Are Low-carb Diets Safe For The Kidneys?

A new study eases long-term concerns regarding the potential adverse effects low-carbohydrate diets may have on the kidneys. Low-carb, high-protein diets—such as the Atkins diet—have been popular for years, but experts have long worried that these weight loss strategies may have harmful effects on a person’s kidney function or fluid and electrolyte balance. As far back as the 1970s, the American Medical Association even released an editorial labeling the Atkins diet "potentially harmful." “The belief among many experts was eating lots of protein could ‘rev up’ the kidneys, like an engine, and cause damage or failure over time,” lead researcher Dr. Allon Friedman, from the Indiana University School of Medicine, told FoxNews.com. “High levels of protein have also been known to change electrolytes in the blood in ways that could be harmful,” he added. However, in a study of 200 obese patients who participated in a low-carb, high-protein diet over a two-year period, Friedman and his colleagues did not find any noticeably harmful effects on kidney health or function compared to people who ate a low-fat diet instead. “We did not find that a high-protein diet led to an Continue reading >>

    Ketosis can cause damage to kidneys and liver

    So I'm about to fire up a keto regiment (again, I always fall off the wagon after about 2 months). Just searching around as it seems the other two times I started it I tend to have diarrhea a lot. Anyway, came across this. Any truth to this?

    When protein is deflected in this manner, it releases nitrogen into the blood stream, placing a burden on the kidneys as they try to excrete excessive urinary water due to sodium loss. When fat is likewise deflected, the breakup releases fatty acids, or ketones, into the bloodstream, further burdening the kidneys. If ketosis continues for long periods of time, serious damage to the liver and kidneys can occur, which is why most low-carbohydrate, or ketogenic diets recommend only short-term use, typically 14 days.

    I don't know where to start.
    Okay, I'll start with the assumption that keto is high protein. No, it's not, it's moderate protein compared with standard BB diets. The dangers of protein to the kidneys would apply far more to a 40/40/20 diet than to a keto one. If they applied. But they don't. People with damaged kidneys can not tolerate high levels of protein. So some "experts" have extrapolated this to mean that high levels of protein can damage healthy kidneys. Except there has not been one single case of this ever, in the history of recorded medicine.
    Most keto diets do not recommend 14 days or less, that's the classic way to do it wrong. Most low carb diets recommend making it a lifestyle.
    And again, where is the evidence that ketones do any damage to liver or kidneys or any other organ? Not a single case. The closest to damage from a low carb diet comes from the odd nutcase who tries to combine keto with no liquid, which does put stress on the kidney (just like any other diet which does not include liquid) but because keto is slightly diuretic, you'll see the effects a little quicker.

    There are people who try that? I don't see how. Keto makes me thirsty and will often drink constantly as long as my glass of water is full.
