Some of the most exciting research on the ketogenic diet pertains to its applications in the treatment of cancer. A rapidly growing collection of animal studies indicates that the ketogenic diet has anticancer effects in malignant glioma, neuroblastoma, prostate cancer, and colon cancer. (34) In humans, a ketogenic diet has been found to work synergistically with antineoplastic agents in the treatment of malignant glioma, a common primary brain tumor that is notoriously difficult to treat. (35) Several small studies indicate that the ketogenic diet improves body weight and blood profiles while reducing a marker for tumor progression, TKTL1, in patients with breast, prostate, colon, melanoma, and lung cancers. (36, 37)


Adhering to a keto diet can be challenging and may be particularly so for cancer patients, many of whom may be enduring side effects from treatment. Entering a state of ketosis requires following a strict diet-plan, comprised of high fat foods such as bacon, heavy cream, and butter, while simultaneously restricting other categories of food, such as starchy vegetables like sweet potatoes, whole grains, and certain fruits. This dramatic change in eating habits can lead to nausea and digestive upset in addition to unintentional weight loss and increased risk of malnutrition.
After I finished my conventional immunology training under Dr. Good, in 1987 Bob graciously offered me a job in his clinic, not to work with patients seeking dietary or general nutritional advice, but to help supervise a cancer unit he was then in the process of establishing. Though I was grateful for the proposal, I turned him down, determined to set up my own practice. 

More research needs to be performed to investigate the source of these relationships as well as the molecular mechanisms through which HDL operates. However, there is a general consensus among clinicians and scientists that HDL-cholesterol is healthy for the body and that higher levels of HDL-C are healthy for the body. [8] In fact, one study observed that, with every 1 mg/dL reduction in HDL cholesterol, diabetes risk increased by 4%. [9]

Having tempting, unhealthy foods in your home is one of the biggest reasons for failure when starting any diet. To maximize your chances of success with the keto diet, you need to remove as many triggers as you can. This crucial step will help prevent moments of weakness from ruining all your hard work.If you aren’t living alone, make sure to discuss with your family or housemates before throwing anything out. If some items are simply not yours to throw out, try to compromise and agree on a special location so you can keep them out of sight.
This book is an excellent source for those who want to know much of the details about a Ketogenic diet for cancer but who need it succinctly. Miriam Kalamian's book has more detail, but I have had friends tell me it was more than they wanted to know. For those people Ellen Davis's book would be best. There were some things I learned from Davis that I did not learn from Kalamian. The only problem with Davis is that there is NO INDEX. That means if you want to go back to something you remember, you have no quick and easy way to find it. Because of that I wound up reading it 3 times, each of which had value. However, I would have appreciated an index. But the book has so much that I did not want to take away a star. When I find something of value in a book, I mark it up. My copy has marks all over.
For patients interested in the keto diet, a more moderate approach may be advised. There is evidence that cutting down on the amount of refined carbohydrates in typical diets and increasing the amount of healthy fats consumed can be beneficial to one’s overall health. Before altering your diet in any way, you should always consult with your doctor and registered dietitian.
• Your body is still growing — In one study, epileptic children experienced a reduction in symptoms and improved cognitive performance when a ketogenic diet was introduced.49 However, this may have a negative effect on the growth of their bodies in the long run, according to a study published in the journal Developmental Medicine & Child Neurology.50
This is because the triglycerides from those fat cells are metabolized for energy while the cholesterol is not. The cholesterol is simply released into the blood where it will remain until removed by the liver, making it appear that our cholesterol has suddenly skyrocketed. Many people are quick to assume that this is due to an increase in dietary fat and cholesterol intake.
As you’ve looked into the keto diet, you’ve probably read that sugar is our primary fuel source, and this is true — but cancer cells handle glucose a bit differently. At rest, for example, our healthy cells will not produce lactic acid. Conversely, cancer cells have such an issue with normal energy metabolism that it essentially can only burn glucose in a way that produces lactic acid. By producing energy in this way, the cell will become more and more cancerous as it makes itself vulnerable to further mutations without any hope of repair.
I’m 46 and just had my cholesterol checked for the first time since I was 30. When I took it at 30 I hadn’t fasted and it was 133. Todays results came in at 242! Ive been doing Keto now for almost 2 years. I freaked out at first but after reading some articles I’m starting to feel better about my numbers. I won’t bore you with them but from all I’ve read I’m not at risk for heart disease as I first thought. Thanks for everyone who commented above, you’ve helped calm me 🙂
He followed her advice, refused radiation, came to see me, and over the years he has proven to be a very vigilant, determined and compliant patient. Within a year on his nutritional program, which includes a high carb diet, his pain had resolved, his energy, stamina, and concentration had improved, and scans confirmed total resolution of all his original extensive disease – in complete contradiction to what Dr. Seyfried would predict or claim possible.
Although many hypotheses have been put forward to explain how the ketogenic diet works, it remains a mystery. Disproven hypotheses include systemic acidosis (high levels of acid in the blood), electrolyte changes and hypoglycaemia (low blood glucose).[19] Although many biochemical changes are known to occur in the brain of a patient on the ketogenic diet, it is not known which of these has an anticonvulsant effect. The lack of understanding in this area is similar to the situation with many anticonvulsant drugs.[56]
One dubious practice of some keto diet adherents is using urine, blood or breath test kits to check their circulating ketone levels. While those kits can tell you if your body is indeed burning ketones instead of glucose, Westman says there’s no good evidence that one ketone level is better than another. “The level of water in a stream doesn’t necessarily tell you how much water is flowing through it,” he says. “In the same way, measuring the level of ketones in the blood doesn’t tell you the whole story.”

