A continuous glucose monitor (CGM) will be provided for use during the study. Additionally, they will use a smartphone application to track nutrient intake, self-monitor biomarkers, implement mindfulness practice, and participate in facilitated discussions to build community support. Each participant will meet remotely with the renal dietitian and complete laboratory safety monitoring throughout the program to tailor dietary recommendations for optimal compliance.
