I appreciate the thought put into this 'thesis'. May I suggest that you post this to Ron Rosedale, he has a blog, and see if he'd care to respond to your conclusions. I for one would love to see his response. I think it would add value as I'm sure, if he did respond, he would include some science to ponder over.
One of the difficulties of using say the Inuit as a barometer is that they didn't eat for longevity, except you might call it longevity of the moment, or simply to survive the day. Another way to say this is, I wouldn't use a wine drinking alcoholic to study the health benefits of wine.
There may never have been any group of peoples who knew how to use diet to maximize longevity. For sure we know of no strictly raw eating peoples.. That is why I say one has to dig deeper, or be willing to experiment with one's self. But please, blog Ron, see if he'll respond. thanks
This post is wholly inappropriate for the ZC forum. I will put it in the hot topics forum instead.
Is there no place for intellectual criticism on these forums?
Is there no place for intellectual criticism on these forums?
Yes, there is room for criticism, this thread was not deleted not censored, this is why this raw paleo diet forum exists and Tyler and the other mods try to keep a balance.
There are those who really follow the zero carb thing and it works for them and just to respect what is working for them, criticisms are placed in the hot topics section.
I am not a zero carber, but I respect this zero carb section.
I whole heartedly agree with many points of the very very nicely written piece. Thank you.
And I would have to agree with Tyler it still belongs to the hot topics section.
aem42290,
I am wondering if you gained benefits initially from VLC that were worthwhile, and if you had started to very slowly increase carbs early on that might have worked well?
I have been interested in reading the research of Paul and Shou-Ching Jaminet (The Perfect Health Diet book). In regards to carbs their findings are that the ideal is 30% of energy from carbs (Typically ~600 calories), from 'safe starches' like potatoes, rice and bananas, to provide for the bodies glucose needs, and the rest from fat.
Here is Paul's investigation of ideal glucose levels for longevity and dialog with Ron Rosedale:
http://perfecthealthdiet.com/2011/11/safe-starches-symposium-dr-ron-rosedale/ (http://perfecthealthdiet.com/2011/11/safe-starches-symposium-dr-ron-rosedale/)
Hey, Van. Thanks for your response and for your (earlier) reply to my PM. Really appreciate it.I don't know,, I have never entered a post there. Why not just give it a try in whatever way you think might get to him. And for the record, I wouldn't move this to hot topics. You've entered something quite valuable for all of us to ponder. The zero carb diet is a man made phenomena. I do well on a diet very very low in carbs, but better with the inclusion of foods that apparently add fiber, minerals, and prebiotics to my gut. I'm a big fan of seaweeds, garlic, leeks, radishes, pumpkin seeds, lemons (very ripe meyers for bit C) kale when it's not unappetizingly bitter, and wild greens. I will also eat in the summer a few figs, cherries, apples.... but with those, I can feel that they really detract from my energy or feeling stable throughout the day. I added this last part here to remind some here that one can still go close to zero carb and still feed one's intestines bacteria producing food, and include outside sources of trace minerals. All of which a hunter gather most likely would have included with his primary meat and fat meals.
I agree, we do need to continue experimenting. I wrote this thesis to dispel the notion that ZC diets are optimal/healthy long term. I feel strongly about this, considering that the diet eventually took a silent and fairly insidious toll on my body. Hence why I thought it'd be meaningful to share my knowledge with this excellent community.
How would I go about posting this to his blog? Should I leave it as a comment to any specific threads?
Tyler,We have to be fair to all. Most followers of specific diets like RZC would far prefer to read positive threads on how to pursue an RZC diet or whatever than to read posts on how supposedly "dangerous" that diet is, especially when their own long-term experience re RZC is very positive. There is nothing wrong with posting controversial topics in the Hot Topics forum, where this thread is now, as that is a suitable place for that sort of thing. I have therefore not censored anything, just moved it to the right place.
With all due respect, I believe that putting this post in the "hot topics" section is unjust. Inappropriate in what sense? What I have written is a reflexively critical piece that deals with ZC diets directly. Is there no place for intellectual criticism on these forums? I do believe that those on a ZC diet have the right to be exposed to what is on the other side of the fence. Moving this post to "hot topics" seems almost punitive.
It seems that quite often there are people saying that eating zero carbs initially provided benefits, but over time 'ruined' their health.
If the moderators keep moving the evidence of these issues to a place where they won't be noticed then how are newbies looking at ZC to know ?
If keeping the critical posts in the topic cannot be tolerated, then how about a sticky post providing some warning of this, plus a reminder that there is a lot of room to be low carb without being zero carb.
Looking at the description for this topic it says "Not literally zero carb but eating only from the animal kingdom: muscle meats, organs, and fat of sea, sky, and land animals alike -- the raw meat diet for humans."
Eveheart is the moderator and she says that she eats low carb plant food, as does Van.
Inger likes to post here, but for her it is more about eating with the seasons and nature, and being low carb temporarily.
So this is a carnivorous / zero carb diet title seems misleading, as it is rather a low or very low carb diet.
So this is a carnivorous / zero carb diet title seems misleading, as it is rather a low or very low carb diet.
I would like to echo sentiments expressed by Van, Alive, and Eric in pleading for the moderators to either move this post back to the ZC section, or add in a warning sticky to the ZC section directly that addresses nuanced critiques of the diet. Critical resources are necessary for people starting a ZC diet. I would have benefited greatly from reading critical topics when I first learned of ZC from these forums. I certainly didn't think to look in "Hot topics."Yup. I wish I had seen more warnings about the risks of chronic ZC/VLC. When I experimented with it, I thought it was a relatively harmless thing to try for a month or more. I hadn't heard of the Old Friends Hypothesis at the time. To hide away the negative reports and information by moving it into other vague subforums gives a misleadingly positive picture. More people may suffer unnecessarily as a result. It's also rather telling about ZC, indicating that it is so weak an approach that it cannot stand up to direct critical scrutiny.