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]
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]
[57:08] – While the experiment worked, in that it showed a decrease in lipid levels, other markers such as postprandial glucose levels increased. Dave talks about the importance of informing yourself, finding a balance and listening to how the body feels. He also talks about plans to continue experimenting with different levels but taking into account different risk-factors. Ultimately, he prefers a lower ketogenic ratio. (Listen to Emily Maguire talk working about different macros)

The keto diet works by eliminating carbohydrates from the your daily intake and keeping the body’s carbohydrate stores almost empty, therefore preventing too much insulin from being released following food consumption and creating normal blood sugar levels. This can help reverse “insulin resistance,” which is the underlying problem contributing to diabetes symptoms. In studies, low-carb diets have shown benefits for improving blood pressure, postprandial glycemia and insulin secretion. (7)
If you participate in exercise that involves explosive movements such as jiujitsu, mixed martial arts, CrossFit, or even some rigorous forms of dance, you may benefit from a moderate carbohydrate intake rather than a ketogenic diet. Explosive movements draw on your muscles’ glycolytic capacity, which is powered by glucose from dietary carbohydrates. Endurance athletes, on the other hand, may thrive on a ketogenic diet because their respective activities can be adequately fueled by fatty acid oxidation and ketones.

In this same chapter, there are also two case reports, neither very impressive. The first, written by the mother, tells the story of a four-year old child diagnosed in 2004 with a low-grade (less aggressive) but quite large and inoperable brain tumor. The parents, as the mother writes, entrusted their child into the hands of the experts, who prescribed the usual “gold standard” treatments, which are not clearly described initially but presumably mean chemotherapy and perhaps radiation.


Net carbs is simply total carbs minus fiber and non-digestible sugar alcohols, like erythritol. (This doesn’t apply to high glycemic sugar alcohols, like maltitol.) We don’t have to count fiber and certain sugar alcohols in net carbs, because they either don’t get broken down by our bodies, are not absorbed, or are absorbed but not metabolized. (Read more about sugar alcohols here.)


Dirty keto diet: “Dirty” is the apt term, as these version of keto follows the same strict percentages (75/20/5 of fat/protein/carbs) but rather than focusing on healthy versions of fat like coconut oil and wild salmon, you’re free to eat naughty but still keto friendly foods like bacon, sausage, pork rinds, diet sodas and even keto fast food. I do NOT recommend this.
The second is called LDL-P which measures the number of LDL particles in the blood. Sometimes, there is a correlation – more LDL particles means that you can have higher levels of LDL-C. However, larger LDL molecules can grow and carry more cholesterol – leading to a discordance in which LDL-C and LDL-P are not necessarily proportional. When this happens, LDL-C and LDL-P are said to be “discordant.”
We’re also going to keep it simple here. Most of the time, it’ll be salad and meat, slathered in high fat dressings and calling it a day. We don’t want to get too rowdy here. You can use leftover meat from previous nights or use easy accessible canned chicken/fish. If you do use canned meats, try to read the labels and get the one that uses the least (or no) additives!
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.
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.
The ketogenic diet for epilepsy (KDE) was developed in the 1920s by Dr. Hugh Conklin in Michigan. But once effective medications were developed, the diet was used less frequently. It has regained recognition and study and is now a standard backup plan for children whose epilepsy symptoms are difficult to control with medication. With over 300,000 children in the U.S. with seizure disorders, this has become an important addition to the arsenal of treatments for epilepsy. Researchers are beginning to see how it might help adults and people with a variety of neurologic disorders.

