The ketogenic diet is a high-fat, adequate-protein, low-carbohydrate diet that is used primarily in the treatment of epilepsy in children. The diet forces the body to burn fats rather than carbohydrates. Normally, carbohydrates are contained in food glucose, which is then transported around the body and is particularly important in fueling brain function. However, if there is little carbohydrate in the diet, the liver converts fat into fatty acids and ketone bodies. The ketone bodies pass into the brain and replace glucose as an energy source. An elevated level of ketone bodies in the blood, a state known as ketosis, leads to a reduction in the frequency of epileptic seizures. Almost half of children, and young people, with epilepsy who have had some experience in this area, and the effect persists after discontinuing the diet. There is some evidence that the diet may be more effective, and that the strict regimen, such as modified diet, is similarly effective. The most common adverse effect is constipation, affecting about 30% of patients, which has been reduced to less than one year. The original therapeutic diet for pediatric epilepsy provides just enough protein for body growth and repair, and sufficient calories to maintain the correct weight for age and height. The classic therapeutic ketogenic was developed for the treatment of pediatric epilepsy in the 1920s and was widely used in the next decade, but its popularity with the introduction of effective anticonvulsant medications. This classic ketogenic diet contains a 4: 1 ratio by weight of fat to combined protein and carbohydrate. This is achieved by excluding high-carbohydrate starchy foods such as starchy, bread, pasta, grains and sugar, while increasing the consumption of high-fat nuts, cream, and butter. Most dietary fat is made of molecules called long-chain triglycerides (LCTs). However, medium-chain triglycerides (MCTs) -made of fatty acids with shorter carbon chains than LCTs-are more ketogenic. A variant of the classic diet known as MCT ketogenic diet uses a form of coconut oil, which is rich in MCTs, to provide around half the calories. A larger proportion of carbohydrate and protein can be consumed, allowing a greater variety of food choices. In the mid-1990s, Hollywood producer Jim Abrahams, whose son’s severe epilepsy was successfully controlled by the diet, created the Charlie Foundation to promote it. Publicity included an appearance on NBC’s Dateline program and … First Do No Harm (1997), made-for-television movie starring Meryl Streep. The foundation is a multicenter research study, the results of which-announced in 1996-marked the beginning of renewed scientific interest in the diet. Possible therapeutic uses for the ketogenic diet have been studied for various neurological disorders in addition to epilepsy: Alzheimer’s
Epilepsy is one of the most common neurological disorders after stroke, and affects at least 50 million people worldwide. It is diagnosed in a person having recurrent unprovoked seizures. These occur when cortical neurons fire excessively, hypersynchronously, or both, leading to temporary disruption of normal brain function. This might affect, for example, the muscles, the senses, consciousness, or a combination. A seizure can be focal (confined to one part of the brain) or generalised (spread widely throughout the brain and leading to a loss of consciousness). Epilepsy may occur for a variety of reasons; syndromes, most of which begin in childhood. Epilepsy is considered refractory (not yielding to treatment) when two or three anticonvulsant drugs have failed to control it. About 60% of patients will be treated with their first drug, compared to 30% of not control with drugs. When drugs fail, other options include epilepsy surgery, vagus nerve stimulation, and the ketogenic diet.
The ketogenic diet is a mainstream dietary therapy that has been developed to reproduce the success and the limitations of non-mainstream use of fasting to treat epilepsy. Although popular in the 1920s and 30s, it was widely abandoned in favor of new anticonvulsant drugs. Most patients with epilepsy can successfully control their seizures with medication. However, 20-30% fail to achieve such control despite a number of different drugs. For this group, and for children in particular, the diet has been found again in epilepsy management.
