Hmmmm… fair point. Then it would be a question of: does the same thing happen to people who are fat adapted? Does it only happen to carb burners because they are carb burners? For me, I stalled out when I did not eat enough (and even then it was probably 1200 calories or so), but that could have been because my insulin was too high (which I am lowering with extended fasting). I’ve also seen the “you’re not eating enough” response to people who have stalled before too - though that is anecdotal. So, then, the question is assuming your insulin is low enough could you calorie restrict (not fast, but actually calorie restrict) to lower body fat percentage. I completely misunderstood your question, lol, that is all on me.
It is an interesting one though.
I think, again, it would come down to “it depends on the person” but I am sure there are some seasoned keto veterans who could better answer it.
Sorry for misunderstanding!