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.


In all fairness, you can do these plans without eating all those processed foods, although (let’s face it!) convenience and cravings mean you’ll likely be tempted to try them. And they tap into that weakness for "cheating" by making these options easily available. Who would refuse comfort food that is "compliant" with a diet? You can have your cake and eat it too, literally. I call this pseudo-dieting. Even then, eating potentially reactive foods like dairy (which is allowed from the very beginning on Atkins) can either aggravate or trigger food sensitivities ("no bueno").
Dominic D’Agostino has argued that the mutations that are often observed in cancer may be secondary to mitochondrial dysfunction because injured mitochondria produce volatile compounds called reactive oxygen species (ROS), and these ROS can damage DNA. In this view, it may be that mitochondrial dysfunction comes first, and then that’s what leads to the mutations that are often observed in cancer.
They need to make a lot of ATP, and quickly, to support their high requirements for energy. Adenosine triphosphate, also known as ATP, is a compound that provides energy to drive hundreds of thousands of biochemical processes in living cells. Found in all forms of life, ATP is often referred to as the chemical energy “currency” that powers metabolic activity.
This device measures the amount of acetone (another ketone) you release in your breath when you are in ketosis. (Acetone is also the ketone responsible for bad breath when you’re in ketosis.) There are a number of kits on the market. One study showed they are as effective as ketone strips for testing ketone levels, but critics argue both have drawbacks including testing for only one specific ketone.
Feel free to practice cyclical ketosis (maybe doing a ketogenic diet five days a week and going higher in healthy carbs the other two days) or whatever works for you. I’ve never heard an expert say you should be in ketosis 24/7, and militantly sticking with this plan can ultimately stall your goals. Once you’re in a state of ketosis, you can transition to a more flexible ketogenic plan. You can rotate complex carbs, like sweet potatoes, pumpkin, and butternut squash, into the diet every three to four days to maintain your glycogen stores if you work out and lift weights regularly.
Low-carbohydrate high fat diets (LCHF diets) consistently improve all other markers of cardiovascular risk — lowering elevated blood glucose, insulin, triglyceride, ApoB and saturated fat (especially palmitoleic acid) concentrations, reducing small dense LDL particle numbers, glycated haemoglobin (HbA1c) levels, blood pressure and body weight while increasing low HDL-cholesterol concentrations and reversing non-alcoholic fatty liver disease (NAFLD).
Researchers believe that the ketogenic diet can also help patients with schizophrenia to normalize the pathophysiological processes that are causing symptoms like delusions, hallucinations, lack of restraint and unpredictable behavior. One study found that the keto diet lead to elevated concentrations of kynurenic acid (KYNA) in the hippocampus and striatum, which promotes neuroactive activity. Some studies even point to the elimination of gluten as a possible reason for improved symptoms, as researchers observed that patients with schizophrenia tended to eat more carbohydrates immediately before a psychotic episode. (19)

