Following a very high-fat diet may be challenging to maintain. Possible symptoms of extreme carbohydrate restriction that may last days to weeks include hunger, fatigue, low mood, irritability, constipation, headaches, and brain “fog.” Though these uncomfortable feelings may subside, staying satisfied with the limited variety of foods available and being restricted from otherwise enjoyable foods like a crunchy apple or creamy sweet potato may present new challenges.
A ketogenic diet derives approximately 90% of dietary calories from fat, 8% from protein, and just 2% from carbohydrates.1 In comparison, the standard American diet derives 35%, 15%, and 50% of calories from fat, protein, and carbohydrates, respectively. Although it is rising in popularity, the ketogenic diet is not a new dietary intervention. It is an established nutritional treatment approach — first developed in the 1920s — for patients who have epilepsy that is not well controlled with antiepileptic agents. The keto diet later remerged as an acceptable intervention in the 1990s.
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 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:
We also maintain a certain amount of stored sugar as glycogen, found in the liver and muscle and formed when glucose molecules link up to one another in complex chains. In times of need and if deprived of dietary carbohydrates, our liver and muscle cells can break down glycogen into glucose for release into the bloodstream. Our liver cells can also, when necessary, convert certain amino acids such as alanine into glucose.

We admit approximately four children ranging from infants to adolescents each month to participate in the therapeutic ketogenic diet program. New patients take part in a 3-day orientation (Monday through Wednesday) that starts the child on the diet and provides education for the family. After that, we follow up with the patients in our clinic every one to three months.
Certainly Dr. Seyfried has put together a most impressive achievement, chronicling in great detail his belief that cancer does not develop from genetic alterations – as is generally believed – but as a result of changes in fundamental cell physiology, specifically changes in energy production, that in turn lead to the cancer phenotype. In essence, the genes remain intact, but metabolism goes awry.
Contemporary researchers like Dr. Thomas Seyfried and Dominic D’Agostino have argued that this dysregulated cellular energy production, or cellular metabolism, is actually what induces malignancy and that by extension, if we limit the fuels available for this process of fermentation, and the fuels are glucose, which is derived from carbohydrate in the diet, and glutamine, which is derived from protein in the diet, then we can actually starve cancer cells and either improve the results of conventional treatment or perhaps even address some cancers independently without conventional treatment.
For patients interested in Ketogenic diet, it is vitally important that you talk with your health-care providers, says Alice Bender, MS, RDN, AICR’s Director of Nutrition Programs. “A dietitian is best positioned to talk with you about what is known regarding the pros and cons – especially to learn if this diet has any research showing the reasonable application with your particular type of cancer and if the ketogenic diet may even be harmful for you.”

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.
Jimmy Moore: My mamma would kill me if she know I did that. I had four root canals and then I also had some mercury amalgams that were put in way back, twenty years ago when I was in my early twenties. Anyway, I determined I bet that’s a big reason why my cholesterol has always been high since I’ve been adult. I got that taken care of the year that I wrote Cholesterol Clarity in 2013, and I got it tested my total cholesterol was over 400. Got it tested again in October, total cholesterol had dropped over 100 points.
Chronic disease continues to ravage our world today despite tremendous advances in health care. Therapeutic approaches to treating this wide-range suffering cannot be met by technological growth in pharmacology, genetic therapy, or surgery. It should be obvious that the real solution for treating cancer and disease is not found in a man-made pill but rather is found in regulating the metabolic functions within our bodies.
My Husband and I started doing Keto July 2018. We got over weight after we got out of the Marine Corps. It has been hard to workout because I became disabled, but my diet was not good. After our friend Amber recommended your site and support group, we found a lot of helpful information to get us started on a successful journey. So far it’s been one month and we have lost 18 pounds each!

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.
Now that we have a superficial understanding of the total-to-HDL cholesterol ratio, let’s look at the results of the meta-analysis. The two findings that the researcher’s highlight most are the effects that lauric acid (found in high quantities in coconut oil) and stearic acid (found in high quantities in animal fats) have on the total-to-HDL cholesterol ratio. Both of these fatty acids improved the total-to-HDL cholesterol ratio more favorably than carbohydrates [25]. (A similar pattern emerges for blood sugar and triglyceride levels when we replace carbs with fat as well.)
Though I would see Bob occasionally at conferences, I never mentioned any of this to him. Some years later we met for lunch in Washington, DC, at a conference where we were both scheduled to speak. To my astonishment, he told me he was closing down his cancer unit completely, to concentrate on his traditional area of expertise – obesity, diabetes, heart disease, hypoglycemia, the metabolic syndrome – problems for which he knew his nutritional approach with the ketogenic diet worked quite effectively.
In adults, the type of ketogenic diet typically used is the modified Atkins diet. Carbohydrates are limited to 20 grams per day and the intake of foods containing fat is required to get into the state of ketosis. For example, foods such as heavy cream, oils, avocado, eggs, butter and meats are encouraged; whereas conventional breads, pastas, cereals and cakes are restricted.

