Ketones, Ketosis, And Ketogenic Diets
An understanding of ketones and ketosis is essential for understanding how some high protein-low carbohydrate diets (also called Ketogenic Diets) such as Atkins diet works. Ketones are mild acids, a sort of reserve fuel released from burned fats for survival under conditions of starvation. When we go without food for even a few days our bodies begin living off our stored fats, and these release ketones. During ketosis, the body switches from using glucose for energy (sufficient dietary carbohydrates are not available) to using fat. Fatty acids are then released into the bloodstream and converted into ketones. The ketones themselves are produced by the metabolism of fat. Ketosis refers to the process of the conversion. The ketones are used by your muscles, your brain, and other organs as an energy source. 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. 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. Many nutritionists caution their patients-especially women in the early stages of pregnancy-against following them at all. Fasters experience a sensation of improved well-being a Continue reading >>
The Liver & Blood Sugar
During a meal, your liver stores sugar for later. When you’re not eating, the liver supplies sugar by turning glycogen into glucose in a process called glycogenolysis. The liver both stores and produces sugar… The liver acts as the body’s glucose (or fuel) reservoir, and helps to keep your circulating blood sugar levels and other body fuels steady and constant. The liver both stores and manufactures glucose depending upon the body’s need. The need to store or release glucose is primarily signaled by the hormones insulin and glucagon. During a meal, your liver will store sugar, or glucose, as glycogen for a later time when your body needs it. The high levels of insulin and suppressed levels of glucagon during a meal promote the storage of glucose as glycogen. The liver makes sugar when you need it…. When you’re not eating – especially overnight or between meals, the body has to make its own sugar. The liver supplies sugar or glucose by turning glycogen into glucose in a process called glycogenolysis. The liver also can manufacture necessary sugar or glucose by harvesting amino acids, waste products and fat byproducts. This process is called gluconeogenesis. When your body’s glycogen storage is running low, the body starts to conserve the sugar supplies for the organs that always require sugar. These include: the brain, red blood cells and parts of the kidney. To supplement the limited sugar supply, the liver makes alternative fuels called ketones from fats. This process is called ketogenesis. The hormone signal for ketogenesis to begin is a low level of insulin. Ketones are burned as fuel by muscle and other body organs. And the sugar is saved for the organs that need it. The terms “gluconeogenesis, glycogenolysis and ketogenesis” may seem like compli Continue reading >>

A A A Urine Test Test Overview A urine test checks different components of urine, a waste product made by the kidneys. A regular urine test may be done to help find the cause of symptoms. The test can give information about your health and problems you may have. The kidneys take out waste material, minerals, fluids, and other substances from the blood to be passed in the urine. Urine has hundreds of different body wastes. What you eat and drink, how much you exercise, and how well your kidneys work can affect what is in your urine. More than 100 different tests can be done on urine. A regular urinalysis often includes the following tests: Color. Many things affect urine color, including fluid balance, diet, medicines, and diseases. How dark or light the color is tells you how much water is in it. Vitamin B supplements can turn urine bright yellow. Some medicines, blackberries, beets, rhubarb, or blood in the urine can turn urine red-brown. Clarity. Urine is normally clear. Bacteria, blood, sperm, crystals, or mucus can make urine look cloudy. Odor. Urine does not smell very strong, but it has a slightly "nutty" odor. Some diseases cause a change in the odor of urine. For example, an infection with E. coli bacteria can cause a bad odor, while diabetes or starvation can cause a sweet, fruity odor. Specific gravity. This checks the amount of substances in the urine. It also shows how well the kidneys balance the amount of water in urine. The higher the specific gravity, the more solid material is in the urine. When you drink a lot of fluid, your kidneys make urine with a high amount of water in it, which has a low specific gravity. When you do not drink fluids, your kidneys make urine with a small amount of water in it, which has a high specific gravity. pH. The pH is Continue reading >>
Lupus And Kidney Disease: What You Should Know About Lupus Nephritis (lupus Kidney Disease)
