i do not know
i was skeptical about sugar and flour some years ago because I was quite fat and tried keto, lost some good amount of weight.
But back then i just tried it out to see how it would go. Now eating things with sugar or flour make my stomach revolt, and get gag reflexes.
I blame it on eating a fuckton of refined flours and sweets after my mother died, and maintaining the shitty diet my dad has.
It will be an expensive way of living.