I do great with ZC in summer too, but I am crazy about everything wild!!! I love wild herbs, berries, mushrooms and flowers... but those have almost no carbs where I live.This is one thing that's so confusing about supposed "ZC". I've seen it defined so many different ways. Since when are berries and mushrooms and "seasonal eating" included in it? Berries contain significant carbs. Here's just one example of raspberries (15g of carbs in 1 cup--82% of the calories as carbs): http://nutritiondata.self.com/facts/fruits-and-fruit-juices/2053/2 (http://nutritiondata.self.com/facts/fruits-and-fruit-juices/2053/2)
I really believe in seasonal eating. When you do not get plenty of sunlight, carbs are going to hurt you in the long run.
And for people in high man made EMF areas around the globe, ketogenic year round....
The forum title "Carnivorous / Zero Carb Approach: Not literally zero carbIf it's "Not literally zero carb," then why call it zero carb? For most people in the world, zero still means zero. Why not just call it "Carnivorous"?
If it's "Not literally zero carb," then why call it zero carb? For most people in the world, zero still means zero. Why not just call it "Carnivorous"?
Chronic truly zero carb (as in zero or as close to zero as possible) really is a myth-based approach that has no precedent in all of human history and is thus a novel experiment which makes guinea pigs of human beings. No one can say for sure that they know that chronic ZC is safe for anyone in the long run because it's never been tried before by any human society. To pretend otherwise is unconscionable.
Where are people still getting the idea to do "ZC"?
Now granted this maybe totally because I eat seaweed on a regular basis and garlic and a few other prebiotics and have been for many many years,, even when I was on a high fruit diet.Thanks for sharing this. I do indeed suspect that the carby foods that you, Inger and Lex eat (Lex's pet food mix that contains carb-containing raw organs is another example) may help explain why you folks seem to have fared better than most people who have tried diets that were closer to truly "ZC." Even with your diets, there may be risks. Lex's results have been less than 100% positive, for example, and no one knows what will happen in the longer term, as there is no historical precedent for even Lex's approach that contains some carbs. The evidence I pointed to before indicates that even the Eskimos ate more carbs than had previously been assumed.
Phil I think you're missing the point here. I don't think most of the members here care about Charles or the Bear, or even Lex for that matter as some kind of guru.I didn't say they did. I asked where people are getting the notion from to do ZC, and I'm particularly interested in hearing from the newer folks who haven't already shared why they're doing it/tried it. If it wasn't from Lex or Charles or the Bear, then where did they get it from, especially given all the information that's been coming out that contradicts the notion of ZC? It seems like there's more scientific evidence contradicting ZC and more reports from ex-ZCers and ex-VLCers who reported improving when they added carbs or prebiotics coming out on the Internet nearly every day now. I've only shared a fraction of it and I wouldn't have time to gather, compile and share it all. Of course, most of it involves people cooking most of their animal foods, which is the worst sort of ZC that I doubt you'd be much interested in anyway.
Now granted this maybe totally because I eat seaweed on a regular basis and garlic and a few other prebiotics and have been for many many years,, even when I was on a high fruit diet.There's another example. Seaweed is forbidden on ZC, as kelp is reported as 79% of calories as carbs: http://nutritiondata.self.com/facts/vegetables-and-vegetable-products/2617/2 (http://nutritiondata.self.com/facts/vegetables-and-vegetable-products/2617/2) So why defend ZC at all or take umbrage when people write less than thrilling results from it or critiques about it, given that you yourself are eating carby food? It's strange to see people who would be ridiculed on the ZIOH forum defending ZC or taking issue with critical posts about it.
And I don't 'insist' upon my body to be able to 'handle' honey or fruit or any other form of sugar, nor am I interested in how to convert my body somehow to be able to eat sugar.Where did anyone 'insist' that you do anything or talk about insisting that your body do something it's not ready for?
So, can we agree to give up the hype about ZC and simply call it low, or low low carbOf course, that's what I've been asking for quite a long time, and I suggested that the "ZC" be taken out of the forum title, which was dismissed without a good explanation for the contradiction in the subtitle.
and not worry about what Charles does or doesn't do?Huh? I said his forum is moribund. What are you talking about? All I asked is where people are getting this strange idea to do ZC. I thought Francois' question about where people are getting the notion to try a frankly bizarre and extreme dietary approach was a good one. And I'm also curious as to why some folks keep writing about doing ZC, or taking umbrage with critical posts about it, and then say that they're eating foods that contain carbs, like berries, seaweed, etc.? It's rather confusing, and it's strange to see some people still writing positively about it and some still claiming to follow this risky approach that hasn't been tested over the long run by any human society when it seems to be dying a well deserved death, though there will likely be stubborn holdouts for a long time to come, just as there are with the most extreme vegan diets.
Call it Low-Carb ApproachThat sounds like another good idea, and since the subtitle says it's not literally ZC, I don't see why anyone would have a problem with removing the "ZC" contradiction from the title. Either low carb or carnivorous seems fine to me. It doesn't seem like that big of a deal to make that small change and it's strange how negative the response was about it in the past.
There is already an Omnivorous Raw Paleo Diet: Animal products with some veggies, berries, and non-domesticated, wild fruits added to the mix. The topics on that thread do not reflect the idea of "some veggies, berries, and non-domesticated, wild fruits added to the mix."Yeah, and it's strange to see those foods discussed in diets that are referred to as "ZC" or in the context of ZC.
