattier and sugar-free.
Maintenance is the easiest thing in the world for me, usually (too bad it’s not my goal at all). Gaining is very hard and slow for me with my current weight because of genetics, my body adores this weight and I can’t eat very much carbs so my calorie intake stays normal enough and that’s what matters in my case. But I am not slim yet, it will be much more interesting later.
My SO is the one who starts gaining pretty noticeably when he stops being active. But he can’t do low-carb and it probably wouldn’t help anyway, he’s different. We never will now.
I want big meals with lots of fat too… I mean, often and while losing fat! Maybe I can have them if I eat 5 times per week? Nevermind. I am patient. Very much. Being nicely satiated is enough. Stupid old dreams… But it’s a tad stressful to minimize added fat, more and more as time passes, since several years (while stalling, of course). It’s almost completely automatic at this point and not bad but still. I LOVE fat. Just not on my belly in big amounts.
But I have a decent amount of sweet Keto treats… Cookies, cakes, fat bombs, etc… Since my GF makes / has this this kind of stuff around about 4 or 5 days a week.
lol That’s okay… I still love that ornery little chit
