Just my fantasy scenario, imagine if some kind of yeast/virus affects humans to eat so much sugar, we never need so much sugar, but there's some-kind of yeast inside us that controls us, to create and consume sugar for it.

As far as I am aware this is a legitimate theory and angle of study around the guy microbiome, not just a fantasy.

I think the gut microbiome can indeed do this.

The episode called "Swap Out Sugar" of the BBC podcast Just One Thing explains more - the relevant section is from after 7 minutes to before 12 minutes into the episode:

AFAIK, it's not anything close to "known". But it's an open possibility that is being actively researched and has some supporting evidence.

Depends on your epistemology, I guess.