Physicians of ancient Greece related diseases, including epilepsy, by altering their patients’ diet. An early treatise in the Hippocratic Corpus, On the Sacred Disease, covers the disease; it dates from. It is proposed that the disease is supernatural in origin and has a rational and physical basis. In the same collection, the author of Epidemics describes the case of a man whose epilepsy is as soon as possible, through complete abstinence from food and drink. The Royal Physician Erasistratus declared, “One inclining to epilepsy should be made to fast without mercy and be put on short rations.” Galen believed an “attenuating diet” might afford a cure in mild cases and be helpful in others. The first modern study of fasting as a treatment for epilepsy was in France in 1911. Twenty epilepsy patients were all “detoxified” by consuming a low-calorie vegetarian diet, combined with periods of fasting and purging. Two benefited enormously, but most failed to maintain compliance with the restrictions. The diet improves patients’ mental capabilities, in contrast to their medication, bromide potassium, which dulled the mind. Around this time, Bernarr Macfadden, an American exponent of physical culture, popularized the use of fasting to restore health. His disciple, the physician osteopathic Hugh Conklin, of Battle Creek, MI, began to treat his patients by recommending fasting. Conklin conjectured that epileptic seizures were caused when a toxin, secreted from the Peyer ‘ s patches in the intestines, was discharged into the bloodstream. He recommended a fast lasting 18 to 25 days to allow this toxin to dissipate. Conklin probably treated hundreds of epilepsy patients with his “water diet” and boasted of a 90% cure rate in children, falling to 50% in adults. Conklin’s case records showed 20% of his patients achieved freedom from seizures and 50% had some improvement. Conklin’s fasting therapy has been adopted by neurologists in mainstream practice. In 1916, Dr. McMurray wrote to the New York Medical Journal claiming to have successfully treated patients with a fast, followed by a starch-and-sugar diet, since 1912. In 1921, prominent endocrinologist H. Rawle Geyelin reported his experiences to the American Medical Association convention. He had seen Conklin ‘ s success first-hand and had attempted to reproduce the results in 36 of his own patients. He achieved similar results despite having studied patients for a short time. Further studies in the 1920s indicated that they are generally returned after the fast. Charles Howland, Conklin’s successful patients and a wealthy New York corporate lawyer, gave his brother John a gift of $ 5,000 to study “the ketosis of starvation”. As professor of paediatrics at Johns Hopkins Hospital, John Howland used the money to fund research by Stanley Cobb and his assistant William G. Lennox.

In 1921, Rollin Woodyatt reviewed the research on diet and diabetes. He reported that three water-soluble compounds, β-hydroxybutyrate, acetoacetate and acetone (known collectively as ketone bodies), were produced when they were starved or if they consumed a very low-carbohydrate, high-fat diet. Russel Wilder, at the Mayo Clinic, which is a ketogenic diet to describe ketosis in the blood (ketonemia) through an excess of fat and lack of carbohydrate. Wilder hoped to obtain the benefits of a dietary therapy that could be maintained indefinitely. His trial on a few epilepsy patients in 1921 was the first use of the ketogenic diet as a treatment for epilepsy. Wilder’s colleague, pediatrician Mynie Peterman, Formulated the classic diet, with a ratio of one gram of protein per kilogram of body weight, 10-15 g of carbohydrate per day, and the remainder of calories from fat. Peterman’s work in the 1920s established the techniques for induction and maintenance of the diet. Peterman: positive effects (improved alertness, behavior and sleep) and adverse effects (nausea and vomiting due to excess ketosis). Peterman reported in 1925 that 95% of 37 young patients had had seizure control and 60% became seizure-free. By 1930, the diet had been studied in 100 teenagers and adults. Clifford Barborka, also from the Mayo Clinic, reported that 56% of those older patients improved on the diet and 12% became seizure-free. Although the results are similar to modern studies of children, they do not compare to contemporary studies. Barborka concluded that adults were less likely to benefit from diet, and the use of ketogenic diet in adults was not studied again until 1999.
During the 1920s and 1930s, when the only anticonvulsant drugs were sedative bromide (discovered 1857) and phenobarbital (1912), the ketogenic diet was widely used and studied. This changed in 1938 when H. Houston Merritt and Tracy Putnam discovered phenytoin (Dilantin), and the focus of research shifted to discovering new drugs. With the introduction of sodium valproate in the 1970s, drugs were available to neurologists that were effective across a broad range of epileptic syndromes and seizure types. The use of the ketogenic diet, by Lennox-Gastaut syndrome, declined further.
