As the implications of the Warburg effect in health and disease continue to emerge, we are entering into a renaissance period for metabolism research. Since the Warburg's original observation, we have learnt a lot about the effect of signal transduction on metabolic pathways and how cells rapidly reprogram their metabolism although much remains to be discovered.
From this review, we found further evidence that ketogenic diet in cancer patients is safe and feasible as an adjuvant therapy. As described above, we could conclude that in order to see any significant progression or improvement by ketogenic diet, at least 3 to 4 weeks of ketogenic diet is required. Additionally, we suggest that not only body composition but also biomarker or measures for tumor size or tumor metabolism assessment is essential. We also conclude that the acceptability for ketone diet may be better in some cancer type (better in glioblastoma than gastric cancer).
The rationale of KD is valid both because it lowers carbohydrate uptake possibly leading to cancer cell starvation and apoptosis and, at the same time, increases the levels of ketone bodies available for energy production in normal cells but not in cancer cells which have an allegedly downregulated oxidative phosphorylation.
The ketogenic diet probably creates an unfavorable metabolic environment for cancer cells and thus can be regarded as a promising adjuvant as a patient-specific multifactorial therapy. The majority of preclinical and several clinical studies argue for the use of the ketogenic diet in combination with standard therapies based on its potential to enhance the antitumor effects of classic chemo- and radiotherapy, its overall good safety and tolerability and increase in quality of life. However, to further elucidate the mechanisms of the ketogenic diet as a therapy and evaluate its application in clinical practice, more molecular studies as well as uniformly controlled clinical trials are needed.
Abstract
Ketogenic diets (KDs) are emerging as effective therapies for several chronic diseases, including cancer. However, concerns regarding safety and adherence may prevent clinicians from prescribing KDs. We hypothesized that a KD does not negatively affect blood lipid profile compared to a lower-fat diet in ovarian and endometrial cancer patients, and that KD subjects would demonstrate acceptable adherence. Subjects were randomized to either a KD (70% fat, 25% protein, 5% carbohydrate), or the American Cancer Society diet (ACS; high-fiber and lower-fat). Blood lipids and ketones were measured at baseline and after 12 weeks of the assigned intervention. Adherence measures included urinary ketones in the KD and 4 days' diet records. Diet records were also examined to identify general patterns of consumption. Differences between the diets on blood lipids and dietary intake were assessed with Analysis of covariance and independent t-tests. Correlation analyses were used to estimate associations between dietary intake and serum analytes. At 12 weeks, there were no significant differences between diet groups in blood lipids, after adjusting for baseline values and weight loss. Adherence among KD subjects ranged from 57% to 80%. These findings suggest that KDs may be a safe and achievable component of treatment for some cancer patients.
First clinical pilot studies on the KD and cancer have been conducted,7,10, 11, 12, 13, 14 and several others are planned or currently running.15, 16, 17 These studies are based on mainly three rationales.18 First, KDs have been shown to be capable of slowing down tumor growth in many, although not all, animal models.18,19 Second, the replacement of carbohydrates with fat that is characteristic for a KD is supposed to account for the increased fat oxidation rates in cancer patients that are due to tumor-induced insulin resistance, in this way possibly protecting against skeletal muscle loss.20, 21, 22 Third, KDs are expected to sensitize tumor cells to radio- and chemotherapy, principally opening up a very broad range of applications as complementary cancer treatments. This at least partly relates to their ability to impair tumor cell glycolysis, reducing ATP levels and the ability to utilize substrates of glycolytic metabolism for protection against reactive oxygen species.23, 24, 25
Abstract
PURPOSE OF REVIEW:
Altered glucose metabolism in cancer cells is an almost ubiquitous observation, yet hardly exploited therapeutically. However, ketogenic diets have gained growing attention in recent years as a nontoxic broad-spectrum approach to target this major metabolic difference between normal and cancer cells. Although much research still needs to be done, new knowledge has been gained about the optimal utilization of ketogenic diets for cancer treatment that this review aims to summarize.
RECENT FINDINGS:
Although most preclinical studies indicate a therapeutic potential for ketogenic diets in cancer treatment, it is now becoming clear that not all tumors might respond positively. Early clinical trials have investigated ketogenic diets as a monotherapy and - while showing the safety of the approach even in advanced cancer patients - largely failed to prove survival prolonging effects. However, it gradually became clear that the greatest potential for ketogenic diets is as adjuvant treatments combined with pro-oxidative or targeted therapies initiated in early stages of the disease. Beneficial effects on body composition and quality of life have also been found.
SUMMARY:
Ketogenic diets against cancer are worth further exploration, both in the laboratory and clinically. Patients wishing to undertake a ketogenic diet during therapy should receive dietary counselling to avoid common mistakes and optimize compliance. Future research should focus more on important clinical endpoints.
More recently, however, preclinical research suggests that the potential mechanism of ketosis on cancer cells does not rely solely on the Warburg effect. The spectrum of altered growth, metabolism, and signaling metabolites incurred by ketosis may result in a cancer cell–specific induction of oxidative stress, thereby potentiating the effect of chemotherapy and radiation.[34,35] Additionally, ketogenic diets may have a protein-sparing effect that preserves lean body mass in the setting of cancer cachexia.[36] In animal models, ketogenic diets decrease the initiation, progression, and metastasis of cancer.[37]
Evidence in human clinical trials is limited to cases and small open-label studies, typically as salvage therapies, which confirm the feasibility and safety of ketogenic diets. These studies suggest that ketogenic diets are safe, and do not negatively impact quality of life. They are, however, difficult to adhere to, and many patients do not reach desired levels of ketones in the urine.[35,38-41] The bottom line is that ketogenic diets may have utility in certain individuals, especially in combination with other conventional therapies, but there is currently no reliable way to predict which patients might respond. They are exceedingly difficult to implement without professional dietary counseling. Moreover, poorly implemented ketogenic diets incur risk for micronutrient deficiency; are very high in saturated fat; are typically low in fiber; may include processed foods; and may exclude entire food groups, such as fruits, legumes, and many vegetables, which have been shown to be beneficial for cancer prevention and mortality (See Figure).
There are both in vitro and in vivo animal studies to suggest that KD has the potential to augment the treatments currently available for patients with aggressive gliomas. The value of KD to treat humans with these malignancies has yet to be proven in clinical trials. There is currently a lack of standard KD protocols so that comparison of different trials is difficult. Rigorous diet management and objective measures of ketosis are required to fairly evaluate the effectiveness of the KD as therapy for aggressive gliomas.
In conclusion, clinical application of KDs as an adjuvant therapy for cancer patients first requires that the KD be evaluated for its anti-tumor effect for each single type/genetic subtype of cancer in a preclinical setting, as the safety and efficacy of the KD strongly depend on the tumor entity and its genotype. Based on the results of rigorous preclinical and clinical studies performed thus far, the KD would appear to be a promising and powerful option for adjuvant therapy for a range of cancers. Cancer-specific recommendations await the findings of randomized controlled clinical trials.
Data from case reports and trials suggest KD use is safe and tolerable for patients with cancer. Although it would be ideal to conduct a larger trial using a randomized therapeutic approach, the current emphasis on drug-based trials is a formidable obstacle. Other major obstacles are patient initiative and adherence. For now, investigators must work with anecdotal data. Examination of gene expression patterns in mitochondria and mutations in ketolytic and glycolytic enzymes may prove useful in selecting potentially responsive patients. Combining this dietary approach with standard chemotherapeutic and radiotherapeutic options may help improve tumor response, and further research is desperately needed.
Fuck this. You have now really, really crossed a line IMO.