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.
It’s not heart healthy because it’s raising inflammation. The reason they put in on there though is it does one thing on your cholesterol panel that they think is good. It lowers the LDLC number. It does. It will do it all day everyday. You can sit there and drink Canola oil, and your LDL will go down, your LDLC. That LDLC is just a calculated number using this thing called the Friedewald equation and it’s not directly measured. That’s another thing people don’t realize. LDLC is just totally an estimated number. When your triglycerides are under 100 and your HDL is over 50, it totally miscalculates what your LDL is. That’s why that NMR lipo profile test to know the particles is so important. I know I’m talking fast and saying a lot of technical terms.
I have studied fasting fairly extensively, done many 10-30 day fasts, and have said to my spouse if I ever got a cancer diagnosis I would immediately fast, but since learning more about ketogenic diets, which have most of the same benefits, I would go that route without question. I recently heard that chemotherapy is only successful in 40-50 % of the time. My impression is that the average person believes chemo and radiation are far more successful than they are in fact.
A recent 2017 study of over 2,500 adults looked at fasting insulin and high-sensitivity C-reactive protein (hs-CRP), an inflammatory marker considered a strong predictor of heart attack risk. In this study, people with the highest insulin levels were more than four times as likely to have an elevated hs-CRP value compared to those with the lowest insulin levels. By contrast, elevated LDL cholesterol levels showed no association with hs-CRP (4).
I’m not going to shell out 20k to know my LDL-P. I’d rather assume that I’m part of the 30% who reacts to saturated fat with elevated LDL-P. Should I be worried, considering all my other markers point to the right direction? Expert after expert say that we don’t know what these mixed signals mean until there is a study of people doing low-carb high-fat diets, correlating their lipid profiles with incidence of cardiovascular disease.
The book summarizes, then enlarges upon, the concepts of Otto Warburg, MD, the great German scientist who won the Nobel Prize in Medicine and Physiology in 1931 for his work on cellular oxidation and energy production. No scientist has ever been nominated more frequently for the cherished Prize than Dr. Warburg, but he lost his chance for a second win, according to some sources, in 1944 after Hitler ordered that no German scientist could accept the award.
The take-home message here is that patients with epilepsy have options beyond simple pharmaceutical intervention, and these include dietary changes which well-respected science is now validating as having significant efficacy. A fundamental cornerstone of the Grain Brain Program is profound reduction of carbohydrates and sugars while increasing “good” dietary fats. This approach tends to favor a low grade of ketosis which may well be the normal state of human metabolism. I have written extensively both on the site and in Grain Brain how this dietary approach has profound health-related benefits that relates to weight loss, metabolism, energy, reduction of inflammation, and even reduce risk for diabetes and cancer. This new report offers up yet another benefit to a higher fat lower carbohydrate dietary approach, in this case, for a disease that is devastating for so many.
Ketogenic diet is one of the oldest forms of medical treatment for epilepsy. Most ketogenic diet centres have traditionally specialized in treating children ages 0 to 18 years of age. However, there is growing evidence that shows its usefulness in controlling seizures in adults. In the content below, you will find answers to frequently asked questions about the benefits and challenges of this diet therapy. Please note, the ketogenic diet should never be attempted on your own. It should only be attempted with the support of a trained medical team.
Your current cholesterol levels l is higher than I would personally feel comfortable with. I would consider making a few dietary changes (i.e., increasing fiber and net carbs, reducing saturated fat, and increasing protein), especially given your lack of improved cognition and decreased ability to work out. I wish you the best of luck going forward. - Franziska
They’re totally ignoring HDL. They’ll say, “Oh yeah, it looks good. But oh my god your LDL is bad or your total cholesterol is bad.” The other thing that they’re ignoring about your cholesterol panel which doesn’t necessarily show up in your numbers that they look at is the triglycerides. If you’ve got your numbers and you’re looking at them now, go grab them and let’s look at them. If you have a triglyceride number over 100, I know they say the range is 150 or below but over 100 means you’re eating way too many carbohydrates in your diet still. The tell tale sign that you’re eating low carb, high fat, keto very well is your triglycerides will be sub 100 and then sub 70 optimally.

Your child will begin the ketogenic diet within 24 hours of being admitted to the hospital. The diet contains a fixed amount of calories, carbohydrate, fat, and protein. Each meal has to be measured exactly and all the ingredients weighed in this diet. For young infants, pre-made, ready-to-use ketogenic formulas are available for use. Your child may also need supplements such as vitamins and extra calcium.
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]
What this shows is that there is very little difference in heart disease risk relative to total cholesterol above and below 200. In fact, no significant increase in risk was measured until total cholesterol reached an excess of 240. There also seems to be a protective role that having a total cholesterol above 180 serves both for heart disease and healthy mental function.
For many years, LDL-C tests have been used as the primary method of measuring LDL in the blood. It is cheaper and easier to measure. Recent research has called into questioning how effective LDL-C is compared to LDL-P in precisely assessing cardiovascular risk. After reviewing cross-sectional data, a recent peer-reviewed paper from the world-renowned Framingham Heart Study stated that 

The authors defined a VLCKD as a diet lower in 50g of carbohydrates – lower than the daily recommended grams of carb consumption clinicians recommend to diabetics. They included 13 randomized controlled studies with a total of 1,415 subjects. All studies took place for at least a full year and all subjects included were over 18 years old and had a BMI of at least 27.5 kg/m2. In each of these studies, VLCKD diets were compared to low-fat diets.

