Glad to be of service.
My problems came after two years of antibiotics, so my ruined flora almost killed me (seriously).
Yeah, my problems worsened after multiple rounds of antiobiotics in the past and I didn't make the connection until years later. I have noticed that there anecdotally seems to be a high rate of past antibiotic treatments among people with chronic health issues, particularly those who like me notice early improvements from VLC diets, which I suspect is in part because the microbes that help with metabolizing plant foods get whacked by antibiotics. The improvements on VLC then get misinterpreted by many to thinking that VLC is best. Carb avoidance unfortunately doesn't fix the underlying problems and I have now seen countless reports from VLCers that their carb tolerance further worsens on VLC, like mine seemed to do.
However great I feel eating carnivore,
I did too early on, which I found to unfortunately be it's most pernicious aspect, as it can be quite misleading.
Do certain prebiotics cause problems for you, which are your favorite? I got a bag of the potato starch but having started yet. I am unsure if it will just feed the bad guys in my system. I know the only true way is to listen to your own body but support and advice are two things I always appreciate.
Hope to hear back from ya, Kalo
I'm not hugely fond of Bob's Red Mill potato starch, though it was the RS supplement that I first tried and got decent results from. I'm also concerned by seeing multiple people report symptoms akin to those of nightshade allergies when taking it, though some stuck it out and reported that they decreased (I'm NOT recommending that). I don't like to come across as prescribing, but since you asked, my current RS supplement faves (aside from whole foods that are rich in prebiotics, which I try to emphasize, but don't always succeed in doing so in this modern world) are tigernut flour (I have been using the Organic Gemini brand) and mung bean starch (multiple brands from Taiwan purchased at a local Thai food market--they all seem to work for me). I sift the tigernut flour through a mesh strainer, because the largest fibery bits are rather unpleasant and also as a precaution in case Ray Peat and others are right about persorption of large starch particles being dangerous. I also figure that our ancestors probably chewed and spit out the most unpleasantly gritty bits of fibery plants, though it does appear to help move the bowels, so when that's in order I'll down all of it.
The tigernut flour has been the best gentle remedy for constipation I've tried, and I've tried many,

, including ones popular at this forum like Iguana's favorite--cassia fistula (I reacted badly)--and Natural Calm magnesium powder (that plus psyllium husk powder works second best for me after tigernut flour).
The mung bean starch relaxes my muscles, gives me a sense of well being, and seems to help with my dental health, of all things (though the mineral water has been the biggest help of all on that note). I like it mixed with Gerolsteiner mineral water, as a sort of horchata.
https://en.wikipedia.org/wiki/Horchata I find it to be quite pleasant--significantly more so than the BRM potato starch.
I also now have lots of dream recall, whereas in the past there was little or none aside from a period where there were many nightmares. Non-nightmare dream recall is turning out to be an important health marker associated with such things as redox potential and memory. It's one of the things I was not warned about by proponents of LC Paleo and wish I had been. It turns out there are many things that VLC/keto proponents either don't tell you or dismiss out of hand without much investigation. Thank goodness I also checked out other sources over the years and kept my mind open. One thing I've noticed is that the more that diet proponents repeat a mantra over and over (such as LCers saying things along the lines of "eat MOAR fat!" and "all carbs are converted to sugar and sugar is poison!", and Peatarians saying "eat MOAR sugar!"--to be fair, the latter is not nearly as common, though there is some of that), the more skeptical I should be of it. If these claims really worked so well, the proponents wouldn't have to keep repeating them over and over like religious mantras. It would become self-evident.
My recent last blood test results were the best I think I've ever had (though still room for some improvement), so I seem to be headed in the right direction. As always, your mileage may vary, and I'm not prescribing for anyone else.
It was a bit surprising to learn that FODMAP foods are actually quite healthy when one has the gut microbes to help metabolize them. It tends to get ignored, but even some propopents of GAPs and autoimmune protocol diets talk about re-introducing such foods after a temporary elimination period. It pays to dig beneath the headlines into the underlying data, and I find that our ancestors tend to be better guides (they didn't eschew FODMAPs) than the latest "science" news.
