This article is about a dietary therapy for epilepsy. For information on ketogenic diets as a lifestyle choice or for weight loss, see Low-carbohydrate diet and No-carbohydrate diet. The ketogenic diet is a high-fat, adequate-protein, low-carbohydrate diet that in medicine is used primarily to treat difficult-to-control (refractory) epilepsy in children. The diet forces the body to burn fats rather than carbohydrates. Normally, the carbohydrates contained in food are converted into glucose, which is then transported around the body and is particularly important in fueling brain-function. However, if there is very little carbohydrate in the diet, the liver converts fat into fatty acids and ketone bodies. The ketone bodies pass into the brain and replace glucose as an energy source. An elevated level of ketone bodies in the blood, a state known as ketosis, leads to a reduction in the frequency of epileptic seizures. Almost half of children, and young people, with epilepsy who have tried some form of this diet saw the number of seizures drop by at least half, and the effect persists even after discontinuing the diet. There is some evidence that adults with epilepsy may benefit from the diet, and that a less strict regimen, such as a modified Atkins diet, is similarly effective. The most common adverse effect is constipation, affecting about 30% of patients—this was due to fluid restriction, which was once a feature of the diet, but this led to increased risk of kidney stones, and is no longer considered beneficial. The original therapeutic diet for paediatric epilepsy provides just enough protein for body growth and repair, and sufficient calories[Note 1] to maintain the correct weight for age and height. The classic therapeutic ketogenic diet was develope Continue reading >>
Does A Ketogenic Diet Cause Kidney Stones?
I remember the first time I learned about the connection between a diet high in sugar and gout, kidney stones and heart disease. I was reading a book (I don’t remember which one) that was laying out the evidence that showed a clear link between sugar consumption and those diseases and it immediately peaked my interest because I didn’t know that gout was still a thing. I had only heard of old French monarchs having it and honestly didn’t know it was still around until just a few weeks before reading that book. Just a few weeks prior to reading that, I learned that my son’s Father in Law had gout and occasional kidney stones and as I read that passage in the book, I thought about calling him and telling him what I read. I decided against it and figured I would bring it up the next time I saw him at church. Unfortunately, before I ever got a chance to say anything to him, he had a heart attack. He’s fine now but I have always felt bad I didn’t immediately make a call. I realize it wouldn’t have done much given how quickly it all happened but still, I should have said something. Since then, probably the most common question I get about the ketogenic diet is whether or not it will cause kidney stones and there is definitely a connection but possibly not how you think. First let’s go over how kidney stones are formed. How Kidney Stones are Formed At one point in time it was thought that uric acid was produced solely from the breakdown of purines found in foods like liver, pork, mushrooms, anchovies, mackerel and dried beans which is why most patients that were susceptible to kidney stones or gout were put on a low purine diet. Unfortunately those diets didn’t work too well and almost always had to be supplemented with additional medications that controlled t Continue reading >>
Clearing Up Kidney Confusion: Part Deux
It’s funny how our mental state really affects how we write and what we are interested in. When I wrote the introduction to this piece I was just getting settled into our new place in Santa Fe, NM and was looking at over a month at home to work and write. Then a number of wacky events happened and I’ve been home about 7 days out of the last month and I’ve only made it about 70 pages into Kon-Tiki. Ouch. Now I’m home for 8 days and will then be gone for a project that will take me completely off the grid for nearly 3 weeks. No phone, email…nada. When I sat down to do this kidney piece it was with a mindset that I had a ton of time and could really sink my teeth into it. Now I’m time crunched and anxious that I will get it done at all! Up front here I’d like to thank Mat “The Kraken” Lalonde with his help on some literature for this piece. Any inaccuracies however are my own tomfoolery. If I wanted to cut to the chase I could boil this whole thing down to the following: 1-Dietary protein DOES NOT CAUSE KIDNEY DAMAGE. 2-Chronically elevated BLOOD GLUCOSE levels DO cause kidney damage. 3-Dietary fructose REALLY causes kidney damage. 4-Many kidney issues have either a hyperinsulinemic characteristic, an autoimmune characteristic, and or a combination of autoimmunity or hyperinsulinism. A standard, low-ish carb paleo diet can fix most of these issues. 5-For serious kidney damage a low-protein, ketogenic diet can be remarkably therapeutic. 6-If you get kidney stones that are from oxalates, reduce your green veggie intake (spinach for example) and have other types of veggies. 7-If you get kidney stones that are from urate salts, you are likely NOT following a low-ish carb paleo diet, you likely have insulin resistance and your liver is not processing uric acid Continue reading >>
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 site of endogenous ketone production, so taking exogenous ketones with KETO//OS would provide another source besides the liver to make ketones. Remember, KETO//OS and exogenous ketones are a source of calories; so be sure to consider it in your daily goals. KETO//OS and exogenous ketone supplementation is not hard on the liver.