I am very encouraged by this recent study, published in January 2014, looking at the ketogenic diet and intermittent fasting as an adjunct nutritional therapy to be administered to cancer patients undergoing standard radiation therapy in cancer treatment. The study provides “dietary interventions” to be used along side “radiotherapy”. Therefore, this is not really a study that lends itself to developing more pharmaceutical drugs. However, will physicians in the allopathic medical field seriously consider rigorous diet therapy?


Type 2 diabetes. One study found that being on the keto diet for one year reversed diabetes for up to 60 percent of participants. With an average weight loss of 30 pounds, they dramatically reduced or eliminated their need for insulin and no longer needed oral hypoglycemic drugs. The keto diet is also easier to sustain than the calorie-restricted diet or the protein-sparing modified fast.


Treatment with MAD was shown to be more effective in seizure control when the MAD was started with lower carbohydrate limits (Kossoff et al., 2010). In a randomized study with 20 children with drug-resistant epilepsy, 60% of them showed fewer seizures in the first 3 months on the MAD, with 10 g/day of carbohydrate intake against 10% of reduction with 20 g/day (p = 0.03). In the same study, after 3 months, an increase in carbohydrate intake to 20 g/day, maintained seizure control and improved tolerability, suggesting that a lower carbohydrate limit is important only in the first 3 months (Kossoff et al., 2007; Kossoff and Dorward, 2008).
One study assessed the effect of dietary interventions on quality of life, cognition and behavioural functioning, reporting participants in the KD group to be more active, more productive and less anxious after four months, compared to the control group. However, no significant difference was found in quality‐adjusted life years (QALYs) between the KD group and control group at four or 16 months (GRADE rating very low).
If your ketone value is above 0.5 mmol/L first thing in the morning, you’re in ketosis. However, a range of 0.7 to 2.0 mmol/L is optimal for most people. If your value is above 3.0 mmol/L, you may not be eating enough and/or should consider adding some carbohydrates back to your diet. However, in the long run, your goal should not be a specific number on the ketone meter, but an improvement in your symptoms.
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.
I think we obsess about numbers because we have been given a range that is supposedly the healthy, right range. Unfortunately there are a lot of mechanisms that we don’t know a lot about right now, that could be going on that makes that happen for some people in the mornings. I’ve just talked to too many of the experts, who say “Don’t worry about that. It’s really not the big deal. Keep an eye on your fasting insulin levels in the morning and even if you want to do a five hour glucose tolerance test, it’s call a 5 hour GTT, could go down to your doctor, please don’t drink that crappy glucose serum, because that will mess you up.” I actually did it one time with my co-author, he actually ran it with me … I wanted to see what would happen to my blood sugar and insulin levels when I had a low carb meal.
On the other hand, the types of foods you’ll avoid eating on the keto, low-carb food plan are likely the same ones you are, or previously were, accustomed to getting lots of your daily calories from before starting this way of eating. This includes items like fruit, processed foods or drinks high in sugar, those made with any grains or white/wheat flour, conventional dairy products, desserts, and many other high-carb foods (especially those that are sources of “empty calories”).
The American Academy of Neurology and the Child Neurology Society recommend adrenocorticotropic hormone (ACTH) as the first line of therapy for infantile spasms. The goals for this medication are to completely stop the infantile spasms and improve the abnormal EEG. In some cases, pediatric neurologists prescribe the seizure medication Sabril® (vigabatrin), especially for patients with tuberous sclerosis. Both drugs work well, but your child's doctor will talk with you about which medicine may be the better choice for your child.
The ketogenic diet achieved national media exposure in the US in October 1994, when NBC's Dateline television programme reported the case of Charlie Abrahams, son of Hollywood producer Jim Abrahams. The two-year-old suffered from epilepsy that had remained uncontrolled by mainstream and alternative therapies. Abrahams discovered a reference to the ketogenic diet in an epilepsy guide for parents and brought Charlie to John M. Freeman at Johns Hopkins Hospital, which had continued to offer the therapy. Under the diet, Charlie's epilepsy was rapidly controlled and his developmental progress resumed. This inspired Abrahams to create the Charlie Foundation to promote the diet and fund research.[10] A multicentre prospective study began in 1994, the results were presented to the American Epilepsy Society in 1996 and were published[17] in 1998. There followed an explosion of scientific interest in the diet. In 1997, Abrahams produced a TV movie, ...First Do No Harm, starring Meryl Streep, in which a young boy's intractable epilepsy is successfully treated by the ketogenic diet.[1]

Because some cancer cells are inefficient in processing ketone bodies for energy, the ketogenic diet has also been suggested as a treatment for cancer.[59][60] A 2018 review looked at the evidence from preclinical and clinical studies of ketogenic diets in cancer therapy. The clinical studies in humans are typically very small, with some providing weak evidence for anti-tumour effect, particularly for glioblastoma, but in other cancers and studies, no anti-tumour effect was seen. Taken together, results from preclinical studies, albeit sometimes contradictory, tend to support an anti-tumor effect rather than a pro-tumor effect of the KD for most solid cancers.[61]


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.

