Increasing fiber intake is not necessarily required for a healthy microbiome, and decreasing fiber does not automatically lead to an unhealthy microbiome.

“people still think you need fiber for a healthy gut microbiome I don't buy it”

“and this is the murkiest discussion and my good friend Tommy Wood has enlightened me regarding the word Tassie ography which is reading tea leaves so what I would say about the microbiome is at this point in time it's mostly Tassie ography and many of the claims regarding fiber in the microbiome I would say are overblown and they are extrapolations I don't think that there's evidence that we really know what a healthy microbiome is and which organisms we should have in there”

“therefore if you decrease the fiber you're gonna have an unhealthy microbiome this is about 20 steps to premature”