I enjoyed reading this book. The book takes you from the fact that cancer cells addict glucose to why and how ketogenic diet (low carbohydrate high fat diet) can help to fight and cure cancer. It also helps patients to customize their diet and provides cooking techniques. As I lost my uncle due to cancer, I felt Ellen Davis words "I wish with all my heart that I had known then what I know now"
I’ve never had a patient who ate so much broccoli she got knocked out of ketosis. Once you’re getting sufficient dietary fat, you can incorporate tons of leafy and cruciferous vegetables, low-sugar fruit like berries and avocado, and even some starches like quinoa into your ketogenic plan. Your mileage may vary, of course, but even focusing on low-sugar vegetables will add an array of key nutrients to your meals.
So, what evidence does Dr. Seyfried himself provide to prove his point that the best diet for all cancer patients, whatever the type, is the ketogenic, high fat, no carb diet? Well, very little. Certainly the 400 plus pages of elaborate biochemistry and theory are impressive and informative. But in terms of practicalities, that is, results with actual human patients diagnosed with cancer, there is next to no evidence.
More specifically, subjects in the lowest third of carbohydrate consumption had an HDL concentration of 1.21 mmol/L while subjects in the highest third had HDL concentration of 1.08 mmol/L. [13] According to the authors, “every 100-g/d increment of carbohydrate (approximately the difference between the top and bottom tertiles) was associated with 0.15-mmol/L less of HDL.” [13]
After my original lengthy conversation with Dr. Kelley, my research mentor Dr. Good suggested that during my summer break I begin an informal review of Kelley’s patient charts located in his Dallas office. From my first day in Dallas, I found among Kelley’s records patient after patient with appropriately diagnosed poor prognosis or what would be considered terminal disease such as metastatic pancreatic and metastatic breast cancer, who had done well under his care for many years, often with documented regression of his disease.
This describes me, too. I am not a doctor, but after months and years of research, have decided to follow the ketogenic lifestyle and the naturopathic cancer treatments prescribed by my physician. It took a few months to find a doctor who embraced this, but he is worth it. Keto had my diabetes under control long before we realized that cancer was trying to get me as well. I take no chemical drugs for anything. Diet, exercise, and a few supplements take care of my health needs. You don’t know me, but three years ago, I needed a walker and a wheelchair. Today at 60, I walk under my own power and ride a bicycle as much as possible. Go as natural as you can, it helps. Stay away from “products” and just eat fresh, whole, natural food. (The article shows these.)
You may find it easy to eat less when all you can eat is protein and fat. But after a while, you may grow tired of bringing your own whole salmon to parties, and wonder what the other 95% of the grocery store is up to. You may start to have fantasies about a threesome: you, Oreos, and chocolate sauce. Not only that, you may be getting some serious scurvy and other nutrient deficiencies.
The keto diet works for such a high percentage of people because it targets several key, underlying causes of weight gain — including hormonal imbalances, especially insulin resistance coupled with high blood sugar levels, and the cycle of restricting and “binging” on empty calories due to hunger that so many dieters struggle with. In fact, these are some of the direct benefits of the keto diet.

Wondering what fits into a keto diet — and what doesn’t? “It’s so important to know what foods you’ll be eating before you start, and how to incorporate more fats into your diet,” says Kristen Mancinelli, RD, author of The Ketogenic Diet: A Scientifically Proven Approach to Fast, Healthy Weight Loss, who is based in New York City. We asked her for some guidelines.
Stock up: Jet.com's new City Grocery service (available in select markets) makes it easy to ensure you always have keto-friendly veggies in the fridge. We love their delivery scheduling tool; simply fill your cart, then decide which day and timeframe you'd like your groceries delivered. One of our faves: Urban Roots Green Squash Veggie Noodles are great for whipping up low-carb "pasta" dishes.
In a model of PD, neurons cultured from the developing mesencephalon, the site of the future substantia nigra, are susceptible to injury and death from the application of 1-methyl-4-phenylpyridinium (MPP+), which inhibits mitochondrial energy production. Adding one of the ketone bodies, β-hydroxybutyrate, rescues these cells from death and reduction in neurite outgrowth [37]. In an in vivo model, mice treated with β-hydroxybutyrate via continuous subcutaneous infusion were relatively protected from the dopaminergic degeneration induced by injection of MPTP, an MPP+ precursor, apparently by enhancing oxidative phosphorylation and the production of ATP [38].
Everyone talks about upping their fats… I do not think that is the key to sweeping LDL out of the system. Upping cruciferous fiberous veggies… the fiber, vitamins and minerals contained in veggies bind with the LDL and move it on out. You would have to eat literally a truck load to make any serious dent in your daily carb allowance since most are very low net carb anyways.
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.
Although the exact role of the keto diet in mental and brain disorders is unclear, there has been proof of its efficacy in patients with schizophrenia. And, to boot, it works to reverse many conditions that develop as a side effect of conventional medications for brain disorders, like weight gain, type 2 diabetes and cardiovascular risks. More research is needed to understand the role of the ketogenic diet in treating or improving schizophrenia, as the current available studies are either animal studies or case studies, but the benefits of a low carbohydrate, high-fat diet in neurology is promising.