In the 1960s, it was discovered that medium-chain triglycerides (MCTs) produce more ketone bodies per unit of energy than normal dietary fats (which are mostly long-chain triglycerides). MCTs are more efficiently absorbed by the portal system rather than the lymphatic system. The severe carbohydrate restrictions of the ketogenic diet made it difficult for parents to produce palatable meals that their children would tolerate. In 1971, Peter Huttenlocher devised a ketogenic diet where about 60% of the calories came from the MCT oil, and this is more of a ketogenic diet. The oil is mixed with at least two of its volume of skimmed milk, chilled, and sipped during the meal or incorporated into food. He tested it on twelve children and adolescents with intractable seizures. Most children in seizure control and alertness, results that were similar to the classic ketogenic diet. Gastrointestinal upset was a problem, which was one of the patients to abandon the diet, but meals were easier to prepare and better accepted by the children. The MCT diet replaced the classic ketogenic diet in many hospitals, though some devised diets were a combination of the two.
The ketogenic diet achieved in the US in October 1994, when the NBC’s Dateline television program reported the case of Charlie Abrahams, the Hollywood producer Jim Abrahams. The two-year-old suffered from epilepsy that had remained uncontrolled by mainstream and alternative therapies. Charlie to John Freeman at Johns Hopkins Hospital, where he went to the therapy. Under the diet, Charlie’s epilepsy was rapidly controlled and his developmental progress resumed. This inspired Abrahams to create the Charlie Foundation to promote the diet and fund research. A multicenter prospective study began in 1994, the results were presented to the American Epilepsy Society in 1996 and were published in 1998. There followed an explosion of scientific interest in the diet. In 1997, Abrahams produced a TV movie, … First Do No Harm, starring Meryl Streep, in which a young boy’s intractable epilepsy is successfully treated by the ketogenic diet. By 2007, the ketogenic diet was available from around 75 centers in 45 countries, and the least restrictive variants, such as the modified atkins diet, were in use, particularly among older children and adults. The ketogenic diet was also under investigation for the treatment of a wide variety of disorders other than epilepsy. the ketogenic diet was available from around 75 centers in 45 countries, and less restrictive variants, such as the modified Atkins diet, were in use, particularly among older children and adults.

The ketogenic diet reduces seizure frequency by more than 50% in half of the patients who try it and by more than 90% in a third of patients. Three-quarters of children who do so within two weeks, though experts recommend a trial of at least three months before assuming it has been ineffective. Children with refractory epilepsy are more likely to benefit from the ketogenic diet than from trying another anticonvulsant drug. There is some evidence that adolescents and adults can also benefit from the diet.
Early studies reported that in one study in 1925, 60% of patients became seizure-free, and another 35% of patients had a 50% reduction in seizure frequency. These studies were generally reviewed by patients who were successfully treated with dietary restrictions. However, these studies are difficult to compare to modern trials. One reason is that these older trials were selected because they excluded patients who were unable to start or maintain their diet. In an attempt to control this bias, A prospective cohort is a prospective cohort in which the results are presented for all patients regardless of whether they are known to be treated or treated. 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 can be assumed to more difficult-to-treat epilepsy. Early and modern studies also differ because of 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 the health and growth of the diet’s restrictions. Fluid restriction was once more a feature of the diet, but it was not a beneficial effect.
A study with an intention-to-treat prospective design was published in 1998 by Johns Hopkins Hospital and followed by a report published in 2001. who did not receive treatment). The study enrolled 150 children. After three months, 83% of them were still on the diet, 26% had a good feeling, 31% had had a good time. At 12 months, 55% were still on the diet, 23% had a good response, 20% had an excellent response and 7% were seizure-free. Those who had discontinued the diet by this stage were so ineffective, too restrictive or due to illness, and most of those who were benefiting from it. The percentage of those still on the diet at three and four years was 39%, 20% and 12% respectively. During this period, the most common reason for discontinuing the diet was because the children had become seizure-free or significantly better. At four years, 16% of the original 150 children had a good history, but they were not so great, but they were not longer in the diet. Those remaining on the diet after this time were typically not-good-had-it-not-good. It is possible to combine the results of several studies with a single method of meta-analysis. One of four such analyzes, conducted in 2006, looked at 19 studies on a total of 1,084 patients. It concluded that a third success was achieved in patients suffering from a good reduction. A systematic review in 2016 found and analyzed seven randomized controlled trials of ketogenic diet in children and young people with epilepsy. The trials have been conducted among children and young people for whom they have failed to control their seizures. The other trials compared types of diets or ways of making them more tolerable. Nearly 40% of the children and young people had half or less seizures with the diet compared to the group not assigned to the diet. Only about 10% were still on the diet after a few years. Adverse effects such as hunger and loss of energy with about 30% experiencing constipation. A systematic review in 2018 reviewed at sixteen studies on the ketogenic diet in adults. It concluded that the treatment was becoming more popular for that group of patients, that the efficacy in adults was similar to children, the side effects relatively mild. However, many patients get up with the diet, for various reasons, and the quality of evidence inferior to studies on children. Health issues include high levels of low-density lipoprotein (LDL), high total cholesterol, and weight loss.

