Different people have different hormonal response rates to entering ketosis, however, as the pubmed article I linked [PMID: 12026232] showed, average was 33 hours for onset and 58 hours (ranging from 40 - 84h) to reach good ketosis. This was for young people, new to ketosis.
Ha!
Again you skew the facts, MrHappy. The study is of
children and the keto diet is
therapeutic, which implies the ratio you guys never even come close to. And yet you apply it to yourself. I'm glad it's children studies rather than rats though. That's a step in the right direction. Still, children have a much larger brain to body ratio than adult males (especially heavy adult males), and this ratio determines the rate and degree of induced ketosis.
The other thing about children, not shared by adults, is that they are still metabolically very flexible. Adult males have very different response rates. They are all the way in the other end of the spectrum, significantly slower than adult females. So, if you use the same draconian keto ratio, you, as an adult male, should multiply their results by at least 2, better 3.
So, this study has nothing to do with you, MrHappy. Especially considering that the ratio you personally used in your diet was about the reverse of the therapeutic ketogenic diet. Considering that you never used ketostix nor blood glucose or ketone monitor, and now you're saying that neither did you really suffer during the induction.. I seriously doubt you were ketotic enough to induce anything in the first place..
alecnevsky, yes MCT oil delayed the real transition to ketosis, even though the calories it provided were mainly in the form of ketones. It's because it is liver glycogen stores and blood glucose level that decide when this transition occurs. When fasting, any source of calories, in whatever form, will delay it.
If you had under 30g of carbs a day and the ketostix showed high levels in the morning, your issue is not whether you were in ketosis but your adaptation to it. Generally, the more draconian are the measures the faster it happens. Fasting is the quickest way and it takes about a week to 10 days for the beginners, but seasoned pros can do it in 5 days. Last time I fasted I got there in the morning of the 7th day.
MrHappy, this is the first stage of
adaptation we are talking about here. I believe that's 2-3 weeks talked about by Schwatka in the quote above. Compare 7-10 days it takes on a fast with 2-3 weeks in the field on reindeer meat and then consider how long it should take on a skimpy keto ratios with tons of protein you guys usually use.. There is no way in hell that you can
adapt in less than a month. It's probably more than 2, just like Chupo said. I saw on paleohacks today that Dr. Kruse believes the full adaptation to a keto diet takes longer than a year.. -?! well, maybe it's for the ex-obese and ex-sedentary folk..