Adapted from a presentation at the SLE Workshop at Hospital for Special Surgery Introduction At this session of the SLE Workshop at HSS, Dr. Kyriakos Kirou presented his expertise on the diagnosis, symptoms, treatments, and research related to lupus and kidney involvement, including lupus nephritis (LN). Dr. Kirou is an assistant attending physician at HSS and the co-director of the Mary Kirkland Center for Lupus Care. When presenting, Dr. Kirou emphasized that the purpose of his presentation is to educate patients about lupus and its interaction with the kidney and should not be used as therapeutic advice. He stressed that when patients need to make a decision about their own specific care, they should consult their own rheumatologist. It is important to recognize that there’s no “one fits all” therapy. Dr. Kirou discussed how lupus can affect the kidney and cause the disease known as lupus nephritis (LN). He also discussed tests that are used for diagnosis, as well as available therapies. He also spoke about the necessary lifestyle changes that LN patients may have to adopt after their diagnosis of LN to minimize harm in their bodies. First, it is important to understand how the kidney functions, what happens when someone with lupus has problems with their kidneys, and how they can go about dealing with the situation. Background Information Lupus:Lupus is a chronic and autoimmune disease that affects several parts of the body, including joints, blood, skin, and kidneys. The immune system of those with lupus does not function properly. Lupus creates autoantibodies that fight and damage the cells, tissues, and body organs. When they are present, they can likely lead to disease. Kidney: The kidney is a bean-shaped, fist-sized organ that helps cleans the body from a Continue reading >>
Tweet 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. However, high levels of ketosis in the short term can be serious and the long term effects of regular moderate ketosis are only partially known at the moment. What is ketosis? 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. Is ketosis the same as ketoacidosis? There is often confusion as to the difference between ketosis and ketoacidosis. Ketosis is the state whereby the body is producing ketones. In ketosis, the level of ketones in the blood can be anything between normal to very high. Diabetic ketoacidosis, also known as DKA, only describes the state in which the level of ketones is either high or very high. In ketoacidosis, the amount of ketones in the blood is sufficient to turn the blood acidic, which is a dangerous medical state. When does ketosis occur? 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. A low level of carbohydrate will lead to low levels of insulin, and therefore the body will produce ketones which do not rely on insulin to get into and fuel the body’s cells. A further cause of ketosis, less relevant to people with diabetes, is a result of excessive alcohol consumption. Is ketosis dangerous? The NHS describes ketosis as a pote Continue reading >>
Five Things To Know About Ketones
If you live with diabetes, you have probably heard that ketones are something to watch out for. That they have something to do with the dreaded diabetic ketoacidosis (DKA). But do you really understand what ketones are and why they happen? It’s scary to think about, sure. But it’s also very important to be in the know about ketones and to be prepared. 1) What are ketones? If there isn’t enough insulin in your system, you can’t turn glucose into energy. So your body starts breaking down body fat. Ketones are a chemical by-product of this process. This can occur when people with type 1 diabetes don’t take insulin for long periods of time, when insulin pumps fail to deliver insulin and the wearer does not monitor blood glucose, or during serious illness (in type 1 or type 2) when insulin doses are missed or not increased appropriately for the stress of illness. Ketones can happen to anyone with diabetes, but the condition is more common in people with type 1. 2) Why are ketones dangerous? Ketones upset the chemical balance of your blood and, if left untreated, can poison the body. Your body cannot tolerate large amounts of ketones and will try to get rid of them through the urine. Eventually they build up in the blood. The presence of ketones could be a sign that you are experiencing, or will soon develop, diabetic ketoacidosis (DKA)—a life-threatening medical emergency. 3) When should I test for ketones, and how? There are several situations in which it is a good idea to check for ketones, usually every four to six hours. Talk to your doctor to know what makes the most sense for you and your diabetes management plan. Your blood glucose is more than 300 mg/dl (or a level recommended by your doctor) You feel nauseated, are vomiting or have abdominal pain You are Continue reading >>
Of The Keto Diet?