The ketogenic diet is indicated as an adjunctive (additional) treatment in children and young people with drug-resistant epilepsy. It is approved by national clinical guidelines in Scotland, England and Wales and by all US insurance companies. Children with a focal lesion (a single point in the diagnosis of epilepsy) who would make it easier to become infected with the ketogenic diet. About a third of epilepsy centers that offer the ketogenic diet also a dietary therapy to adults. Some clinicians consider the two less restrictive dietary variants-the low glycaemic index treatment and the modified Atkins diet-to be more appropriate for adolescents and adults. A liquid form of the ketogenic diet is particularly easy to prepare for, and well tolerated by, infants on formula and children who are tube-fed. Advocates for the diet recommend that it be seriously considered after two medications have failed, as the chance of other drugs succeeding is only 10%. The diet can be considered for some epilepsy and genetic syndromes where it has shown particular usefulness. These include Dravet syndrome, infant spasms, myoclonic-astatic epilepsy and tuberous sclerosis complex. A survey in 2005 of 88 pediatric neurologists in the US 24% of times prescribed the diet as a last resort; 24% had only prescribed the diet in a few rare cases; and 16% had never prescribed the diet. There are several possible explanations for this gap between evidence and clinical practice. One major factor may be the lack of adequately trained dietitians, who are required to administer a ketogenic diet program. Because the ketogenic diet alters the body’s metabolism, it is a first-line therapy in children with certain congenital metabolic diseases such as pyruvate dehydrogenase (E1) deficiency and glucose transporter 1 deficiency syndrome, which prevent the body from using carbohydrates as fuel, leading to a dependency on ketone bodies. The ketogenic diet is beneficial in the treatment of seizures and some other symptoms and is an absolute indication. On the other hand, it is absolutely contraindicated in the treatment of other diseases such as pyruvate carboxylase deficiency, porphyria and other rare genetic disorders of fat metabolism. A person with a disorder of fatty acid oxidation is unable to metabolize fatty acids, which replaces carbohydrates as the major energy source on the diet. On the ketogenic diet, their body would consume its own protein stores for fuel, leading to ketoacidosis, and eventually coma and death.
The ketogenic diet is usually initiated in the patient’s existing anticonvulsant regimen, though patients may be weaned off anticonvulsants if the diet is successful. There is some evidence of synergistic benefits when the diet is combined with the vagus nerve stimulator or with the zonisamide drug, and that the diet may be successful in receiving phenobarbital.
The ketogenic diet is not a benign, holistic or natural treatment for epilepsy; With any serious medical therapy, there may be complications. These are less severe than anticonvulsant medication or surgery. Commonly, this is a low-grade, low-grade acidosis and hypoglycaemia. Raised levels of lipids in the blood affect up to 60% of children and cholesterol levels may increase by around 30%. This article is available from the following links: http://www.youtube.com/watch?v=gbbbbbbbbbbbbb Supplements are necessary to counter the dietary deficiency of many micronutrients. Long-term use of the ketogenic diet in children increases the risk of slow or stunted growth, bone fractures and kidney stones. The diet reduces levels of insulin-like growth factor 1, which is important for childhood growth. Like many anticonvulsant drugs, the ketogenic diet has an adverse effect on bone health. Many factors may be involved as acidosis and suppressed growth hormone. About 1 in 20 children on the ketogenic diet will develop kidney stones (compared with one in several thousand for the general population). A class of anticonvulsants known as carbonic anhydrase inhibitors (topiramate, zonisamide) are known to increase the risk of kidney stones, but the combination of these anticonvulsants and the ketogenic diet does not appear to increase the risk of that diet alone. The stones are treatable and do not justify discontinuation of the diet. Johns Hopkins Hospital now offers oral potassium supplements to all ketogenic diet patients, resulting in a sevenfold decrease in the incidence of kidney stones. However, this empirical use has not been tested in a prospective controlled trial. Kidney stone formation (nephrolithiasis) is associated with the diet for four reasons:
The ketogenic diet is a medical nutrition therapy that involves participants from various disciplines. Team members include a registered pediatric dietitian who coordinates the diet program; a paediatric neurologist who is experienced in offering the ketogenic diet; and a registered nurse who is familiar with childhood epilepsy. Additional help may come from a medical professional who works with the family and a pharmacist who can advise on the carbohydrate content of medicines. Lastly, the parents and other caregivers must be educated in many aspects of the diet for it to be safely implemented. Implementing the diet can present difficulties for the caregivers and the patient. Since any unplanned eating can potentially break the nutritional balance required, some people find the discipline to keep the diet challenging and unpleasant. Some people end up at the diet, like the modified Atkins diet (MAD) or the low-glycaemic index treatment (LGIT) diet, because they find the difficulties too great.
