What Is Starvation Ketosis?

How To Survive 40 Days Starvation

The obesity epidemic and how to beat it This special mini-series tells you the latest on how metabolic interventions can make genes work to slim you down. This series was first published in Science and Society 21 Some conventional health fears need to be questioned, as, like fasting, they may contain health-restoring opportunities. Dr. Mae-Wan Ho explains Fear of ketosis Ketosis is the dreaded condition of having too much of certain metabolic products called ketones circulating in the blood. Generations of physicians have been taught to be very afraid of it, because of the potentially fatal episodes of ‘ketoacidosis’ in people with diabetes. In these individuals, severe insulin deficiency causes fatty acids to pour out of fat tissues and undergo metabolic conversion in the liver to the ketones, D-b-hydroxybutyrate and acetoacetate. The concentration of ketones circulating in the blood can reach 25mM, upsetting the delicate acid-base balance in the blood, so it turns severely acid. The body excretes ketones in the urine, losing a lot of sodium and potassium ions in the process. At the same time, the high blood glucose is also passed out of the body in the urine together with a lot of water, leading to a drop in blood volume. All these processes contribute to death, if untreated. However, the fear of ketosis may be exaggerated, as milder forms of it occur under other circumstances, and may have therapeutic potential. Such is the claim of senior biochemist Richard Veech in the Unit of Metabolic Control, in one of the National Institutes of Health in the United States. He has a number of prominent veteran biochemists supporting his ideas, and, together, they have written a fascinating review on the potential therapeutic uses of ketosis.

Ketosis In An Evolutionary Context

Humans are unique in their remarkable ability to enter ketosis. They’re also situated near the top of the food chain. Coincidence? During starvation, humans rapidly enter ketosis; they do this better than king penguins, and bears don’t do it at all. Starvation ketosis Humans maintain a high level of functionality during starvation. We can still hunt & plan; some would even argue it’s a more finely tuned state, cognitively. And that’s important, because if we became progressively weaker and slower, chances of acquiring food would rapidly decline. Perhaps this is why fasting bears just sleep most of the time: no ketones = no bueno..? Animals with a low brain/carcass weight ratio (ie, small brain) don’t need it. Babies and children have a higher brain/carcass weight ratio, so they develop ketosis more rapidly than adults. Is this a harmful process? No, more likely an evolutionary adaptation which supports the brain. The brain of newborn babies consumes a huge amount of total daily energy, and nearly half comes from ketones. A week or so later, even after the carbohydrate content of breast milk increases, they still don’t get “kicked out of ketosis” (Bourneres et al., 1986). If this were a harmful state, why would Nature have done this? …and all those anecdotes, like babies learn at incredibly rapid rates… coincidence? Maybe they’re myths. Maybe not. Ketosis in the animal kingdom Imagine a hibernating bear: huge adipose tissue but small brain fuel requirement relative to body size and total energy expenditure. No ketosis, because brain accounts for less than 5% of total metabolism. In adult humans, this is around 19-23%, and babies are much higher (eg, Cahill and Veech, 2003 & Hayes et al., 2012).

Ketoacidosis: A Complication Of Diabetes

Diabetic ketoacidosis is a serious condition that can occur as a complication of diabetes. People with diabetic ketoacidosis (DKA) have high blood sugar levels and a build-up of chemicals called ketones in the body that makes the blood more acidic than usual. Diabetic ketoacidosis can develop when there isn’t enough insulin in the body for it to use sugars for energy, so it starts to use fat as a fuel instead. When fat is broken down to make energy, ketones are made in the body as a by-product. Ketones are harmful to the body, and diabetic ketoacidosis can be life-threatening. Fortunately, treatment is available and is usually successful. Symptoms Ketoacidosis usually develops gradually over hours or days. Symptoms of diabetic ketoacidosis may include: excessive thirst; increased urination; tiredness or weakness; a flushed appearance, with hot dry skin; nausea and vomiting; dehydration; restlessness, discomfort and agitation; fruity or acetone smelling breath (like nail polish remover); abdominal pain; deep or rapid breathing; low blood pressure (hypotension) due to dehydration; and confusion and coma. See your doctor as soon as possible or seek emergency treatment if you develop symptoms of ketoacidosis. Who is at risk of diabetic ketoacidosis? Diabetic ketoacidosis usually occurs in people with type 1 diabetes. It rarely affects people with type 2 diabetes. DKA may be the first indication that a person has type 1 diabetes. It can also affect people with known diabetes who are not getting enough insulin to meet their needs, either due to insufficient insulin or increased needs. Ketoacidosis most often happens when people with diabetes: do not get enough insulin due to missed or incorrect doses of insulin or problems with their insulin pump; have an infection or illne Continue reading >>

