Very high levels of ketones make your blood more acidic and overburden your kidneys. Yes
Normally your body burns carbohydrates for fuel. When you drastically cut carbs, the body goes into a metabolic state called ketosis, and it begins to burn its own fat for fuel. When your fat stores become a primary energy source, you may lose weight. 1 Osteoporosis and kidney stones. 2  When you're on a high-protein diet, you may urinate more calcium than normal. 3  There are conflicting reports, but some experts think this could make osteoporosis and kidney stones more likely. Ketosis /kɨˈtoʊsɨs/ is a metabolic state where most of the body's energy supply comes from ketone bodies in the blood, in contrast to a state of glycolysis where blood glucose provides most of the energy.  Ketosis Effects on the Kidneys. Very high levels of ketones make your blood more acidic and overburden your kidneys. Medical News Today reports that one of the side effects of a ketogenic diet is the formation of kidney stones. In processing higher amounts of protein, your kidneys work hard and are forced to excrete more sodium, calcium and potassium, as well as filter more of the byproducts of protein metabolism. Ketosis happens when your body resorts to fat for energy after your stored carbohydrates have been burned out. It often occurs when people fast and exercise. But most commonly, ketosis occurs in people who eat low-carb, high-protein diets, which are also called ketogenic diets. There’s some evidence that ketosis can tax your kidneys, leading to kidney stones and low blood pressure. In diabetics, a variant of ketosis can be fatal Ketosis will take place when the body needs energy and there is not sufficient glucose available for the body. This can typically happen when the body is lacking insulin and blood glucose levels become high. Other causes can be the result of being on a low carb diet. Ketosis is a state the body may find itself in either as a result of raised blood glucose levels or as a part of low carb dieting. Low levels of ketosis is perfectly normal. 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. 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. 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. Excess ketones are then eliminated during urination. Ketosis occurs when the amount of carbohydrate fuel-the fuel that is needed to run the body-drops below a critical level, forcing the body to turn first to protein and then to fat reserves to do the work carbohydrates normally do. 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. 11/26/10 - 371 1/1/11 - 348. 11/26/10 - 371. 1/1/11 - 348. 11-29-2010, 11:36 AM #2.

Ketosis is a state the body goes into if it needs to break down body fat for energy. The state is marked by raised levels of ketones in the blood which can be used by the body as fuel. Ketones which are not used for fuel are excreted out of the body via the kidneys and the urine. Ketosis is a state the body may find itself in either as a result of raised blood glucose levels or as a part of low carb dieting. Low levels of ketosis is perfectly normal.
