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
Epilepsy is a disabling and common neurological disease, which can be controlled successfully in most patients with one or more antiepileptic drugs. Approximately 30% of patients with epilepsy have refractory epilepsy, that is, have a failure of adequate trials of two tolerated, appropriately chosen and used antiepileptic drug schedules to achieve sustained relief of seizures (Picot et al., 2008; Kwan et al., 2009). Some of these patients are not surgery candidates, so it is necessary to search for alternative treatments for epilepsy such as palliative surgery, neuromodulation, and a ketogenic diet (KD).
With all due respect Dr. Kresser, I’m not aware of any cancer is reversed under Ketogenic diet. It’s all just a bunch of pretty theory but nothing in practice. As we speak there are probably thousands of people tried and done Ketogenic diet both for “health” reason and cancer cure. And yet… no report ever surface of the success of Keto diet in reversing cancer.
Cyclical ketosis means you’re sometimes in ketosis and sometimes aren’t. A few days each week—the night before workout days to build glycogen stores in your muscles—try increasing your intake of berries, higher complex carb veggies (like sweet potatoes), and non-gluten grains. It might knock you out of ketosis temporarily, but it also provides a wealth of nutrients to keep you lean, healthy, and happy. This is also called flexible ketosis, which creates metabolic flexibility—the holy grail of metabolism management. I’ve also talked about cycling ketosis with intermittent fasting, which provides a win-win strategy to reach your health goals.
Ketone bodies, acetoacetate, and β-hydroxybutyrate (βOHB), are byproducts of fatty acid oxidation in the mitochondrial matrix of the hepatocytes. There are many theories about the role of KB, but the existence of an anticonvulsant effect is controversial. Some authors have found no relationship between KB and synaptic transmission and seizure control.
Researchers also observed that the size of VLDL particle size did not change in either of the groups. However, they noted that the total number of VLDL particles decreased by 19% from 76.2 nmol/L to 61.7 nmol/L. [22] More specifically, large VLDL particles reduced by 40.2% from 3.33 nmol/L to 1.74 nmol/L, medium VLDL particles decreased by 4.8% from 46.2 nmol/L to 44 nmol/L. [22]
firstly, the LMHR profile also applies to long-term fasting studies - this is perhaps where it can be observed in its natural, unconfounded state - LDL rises in lean healthy individuals during a fast, but drops or stays stable in those with obesity or atherosclerosis (period varies from 3-21 days). This is consistent with the keto pattern; this evidence clearly shows that LDL divergence is related to burning a high % of fat, and not to eating it, which is to some extent a confounder with keto (as shown by the cholesterol drop protocol and the possible different effects of different fat types and amounts).
A ketogenic diet could be an interesting alternative to treat certain conditions, and may accelerate weight loss. But it is hard to follow and it can be heavy on red meat and other fatty, processed, and salty foods that are notoriously unhealthy. We also do not know much about its long-term effects, probably because it’s so hard to stick with that people can’t eat this way for a long time. It is also important to remember that “yo-yo diets” that lead to rapid weight loss fluctuation are associated with increased mortality. Instead of engaging in the next popular diet that would last only a few weeks to months (for most people that includes a ketogenic diet), try to embrace change that is sustainable over the long term. A balanced, unprocessed diet, rich in very colorful fruits and vegetables, lean meats, fish, whole grains, nuts, seeds, olive oil, and lots of water seems to have the best evidence for a long, healthier, vibrant life.