The New Nutritional Starvation Diet

Is the horse I’m beating dead, yet? Well, get it while it’s hot, I guess. Dogpile! So yesterday’s installment was about how difficult it is to source a lot of fat from animals in the wild, most places. Duck added a supplemental comment as well. And, what with Chris Kresser (Is a Low-Carb Diet Ruining Your Health?) and Tom Naughton (Reactions To Arguments About Ketosis) displaying increasing skepticism over the healthfulness of very low carbohydrate and/or ketogenic diets in perpetuity, let’s just keep putting fuel on the fire, shall we? I’ve been lightly participating in both comment threads linked above; rather politely, too. There was a comment by “Damocles” this morning I found interesting and to me, offered a clue as to why so many defend ketosis in spite of what it does to glucose tolerance (See Inuit and Stefansson). From an evolutionary perspective, it makes perfect sense for the body to increase insulin resistance during ketosis. Its a signal for the body that carbs are very scarce at the moment. So by increasing insulin resistance, cells wich can well burn lipits and ketons refuse to snatch the glucose from the blood, – leaving more for the most important organ: the brain. As the brain needs (even in ketosis) a certain amount of glucose to funtion. The insulin resistance in ketosis is a smart allocation of glucose (to the brain), when carbs are coming available, and to not have to rely on gluconeogenesis from proteins. When carbs come available again regularily, the insulin resistance can be reduced, so all the other cells can uptake this fuel. Physiologically, he’s correct. But here’s the problem. Damocles: “From an evolutionary perspective, it makes perfect sense for the body to increase insulin resistance during ketosis.” Yes, this is Continue reading >>

Alcoholic Ketoacidosis

Background In 1940, Dillon and colleagues first described alcoholic ketoacidosis (AKA) as a distinct syndrome. AKA is characterized by metabolic acidosis with an elevated anion gap, elevated serum ketone levels, and a normal or low glucose concentration. [1, 2] Although AKA most commonly occurs in adults with alcoholism, it has been reported in less-experienced drinkers of all ages. Patients typically have a recent history of binge drinking, little or no food intake, and persistent vomiting. [3, 4, 5] A concomitant metabolic alkalosis is common, secondary to vomiting and volume depletion (see Workup). [6] Treatment of AKA is directed toward reversing the 3 major pathophysiologic causes of the syndrome, which are: This goal can usually be achieved through the administration of dextrose and saline solutions (see Treatment).

The Truth About Ketosis & Low-carb Diets, Backed By Science

A lot of people are confused by the term “ketosis.” You may read that it is a “dangerous state” for the body, and it does sound abnormal to be “in ketosis.” But ketosis merely means that our bodies are using fat for energy. Ketones (also called ketone bodies) are molecules generated during fat metabolism, whether from the fat in the almonds you just ate or fat you were carrying around your middle. When our bodies are breaking down fat for energy, most of it gets converted to energy, but ketones are also produced as part of the process. When people eat less carbohydrates, their bodies turn to fat for energy, so it makes sense that more ketones are generated. Some of those ketones (acetoacetate and ß-hydroxybutyrate) are used for energy; the heart muscle and kidneys, for example, prefer ketones to glucose. Most cells, including the brain cells, are able to use ketones for at least part of their energy. Is ketosis a bad thing? There is an assumption that if a body is burning a lot of fat for energy, it must not be getting “enough” glucose. However, there is no indication, from studying people on reduced carbohydrate diets, that this is the case (though there is usually a short period of adjustment, less than a week, in most cases). It takes about 72 hours to burn up all of the reserve glycogen (sugar loads). Although it’s true that our bodies can’t break fat down directly into glucose (though, interestingly, they easily use glucose to make fat), our bodies can convert some of the protein we eat into glucose. Indeed, this works well for people who don’t tolerate a lot of sugar, because this conversion happens slowly so it doesn’t spike blood glucose. What is the danger of ketosis? It is important that if you are following a ketogenic nutritional pro Continue reading >>

