Anyone find that they get a lower estimated GFR for kidney function on a
high protein diet due to the increased protein level and did it go away
by increasing complex carbs and/or fat along with not over indulging in
too much protein?

I'm thinking of managing my protein level to something like 100 grams
from meat/egg/cheese sources and see what effect that has on kidney
function. Otherwise, my kidney function has always been good and even
the creatine/bun levels that are used to do the eGFR estimate are within
normal range although the fluctuate from mid range to high normal from
test to test.

In the short term your GFR will drop as you reduce protein, seems
backwards I know.
The idea is that having a higher GFR is hard on the kidneys and will
result in a long term reduction in GFR, for people on a high protein
diet.

You might want to look at this study.

So if you reduce you protein intake don't be surprised is you see a
drop in your eGFR, but this is a good thing really.

How so? Lower eGFR is indicative of worsening kidney function. My
inital thoughts were that a high protein diet and a lot of exercise was
producing false low eGFR readings since it is estimated based on blood
creatine which can be elevated by exercise and high protein diets.
