PLADO for Conservative Management of CKD

The goal of this clinical trial is to learn if a plant-dominant low protein diet, referred to as PLADO diet, works to decrease metabolic acidosis, a major risk factor for chronic kidney disease (CKD) progression, in adults with CKD. It will also learn about the safety, viability, and economic attractiveness of this diet. The main questions it aims to answer are: * Is the PLADO diet more effective in managing metabolic acidosis in comparison with the standard-of-care CKD diet in adults with CKD? * Is the PLADO diet safe, viable, and economically attractive adults with CKD? Researchers will compare the PLADO diet to the standard-of-care CKD diet to see if the PLADO diet works better to decrease metabolic acidosis. Participants will: * Receive nutrition education of the PLADO diet or the standard-of-care CKD diet via monthly sessions for 6 months. * Visit the clinic monthly for 6 months, then after 3 months for checkups and tests.