Dangers Of Zero-carb Diets, Iv: Kidney Stones
Kidney stones are a frequent occurrence on the ketogenic diet for epilepsy. [1, 2, 3] About 1 in 20 children on the ketogenic diet develop kidney stones per year, compared with one in several thousand among the general population.  On children who follow the ketogenic diet for six years, the incidence of kidney stones is about 25% . A 100-fold odds ratio is hardly ever seen in medicine. There must be some fundamental cause of kidney stones that is dramatically promoted by clinical ketogenic diets. Just over half of ketogenic diet kidney stones are composed of uric acid and just under half of calcium oxalate mixed with calcium phosphate or uric acid. Among the general public, about 85% of stones are calcium oxalate mixes and about 10% are uric acid. So, roughly speaking, uric acid kidney stones are 500-fold more frequent on the ketogenic diet and calcium oxalate stones are 50-fold more frequent. Causes are Poorly Understood In the nephrology literature, kidney stones are a rather mysterious condition. Wikipedia has a summary of the reasons offered in the literature for high stone formation on the ketogenic diet : Kidney stone formation (nephrolithiasis) is associated with the diet for four reasons: Excess calcium in the urine (hypercalciuria) occurs due to increased bone demineralisation with acidosis. Bones are mainly composed of calcium phosphate. The phosphate reacts with the acid, and the calcium is excreted by the kidneys. Hypocitraturia: the urine has an abnormally low concentration of citrate, which normally helps to dissolve free calcium. The urine has a low pH, which stops uric acid from dissolving, leading to crystals that act as a nidus for calcium stone formation. Many institutions traditionally restricted the water intake of patients on the diet to Continue reading >>
How Low-carb Diets May Be Causing More Kidney Stones
Like many busy people, David Crossley often used to find himself so wrapped up in his working day that he would go without lunch, and often barely stopped for a cup of tea. In fact, David, 63, a musculoskeletal therapist from Birmingham, admits: 'I would often be so busy at the clinic that I'd forget to drink any liquid at all, other than the odd cup of tea or coffee. It had been the same way for years - although I would drink more water at weekends.' Last year, this habit caught up with him. He noticed a vague ache in his abdomen, stretching around to his back. 'It wasn't agonising but it just didn't feel quite right, so I went to the GP,' he says. 'As I had some bloating, he sent me for an ultrasound.' This revealed two large stones in his right kidney - a direct result, his doctors believe, of his low fluid intake. A CT scan showed that the stones were so large (6 mm across) they could not be passed naturally, and he needed surgery. One in ten of us will develop a kidney stone, and the numbers are rising dramatically. They are the result of waste products in the blood forming crystals inside the kidneys, which eventually build up into a solid lump. They can be excruciatingly painful - on a level, say experts, with childbirth. The stones often remain symptomless while they're in the kidney. They start causing pain - known as renal colic - once they travel down the ureter, the narrow tube that carries urine from the kidney to the bladder. 'Renal colic is caused by the stone suddenly blocking the ureter,' says Mr Leye Ajayi, consultant urological surgeon at the Hospital of St John & St Elizabeth, London. The pain often comes on suddenly and can cause the patient to 'writhe around in agony', he adds. The pain can be intense enough to cause nausea and vomiting. Once on th Continue reading >>
High Protein Diet Brings Risk Of Kidney Stones
Diets heavy on foods that are high in protein and low in carbohydrates can increase the risk of kidney stones and reduce the body's ability to absorb calcium after just six weeks. These findings from a new study come at a time when an increasing number of Americans, seduced by anecdotal accounts of fast weight loss, are turning to low carbohydrate, high protein diets. Popularised by Dr Robert Atkins, these diets are having a revival after a recent cover story in the New York Times Magazine said that relying on diets heavy in carbohydrates and low fat products has caused people to hold on to fat, explaining a rising incidence of obesity and perhaps diabetes. Although low carbohydrate, high protein diets result in weight loss in the short term, they are less successful in the long term and may even be hazardous to health, researchers have warned. Protein rich foods can be high in