Soylent 2.0 is a popular meal replacement drink that is used to supplement or replace one's regular diet. Soylent is designed to fully fulfill one's nutritional needs, but its impact on the human microbiome remains unknown. This study aims to track the composition of participants' gut microbiomes before, during, and after Soylent consumption to more holistically understand its impact on microbiome health. We predict that a short term Soylent-based diet will induce observable and reversible changes to participants' gut microbiomes.