Of course, we know that genes alone are not responsible for cancer because we share many of the same genes as our hunter–gatherer ancestors and even just the same genes as our ancestors several generations ago, and yet the rate of cancer keeps going up. It’s expected to overtake cardiovascular disease as the number one cause of death in the U.S. fairly soon, and so that can’t be explained by genes alone.
The MAD aims to provide increased flexibility and palatability, with a 1:1 ratio of fat to carbohydrates and protein, and contains around 65% fat, 25% protein, and 10% carbohydrate (Payne et al., 2018). Fat is encouraged and the carbohydrate intake is limited to 10–20 g/day in children and 15–20 g/day in adults (Kossoff, 2004; Kossoff and Dorward, 2008). Because of carbohydrate restriction, the MAD can also produce urinary ketones (Carrette et al., 2008). The MAD does not require weighing food on a gram scale, or restriction of calories, protein or liquids, and may be a good option for patients who are unable to tolerate a more restrictive diet such as the classical ketogenic diet (KD) (Cervenka et al., 2012). Low-carbohydrate multivitamin and calcium carbonate supplementation is recommended in the MAD (Kossoff et al., 2009).
In his talk, Dr. Seyfried begins with what he refers to as a “provocative question”: Is cancer a genetic or metabolic disease? Actually, whether he realizes it or not, his question is not quite as provocative as he thinks it is, nor is the answer anywhere near as clear-cut as he thinks it is or as he characterizes oncologists and cancer researchers as thinking it is. I’ll tell you what I think the answer to the question is after I’ve discussed Dr. Seyfried’s hypothesis. In the meantime, not surprisingly, his answer is that cancer is a metabolic disease, while everyone else’s answer—according to him, at least—is that it is a genetic disease, making him the brave maverick doctor, who says things like:
Other concerns that may arise from remaining on a ketogenic diet long term include mineral deficiencies, decreased bone mass, decreased thyroid function, thinning hair and/or hair loss, heart problems, and menstrual irregularities.59 While it is possible that some of these problems can be mitigated with appropriate supplementation (e.g. fiber, adaptogenic herbs and minerals), ensuring regular adequate caloric intake, and adjusting carbohydrate intake to meet personal needs, not all people will thrive on a ketogenic diet. It is wise to work with an experienced practitioner who can help monitor blood work and symptoms for unwanted changes if you plan to stay on a ketogenic diet long-term.

A ketogenic diet promotes healing of the brain following TBI by increasing the activity of genes genes involved in energy metabolism, stimulating the generation of new mitochondria, and inhibiting the production of damaging reactive oxygen species in the brain. (24) In animal models of TBI, a ketogenic diet reduces cerebral edema and neuronal cell death while improving behavioral outcomes. (25, 26) While individual success stories of people using a ketogenic diet for TBI are easy to find on the internet, formal clinical trials are still needed.
In other words, clinical data should be rolling in fairly soon, and that’s a good thing. In the meantime Dr. Seyfried and other advocates who so passionately believe that ketogenic diets will greatly help patients with brain cancer do no one any favors by claiming unequivocally that cancer is a metabolic disease and saying that ketogenic diets are more beneficial than chemotherapy for patients with brain tumors.

Failing to consume enough calories on a keto diet can cause fatigue and insomnia, while an insufficient protein intake promotes weight gain and muscle loss. When you first begin a keto diet, it can be helpful to track your food intake with an app such as Carb Manager Keto Diet App; this will allow you to visualize your macronutrient intake and ensure that you don’t undereat calories or protein. As I mentioned earlier, a low-protein intake is not required to obtain the benefits of keto. A sufficient protein intake (15 to 30 percent of total calories) suppresses hunger and, in most people, does not affect blood ketone levels. (43)


I want to be very clear, though, that I don’t believe claims that are made on some websites that the ketogenic diet beats chemotherapy for all cancer treatment. There’s simply no research to support that. I don’t know where those websites are getting that idea, and there’s a lot of snake oil when it comes to cancer treatment out there. It’s a really vulnerable population. Someone who’s diagnosed with cancer, particularly a late-stage cancer that might be terminal, understandably we often feel pretty desperate and might not have the capacity at that moment in time to go through the proper vetting process to make sure that some of the more alternative therapies that are suggested are legitimate, and so you see a lot of wacky stuff recommended for cancer treatment.

