Phil, I wonder if you've thought about the fact that, as far as I know, none of the zero-low carbers here on this forum are reporting the disastrous effects you mention from other sources?
Which disastrous effects are you talking about? The worst effects are of course going to be the least common, and minor effects more common, as with just about any suboptimal approach. Several negative reports were pointed out to you by multiple people, and I think those people who originally reported them were mainly the ones who characterized their experience as basically disastrous (such as Brady and Lowenherz--feel free to peruse their reports, maybe I'm remembering wrongly) and others just quite bad (such as Miles, who I think only added in a small amount of carbs). You can choose to believe or not believe these people's reports and the many negative reports elsewhere from cooked VLCers/ZCers and low-starch raw fruitarians.
I agree that eating plenty of raw foods is likely a help in reducing the problems from VLC/ZC, and I think it helped me and Lex (and you) do better than most of the cooked VLCers, as I've mentioned before.
If you think something as unusual as urine therapy helps, why couldn't something much more mundane and recognized in the scientific community, like eating the better quality starchy Paleo foods, help? Your mind seems fairly made up and it seems like you're looking more for reasons to keep doing what your doing than to consider other possibilities, and I'm not out to try to change the minds of the committed, just share info with those who think there might be something better about stuff that was not well understood by me until some months ago and warn about the negative results I'm increasingly seeing reported, so suit yourself. I predict there will be an increasing sea change in the Paleo world that it sounds like you're not going to like, though it will be most pronounced in the much larger cooked sector, so maybe you'll be able to ignore it if you don't pay any attention to that sector.
It would be a bit more obvious here too if some folks who have reported privately to me came out publicly in the forum about their own experiments with RS, but I don't blame them for keeping them private, perhaps to avoid the sorts of criticisms that my posts have received. Then there's also the good results that Muhammad Sunshine reported from RS. He was the one who tipped me off about it (and like you, I was skeptical at first). So that's at least four people benefiting already in a relatively short space of time in just this little forum. Of course, I doubt you'll believe any of us, which is again your choice, and of course there will likely be some VLCers for a long time to come. There may even be ways to do it safely that incorporate prebiotics.
Another point, just read in one of your posted links where sea weed is one of the better prebiotics as well as garlic. Those are two of my daily staples I've included for many many years.
That's great, I've been eating them for quite a while myself, along with other raw veg/herbs. That didn't prevent me from benefiting from more of what was low in my diet. And who knows, maybe GCB's insect eating will work just as well for those who try it, given that they also contain (animal) starch and prebiotics like glycans. Good luck with whatever you do.
As for me, if given a choice between chufas and urine, I'd go with the chufas.
