Aggressive tumors typically demonstrate a high glycolytic rate, which results in resistance to radiation therapy and cancer progression via several molecular and physiologic mechanisms. Intriguingly, many of these mechanisms utilize the same molecular pathways that are altered through calorie and/or carbohydrate restriction. Furthermore, poorer prognosis in cancer patients who display a glycolytic phenotype characterized by metabolic alterations, such as obesity and diabetes, is now well established, providing another link between metabolic pathways and cancer progression. We review the possible roles for calorie restriction (CR) and very low carbohydrate ketogenic diets (KDs) in modulating the five R’s of radiotherapy to improve the therapeutic window between tumor control and normal tissue complication probability. Important mechanisms we discuss include (1) improved DNA repair in normal, but not tumor cells; (2) inhibition of tumor cell repopulation through modulation of the PI3K–Akt–mTORC1 pathway downstream of insulin and IGF1; (3) redistribution of normal cells into more radioresistant phases of the cell cycle; (4) normalization of the tumor vasculature by targeting hypoxia-inducible factor-1α downstream of the PI3K–Akt–mTOR pathway; (5) increasing the intrinsic radioresistance of normal cells through ketone bodies but decreasing that of tumor cells by targeting glycolysis. These mechanisms are discussed in the framework of animal and human studies, taking into account the commonalities and differences between CR and KDs. We conclude that CR and KDs may act synergistically with radiation therapy for the treatment of cancer patients and provide some guidelines for implementing these dietary interventions into clinical practice.
Some would argue, however, that these cut-off points are arbitrary and do not apply to all individuals depending on their baseline metabolic health and overall health. For instance, far too many examples exist of people with low LDL levels having heart attacks and those with high LDL having improved longevity. So while these numbers make sense for whole populations, tremendous individual variation exists.
Another difference between older and newer studies is that the type of patients treated with the ketogenic diet has changed over time. When first developed and used, the ketogenic diet was not a treatment of last resort; in contrast, the children in modern studies have already tried and failed a number of anticonvulsant drugs, so may be assumed to have more difficult-to-treat epilepsy. Early and modern studies also differ because the treatment protocol has changed. In older protocols, the diet was initiated with a prolonged fast, designed to lose 5–10% body weight, and heavily restricted the calorie intake. Concerns over child health and growth led to a relaxation of the diet's restrictions.[19] Fluid restriction was once a feature of the diet, but this led to increased risk of constipation and kidney stones, and is no longer considered beneficial.[18]
Dieter beware: U.S. News & World Report, in its high-profile January cover story on "best diets," calls the DASH and Mediterranean diets tops for health, though these regimens represent the failed nutritional status quo of the last 50 years. It's clear that U.S. News — which employed an expert panel to rate 40 diets on various criteria — merely recapitulated questionable dietary advice that has gone by a succession of names since the 1970s — "low-fat," "DASH," "USDA-style," "plant-based." The basic set of recommendations have remained the same, emphasizing plant foods (grains, cereals, fruits and vegetables) over animal products (eggs, regular dairy, meat), and vegetable oils over natural animal fats such as butter. According to government data, Americans have largely followed these recommendations over the last 50 years, notably increasing their consumption of grains, vegetables and fruits and eating less whole milk, butter, meat and eggs. The outcome? In that time, rates of obesity and Type 2 diabetes have skyrocketed. Something has gone terribly wrong. Why would 25 doctors, dietitians and nutritionists on the U.S. News panel choose a dietary philosophy that has — so far, at least — failed us?
The conventional view of cancer is that it is caused by DNA mutations in the cell nuclei. However, the metabolic theory of cancer proposes that some cancers are caused by a dysfunction of cellular respiration and that the restriction of glucose in the diet may prevent and even reverse some cancers. Today I’ll review the research supporting this theory and explore how the ketogenic diet may impact cancer tumor growth.
Fasting continues until dinner on day 1 of the admission. At this time, half of the calculated diet is provided as an ‘eggnog’ (or ketogenic formula). A ketogenic eggnog looks and tastes like a milkshake and can be sipped, frozen as ice cream, or cooked as scrambled eggs. Excess ketosis at this time, which may cause vomiting, can be relieved with a small amount of orange juice. Once the child begins eating, serum glucose checks are unnecessary and are discontinued.
Note: Are you a vegetarian or vegan and want to go on a ketogenic diet? It’s still possible! Just keep in mind that the dietary restrictions can sometimes be a little bit intense. Make sure to plan ahead and prepare to aid your success. To help out, we’ve published articles (with 7 day meal plans included) for both the vegetarian ketogenic diet and the vegan ketogenic diet.