If you’ve decided to move forward in trying the keto diet, you will want to stick to the parameters of the eating plan. Roughly 60 to 80 percent of your calories will come from fats. That means you’ll eat meats, fats, and oils, and a very limited amount of nonstarchy vegetables, she says. (This is different from a traditional low-carb diet, as even fewer carbs are allowed on the keto diet.) 

I actually clicked on the story just to see if they included anything about it’s use in managing chronic migraine. I have chronic migraine, basically intractable. Nothing has helped. I’ve tried medications, meditations, and everything in between including a bunch of dietary changes. Keto is my next consideration. I’m happy to hear it helped you! Thanks for sharing
In subsequent years, the boy continued on aggressive conventional therapeutics, when in 2007, the parents learned of the preliminary research of Dr. Seyfried. While continuing low-dose chemotherapy combined with the ketogenic diet, the patient experienced a “15%” reduction in tumor size. The chemo was eventually discontinued while the parents maintained their son on the ketogenic diet, and the child, sadly, eventually died.
Overall, 12 studies including 1257 patients examined the impact of a VLCKD on HDL cholesterol. When assessing the data, the individuals assigned to a VLCKD achieved an average increase in HDL of 0.12 mmol/L. This was double the average increase in HDL of the low-fat dieters who achieved an average increase in HDL of 0.06 mmol/L. [11] As a result, the authors concluded that carbohydrate-restricted diets confer cardiovascular benefits because they improve levels on HDL in the body. [11]
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.
I too am a lean mass hyper responder and have FH with very high levels of LDL and HDL but have never had the tests to separate out the different types of LDL. I thought my relatively low fat diet with high fibre would be good for me and help prevent plaque build up, although I have read some excellent articles and books relating to the link between high cholesterol and heart disease being very fabricated. When I recently had a well-man check up and discovered that I was pre type II diabetic, I thought, WTF! I have been so careful for so many years not to have simple sugars in my diet and only complex carbs with plenty of fibre - and yet, there I am with my Dr telling me I'm on the verge of diabetes! So, I'm going on the side of plenty of good fats are really good for me - even with really high cholesterol levels - and am now two weeks into a Keto diet - lost a bit of weight, so boy am I skinny now - but feeling great with much more energy and clarity of thought / consciousness. My gout is subsiding, my eczema is not flaring up so much and not so itchy in other areas either! Also the keto diet feels and tastes so good - I love eating fish and meat and avocados and love to simply eat teaspoons of coconut oil. I tend to snack on nuts and seeds during the day after a morning fast so I only eat between midday and about 6-7pm in the evening. Who knows whether or not I will have a heart attack in my late fifties like my mum or a stroke at 65 like my father!

