In this way, stem cells allow complex life to exist and continue, providing tissue replacements as needed, appropriate for the tissue in which they live. That is, liver stem cells will create new liver cells as needed, bone marrow stem cells will create new bone marrow clones as required, intestinal stem cells will form, as necessary, intestinal lining cells. In this way, the developmental capacity of stem cells seems to be governed by the local environment.
Apoptosis Induction. Studies show that dietary energy restriction enhances phosphorylation of adenosine monophosphate kinase (AMPK), which has been found to induce apoptosis in glycolytic-dependent brain cells and protect normal brain cells from death. One way to naturally restrict energy consumption is with a keto diet because most keto dieters spontaneously eat fewer calories than they do when they are on a higher carb diet. Altogether, this may explain why most of the research on keto and cancer has shown the keto diet to be effective in the treatment of brain tumors (glioblastomas and gliomas).
When in the hospital, glucose levels are checked several times daily and the patient is monitored for signs of symptomatic ketosis (which can be treated with a small quantity of orange juice). Lack of energy and lethargy are common, but disappear within two weeks. The parents attend classes over the first three full days, which cover nutrition, managing the diet, preparing meals, avoiding sugar, and handling illness. The level of parental education and commitment required is higher than with medication.
If your child is helped by the diet and seizures are better controlled, your child may remain on the ketogenic diet for 2 to 3 years, or longer. The length of time on the diet will be determined by several factors, including how well the diet helps your child, whether your child can be weaned off seizure medications, and your willingness to continue the diet.
Cancer cells are unlike normal cells in many ways, but one of their traits that is most unique regards insulin receptors. They have ten times more insulin receptors on their cellular surface. This enables cancer cells to gorge themselves in glucose and nutrients coming from the bloodstream at a very high rate. As you continue to consume glucose as your primary diet source, cancer cells will continue to thrive and spread. It is no surprise that the lowest survival rate in cancer patients is among those with the highest blood sugar levels.
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 . 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.
Cholesterol serves a number of important roles in the body. First of all, cholesterol is a critical structural element in certain tissues such as our brain and nervous system. In fact, it is estimated that around 25% of our cholesterol can be found in the brain. Just to highlight our failed fat philosophy over the years, higher saturated fat intake and high cholesterol levels are associated with better mental function in old age (1)!
So rather than giving one-size-fits-all dietary advice or weaponizing the word “balanced” it might be better if the medical community suggested that there are Individual differences that need to be considered. This might also help those lay folk who have had success with one dietary lifestyle or another also realize that what’s valid for them may not be good advice for others.
This was a great read. I aim to restrict carbs always because I believe most are why the American population is obese. I would very much like to hear more about carb restriction excluding the discussion on processed meats and processed high salt content foods because I consume neither. I also don’t consume dairy or eggs. So can you provide some substance.
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"
Over the past century, ketogenic diets have also been used as natural remedies to treat and even help reverse neurological disorders and cognitive impairments, including epilepsy, Alzheimer’s symptoms, manic depression and anxiety. Research shows that cutting off glucose levels with a very low-carb diet makes your body produce ketones for fuel. This change can help to reverse neurological disorders and cognitive impairment, including inducing seizure control. The brain is able to use this alternative source of energy instead of the cellular energy pathways that aren’t functioning normally in patients with brain disorders.
Eating a 5,000-calorie diet high in fat will certainly put you in ketosis, but you probably won’t lose weight because those excessive calories have to go somewhere. You needn’t be as adamant about calories doing a ketogenic diet, but they do still matter. Drizzling 500 calories of MCT oil or butter onto your steak will probably get you into ketosis, but the scales aren’t going to provide you much love. However, having the right amount of extra fat in the diet while keeping starchy carbohydrates low will make you into a fat-burning machine.
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 . 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 .
The modified Atkins diet reduces seizure frequency by more than 50% in 43% of patients who try it and by more than 90% in 27% of patients. Few adverse effects have been reported, though cholesterol is increased and the diet has not been studied long term. Although based on a smaller data set (126 adults and children from 11 studies over five centres), these results from 2009 compare favourably with the traditional ketogenic diet.