Starvation Ketoacidosis: A Cause Of Severe Anion Gap Metabolic Acidosis In Pregnancy

Abstract Pregnancy is a diabetogenic state characterized by relative insulin resistance, enhanced lipolysis, elevated free fatty acids and increased ketogenesis. In this setting, short period of starvation can precipitate ketoacidosis. This sequence of events is recognized as "accelerated starvation." Metabolic acidosis during pregnancy may have adverse impact on fetal neural development including impaired intelligence and fetal demise. Short periods of starvation during pregnancy may present as severe anion gap metabolic acidosis (AGMA). We present a 41-year-old female in her 32nd week of pregnancy, admitted with severe AGMA with pH 7.16, anion gap 31, and bicarbonate of 5 mg/dL with normal lactate levels. She was intubated and accepted to medical intensive care unit. Urine and serum acetone were positive. Evaluation for all causes of AGMA was negative. The diagnosis of starvation ketoacidosis was established in absence of other causes of AGMA. Intravenous fluids, dextrose, thiamine, and folic acid were administered with resolution of acidosis, early extubation, and subsequent normal delivery of a healthy baby at full term. Rapid reversal of acidosis and favorable outcome are achieved with early administration of dextrose containing fluids.

Starvation Acidosis

acidosis [as″ĭ-do´sis] 1. the accumulation of acid and hydrogen ions or depletion of the alkaline reserve (bicarbonate content) in the blood and body tissues, resulting in a decrease in pH. 2. a pathologic condition resulting from this process, characterized by increase in hydrogen ion concentration (decrease in pH). The optimal acid-base balance is maintained by chemical buffers, biologic activities of the cells, and effective functioning of the lungs and kidneys. The opposite of acidosis is alkalosis. adj., adj acidot´ic. Acidosis usually occurs secondary to some underlying disease process; the two major types, distinguished according to cause, are metabolic acidosis and respiratory acidosis (see accompanying table). In mild cases the symptoms may be overlooked; in severe cases symptoms are more obvious and may include muscle twitching, involuntary movement, cardiac arrhythmias, disorientation, and coma. In general, treatment consists of intravenous or oral administration of sodium bicarbonate or sodium lactate solutions and correction of the underlying cause of the imbalance. Many cases of severe acidosis can be prevented by careful monitoring of patients whose primary illness predisposes them to respiratory problems or metabolic derangements that can cause increased levels of acidity or decreased bicarbonate levels. Such care includes effective teaching of self-care to the diabetic so that the disease remains under control. Patients receiving intravenous therapy, especially those having a fluid deficit, and those with biliary or intestinal intubation should be watched closely for early signs of acidosis. Others predisposed to acidosis are patients with shock, hyperthyroidism, advanced circulatory failure, renal failure, respiratory disorders, or liver disease. Continue reading >>

Reversing Type 2 Diabetes with Nutritional Ketosis

Is Ketosis Dangerous?