"Some veggies, berries, and non-domesticated, wild fruits added to the mix" sounds more like a Low-Carb Approach, but honestly, only some of us can source "non-domesticated" wild fruits."Yeah, that's another oddity in the titles that I noticed before. It makes it sound like there's no room for higher carb approaches in even the omnivorous section. However, given the uproar that suggesting a more consistent Carnivorous section title caused, I figured it was hopeless to request that title be also improved into one that makes more sense.
It seems that quite often there are people saying that eating zero carbs initially provided benefits, but over time 'ruined' their health.Indeed, and based on aem42290's feedback, it seems like more warnings about ZC are needed, rather than less:
If the moderators keep moving the evidence of these issues to a place where they won't be noticed then how are newbies looking at ZC to know ?
I would have benefited greatly from reading critical topics when I first learned of ZC from these forums. I certainly didn't think to look in "Hot topics."
From the standpoint of most of the moderators, the answer to this question is unfortunately "NO". It doesn't surprise me at all that this thread was banished to the 'Hot Topics' section, although I personally think it was fine in the ZC section.Hi guys,
Above, PaleoPhil mentioned twice that a fundamental question I asked was never answered. That’s it, and this one is far from being the only fundamental question I asked which was never answered.And it still remains unanswered, as do my other [above] questions.
It seems that quite often there are people saying that eating zero carbs initially provided benefits, but over time 'ruined' their health.Some people have failed on RZC just as others have succeeded on RZC. Putting the more hostile posts in the hot topics forum prevents people from becoming unnecessarily scared when they first try this type of diet out. No need to put a warning message - after all, we don't put out warning messages for the primal diet forum either. Low carb really belongs in the raw omnivore diet forum, imo.
If the moderators keep moving the evidence of these issues to a place where they won't be noticed then how are newbies looking at ZC to know ?
If keeping the critical posts in the topic cannot be tolerated, then how about a sticky post providing some warning of this, plus a reminder that there is a lot of room to be low carb without being zero carb.
Yes, it's quite strange that Paul Jaminet advocates 25% carbs and is pilloried by LC zealots, whereas Dr. Rosedale is a LC hero for advocating 20%. Go figure. What does this tell us about the level of dogma and guru-worship in dietary circles?If you're asking me, I don't remember, it was probably 8-9 years ago. And, again, I'm not interested in all the gurus, but what works, and any science that backs it up. I don't know anyone in this forum that is promoting an actual ZC diet, so I'm still puzzled why you're so fastidious with proclamations about the danger of ZC. And again, there are several regular posters here that seemingly do just fine if not excel with going low carb. So why all the fuss? And again, can we please simply describe what foods work well for any of us while maintaining a low carb diet. That is what most likely will help the most with those interested in it, vs. all the repetitious fear posts.
I have indeed seen lots of media stuff, but it hasn't been zero carb, just low carb or ketogenic. Outside of this forum and some ZC/LC forums, ZC is still largely regarded as insane. Dr. Kurt Harris called ZCers “the Hezbollah of low-carb," even when he was VLC and a Jimmy-Moore touted "low carb doctor" himself. It's ironic that only after the problems with excessively chronic ketogenic diets are becoming increasingly apparent that some of the media and various doctors and gurus like Perlmutter, Oz and Weil are now trying to cash in and jumping on the LC/keto/butter-loving bandwagon, not realizing that its wheels are starting to come off. ;D l)
Iguana is apparently in tune with this reality that ZC is regarded as insane outside the boundaries of this little forum, which would explain why he's so puzzled by the positive and defensive comments about ZC and near-ZC that still appear in the forum at times.
So, again, how did you first hear about ZC?
I remember the time when there were so many attacks against Instincto and they also wanted a pin on the Instincto section.Yes, I remember. Same things were said about the Primal Diet and the Wai Diet forums at other times. But because we did not allow any of those forums to be banned or whatever, we have managed to offer people a wider range of rawpaleodiets to choose from.
I'm sorry, but I don't buy any of this thesis. Writing a post that is 10 miles long does not add to its validity.
There is no account for the glycerol that is released on fat breakdown being easily converted to glucose.
There is no account for glycogen consumed in muscle and organ meats converting easily to glucose. There is no account for glucose being consumed directly in fresh blood.
There is no account for glucose being consumed directly in fresh blood.
At best, gluconeogenesis is a temporary condition that is used to provide up to 100g of glucose per day until one is fully adapted to ketosis.
The short life span in carnivores is explained by the fact that their food and their competition is trying to kill them almost every time they eat. Eventually they get old and get gouged in a hunt or a fight and succumb to an infection or bleed-out. There is no need to complicate it any further than that.
Thank you for this response. I do appreciate that you have done some research regarding this. If my earlier post seemed a bit agressive, it was. Just as your post was very condescending towards the zc camp. I just felt that several important concepts were overlooked to make an argument seem more plausible and that you were making the offense of assuming causality when there is only correlation with things such as lifespan and other points. I suppose the purpose of a thesis is to make an assumption, but there are just so many here. The concept of preferring pathways for their lack of energy requirement alone is not relevant in today's society with plentiful food available. I would be more concerned with whether they are doing damage along the way or not.
Yes I am aware of muscle glycogen converting with rigormortis, I mentioned it as it applies to eating freshly killed meat and the contribution is small when compared to eating liver, the glycogen of which remains in tact.
I'd like to continue this debate if you would indulge me, though in a more gentlemanly manner. I must say its been a while since I have researched any of this and its possible that there is new knowledge out there. This is one of those things where you can't just take any study and run with it because there are vested interests that like to fudge numbers and mislead people when health is at stake.