Although the ketogenic diet has been around for a long time and may be efficacious in many medical conditions, there is a surprising dearth of long-term studies on its safety. The bulk of the information comes from children using a ketogenic diet for epilepsy. Negative effects seen in children on a ketogenic diet long-term (≥2 years) are poor growth (while on the diet), kidney stones, and dyslipidemia (elevated cholesterol and/or triglycerides). Many of these effects can be overcome with careful attention to mineral intake while on the diet and/or termination of the diet.52 Most long-term studies evaluating adults using a ketogenic diet for weight loss have found very few serious adverse effects.53 54 55 56 However it should be noted that these studies only looked at one year duration on the diet, and poor adherence to the diet was frequently noted as a problem.
Kelsey: Hi, Chris, I was just wondering about your thoughts on the ketogenic diet as an approach to cancer prevention and therapy. I just read something about how cancer cells can only thrive on glucose, and in its absence we can prevent cancer potentially. So I was wondering if you could discuss this in a podcast. I think that would be great. Thank you.
[29:44] – There is increasing evidence for what Dave likes to call, the Alternative Glycogen Store Theory. Do leaner, athletic types of individuals seem to be more likely to be hyper-responders, in particular those with lower levels of triglycerides and high levels of LDL-C and LDL-P? Gary mentions Dr William Davis, from Wheat Belly, post on Lp(a) traits.
[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)
Drink lots of water. This is especially crucial on a low carb or keto diet. Why? When you eat carbohydrates, your body stores the extra as glycogen in the liver, where they are bound to water molecules. Eating low carb depletes this glycogen, which allows you to burn fat – but it also means you are storing less water, making it easier to get dehydrated. Instead of the traditional recommendation of 8 cups of water per day, aim for 16 cups when following a low carb lifestyle.
Aside from the various keto-friendly foods mentioned in this article, you may be wondering if there are other options that may help support your ketogenic diet. If you find that the ketogenic diet is limiting when you start out, don't worry. There's actually a lot you can add to your diet that's "keto" as long as consumption is controlled. Here are some commonly asked questions:
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.  In fact, one study observed that, with every 1 mg/dL reduction in HDL cholesterol, diabetes risk increased by 4%.

I won’t sugar coat it. The diet can be hard to start. The first two weeks can be terrible. You give up a lot of comfort foods. Plus, you will need new cookbooks. So, switching to a ketogenic diet isn’t the first thing that pops into your head when you hear cancer. But the diet works. I steadily lost weight without substantial hunger or changes to my limited exercise program. My overall health improved, I slept better, felt better and hopefully look better.
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.

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.)
As I wrote in my book, “Nevertheless on the therapy [Kelley’s] he slowly began to improve, to the point his mental status normalized and over a period of a year, he progressed from a wheelchair to a walker to a cane.” When I completed my study in 1987, he had survived 5 years and was in excellent health, with no evidence of cancer in his brain or spinal canal.
• Increasing muscle mass — Jeff Volek, Ph.D., is a registered dietitian specializing in how a high-fat, low-carb diet can affect health and athletic performance. He's written many scientific articles on this topic, as well as two books, and he explains that ketones have a similar structure to branched-chain amino acids that can be useful for building muscle mass. Ketones spare these amino acids, leaving higher levels of them around, which can help promote muscle mass.
At KetoPet, our mission is to help dogs everywhere live longer, happier lives by teaching pet parents how to feed a raw ketogenic diet. Based on our studies, we believe that a raw ketogenic diet for dogs is the optimal diet for dog health and longevity. Unfortunately, each year about 6 million dogs in the US alone will be diagnosed with cancer. We’re focused on changing those statistics by changing your dog’s diet.
Gluconeogenesis is the endogenous production of glucose in the body, especially in the liver primarily from lactic acid, glycerol, and the amino acids alanine and glutamine. When glucose availability drops further, the endogenous production of glucose is not able to keep up with the needs of the body and ketogenesis begins in order to provide an alternate source of energy in the form of ketone bodies. Ketone bodies replace glucose as a primary source of energy. During ketogenesis due to low blood glucose feedback, stimulus for insulin secretion is also low, which sharply reduces the stimulus for fat and glucose storage. Other hormonal changes may contribute to the increased breakdown of fats that result in fatty acids. Fatty acids are metabolized to acetoacetate which is later converted to beta-hydroxybutyrate and acetone. These are the basic ketone bodies that accumulate in the body as a ketogenic diet is sustained. This metabolic state is referred to as "nutritional ketosis." As long as the body is deprived of carbohydrates, metabolism remains in the ketotic state. The nutritional ketosis state is considered quite safe, as ketone bodies are produced in small concentrations without any alterations in blood pH. It greatly differs from ketoacidosis, a life-threatening condition where ketone bodies are produced in extremely larger concentrations, altering blood ph to acidotic a state.
