Hi, I’m still a bit skeptical, I have seen some of my friends do the keto diet, and have had good results. Though I am still not sure about the idea of the fats being eaten. They say they eat meat with the fat and must do so, is this correct? Also isn’t this not good for the body especially for the kidneys? Second, can a diabetic do this diet? There are many questions running through my head.
Chris, I’m missing the logic here. Even when carbohydrates are restricted, the body is going to take fats and glycogen and turn them back into blood sugar, i.e. glucose. Glucose is also the only fuel the brain can use, and when it is too high or too low, all kinds of alarm bells go off, and the body does everything it can to restore normal glucose levels. Ketogenic diet or not, blood sugar is going to stay pretty steady if all the normal regulatory mechanisms are in place. If there is glucose in the blood, there is glucose in the interstitial fluids, and cancer cells are never going to be starved for glucose. So if restricting carbs has any use in cancer therapy, it has nothing to do with preventing cancer cells from getting glucose. If there is no glucose in the blood, you are dead.
There is nothing inherently difficult about following a ketogenic diet. We have many patients who do this very easily over many years. The metabolic benefits significantly outway any perceived challenges from limiting particular food types. Uptake would be far more widespread if nutrition professionals left their predujical opinions of SFA’s behind. Finally, given the expertise in Ketogenic Diets at Harvard, Dr David Ludwig, for one springs to mind, I am surprised the author did not avail themselves of the local expertise.
Then you’ve got "keto-approved" junk foods like cookies, candy, and bread that promise to keep you in ketosis even as you indulge in your favorite comfort foods. The flip side is ketogenic diets that include almost no plant foods, focusing instead on meat, meat, and more meat. Bring on the bacon. Slather your steak in butter. Who needs vegetables? (Hint: You do!) Ketogenic diets are a practical invitation for vegetable-phobic people, and when you skip out on gut-healing plant foods, you create microbiome mayhem.
Perhaps the first person to really put ketogenic diets on the map was Dr. Robert C. Atkins, a cantankerous medical doctor who began experimenting with a low-carb diet in 1963. His first book, Dr. Atkins Diet Revolution, was published in 1972. Dr. Atkins died in 2003 from a tragic fall (interestingly, the Atkins website’s timeline does not mention his death), but his diet plan lives on today.
More recently, the famed New York diet doctor, Robert Atkins, MD, popularized the ketogenic diet, not for cancer, but as the ultimate weight loss plan with his books over the decades selling in the tens of millions of copies. The original version of the Diet Revolution published in 1972 sold at one point more than 100,000 hard copies a week, in those days the fastest selling book in the history of United States publishing.
I’m discouraged to see that nowhere in the article nor in the comments is there a mention of a diet’s best fit to genetics. Consider if someone is an APOE E2 carrier and/or has certain polymorphisms of the APO5 gene. These are quite rare in Okinawa but much more prevalent in the USA (12% of the population). According to a number of well-designed studies, these genetic characteristics point to a higher fat, lower carbohydrate diet as beneficial and even a “moderate” carb diet as problematic.
The ketogenic diet is a natural, nontoxic metabolic therapy being studied and utilized for cancer prevention and treatment. It works because cancer cells are dependent upon a constant supply of blood sugar (glucose) to stay alive. Normal cells can make energy from both glucose and ketones (metabolic by-products of burning fat), but most cancer cells can only use glucose. Avoiding carbohydrates (starch and sugar) while enjoying delicious and healthy protein and fats will lower blood glucose and increase blood-ketone levels, resulting in a normal body state called nutritional ketosis. Research has shown that nutritional ketosis starves cancer cells while nourishing normal cells and strengthening total body health.
In 2005, he would eventually die with his dream of academic acceptance unrealized. But my colleague Dr. Linda Isaacs and I have worked diligently over the past 26 years, keeping the Kelley idea alive, that different people may require completely different diets. In the next installment, I will address my own experience treating patients diagnosed with advanced cancer with a Kelley based approach. Our therapy involves, oftentimes, diets high in carbohydrates, which proponents of the ketogenic diet would predict should fuel, not stop, cancer.
A randomised, parallel-group trial among 307 obese participants demonstrated that a low-carbohydrate, high-fat diet resulted in lower levels of diastolic blood pressure, triglyceride, and LDL cholesterol levels in the first 6 months compared to the low-fat diet group. Moreover, the HDL cholesterol increased by 23% after 2 years in the low-carbohydrate, high-fat diet group (14).