I believe that there is no such thing as a zero carb diet. Even predatory animals eat some carbs from organ meats.Bingo! Excellent post, Sabertooth. And when meats are fresh and eaten raw, or raw fermented, or fresh-frozen, one can get some carbs from the meat, blood, connective tissues (skin, ligaments and tendons) and even blubber as well:
"Eskimos actually consume more carbohydrates than most nutritionists have assumed. Because Eskimos frequently eat their meat raw and frozen, they take in more glycogen than a person purchasing meat with a lower glycogen content in a grocery store. The Eskimo practice of preserving a whole seal or bird carcass under an intact whole skin with a thick layer of blubber also permits some proteins to ferment into carbohydrates."See also:

Aem- I think that in order to fully gain a wider perspective on the evolutionary history behind the ketogenic diet you must go back much further into our evolutionary past. Before we had evolved into herbivorous apes, our proto primate ancestors once lived as carnivorous insectivorian tree weasels.In addition to insects, the shrew-like and lemur-like ancestors of the first primitive primates (called Plesiadapiforms), are believed to have also consumed fruits and fermented tree nectars and saps:
how did you first hear about ZC?OK, so we have an unknown source along with Bear Stanley and Charles Washington as the sources of the ZC notions. Stanley and Washington were influenced by Vilhjalmur Stefansson. Stefansson didn't tell people to eat truly ZC (it would have greatly hindered the popularity of his diet, for one thing), but he is the most cited source of evidence by them. Does anyone know of any other sources? I'd be especially interested in any scientific ones.If you're asking me, I don't remember, it was probably 8-9 years ago.
And, again, I'm not interested in all the gurus, but what works, and any science that backs it up.I'm interested in the science too, so if you have any science re: ZC, please do share it. I hope you'll appreciate that I shared some science articles above.
I don't know anyone in this forum that is promoting an actual ZC diet,It did seem like it had come to that until edmon171 spoke up. I welcome his input.
so I'm still puzzled why you're so fastidious with proclamations about the danger of ZC.My posts were aimed not to anyone who doesn't think warnings are necessary or are not interested in the topic, but to folks like aem42290 and anyone else who is. Edmon171 also doesn't seem to mind the discussion. It wouldn't be much of a discussion if we were only allowed to hear from defenders of ZC, would it?
And again, there are several regular posters here that seemingly do just fine if not excel with going low carb.Are you aware that my diet is LC? If not, it might help explain why you interpreted some of my posts in ways that were not intended.
And again, can we please simply describe what foods work well for any of us while maintaining a low carb diet. That is what most likely will help the most with those interested in it, vs. all the repetitious fear posts.If that's what you wish to discuss, why not make a thread with that topic? I think there's room for both discussions and don't believe in silencing dissent from folks like aem42290, and I like what Iguana, Eric, Alive and Sabertooth contributed to the discussion and don't consider it all "repetitious fear posts". I also welcome the perspective of you, edmon171, Inger and others.
The fact is that there are plenty of people doing RZC, some of them not eating any raw plant foods at all.We have heard from one. Like GS, I'm glad he spoke up and I'd be interested in hearing from others.
In fact, in the past, we were so dominated by pro-RZC advocates that I felt I had to stop them from overwhelming less popular dietary genres like raw omnivore by my refusing to allow the raw omnivore forum from being removed as it was claimed, at the time, to be "pointless since hardly anyone is raw omnivore any more".Interesting. Thanks for your efforts.
Point is we cannot exclude one dietary path simply because a tiny handful of people here do not want it around.I'm certainly not calling for the "banning" of the Carnivore subforum and don't want it to be banned. Like GS, I want to share and learn. I do agree with aem42290, Eric, Alive and Iguana that all civil perspectives should be allowed in all subforums, including dissent. That's the opposite of a ban.
So you agree with Sabertooth, aem42290 and me that fresh raw animal carcasses obtained by Paleo HG's were not truly zero carb?There is no account for the glycerol that is released on fat breakdown being easily converted to glucose. There is no account for glycogen consumed in muscle and organ meats converting easily to glucose.
I've never in my life indulged in fresh vegetation myselfI too am interested in your input. Do you mean you've never eaten any fresh veggies for your entire life? What about non-fresh?
Nicola, could you PLEASE only post these absurd articles in the Hot Topics forum where they belong?! I'll move them there now.What would you guess was the % of calories as carbs in the diets of coastal northern Alaska Eskimos in the early 1970's, while they were still getting most of their food from hunting/fishing and before they moved into villages and started eating much more modern foods?
I think we all can agree there's really no ZERO carb diet.I hope so, and I hope that no one will use the term RZC or ZC to describe a RVLC diet they're following/promoting in the future. Let's leave that term to the coctivores at the ZIOH forum who seem to be the only ones really aiming for as close to ZC as they can get.
But rather diets that vary in the amount of carbs eaten along with varying amounts of fat and protein. How about moving on from this endless debate about ZERO carb and focus on what effects various levels of low carb have,, whether it be carb or 100 carb.Go ahead, shoot. What do you think the right intake of carbs is for you or in general, if any, and why?
I'm certainly not calling for the "banning" of the Carnivore subforum and don't want it to be banned. Like GS, I want to share and learn. I do agree with aem42290, Eric, Alive and Iguana that all civil perspectives should be allowed in all subforums, including dissent. That's the opposite of a ban.On the contrary, you were insisting that hysterical, science-free, dubious "warning" threads should be put in the RZC forum, but did not insist on other forums being so afflicted. That is almost as bad as banning a particular dietary path.

