It seems I function just fine with any possible amount of fiber. Zero, little, much, quite very much for a day - never noticed a difference (if the fiber significantly raises my net carb intake - it often does - that’s a different story though it’s still not a huge difference). I consider it a neutral thing for my body and I am so glad I don’t need to worry about it at all.
Can’t you just skip it or something?
If a big amount, well that’s probably not a good recipe (except my buns with half flax, half psyllium husk as dry matter was fun. I ate the whole batch, of course nothing happened, I usually love my body :D) but easy to use something else instead. I don’t think baking needs fiber, I normally use almost none (the tiny amount is from nuts for flavor) but if other fibers work, there are options. I don’t use keto baking recipes as basically all uses almond flour and I won’t pay big money for that (tried once, underwhelming) but I have zillion very different recipes, baking is easy on keto IMO - but I have spent quite much time on experimenting and it’s a hobby for me.
I go once daily on (or close to) carnivore and way more often when I eat mere low-carb… It’s surely individual but maybe people like me benefit from less fiber and you from more? But I work fine enough with any amount, personally. Most people are more sensitive, it seems.
Yeah, it may change but maybe they truly know it is for them. When I went low-carb, it was very obvious I never go back to high-carb. I don’t say the occasional day doesn’t happen but that’s it. It makes no sense to me to eat really much carbs from a hedonistic viewpoint and from a health-conscious one, it makes even less. (The best food is carnivore anyway, I just like a bit more variety and I am in love with almost all fruits and I doubt it will ever change.)
But yep, we usually don’t KNOW for sure what the future brings. I surely got some surprises after going low-carb - but I evolved into the “less plant matter” direction.
And indeed, our “ideal” diet may change. What works perfectly may be not the best later. But keto truly clicks for some people and they stay, either because it becomes normal and works well or because they have to. Of course we may need to change the style of our keto, not everyone is lucky enough to find the right one right away (who does, still may need to change it eventually but some of us aren’t a great fit with our keto in the beginning. mine had too much plant carbs and they interfered).