fat, which increases the risk of heart disease and type 2 diabetes. Diets heavy in foods with low levels of carbohydrate, such as fruit and vegetables, can also leave the body hungry for essential vitamins and minerals, and insufficient glucose from carbohydrates, the body's preferred fuel source, can lead to fatigue and dizziness (American Journal of Kidney Diseases 2002;40:265-74). The researchers, led by Dr Shalini Reddy from the University of Chicago, found that six weeks on a low carbohydrate, high protein diet increased the acid load to the kidneys, raising the risk of kidney stones. Animal protein has been shown to boost urinary excretion of oxalate, a compound that combines with calcium and other compounds to form kidney stones. The new study included 10 healthy adults aged 21 to 52 who ate their usual diet for two weeks, then a low carbohydrate, high protein diet for two weeks, and final Continue reading >>

Getting To Know Ketones
People with diabetes, particularly those with Type 1 diabetes, have been at least vaguely aware of the word ketones for a long time. With the recent resurgence of popular interest in low-carbohydrate diets, however, just about everyone seems to be talking about ketones these days. But does anyone really know what ketones are? Are they a danger to your health (as in diabetic ketoacidosis), or a sign that you have lowered your carbohydrate intake enough to cause weight loss (as some people who follow low-carbohydrate diets believe)? What are ketones? Ketones are end-products of fat metabolism in the body. That is, they are formed when fat is burned for energy by the muscles. Chemically, they are acids known as ketone bodies, and there are three types: beta-hydroxybutyric acid, aceto-acetic acid, and acetone. But you don’t have to be a chemist to understand what role they play in the body. To get to know ketones, it’s helpful to understand how your body burns fuel. A simple analogy is that of an automobile. For a car engine to run, the engine must burn fuel (gasoline), and when the fuel is burned, exhaust (carbon monoxide) is created. The carbon monoxide is the end-product of gasoline combustion. Your body also has an engine that must burn fuel to operate. The engine is muscle, and the fuel is fat, carbohydrate (glucose), and, in certain conditions, protein. When fat is burned, the “exhaust” is ketones, and when glucose is burned, the “exhaust” is lactic acid. Fat is more desirable as a fuel than glucose because there are more calories in a gram of fat (9 calories per gram) than there are in a gram of glucose (4 calories per gram), so you get more energy per gram of fat burned. In a sense, you could call fat a high-test fuel. But there is one catch to burning f Continue reading >>
Does Diabetes Increase My Risk For Developing Kidney Stones?
What’s the connection between diabetes and kidney stones? Diabetes is a condition in which your body doesn’t produce enough insulin or can’t use it properly. Insulin is crucial to regulating blood sugar levels. High blood sugar can cause problems in any part of your body, including your kidneys. If you have type 2 diabetes, you may have very acidic urine. That increases your risk for developing kidney stones. Kidney stones form when you have high concentrations of certain substances in your urine. Some kidney stones form from excess calcium oxalate. Others form from struvite, uric acid, or cysteine. The stones can travel from your kidney through your urinary tract. Small stones may pass through your body and out in your urine with little or no pain. Larger stones may cause a great deal of pain. They can even get lodged in your urinary tract. That can block urine flow and cause infection or bleeding. Other symptoms of kidney stones include: back or abdominal pain nausea vomiting If you experience severe symptoms of kidney stones, see your doctor. Your doctor may suspect kidney stones based on your symptoms. Urinalysis, blood tests, and imaging tests may be needed to confirm the diagnosis. Anyone can form a kidney stone. In the United States, almost 9 percent of people have had at least one kidney stone, according to the National Institute of Diabetes and Digestive and Kidney Diseases. In addition to diabetes, other risk factors for kidney stones include: obesity diet high in animal protein family history of kidney stones diseases and conditions that affect the kidneys diseases and conditions that affect the amount of calcium and certain acids in your body urinary tract disorders or chronic inflammation of the bowel Certain medications can also put you at higher ris Continue reading >>
Ketosis – What Is That All About?