Myth: People with cancer shouldn't eat sugar, since it can cause cancer to grow faster.
Fact: Sugar doesn't make cancer grow faster. All cells, including cancer cells, depend on blood sugar (glucose) for energy. But giving more sugar to cancer cells doesn't speed their growth. Likewise, depriving cancer cells of sugar doesn't slow their growth.
This misconception may be based in part on a misunderstanding of positron emission tomography (PET) scans, which use a small amount of radioactive tracer — typically a form of glucose. All tissues in your body absorb some of this tracer, but tissues that are using more energy — including cancer cells — absorb greater amounts. For this reason, some people have concluded that cancer cells grow faster on sugar. But this isn't true.
However, there is some evidence that consuming large amounts of sugar is associated with an increased risk of certain cancers, including esophageal cancer. It can also lead to weight gain and increase the risk of obesity and diabetes, which may increase the risk of cancer.
'A couple of hours on pub med'? How many of those articles have you properly vetted?
Hell a few seconds on Google puts the lies above to rest.
I know CarbShark is as bad as an evangelical when it comes to his food beliefs. They are just as crazy as believing the world is flat.
But with the above spew of bullshit, he's gone to a new level of being a danger to people. He's now the equivalent of Stanislaw Burzynski.
If you're not familiar withDr.Burzynski, he's the guy that gets desperately ill people to come to Texas to be injected with animal piss to cure their cancer.
CarbShark is now inviting desperately ill people to stop their glucose intake, which will do nothing but harm to them.What harm?

That position is more conservative than the mainstream and he’s got a couple facts wrong. The theory is based on the Warburg effect that goes back decades before PET scans.
And, yes, all cells in the body can burn glucose and do burn glucose if other fuels are not readily available, if glucose is low and ketones are present many cells will burn ketones instead of glucose. Further, cells can be insulin sensitive, meaning they put out insulin receptors to take in more glucose. Cancer cells are highly insulin sensitive and put out more insulin receptors than most normal cells. The hypothesis is that with high blood glucose levels cancer cells have an unlimited supply of energy. Lower glucose levels limit the supply.QuoteHere's further evidence against CarbShark's self selected and cherry picked list above. Lets ask an oncologist whether or not keto can cure cancer:

I read them both, of course. Did you read any of the articles I linked to?
I am not arguing, and none of the papers cited are arguing, that keto is better than or should be used instead of standard therapies.
It is being investigated as a complimentary therapy.QuoteI've been on this forum since 2007. This is the most irresponsible bullshit I've ever seen posted here and CarbShark should be ashamed of himself for advocating the equivalent of anti-vax crap here.
Again you can’t argue against the merits of the claim so you lump it in with you favorite villain. Bull shit.
And if you think I’m cherry-picking that shows first you haven’t read any of the articles or even just the abstracts, and it implies that there are far more articles on PubMed that dispute or contradict the claim.
There are not, but go ahead and look for yourself.

You certainly fulfill my definition of a proselytiser for your low carbohydrate/high fat ketogenic diet when you admit that you promote it unasked.
Are you certain that your diet wouldn’t harm people who are already sick from cancer? You did read the dietary advice from the MD Anderson Cancer Center (one of America’s premier cancer hospitals) which noted that some cancers grow faster with high fat diets?
Even if some cancers are dependent on glucose for metabolism and survival, even on a low carbohydrate ketogenic diet, there’s still glucose circulating in the bloodstream. Glucose dependent tumour cells are still going to get their glucose regardless.
Actually, in your notorious block dumped articles, there was one which referred to a case series of 2 from the early 20th century concerning 2 women with cancer who were given an insulin overdose in order to treat a psychiatric disorder, which apparently caused the cancers to regress. My comments concerning this are: 1. There’s a difference between a low carbohydrate diet and deliberately inducing a hypoglycaemic coma with an overdose of insulin. 2. The patients might not have had cancer in the first place.
Even if your diet has a beneficial effect in some cancers, it’s likely to be similar to chemotherapy.
Cancers as they progress develop a plethora of mutations progressively with the formation of numerous clones of cancer cells, some dividing faster, some spreading more quickly, some more dependent on glucose, some less, etc. As with cancer chemotherapy, if your diet is effective, it will kill the most susceptible cancer cells, reducing the cancer burden, but leaving the resistant cancer cells, which will then grow and divide, reforming the original tumour mass. Like chemotherapy, your diet might add a little time. Perhaps a few months.
As I’ve noted, by the time a cancer is apparent, it’s already around 3/4 along its course from initiation to death, by which time it’s not just one cancer, it’s many.
It would be more useful to prevent cancers before they actually develop, or at least in their very early stages. Your diet could prevent cancer, but the long term studies necessary to know just aren’t available, a point I’ve made to you repeatedly in response to your proselytising.

Medical advice is the provision of a formal professional opinion regarding what a specific individual should or should not do to restore or preserve health.[1] Typically, medical advice involves giving a diagnosis and/or prescribing a treatment for medical condition.[2]
Medical advice can be distinguished from medical information, which is the relation of facts. Discussing facts and information is considered a fundamental free speech right and is not considered medical advice. Medical advice can also be distinguished from personal advice, even if the advice concerns medical care.

From my reading of some clinicians, a ketogenic diet is a helpful adjunct to conventional therapy for some cancers.
Overweight and obese women are more at risk of breast cancer than lean women. The standard american diets, high in processed carbs is very likely to add to the size and number of ones fat cells. I would add there is evidence that the high fraction of calories in the SAD diet from PUFAs might also increase the risk.

