Clinical and Financial Research

LMI is committed to research that bolsters and strengthens lifestyle medicine. LMI is the founding member of the American College of Lifestyle Medicine Economic Research Consortium (LMERC). LMI continues to focus on research projects that are focused on clinical and financial efficacy for lifestyle medicine.

Pivio builds upon the foundation of its forerunner, CHIP (The Complete Health Improvement Program.) More than 40 peer-reviewed research papers prove CHIP’s efficacy in helping to prevent, treat, and assist in the reversal of chronic disease.