You may have heard from your doctor that ketosis is a life-threatening condition. If so, your doctor is confusing diabetic ketoacidosis (DKA) with nutritional ketosis, or keto-adaptation. First, some semantics. Our body can produce, from fat and some amino acids, three ketone bodies (a “ketone” refers to the chemical structure where oxygen is double-bonded to carbon sandwiched between at least 2 other carbons). These ketone bodies we produce are: acetone, acetoacetone, and beta-hydroxybutyrate (B-OHB). [For anyone who is interested, they are the 3 most right structures on the figure, below.] Why do we make ketones? For starters, it’s a vital evolutionary advantage. Our brain can only function with glucose and ketones. Since we can’t store more than about 24 hours’ worth of glucose, we would all die of hypoglycemia if ever forced to fast for more than a day. Fortunately, our liver can take fat and select amino acids (the building blocks of proteins) and turn them into ketones, first and foremost to feed our brains. Hence, our body’s ability to produce ketones is required for basic survival. What is diabetic ketoacidosis? When diabetics (usually Type I diabetics, but sometimes this occurs in very late-stage, insulin-dependent, Type II diabetics) fail to receive enough insulin, they go into an effective state of starvation. While they may have all the glucose in the world in their bloodstream, without insulin, they can’t get any into their cells. Hence, they are effectively going into starvation. The body does what it would do in anyone – it starts to make ketones out of fat and proteins. Here’s the problem: the diabetic patient in this case can’t produce any insulin, so there is no feedback loop and they continue to produce more and more ketones withou Continue reading >>

How Do I Break The Starvation Mode And Maintain Ketosis?

How do I break the starvation mode and maintain ketosis? How do I break the starvation mode and maintain ketosis? I am a frequent reader of BB.com and have been in the background more or less since the end of 2005. Without a lot of background I am fairly certain my body has dropped my metabolism in response to years of low calorie PSMF'ing with calorie intake on average <1200 a day. After resolving some personal issues I seem to dropping some weight although fairly slow and not even close to my past experience of 2.5 lbs per week over 8 months. I understand after research here that I need to up the calories, weight train and bulk and cut separately. I was 268 around Oct 05 and 249 now and 66". Most of the progress has been in the last two months. But back to my question, if I increase the protein and fat calories will that break the cycle while maintaining ketosis? Will weight training break the cycle, maintain muscle mass and stay in ketosis? Will bike rides three days a week break the cycle? What I am asking is will the body shut down with a low calorie intake regardless of the work performed? I have to stay off carbs, they seemed to be utilized at a rate of 1 lb gained for every 1 lb consumed. I am eating some green veggies, salad, cauliflower and broc**** so I am not competely carb free. This is very frustrating because keto dieting has really never failed to show results until the last 12-18 months. - 2 scrambled eggs and 2 slices of bacon (breakfast) - Cappuccino, dry but with some milk and Spenda - 7 ounces of canned salmon with 1 oz mayo (lunch) - 2 breasts and a thigh from KFC with the skin and batter removed (dinner) I guess it is possible that I am not in starvation mode but just taking in to many calories with to little activity resulting in slow weightloss Continue reading >>

Starvation Ketoacidosis In Pregnancy

Abstract Starvation ketosis outside pregnancy is rare and infrequently causes a severe acidosis. Placental production of hormones, including glucagon and human placental lactogen, leads to the insulin resistance that is seen in pregnancy, which in turn increases susceptibility to ketosis particularly in the third trimester. Starvation ketoacidosis in pregnancy has been reported and is usually precipitated by a period of severe vomiting. Ketoacidosis is likely to have important implications for fetal survival as ketoacidosis in women with type 1 diabetes mellitus is associated with intrauterine death. This article features four cases of women with vomiting in the third trimester of pregnancy associated with a severe metabolic acidosis. The mechanism underlying ketogenesis, the evidence for accelerated ketogenesis in pregnancy and other similar published cases are reviewed. A proposed strategy for management of these women is presented. Continue reading >>

Case Of Nondiabetic Ketoacidosis In Third Term Twin Pregnancy | The Journal Of Clinical Endocrinology & Metabolism | Oxford Academic