Cardiovascular Disease – A ketogenic diet is often feared because of its high dependence on dietary fat for energy. This misguided fear is based on the outdated notion that eating fat negatively affects cardiovascular health, in particular, blood lipids. On the contrary, a low-carbohydrate ketogenic diet may actually improve blood lipid profiles, including decreased triglycerides and total and LDL cholesterol, and increased HDL cholesterol.39 40 41 A ketogenic diet might also alter the size and volume of the different LDL particles in a beneficial way, shifting from small, dense particles (believed to be atherogenic) to large, fluffy particles. 42 (See the Natural Grocers Customer Literature File Fats— Saturated for more information)
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.”
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.
Mitochondria are the main power generators in our body’s cells and also play a prominent role in antioxidant activities and calcium buffering. The number of mitochondria present in any cell is directly related to its metabolic requirements, and can range from a solitary mitochondrion to thousands of them. In fact, mitochondria enable cells to generate up to 15 times more ATP than they could otherwise!
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.
If you're new to keto, watch out for hidden carbs. Generally, dairy products and nuts are a good way to meet your daily fat intake, but know that some of those items may contain more carbohydrates than you think. For example, yogurt topped with nuts may seem like a great keto-friendly snack, but a 5.3 ounce serving of plain yogurt has 12 grams of carbohydrates. Vanilla flavored yogurt has 24 grams of carbohydrates. Add an ounce of cashews, weighing in at nearly nine grams of carbs, and you’re up to 21 to 33 grams of carbs for that snack, which could knock you out of ketosis. Be sure to read nutrition labels carefully and pay careful attention to serving sizes. Track foods using a keto-specific app like Senza or KetoDiet can help you stay within your recommended daily carb intake.
In one study, a variant of the ketogenic diet was applied to children with autism [51, Class III]. This diet was a modified John Radcliffe diet, which substitutes medium-chain triglycerides for some fat, but it was administered for only 4 of every 6 weeks during this 6-month trial (ie, cycles of 4 weeks “on diet” and 2 weeks “off diet” were used for the duration of the study). This group studied children on Crete, an island with a relatively isolated population and a significant number of autistic children. Behavior was rated on the standardized Childhood Autism Rating Scale (CARS) by a blinded child psychiatrist. Of the 18 children who completed the study, 2 demonstrated significant improvement (ie, CARS score reduced by > 12 points), 8 had moderate improvement (CARS score reduced by 8–12 points), and 8 showed minor improvement (CARS score reduced by 2–8 points). Children with lower starting CARS scores (less severe autism) appeared to respond better than those more severely affected. These findings should be interpreted with caution for a number of reasons. Given the geographic isolation of Crete, there may have been a strong genetic contribution to autism in this population. Methodologically, the CARS score was not designed as a longitudinal test, making its meaning in this study unclear. Additionally, intermittent administration of the ketogenic diet has not been examined in other disorders, making it difficult to compare this intervention with other studies of the ketogenic diet. Finally, any structured intervention may be associated with improved performance in patients with autism. Further study with appropriate controls (structured diet plans, vitamin administration) is needed to confirm these findings.
Data on the efficacy of KD and the modified Atkin’s diet (MAD) in children and adults are similar.1 “Approximately one-third of adults with epilepsy that does not respond to medications may have a 50% seizure frequency reduction. Five to 10% of these adults may have a dramatic response, with greater than or equal to 90% seizure frequency reduction. This is similar to the response seen in children,” said Klein.
To test whether energy reserves in hippocampal neurons were enhanced with the KD, they counted the number of energy "factories," or mitochondria, within cells using electron microscopy. They found that KD treatment significantly increased the number of mitochondria per unit area in the hippocampus. This finding, along with the concerted increase in the expression of genes encoding energy metabolic enzymes, led them to conclude that KD treatment enhances energy production in the hippocampus and may lead to improved neuronal stability.
[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)
One of the biggest concerns when it comes to following the ketogenic diet is that some people are afraid to try this way of eating simply because they think it can increase their cholesterol and clog their arteries. From the solid scientific studies we will talk about below, a low-carb ketogenic diet is shown to improve your cholesterol levels and can be an incredibly healthy choice.
Collectively, these findings suggest that LDL particle size is a more precise indicator of future cardiovascular illness than total LDL cholesterol even when people have high levels of one but not the other. That being said, LDL-C is still a useful indicator for future cardiovascular illness and ideally you want to have both low LDL-C and LDL-P. (Click here to find optimal ranges for LDL-C and here for LDL-P)
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. 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.
Seyfried agrees that there is clear evidence that cancer is a genetic disease, since we can inherit mutations that are clearly associated with increased cancer risk. That’s not at all controversial. That’s well established, and even Seyfried agrees with that. But he argues that many of these mutations that we can inherit are mutations that actually disturb cellular respiration, maybe that the heritable aspect of cancer is not mutation that drives itself—cellular proliferation—but instead are mutations that actually cause mitochondrial dysfunction and defects in cellular respiration. He also points out that many of the non-inherited causes of cancer that have been identified and are clearly recognized, like radiation, impair mitochondrial function. That may be a common mechanism that is shared between these non-inherited causes of cancer and inherited causes of cancer.