• Reducing appetite — Constant hunger can cause you to consume more calories than you can burn, which can eventually lead to weight gain. A ketogenic diet can help you avoid this problem because reducing carbohydrate consumption can reduce hunger symptoms. In one study, participants who were given a low-carbohydrate diet had reduced appetites, helping them lose weight easier.2
Fanatic? Someone with T2D, a disease usually claimed to be progressive and a never ending stream of problems and medications, was REVERSED. That’s something to shout from the rooftops. The drop in medication use alone, but the big pharma companies would prefer that people’s stories of reversing (well, putting it into remission) T2D get called fanatical instead of insightful.
"Most of the work in this field is still pre-clinical, meaning it's been conducted in animal models," Angela Poff, a research associate in the Department of Molecular Pharmacology and Physiology at the University of South Florida, told U.S. News & World Report. "It's been done in various cancer types, but most of the work has been done in brain cancer specifically. But there's very little clinical data all around. There's some case reports and very small preliminary clinical studies in small groups of patients, usually very late-stage patients with various types of cancers. So in the clinical realm, which is the most important in telling us whether this is going to be useful, we have a long way to go."
Carbohydrates have been linked to this skin condition, so cutting down on them may help. And the drop in insulin that a ketogenic diet can trigger may also help stop acne breakouts. (Insulin can cause your body to make other hormones that bring on outbreaks.) Still, more research is needed to determine exactly how much effect, if any, the diet actually has on acne.
Another hypothesis regarding the function of the KD is related to changes in neuronal metabolism, mitochondrial function and energy reserve, and the environment. In normal conditions, the usual substrate for the neurons is glucose. To facilitate its diffusion through the brain-blood barrier, glucose transports are present in the brain capillary endothelial layer (Greene et al., 2003). The glucose metabolism produces the rapidly available energy that is necessary for seizure activity. Therefore, in patients on the KD, the blood glucose energy levels are low, and the brain begins to use KB for energy. This anaerobic metabolism slows the energy availability, which reduces seizures. The anticonvulsant propriety of a decrease in glucose metabolism has been shown in experimental models in which the administration of 2-Deoxy-D-glucose elevates the seizure threshold (Garriga-Canut et al., 2006). The anticonvulsant effect of the KD can be quickly reversed after glucose infusion (Huttenlocher, 1976). Based on these data, we can postulate the influences not only of the KB, as discussed above, but also the reduction in glucose levels as a mechanism of action of the KD.
Ketogenic diets represent a far more effective strategy for managing type 2 diabetes than the American Diabetes Association’s high-carb, low-fat dietary guidelines. Unlike the ADA’s guidelines, a ketogenic diet significantly reduces blood sugar, hemoglobin A1c levels, waist circumference, and triglycerides in diabetic individuals. (13) Most importantly, research indicates that the diet is sustainable for diabetic patients and that the beneficial changes can be maintained over the long term. (14)
In order to transition and remain in this state, aiming for about 30–50 net grams is typically the recommended amount of total carbs to start with. This is considered a more moderate or flexible approach but can be less overwhelming to begin with. Once you’re more accustomed to “eating keto,” you can choose to lower carbs even more if you’d like (perhaps only from time to time), down to about 20 grams of net carbs daily. This is considered the standard, “strict” amount that many keto dieters aim to adhere to for best results, but remember that everyone is a bit different.
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.
Sign up 24 hours before the general public and increase your chances of getting a spot. We only open the certification program twice per year. Due to high demand, spots in the program are limited and have historically sold out in a matter of hours. But when you sign up for the presale list, we’ll give you the opportunity to register a full 24 hours before anyone else.