We provided appropriate management with fluid infusion after cesarean delivery. The patient and her two daughters survived, and no disabilities were foreseen. Alcohol, methanol, and lactic acid levels were normal. No signs of renal disease or diabetes were present. Pathological examination revealed no abnormalities of the placentae. Toxicological tests revealed a salicylate level of less than 5 mg/liter, an acetaminophen level of less than 1 mg/liter, and an acetone level of 300 mg/liter (reference, 520 mg/liter). We present a case of third term twin pregnancy with high anion gap metabolic acidosis due to (mild) starvation. Starvation, obesity, third term twin pregnancy, and perhaps a gastroenteritis were the ultimate provoking factors. In the light of the erroneous suspicion of sepsis and initial fluid therapy lacking glucose, one wonders whether, under a different fluid regime, cesarean section could have been avoided. Severe ketoacidosis in the pregnant woman is associated with impaired neurodevelopment. It therefore demands early recognition and immediate intervention. A 26-yr-old patient was admitted to our hospital complaining of rapid progressive dyspnea and abdominal discomfort. She was pregnant with dichorial, diamniotic twins for 35 wk and 4 d. Medical history showed that she was heterozygous for hemochromatosis. Two years before, she had given birth to a healthy girl of 3925 g by cesarean section, and 1 yr before, she had had a spontaneous abortion. Her preadmission outpatient surveillance revealed slightly elevated blood pressure varying from 132158 mm Hg systolic and 7995 mm Hg diastolic. Glucose and glycosylated hemoglobin were tested at 24 wk and were normal at 4.6 mmol/liter and 5.4% (36 mmol/mol), respectively. Urine analysis at the outpatient obstetri Continue reading >>

Renal Fellow Network: Starvation Ketosis: A Rare Cause Of Metabolic Acidosis

Starvation Ketosis: A Rare Cause of Metabolic Acidosis Asa child growing up in India, I have seen several family members performingritual fasting. Fasting is aubiquitous religio-cultural practice that is found, in varying forms, acrossthe world. The month-long Ramadan and Buddhist Lent fasts are examples ofreligious observances practiced by followers of Islam, and Buddhism,respectively. These fasts are characterized by a documented impact on metabolic health , which can be minimized by well-known management strategies .The practice of fastingis a major part of Hinduism and can range from light restriction toextreme abstention. Mahatma Gandhi was a fervent supporter of fasting byreligious convictionand as a way of freeingoneself of theconstraints of the body. He used fasting as a means of exerting politicalpressure and engaged in several hungerstrikesto protest withnon-violence. Inthe western countries, starvation ketosis or ketoacidosis has been reported inindividuals with strict dieting (e.g. carb-restricted, ketogenic diets or Atkins diet), extreme exercise, andrarely with malnutrition. Few cases of starvation-induced ketoacidosis during pregnancy and lactation , and during the perioperative period have also been reported in literature. Isaw a young non-verbal woman with quadriplegia who was admitted from a nursinghome with a two-day history of worsening abdominal pain and leakage around herpercutaneous endoscopic gastrostomy(PEG) tube site. Her medical history was significant for severe developmentaldelay and chronic constipation. She was afebrile and the rest of the vitalswere stable. Her PEG tube feeds had been stopped one day prior to the hospitaladmission due to abdominal pain. Additionally, she received small doses of ivmorphine for pain control. Due to no oral Continue reading >>

Ketosis Vs. Ketoacidosis (dka): What Is The Difference?

Let’s break it down so that you can understand exactly what ketosis is and how it differs from ketoacidosis. But the states they refer to are nothing alike. In this case, maybe mistakes are understandable. Many people who believe that ketosis is dangerous are mixing it up with another state called "ketoacidosis." The two words do sound very similar. And some people simply make mistakes. Profit motives tend to muddy up the works when it comes to getting clear, factual information about your health. Well, there are a lot of individuals and companies which all have their own goals and motivations. Where do these misperceptions come from? Here’s the thing though … that is all misinformation. You then Googled something like, "low carb dangerous" and found a list of link-bait articles informing you that low-carb is a ketogenic diet, and ketosis is a dangerous metabolic state which can be fatal. And then maybe someone said something to you like, "What are you thinking? Low-carb is a dangerous diet." If you are thinking about starting a low-carb diet, maybe you have mentioned it to some of your family or friends. By the time you finish reading this article, you will understand why low-carb is a safe diet. Continue reading >>
