On the ketogenic diet, carbohydrates are restricted and so cannot provide for all 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 cannot 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 cannot be used only to produce glucose. This could pose a problem for the brain, since it is normally fuelled solely by glucose, and most fatty acids do not cross the blood–brain barrier. However, the liver can use long-chain fatty acids to synthesise the three ketone bodies β-hydroxybutyrate, acetoacetate and acetone. These ketone bodies enter the brain and partially substitute for blood glucose as a source of energy.

The Johns Hopkins Hospital protocol for initiating the ketogenic diet has been widely adopted. It involves a consultation with the patient and their caregivers and, later, a short hospital admission. Because of the risk of complications during ketogenic diet initiation, most centres begin the diet under close medical supervision in the hospital.
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; insufficient breakdown of excitatory neurotransmitters leading to excess; immature synapse development; and impaired function of ionic channels.
Milestone 3: intermittent fasting. This one may come on pretty naturally at any point when you start realizing that you're not eating because you're hungry but because you're bored. Cutting out breakfast was the first step for me and switching to black coffee, then I naturally fell into an eating window of noon to 7:00 p.m. I would eat my lunch at noon and dinner at 7:00 and that was enough for me and my body to feel comfortable.
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.
It seems strange that a diet that calls for more fat can raise “good” cholesterol and lower “bad” cholesterol, but ketogenic diets are linked to just that. It may be because the lower levels of insulin that result from these diets can stop your body from making more cholesterol. That means you’re less likely to have high blood pressure, hardened arteries, heart failure, and other heart conditions. It's unclear, however; how long these effects last.
There are theoretically no restrictions on where the ketogenic diet might 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 labelling is not mandatory so calculating the proportions of fat, protein and carbohydrate is difficult. In some countries, it may be hard to find sugar-free forms of medicines and supplements, to purchase an accurate electronic scale, or to afford MCT oils.
I never set out to lose a certain amount of weight when I started, I just wanted to be healthy for myself and my kids. In the beginning it was tough, I was used to eating a whole large pizza with ranch for dinner, or 3 grilled cheese sandwiches dipped in barbecue sauce. Veggies were eschewed unless they were a topping on my cheeseburger. I remember my first week I packed a salad with chicken and bacon and blue cheese dressing, and that was pretty good. Then I made some brats and sauerkraut and mustard with a side of broccoli. Hey this isn't so bad. I got in to the habit of picking a protein and a veggie and mix and matching for variety. Chicken, pork chops, brats, steak, and broccoli, Brussels sprouts, asparagus, green beans were my staples. I didn't weigh or count macros, I just avoided the bad carbs and focused on the good. https://philosophyofhealthorg.tumblr.com/