After scouring the literature, he became quite attracted to the “good science” behind the ketogenic hypothesis, so under Dr. Seyfried’s direct supervision, he began the diet. Though the patient seems quite enthusiastic about his response, he admits in his note that with the diet there has been “no progression,” presumably in terms of x-ray studies, and some improvement in the blood studies. He still considers his disease as “incurable.”
In both patients, levels of blood glucose decreased to low/normal levels and ketones increased by 20 to 30 times within seven days of starting the ketogenic diet.  Results from scans indicated that there was a 21.8% decrease in glucose uptake at the tumor sites in both subjects. Lower glucose uptake is a strong indicator that a tumor is shrinking in size.
Calorie restriction, while more difficult than intermittent fasting for some, has shown promising results in preventing and starving cancer for the same reasons as intermittent fasting. Basically, calorie restriction will cause cancer to run itself out of fuel because of its constant need for glucose and lack of metabolic flexibility. Once that happens, the cancer may begin to starve and die off.
Leanne: Yeah, that’s amazing that you took your health into your own hands. I think that’s so empowering for so many people. When we just say “enough is enough and we need to change.” For me I came at this from the hormone piece, but also we have a strong line of dementia in our family. Very, very strong. For me, it was how can I be as good to my brain as possible? Not only is this good for your heart and everything else, but also looking at the health of your brain, which we talked about with having enough cholesterol is important for our brain function, too.
One downside to a ketogenic diet for weight loss is the difficulty maintaining it. “Studies show that weight loss results from being on a low-carb diet for more than 12 months tend to be the same as being on a normal, healthy diet,” says Mattinson. While you may be eating more satiating fats (like peanut butter, regular butter, or avocado), you’re also way more limited in what’s allowed on the diet, which can make everyday situations, like eating dinner with family or going out with friends, far more difficult. Because people often find it tough to sustain, it’s easy to rely on it as a short-term diet rather than a long-term lifestyle.
Preclinical research suggests that a ketogenic diet may also benefit those with Parkinson’s disease. In animal models of Parkinson’s, a ketogenic diet improves motor function, and in humans with Parkinson’s, it improves nonmotor symptoms such as daytime sleepiness and cognitive disorders. (22, 23) While more research is needed, a ketogenic diet may be a powerful intervention well worth a try for both Alzheimer’s and Parkinson’s patients.
HDL stands for high-density lipoprotein and its primary role in the body is actually to sweep up LDL particles and return them to the liver for recycling. This is because LDL is actually very susceptible to oxidation so it must be cleared from the blood efficiently. This means when LDL is exposed to chronic inflammation, it becomes damaged. The longer LDL remains in the blood stream and the higher your inflammation levels are, the higher your risk of heart disease.
Artificial sweeteners such as saccharin (Sweet’N Low), aspartame (NutraSweet, Equal), and sucralose (Splenda) are quite popular among low-carb dieters. However, concerning new research indicates that artificial sweeteners have adverse metabolic effects and may work against your keto efforts by disrupting your gut microbiota and inducing insulin resistance and weight gain. (46, 47) If you want to use a non-caloric sweetener, I recommend either stevia or monk fruit sweetener.
But there are some cancer biologists out there that feel that while mutations are ubiquitous in cancer, they may not be the primary driving force of the disease and, as we’ll discuss later, they may actually be secondary effects of a deeper underlying process. They believe that cancer is as much a disorder of altered energy metabolism or energy production as it is genetic damage. This goes back to the work of German physician Otto Warburg in the 1920s and 1930s, and we know that healthy cells generate energy using an oxygen-based process of respiration. This is what we refer to as cellular respiration, but Warburg was the first to note that cancer cells prefer an anaerobic, or oxygen-free, process of producing cellular energy known as fermentation.
Understandably, most have become concerned, since elevated LDL is typically considered a major heart disease risk factor. However, the reason for this response - and whether it poses significant health risks – isn't completely understood or agreed upon by experts. This article takes a balanced look at the issue and its potential implications for cardiovascular disease and overall health.
Great article! I have been diagnosed with familial hypercholesterolemia, however, I am not concerned at all. I continue to follow a restricted calorie, zero carb ketogenic diet, that I have been doing strictly for the last year and a half. All of my health markers are excellent, except for LDL particle number and total, and it is the large buoyant type. I am middle-aged (46). I did get both a CT scan and tri-vascular scan, and got perfect scores for both. That alleviated any concerns that I might have previously had. Since this diet has improved my gut issues, bodyfat, blood pressure, insulin, blood glucose, mood, energy, A1C, CRP, etc., - basically every single health parameter I have tested, I am sticking with it! Thank you for clearing up the confusion surrounding LDL!
The ketogenic diet also may protect against the deposition of amyloid. Van der Auwera et al. [41] studied the ketogenic diet’s effects on AD using a transgenic mouse model of AD in which mice express a mutated human amyloid precursor protein gene in postmitotic neurons. These mice develop significant soluble Aβ by 3 months of age, and then brain plaques by 12 to 14 months. They also demonstrate behavioral deficits in tests of object recognition. In their study, 16 mice were fed a regular diet until 3 months of age, at which point 8 mice were switched to the ketogenic diet, without restriction on intake. After about 40 days on the diet, the animals fed the ketogenic diet had 25% less soluble Aβ in their brains. However, they did not perform any differently on tests of cognitive function than the mice fed a standard diet. The prevailing paradigm that reductions in Aβ deposition may delay progression in AD makes these findings particularly intriguing; perhaps a longer period on the ketogenic diet would reveal some behavioral differences between the two groups of mice.
The diet has been in use since 1930, so it is hardly a fad. While people who eat a lot of meat may have a shorter life, a ketogenic diet is not a meat diet. There have been many studies of this diet for serious medical conditions, and they have shown it can be sustained over time. Diet commercial will tell you; it is all about the food. Here are some sample ketogenic meals that I think anyone would enjoy. You eat lots of good healthy oils, fish, eggs, cheese, some meat, and vegetables. The diet is satisfying and easy to prepare.
Some years ago, a patient of mine, a professor at a well-known university, became interested in oxygenation therapies for cancer, used widely in the Mexican Clinics. These “oxygen” treatments were an offshoot of Dr. Warburg’s work, i.e., that cancer cells as obligatory anaerobes can synthesize needed energy supplies only via glycolysis. Therefore, the theory goes, in the presence of oxygen, particularly ozone, a form of hyped up oxygen, cancers cells, unlike normal cells, will be poisoned.
HDL cholesterol transfers the extra cholesterol from the blood to the liver for removal from the body and is also referred to as “good” cholesterol. LDL cholesterol transfers the cholesterol within the bloodstream to the parts of the body where cell repair is needed and also inside the arteries. It is also known as “bad” cholesterol. Total cholesterol is HDL and LDL cholesterol combined (4).
The weight and body mass index of the patients decreased significantly (P<0.0001). The level of total cholesterol decreased from week 1 to week 24. HDL cholesterol levels significantly increased, whereas LDL cholesterol levels significantly decreased after treatment. The level of triglycerides decreased significantly following 24 weeks of treatment. The level of blood glucose significantly decreased. The changes in the level of urea and creatinine were not statistically significant.
In some ways, it’s similar to the Atkins diet, which similarly boosts the body’s fat-burning abilities through eating only low-carb foods, along with getting rid of foods high in carbs and sugar. Removing glucose from carbohydrate foods will cause the body to burn fat for energy instead. The major differences between the classic keto and the Atkins diet is the former emphasizes healthier keto fats, less overall protein and no processed meat (such as bacon) while having more research to back up its efficacy.
The ketogenic diet exerts antiepileptic effects by improving energy metabolism in the brain and reducing brain oxidative stress. Fascinating new research suggests that the antiseizure effects of the ketogenic diet are also mediated by modulation of the gut microbiota. (28) Consumption of a ketogenic diet increases the levels of bacteria that produce GABA, the brain’s primary inhibitory neurotransmitter; this shifts neurotransmission towards inhibition rather than excitation, thus preventing neuronal hyperexcitability and seizure onset.
The diet’s strict limitation on starchy vegetables, whole grains, and fruits may lead to missing out on vitamins, minerals and other healthy compounds found in plant foods, which can lead to malnutrition, Bender adds. A true ketogenic diet could also lead to digestive and other unpleasant side effects. It requires monitoring and nutritional supplements. It can be difficult to follow.