There are many awesome benefits that come with adopting a low-carb ketogenic diet, such as weight loss, decreased cravings and even possibly reduce disease risks. With that being said, it’s also good to talk about possible ketosis side-effects when ingesting these specific ketone supplements, so you know fully what to expect when you get started on this mission. If you’ve already heard about some of the side-effects that come with this special diet and are starting to freak out, don’t panic. We’re going to break down everything you need to know when it comes to what your body will experience when using these supplements for the first time. It’s important to remember, not everyone experiences side-effects when starting a ketogenic diet and thankfully, the symptoms are all very temporary and it can pass very quickly. It varies with the individual, but just to make sure all your bases are covered, we’re going to break down each possible side effect that you could possibly experience. 1. Flu Symptoms Within the first 2-4 days of beginning this diet, a common side-effect is known as the “ketosis flu” or “induction flu” because it mimics the symptoms of the actual flu. This means you might experience: Headaches Lethargy Lack of motivation Brain fog or confusion Irritability Although these symptoms typically go away completely within a few days, they are also completely avoidable if you stay very hydrated and increase your salt intake and like always, be sure you're eating enough fat. 2. Dizzyness & Drowsiness As you start dumping water, you'll lose minerals such as salt, potassium and magnesium. Having lower levels of these minerals will make you tired, lightheaded or dizzy. You may also experience muscle cramps, headaches and skin itchiness. Fatigue Continue reading >>
Could A High-fat, Low-carb Diet Someday Replace Dialysis?
MORE A type of low-carb, high-fat diet that's typically used to manage seizures for children with epilepsy could reverse kidney disease in Type 1 and Type 2 diabetics, a new animal study suggests. If successful in humans, the so-called ketogenic diet could have the potential to replace dialysis, which is a procedure that artificially filters blood in place of a damaged or failed kidney, said study researcher Charles Mobbs, professor of neuroscience and geriatrics and palliative care medicine at Mount Sinai School of Medicine in New York City. "I speculate that this may be useful to completely cure diabetic kidney failure , and I hope that it's possible," Mobbs told MyHealthNewsDaily. "If it's possible, we can potentially not require dialysis. That's a big deal." However, a lot more research in mice is needed before any studies can be done in humans, Mobbs said, let alone determine if the diet can reverse advanced kidney disease in humans, he said. "That's the first thing we want to establish in mice: Can we truly reset the clock? Can we completely correct the [kidney] impairments?" Mobbs said. Other experts say the finding is promising for Type 1 and Type 2 diabetics with earlier-stage kidney disease, but more research must be done to provide evidence that the diet can make an impact on end-stage kidney disease , or kidney failure. Type 1 diabetes is a chronic disease that occurs when the pancreas cannot produce enough insulin (needed to move blood sugar into cells for energy) to control blood sugar levels, according to the National Institutes of Health. Type 2 diabetes occurs when the body becomes resistant to insulin, leading to high blood sugar levels. Overweight and obesity, a sedentary lifestyle and poor diet are risk factors for Type 2 diabetes, according to the N Continue reading >>
Why Do Ketones Spill Over Into Urine?
Dear Dr. Wilson, The body is a pretty finely tuned instrument, sugar is regulated tightly. Why when we are burning ketones during weight loss do they spill over to the urine? I would have thought that they would be produced as and when needed and not be wasted. Dr Wilson’s Response: This is an excellent question because the issue of ketosis even confuses many physicians. Ketosis is a normal physiological response to starvation. Our primitive ancestors often went for long periods of time without eating. If you fail to eat for a period of time your body switches from using glucose for energy to using fats. Triglycerides are then broken down into ketone bodies in your liver and these ketones can be used for energy throughout your body including your brain. If the ketone levels in your blood rise high enough some of them will be filtered by your kidney’s and end up in the urine. When doctors think about ketosis the first thing they think about is diabetic ketoacidosis, a potential deadly complication of type I diabetes. If someone with this form of diabetes doesn’t have enough insulin in their body to allow glucose to be used by cells, their body will start to break down fat to use for energy. Unlike starvation ketosis, this process is pathological, not physiological. Without adequate treatment patients with diabetic ketoacidosis can die whereas the ketosis associated with starvation is completely benign. The kidney’s tend to clear excessive ketones when you are starving because high levels of ketones can produce acidosis, a potentially unhealthy state. Thus spilling some ketones in the urine is Mother Nature’s escape valve to prevent excessive elevation of ketones leading to acidosis. In patients with diabetic ketoacidosis their body is solely relying on fat for Continue reading >>
