Measure
Patiromer + Research Diet
During the first phase (week 2), participants will be transitioned to a plant-rich renal diet, which contains moderate protein (10-15% of kcal), restricts dairy products (less than or equal to 1 serving/day), and eliminates high-potassium fruits and vegetables. During the second phase (weeks 3 and 4), the diet will be altered to provide at-least half of fruits and vegetables from high-potassium sources. Patiromer: 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. Research Diet Menu: During the study, participants will be asked to consume only the foods provided in the research diet
