I switched to a plant based diet and found it was helpful with weight loss and helped maintain kidney function for now. There are some free resources on-line and one I follow and have gained so much insight from is the YouTube channel “Plant Based Kidneys” with Michele Crosmer, RD, a renal dietician. She offers many Kidney friendly recipes for free and a lot of great information. I have purchased valuable resources from her as well that have helped tremendously but it isn’t necessary to purchase anything.