Interesting to see how Tyler responded to the article back then:
Organizing a virtual who’s who of low-carb diet research and practice, a review article published in the journal Nutrition and Metabolism last year attempted to come to a consensus on what constitutes a low-carb diet. You may recognize a few of the names featured on the expert panel shaping this definition: Dr. Richard Bernstein, Dr. Annika Dahlqvist, Dr. Richard Feinman, Uffe Ravnskov, Dr. Jeff Volek, Dr. Eric Westman, Dr. Jay Wortman and Dr. Mary Vernon, among many others.I wouldn't want to get into a debate over which figures to use. I do think it's helpful to see what others are using to give me a rough idea of what people mean.
...we have three distinct and practical terms and definitions to use now:
Low-carb ketogenic diet (LCKD): less than 50g carbs and 10% calories daily
Low-carb diet (LCD): 50-130g carbs daily and between 10-26% of calories
Moderate-carb diet (MCD): 130-225g carbs daily and between 26-45% of calories

]I just thought I'd do an experiment with various raw spices. Part of the problem I have, currently, is that while there are many raw animal food restaurants in London(ie Japanese Sashimi restaurants), it's more difficult to be raw when eating indoors. Being able to eat raw salads and occasionally using spices means I'm more used to eating like others. For example, using raw spices can help me overcome some of the disgusting taste of various cooked foods.That's actually slightly more negative about no-plant-food diets than I am even now (though only in the technical sense that if one had access to plentiful freshly-killed raw flesh richer in carbs and prebiotics than market foods, maybe especially from deep-diving sea mammals, it might be possible to fare rather well in the long run, but even that probably wouldn't be optimal and most of us don't have that access). Ironically, at the time I thought your warnings were a bit hysterical and I even followed with some questioning posts, but now I think they were largely on target and not really that excessive. I have since learned about many more people's negative experiences with ZC and near-ZC and some of them were very seriously bad indeed. No doubt you had seen many more such cases than I had at the time. I was even going to commend you for this a while back, but coincidentally right at that time you started writing more positively about ZC for some reason. Have you changed your mind and, if so, why?
As regards plants, I have had enough personal experience that makes it clear that raw plants, especially fruits, are essential for optimum human health, albeit in small quantities. No plant-food whatsoever in the diet, at best greatly reduces physical performance, and, for many people such as myself, it causes very terminal health-problems in the long run.
The topic of this thread, "Why a zero carb diet is not optimal for human health," may be a truth for people who are not sick to begin with, but I don't have great health, and low-carb has given me a tool to bring my health closer to normal.
Commonly, at around two years on the diet, or after six months of being seizure-free, the diet may be gradually discontinued over two or three months. http://en.wikipedia.org/wiki/Ketogenic_diet#Discontinuation (http://en.wikipedia.org/wiki/Ketogenic_diet#Discontinuation)Interestingly, two years is around the time it seems like that ZCers/near-ZCers tend to start to reporting problems and reintroducing carbs or prebiotics (and some last longer, of course). What is the record # of years in a row for someone doing ZC or near-ZC containing no plants at all?
Sabertooth, I think you said in the past that you eat Artisana coconut butter, which contains a bit of carbs. Do you eat any other plant foods that contain carbs?
Seizure disorders like epilepsy are indeed a popular use for VLC/ketogenic diets. Neurological disorders seem to benefit the most. Aren't those diets usually temporary, though, rather than long-term chronic? I found this:

What about fasting? Humans are known to be extremely well adapted to long periods of famine. The ketosis that goes along with this is a zero carb ketosis by default. The gut does just fine without any fiber to ferment and the gluconeogenesis and glycerol conversion are covering all brain needs for glucose. I beleive to get the best benefit from ketosis it should mimic the fasting state as close as possible with regard to macronutrients and even be alternated with 1-5 day fasts to get the added benefits of autophagyYes, intermittent fasting and intermittent ZCing do appear to be beneficial and none of my warnings were regarding it. They were regarding chronic long-term ZC.
Yes, the fact that fasting involving ketosis etc., such as intermittent fasting, is so healthy does mean that all those hysterical anti-RZC posts are nonsense.I do IFing and intermittent ZC myself. My posts had nothing to do with that.
And, even PP had to admit that aem was advocating a sticky warning thread. Such threads are tantamount to a ban and a waste of time.As I already pointed out, I didn't call for a sticky and don't want one, and you again ignored that aem offered it as one possible alternative along with another alternative.
On the contrary, you were insisting that hysterical, science-free, dubious "warning" threads should be put in the RZC forum, but did not insist on other forums being so afflicted. That is almost as bad as banning a particular dietary path.

In the end what is optimal is unique to the individual.
I'd like to continue this debate if you would indulge me, though in a more gentlemanly manner. I must say its been a while since I have researched any of this and its possible that there is new knowledge out there. This is one of those things where you can't just take any study and run with it because there are vested interests that like to fudge numbers and mislead people when health is at stake.
