Do you feel the same with food that is both sugar and fiber, such as fruits? My understanding is that the fiber slows down the metabolism, and thus the sugar is processed much slower.
I also did Keto for a while though and after you've been on that and then you just eat something made from flower again not even with sugar in it it tastes sweet. That was eye openingly weird. Of course that goes away quickly if you start eating it regularly again even if in low quantities.

We have a lot of feedback systems. I find I do the best when I don't push too hard in any particular direction. I try to let my needs guide my actions without too much deep introspection or trickery.
There are structures in our brains that served our ancestors well for millions of years, and I try not to out think them or get in their way.
