Do what works best for you… It seems the sweet taste really helps you out! I would try to get more calories in different ways, maybe you can find something? I usually overeat but when I occasionally undereat, I usually still have better ideas than sweetened things. Those are to eat more eggs I like, I had days when I needed that… But it’s me and you do you!
But it’s quite interesting I like my desserts and they easily make me want to eat more of them but a doubled desired intake? Wow. I never had it nearly as seriously. My unsweetened desserts are better, probably due to different things, I do know non-animal carbs mess with me, especially my hunger, appetite, control. I hate all sweeteners that doesn’t contain much carbs so IDK what would happen with them.
Sweetness is fine, even lots of sugars as long as I stick to carnivore (or even if I just close) So it isn’t the sweet flavor - but if I like the food, I may eat more of it, it just doesn’t matter if it’s savory, sour or sweet. Or neutral. My carni desserts tend to be close to neutral.
Creamy and liquid stuff is different again as it’s easier and quicker to eat. If I need more calories but don’t want normal food, drinking my calories crosses my mind too. I doubt it would be good in big amounts but sometimes I just need a little extra and it can help me out there.
So it’s a complex thing.
I have no problem with sweeteners (the ones I can eat), per se but they aren’t food, you know. If they are helpful or an occasional joy, why not? But after I ate sweets nearly every time I ate for decades, I wanted to break free. It’s better that way. I still cling to my desserts but they aren’t sweets most of the time But these changes took many years. I needed a lot of sweets on keto when I was a beginner, that was that part of my journey. My SO still eats sweet desserts all the time, often cake for breakfast, it’s how he rolls and I see no problem if that suits him. I just wouldn’t want that for myself. We are different but quite health-conscious so it’s fine. He sweetens his food with either xylitol or fruit and not overly much, it seems good enough. It’s that or something worse so he did the right choice and it worked well this far. It is surely way better than the sugar we ate before.
I don’t put a huge trust in natural things compared to artificial ones (I prefer natural things, usually, it makes sense but it’s not “natural things are great and artificial ones are bad”). Sugar can be very much natural and I hate it in more than tiny amounts (or as added sugar). Stevia leaves are natural. Xylitol exists in Nature too… And neurotoxin as well but that’s easy to figure out, no need to wait for decades for the damage… But I don’t KNOW that sweeteners are surely fine and which of them, I just suppose so at this point - but skipping them would do huge harm to my SO’s diet while I eat close to zero sweetener. So we won’t change our ways for now. But we wouldn’t use sweeteners willy-nilly, that’s just wrong. It’s the same with everything, really, overeating fat is wrong and probably at least a bit harmful too… I don’t want to burden my body but I do want to easy things and making a good diet possible to begin with… I would have quit keto without sweetener, I very badly needed my sweet desserts in abundance. But I only used as little as I had to (surely sometimes a tad more but I did try and the amounts dropped more and more).