You can go around and around with a tireless rebutter for years (we literally have) but as long as disagreement is voiced then we have done what we are here to do.
What skeptics should be doing is actually looking at the information provided, doing their own research, and discussing the merits of the approach.This is the problem. People "doing their own research" is how you get crackpots. Skeptics don't do research. They listen to the experts, actual members of the scientific community.

What skeptics should be doing is actually looking at the information provided, doing their own research, and discussing the merits of the approach.This is the problem. People "doing their own research" is how you get crackpots. Skeptics don't do research. They listen to the experts, actual members of the scientific community.
You are not "doing your own research." You are not qualified to do nutritional research. You are just seeking out articles and trials that reinforce your bias, misunderstanding them or reading spurious ones. People "doing their own research" can derive any effect they want from any body of study they can find. This is just not how skepticism (or science, for that matter) works.
I'm not sure how you think this is related to what I said. Whatever the mainstream position might be, or the value of any non-mainstream positions, you are not qualified.
Skepticism does not end at the mainstream position.
And answer my questions. What type of cancers do your two friends have? Where are the studies showing the efficacy of your diet in their specific cancers?
Nope. Not answering any of your questions as long as you keep mischaracterizing what I am doing. I am not offering medical advice.
I suspect you keep making that accusation as you have a tendency to troll, and I'm not interested in playing along.
I’m not mischaracterising what you’re doing. I’ll quote you from your first comment on this thread:
‘I have two close friends who have cancer now, one of them has known me since before I was a LCHF dieter, back when I was obese. So I’m going to share this with him. He’s fairly sceptical, and may dismiss it out of hand, but I would feel terrible if I did nothing, and then better studies start showing a beneficial effect while his cancer progresses. (He’s doing chemo and after some progress his tumors have started growing again.)
You’re providing medical advice. You didn’t write ‘should I provide the information?’ And you don’t have any knowledge about whether your diet actually has any efficacy in the specific cancers your friends have. Your friends might be coming to harm if they have the specific cancers made worse by high fat diets.
I’m not trolling when I ask for evidence. I’d be trolling if I provided unsupported assertions, as you do with your quasi-religious ideologically biased diet preference.
This thread is beyond the pale.
This is no different to anyone else showing up out of the blue to promote woo.
Tackling this kind of thing is what we do.
I think anyone reading this thread to see the viability of such a diet for treating cancer would come away under no illusions as to what is the takeaway of most skeptics.
You can go around and around with a tireless rebutter for years (we literally have) but as long as disagreement is voiced then we have done what we are here to do.

If the studies exist, then the results should be reasonably clear cut. Survival should be increased significantly by months, or better still, years.

What you're doing is not research.
You're just Googling PubMed for research papers, cherry-picked according to their titles or conclusions.
Then you're copy-pasting masses of links to those papers on a general interest Web forum which is not populated by medical experts. Then you're asserting that this highly technical information represents evidence to support your own opinion.
That is, at best, a fringe opinion which runs contrary to the general consensus of the worldwide medical establishment.
You are not a doctor, a biologist, a dietitian, or even a medical researcher.
You're a layman with an Internet connection.
In "evaluating" these studies you lack the requisite education, skills, and medical industry experience to fully understand the procedural methodology and statistical analysis, let alone the professional reputations of the authors and publishers of the studies.
By blindly mass-posting links to highly technical medical studies on a Web forum for non-medical professionals, what you're doing is a virtual Gish gallop. It's a form of burden-shifting to assert that these studies prove you're right and defy everybody else make sense of them when you clearly don't understand them yourself.
In short, you're working backwards from a preferred conclusion, seeking to legitimize your own preconceived opinion on an open Web forum.
That's not research. It's just an amateur tactic for promoting pseudoscience.

OK, Fine, show me a definition of medical advice (not just one you pull out of your ass) that covers this and we'll talk.
Also, when I looked up the definition for research, the one I posted was the first one that came up and the next two were basically the same.
How many results did BF have to go through before finding one that was exclusive?
And at the same time they accuse me of cherry picking.
WHY LAY PEOPLE SHOULD NOT DISPENSE MEDICAL ADVICE:
It's inappropriate for lay persons to recommend and actively promote medical practices (standard, investigational, or alternative) as recipes for survival to other patients for the following reasons:
(1) Each lymphoma (even if of the same diagnosis) can be unique clinically, such as:
growth rate, sensitivity to treatments, location near vital organs, bone marrow involvement, and so on.
(2) The biology of the lymphoma and the patient can have unique characteristics that will result in very different clinical courses, and responses to the same treatments. For example, normal genetic variations in an individual's immune system may influence the response to Rituxan.
(3) Each case can be unique, such as the patient's age, general health, symptoms, blood counts, treatment history, risk tolerance, secondary medical conditions, and access to therapies.
(4) By definition, lay persons are not medical professionals and are likely to have gaps in knowledge.
(5) Even a medical professional will not, and ought not, dispense medical advice without directly examining the patient, and having access to the complete medical history, the details of the diagnosis, the most current lab results, imaging reports, and so on.
The clinical judgment of trained oncologists, and the specialists we consult, are essential to the treatment decision process. Ideas or suggestions by lay persons may be considered of course ...however, at best, these should be considered merely starting points for discussions with your doctors.

The patient selects the strategies, which are reported to be based on scientific studies.

The layperson concludes that there is no harm when the treatment or life style strategy is safe.
Complementary Medicine:Emphasis added
Changing your life style in reaction to a diagnosis of lymphoma is most likely considered complementary practices. Clearly it's both sensible and beneficial to eat healthy foods, to exercise routinely (within your limits), get adequate sleep, and so on. Good performance status is correlated with improved survival in lymphomas. However, at this time there is no evidence that exercise, diet, or herbs can directly affect the course of the disease.

This is a topic that's important enough to me that I think it merits its own thread.
Based on the idea that cancer cells rely primarily and in some cases exclusively on glucose for energy (the Warburg effect) the idea of using carbohydrate restriction to fight cancer along with traditional methods (chemo; radiation; surgery) has gotten a lot of traction lately and shown significant promise.
But, there have not been enough studies to clearly show its effectiveness (or lack thereof) but there is very little or no evidence that it causes harm.
I have two close friends who have cancer now, one of them has known me since before I was a LCHF dieter, back when I was obese.
So I'm going to share this with him. He's fairly skeptical, and may dismiss it out of hand, but I would feel terrible if I did nothing, and then better studies start showing a beneficial effect while his cancer progresses. (He's doing chemo and after some progress his tumors have started growing again).
So here's what I found in a couple hours on pub med. I've read all the abstracts and will read the full text of as many as I can in the days to come.