The Johns Hopkins Hospital Protocol for initiating the ketogenic diet has been widely adopted. It involves the patient and their caregivers and later, a short hospital admission. Because of the risk of complications during ketogenic diet initiation, most centers. At the initial consultation, patients are screened for conditions that may constrain the diet. A dietary history is obtained and the parameters of the diet are adjusted to the ratio of fat to combined protein and carbohydrate, the calorie requirements and the fluid intake. The day before admission to hospital, the proportion of carbohydrate in the diet can be decreased and the patient begins fasting after his or her evening meal. On admission, only calorie- and caffeine-free fluids are restricted to one of the typical calories for a meal. The following breakfast and lunch are similar, and the “day” is a typical evening meal of caloric content. By the third day, dinner contains the full calorie quota and is a standard ketogenic meal (not “eggnog”). After a ketogenic breakfast on the fourth day, the patient is discharged. Where possible, the patient’s current medicines are changed to carbohydrate-free formulations. When in the hospital, glucose levels are monitored several times daily and are monitored for signs of symptomatic ketosis (which can be treated with a small amount of orange juice). Lack of energy and lethargy are common but disappear within two weeks. The parents attend classes, which covers nutrition, managing the diet, preparing meals, and avoiding sugar and handling illness. The level of parental education and commitment is higher than with medication. Variations on the John Hopkins protocol are common. The initiation can be performed outpatient clinics rather than requiring a stay in hospital. There is no initial fast (fasting increases the risk of acidosis and hypoglycaemia and weight loss). Rather than increase meal intake, some institutions maintain meal size but change the ketogenic ratio from 2: 1 to 4: 1. For patients who benefit, half achieve a reduction in five days (if the diet starts with an initial fast of one to two days), three-quarters achieve a reduction within two weeks, and 90% achieve a reduction within 23 days. If the diet does not begin with a fast, the time for the patients to achieve an improvement is longer (2 weeks). Parents are encouraged to persist with the diet for at least three months before being considered.
After initiation, the child usually visits the hospital where he or she is seen by the dietitian and neurologist, and various tests and examinations are performed. These are held every six months thereafter. Infants under one year old are seen more frequently, with the initial visit just after two to four weeks. A period of minor adjustments is ensured that the patient is more likely to be satisfied with the patient’s plans. This fine-tuning is typically done over the phone with the hospital dietitian and includes changing calories, altering the ketogenic ratio, or adding some MCT or coconut oils to a classic diet. Urinary ketone levels are checked daily to detect whether or not the patient is following the diet, although it does not correlate with an anticonvulsant effect. This is performed using nitroprusside containing nitroprusside test strips, which change color from buff-pink to maroon in the presence of acetoacetate (one of the three ketone bodies). A short-lived increase in seizure frequency may occur during illness or fluctuate ketone levels. The diet may be modified if it remains high, or the child is losing weight. Loss of seizure-control may come from unexpected sources. Even “sugar-free” can contain carbohydrates such as maltodextrin, sorbitol, starch and fructose.