Are Ketones In Urine During Pregnancy A Problem
Most women are flustered by frequent urine and blood tests for monitoring healthy pregnancy. Routine checkups paired with dietary restrictions are not a pleasant experience for any women. However, any condition should not be overlooked during those laborious nine months of gestation. If your urine report indicates presence of ketones, then stop and read below! Although ketones in urine during pregnancy may not lead to complications in pregnancy, here’s some food for thought: What are ketones? Ketones are acid bodies which are produced when fat is broken down by the body instead of carbohydrates to keep the body working. Causes This usually happens, when there is shortage of carbohydrates in body, probably when one has not eaten for a long time. Secondly, if the body is unable to obtain glucose from blood, then the liver breaks down fats which produces ketones. The lower rate of insulin in blood, like when suffering from diabetes or pancreatic disorders may not be producing sufficient quantities of insulin to break down sugar/glucose from the food we eat in usable form. Starvation: If carbohydrates are not provided to the body and the fat is continuously broken down to obtain energy, then resulting ketones keep accumulating which then become detectable in blood and urine. Dehydration Low-carbohydrate diet: When pregnant, one needs approx 300 calories more per baby. If enough calories are not being provided to body, then liver breaks down fat or protein to obtain energy. Eating disorders: Anorexia Nervosa, Bulimia Nervosa Metabolic disorders Stress Symptoms vomiting or nausea excessive sweating weakness fatigue headache dizziness bad breath abdominal pain feeling thirsty all the time If you experience any of the above symptoms during pregnancy, its sensible to inform yo Continue reading >>
Abnormal Contents Of Urine
Normally, urine contains water and wastes, such as urea, uric acid, creatinine, and some ions. However, some of these substances may be abnormally elevated, which usually indicates that something is wrong with the body. The following are some of the abnormal constituents of urine and some possible causes. Albumin Albumin is a type of protein, which is a normal component of plasma—the fluid component of blood. When albumin is found to be excessive in the urine, it may indicate that the tiny filtering units in the kidney, called nephrons, are damaged or destroyed. Elevated albumin in the urine is termed albuminuria. Bilrubin Bilirubin, when modified by the kidneys, contributes to the classical yellow color of urine. It is a byproduct that results from the breakdown of hemoglobin—the red pigment in red blood cells. When levels of bilirubin in urine is above normal, the condition is called bilirubinuria. This may indicate liver disease or obstructive biliary disease. Glucose The presence of glucose or blood sugar in urine is called glucosuria. It may indicate that the person has diabetes. Ketone bodies The presence of ketone bodies in the urine may indicate diabetes or anorexia. It may also be elevated during fasting and starvation. Microbes The presence of microorganisms, such as bacteria or fungus may indicate urinary tract infection. Blood The red blood cells in blood should not be found in urine because they are too large to pass through the nephrons. Hematuria is the clinical term used when red blood cells are present in the urine. It may indicate damage to the kidney, such as in renal or kidney disease. Sometimes, blood may be present because of the presence of kidney stones. White blood cells When white blood cells are present in the urine, it may indicate infect Continue reading >>
Test Overview A ketone test checks for ketones in your blood or urine. Ketones are substances that are made when the body breaks down fat for energy. Normally, your body gets the energy it needs from carbohydrate in your diet. But stored fat is broken down and ketones are made if your diet does not contain enough carbohydrate to supply the body with sugar (glucose) for energy or if your body can't use blood sugar (glucose) properly. Ketones can be tested in a laboratory. Or you can test for ketones anywhere you may be by using home blood or urine tests. Continue reading >>
Is Keto And Ketosis Safe?
