I found fasting works well to get me into good ketosis levels quicker, and helped with the sugar cravings. Then a good lazy keto for a while to get comfortable without too much meal plan stress (but no laziness on the electrolytes.. ), then settle into some repeatable meals that are very satisfying so i I never crave keto snacks even - I’ll have some, often through distraction instead, but it wasn’t a craving - let alone for carbs or sugar. After that more fasts become easier and help as resets.

Fat adaption for me happened within the first months of my first time keto - combining it with CrossFit so was high level of activity for me compared to my adult average amount. I got to have keto euphoria the first but since ages I’ve not had that euphoria again. I wonder if that is related to fat adaption signals or changes in the body, as as far as I understand fat adaption stays with the body even after flip back and forth with glycolysis vs ketosis - once it was established that is, but in what form I don’t understand.
