UMM. Grr. I really WISH that I agreed, because that's what I thought the first read through, but then I re-read it a couple times. I wish it were true, because all I eat on my diet is meat, eggs, fish butter and cheese, but I'm not sure you're right.
It's not just Egfr (Estimated gfr) they're concerned with, it's GFR they're measuring directly, which is seldom measured in routine tests, probably because it's invasive and expensive and Egfr is cheap and easy with a blood test.
So best as I can make sense of things that spark the concern of these scientists and doctors, is that
measured GFR is significantly increasing, because the blood pressure inside the glomerulus is increasing with increasing protein intake, which leads to increased filtration in the short term, but increased fibrosis (damage) in the long term.
Now maybe the EGFR is returning to normal in cohort studies because of a homeostatic mechanism, (I hope and suspect it is) but .... I don't know, and they didn't theorize that in the paper.
I really hope that the gfr goes down in the long term, because the body is adapting and lowering glomular blood pressure, because increased systemic blood pressure DOES lead to kidney damage long term, we know this for a fact, epidemiologically, so increased blood pressure inside the glomuerulus in the kidneys, is not a good sign.
Maybe the EGFR is just returning to normal because the pressure is going down as the body adapts, maybe the EGFR is going down because it is signalling early stage kidney damage?
I'm not sure, and I don't think the writers of the paper are sure, but I think with the (basically carnivore) diet I'm on, I'm going to start by tracking my macro's, not just total carbs, then maybe trying to replace some of the protein in my diet with fats, and also maybe getting my EGFR checked twice a year instead of just once, to catch any warning signs early.
The one cohort of people that has eaten high protein for decades is Bodybuilders, and they do have a higher incidence of early kidney failure from what I've seen, but they also use gear, so is it the high blood pressure from gear?, the high intraglomular pressure from high dietary protein?, or both? or maybe neither?, maybe it's the orals. I do realize, that I am among the first large group of people to be using the carnivore/keto diet as a lifestyle, so .... I am taking a risk.
I really don't want kidney failure, it's a shitty way to die, it takes years on dialysis, as one major vascular access point after another blows out, knowing that with each destroyed vein/artery point you get one step closer to being sent home to die, waiting in vain for a kidney transplant that's not going to come because they only go to very young people.... Yeah..... Fuck that's a shitty way to go.