In conclusion, all the mechanisms described above lead to systemic modifications and a dynamic metabolic homeostasis, in which the interplay among KB, glucose levels, mitochondrial function, synaptic neurotransmitters, and channel modifications can lead to changes in the seizure threshold and hyperexcitability. These changes contribute to the final antiseizure mechanism of KD.
In one week my husband lost 1.5 kg because of Keto diet and recipes. Thank you for the insights and tips. I would like to have a complete recipe for meals everyday and hoping by subscribing I will receive try my mail. I will keep u posted. It takes 2 to tango. The one who wants to diet must be cooperative with the plan and execution while the other person who is preparing the food must be patient to the dieting person. Its not easy to change meals so patience is required
Here’s an interesting thing that came out in Cholesterol Clarity. One of my experts, and we had 29 experts in the book that I quoted from, was Chris Masterjohn, and he said in traditional cultures, where there’s no heart disease at all, the normal level of total cholesterol for people in 6o-80s, want to guess? Of course if you read my book, you know.
The mainstay of treatment for epilepsy is pharmaceutical intervention. As I recently noted, more and more we are seeing surgical procedures being performed for those individuals who have not had a significant improvement with drugs. I indicated that at least some individuals are gluten sensitive and may benefit from a gluten-free diet which potentially could keep them from undergoing potentially life-threatening surgery as a treatment for their epilepsy.
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.”