To maximize your vitamin D levels, it is best to get in the sun as much as possible, but not so much that you burn your skin. Ideally, you want to have 40% or more of your skin exposed to the sun for at least 15 minutes per day in the early afternoon. If you can’t get that much sun exposure every day, then supplementing with around 4,000 IU of vitamin D3 daily may be your next best option.

Jimmy Moore: One year ago my, I guess this about a year and a half ago now, time flies when you’re having fun … my total cholesterol was over 400. A lot of people, and of course I talked to lipidologists and heart people all the time on my podcasts, and I was throwing the numbers out there and one of the lipidologists “Oh you need the highest dose of Staten drug possible because you’ll not be able to get that down without it.” In writing Cholesterol Clarity, I determined that I had some other things that were raising the cholesterol and it’s not that I have a Staten drug deficiency. It’s that I have something underlined inside of me somewhere that the cholesterol was going to try to take care of.

Cancer – One exciting frontier for the potential use of a ketogenic diet is as an adjunct treatment for certain types of cancers. In 1924 Otto Warburg first published his observation that, unlike healthy cells, nearly all cancer cells fuel themselves through glycolysis, a means of creating energy through the fermentation of glucose. What we now call the “Warburg Effect” has led many researchers to theorize that if cancer cells are starved of glucose, they will stop spreading, while healthy cells will continue to thrive on the alternative fuel source of ketones. In mice, a ketogenic diet is known to inhibit certain pathways and lower certain compounds involved in tumor formation.35 Research thus far is very preliminary, but because a ketogenic diet appears to target major energy pathways responsible for tumor growth and survival, it may enhance the efficacy of conventional treatments and even reduce side effects in some types of cancers. 36 37 38
"Findings from our study reveal that treating mice chronically with specific bacteria that were enriched by the ketogenic diet protected them from seizures," study senior author Elaine Hsiao, an assistant professor of integrative biology and physiology at the University of California, Los Angeles (UCLA), told Live Science. ("Keto diet" is short for "ketogenic diet.") However, Hsiao stressed that more studies are needed before researchers know if the findings also apply to people.
In their conclusions, they stated that the favorable response could be attributed “in part” to the calorie-restricted ketogenic diet. However, the researchers emphasized that “further studies are needed to evaluate the efficacy of restricted ketogenic diets, administered alone or together with standard treatment, as a therapy for GBM and possibly other malignant brain tumors.”

Children who discontinue the diet after achieving seizure freedom have about a 20% risk of seizures returning. The length of time until recurrence is highly variable, but averages two years. This risk of recurrence compares with 10% for resective surgery (where part of the brain is removed) and 30–50% for anticonvulsant therapy. Of those who have a recurrence, just over half can regain freedom from seizures either with anticonvulsants or by returning to the ketogenic diet. Recurrence is more likely if, despite seizure freedom, an electroencephalogram shows epileptiform spikes, which indicate epileptic activity in the brain but are below the level that will cause a seizure. Recurrence is also likely if an MRI scan shows focal abnormalities (for example, as in children with tuberous sclerosis). Such children may remain on the diet longer than average, and children with tuberous sclerosis who achieve seizure freedom could remain on the ketogenic diet indefinitely.[46]

A short-lived increase in seizure frequency may occur during illness or if ketone levels fluctuate. The diet may be modified if seizure frequency remains high, or the child is losing weight.[19] Loss of seizure-control may come from unexpected sources. Even "sugar-free" food can contain carbohydrates such as maltodextrin, sorbitol, starch, and fructose. The sorbitol content of suntan lotion and other skincare products may be high enough for some to be absorbed through the skin and thus negate ketosis.[31]

Well, I am going to give this another try. I have great difficulty in eating greens , or drinking them, also I am not fond of fats, years and years of low fat diets have totally screwed my metabolism,and taste buds. I will read this page every day to keep my mind focused. Start tomorrow when I get up …… I work nights which can cause me problems as well. When I tried this diet before, I got terrible cramp, now I realise I wasn’t drinking enough water. goes.