It is also clear from the evidence that HGs in palaeo times would have been forced to go RZC for lengthy periods due to Ice-Age conditions and seasonal variation.BTW, this ties in nicely with the topic of the Old Friends, prebiotics (like glycans) and probiotics. Scientists have been learning that one of the things that enables HGs to get through the winter with not a lot of plant foods is freezing and fermenting meats. Freezing preserves prebiotics and anaerobic fermentation actually promotes prebiotics, probiotics and carbs in meats, IIRC. This was discussed by DuckDodgers at the FTA blog links I provided in the past, such as the one in this post: http://www.rawpaleodietforum.com/hot-topics/the-zero-carb-myth-why-a-zero-carb-diet-is-not-optimal-for-human-health/msg122211/#msg122211 (http://www.rawpaleodietforum.com/hot-topics/the-zero-carb-myth-why-a-zero-carb-diet-is-not-optimal-for-human-health/msg122211/#msg122211)
Would you please stop making so many negative assumptions and ask me questions before jumping to such conclusions or if there's anything you don't understand, as I've asked you many times before? Please try to remember that you're a moderator who is supposed to set a positive example.This is just pure equivocation. More to the point, as a moderator, I have to make sure to criticise people for what they are actually attempting to do, rather than what they claim to be doing/meaning.
So do you still agree with this quote or not? It says "many people," so that should be OK, yes?*sigh* I just said that at the time I was on the defensive against pro-RZC proponents who were just as fanatical as your current anti-RZC stance, so the word "many" should really be "some", these days. Unlike people like you, I feel every type of diet should be given the same treatment. Posting dubious attack-threads in one forum, but not in others is misleading and actually quite dishonest and corrupt.
"No plant-food whatsoever in the diet, at best greatly reduces physical performance, and, for many people such as myself, it causes very terminal health-problems in the long run." http://www.rawpaleodietforum.com/journals/a-day-in-the-life-of-tylerdurden/msg12373/#msg12373 (http://www.rawpaleodietforum.com/journals/a-day-in-the-life-of-tylerdurden/msg12373/#msg12373)
Another source of glucose is Edogenous Glucose Production during fat metabolisation.
Fats are created with a glycerol backbone, and when fats are metabolised the glycerol molecules are released. Two glycerol molecules are easily combined to make a glucose molecule, which is way easier and cleaner than converting protein to glucose.
Typically about 12% of the calories from fat are provided as glucose, so if someone on 'ZC' was burning 2000 cal of fat they would get around 240 calories of this as glucose. I imagine one great thing about this source of glucose is that it will be released only slowly as the fat is used, compared to carb consumption where there is more of an uncontrolled explosion of glucose into the bloodstream.
Regarding a ketogenic diet, we can see already that a significant amount energy can be supplied to the brain by glucose from fat metabolisation. My understanding is that so long as protein consumption is moderated then ketones will be produced from fat to provide for the glucose deficit. Now it seems obvious that if a 'ZCer' can be getting hundreds of glucose calories from fat there will be little impact on their level of ketosis of adding a few tens of calories of carbs.
So while a 'ZC' diet is ketogenic, it does not follow that a ketogenic diet must be zero carb. There is a spectrum of ketosis depth which can be traded off against any benefits from some carb consumption.
Also if the generation of ketones for improved cognitive function is the goal then consuming short and medium chain fats are most beneficial. These can be found in coconut oil and are produced by gut bacteria when resistant starches are consumed.
So there we go - we have fats that make glucose and starches that make fat (via gut microbes).

Your gut bacteria will die off if you don't feed it sugar and your body will be unable to extract any nutrients from the raw meat you are eating and you will most likely experience other serious complications.

24isours, what is the reason that you avoid VLC plant matter, such as greens?

Posting dubious attack-threads in one forum, but not in others is misleading and actually quite dishonest and corrupt.Do you mean you exaggerated in the past? If so, how do I know you're not doing the same now? The "many" people you mentioned in the past would still be valid for you to indicate today, if you were not exaggerating then. Just because many of them are not active in this forum any more doesn't mean they didn't report problems in the past. If you should go inactive that wouldn't somehow invalidate the poor results you reported from RZC.
anyways though has anybody else here noticed any changes in daily fluid intake, since adapting raw VLC and/or seasonal diets?
Inger, I imagine that your diet is not all that high in fat as a percentage? But because you consume so much RAF it adds up to a nice lot of fat to provide a good base of slow release glucose? And then your metabolism must so efficient from having so many energetic but controllable electrons Krusing about that the excess proteins are easily used or disposed of ;)
Many of the bacteria are species that the researchers had never seen before. And even familiar microbes were present in unusual levels in the Hadza belly. “The Hadza not only lack the ‘healthy bacteria,’ and they don’t suffer from the diseases we suffer from, but they also have high levels of bacteria that are associated with disease,” Crittenden said.
been following the thread, and can see that much has already been discussed. yet one particular aspect of the opening post, hasn't seemed to have been discussed in any detail:
" the carnivorous ZC/ultra VLC diet typically calls for abhorrent amounts of daily fluid intake (wholly against what would be expected in a non-domesticated environment.) "
is it not something we can all agree upon, that humans seem to require more water compared to other comparably sized mammalian carnivores (or "omnivores" or whatever other moniker you choose)? granted of course you can get much fluids from a fresh kill...and it would be going a bit too far to claim that these "abhorrent amounts of daily fluid intakes" would be unrealistic in a natural environment, you know considering hunter-gatherers have been long surviving with such daily fluid requirements...but i digress

Thirst is a sign of diabetes, and monitoring my thirst levels was my primary way of monitoring my correct carb intake.
What does this tell us?
We probably know nothing about how a healthy gut flora have to look like....
aem42290, I do appreciate your specifying that it is that complete Raw Zero Carb or pure Carnivory that you are harping against and making it clear in this thread.
And I do appreciate other people chiming in with their experiences.
Let's all be welcoming to each other's sharing... we are a very small number of global practitioners and every experience counts.
So please don't "lose patience".
This is all good conversation.
