Keto Diet: Effective Treatment For Seizures?

The ketogenic diet is a special high-fat, low-carbohydrate diet that has been used to control seizures in people with epilepsy, especially those who don't respond to anti-seizure medications. The diet induces a metabolic state called ketosis, which is believed to reduce seizure frequency and severity. The diet is usually recommended for children with epilepsy and is carefully monitored by a physician and a dietitian. While the exact mechanism of how the ketogenic diet works is still not completely understood, several theories have been proposed, including an increase in ketones, an increase in energy production in the brain, and changes in the microbes found in the intestine.

Ketogenic diet and epilepsy

The ketogenic diet is a high-fat, low-carbohydrate diet that has been used to control seizures in people with epilepsy, especially children whose seizures have not responded to medication. The diet is usually prescribed by a physician and carefully monitored by a dietitian. The diet is stricter than the modified Atkins diet, requiring careful measurements of calories, fluids, and proteins. The diet produces ketones in the body, which are formed when the body uses fat for energy instead of carbohydrates. Ketones are not dangerous and can be detected in the urine, blood, and breath. Higher ketone levels often lead to improved seizure control.

The classic ketogenic diet is not usually recommended for adults due to its restricted food choices, but the modified Atkins diet is a viable option for adults and is done with a team of adult neurologists and dietitians. The ketogenic diet has been shown to be particularly helpful for some epilepsy conditions, including infantile spasms, Rett syndrome, tuberous sclerosis complex, Dravet syndrome, Doose syndrome, and GLUT-1 deficiency. The diet works well for children with focal seizures but may not lead to an immediate seizure-free result.

The ketogenic diet is started in the hospital, with the child fasting under close medical supervision for 18-24 hours before slowly introducing the diet. The diet is carefully prepared, with foods weighed and measured to restrict carbohydrates and protein. It is important to stick to the diet as prescribed, as deviating from it for even one meal may reduce its effectiveness.

The ketogenic diet may cause side effects such as sluggishness, nausea, constipation, and fatigue. It does not provide all the vitamins and minerals of a balanced diet, so vitamin and mineral supplements are recommended. The diet is usually considered for patients with epilepsy when there are no clear metabolic or mitochondrial reasons not to use it.

Ketogenic diet as a treatment for children with seizures

The ketogenic diet is a special high-fat, low-carbohydrate diet that helps control seizures in some people with epilepsy, especially children whose seizures have not responded to medication. The diet is carefully monitored by a dietitian and prescribed by a physician. It is usually started in the hospital, with the child fasting under close medical supervision for 18-24 hours before the diet is introduced.

The "classic" ketogenic diet is stricter than the modified Atkins diet, requiring careful measurements of calories, fluids, and proteins. Foods are weighed and measured. It typically provides 3 to 4 grams of fat for every 1 gram of carbohydrate and protein, which equates to about 90% of calories from fat. The diet is nutritionally imbalanced, so children following it will also need vitamin and mineral supplements.

The diet works by producing ketones in the body. Ketones are formed when the body uses fat for energy instead of carbohydrates. The body can work very well on ketones and fats, and higher ketone levels are often linked to improved seizure control. The diet has been shown to be particularly helpful for some epilepsy conditions, including infantile spasms, Rett syndrome, tuberous sclerosis complex, Dravet syndrome, Doose syndrome, and GLUT-1 deficiency.

Several studies have shown that the ketogenic diet does reduce or prevent seizures in many children whose seizures could not be controlled by medications. Over half of the children who go on the diet have at least a 50% reduction in seizures, and 10-15% become seizure-free. The diet is usually followed for about two years, after which it is slowly changed back to a regular diet.

While the ketogenic diet has proven effective in helping to control seizures, it is not without risks. Side effects occurring with long-term use include low bone density and bone fractures, slower growth than typical, and sluggishness or tiredness. It is important to note that the diet should be closely monitored by healthcare providers and should not be attempted without medical supervision.

Ketogenic diet as a treatment for adults with epilepsy

The ketogenic diet is a high-fat, low-carbohydrate, controlled-protein diet that has been used to treat epilepsy since the 1920s. The diet is usually considered for adults whose seizures cannot be controlled with anti-seizure medications (ASMs). The diet may help to reduce the number or severity of seizures and may have other positive effects.

The ketogenic diet is an established treatment option for children with hard-to-control epilepsy, but adults may also benefit from dietary treatments. The diet can be adapted to all ethnic diets, as well as for people who are allergic to dairy products. The dietitian will calculate the diet and try to include foods the patient likes.