Additionally, we suggest that not only body composition but also biomarker or measures for tumor size or tumor metabolism assessment is essential. We also conclude that the acceptability for ketone diet may be better in some cancer type (better in glioblastoma than gastric cancer).

Ketogenic diet in the treatment of cancer – Where do we stand?
Author links open overlay panelDaniela D.WeberSepidehAminzadeh-GohariJuliaTulipanLucaCatalanoRené G.FeichtingerBarbaraKoflerQuoteThe ketogenic diet probably creates an unfavorable metabolic environment for cancer cells and thus can be regarded as a promising adjuvant as a patient-specific multifactorial therapy. The majority of preclinical and several clinical studies argue for the use of the ketogenic diet in combination with standard therapies based on its potential to enhance the antitumor effects of classic chemo- and radiotherapy, its overall good safety and tolerability and increase in quality of life. However, to further elucidate the mechanisms of the ketogenic diet as a therapy and evaluate its application in clinical practice, more molecular studies as well as uniformly controlled clinical trials are needed.

A Ketogenic Diet Is Acceptable in Women with Ovarian and Endometrial Cancer and Has No Adverse Effects on Blood Lipids: a Randomized, Controlled Trial.
Cohen CW1, Fontaine KR2, Arend RC3,4, Gower BA1.QuoteAbstract
Ketogenic diets (KDs) are emerging as effective therapies for several chronic diseases, including cancer. However, concerns regarding safety and adherence may prevent clinicians from prescribing KDs. We hypothesized that a KD does not negatively affect blood lipid profile compared to a lower-fat diet in ovarian and endometrial cancer patients, and that KD subjects would demonstrate acceptable adherence. Subjects were randomized to either a KD (70% fat, 25% protein, 5% carbohydrate), or the American Cancer Society diet (ACS; high-fiber and lower-fat). Blood lipids and ketones were measured at baseline and after 12 weeks of the assigned intervention. Adherence measures included urinary ketones in the KD and 4 days' diet records. Diet records were also examined to identify general patterns of consumption. Differences between the diets on blood lipids and dietary intake were assessed with Analysis of covariance and independent t-tests. Correlation analyses were used to estimate associations between dietary intake and serum analytes. At 12 weeks, there were no significant differences between diet groups in blood lipids, after adjusting for baseline values and weight loss. Adherence among KD subjects ranged from 57% to 80%. These findings suggest that KDs may be a safe and achievable component of treatment for some cancer patients.
Wilhelm Brünings' forgotten contribution to the metabolic treatment of cancer utilizing hypoglycemia and a very low carbohydrate (ketogenic) diet (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6544614/)QuoteFirst clinical pilot studies on the KD and cancer have been conducted,7,10, 11, 12, 13, 14 and several others are planned or currently running.15, 16, 17 These studies are based on mainly three rationales.18 First, KDs have been shown to be capable of slowing down tumor growth in many, although not all, animal models.18,19 Second, the replacement of carbohydrates with fat that is characteristic for a KD is supposed to account for the increased fat oxidation rates in cancer patients that are due to tumor-induced insulin resistance, in this way possibly protecting against skeletal muscle loss.20, 21, 22 Third, KDs are expected to sensitize tumor cells to radio- and chemotherapy, principally opening up a very broad range of applications as complementary cancer treatments. This at least partly relates to their ability to impair tumor cell glycolysis, reducing ATP levels and the ability to utilize substrates of glycolytic metabolism for protection against reactive oxygen species.23, 24, 25

PURPOSE OF REVIEW:
Altered glucose metabolism in cancer cells is an almost ubiquitous observation, yet hardly exploited therapeutically. However, ketogenic diets have gained growing attention in recent years as a nontoxic broad-spectrum approach to target this major metabolic difference between normal and cancer cells. Although much research still needs to be done, new knowledge has been gained about the optimal utilization of ketogenic diets for cancer treatment that this review aims to summarize.
RECENT FINDINGS:
Although most preclinical studies indicate a therapeutic potential for ketogenic diets in cancer treatment, it is now becoming clear that not all tumors might respond positively. Early clinical trials have investigated ketogenic diets as a monotherapy and - while showing the safety of the approach even in advanced cancer patients - largely failed to prove survival prolonging effects. However, it gradually became clear that the greatest potential for ketogenic diets is as adjuvant treatments combined with pro-oxidative or targeted therapies initiated in early stages of the disease. Beneficial effects on body composition and quality of life have also been found.
SUMMARY:
Ketogenic diets against cancer are worth further exploration, both in the laboratory and clinically. Patients wishing to undertake a ketogenic diet during therapy should receive dietary counselling to avoid common mistakes and optimize compliance. Future research should focus more on important clinical endpoints.
Pros and Cons of Dietary Strategies Popular Among Cancer Patients | Cancer Network (https://www.cancernetwork.com/dietary-strategies-cancer)QuoteMore recently, however, preclinical research suggests that the potential mechanism of ketosis on cancer cells does not rely solely on the Warburg effect. The spectrum of altered growth, metabolism, and signaling metabolites incurred by ketosis may result in a cancer cell–specific induction of oxidative stress, thereby potentiating the effect of chemotherapy and radiation.[34,35] Additionally, ketogenic diets may have a protein-sparing effect that preserves lean body mass in the setting of cancer cachexia.[36] In animal models, ketogenic diets decrease the initiation, progression, and metastasis of cancer.[37]
Evidence in human clinical trials is limited to cases and small open-label studies, typically as salvage therapies, which confirm the feasibility and safety of ketogenic diets. These studies suggest that ketogenic diets are safe, and do not negatively impact quality of life. They are, however, difficult to adhere to, and many patients do not reach desired levels of ketones in the urine.[35,38-41] The bottom line is that ketogenic diets may have utility in certain individuals, especially in combination with other conventional therapies, but there is currently no reliable way to predict which patients might respond. They are exceedingly difficult to implement without professional dietary counseling. Moreover, poorly implemented ketogenic diets incur risk for micronutrient deficiency; are very high in saturated fat; are typically low in fiber; may include processed foods; and may exclude entire food groups, such as fruits, legumes, and many vegetables, which have been shown to be beneficial for cancer prevention and mortality (See Figure).

