I just got back my latest lab results. I initially followed Lee Hull's book stopping kidney disease but lost too much weight so I had to modify it slightly. I went totally vegan which means I have lentils, nuts etc which is not strictly on his plan.
last 3 GFR results after switch were 49,47,52. Last 3 before switch were 40, 36, 42. That is a 25% increase in GFR.
BUN was 16, 19, 17 after switch. Numbers before were 28, 25, 25. That is a 33% reduction.
I think anyone new to this community who needs to improve their kidney function has to consider giving up meat and dairy. As Lee Hull explains in his book you need to reduce the load on your kidneys.