About 20% of children on the ketogenic diet, and many are able to reduce the use of anticonvulsant drugs or altogether. Commonly, at around two years on the diet, or after six months of being seizure-free, the diet may be discontinued over two or three months. This is done by lowering the ketogenic rate until then, and then lifting all calorie restrictions. This timing and method of discontinuation of anticonvulsant drug therapy in children, where the child has become seizure free. When the diet is required to treat certain metabolic diseases, the duration will be longer. The total diet duration is up to the treatment ketogenic diet team and parents; durations up to 12 years have been studied and found beneficial. Children who discontinue the diet after achieving seizure freedom. The length of time until recurrence is highly variable but two years. This risk of recurrence is compared with 10% for resective surgery and 30-50% for anticonvulsant therapy. Of those that have a recurrence, just over half can regain freedom from seizures with anticonvulsants or by returning to the ketogenic diet. Recurrence is more likely if, despite seizure freedom, an electroencephalogram (EEG) shows epileptiform spikes, which indicate epileptic activity in the brain but are below the level that will cause a seizure. Recurrence is also possible if MRI scan shows focal abnormalities (for example, as in children with tuberous sclerosis).
The ketogenic diet is calculated by a dietitian for each child. Age, weight, activity levels, culture and food. First, the energy requirements are set at 80-90% of the recommended daily amounts (RDA) for the child’s age (the high-fat diet requires less energy to process than a typical high-carbohydrate diet). Highly active children or those with muscle spasticity require more calories than this; still children require less. The ketogenic ratio of diet compared to the weight of fat to the weight of carbohydrate and protein. This is typically 4: 1, but children who are younger than 18 months, older than 12 years, or who are obese may be started on a 3: 1 ratio. Fat is energy-rich, with 9 kcal / g (38 kJ / g) compared to 4 kcal / g (17 kJ / g) for carbohydrate or protein, so the ketogenic diet is smaller than normal. The quantity of fat in the diet can be calculated from the overall energy requirements and the chosen ketogenic ratio. Next, the protein levels are set to allow for growth and body maintenance, and are around 1 g protein for each kg of body weight. Lastly, the amount of carbohydrate is set according to what is left over while maintaining the chosen ratio. Any carbohydrate in medications or supplements should be subtracted from this allowance. The total daily amount of fat, protein and carbohydrate is then evenly divided across the meals. KetoCalculator can be used to help generate recipes. The meals often have four components: heavy whipping cream, a protein-rich food (typically meat), a fruit or vegetable and a fat such as butter, vegetable oil or mayonnaise. Only low-carbohydrate fruits and vegetables are allowed, which excludes bananas, potatoes, peas and corn. Suitable fruits are divided into two groups based on the amount of carbohydrate they contain, and are similarly divided into two groups. Foods within each of these four groups may be freely substituted for recalculated portion sizes. For example, cooked broccoli, sprouts, cauliflower and green beans are all equivalent. Fresh, canned or frozen foods are an additional complication. Parents are required to be accurate when measuring food quantities on an electronic scale accurate to 1 g. The child must eat the whole meal and can not have extra portions; any snacks must be incorporated into the meal plan. A small amount of MCT can be used to help with constipation or to increase ketosis. The classic ketogenic diet is a balanced diet and contains tiny portions of fresh fruit and vegetables, fortified cereals and calcium-rich foods. In particular, vitamin B, calcium and vitamin D must be artificially supplemented. This is achieved by taking two sugar-free supplements for the patient’s age. A typical day of food for a child has a 4: 1 ratio, 1,500 kcal (6,300 kJ) including ketogenic diet. : calcium and vitamin D must be artificially supplemented.

Normal dietary fat with mostly long-chain triglycerides (LCT). Medium-chain triglycerides are more ketogenic than LCTs because they generate more ketones per unit of energy when metabolized. Their use permits a greater proportion of fat and a greater proportion of protein and carbohydrate, leading to more food choices and larger sizes. The original MCT diet developed by Peter Huttenlocher in the 1970s derived 60% of its calories from MCT oil. Consuming that amount of MCT caused by abdominal cramps, diarrhea and vomiting in some children. A figure of 45% is regarded as a balance between achieving good ketosis and minimizing 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 is more expensive than other dietary fats and is not covered by insurance companies.