Investigating the Ketogenic Diet As Treatment for Primary Aggressive Brain Cancer: Challenges and Lessons Learned (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5834833/)QuoteThere are both in vitro and in vivo animal studies to suggest that KD has the potential to augment the treatments currently available for patients with aggressive gliomas. The value of KD to treat humans with these malignancies has yet to be proven in clinical trials. There is currently a lack of standard KD protocols so that comparison of different trials is difficult. Rigorous diet management and objective measures of ketosis are required to fairly evaluate the effectiveness of the KD as therapy for aggressive gliomas.
Ketogenic diet in cancer therapy (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5842847/)QuoteIn conclusion, clinical application of KDs as an adjuvant therapy for cancer patients first requires that the KD be evaluated for its anti-tumor effect for each single type/genetic subtype of cancer in a preclinical setting, as the safety and efficacy of the KD strongly depend on the tumor entity and its genotype. Based on the results of rigorous preclinical and clinical studies performed thus far, the KD would appear to be a promising and powerful option for adjuvant therapy for a range of cancers. Cancer-specific recommendations await the findings of randomized controlled clinical trials.

Ketogenic Diets and Cancer: Emerging Evidence (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6375425/)QuoteData from case reports and trials suggest KD use is safe and tolerable for patients with cancer. Although it would be ideal to conduct a larger trial using a randomized therapeutic approach, the current emphasis on drug-based trials is a formidable obstacle. Other major obstacles are patient initiative and adherence. For now, investigators must work with anecdotal data. Examination of gene expression patterns in mitochondria and mutations in ketolytic and glycolytic enzymes may prove useful in selecting potentially responsive patients. Combining this dietary approach with standard chemotherapeutic and radiotherapeutic options may help improve tumor response, and further research is desperately needed.

"One promising area for treating cancer is using a strict keto diet to lower blood sugar, and give cancer cells less fuel. Using Keto together with the regular treatments (radiation; chemo; surgery; etc.) is being studied right now and the results so far are promising but nothing conclusive. Here's all the information I have on it (including some information about your specific cancer), maybe it's something to talk to your doctor about."
You originally wrote ‘So I’m going to share this (information) with him.’ Nothing conditional. Now you’ve retreated to ‘were I to have this conversation with either of my friends battling cancer it would be along the lines of...’
You claim that you have ‘some information about your specific cancer.’ So which is it? I hesitate to do it, but please link to the information you have, so we can see if your ideologically biased diet actually has been shown to have efficacy in the specific cancers concerned. And summarise the information so we can see if you understand what you’re reading.
That's not a retreat. I initially said I would discuss it, later I described what I would say.
I would rather the conversation stayed on cancer and the potential for diet to help standard treatments than do your research for you so you make some claim about reading comprehension (especially you).
This kind of irrational and unproductive quibbling is why I don’t entertain trolls

I’m not certain whether adopting a fad diet such as a low carbohydrate/high fat ketogenic diet would add to a cancer sufferer’s mental burden (it might be of slight benefit in giving the cancer sufferers the illusion that they’re doing something of their own volition instead of nothing), but it would certainly add to their physical burden, while probably doing nothing to the cancer, and possibly be of slight benefit and also possibly cause the cancer to thrive more.

The above is a very good point: Someone with cancer is likely to be pestered by every friend, relative, and acquaintance with a crackpot "cure," all of them telling the sick person, "Well, then, if you won't take my advice it's your own fault if you die." I'm sure CarbShark won't say such a thing overtly, but the implication is there.
There is no one-size-fits-all cancer treatment. Every kind of cancer is different and every individual is different, and it is just preposterous to go around saying that any one diet is appropriate for cancers across the board, or that one particular diet "can't hurt you."
It is irresponsible in the extreme to go about peddling advice for cancer patients. Better to ask your friend "What can I do to help you?" or tell them "I'm here if you need anything." Or donate to institutions that are actually doing research.

Another is the one guy is a good friend and I’d fear doing this could damage our friendship.
The other friend is being bombarded by all sorts of woo, including people telling her to avoid chemo. I’d be more inclined to share this with her because at least it doesn’t interfere with her treatment.

Here you've made an error in logic that, in any other arena except LCHF diet, you'd have recognized and correctly denounced: You state that a diet high in carbs, especially refined fast and simple carbs, is bad for you, and from that you leap to adopting and advocating a diet that completely or nearly eliminates all carbs, including the healthy complex ones.
You are adopting the illogic that says "If too much of X is bad for you, then eliminating X entirely must be good for you.
There are many nutrients that are absolutely essential for health, or even for life, but which make you sick or even kill you in excess. Carbs in excess are unhealthy. Complex carbs in moderation are an excellent source of energy and often come with important other nutrients.
Other examples include sodium and vitamin A. Necessary for life; very bad in excess.
You're smart enough to see this, but for some reason you have a blind spot with regard to carbs.
And you've gone off the deep end when you pass from eliminating carbs for weight loss, to advocating the elimination of carbs to cure a wide variety of unrelated illnesses.
One of the most reliable indicators of a quack is when they claim their treatment cures a variety of unrelated illnesses or conditions.
... One of the most reliable indicators of a quack is discounting published studies in reputable peer review literature
...I’m not sure what point you’re making. But a meat based LCHF diet with 20g of complex carbs per day provides all the nutrition needed

Basically, you are claiming that you are better able to understand the totality of research on nutrition than people who have studied for years to become medical professionals.

I was making the point that just because too much of something can kill you, does not necessarily mean it should be eliminated. And yes, limiting carbs to 20 grams per day means that you are virtually eliminating them. Carbs are an excellent source of energy and other nutrients. Too much carb will make you fat, and too much simple carb increases your risk of diabetes. That does not mean you need to limit carbs to 20 grams per day. That is your logical error. One of them, anyway.
Yes, you can live on a nearly 100% meat diet. If you don't give a damn about the environment or the massive suffering such a diet entails.

But Daniel, you just don't understand. Modern dietary science is not supported by evidence (https://sguforums.com/index.php/topic,49787.msg9552495.html#msg9552495), and the USDA recommended dietary guidelines are actually a global conspiracy orchestrated by the US government (https://sguforums.com/index.php/topic,49787.msg9552609.html#msg9552609), which dictates the food policies of the UN and the WHO, and several other countries (https://sguforums.com/index.php/topic,49787.msg9552813.html#msg9552813).Yes, you can live on a nearly 100% meat diet.

With enough rigorous questioning, woo promoters usually resort to conspiracism at some point.

... for the medical community in general, nutrition is not that big of a deal.