People use a ketogenic diet most often to lose weight, but it can help manage certain medical conditions, like epilepsy, too. It also may help people with heart disease, certain brain diseases, and even acne, but there needs to be more research in those areas. Talk with your doctor first to find out if it’s safe for you to try a ketogenic diet, especially if you have type 1 diabetes.
From my extended research, non mammal ketogenic diet plus a high volume of carrot juice (slow juicer), paw paw fruit, piperine, matcha, turmeric can kill cancer really effectively. Problem is also that phytic acid foods have abscic? Acid that damages mitochondria as written in Japanese research journals. Does it mean that nuts, seeds, are nono? Hmm. Mammalian meat and dairy has neu5gc which is very toxic for us. Cancer is evolution trying to protect us from intense toxicity. Aldehyde from cooked polyunsaturated fat is also very toxic to us. Ex. Potato chips, potato fries
Now a report, appearing several weeks ago in the journal Neurology, reveals that in fact, a ketogenic diet is also profoundly helpful in adults as well in terms of treating epilepsy. This research, published by investigators in Maryland, found that there was at least a 50% reduction in seizures in 32% of patients treated with a ketogenic diet as well as in 29% of patients who went on a modified Atkins diet. In fact, 9% of those placed on the ketogenic diet and 5% of those placed on the modified Atkins diet had a greater than 90% reduction in the frequency of their epileptic seizures. These diets were designed such that the bulk of calories, between 67% and 75%, came from fat. The study revealed that “the anticonvulsant effect occurs quickly with both diets, within days to weeks.” Interestingly, the most common side effect was weight-loss which the office indicated “maybe advantageous inpatients with obesity.”
Now that we have discussed the role of the primary cholesterol molecules, you should have a better understanding of how they work together. Having high LDL isn’t necessarily bad, given that you have adequate HDL to help clear it from the blood stream and that you are not dealing with chronic inflammation. It is also important to have large particle LDL (pattern A) rather than small particle LDL (pattern B).
You’re very welcome, Judy! I’m glad it’s helpful. If you are keto (as opposed to low carb), unfortunately peaches would not allow you to stay in ketosis. You can check my keto food list to help determine what is keto friendly. Of course, there are worse things than fresh fruit 🙂 but in the end our bodies still see the sugar. That being said, it doesn’t mean you sabotaged the whole day. Just pick up again – you got this!! (And for next time, try some fresh berries in moderation when you’re craving fruit.)
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.
The ketogenic diet is usually initiated in combination with the patient's existing anticonvulsant regimen, though patients may be weaned off anticonvulsants if the diet is successful. Some evidence of synergistic benefits is seen when the diet is combined with the vagus nerve stimulator or with the drug zonisamide, and that the diet may be less successful in children receiving phenobarbital.
Another epilepsy syndrome in which the diet may be particularly useful is Dravet syndrome (also known as severe myoclonic epilepsy of infancy). This syndrome is classically described as a prolonged febrile seizure in the first 2 years of life, followed by focal-onset seizures, myoclonus, and developmental delays [16, Class III]. Dravet syndrome is associated in many cases with mutations in the gene SCN1A, a subunit of the sodium channel .
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.
Another study from 2014 suggests that the ketogenic diet is a safe, effective treatment to manage aggressive cancers when used with conventional therapies. For their retrospective study, researchers reviewed 53 patients with glioma, a tumor that starts in glial cells in the brain and spinal cord. These patients were treated with chemoradiotherapy and other standard treatments from August 2010 to August 2013. Six of these patients also consumed a ketogenic diet while on treatment.
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
With this rationale, VanItallie et al. [39, Class III] performed a feasibility study with PD patients and the ketogenic diet. They explored whether PD patients would be able to prepare the ketogenic diet in their homes and remain on it for at least 1 month. Of seven patients enrolled, five completed the study. They were monitored for ketone levels and weekly Unified Parkinson Disease Rating Scale (UPDRS) scores. All the patients lost weight. Interestingly, the mean decrease in UPDRS scores was 43.4%. A placebo effect is not ruled out, but this result at least suggests that the ketogenic diet was not harmful and certainly invites further study into its role in preserving neuron function in PD and other neurodegenerative diseases. The possibility that the diet may have altered levodopa absorption (and that this factor, rather than an effect of the diet on neuronal function, was responsible for the change) has not been studied rigorously .
