For patients who benefit, half achieve a seizure reduction within 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 half of the patients to achieve an improvement is longer (two weeks), but the long-term seizure reduction rates are unaffected.[44] Parents are encouraged to persist with the diet for at least three months before any final consideration is made regarding efficacy.[9]

Hey Alex, thanks for commenting and great to have you as a new listener! For this kind of thing, because it requires so going into detail, I'd suggest you book a consult with me by going to
A Cochrane systematic review in 2018 found and analysed eleven randomized controlled trials of ketogenic diet in people with epilepsy for whom drugs failed to control their seizures.[2] Six of the trials compared a group assigned to a 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.[2] In the largest trial of the ketogenic diet with a non-diet control[16], nearly 38% of the children and young people had half or fewer seizures with the diet compared 6% with the group not assigned to the diet. Two large trials of the Modified Atkins Diet compared to a non-diet control had similar results, with over 50% of children having half or fewer seizures with the diet compared to around 10% in the control group.[2]
High levels of circulating ketones may have a direct appetite-suppressant effect. In fact, the exogenous ketone ester used in HVMN Ketone rapidly increased blood levels of beta-hydroxybutyrate and lowered appetite as well as levels of ghrelin - the hormone that increases hunger. While this still needs to be explored further, it is possible that exogenous ketones may be useful for appetite control as part of a holistic weight loss strategy.11 

Keto is short for ketogenic. If you didn’t already know, it’s a high-fat, low-carb diet. The goal of the ketogenic diet is to get your body into a “ketogenic state,” or a physiological state in which your body is not burning carbohydrates -- which break down to glucose -- but an alternative energy source called ketones, which are produced by the liver when your body is depleted of glucose. Ketones are formed from fat stores. In order for your body to start producing ketones, it needs to first run out of glycogen stores. After you deprive your body of carbs, it takes a bit of time for the glucose to clear out.
Because some fruits have more carbs than others, knowing which to avoid is key for accelerating weight loss and reaping other possible benefits of keto. Just know that large, long-term, randomized controlled trials on the keto diet are limited, so it’s unclear whether keto is safe and effective to follow for the long haul, according to Harvard Medical School.
The ketogenic diet is indicated as an adjunctive (additional) treatment in children and young people with drug-resistant epilepsy.[26][27] It is approved by national clinical guidelines in Scotland,[27] England, and Wales[26] and reimbursed by nearly all US insurance companies.[28] Children with a focal lesion (a single point of brain abnormality causing the epilepsy) who would make suitable candidates for surgery are more likely to become seizure-free with surgery than with the ketogenic diet.[9][29] About a third of epilepsy centres that offer the ketogenic diet also offer 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.[9] 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.[5][30]

Fascinating stuff and I am quite curious how we know for certain one is actually in ketosis i.e. using ketones as primary fuel source BECAUSE we do know that glucose has a shorter metabolic pathway to burn and under most conditions, given the presence of glucose, that is what the body will default to which is why high fat and high sugar together in diet is so detrimental. So if we use one or more of the above “boosters” and show high levels of blood ketones but also highish levels of glucose (during initial transition) will be mostly burning ketones or still defaulting to glucose?