Nutrition is not taught in medical schools; there is no recognized specialty for nutrition; the mainstream guidelines offer very little guidance on nutritional issues; there is limited funding for nutrition research.... for the medical community in general, nutrition is not that big of a deal.
I cannot remember much of anything about my doctors before I left college, and for a few years I didn't have a regular doctor. My memory of specific doctors starts when I was 30, and went to a new doctor who became my regular doctor for a number of years, until he retired.
All my doctors, from the one mentioned above right up to the present, stressed the importance of healthy eating (i.e. nutrition) and regular exercise. The mainstream sources I go to for health advice (Mayo Clinic, AMA, AHA, my health insurance company, and my nurse friend) all stress the importance of healthy eating and exercise for good health. All of them regard drugs as a last resort when lifestyle (especially healthy eating and exercise) fail to accomplish the goal of good health.
I have no idea where you get the idea that... for the medical community in general, nutrition is not that big of a deal.
Nutrition is not taught in medical schools; there is no recognized specialty for nutrition;

Anyone who has actually been to medical school care to comment? I find this hard to believe.
I recall :steve: saying multiple times that it forms a part of medical training in the US and that the claim that it doesnt is bunk.
My MD friends in Ireland have said the same.
There we have it. Nutrition IS a part of medical training, at least in the United States, Australia, and Ireland.
Most US medical schools (86/121, 71%) fail to provide the recommended minimum 25 hours of nutrition education; 43 (36%) provide less than half that much. Nutrition instruction is still largely confined to preclinical courses, with an average of 14.3 hours occurring in this context. Less than half of all schools report teaching any nutrition in clinical practice; practice accounts for an average of only 4.7 hours overall. Seven of the 8 schools reporting at least 40 hours of nutrition instruction provided integrated courses together with clinical practice sessions. Conclusions. Many US medical schools still fail to prepare future physicians for everyday nutrition challenges in clinical practice. It cannot be a realistic expectation for physicians to effectively address obesity, diabetes, metabolic syndrome, hospital malnutrition, and many other conditions as long as they are not taught during medical school and residency training how to recognize and treat the nutritional root causes.
Medical students are still getting less than 20 hours of nutrition education over 4 years, and even most of that has limited clinical relevance. Thirty years ago, only 37 percent of medical schools had a single course in nutrition. According to the most recent national survey, that number has since dropped to 27 percent. And, it gets even worse after students graduate.
Despite the connection between poor diet and many preventable diseases, only about one-fifth of American medical schools require students to take a nutrition course, according to David Eisenberg, adjunct associate professor of nutrition at Harvard T.H. Chan School of Public Health.
With the move to a more integrated curriculum and problem-based learning at many medical schools, a substantial portion of the total nutrition instruction is occurring outside courses specifically dedicated to nutrition. The amount of nutrition education in medical schools remains inadequate.
Dr. David Eisenberg, director of culinary nutrition at the Harvard T.H. Chan School of Public Health, applauded the AHA report, saying it documents “the total lack of requirement” in most medical schools to understand the practical skills necessary to advise patients struggling with their weight, blood sugar, blood pressure or heart disease.
Patients expect physicians to be sources of information related to nutrition. In fact, 61% of respondents to an American Dietetic Association (now the Academy of Nutrition and Dietetics) survey stated that they believe physicians are a “very credible” source of nutrition information.2 At the same time, though, in a study of internal medicine interns, 86% of respondents admitted to being inadequately trained to provide nutritional counseling. This inadequacy starts early in a physician’s career, with 51.1% of medical school graduates in 2005 reporting that they received insufficient nutrition education during medical school.3
Experts say that while most physicians may recognize that diet is influential in health, they don’t learn enough about nutrition in medical school or the training programs that follow.
And yet, medical schools have not yet woken up to the need for robust nutrition training in the curriculum. Go to see your GP and there's a fair chance that they simply won't know enough about nutrition and how to prescribe lifestyle change – even after five years of schooling in medicine.
In fact, many practicing doctors don't consider nutrition to be a conversation that they should tackle with their patients – perhaps due to their lack of fundamental grounding in the subject.
Nutrition education in medical school is rudimentary, at best, and limited for the duration of graduate medical education for many specialties. Requirements for meaningful nutrition education in all phases of medical training are long overdue.
Though students (med students) considered nutrition care as an important role for doctors they felt incapacitated by non-prioritisation of nutrition education, lack of faculty for teaching of nutrition education, poor application of nutrition science and poor collaboration with nutrition professionals. Incorporation of nutrition as a theme in medical education, improving collaboration, advocacy and creating enabling environments for nutrition education could address some of the barriers to nutrition education.
For the past 100 years, the standard medical school curriculum has required spending only a few days in four years discussing how nutrition affects wellness and the risk of progression of disease.
Yet, most physicians do not feel comfortable discussing nutrition with their patients, and most medical students readily admit that they do not get enough training in nutrition during medical school. And studies confirm this, indicating that most U.S. medical schools and teaching hospitals lack adequate nutrition-related training. Medical students spend many hours memorizing the intricacies of cellular metabolism, but very little emphasis is placed on the practical application of assessing and managing the nutritional problems of patients.
The history of nutrition in medical education has been described and reviewed in numerous publications since 1930 and extensively throughout the 1980s and 1990s.2 Research studies have shown deficiencies in nutrition education in medical schools and residency programs for more than 30 years.2, 3, 4 In 1982 and 1995, Weinsier5, 6 published consensus statements from medical nutrition educators who prioritized nutrition content and stressed its importance in the medical school curriculum. Professional organizations, medical nutrition experts, and student groups have published reports, articles, book chapters, user’s guides, and a congressional mandate urging medical schools to reform curriculum to spend more time integrating nutrition.7, 8, 9
Despite evidence that nutrition interventions reduce morbidity and mortality, malnutrition, including obesity, remains highly prevalent in hospitals and plays a major role in nearly every major chronic disease that afflicts patients. Physicians recognize that they lack the education and training in medical nutrition needed to counsel their patients and to ensure continuity of nutrition care in collaboration with other health care professionals. Nutrition education and training in specialty and subspecialty areas are inadequate, physician nutrition specialists are not recognized by the American Board of Medical Specialties, and nutrition care coverage by third payers remains woefully limited. This article focuses on residency and fellowship education and training in the United States and provides recommendations for improving medical nutrition education and practice.

Yep, a big wall of links from CarbShark purporting to "prove" that doctors receive virtually no training in an area that actual doctors are saying they do receive training in.

