Well done!!!
Glad you tested and refuted as a poster here is fond of saying “nutty keto dogma”
All us lay-people can do is report our own personal experiences, even when they don’t jive with conventional wisdom and people think we are lying.
Our bodies are amazing engineering marvels. Being a chemical engineer myself I can only observe and note data.
Again, I am one year in. Sometimes I can eat twice a day, other times, four times a day. I cannot fast due to GI issues. I had good energy and brain clarity prior to keto. I am excepting more health improvements. My trigs are way down, as is my FBG. When I was eating SAD, I cycled in and out of ketosis for years, because I had no appetite.
I have absolutely no idea. I felt better energy after the first week and that’s what stood out in my mind. I did notice around two months I usually didn’t feel like lunch, or it would be replaced with a snack. Eventually I realized two meals and no snacks was easy.
It was a process of letting go of habits and listening to signals. It’s gradual I think and continues to develop for a year or two. It’s not like one day you’re not fat adapted and during the night a Magic Keto Fat Adaptation Light Switch gets flipped. It’s more like those dimmable lights if you could sit there for a year or two turning it up, 6-10 weeks is just the beginning. 
Exactly!!!
I became fat-adapted before I knew what it was. I was working a shutdown with a crazy 12-14 hour workday and discovered I’d forgotten to eat lunch and it was after 3 pm. How the fuck did THAT happen?!
OK folks! This topic got me interested in why already fat adapted individuals, myself included, would show detectable acetoacetate on urine test strips. We’ve all been told repeatedly that ‘pee sticks’ are useless after two or three months and only useful at all to newbies. Well…maybe not. Maybe upon closer examination many of us fat burners are leaking acetoacetate and didn’t notice only because we didn’t bother to look. “Only useful for newbies, don’t ya know”.
So I decided to open a new topic to take a survey of forum participants on whether or not they have detectable acetoacetate:
Same here. The absence of hunger was a feature I had not learned existed in this Ketoverse. Its occurrence was stunning!
Fat adaption is a continuum/process, not an on/off switch. Therefore whether you are “fat adapted” or not is a difficult question. How far along the continuum is “fat adapted”?
[edit] A better question would be: how fat adapted are you? But then you have the question of how you measure this.
@Janie is right. This is just an oft repeated keto dogma. Most people here are aware that we continue to waste some ketones in our urine long after we are fat adapted. I think the problem is that there is a slight shift downwards and for some people that’s enough for negative results after fat adaptation. Since some people do show nothing after they are adapted it’s important to inform people concerned about a lack of a result, and who insist that they are doing everything else correctly, that the sticks my simply have stopped working for them. This doesn’t mean that it’s even the more common state of affairs however.
This is a REALLY Hard Question!
Why is the sky blue is easier to answer!
First, YMMV, and Every Body is Different.
Second, Define Fat Adatped?
For daily activities?
For Gym Routines?
For Intense Workouts/Hikes?
For doing an Ultra Marathon?
I liken the understanding of this to:
I have been (with the exception of a couple of days) in Ketosis since July 2018. And I feel I have barely made it to #3 above. I can walk 20+ miles in a day, fasted. I was NEVER a runner… But I feel over the next couple of months, I may have enough energy and health to actually run a bit.
But your question begs clarification.
How long before you felt NORMAL in ketosis might be what you are asking.
And that took WEEKS for me, with small milestones showing up every couple of weeks, for a month or two.
I’m glad you started the other thread so the newbies who have become fat adapted but still turning pee sticks purple don’t think they are doing something wrong or that they may not be fat adapted yet.
It would be nice if we could measure fat adaptation with a blood or urine test and not rely on observation of symptoms, but there isn’t.
It is certainly revealing some very interesting stuff, I’ll admit. Apparently quite a few people whom I don’t think could be called newbies are turning colours. @Alecmcq above and someone on that other topic, I think @RobC, described ‘fat adaptation’ as a likely never-ending process rather than some achieved static state. I agree 100%. Also, I think there’s an interesting process of study and discovery to try to determine why some people well into fat adaptation dump ketones in their urine while others don’t. I realize that the process of human metabolism and specifically fat metabolism can best be described as ‘good enough’ systems rather than ‘flawless’ systems. So maybe good enough is flexible enough to cover all the bases. Fascinating even if confusing.