For cells to maintain a healthy status, oxidants and antioxidants have to be in balance with each other. When this equilibrium is tilted toward an oxidized state, it leads to oxidative stress, in which an excess of oxidants can damage cellular structures and affect the health of the cell. Even cancer cells need to safeguard themselves against this.
So why the hate for meat you might ask?? I’ll give you 2 things to ponder that are observations at best. 1) Sugar, and all the tasty frakenfoods we make with it, make up a multi billion dollar food industry. 2) there is an anti-meat morality sentiment/culture that has grown and condemning meat “saves the animals” —-If you look at who funds the studies that are quick to point a finger at meat for all the diseases in modern society (even though its been our primary source of nutrition forever and doesn’t explain the increase in disease from non existent to probable), you’ll usually find that the “research” was funded by someone tied into the food industry or the animal rights industry.
Clearly, ketogenic diets are not ready for prime time as a treatment for cancer, either alone or in combination with conventional therapy. Unfortunately, that hasn’t stopped it from being touted by all manner of alternative cancer practitioners (i.e., quacks) and others as a cancer cure that “they” don’t want you to know about or saying things like, “…it’s nothing short of medical malpractice and negligence to fail to integrate this type of dietary strategy into a patient’s cancer treatment plan,” as Joe Mercola did. Dr. Seyfried himself has contributed to the hyperbole quite a bit as well. For example:
First of all, myeloma patients, even when diagnosed with an aggressive form, often linger for years before the disease advances. I would never have included such a two-year survivor in One Man Alone, or in any other book I have written or plan to write – unless, possibly, there has been documented significant regression of disease, not apparent in this case. I do include a case of multiple myeloma treated by Dr. Kelley in my monograph, a woman diagnosed with extensive cancer throughout her skeleton with evidence of multiple fractures.

After the intervention, researchers noted that the ketogenic diet group had decreased their VLDL by 78%, their medium VLDL by 60%, and their small VLDL by 57%. [23] Additionally, their large LDL had increased by 54%, medium LDL decreased by 42%, and small LDL decreased by 78%. [23] Overall, the average particle size increased by 2% and the LDL particle concentration decreased by 11%. [23]
After scouring the literature, he became quite attracted to the “good science” behind the ketogenic hypothesis, so under Dr. Seyfried’s direct supervision, he began the diet. Though the patient seems quite enthusiastic about his response, he admits in his note that with the diet there has been “no progression,” presumably in terms of x-ray studies, and some improvement in the blood studies. He still considers his disease as “incurable.”
Scientists published the first pilot study on the relationship between the ketogenic diet and cancer in 2011. For their study, they recruited 16 patients (12 women and 4 men) with various cancers in advanced stages. They had an average age of 50.4 years (30-65 years). All of them had metastatic tumors, which means that they grew and spread throughout the body.

