Use of Patiromer to Transition Chronic Kidney Disease Patients With Hyperkalemia to a Plant-rich Diet.

Patiromer dosing will be determined based on fasting potassium concentrations measured at the end of each week, factoring in both the absolute concentration, as well as the rate of change. The baseline dose of patiromer will correspond to the study by Weir et al. (2015); 8.4-g once per day for participants with a baseline serum potassium of greater than or equal to 5.1 mEq/L.

During the study, participants will be asked to consume only the foods provided in the research diet
