Yes, definitely. Sometimes it seems to me that people imagine the impossibility of something instead of just trying it. It’s unknown territory, we can’t possibly know how we will change and what we will desire. There are a few exceptions like I always will love fat, I consider it impossible to change, it never did and I lowered my fat intake ages ago when I went low-carb though I don’t know my old intake but it must have been super high and I still desire a lot… Just not in any ratio, I am not fit for a huge fat percentage (but would do if needed).
Some changes were very quick, basically immediately. I lost my peanut addiction RIGHT AWAY (well, if I went off, it came back, weaker but still), I lost interest in chocolate (it kind of came back? not really a desire but it sounds a good idea sometimes…? but the amount is always tiny. I still LOVE cocoa though)… Losing interest in onions took a longer time (it’s too sweet) and while I still use tomato here and there, its amount is negligible.
My desire towards fruit plummeted but no way I stop eating them, it’s a complicated multilayered thing between us and no amount of sugar and sweetness hating can’t ruin it. (I don’t hate sweetness, just the excessive amount of it. Basically all fruits are way too sweet, raw quince and lemon is still okay. Raspberries too, they are very, very sweet - they were sour and barely sweet on my original keto - but just right for a tiny amount like 10-20g. That’s a great amount for almost any fruit I want to eat. But I stop talking about fruit now… Though I could say that cooked apricot isn’t nearly sweet enough, it’s very sour. What does chemistry there I can’t imagine as it’s nothing like the super sweet, not too sour raw thing…)
I don’t know how it is with others but I lost interest in my beloved vegs (I thought I could became a vegan way easier than giving up my vegs. I was wrong, apparently) before I tried out carnivore but whenever I tried them later, they were meh and sometimes even the taste was off…? My old favs are inedible and pointless for me. There are exceptions though.
Nuts just became obsolete…? I feel them tasty but they are just not needed. I eat them occasionally though, I break walnuts all the time nowadays and it’s my fav nut but it’s for my rare off days, I can break, sort, dry and ground 1000g without eating more than 1g just fine It’s simple for me: if I don’t let plant carbs come in, temptation has little chance. If I add something, I start to change (I usually say “carbs mess with me”, it’s only for non-animal net carbs as far as I know) - but if I have good new habits and changed attitude, I still can’t be the same as I was before. I want other things now, my old carby favs don’t have power on me anymore. It’s great. Trying out carnivore was one of my best ideas ever. And it was such a crazy idea in my case…
Bread? Never was into bread, lived years without any just fine but my carnivore sponge cakes are the best bread I could have. A bit soft (or crispy if freshly made) so I can’t do everything a bread can but I don’t miss those. And I do have a low-carb bread, it’s not so great except for thoroughly crunchy sticks. I can’t do that from eggs only. Or I didn’t figure out how. But I don’t want to bother with making egg powder… Maybe adding cheese would work but only for very cheesy sticks…
So it’s possible we change MORE we can imagine. And I didn’t even do carnivore for more than 2 weeks, I have off days, I have even high-carb off days though those are super rare. I eat plenty of carby things (just rare and tiny amounts) and still, this process continues… Just like my SO felt things sweeter and sweeter after cutting out added sugar, no matter how much sugar and sweets he kept eating. I don’t even understand, the molecules are similar…