The ketogenic diet can be used in children and adults of any age, although detailed monitoring may be needed for infants. The diet can be challenging to maintain in the long run due to restricted food choices. The diet is usually not recommended for adults, but the modified Atkins diet is a good alternative. This should be done with the support of a good team of adult neurologists and dietitians.

The ketogenic diet works by changing how the brain gets energy to function. The body usually uses glucose from carbohydrates as its energy source. When the body uses fat for energy, it produces chemicals called ketones (this is called 'ketosis'). With the ketogenic diet, the body mostly uses ketones instead of glucose for energy.

The ketogenic diet can be effective in treating seizures in adults with epilepsy. A clinical trial at Great Ormond Street Hospital in 2008 showed that the diet significantly reduced the number of seizures in a proportion of children whose seizures did not respond well to ASMs. After three months, around 4 in 10 (38%) children who started the diet had the number of their seizures reduced by over half, and they were able to reduce their medication. Other benefits included increased alertness, awareness, and responsiveness.

High-quality evidence for the effectiveness of dietary treatment for adults is increasing, and research studies are continuing to investigate how and why dietary treatments are effective for some people and not for others.

How does the ketogenic diet work?

The ketogenic diet is a high-fat, low-carbohydrate diet that is used to help control seizures in people with epilepsy, particularly children whose seizures have not responded to medication. It is usually prescribed by a physician and monitored by a dietitian.

The diet works by drastically reducing carbohydrate intake and replacing it with fat. This reduction in carbs puts the body into a metabolic state called ketosis, where fat becomes the primary fuel source instead of carbohydrates. Ketosis is a natural metabolic state in which the body uses fat for fuel instead of carbs.

The body typically uses carbohydrates (such as sugar, bread, and pasta) for fuel. Because the ketogenic diet is very low in carbohydrates, fats become the primary fuel instead. The body can work very well using fat for energy.

The ketogenic diet is typically made up of 70% fat, 20% protein, and only 10% carbohydrates. This means that, in a 2,000-calorie diet, you would consume 165 grams of fat, 40 grams of carbs, and 75 grams of protein. However, the exact ratio depends on the individual's needs.

It's important to note that not all fats are considered equal on the keto diet. While some healthy unsaturated fats are allowed (such as nuts, avocados, and olive oil), the diet encourages high amounts of saturated fats from oils, lard, butter, and cocoa butter.

Additionally, it's important to moderate protein consumption. This is because protein can be converted into glucose, which may slow the transition into ketosis.

The ketogenic diet has been shown to have numerous health benefits beyond seizure control, including weight loss, improved insulin sensitivity, and reduced risk of certain diseases such as type 2 diabetes, heart disease, cancer, and Alzheimer's disease. However, it also has some potential side effects and risks, including nutrient deficiencies, liver and kidney problems, constipation, and fuzzy thinking. Therefore, it is important to consult a doctor and a registered dietitian before starting the ketogenic diet.

Side effects of the ketogenic diet

The keto diet is a high-fat, low-carbohydrate diet that has been used to help control seizures in people with epilepsy, especially those who don't respond to anti-seizure medications. While the diet has proven beneficial in this regard, it also has several side effects, including:

• Keto flu: In the beginning stages of a ketogenic diet, people often experience a set of symptoms similar to the flu, such as decreased physical performance, headache, weakness, irritability, constipation, nausea, and vomiting. This usually passes within a few days to a few weeks.
• Bad breath: The breath may smell fruity and slightly sweet due to increased levels of acetone, a ketone produced by the liver from fat metabolism. This typically goes away within a few weeks.
• Leg cramps: Ketosis causes a reduction in water weight, which can lead to dehydration and loss of minerals, resulting in painful leg cramps. Staying hydrated and increasing mineral intake can help alleviate this issue.
• Digestive problems: Constipation is a common side effect, usually caused by insufficient fiber and fluid intake. Diarrhea may also occur in some individuals. These issues typically resolve within a few weeks.
• Increased heart rate: Dehydration and low salt intake can lead to a temporary increase in heart rate, which can be alleviated by staying hydrated and increasing salt consumption.
• Other less common side effects include kidney stones, raised cholesterol levels, fatty liver, and hypoglycemia.

Additionally, the keto diet may have long-term health risks, including vitamin and mineral deficiencies, as well as an increased risk of heart disease due to higher consumption of saturated fats. Furthermore, the restrictive nature of the diet can make it challenging to follow for extended periods, and weight regain is common if carbohydrate intake is increased.
