Yeah sorry for the confusion. I just meant that ketones are a result of the diet. >> Regardless, do you feel the microbiome manages to shift that drastically within 24-48 hours? No, but the population doesn't have to change in order for us to notice the effects of changing our diet. Changing the food we eat and subsequently send to the organisms in the microbiome affects what the various constituent bacteria/fungi metabolize and excrete. These excretions can have rapid effects on us. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9877435/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9877435/ In the longer run, starving some species out and promoting others to take their place would yield a more permanent effect.
