What was it like when you realized that you had become fat-adapted? Was there a specific experience that you can recall for us newbies that really brought it home; you had transitioned away from carb dependence and slipped the chains of food slavery.
Us newbies often lose hope as we are taking baby steps to stay the course and I think it would be endlessly valuable to hear from keto veterans about what it was like when the the lights came on. Cheers!
It was dinner time and I realized Iād forgotten to eat lunch. Happened about 4 weeks in.
My situation is a bit different because I started out low carb ala Atkins and didnāt know what āketoā was so wasnāt looking for anything but to stay in ketosis by keeping my carbs 20 or less and lose 30 lbs.
Howeverā¦ I do recall when I became fat-adapted even though I didnāt have a word for it.
Three days in a row I glanced at my watch and my eyes bugged out when I realized it was well past 2 pm and I FORGOT to eat lunch!!! WTH???
I wasnāt hungry. Usually by 9:30 or 10:00 Iād be starving and looking for a snack. I started skipping meals even though I didnāt know what IF was.
I was so happy to find this forum and learned so much! I was eating too much protein and not enough fat because I was following what I knew - Atkins. When I flipped the macros and ate more fat than protein I started having more energy and my weight started dropping again after a stall.
Isnāt is amazing after being a slave to being hungry all the flipping time???
I was about 4-5 weeks in also.
I was never really one for breakfast and always incidentally intermittant fasted for 16 hours daily.
I would always eat lunch at 12, then it became 1 and 2 and 3 and 4 and then suddenly I was eating ālunch at 5pmā and would not be bothered at all to eat dinner.
When I stopped THINKING about food 24/7.
I didnāt have āa momentā, maybe because my adaptation phase wasnāt that difficult except for being very tired. It was more like recovering from an illness, I went through a phase where I had a little more energy, then a little more, and then a few weeks later I realized I felt absolutely normal again (normal plus able to go days without eating, no more hangry and so on, that is.) Iām 55, female, and started 20-25 pounds overweight, Iād say adaptation took about 10 weeks altogether.
(Iāve also heard that this can keep on evolving, some people get better and better at fat burning over the years.)
Iād say my adaption happened sometime around Week 12 but for me it was quite subtle, you hardly notice that anything has dramatically changed. Just that you donāt feel as hungry, the digestive system has settled down, youāre pooping regularly, fat really does satiate you when you find yourself licking fat off the plate! You see carby food that used to make you hungry and its easy to ignore it. I could easily walk into KFC now and just have a coffee to be polite. All the keto flu symptoms disappear, no aches and pains, cravings have gone. You can still lose a lot of weight without being adapted but when you do adapt it just feels a lot easier.
For me, the onset of fat adaptation was rather subtle. I have some kind of chronic fatigue, the result of a bad viral infection back in 2006. I never recovered my stamina, and it used to be all I could do to get out of bed and go to work, so the result is that I donāt feel the zippiness that others on these forums report. What I do feel, however, is just about normal. But that feeling came on so gradually that I didnāt really notice, except one day I realized that I had exerted myself a few days earlier and hadnāt had to spend a couple of days in bed afterward, recovering. As Iāve posted recently in a couple of other threads, it may not be glamorous, but Iāll take it! 
Yesterday! I went for a walk and for the first time in a long time, I walked a 15-16 min pace and had a lot of energy. I have not been able to walk that quickly in years; mostly 20+min/mile pace. So amazing and I felt awesome afterwards.