First reported in 2003, the idea of using an atkins diet to treat epilepsy has been reported in the past. The ketogenic diet team at Johns Hopkins Hospital has modified the inducing effect of inducing indefinitely, inducing and inducing fat loss. Compared with the ketogenic diet, the modified Atkins diet (MAD) places no limit on calories or protein, and the overall overall ketogenic ratio (approximately 1: 1) does not need to be maintained by all meals of the day. The MAD does not begin with a diet, nor does it require a dietitian support than the ketogenic diet. Carbohydrates are initially limited to 10 g per day in children or 20 g per day in adults, and are increased to 20-30 g per day after a month or so, depending on the effect of control or tolerance of the restrictions. Like the ketogenic diet, the MAD requires vitamins and minerals to be carefully and periodically monitored at outpatient clinics. The modified Atkins diet reduces seizure frequency by 50% in 43% of patients who try it by 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, these results from 2009 compare favorably with the traditional ketogenic diet.

The low glycaemic index treatment (LGIT) is an attempt to achieve stable blood glucose levels in the dietetic ketogenic diet while using a much less restrictive regimen. The hypothesis is that stable blood glucose may be one of the mechanisms of action involved in the ketogenic diet, which is caused by the absorption of limited carbohydrates. Although it is also a high-fat diet (with approximately 60% calories from fat), the LGIT allows more carbohydrate than either the classic ketogenic diet or the modified Atkins diet, approximately 40-60 g per day. However, the types of carbohydrates consumed are smaller than 50. Like the modified Atkins diet, the LGIT is a fully-funded and well-established dietitian. Both are more likely than others to have ketogenic diet programs, and they are often the primary dietary therapy for adolescents. Short-term results for the LGIT indicates that it is one of the largest patients in the world. The data (coming from one of the world’s largest families of young children) is also more important than any other diet. and in some centers they are often the primary dietary therapy for adolescents.

Infants and patients fed via a gastrostomy tube can also be given a ketogenic diet. Parents make up a prescribed powdered formula, such as KetoCal, into a liquid feed. Gastrostomy feeding avoids any issues with palatability, and bottle-fed infants readily accepts the ketogenic formula. Some studies have found this fluid to be more effective and associated with lower total cholesterol than a solid ketogenic diet. KetoCal is a nutritionally complete food containing milk protein and is supplemented with amino acids, fat, carbohydrate, vitamins, minerals and trace elements. It is used to administer the 4: 1 ratio of classic ketogenic diet in children over one year. The formula is available in both 3: 1 and 4: 1 ratios, either unflavoured or artificially sweetened vanilla flavor and is suitable for tube or oral feeding. Other formulas include KetoVolve and Ketonia. Alternatively, a liquid ketogenic diet can be produced by the combination of Ross Carbohydrate Free formula with Microlipid and Polycose.
There are theoretical restrictions on the ketogenic diet that can be used, and it can cost less than modern anticonvulsants. However, fasting and dietary changes are affected by religious and cultural issues. A culture where food is often prepared by grandparents or hired help means more people must be educated about the diet. When families dine together, sharing the same meal, it can be difficult to separate the child’s meal. In many countries, food labeling is not mandatory so calculating the proportions of fat, protein and carbohydrate is difficult. In some countries, it can be used to obtain accurate, accurate, or inexpensive MCT oils. In Asia, the natural diet includes rice and noodles as the main source of energy, making their elimination difficult. Therefore, the MCT-oil form of the diet, which allows more carbohydrate, has proved useful. In India, religious beliefs commonly affect the diet: some patients are vegetarians, will not eat root vegetables or avoid beef. The Indian ketogenic diet is started without a fast as opposed to fasting in children. The low-fat, high-carbohydrate nature of the normal Indian and Asian diet means that their ketogenic diets typically have a lower ketogenic ratio (1: 1) than in America and Europe. However, they appear to be just as effective. In many developing countries, the ketogenic diet is more expensive than grain, fruit and vegetables. The modified Atkins diet has been proposed as a lower-cost alternative for those countries; the most expensive food bill can be offset by a reduction in pharmaceutical costs if the diet is successful. The modified Atkins diet is less complex and requires less support from a dietitian.