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.

In the first week, many people report headaches, mental fogginess, dizziness, and aggravation. Most of the time, this is the result of your electrolytes being flushed out, as ketosis has a diuretic effect. Make sure you drink plenty of water and keep your sodium intake up.6One of the fathers of keto, Dr. Phinney, shows that electrolyte levels (especially sodium) can become unbalanced with low carb intake.


Of the many benefits of a keto diet, weight loss is often considered No. 1., as it can often be substantial and happen quickly (especially for those who start out very overweight or obese). The 2013 study published in the British Journal of Nutrition found that those following a keto diet “achieved better long-term body weight and cardiovascular risk factor management when compared with individuals assigned to a conventional low-fat diet (i.e. a restricted-energy diet with less than 30 percent of energy from fat).” (2)

This week we’re introducing a slight fast. We’re going to get full on fats in the morning and fast all the way until dinner time. Not only are there a myriad of health benefits to this, it’s also easier on our eating schedule (and cooking schedule). I suggest eating (rather, drinking) your breakfast at 7am and then eating dinner at 7pm. Keeping 12 hours between your 2 meals. This will help put your body into a fasted state.
One of the most vocal proponents of the keto-diet-as-cancer-treatment theory has been Dr. Thomas Seyfried, a cancer researcher and professor at Boston College. Several years ago, Seyfried said that the keto diet actually beats chemotherapy for some types of cancer, a claim founded in his rather controversial belief that cancer is primarily a mitochondrial metabolic disease. In a recent paper, Seyfried outlined a cancer-treatment approach that he thinks could be the "blueprint for the destruction of cancer," as he told U.S. News & World Report:

As the authors write, “the protocol was not designed to reverse tumor growth or treat specific types of cancer.” The researchers also acknowledge the patient numbers were too small to allow for meaningful statistical evaluation, even for the avowed purposes. Overall, the discussion centers on the practicalities of implementing the diet and the results of the PET scans.
The ketogenic diet is a high-fat, low-carbohydrate diet that's recently become popular for weight loss. But the diet has been used to treat epilepsy since the 1920s, according to the Epilepsy Society, a charity in the United Kingdom. Although most people with epilepsy today control their seizures with anti-epileptic drugs, the diet is sometimes prescribed to children with epilepsy who have not responded to several medications.
• Weight loss — If you're trying to lose weight, then a ketogenic diet is one of the best ways to do it, because it helps access your body fat so that it can be shed. Obese people in particular can benefit from this method. In one study, obese test subjects were given a low-carb ketogenic diet and a low-fat diet. After 24 weeks, researchers noted that the low-carb group lost more weight (9.4 kilograms or 20.7 pounds) compared to the low-fat group (4.8 kilograms or 10.5 pounds).1
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).
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.

The KetoPet Sanctuary was started in 2014 to rescue shelter dogs with terminal cancer and give them a forever home. Once at KetoPet, each dog was placed on a raw ketogenic diet (high fat, adequate protein, very low carbohydrates). We then did something that was never done before: we used PET (positron emission tomography) to image disease and validate our nutrition-first approach. While not a cure, we found a raw ketogenic diet to be effective in improving outcomes for dogs with cancer. Even more, these case studies support our belief that all dogs should eat a raw ketogenic diet optimal health.
Recent animal studies suggest a role for the ketogenic diet as a potential therapy for amyotrophic lateral sclerosis (ALS). ALS results from the death of motor neurons in the brain and spinal cord. A small number of cases are caused by an inherited mutation in the gene encoding the Cu/Zn superoxide dismutase I (SOD1). Mice expressing the mutated gene recapitulate the progressive muscle weakness and death due to respiratory failure seen in humans with ALS. Various lines of evidence suggest that mitochondrial dysfunction may play a role in the pathogenesis of ALS. A recent study suggests that ketosis induced by the ketogenic diet might affect progression of the disease [47]. Transgenic SOD1 mice fed a high-fat diet (60% of calories from fat, compared with < 10% fat in standard rodent chow and > 90% of calories from fat in a typical rodent ketogenic diet) preserved their performance on a standard rotorod test longer than those fed a regular diet. Mice were fed ad lib, and mice fed the high-fat diet gained more weight than those on the standard diet, so overall caloric restriction was unlikely to be a factor in this study. When spinal cords were examined, significantly more motor neurons were preserved in the mice fed the ketogenic diet than in those fed a regular diet. However, the ketogenic diet did not significantly prolong survival.
High levels of triglycerides in the blood are thought to be a sign of poor metabolism. Poor metabolism, or metabolic disorders, are associated with obesity, diabetes, heart disease and cancer. Often times, elevated triglycerides are a byproduct of insulin resistance. In these cases, a ketogenic diet is an excellent strategy to improve those numbers.