Typically known as the “bad cholesterol” to its healthy counterpart HDL cholesterol, increased levels of LDL cholesterol are associated with an increased risk of cardiovascular diseases (CVD). [14] Some studies show a strong correlation between LDL cholesterol and the risk of cardiovascular diseases in both men and women. [15] Evidence also suggests that decreasing blood levels of LDL-C reduces the risk of CVD. [16]

You’re transitioning. Your body is equipped to process a high intake of carbs and a lower intake of fat. Your body needs to create enzymes to be able to do this. In the transitional period, the brain may run low on energy which can lead to grogginess, nausea, and headaches. If you’re having a large problem with this, you can choose to reduce carb intake gradually.
Let’s go back to the research assessing how the low-carb, high-fat diets such as the ketogenic diet affect your LDL levels. In the meta-analysis by Bueno et al., low-carb diets were shown to increase HDL twice as much as low-fat diets after randomized controlled interventions. It also showed that there was a small increase in LDL-C in low-carb subjects compared to low-fat diet subjects who experienced no increase.

Notice he used the word “effective” twice. The word “effective” does not mean cure. It typically only means temporarily slowed growth or temporary tumor shrinkage. To put it in perspective, over 580,000 “effectively treated” cancer patients die in the U.S. each year. The sobering truth is the cancer industry has only improved the overall cancer death rate by 5% in the last 60+ years. “Ineffectively treated” is a more accurate and appropriate way to describe the current state of affairs, but I digress.

Proponents of the super-high-fat, low-protein approach argue that protein kicks the body out of ketosis by supplying amino acids for gluconeogenesis (simply put, turning non-carbs into fuel); however, research indicates that the impact of dietary protein on gluconeogenesis and glucose flux is nearly negligible, making this argument irrelevant. (42) In my practice, we have found that usual protein intakes (15 to 20 percent of calories) do not have appreciable effects on blood ketone levels. Besides, a super-high-fat, low-protein diet typically has more drawbacks than benefits—it may cause weight gain, muscle loss, fatigue, and chronic hunger. Don’t be afraid of including plenty of protein in your ketogenic diet; protein is a powerful tool that will satiate your appetite while facilitating fat loss and preventing muscle loss.
Tapping into consumers’ desire to glean the benefits of ketosis right this minute—or in the next 30 minutes—manufacturers have created powders and other supplements that promise you can enjoy your favorite foods and still get into ketosis. These supplements—called exogenous ketones—aren’t necessarily bad, but neither are they a free pass to indulge and then effortlessly shift into ketosis.
All of this talk about energy metabolism leads us to another important finding in the cancer literature: healthy cells can also become cancerous if their mitochondria (the primary energy producer of the cell) is dysfunctional for an extended period of time. Furthermore, if the cell is already cancerous, the mitochondrial dysfunction will make the cell’s genes vulnerable to additional mutations.
There have been a few studies of the modified Atkins Diet in adults with seizure disorders, and the results are similar to studies with children. Interestingly, it was remarked in one of the reports that it was more difficult to keep adults on the diet since they obviously have more control over what they eat. Research is still limited in this area and more trials are needed.

Tony, I'm not sure how you were only eating 20 grams of fat on a keto diet; in fact, if this is true, that may be the reason. A keto diet should provide a minimum of 70 grams of fat daily, but generally 100+ grams for most people, especially men. Be sure to include nuts, olive oil, avocados, fatty fish, and other healthy sources of fat in your diet on a daily basis in order to prevent problems. - Franziska
Ketone production is the body’s natural response to very low or no carbohydrate availability. The ketogenic diet was developed to mimic the effects of fasting while still supplying adequate nutrition to maintain health. The classic ketogenic diet, developed in the early 1900s for children with epilepsy, consisted of a 3 or 4:1 ratio of fats to protein and carbohydrates combined, supplying up to 90% of the daily calories from fats.44 More recently, modified versions have emerged with similar rates of efficacy, and the wider variety of food and flexibility make the diet less arduous. Two such possible modifications are: a 1:1 and 2:1 ratios of fats to combined protein and carbohydrates and/or the addition of medium chain triglyceride (MCT) oil supplements. The medium chain fats that makeup MCTs more readily produce ketones than the long chain fats commonly found in the diet, allowing for a lower amount of total fat intake, and therefore increasing the amount of carbohydrate and protein that can be included in the diet.45

