When I see a whole article based on the situation of one person, I immediately discount it.  Good chance the Pharma companies are behind this crap.  Classic effort to motivate with fear.

But... why don't we do a survey of CT folks...

Who has had kidney stones while on Carnivore?

 

 

 

According to the study...

"A 61-year-old male with a long-standing history of nephrolithiasis presented to kidney stone prevention clinic for evaluation. His first stone was observed incidentally on X-ray at age 45. He was asymptomatic until age 55, after which he passed ∼3 stones per year until age 58 without complications. Stones over the next 3 years were accompanied by pain and difficult passage."

So this guy churned out stones like a quarry long before he went on a carnivore diet.

"The patient’s increase in urine oxalate is of particular interest as the effect of high animal protein intake on urine oxalate is disputed. Oxalate is found in higher quantities in some plant foods, including spinach, almonds, soy products, potatoes, and raspberries, so one might predict this value would decrease with reduced plant consumption"

His previous diet may have been oxalate-rich, and he was oxalate dumping. 

The above urine studies demonstrate an increased risk for the development of all 3 major stone types: calcium oxalate, calcium phosphate, and uric acid, as indicated by the increase in supersaturation values... he subsequently stopped the carnivore diet. One year after discontinuing the carnivore diet, the patient was stone-free without urologic symptoms... Though improved from when on the carnivore diet, some stone risk factors were still out of the normal range, including urine citrate, PCR, and UUN. The patient admitted his enjoyment of animal protein made it difficult to dramatically reduce consumption.

It's worth noting that this individual NEVER actually did get kidney stones while on his carnivore diet. Only his "risk factors", that is, his lab work, gave some cause for concern.

New York Post lol. Enough said. 

Yeah that’s a bunch of bovine excrement.
You don’t created stones from just a few months on Carni or any other diet for that matter.
He had those stones for years from eating oxalate rich foods.
What can happen on carnivore is that kidney stones that are already present can shrink and then slip down the urinary tract.
Everyone is always trying to bash the carnivore lifestyle with fear mongering, false science and just plain ignorance.