Could be diabetes, certainly. But thirst may also indicate dehydration, which has a tendency to impact those on a sustained ZC diet. The kidneys become highly effective at excreting salts from the body while in very deep ketosis. For some folks, this is not a problem; they simply heighten their sodium intake to compensate for the problems, or add in magnesium supplements to mitigate the mineral losses. I, for one, was never interested in adopting a diet that demanded supplements in order to function effectively. My understanding is that a diet which requires supplementation (be this in the form of iodine pills, Amazonian minerals, magic joojoo pills, etc.) is a rather problematic diet to begin with.
This has to be one of the most biased, unscientific post I’ve read in a while.
“By and large, carnivorous mammals across the world exhibit lower average lifespans than omnivorous creatures.” Really? Please show any evidence of this.
And even if this was true, it means nothing about the validity of a diet to optimal health. Optimal health means heath level during life, not how long that life lasts.
Mice are herbivores, but they live less long than a cat that feeds on them, if they both die of old age.
The evolutionary ideas, while “somewhat” valid as empirical evidence (is there any evidence that animals in the wild tend to eat what is best for them?
However, no one knows what earlier humans ate. It’s all guesses and suppositions. They had element “X” in their environment, it’s edible, they probably ate it. Again, why would people assume that they would eat what is good for them rather then what they might stumble upon is beyond me.
Worse, using arguments of authority is dishonest. “reading up on a great deal of scientific studies and informal experiences” What’s that supposed to mean? Every doctor I’ve ever heard talk about nutrition…
The body does not tend towards an optimal state. It maintains a “minimal” state. Enough to not die, nothing more. Lie down in a bed for a few months, eating the best diet you can. Your bones will still end up brittle, your muscles will be almost inexistent. Even if you eat a lot of protein and fat. Why? Because your body does the least in can if it has the option.
So the fact that gluconeogenesis and ketosis are very inefficient (on a calorific) and taxing (on the organs) is irrelevant. That’s like saying that a jet is not optimal because it consumes too much energy and stresses its components, so a bicycle is better.
That’s like saying that a jet is not optimal because it consumes too much energy and stresses its components, so a bicycle is better.
If you are going to take your own arguments as a basis for optimal behavior, then you should be against exercise. After all, exercise is inefficient, it taxes many organs, including the heart, wastes energy, and produces many “dangerous” chemical reactions.
The very fact that gluconeogenesis is associated to cortisol levels should send up some red flags” So again, are you against exercise? Exercise is strongly associated to cortisol levels. Cortisol is associated with stress. Stress is good for the body. Absence of stress is bad. Why don’t you tell astronauts how the absence of stress on their joints is good for them?
Finally, telling people that they should seriously switch their diets if they start feeling sick is irresponsible. People get sick irrespective of their diets. You trying to be an authority on what people should or should not do is laughable.
I know I said finally, but I lied. Here is some pure wisdom: The true optimal form is to be dead. Then you consume nothing, you experience no stress, and you have no chance of having any disease.
But that is not what I want. I want to be as strong and vigorous as I can. I don’t seek to be free from pain and stress, I want for everything that doesn’t kill me to make me stronger. I don’t want an easy life, I want the strength to endure a hard one.
needless to say in the wild, most mammalian carnivores will not pass up the opportunity to consume carbs. of course this consumption is seasonal, and would be considered a "treat"
the way i look at it, i'm fine eating as many carbs as i could safely eat, without degenerative reactions and stressors to the body. in other words, how much carbs can the human body safely handle, without the insulin system being overtaxed hence diabetes, plaque formation in the arteries, weakened immune system,ect so on so forth? to what extent can the human body take advantage of this carbohydrate energy source, and suffer none or inconsequential side-effects?

Optimization involves the process of making something as effective, sustainable, and fully-functional as possible. The optimization of a system refers to the maximization of productivity and the minimization of refuse. In the context of my discussion, optimization is directly tied to temporal sustainability, and therefore, by extension, to life span.When ZCers force their bodies to follow the less efficient metabolic pathways of converting protein or ketones into energy, instead of the more easily metabolized carbs or butyrate (such as from prebiotic-fed bacteria), this produces more of the "refuse" you mentioned. Did you have lactic acid in mind?
"Free fatty acids suppress mitochondrial respiration (Kamikawa and Yamakazi, 1981), leading to increased glycolysis (and the production of lactic acid) to maintain cellular energy." http://www.abioenergeticview.com/2-2 (http://www.abioenergeticview.com/2-2)
"Butyrate pretreated cells displayed a modulation of glutamine metabolism characterized by an increased incorporation of carbons derived from glutamine into lipids and a reduced lactate production. The butyrate-stimulated glutamine utilization is linked to pyruvate dehydrogenase complex since dichloroacetate reverses this effect. Furthermore, butyrate positively regulates gene expression of pyruvate dehydrogenase kinases and this effect involves a hyperacetylation of histones at PDK4 gene promoter level. Our data suggest that butyrate exerts two distinct effects to ensure the regulation of glutamine metabolism: it provides acetyl coA needed for fatty acid synthesis, and it also plays a role in the control of the expression of genes involved in glucose utilization leading to the inactivation of PDC." Butyrate elicits a metabolic switch in human colon cancer cells by targeting the pyruvate dehydrogenase complex. http://www.ncbi.nlm.nih.gov/pubmed/20715114 (http://www.ncbi.nlm.nih.gov/pubmed/20715114)

“Defnitely I share Paul [Jaminet's] discomfort with very low carb diets especially over the long-term because when you go very very low carbohydrate, you tend to reduce leptin. And certainly when you start from a place of excessive leptin or leptin resistance, then it’s a good thing. That’s why people see benefits over the short term when they first adopt VLC diets or [Ketogenic Diet] approaches. But over the longterm the reduced leptin causes thymus atrophy and the thymus gland is crucial in the function of adaptive immune system because it’s the gland that matures T lymphocytes, which are huge components of the adaptive immune system.”