In order to transition and remain in this state, aiming for about 30–50 net grams is typically the recommended amount of total carbs to start with. This is considered a more moderate or flexible approach but can be less overwhelming to begin with. Once you’re more accustomed to “eating keto,” you can choose to lower carbs even more if you’d like (perhaps only from time to time), down to about 20 grams of net carbs daily. This is considered the standard, “strict” amount that many keto dieters aim to adhere to for best results, but remember that everyone is a bit different.
One of the difficult things about science-based medicine is determining what is and isn’t quackery. While it is quite obvious that modalities such as homeopathy, acupuncture, reflexology, craniosacral therapy, Hulda Clark’s “zapper,” the Gerson therapy and Gonzalez protocol for cancer, and reiki (not to mention every other “energy healing” therapy) are the rankest quackery, there are lots of treatments that are harder to classify. Much of the time, these treatments that seemingly fall into a “gray area” are treatments that have shown promise in animals but have never been tested rigorously in humans or are based on scientific principles that sound reasonable but, again, have never been tested rigorously in humans. (Are you sensing a pattern here yet?) Often these therapies are promoted by true believers whose enthusiasm greatly outstrips the evidence base for their preferred treatment. Lately, I’ve been seeing just such a therapy being promoted around the usual social media sources, such as Facebook, Twitter, and the like. I’ve been meaning to write about it for a bit, but, as is so often the case with my Dug the Dog nature—squirrel!—other topics caught my attention.
One of the truly exciting new frontiers in nutrition therapy is the study of the high-fat low-carb ketogenic diet, especially in relation to preventing and curing cancer. The ketogenic diet as a therapeutic diet is not new. It has been around at least since the 1920s, when researchers at Johns Hopkins discovered that the diet could cure some children from epileptic seizures where drugs had failed.
Notice he used the word “effective” twice. The word “effective” does not mean cure. It typically only means temporarily slowed growth or temporary tumor shrinkage. To put it in perspective, over 580,000 “effectively treated” cancer patients die in the U.S. each year.

In my opinion, Bob Atkins knew more about the theory and practice of the ketogenic diet, its benefits and limitations, including as applied to cancer patients, than anyone in the history of medicine. For him, the concept was hardly the musings of a PhD laboratory scientist, but the practical observations of a physician who treated thousands of patients over decades. And for cancer, the ketogenic diet just did not seem to work.
One way to tell if the keto diet may not be ideal for you is if your total-to-HDL cholesterol ratio is above 4 and/or your LDL-P remain high or increase after starting the keto diet. If this is the case for you, then it may indicate that you have a particular condition that requires you to make adjustments to your keto diet or follow a completely different diet altogehter. [27]
In one hypoxia-ischemia model, rats fed a ketogenic diet for 25 days before cardiac arrest had fewer postarrest seizures and myoclonic jerks and less neurodegeneration (determined by Fluoro-Jade staining) than those fed a normal diet [28,29]. The ketogenic diet also appears to have cardioprotective properties in an isolated heart perfusion model designed to mimic global ischemia. These changes were concomitant with increased numbers of mitochondria in cardiac muscle, suggesting that improved capacity to generate energy conferred a protective effect in the face of an ischemic insult [30].
Bulk buy and cook. If you’re someone who doesn’t like to spend a lot of time in the kitchen, this is the best of both worlds. Buying your food at bulk (specifically from wholesalers) can reduce the cost per pound tremendously. Plus, you can make ahead food (bulk cook chicken thighs for pre-made meat, or cook entire meals) that are used as leftovers, so you spend less time cooking.