Well, I wouldn’t rely on your ‘understanding,’ because your understanding isn’t much. I noted that my medical training in the ‘70s in Australia included a lot of nutrition. I can’t say what the current situation is. The medical curriculum changes over time. When I retired 10 years ago, formal anatomy and histology teaching had been downgraded, so that if a medical graduate wanted to become a surgeon or a pathologist, he or she had to learn it later.
A lot of medical practice is learned from textbooks rather than from formal lectures or tutorials. Medical textbooks always contain large chapters on diet and nutrition, which are expected reading, because diet and nutrition impacts in numerous conditions. And tutors often mention diet and nutrition incidentally. I remember a general surgeon showing my tutorial group a slide of an Indonesian boy with an apparent foreign body on his lower lid. At a glance, it was an obvious case of prolapse of the lens of the eye, a sign of severe vitamin A deficiency, and an important cause of blindness.
CarbShark has the misconception that if doctors aren’t formally trained in something at university, then they’ll never learn it. But doctors are expected to undertake continuing medical education, to keep up to date with advances in their field of practice, and to acquire knowledge useful in their interests in their field of practice.
CarbShark’s ‘experts’ in the ‘alternate’ nutritional science have done exactly the same thing. Undertaken a form of continuing medical education, but one that has become derailed, going into pseudoscience and special pleading. Doctors sometimes get derailed, propounding nonsense - including naturopathy. And ‘magic’ diets.

No. Never claimed to be. That’s why I cite numerous sources. Not to glaze your eyes over but to support my arguments with objective information.
You should try it sometime
I’m not an authority on medical training. I’m just relating my experiences as a medical student at university, and my experiences as a doctor in practice with the almost mandatory continuing medical education.
Formal teaching isn’t everything in medical education. There isn’t enough time to cover everything with formal instruction in lectures. It’s just the base for informal teaching and learning. I remember as a clinical student being sent in to take a short history from a just admitted patient, and the surgical registrar gave me just a few minutes before coming in and asking for my opinion. I answered that I thought it sounded as though the patient had pyloric stenosis (which in an adult isn’t good - it suggests a cancer in the pyloric canal). The registrar asked what physical examination I’d use to confirm the diagnosis, and after a little thought (I hadn’t been formally taught it before), answered I’d shake the patient from side to side (I’d read it in a book). And to my surprise, it worked - there was an obvious ‘sloshing’ sound as the stomach contents went from side to side. And the registrar smiled...
I’m not advancing an argument. I’m just saying that there’s little difference between diets that consist of 70% carbohydrates or 70% fat, or anything in between, provided they supply sufficient but not excessive calories, adequate vitamins, minerals, essential amino acids and fatty acids, and adequate but not excessive protein.
Another anecdote. On my first day as a preclinical student at university two lecturers separately noted that around 50% of what we were going to be taught in the subsequent 6 years (all accepted and peer reviewed knowledge), would actually turn out to be false. And that no one was capable of knowing in advance which 50% that would be.
I’m not a peer review fetishist like you. Peer reviewed articles are often wrong.
Go ahead. Do the same search find the same mix of peer review; mainstream; science publications; expert interviews that disagree.
Unlike you, I am aware that I am not qualified to assess the quality of published research. I rely on trusted experts. If my pipes leak, I call a plumber.
If I have a question about the stars I ask an astronomer.
And if I feel sick (and yearly, regardless) I see a doctor. And in each case, I take their advice because they have put in years of study to understand the subtleties.
It is the height of arrogance to think that you are better equipped to understand the scientific literature on diet better than people who've spent years at university and post-graduate level learning about the human body.
Even if those people had not received one hour of training in nutrition in school, they are still a thousand times more capable of reading and understanding the literature than either you or I are.
...You have this idea that there is a monolith consensus on the diet heart hypothesis among nutrition experts, as their is with global warming, but that’s false.
For the most part most doctors haven’t learned and don’t understand the subtleties of nutrition.

Effectively, that is exactly what you are claiming when you assert that your cited articles prove your hypothesis. The implication is that doctors have failed to understand the literature, but that you do.

First I have never said prove. These studies support the hypothesis.
Second, no, most mainstream doctors don’t read every single LCHF diet study and review the way I do.

I know how you've linked sources. I can give you hundreds of signed affidavits attesting to the fact that Trump is the best President EVER, and yet we know it's not true. Your sources are crap and they don't say what you think they say.
Also, I'm absolutely certain you just strawmanned Daniel's claim. I don't believe that he said that they were 'authorities' on nutrition, but that they were TRAINED on nutrition when you claimed they knew NOTHING about nutrition. Please don't do that, it's a disingenuous way to argue.

I'm not sure if your comment about Trump is a red herring or a non-sequitur but the fact remains that I have linked to a variety of quality sources, from mainstream media, essays by experts and peer reviewed articles in reputable journals.
If you have any specific quibbles with any of them, let's here them.
Otherwise your denial of science and good sources is just as bad as Bachfiends.Quote

That's no straw man. Daniel is making an argument from authority. I am just pointing that out.
And what's with this "I don't believe he said..." are you too lazy to look one page back? It's very easy.
Hint: Daniel didn't say that. He didn't even use the word trained.
Another hint: I never said they knew nothing (all caps or not) about nutrition. I did say most know very little about diet and nutrition, had little training, and most don't care that much about it. But yes they will say things like eat a healthy diet and hand you a pamphlet or refer you to a dietician or a psychiatrist.
Well, your sources say one thing, that your low carbohydrate/high fat ketogenic diet, is reasonable in the short term (months to a year or so), and you extrapolate them to the long term, many years or decades, declaring them to be best in preventing the development of chronic diseases such as type 2 diabetes, and now cancer.

Try to keep up. We're discussing the links to articles indicating the doctors and medical professionals get inadequate training in diet and nutrition.
This is not the time for your repetition of that same crap. (actually there's never a good time for that, but it's not even on topic at this point.
OK, I stand corrected. But I made the point that based on my experience of medical training, formal teaching in lectures or tutorials doesn’t cover everything doctors are required to know. A very large part of medical education is done informally, incidentally almost like an apprenticeship. All the medical textbooks include long chapters on diet and nutrition, which are required reading.
Doctors in training don’t get examined only on topics they’re exposed to in lectures and tutorials. I remember from my preclinical training, the lecturer in anatomy didn’t manage to get below the knees, owing to running out of time at the end of the year, but the final examination for anatomy that year included questions on the anatomy of the foot. We were expected to learn foot anatomy for ourselves.
I don’t feel that the teaching of diet and nutrition at university was inadequate. And I’ve made the point that all doctors are required to undertake continuing medical education to keep up to date. If anything, I feel my training in dental medicine was grossly inadequate. There was just one lecture, and i was sick that day.

