Back on 11/6/2024 my Phosphorus was 4.6 mg/dL and recent test on 2/6/2025 was at 5.4 mg/dL. So, the rise of 0.8 mg/dL is during my 112 days on Carnivore (almost 4 months).  But, I can not say it is definitely "caused" by those RibEye steaks... It may have risen more or less if I never went Carnivore. 
I also do not know if 5.4 mg/dL is a small or big issue. 
I'm would also like to know if exercise (walking and weight training) would potentially help decrease the Phosphorus level.
Carnivore has already greatly improved my CHF and overall feeling of good health.  I am convinced that if I went back to the pre-carnivore lifestyle my recently gained health benefits would mostly go away.  That is NOT an option.
ALL the comments above are greatly appreciated. 

I just listened to Bob's Video - "Will Carnivore Heal My Kidneys Now?? " ... and I'm very pleased to hear a person that is dealing with Stage 4 CKD as I am... suggesting that there is hope for me and others with the Stage 4 situation to deal with. I'm an 85 year-old Carnivore for 112-days so far, and feel great!  I was diagnosed with CHF about 10-months ago, before going Carnivore, and my cardiovascular is showing signs of slowly improving.  No other health issues.
My situation is that my Nephrologist just told me a few days ago that my Blood Test shows PHOSPHORUS is up to 5.4 mg/dL and he wants me to start taking a med to "binder" (Sevelamer Carbonate) with all its side effects ... to lower the level back to 4.1 mg/dL or lower. Says 5.4 level is very BAD! While my other numbers are reasonable and not a problem. Anyone know how to lower PHOSPHORUS level while staying on Carnivore Lifestyle. 
Being on Carnivore for 112 days, I'm not sure where all the Phosphorus is coming from... (probably the RibEye steaks?!?!) ... I do not know if 5.4 mg/dL is sooo Bad... That is why I have Signed up with your Carnivore Community... praying that I can find hope in the world of folks that may have dealt with this issue.

How is your Vitamin D? Calcium? I'm reading about the kidneys on carnivore right now because my creatinine levels sort of jumped. Nothing all that alarming but it was a pretty good shift.
I'm asking because Vitamin D helps with phosphorous and calcium absorption in the body to help maintain a metabolic balance between the two. I have read 2:1. 
Hopefully you figure it out. Congrats on the 112 days.

First of all, WELCOME, and welcome to the best natural way of eating on the planet!  Carnivore has helped me get my life back, and this is a great community.

Others that know much more than myself may correct me on this, but to my knowledge, for those with kidney trouble, one of the things that can build up to excess in the blood is phosphorus.  Sevelamer Carbonate binds up a lot of this phosphorus in the stomach to prevent initial absorption, thus reducing the high blood count later on down the line.
Side effects look to be generally mild, and in line with what would be expected from a binder.  Our bodies do NEED phosphorus of course, but in balance. If they can get the dosage dialed in correctly, it may be a helpful medication to take while healing happens on the carnivore diet.  With proper nutrition and fasting, it may be possible to reduce and eventually come off the medication as levels naturally improve.  

I am on insulin for type 1 diabetes, and carnivore has enabled me to steadily decrease the amount I am on (by a great amount!) but I would be VERY sick without it at this point.

That all being said, some of the "helpful hints" the medical establishment may throw at you to reduce phosphorus are 
1) Discontinue eating red meat
2) Supplement with high levels of vitamin D

I personally would steer clear of these recommendations, to put it mildly.