Thank you, Thank you, Thank you!!!!! Your article couldn't have been timed any better. I got my blood panel back from my "western" doctor two days ago and the numbers had me very worried. After reading your post yesterday I felt so much better and sent the results off to my naturopath knowing that everything should be fine. I printed it out for my own reference and for any others, doctors included, who may have doubts and questions. Again, a big thanks for all your research and putting it out there for the rest of us trying to live a longer, healthier life!!

The use of the LGIT in the treatment of drug-resistant epilepsy was initially reported in 2005 by Pfeifer and Thiele (2005). This alternative diet treatment is based on a ratio 0.6:1 of fat to carbohydrates and protein, containing 60% fats, 30% protein, and 10% carbohydrates with a low glycemic index (GI) (GI<50) (Pfeifer and Thiele, 2005; Payne et al., 2018). The GI measures the tendency of a food to raise the blood glucose levels, compared to an equivalent amount of the reference carbohydrate, usually glucose (Pfeifer et al., 2008). Compared to classic the KD, the LGIT produces a smaller increase in ketone body levels, but has comparable efficacy, better tolerability and easier implementation (Pfeifer and Thiele, 2005; Pfeifer et al., 2008).
You will need to learn how to prepare meals differently, which takes time and work. There also may be some difficulty adapting to the new meals. However, with creative meal planning and sensitivity to your difficulties, along with support from your ketogenic diet team some of these obstacles can be overcome. In time you will adapt with the significant changes and meal preparation and meal time will become easier. Many families cope well with the challenges and would agree that the hard work is worth it if the diet significantly reduces the seizures.

"Most of the work in this field is still pre-clinical, meaning it's been conducted in animal models," Angela Poff, a research associate in the Department of Molecular Pharmacology and Physiology at the University of South Florida, told U.S. News & World Report. "It's been done in various cancer types, but most of the work has been done in brain cancer specifically. But there's very little clinical data all around. There's some case reports and very small preliminary clinical studies in small groups of patients, usually very late-stage patients with various types of cancers. So in the clinical realm, which is the most important in telling us whether this is going to be useful, we have a long way to go."

She learned about Kelley’s work, began the program, regained her health, and avoided all conventional doctors for many years. In 1984, nine years after coming under Kelley’s care, she returned to her primary care physician who was quite perplexed she was still alive after all this time. A chest x-ray showed total resolution of her once widespread lung metastases. 

It is possible to combine the results of several small studies to produce evidence that is stronger than that available from each study alone—a statistical method known as meta-analysis. One of four such analyses, conducted in 2006, looked at 19 studies on a total of 1,084 patients.[23] It concluded that a third achieved an excellent reduction in seizure frequency and half the patients achieved a good reduction.[18]
Some experts now feel that impaired energy metabolism may be the defining common factor in nearly all cancers, regardless of their origin.12,14 They believe that cancer, rather than being caused by errors in DNA, is fundamentally a metabolic disease caused by a disruption in a cancer cell’s ability to get the energy it needs from mitochondrial respiration like a normal cell would.
Gluconeogenesis is the endogenous production of glucose in the body, especially in the liver primarily from lactic acid, glycerol, and the amino acids alanine and glutamine. When glucose availability drops further, the endogenous production of glucose is not able to keep up with the needs of the body and ketogenesis begins in order to provide an alternate source of energy in the form of ketone bodies. Ketone bodies replace glucose as a primary source of energy. During ketogenesis due to low blood glucose feedback, stimulus for insulin secretion is also low, which sharply reduces the stimulus for fat and glucose storage. Other hormonal changes may contribute to the increased breakdown of fats that result in fatty acids. Fatty acids are metabolized to acetoacetate which is later converted to beta-hydroxybutyrate and acetone. These are the basic ketone bodies that accumulate in the body as a ketogenic diet is sustained. This metabolic state is referred to as "nutritional ketosis." As long as the body is deprived of carbohydrates, metabolism remains in the ketotic state. The nutritional ketosis state is considered quite safe, as ketone bodies are produced in small concentrations without any alterations in blood pH. It greatly differs from ketoacidosis, a life-threatening condition where ketone bodies are produced in extremely larger concentrations, altering blood ph to acidotic a state.