• Cyclic ketogenic diet (CKD) — Whereas TKD is focused on fitness enthusiasts, CKD is focused more on athletes and bodybuilders. In CKD, you cycle between a normal ketogenic diet, and a short period of high carb consumption or "re-feeds."8 The idea here is to take advantage of the carbohydrates to replenish the glycogen lost from your muscles during athletic activity or working out.9
A systematic review in 2018 looked at 16 studies on the ketogenic diet in adults. It concluded that the treatment was becoming more popular for that group of patients, that the efficacy in adults was similar to children, the side effects relatively mild. However, many patients gave up with the diet, for various reasons, and the quality of evidence was inferior to studies on children. Health issues include high levels of low-density lipoprotein, high total cholesterol, and weight loss.[24]

Meat products make up a big part of the keto diet, but experts stress the importance of choosing quality. "Since the keto diet is based a lot on animal proteins, it's important to buy organic poultry and grass-fed, organic beef," says Aimee Aristotelous, RD. "Not only do organic selections help with limiting environmental toxins, but grass-fed options of red meats even change the composition of fats." The result, she explains, is that your body is able to better absorb those healthy fats.

Chapter 4 mentions specific issues related to use of a ketogenic diet in cancer treatment. It discusses goals, benefits, potential side effects, and monitoring progress of treatment. Chapter 5 discusses the details of planning a ketogenic diet, including the contribution of the macronutrients plus a section on fasting and intermittent fasting. The section on macronutrients includes definitions of saturated, monounsaturated, and polyunsaturated fats. This book’s acknowledgment of the importance of the inflammatory properties of omega-6 fatty acids and advice that the omega-6 and omega-3 in the diet should be balanced are worthy of note. To our knowledge, there are no popular diet books that mention the nutritional requirements for essential fatty acids. Imbalances in the ratio of omega-6 to omega-3 could negate the benefits of a ketogenic diet.
Initial studies indicate that the ketogenic diet appears effective in other metabolic conditions, including phosphofructokinase deficiency and glycogenosis type V (McArdle disease). It appears to function in these disorders by providing an alternative fuel source. A growing body of literature suggests the ketogenic diet may be beneficial in certain neurodegenerative diseases, including Alzheimer disease, Parkinson’s disease, and amyotrophic lateral sclerosis. In these disorders, the ketogenic diet appears to be neuroprotective, promoting enhanced mitochondrial function and rescuing adenosine triphosphate production.
There are some treatment centers like Care Oncology Clinic in the UK and ChemoThermia Oncology Center in Istanbul that are using ketogenic diet and fasting along with glucose inhibitors and conventional treatment like chemo. They claim to be getting good results, but I don’t know much about these cancer centers above and beyond what I just told you. Note that keto only seems to work with the faster-growing cancers like breast cancer, but not as much with slower-growing cancers like prostate cancer.
Ellen Davis, MS, is an expert on ketogenic nutrition and is an accomplished author and alternative-health advocate. Her website, Ketogenic Diet Resource, offers information and books on how to treat diabetes, cancer and other diseases with a ketogenic diet and provides a comprehensive source of information and tools for customizing a ketogenic diet plan to fit a range of health goals.

No single food can cure cancer, but some research has shown a link between the keto diet and slowed growth of some types of tumors in mice. A few studies in humans with certain types of brain tumors have also shown promise. On the contrary, a very low-fat diet has been found to reduce risk of recurrence for certain types of breast cancer. Some researchers are conducting more clinical trials with cancer patients, looking at how diet affects patients, along with chemotherapy and radiation. We hope that this research, as well as future research, will help us better understand the role that the keto plays in cancer.
Notably, there is a relationship between metabolic and epigenetic modifications. Shimazu et al. (2013) observed that βOHB inhibits class I histone deacetylases. During the KD, the elevation of βOHB causes changes in large-scale gene transcription but particularly those linked to oxidative-stress resistance factors. This result emphasizes that the KD has a potential role as a disease-modifying treatment in epilepsy.
The reason you’re hungry is that was not a high fat diet. That was a high protein meal that you had. While yes adding a little bit of fat is good, maybe a little more might be helpful in order to stay down those hunger things and what the hunger is, is your blood sugar being so high you can’t get it down because there’s this big long G word we talked about in my book Keto Clarity, called gluconeogenesis. When you eat more protein than your body can use, it actually can’t store protein. What it does is it sends that excess protein to the liver. The liver squirts out glucose, which is sugar. If you’re trying to be ketogenic, if you’re trying to control your blood sugar levels, you absolutely need to keep carbs low. That’s duh. You also need to moderate down on the protein. Especially if you’re insulin-resistant.
The low glycaemic index treatment (LGIT)[49] is an attempt to achieve the stable blood glucose levels seen in children on the classic ketogenic diet while using a much less restrictive regimen. The hypothesis is that stable blood glucose may be one of the mechanisms of action involved in the ketogenic diet,[9] which occurs because the absorption of the limited carbohydrates is slowed by the high fat content.[5] Although it is also a high-fat diet (with approximately 60% calories from fat),[5] the LGIT allows more carbohydrate than either the classic ketogenic diet or the modified Atkins diet, approximately 40–60 g per day.[18] However, the types of carbohydrates consumed are restricted to those that have a glycaemic index lower than 50. Like the modified Atkins diet, the LGIT is initiated and maintained at outpatient clinics and does not require precise weighing of food or intensive dietitian support. Both are offered at most centres that run ketogenic diet programmes, and in some centres they are often the primary dietary therapy for adolescents.[9]

