A systematic review in 2016 found and analysed seven randomized controlled trials of ketogenic diet in children and young people with epilepsy. The trials were done among children and young people for whom drugs failed to control their seizures, and only one of the trials compared a group assigned to ketogenic diet with a group not assigned to one. The other trials compared types of diets or ways of introducing them to make them more tolerable. Nearly 40% of the children and young people had half or fewer seizures with the diet compared with 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 in that trial were common, with about 30% experiencing constipation.
Even if you are starting a ketogenic diet plan for weight loss purposes, don't focus on your weight. Don't weigh yourself every day. Your weight can vary between 2-4 pounds each day because of changes in water intake and absorption. You won't be able to track any fat loss accurately on a daily basis, and the fluctuations will make you crazy if you focus on them. Instead, weigh yourself once a week, or keep track of your body measurements to track your progress. Better yet, focus on the health benefits and the long term health changes that come with eating a low carb diet. Knowing that you are greatly improving your health is a powerful reason to stay with a ketogenic diet plan, even if you don't lose any weight. I discuss in more depth the health benefits of a ketogenic diet in this article published in the July/August issue of the Well Being Journal. I recommend getting a health check up and a blood panel test done just before starting the diet, so that you can track the effect of the change in your eating habits on your cholesterol, blood pressure, and other health markers. Four to eight weeks later, you can get another blood test done and see if there are improvements.
The nerve impulse is characterised by a great 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 ion channels is governed by a "gate" which is opened by either a voltage change or a chemical messenger known as a ligand (such as a neurotransmitter). These channels are another target for anticonvulsant drugs.
As you transition from three meals to two meals or even to one meal a day, you will need to consume more fat. There are all sorts of great desserts you can create that support your weight-loss program. There are also keto bombs, which are fat-rich cookies that can be consumed at the end of the meal to make it incredibly easy to do intermittent fasting. Here are some examples:
In Asia, the normal diet includes rice and noodles as the main energy source, 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 due to cultural opposition towards 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.
Ketosis is a state of physical being and energy utilization when the body is running on ketones instead of glucose. Ketones are a clean fuel the body and brain absolutely loves. Ketones are an alternative fuel for the body that is not sugar or glucose. Running on ketones is like running a car on electricity rather than diesel fuel. Ketones are a cleaner fuel source - an alternative fuel source that gives a person way more energy than glucose. Even professional athletes can outrun and outperform any other athlete on ketosis than carb loading. By lowering your insulin, your sugars and refined carbohydrates, way down there close to zero to 5% of your daily calories or lower, you will burn fat as opposed to glucose for diet purposes or because you want to run on this clean fuel that many people find can help them perform better in all areas of life, mentally and physically. When you’re running on glucose and insulin is spiked, you’re not dipping down into your fat stores for energy. You’re burning up your muscles, not fat. When you’re in ketosis, you’re no longer spiking your blood sugar and you begin running on your own fat for fuel, which is idea for losing weight—the right kind of weight—fat.
In a recent study in the Journal of Sports Medicine and Physical Fitness, Weiss and his colleagues found that participants performed worse on high-intensity cycling and running tasks after four days on a ketogenic diet, compared to those who’d spent four days on a high-carb diet. Weiss says that the body is in a more acidic state when it’s in ketosis, which may limit its ability to perform at peak levels.
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 treating the seizures and some other symptoms in these diseases 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 metabolise fatty acids, which replace 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.
During the 1920s and 1930s, when the only anticonvulsant drugs were the sedative bromides (discovered 1857) and phenobarbital (1912), the ketogenic diet was widely used and studied. This changed in 1938 when H. Houston Merritt, Jr. 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 this time restricted to difficult cases such as Lennox–Gastaut syndrome, declined further.
The first modern study of fasting as a treatment for epilepsy was in France in 1911. Twenty epilepsy patients of all ages were "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 imposed restrictions. The diet improved the patients' mental capabilities, in contrast to their medication, potassium bromide, which dulled the mind.
As for branched-chain amino acids, you'll find smart people who swear that they're keto-friendly, and others who don't. One of the BCAAs, valine, can be glucogenic, meaning that it can lead to glucose production and potentially contribute to leaving ketosis behind. But does that mean it will happen? Not necessarily, particularly if you're just an occasional supplement user.
The main proposed benefit of the keto diet is losing weight, though there is some research showing it may help with certain health conditions. The weight loss comes because the body burns fat and because the fat you’re taking in is filling, which can lead you to eat fewer calories overall, says Abby Langer, RD, founder of Abby Langer Nutrition, who is based in Toronto, Canada.
There are so many tricks, shortcuts, and gimmicks out there on achieving optimal ketosis – I’d suggest you don’t bother with any of that. Optimal ketosis can be accomplished through dietary nutrition alone (aka just eating food). You shouldn’t need a magic pill to do it. Just stay strict, remain vigilant, and be focused on recording what you eat (to make sure your carb and protein intake are correct).