Kidney stones have occurred in about 6 percent of patients and may be increased in younger patients (<3 years of age), and those with hypercalciuria and low urine volume. Oral potassium citrate as a preventative supplement results in urine alkalinization, decreasing the prevalence of kidney stones. Universal supplementation appears to drop the risk of stones to nearly zero.
Historically, elevated blood cholesterol levels have been linked to atherosclerosis, a condition involving deposits of plaque that cause the arterial lining to thicken and potentially impair blood flow to the heart. The process of plaque deposition is complex but involves white blood cells, calcium, cholesterol, and other substances converging at the site of inflamed or damaged arteries.
You’re very welcome, Judy! I’m glad it’s helpful. If you are keto (as opposed to low carb), unfortunately peaches would not allow you to stay in ketosis. You can check my keto food list to help determine what is keto friendly. Of course, there are worse things than fresh fruit 🙂 but in the end our bodies still see the sugar. That being said, it doesn’t mean you sabotaged the whole day. Just pick up again – you got this!! (And for next time, try some fresh berries in moderation when you’re craving fruit.)
The Ketogenic Diet (KD) is a modality of treatment used since the 1920s as a treatment for intractable epilepsy. It has been proposed as a dietary treatment that would produce similar benefits to fasting, which is already recorded in the Hippocratic collection. The KD has a high fat content (90%) and low protein and carbohydrate. Evidence shows that KD and its variants are a good alternative for non-surgical pharmacoresistant patients with epilepsy of any age, taking into account that the type of diet should be designed individually and that less-restrictive and more-palatable diets are usually better options for adults and adolescents. This review discusses the KD, including the possible mechanisms of action, applicability, side effects, and evidence for its efficacy, and for the more-palatable diets such as the Modified Atkins Diet (MAD) and the Low Glycemic Index Diet (LGID) in children and adults.
The next case report is from 2010. It describes the case of a 65-year-old woman who presented with progressive memory loss, chronic headaches, nausea, and a right hemisphere multi-centric tumor seen with magnetic resonance imaging (MRI). Following incomplete surgical resection, the patient was diagnosed with glioblastoma multiforme (GBM). Now here’s the kicker: The patient underwent standard therapy plus the ketogenic diet. A day after her surgery, she underwent a two-day fast, followed by a three day fast beginning a week after surgery, followed by a restricted ketogenic diet (only 600 Cal/day). Three weeks after her surgery (and two weeks after starting the ketogenic diet) she began standard of care treatment, concomitant radiation plus chemotherapy (temozolomide), “according to standard procedures,” which lasted six weeks. The patient also had a gene mutation in her tumor that produces increased sensitivity to temozolomide. The conclusion? Fortunately for the patient, she had what appears to have been a complete response, after which she went on a less restrictive ketogenic diet. Unfortunately, the patient recurred eight months later. By that point, the patient was off of the ketogenic diet. The authors’ conclusion? Because it was “unlikely” that the tumor would have responded this well on standard therapy alone, it must have been adding the ketogenic diet that done it. Worse, in the talk, Dr. Seyfried strongly implies that the tumor recurred because she had gone off the ketogenic diet two and a half months before her recurrence.
To some ears, last week’s exultation over interleukin-2 has a familiar but discordant ring. Something similar happened about five years ago with a substance called interferon, the “magic bullet” of cancer research, featured on magazine covers and in articles with titles like “To Save Her Life – And Yours.” … But by 1984 the magic bullet had misfired; now the articles were called “The Myth of Interferon.”
Kelsey: Hi, Chris, I was just wondering about your thoughts on the ketogenic diet as an approach to cancer prevention and therapy. I just read something about how cancer cells can only thrive on glucose, and in its absence we can prevent cancer potentially. So I was wondering if you could discuss this in a podcast. I think that would be great. Thank you.
So far the research has found energy restriction to significantly reduce growth and progression of numerous cancers including mammary, brain, colon, pancreas, lung, and prostate cancer. However, it is important to note that the best results are achieved from severe calorie restriction (<1,000 calories per day). If you are considering using calorie restriction along with your cancer treatment, make sure you consult your cancer care team first.