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. 

25-30 grams a day is about my max with carbs, which my avocado … when I have avocado, that’s about half of that allotment. I have to be real careful with that. My protein is about 80-100 grams. Doesn’t sound like a lot, I’m 6 foot 3, I’m doing my standing work desk here … 6 foot three in a big guy, 80-100 grams doesn’t sound like a lot but if I go over that I start having that gluconeogenesis kick in, and I can see it on my blood sugar monitor and I can see it on my blood ketone monitor. They go in the wrong direction. You have to be real mindful. Then you’re like, okay you cut the carbs, you moderate the protein, well then what do you eat? Hmm.
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]
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.

Agreed. The big problem is that a person can't (or shouldn't) get a CACS often enough to prove that a dietary change will make a difference. Calcification is usually slow & the radiation from the scan isn't trivial. Medical professionals or patients can jump to a conclusion & remedy/change their diets immediately. I would go with the person's instincts (do you feel better on this diet?) & get the appropriate scanning tests done after a sizeable interval.  
Further, these experts believe that DNA mutations, uncontrolled cellular growth, and other hallmarks of cancer are a consequence, not the cause, of impaired energy metabolism. They suggest that the poor rate of success in the “War on Cancer” has to do with mainstream medicine’s failure to recognize mitochondrial dysfunction as the underlying cause of cancer.
Don’t expect to turn into a muscle-bound. There is unfortunate hype surrounding this diet. There are no magical “ketone” supplements that turn you thin. But studies show it might improve your thinking, help with type 2 diabetes, dementia, seizures and inflammation. Every diet has its detractors. Recent “news” has been particularly harsh with dramatic headlines. Some considered it a “fad.” Others question sustainability. So, are they right?
Preclinical evidence indicating the effect of a KD on tumor growth and progression. The bar chart shows the number of preclinical studies, which investigated the effect of a KD on different types of cancer. Colors of the bars represent the result of each study as indicated in the color key. Studies on KD and cancer were collected by a literature search covering through the end of 2017. R indicates studies with a calorie-restricted KD; T indicates use of a KD as an adjuvant therapy to classic therapy.
These studies are all in combination with either radiation or chemotherapy. My preference is to start metabolic therapy with GBM (glioblastoma multiforme). This is a devastating type of brain cancer. Metabolic therapy with a restricted KD could be done with a few tumors where you know the conventional standard of care doesn’t work at all. You would choose those kinds of patients and do a clinical trial based on historical controls and see what the outcome would be and see if you could get some level of survival that would match or be better than the conventional standard of care.
The ketogenic or “keto” diet is a low-carbohydrate, fat-rich eating plan that has been used for centuries to treat specific medical conditions. In the 19th century, the ketogenic diet was commonly used to help control diabetes. In 1920 it was introduced as an effective treatment for epilepsy in children in whom medication was ineffective. The ketogenic diet has also been tested and used in closely monitored settings for cancer, diabetes, polycystic ovary syndrome, and Alzheimer’s disease.
People suffering from diabetes and taking insulin or oral hypoglycemic agents suffer severe hypoglycemia if the medications are not appropriately adjusted before initiating this diet. The ketogenic diet is contraindicated in patients with pancreatitis, liver failure, disorders of fat metabolism, primary carnitine deficiency, carnitine palmitoyltransferase deficiency, carnitine translocase deficiency, porphyrias, or pyruvate kinase deficiency. People on a ketogenic diet rarely can have a false positive breath alcohol test. Due to ketonemia, acetone in the body can sometimes be reduced to isopropanol by hepatic alcohol dehydrogenase which can give a false positive alcohol breath test result. 
Ketone bodies synthesized in the body can be easily utilized for energy production by heart, muscle tissue, and the kidneys. Ketone bodies also can cross the blood-brain barrier to provide an alternative source of energy to the brain. RBCs and the liver do not utilize ketones due to lack of mitochondria and enzyme diaphorase respectively. Ketone body production depends on several factors such as resting basal metabolic rate (BMR), body mass index (BMI), and body fat percentage. Ketone bodies produce more adenosine triphosphate in comparison to glucose, sometimes aptly called a "super fuel." One hundred grams of acetoacetate generates 9400 grams of ATP, and 100 g of beta-hydroxybutyrate yields 10,500 grams of ATP; whereas, 100 grams of glucose produces only 8,700 grams of ATP. This allows the body to maintain efficient fuel production even during a caloric deficit. Ketone bodies also decrease free radical damage and enhance antioxidant capacity.
This means that pilot studies are smaller in scale than a standard clinical trial, but they still yield important evidence and indicate which treatments should be assessed further. Typically, scientists perform pilot studies after case studies and animal studies yield promising results, which is exactly what was done regarding the keto diet and cancer.