What’s it all about? Is it good for you? Is it bad for you? What’s it like? How do I ‘do’ ketosis? How do I know I’m in ketosis? The questions everyone who’s Banting wants the answers to. Ketosis, in chef speak, is quite simply a state your body enters once it has been deprived of glucose. Your body switches to burning fat for energy (stored fat or fat that you have eaten) instead of glucose. A side-effect of that process is the release of ketone bodies into the blood stream. When you’re starved of glucose, your body has no choice but to burn fat for fuel, so it needs little explanation as to why ketosis works at melting fat like a blow heater on an ice sculpture. Ketosis comes with some added extras, namely a commonly noted sense of euphoria or lucidity and increased energy levels. A downside includes toothbrush-proof halitosis, which stems from the secretion of ammonia through the lungs as a side effect of burning all that fat. Some people on low-carb diets have reported kidney stones, gallstones and a number of other ailments. Scientific research on both sides of this debate is being done all the time, but in our experience from talking to the members of our community and tracking their data, it is generally a case of what was done before they started Banting and not Banting itself. But, this post isn’t here to debate that, it serves as a ‘how to’ and not as a ‘you should’. Eat more buttery or creamy sauce on your steak and eat less steak. Your body can convert protein into glucose so too much meat will hinder your progress. What doIdo? Theoretically it is very easy. Avoid anything with high carbs in it. If you’re not sure what those might be, consult the Real Meal Revolution ‘Red List’. Even dipping your toe into the red list will ruin Continue reading >>
All About Kidney Stones
There are three things related to nutrition and lifestyle that I never want to experience: A cardiac catheterization A Cinnamon Toast Crunch-induced coma A kidney stone Needless to say, I was excited to write this article. What are kidney stones? Kidneys make clean blood by eliminating wastes. For instance, if you eat a can of soup with lots of salt, the kidney will excrete more salt to balance out levels in the body. If you eat a big steak, more urea will be excreted in the urine. If the body is unable to eliminate these wastes, you get sick. (Here’s a primer on the urinary system.) Our kidneys eliminate waste products through urine, and when there is excessive waste or not enough fluid volume, urine becomes supersaturated and a stone can form. Stones can be tiny like a grain of sand or big like a golf ball. Stones can hang out in the kidneys for years without obstructing any tubing. But when a stone obstructs the ureter, serious pain follows (it’s been said that kidney stones are the worst pain imaginable). The pain can stop/start as the stone heads to the bladder. The bladder tunnel is where most stones get hung up. Since stones may have sharp edges, they can draw blood into the urine. Kidney stone types There are four main types of kidney stones: Calcium-containing stones – these make up a majority, nearly 75% of stones Uric acid stones – these make up about 10% of stones Struvite (infected) stones – these make up about 10% of stones and form after an infection in the urinary tract Cystine stones – these are stones that form from the amino acid cystine, the most uncommon The table below shows the composition, frequency, and causes of kidney stones, aka nephrolithiasis (nephro = kidney; lith = stone). Why are kidney stones important? Kidney stones are inc Continue reading >>
Does High Protein Intake Cause Kidney Failure?
