I am 69 and have Polycystic Kidney disease. Egfr 37. Egfr was 51 two years ago. I have a renal dietician who suggested Keto diet. (Plant based). I called a top Nephrologist I knew at Boston’s Tuft University hospital-Dr. Ron Perrone. He said there are not enough studies on safety and efficacy for keto diets. He said follow a reasonable heart healthy diet like the Mediterranean diet. My nutritionist agreed with Dr. Perrone. She did say that I need to cut out white sugar and processed foods and continue to drink plenty of water. I bought the book: The Cooking Doc’s Kidney-Healthy Cooking book by Blake Shusterman, MD. It has delicious recipes, motivational stories and the latest science. My egfr remains stable at 37 and I feel good. He is on youtube and even has interactive podcasts to answer any questions you may have on diet and kidney disease. Very helpful to me!