The brain is composed of a network of neurons that transmit signals by propagating nerve impulses. The propagation of this neuron is another neurotransmitters, although there are also electrical pathways between some neurons. Neurotransmitters can inhibit impulse firing (primarily caused by γ-aminobutyric acid, or GABA) or they can excite the neuron into firing (primarily done by glutamate). A neuron that releases inhibitory neurotransmitters from its terminals is called an inhibitory neuron, while one that excitatory excitatory neurotransmitters is an excitatory neuron. When the normal balance between inhibition and excitation is significantly disrupted in all or part of the brain, a seizure can occur. The GABA system is an important target for anticonvulsant drugs, can be discussed by increasing GABA synthesis, decreasing its breakdown, or enhancing its effect on neurons. The nerve impulse is characterized by a large influx of sodium ions through channels in the neuron’s cell membrane followed by an efflux of potassium ions through other channels. The neuron is unable to fire again for a short time (known as the refractory period), which is mediated by another potassium channel. The flow through these ions is governed by a “gate” which is opened by a voltage change or a chemical messenger known to a ligand (such as a neurotransmitter). These channels are another target for anticonvulsant drugs. There are many ways in which epilepsy occurs. Examples of pathological physiology include: unusual excitatory connections within the neuronal network of the brain; abnormal neuron structure leading to altered current flow; decreased inhibitory neurotransmitter synthesis; ineffective receptors for inhibitory neurotransmitters; excessive breakdown of excitatory neurotransmitters leading to excess; immature synapse development; and impaired function of ionic channels.
Although many hypotheses have been put forward to explain the ketogenic diet works, it remains a mystery. Disproven hypotheses include systemic acidosis (high levels of acid in the blood), electrolyte changes and hypoglycemia (low blood glucose). 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. On the ketogenic diet, carbohydrates are provided for the metabolic needs of the body. Instead, fatty acids are used as the major source of fuel. These are used through fatty acid oxidation in the cell’s mitochondria (the energy-producing parts of the cell). Humans can convert some amino acids into glucose by a process called gluconeogenesis, but can not do this by using fatty acids. Since amino acids are needed to make proteins, which are essential for growth and repair of body tissues, these can be used only to produce glucose. This problem has been posed for the brain, since it is normally fuelled solely by glucose, and most fatty acids do not cross the blood-brain barrier. However, the β-hydroxybutyrate, acetoacetate and acetone. These ketone bodies enter the brain and partially substitute for blood glucose as a source of energy. The ketone bodies are possibly anticonvulsant; in animal models, acetoacetate and acetone protect against seizures. The ketogenic diet results in adaptive changes to the brain energy metabolism that increases the energy reserves; ketone bodies are a more efficient fuel than glucose, and the number of mitochondria is increased. This may help the neurons to remain stable in the face of increased energy demand during seizure, and may confer a neuroprotective effect. The ketogenic diet has been studied in at least 14 years old animal models of seizures. It is protective in many ways and has a different protection than any known anticonvulsant. Conversely, fenofibrate, not used clinically as 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 a half dozen drugs, suggests a unique mechanism of action. Anticonvulsants suppress epileptic seizures, but they neither cure nor prevent the development of seizure susceptibility. The development of epilepsy (epileptogenesis) is a process that is poorly understood. A few anticonvulsants (valproate, levetiracetam and benzodiazepines) have shown antiepileptogenic properties in animal models of epileptogenesis. However, no anticonvulsant has ever achieved this in a clinical trial in humans. The ketogenic diet has been found to have antiepileptogenic properties in rats. levetiracetam and benzodiazepines) have shown antiepileptogenic properties in animal models of epileptogenesis.

The Alzheimer’s disease (AD), amyotrophic lateral sclerosis (ALS), autism, headache, neurotrauma, pain, Parkinson’s disease (PD) and sleep disorders. Because tumor cells are inefficient in treatment, the ketogenic diet has also been suggested for treatment for cancer. A 2018 review looked at the evidence of preclinical and clinical studies of ketogenic diets in cancer therapy. The clinical studies in humans are typically very small, with some providing weak evidence for anti-tumor effect, particularly for glioblastoma, but in other cancers and studies, no anti-tumor effect was seen. Taken together, results from preclinical studies, albeit sometimes contradictory, tends to support an anti-tumor effect rather than a pro-tumor effect of the KD for most solid cancers. The evidence of benefit for these conditions has not reached the level where clinical recommendations can be made.