The role of protein in muscle repair and development is evident. Our body metabolizes a large amount of protein throughout a day. Some research claims that excess amount of protein metabolism can affect the kidney function. So far, there is no direct relation to excess protein intake and kidney damage. However, there are few hypothesis that points out the effect of excess protein on kidney function. Important role of Protein Some important role of protein in our body includes Make hormones Repair and heal tissues Produce antibodies and enzymes Fluid and electrolytes balance Foods high in protein includes eggs, chicken, cottage cheese, milk, peanuts, etc. In what ways an excess protein can affect kidney function? (Src) Metabolism of protein in our body produces some toxic element like ketones as a byproduct. Most of the time, ketones are eliminated by the kidneys. But sometimes they are left behind. These ketones can hamper the kidney function. It can also cause other complications such as dehydration, dizziness, fatigue, heart palpitations, and bad breath. Let see on what basis this is concluded. The Kidney function is measured by Glomerular Filtration Rate ( GFR). It determines how well the kidney is working or filtering the blood. Research have shown that excess protein filtration can affect the GFR rates. Also known as hyperfiltration. Over the long term, hyperfiltration may lead to acute renal failure. CKD (Chronic Kidney Disease) (Src) The various Scientific report indicates that restriction of dietary protein in CKD patient can reduce albuminuria (albumin protein found in urine) and uraemic symptoms. Here are some CKD diseases that is closely related to the dietary protein intake. Proteinuria When kidneys are not functioning well, they cannot filter protein proper Continue reading >>
How To Prevent Kidney Stones Naturally
This is a guest post by Laura Schoenfeld, a Registered Dietitian with a Master’s degree in Public Health, and staff nutritionist and content manager for ChrisKresser.com. You can learn more about Laura by checking out her blog or visiting her on Facebook. Anyone who’s had a kidney stone will tell you that they’re one of the worst medical problems you can ever experience. Kidney stones are a common and painful chronic condition seen in otherwise “healthy” patients, and one of the most common disorders of the urinary tract. About a million people in the United States are treated for kidney stones each year, and the prevalence in adult men is almost 12% and around 6% in adult women. (1) Stones are most common in caucasian adults between the ages of 20 and 50, and once someone develops a stone, they are far more likely to develop another stone in the future. Like most chronic diseases, the incidence of kidney stones has been increasing over the past 30 years. (2) This is likely due to the variety of dietary and lifestyle changes we’ve made as Americans which aren’t conducive to good health. What are Kidney Stones? Stones can be formed from a variety of substances, but the most common stones are made of calcium and oxalate that has crystalized in the urinary tract. Other types of stones include struvite, uric acid and cystine. While stones themselves are painful enough, they can lead to more serious conditions such as obstruction of the urinary tract, permanent damage to the kidneys, and even life-threatening infections. I’ve seen patients in the hospital who have come in with necrotic kidneys due to obstruction from a stone, so this can become a serious condition if not managed properly. Conventional medical professionals take a multi-pronged approach to tre Continue reading >>
Does Ketosis Cause Kidney Damage?
The ‘Lean for Life’ program is mildly ketotic, and only for a brief portion of the program. It has not been associated with kidney damage or disease in individuals who have normally functioning kidneys. Concerns regarding undue stress on the kidneys are often aimed at very low carbohydrate, very high protein ketogenic diets. Few studies have shown any actual damage, however. (Note: Although the Weight Loss portion of the ‘Lean for Life’ program is mildly ketogenic, it is not considered to be exceptionally “high protein” for most individuals.) Dietary ketosis is among the most maligned and misunderstood concepts in nutrition medicine. Particularly among researchers who don’t actually treat patients, ketosis (the presence of ketone bodies in the urine) is often confused with ketoacidosis, which is a life-threatening build-up of ketone bodies due to muscle wasting and dehydration as in states of shock or uncontrolled Type 1 diabetes. In the Type 1 diabetic, the absence of insulin leads to a toxic build-up of blood glucose and an extreme break-down of fat and muscle tissue. This condition doesn’t occur in individuals who have even a small amount of insulin, whether from natural production or artificially administered. Whereas patients in ketoacidosis are closely monitored in Intensive Care Units, individuals in ketosis are amongst the healthy, active population. Dietary ketosis is a natural adjustment to the body’s reduced intake of carbohydrates as the body shifts its primary source of energy from carbohydrates to stored fat. The presence of insulin keeps ketone production in check so that a mild, beneficial ketosis is achieved. Blood glucose levels are stabilized within a normal range and there is no break-down of healthy muscle tissue. It would be diffi Continue reading >>
Can Keto//os Cause Kidney Stones?
The use of exogenous ketones is a new and novel technology. So the safety profile of a ketone supplement like KETO//OS begins to emerge as more research is being done. Often people are concerned about kidney or liver health when it comes to exogenous ketones. What the studies are actually finding, is that ketones, specifically beta hydroxybutyrate (BHB), is actually beneficial to the health of our liver and kidneys. There are also many other benefits of taking ketones as well. The risk of kidney stones can be a concern, as we know there is a small risk from a ketogenic diet standpoint. However, potassium supplementation decreases that risk of getting kidney stones substantially. Exogenous ketone and potassium supplementation while following a ketogenic diet, is an effective combination. To learn more about, and order exogenous ketones, go to the Prüvit online store.