In essence, it is a diet that causes the body to release ketones into the bloodstream. Most cells prefer to use blood sugar, which comes from carbohydrates, as the body’s main source of energy. In the absence of circulating blood sugar from food, we start breaking down stored fat into molecules called ketone bodies (the process is called ketosis). Once you reach ketosis, most cells will use ketone bodies to generate energy until we start eating carbohydrates again. The shift, from using circulating glucose to breaking down stored fat as a source of energy, usually happens over two to four days of eating fewer than 20 to 50 grams of carbohydrates per day. Keep in mind that this is a highly individualized process, and some people need a more restricted diet to start producing enough ketones.
Studies assessing the efficacy of the MAD reported seizure freedom rates of up to 25% and seizure reduction rates of up to 60% in children. One study used a simplified MAD (sMAD) and reported seizure freedom rates of 15% and seizure reduction rates of 56% in children. One study utilised a MAD in adults and reported seizure reduction rates of 35%, but no patients became seizure free (GRADE rating low).
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.
To get the most benefit from the Keto diet, you should stay physically active. You might need to take it easier during the early ketosis period, especially if you feel fatigued or lightheaded. Walking, running, doing aerobics, weightlifting, training with kettlebells or whatever workout you prefer will boost your energy further. You can find books and online resources on how to adapt Keto meals or snacks for athletic training.

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.”
As far back as the 5th century, Hippocrates noted that fasting reduced seizures, and in the 1920s a diet was developed to mimic changes brought on by fasting that could be maintained long-term, specifically to treat seizures, and thus the ketogenic diet was born.1 This original ketogenic diet was very low in carbohydrates and protein and supplied 80-90% of the calories as fat.2 3 While the original ketogenic diet was successful in treating intractable childhood epilepsy, it fell out of favor when the modern antiepileptic drugs became available. In the 1990s the diet began to see a resurgence as people once again turned to it for difficult-to-treat cases of childhood epilepsy, such as those that do not respond to medication, and as a weight loss tool. The most recent research on the benefits of the ketogenic diet and ketones, in particular, have expanded to examine its possible therapeutic effects on other neurological diseases, cardiovascular disease, diabetes and even cancer.
They need to make a lot of ATP, and quickly, to support their high requirements for energy. Adenosine triphosphate, also known as ATP, is a compound that provides energy to drive hundreds of thousands of biochemical processes in living cells. Found in all forms of life, ATP is often referred to as the chemical energy “currency” that powers metabolic activity.
The ketogenic diet has been studied in at least 14 rodent animal models of seizures. It is protective in many of these models and has a different protection profile than any known anticonvulsant. Conversely, fenofibrate, not used clinically as an antiepileptic, exhibits experimental anticonvulsant properties in adult rats comparable to the ketogenic diet.[58] This, together with studies showing its efficacy in patients who have failed to achieve seizure control on half a dozen drugs, suggests a unique mechanism of action.[56]