That's a fantastic question, Colorles. Personally, I now choose to consume around 75-80g of carbs per day (in the form of fruits and raw starches--definitely never any empty carbs), although this number fluctuates depending on daily exercise intensity. I seldom measure how many carbs I eat, unless I am engaged in an active experiment, or if my curiosity has been piqued by some readings. I believe that it was Alive that pointed me to Paul Jaminet's website (I thank him for this greatly). Jaminet states that in order to achieve optimal levels of metabolic flexibility, the inclusion of carbs in a diet should account for 20-30% of daily total caloric needs. Jaminet's number is a bit on the high end for my liking, and I have found that I am typically satisfied with 15-20% of my calories coming from healthy carbs.
I would definitely be curious to hear from others, though~
Do you mean you exaggerated in the past? If so, how do I know you're not doing the same now? The "many" people you mentioned in the past would still be valid for you to indicate today, if you were not exaggerating then. Just because many of them are not active in this forum any more doesn't mean they didn't report problems in the past. If you should go inactive that wouldn't somehow invalidate the poor results you reported from RZC.Like I said before, we cannot allow dissent as it is nearly always of the hysterical variety. More the point, interest in a wide variety of diets waxes and wanes with the advent of every new diet book or scientific finding. Such trivialities are not relevant to a particular diet which does not change so easily. Plus, the various dietary forums are small and are meant more for discussing aspects of that particular diet. Attacking those rawpaleo diets should, by contrast, go to the hot topics forum instead.
I agree w/ you that the subforum diets should be treated the same, which is why I asked that dissenting views be allowed in ALL the subforums.
I think it's obvious that humans are omnivores. I mean we have teeth(molars) designed for eating plants, plus amylase for starches etc.
The very fact that gluconeogenesis is associated to cortisol levels should send up some red flags: gluconeogenesis is tough work, and our bodies will avoid activating the metabolic pathway unless absolutely forced to do so
Thanks for acknowledging five years later that you were exaggerating back then. Maybe five years from now we'll learn what you're true current views are. ;D If you could unapologetically exaggerate back then as it suited your needs, you could do so again.Pathetic pedantry as I was being quite obvious re exaggeration way back when. Whatever the case, I will always defend this board from being overrun by hysterical science-free posts of the sort suggested. Plus we need to be fair to all and allow each forum to have a decent chance.
Did you respond about what you think the specific starchy foods were that humans have amylases for? Sorry if you did already, I don't remember a clear direct answer.A few raw tubers.
To those of you who think Gluconeogenesis requires high cortisol levels, read this:
http://www.ketotic.org/2012/07/ketogenic-diets-and-stress-part-i.html (http://www.ketotic.org/2012/07/ketogenic-diets-and-stress-part-i.html)
A few raw tubers.Amylase for tubers, eh? Based on ZC guru Bear Stanley's writings, I'll bet he wouldn't agree:
Could be diabetes, certainly. But thirst may also indicate dehydration, which has a tendency to impact those on a sustained ZC diet. The kidneys become highly effective at excreting salts from the body while in very deep ketosis.

My understanding is that a diet which requires supplementation (be this in the form of iodine pills, Amazonian minerals, magic joojoo pills, etc.) is a rather problematic diet to begin with.
On numerous occasions, my heart problems on a ZC diet were attributed to "dehydration." In response to those statements, I thought: complete BS, considering that I was consuming a large amount of water throughout my waking hours. However, one should realize that larger amounts of water don't precisely add up to adequate hydration. In fact, drinking multiple liters a day when the body is in a deep ketogenic state may exacerbate the loss of electrolytes by accelerating excretory processes.
You are foolishly misconstruing my arguments. I am not claiming that short-term stressors are unnecessary for human health; I am writing against the long-term stressors emerging from a chronic ZC diet and its inefficient metabolic pathways. The reason why cortisol sends up a red flag in relation to gluconeogenesis is because while in a deep ketogenic diet, a subject is constantly engaged in gluconeogenesis, and therefore exhibits elevated cortisol levels (Swain et al. 2012). Dichotomizing stress as good/bad is a ridiculous proposition. Stress is neither good nor bad; stress is a physical signifier that directs our attention toward bodily processes that may indicate the absence or presence of particular adaptive mechanisms. I have opted to question which adaptive mechanisms are optimal for both longevity and maximum health.
aem42290,
I am wondering if you gained benefits initially from VLC that were worthwhile, and if you had started to very slowly increase carbs early on that might have worked well?
I have been interested in reading the research of Paul and Shou-Ching Jaminet (The Perfect Health Diet book). In regards to carbs their findings are that the ideal is 30% of energy from carbs (Typically ~600 calories), from 'safe starches' like potatoes, rice and bananas, to provide for the bodies glucose needs, and the rest from fat.
Here is Paul's investigation of ideal glucose levels for longevity and dialog with Ron Rosedale:

banana(its like eating white sugar)
... Speaking of the Bear, the forum where he first spread the word on his version of ZC carnivory and sparked the ZC phase is another example of the decline of ZC - the forum is nearly moribund, with no posts since January: http://activenocarber.myfreeforum.org/index.php (http://activenocarber.myfreeforum.org/index.php)It seems the Zeroiningonhealth zero carb forum of Charles Washington that was inspired by Bear Stanley has also been defunct since some time before 19 Jan 2014: http://forum.lowcarber.org/archive/index.php/t-457723.html (http://forum.lowcarber.org/archive/index.php/t-457723.html)
