Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Human beings react differently to changes in diet, exercise, and sleep patterns. The goal of this study is to (1) learn how individuals react to lifestyle choices and suggestions by examining a small group of people with similar health and lifestyle profiles; and (2) to develop algorithmic policies (male/female) that will help people optimize their health through lifestyle interventions and supplementation with prebiotics.
