The non-core microbiome as a driver of general composition change. A All ASVs with prevalence above 3%, ordered by prevalence across all samples. “core” taxa were defined as > 50% prevalence, with the remaining taxa defined as “non-core.” B PCoA stratified by the non-core (<50% prevalence, top) and core microbiome (>50% prevalence, bottom). The compositional shift of the Green-MED group originated from the non-core (rare) taxa with a significant interaction between time and group in PERMANOVA. C Differences in within-group dissimilarity and between-group dissimilarity, by non-core (green points) and all taxa (gray points) microbiome composition. The Green-MED dieters’ microbiome composition assimilated each other at the 6-month point. This effect was even more dominant in the non-core fraction of the microbiome. Violin plots describe the distribution of 106 random permutations of the same measure, shuffling sample labels at each iteration