If you need to eat more or fewer calories per day, you can adjust accordingly by simply taking out or adding a bit more of the ingredients already included in a recipe. For example, adding/removing a tablespoon of olive oil or butter will add/remove about 100 calories. If you like or dislike certain recipes, feel free to shift things around. Make sure to keep an eye on the calories so you’re still falling within an acceptable range of your daily goal.
Normally, our bodies run on energy from glucose, which we get from food. We can’t store large amounts of glucose, however. We only have about a 24-hour supply. When a child has no food for 24 hours — which is the way the diet begins, usually in a hospital — he or she uses up all the stored glucose. With no more glucose to provide energy, the child’s body begins to burn stored fat.
Diets aren’t just for weight loss. What, how much, and even when we eat all affect the way our brains work. For people with epilepsy, diet can reduce the likelihood of seizures. Mackenzie Cervenka, a neurologist and director of the Adult Epilepsy Diet Center at Johns Hopkins Hospital, explains what the ketogenic diet is and how it can benefit people with epilepsy.
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.
• 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
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).
Her agent, according to reports at the time, began circulating a book proposal the day after the Times story ran, asking for a $2 million dollar advance! The whole episode raised some eyebrows over a reporter seeking to benefit personally from a subject she was promoting in the news section of the Times. After a fair amount of criticism, Kolata withdrew her book proposal.
Dietary treatments for diseases have probably been used for over 2000 years (Yuen and Sander, 2014). Fasting is the only therapeutic measure against epilepsy recorded in the Hippocratic collection. Two Parisian physicians, G Guelpa, and A Marie, recorded the first modern use of starvation as a treatment for epilepsy in 1911 (Wheless, 2008). The modern use of this form of therapy began in the early 1920s (Lima et al., 2014; Yuen and Sander, 2014), when Drs. Stanley Cobb and W.G. Lennox of Harvard at Harvard Medical School observed the effects of starvation as a treatment for epilepsy, noting that seizure improvement typically occurred after 2–3 days (Wheless, 2008). In the same period, Dr. Russel M. Wilder a physician at the Mayo Clinic in Minnesota, suggested that a specific diet could produce similar benefits to fasting, and proposed a diet that produced ketonemia. He studied a series of patients with epilepsy and demonstrated a result equivalent to fasting and that was maintained for a much longer period. This new concept of diet was designated the “KD.” Peterman, also at the Mayo Clinic, described a composition of the KD similar to that used today (Wilder, 1921).
Fight Cancer with a Ketogenic Diet is not an academic exercise in what a ketogenic rendition of an anticancer diet should be. The information is firmly based on the science and research of Dr. Thomas Seyfried, who proposes that cancer is a metabolic disease, and on consultation with both Drs. Seyfried and Dominic D’Agostino on design and implementation of a ketogenic diet. Sound biochemical and physiological sciences support the book’s explanations and recommendations.
Stem cells, wherever they may be found, can adapt quite nicely, and are far more flexible than originally believed. In laboratory animals, a liver stem cell placed into the bone marrow starts creating not liver, but bone marrow cells, a bone marrow stem cell transplanted into the liver begins to generate not bone marrow, but liver cells. The environment appears to be the key, ultimately determining the direction of stem cell development.
Since my numbers were high my doc ordered a calcium scoring test which shows some mild calcium increase in my lower depending artery which is not normal for a female of my age and health. Initially he wanted me to abandon the diet and follow a Mediterranean low fat diet. I suggested I eat more monounsaturated fats but stay on the low carb diet and he agreed. I have seen a great deal of benefit from the low carb diet and am unwilling to give it up at this time.
In this article, I have presented a number of cases, seven to be exact, four from Kelley’s files and three from my own practice. The four Kelley cases include the 31-year survivor of metastatic pancreatic cancer confirmed at Mayo, the 34-year survivor of stage IV endometrial cancer, the five-year survivor of aggressive brain cancer, and the 11-year survivor of advanced, aggressive multiple myeloma.
To counteract these genetic vulnerabilities, it is may be best to eat a low to moderate fat diet that is whole food based with plenty of fiber, monounsaturated fats, polyunsaturated fats (especially omega 3s), and limited saturated fats. This, as well as a lifestyle filled with physical activity, stress relief practices, and plenty of sleep, should keep their cholesterol levels under control.