That plan didn’t allow much variety or leeway. Eggs, two small green salads a day, gelatin for dessert, cheese (up to 4 ounces daily), bone broth, no-calorie liquids, and lots of meat: That was pretty much it for the first week. After level one, you added vegetables like broccoli. Yes, you would be in ketosis doing the original Atkins diet, but for most people, that spartan plan would get boring quickly.

Importantly, cholesterol doesn’t travel around your bloodstream on its own. As a hydrophobic (water-repelling) substance, it must be packaged within lipoproteins to move around the bloodstream. So that means when we talk about blood cholesterol levels, we’re referring to the amount of cholesterol contained in different lipoprotein particles. In addition to cholesterol, these lipoprotein particles also contain special proteins called apolipoproteins, triglycerides and other compounds.
In relation to overall caloric intake, carbohydrates comprise around 55% of the typical American diet, ranging from 200 to 350 g/day. The vast potential of refined carbohydrates to cause harmful effects were relatively neglected until recently. A greater intake of sugar-laden food is associated with a 44% increased prevalence of metabolic syndrome and obesity and a 26% increase in the risk of developing diabetes mellitus. In a 2012 study of all cardiometabolic deaths (heart disease, stroke, and type 2 diabetes) in the United States, an estimated 45.4% were associated with suboptimal intakes of 10 dietary factors. The largest estimated mortality was associated with high sodium intake (9.5%), followed by low intake of nuts and seeds (8.5%), high intake of processed meats (8.2%), low intake of omega-3 fats (7.8%), low intake of vegetables 7.6%), low intake of fruits (7.5%), and high intake of artificially sweetened beverages (7.4%). The lowest estimated mortality was associated with low polyunsaturated fats (2.3%) and unprocessed red meats (0.4%). In addition to this direct harm, excess consumption of low-quality carbohydrates may displace and leave no room in the diet for healthier foods like nuts, unprocessed grains,  fruits, and vegetables.
But no fear, there’s always a new miracle around the corner, and in 1998 the newspaper reporters and TV newscasters, having effortlessly drifted away from interferon and interleukin-2 and the bone marrow transplant craze, were all in a tizzy over the newest “final” solution to cancer, anti-angiogenesis, based on the pioneering work of the late Dr. Judah Folkman of Harvard. Dr. Folkman had spent decades studying the process of angiogenesis in cancer tissues, the formation of new blood vessels that allow tumors to grow quickly and invade through normal tissues and organs with deadly effect.
However, in most cases, avoiding all foods that contain cholesterol (like eggs or cheese) isn’t necessary to support heart health, especially since some sources of cholesterol can be nutrient-dense foods. What’s important is practicing moderation and finding balance in your diet, as well as eating a combination of natural foods that fight inflammation.