The ketogenic diet and ketosis are safe. Not only are they safe, but they are useful in helping people with many different conditions. The ketogenic diet has helped cancer patients, people with diabetes (type 1 and type 2), women with polycystic ovary syndrome, people with heart disease, and many others. So, where does the rumor that the ketogenic diet and ketosis may not be safe come from? Well, it starts with ketones. Rumors Spread Like Ketones in an Insulin Deficient Body One of the primary goals of the ketogenic diet is to enter ketosis (a normal metabolic process when ketones are produced for fuel). Ketosis is primarily regulated by the liver, which helps produce enough ketones to meet the body’s needs. However, ketone production can get out of hand when insulin is deficient, leading to ketoacidosis. This may be where the rumor that keto and ketosis are not safe came from. Ketoacidosis — A Serious Condition That Is Not Caused By The Ketogenic Diet Ketoacidosis is a serious condition caused by uncontrolled diabetes. It is brought on by being born without the ability to produce enough insulin (type 1 diabetes) or living a lifestyle that promotes insulin resistance (type 2 diabetes). In both cases, there isn’t enough insulin to tell that cells that energy is available (insulin deficiency). The lack of insulin signaling causes the fat cells and liver cells to go into starvation mode, even after a calorically dense meal. The fat cells begin to dump triglycerides into the blood to provide the other cells with energy because the cells are perceiving that there is no fuel available. Meanwhile, the liver starts mobilizing stored glycogen and using gluconeogenesis and ketogenesis to provide the body with sugar and ketones that it doesn’t need. All of this causes bloo Continue reading >>
The Physiology Of The Urinary System
Last newsletter, we examined the anatomy of the urinary system. Today, we're going to examine the urinary system's functions -- focusing almost entirely on how your kidneys (and more specifically, the kidneys' nephrons) actually filter and balance your blood. Understanding how this works, and how you can prevent and reverse damage to the process and even assist it, is fundamental to maintaining optimum health. We'll conclude by exploring what your doctor learns about you when examining the results of your urinalysis. Wouldn't it be nice to actually know what your doctor is talking about when she makes recommendations to you based on the results of your test? Quick review of the anatomy of the urinary system As we discussed previously, water, waste, and in fact virtually everything other than red and white blood cells are pulled out of the blood in the balled mass of arterioles known as the glomerulus, located at the front end of the nephron. All of this "waste" material then passes into the renal tubule portion of the nephron for "fine tuning." Keep in mind, that at this point, what we're referring to as waste contains virtually everything including the kitchen sink. If your body could not reclaim most of these elements, since many are essential for life, you would quickly die. That's why that as this pre-urine makes its way through the tubules of the nephron, it is fine tuned, with a bunch of things, including the water, that were previously extracted being put back into the bloodstream, as required by your body. In addition, some other things, such as medications, are pulled out in the tubules, as they are determined to be unnecessary during the process of fine tuning. To summarize: The primary purpose of kidney filtration is to balance out bio-chemicals in the bloods Continue reading >>
Ketone Supplements: More Harm Than Good?
Enjoy this article co-authored with my dear friend, Tatiana Schallert, who is co-serving with me, my ministry, and my family. I AM Love, Dr. Sharnael Have you noticed that Ketone supplements are so popular recently? I know my Facebook newsfeed is buzzing with different articles and brands promoting ketones. I honestly had no clue what the deal was so I decided to do some research, which is exactly what I encourage you to do before jumping on the bandwagon. There is a lot of information out there on this topic right now and from what I found – taking Exogenous Ketones may be more harmful than good. What are Ketones? Ketones are produced in the liver from fatty acids. Then they are consumed as alternative fuel by the body, particularly the brain, when blood sugar (glucose) is in short supply. The brain consumes lots of energy every day and it can’t run on fat directly – only in the form of glucose or ketones. Ketones are popularly known as “brain fuel.” Eating a no-carb, moderate-protein, and high-fat diet encourages the body to organically reach a state of Ketosis. It takes about 72 hours for the liver to be in full ketosis so the kidney can assimilate the changes as the ketones gradually increase. Then it takes about two weeks for your body to adjust to the new pathway. What Is Ketosis? When the body produces ketones it’s said to be in ketosis (you can test ketone levels through urine tests). The fastest way to get there is by fasting. However, fasting is not something we do forever. On the other hand, a low-carb or “keto” diet also leads to ketosis and is a more sustainable option. The idea of a ketogenic diet is to get the body to switch its fuel supply to run almost entirely on fat. As insulin levels become very low, fat burning increases dramatically Continue reading >>