A lot of people take their macros as a “set in stone” type of thing. You shouldn’t worry about hitting the mark every single day to the dot. If you’re a few calories over some days, a few calories under on others – it’s fine. Everything will even itself out in the end. It’s all about a long term plan that can work for you, and not the other way around.
We decided to join a ketogenic diet study. Not something you would have expected for cancer treatment. This wasn’t a random decision because there are many studies looking at how diets might improve cancer outcomes. I joined Alina as a coach and chef. You probably have heard about the “ketogenic” diet. It consists of lots of fat, some protein, and minimal carbs. Using this diet, our body switches from glucose as a fuel source to ketones. Carbs are strictly for those must-have nutrients.
A study of 39 obese adults placed on a ketogenic very low-calorie diet for 8 weeks found a mean loss of 13% of their starting weight and significant reductions in fat mass, insulin levels, blood pressure, and waist and hip circumferences. Their levels of ghrelin did not increase while they were in ketosis, which contributed to a decreased appetite. However during the 2-week period when they came off the diet, ghrelin levels and urges to eat significantly increased. 
A: The amount of weight you lose is entirely dependent on you. Obviously adding exercise to your regimen will speed up your weight loss. Cutting out things that are common “stall” causes is also a good thing. Artificial sweeteners, dairy, wheat products and by-products (wheat gluten, wheat flours, and anything with an identifiable wheat product in it).
"The keto diet is primarily used to help reduce the frequency of epileptic seizures in children. While it also has been tried for weight loss, only short-term results have been studied, and the results have been mixed. We don't know if it works in the long term, nor whether it's safe," warns registered dietitian Kathy McManus, director of the Department of Nutrition at Harvard-affiliated Brigham and Women's Hospital.
In part, keto diet weight loss is a real thing because high-fat, low-carb diets can both help diminish hunger and boost weight loss through their hormonal effects. As described above, when we eat very little foods that supply us with carbohydrates, we release less insulin. With lower insulin levels, the body doesn’t store extra energy in the form of fat for later use, and instead is able to reach into existing fat stores for energy.
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.
Jimmy Moore: One year ago my, I guess this about a year and a half ago now, time flies when you’re having fun … my total cholesterol was over 400. A lot of people, and of course I talked to lipidologists and heart people all the time on my podcasts, and I was throwing the numbers out there and one of the lipidologists “Oh you need the highest dose of Staten drug possible because you’ll not be able to get that down without it.” In writing Cholesterol Clarity, I determined that I had some other things that were raising the cholesterol and it’s not that I have a Staten drug deficiency. It’s that I have something underlined inside of me somewhere that the cholesterol was going to try to take care of.
Some practitioners have raised the concern that long-term adherence to a ketogenic diet may shift the composition of the microbiota (the beneficial microbes that live in our bodies) in an undesirable direction and may even encourage the overgrowth of ‘bad’ bacteria. These beneficial bacteria feed on prebiotics (such as fiber and resistant starch), both of which are likely to be low in a low-carbohydrate ketogenic diet. Without prebiotics, beneficial bacteria are not able to produce substances like butyrate and other short chain fatty acids that keep the intestinal cells healthy, and long-term disruption of the microbiota can lead to a host of health problems throughout the body. 57 58
Normal dietary fat contains mostly long-chain triglycerides (LCTs). Medium-chain triglycerides (MCTs) are more ketogenic than LCTs because they generate more ketones per unit of energy when metabolised. Their use allows for a diet with a lower proportion of fat and a greater proportion of protein and carbohydrate, leading to more food choices and larger portion sizes. The original MCT diet developed by Peter Huttenlocher in the 1970s derived 60% of its calories from MCT oil. Consuming that quantity of MCT oil caused abdominal cramps, diarrhea, and vomiting in some children. A figure of 45% is regarded as a balance between achieving good ketosis and minimising gastrointestinal complaints. The classical and modified MCT ketogenic diets are equally effective and differences in tolerability are not statistically significant. The MCT diet is less popular in the United States; MCT oil is more expensive than other dietary fats and is not covered by insurance companies.
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).  Some studies show a strong correlation between LDL cholesterol and the risk of cardiovascular diseases in both men and women.  Evidence also suggests that decreasing blood levels of LDL-C reduces the risk of CVD.
