What Does Ketosis Do To Your Kidneys

How Does Keto//os Affect Kidneys And Liver And The Role In Metabolizing Ketones?

As with all medium chain triglycerides, the MCT powder portion of the product will largely be converted to ketones by the liver within a few short hours of consumption. MCT create a readily supply of Ketone production for the liver to use for ketones. The BHB-salt portion should simply be absorbed into the blood as ketones. The BHB supplies another source, which doesn’t require the liver to produce ketones. There is no reason that the ketones produced by the product will affect the kidneys or liver any differently than ketones produced from exogenous fats (such as when eating a ketogenic diet) or ketones produced from stored fats (such as when calorie restricting or losing weight). Exogenous ketone scientific literature does not suggest that either kidney or liver function is negatively affected by ketosis. The major role of the kidneys when it comes to ketones is to excrete excess ketones in the urine. This excretion will likely be highest during the first few days of keto-adaptation (either in eating the keto diet or consuming KETO//OS), but the body will retain more and the tissues will begin to preferentially burn the ketones as consumption continues. The liver is the major s Continue reading >>

    So I went to the pharmacy yesterday to pick up a new scale and some Ketostix. The pharmacist (who works right next door to me and I've become friendly with) asked me if I was "starting some kind of crazy diet." I told him I've started a ketogenic diet and I'm just trying it out to see if it's right for me. He asked me a few questions about it, mostly about macro ratios and if it's been working so far. When I told him about the higher fat ratio (as opposed to high protein) he seemed somewhat intrigued, but still a little skeptical. The other pharmacist who was working with him chimed in at that point. He said apparently in some Scandinavian countries, they've found that a higher fat content and fewer simple carbs in a person's diet is ideal and actually recommended. However, they both agreed that ketosis for an extended period of time can be very hard on the kidneys. I did a little investigating on my own and there's very little info regarding the long-term effects of the high fat/moderate protein/low carb keto diet. So my question is, has anybody experienced any kidney issues on this diet? Has anyone received any similar warnings from their physician?
    TL;DR
    Pharmacist warned about kidney issues caused by long term ketosis. Seeking out facts/sources to prove or disprove this claim.

    When I first started keto I ended up going to hospital because I had severe internal pain that wouldn't go away. Turns out I was eating far too much protein so my kidneys were giving me grief. Fixed it by upping the fat macros in my diet and I went back to being pain free. Hooray for butter and coconut oil!
    Given my experience, I can understand where the pharmacists are coming from since I think there might* have been a spate of people doing atkins-like diets with kidney problems in the past (too much protein, not enough fat).

    I don't blame them for that at all. In fact, before I really started doing my homework on keto, I used to internally roll my eyes when people would talk about low carb dieting. I think there's a lot of risidual negativity held over from the early days of Atkins regarding low carb diets. Fortunately, I'm always happy to have a teaching moment when the chance arises!