It's good to know how you feel. Of course that doesn't refute the multiple articles I linked to that contradict your feelings.
It's too bad they didn't survey the doctors about their feelings about their training in diet and nutrition, because they very well may not feel it was inadequate, even though by every objective measure it is inadequate for most doctors at most medical schools.

But doctors in practice aren’t using the stuff they were exposed to in formal lectures and tutorials at university. They’re using the stuff they learnt informally, and stuff that was reinforced by experience during practice, and as a result of continuing education.
It’s not called ‘medical practice’ for nothing. If your doctor is using only the stuff formally taught at medical school, then he or she needs to be struck off the medical registry as quickly as possible.

Thank you. You make my point in the same breath as you deny it. Bachfiend is a trained medical doctor and you claim to know more than he does about medicine and you regard him as nothing but a modern day bloodletter.
And though you don't make direct reference to my doctors, you have said that you know more about medicine than they do,
and that you understand the literature better than they do, since they directly contradict your assertions, and give essentially the same advice that bachfiend does.
And you base this entire notion on the unfounded assertion that medical doctors do not care about nutrition and that they carefully avoid reading the literature on nutrition, or that if they do read it they cannot understand it (though you think you do) or that they reject it for unstated reasons which could only be a desire to keep their patients ignorant of an easy path to health.
But I have never had a doctor who didn't care about nutrition, or who regarded it as unimportant, or who didn't urge me to eat a healthy diet.
So all that remains of your thesis is the claim that you are better able to understand published research papers than my doctors are. A claim I reject.
Though in charity to you I will grant that your Google searches might just be giving you the small minority of papers that Google thinks you want, or that get the most hits, since fringe enthusiasts will necessarily raise the search score of those papers.
Now you’re slandering me, and impugning my medical practice.

I based those comments not on his alleged resume but on what he has said.
He also continually disparages peer review scientific studies which were the one thing that lifted us out of the world of blood letters.QuoteAnd though you don't make direct reference to my doctors, you have said that you know more about medicine than they do,
Bullshit. I have absolutely never said that about your doctor or any doctor.Quoteand that you understand the literature better than they do, since they directly contradict your assertions, and give essentially the same advice that bachfiend does.
Nor have I ever said that. Those are erroneous conclusions that you draw based on false assumptions.
I noticed you haven’t answered or even acknowledge my question about a lack of consensus among doctors and nutrition experts.

More bullshit. The alternate hypothesis is based on numerous studies and analysis by experts in the various fields.
This entire tangent is based on you asking why the mainstream hasn’t embraced the alternate theory. I offered some suggestions and you extrapolated that beyond all recognition.QuoteBut I have never had a doctor who didn't care about nutrition, or who regarded it as unimportant, or who didn't urge me to eat a healthy diet.

I’ve never made that claim. That’s entirely your conjecture.

First, I never use google to search for studies in peer review journals. Even google scholar is less reliable and not as complete as pubmed.
Second you have no basis to claim that I am only looking at a minority of papers.
By far, the bulk of RCT studies comparing diet and nutrition find LCHF diets to be the most effective and healthiest weight loss diets for most people.
Further, by a wide margin the bulk of studies that look at the effects a diet high in sugar and fast simple carbs (highly processed) support the alt theory.
Go ahead and look for yourself. Prove me wrong. Just drop this entire argument from ignorance / appeal to authority. It’s unbecoming a skeptic.

You have to read the conversation from then on to realise the stupidity of CarbShark’s understanding of diet and nutrition. He claimed that the glycaemic index of steak is high (it isn’t), changed it to the insulin index (again it isn’t):

Beef steak rates very highly for ‘area under the curve for insulin’/‘area under the curve for glucose’ [basically insulin index/a glycaemic index (not the glycaemic index)] in figure 4. Beef steak elicits a much higher insulin response than it increases blood sugar.
Evidence that the dietary guidelines allow a person to have all their meals at MacDonalds?
A small aside, the new doco, "Fat a Documentary" has a bit to say on the therapeutic use of ketogenic diets for medical issues other than cancer; diabetes and epilepsy in particular.
Well, the evidence that ketogenic diets are any good for any specific type of cancer is non-existent.
Well, the evidence that ketogenic diets are any good for any specific type of cancer is non-existent.
That's not correct.
There is evidence that ketogenic diets are good for several specific types of cancer. The evidence is preliminary and not strong, but to say it's non-existent is wrong.
I refer you to the links in the OP.Well, the evidence that ketogenic diets are any good for any specific type of cancer is non-existent.
That's not correct.

Which ‘several specific types of cancers?’ And what is the nature of the evidence? Anecdotes? Case reports? Well designed clinical trials, with patients matched for stage on ketogenic or standard diet arms?
You haven’t responded to my comment that your (re)search (on the Internet) for information on diet and nutrient is very substandard, despite your claiming that your knowledge is better than mine, despite my 6 years of medical training at university and decades of clinical practice.
You still deny that you wrote that excess protein intake is shown by an increase in blood sugar?

Because it’s not worthy of a response.QuoteYou still deny that you wrote that excess protein intake is shown by an increase in blood sugar?
Never denied that. It was your inaccurate and incomplete description of what I said that I disputed.

So your evidence for the efficacy of ketogenic diets with specific cancers doesn’t even get to the level of anecdotes? Just animal models, in vitro studies of cancer cells and studies showing that cancer patients can tolerate ketogenic diets? Any studies showing that survival of cancer patients is increased on ketogenic diets?
How was my description of what you claimed about excessive protein intake inaccurate or incomplete? For a start, you were confused about glycaemic score and insulin score, and still managed to get the insulin score of steak wrong, despite correcting yourself.

Read all the linked articles.
Again you you said the evidence was not existent. There is evidence. It exists. It’s preliminary and we need more evidence.QuoteHow was my description of what you claimed about excessive protein intake inaccurate or incomplete?

I immediately corrected my error on those two indexes.
I never claimed that I could tell if someone was eating excess protein by BG levels. That Is a mischaracterization.
If you’re on a LCHF diet and your blood sugar rises inexplicably excess protein may be the cause, but there could also be other causes. Carb consumption; release of glycogen; the dawn effect.

You’re asking me to correct things where I was correct. Or the thing I’ve already corrected.
It seems that all you want to talk about is me. Get a life.
