How Does Ketosis Occur

Ketosis

Ketosis

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 >>

Ketosis

Ketosis

Not to be confused with Ketoacidosis. Ketosis is a metabolic state in which some of the body's energy supply comes from ketone bodies in the blood, in contrast to a state of glycolysis in which blood glucose provides energy. Ketosis is a result of metabolizing fat to provide energy. Ketosis is a nutritional process characterised by serum concentrations of ketone bodies over 0.5 mM, with low and stable levels of insulin and blood glucose.[1][2] It is almost always generalized with hyperketonemia, that is, an elevated level of ketone bodies in the blood throughout the body. Ketone bodies are formed by ketogenesis when liver glycogen stores are depleted (or from metabolising medium-chain triglycerides[3]). The main ketone bodies used for energy are acetoacetate and β-hydroxybutyrate,[4] and the levels of ketone bodies are regulated mainly by insulin and glucagon.[5] Most cells in the body can use both glucose and ketone bodies for fuel, and during ketosis, free fatty acids and glucose synthesis (gluconeogenesis) fuel the remainder. Longer-term ketosis may result from fasting or staying on a low-carbohydrate diet (ketogenic diet), and deliberately induced ketosis serves as a medical intervention for various conditions, such as intractable epilepsy, and the various types of diabetes.[6] In glycolysis, higher levels of insulin promote storage of body fat and block release of fat from adipose tissues, while in ketosis, fat reserves are readily released and consumed.[5][7] For this reason, ketosis is sometimes referred to as the body's "fat burning" mode.[8] Ketosis and ketoacidosis are similar, but ketoacidosis is an acute life-threatening state requiring prompt medical intervention while ketosis can be physiological. However, there are situations (such as treatment-resistant Continue reading >>

Ketosis

Ketosis

There is a lot of confusion about the term ketosis among medical professionals as well as laypeople. It is important to understand when and why nutritional ketosis occurs, and why it should not be confused with the metabolic disorder we call ketoacidosis. Ketosis is a metabolic state where the liver produces small organic molecules called ketone bodies. Most cells in the body can use ketone bodies as a source of energy. When there is a limited supply of external energy sources, such as during prolonged fasting or carbohydrate restriction, ketone bodies can provide energy for most organs. In this situation, ketosis can be regarded as a reasonable, adaptive physiologic response that is essential for life, enabling us to survive periods of famine. Nutritional ketosis should not be confused with ketoacidosis, a metabolic condition where the blood becomes acidic as a result of the accumulation of ketone bodies. Ketoacidosis can have serious consequences and may need urgent medical treatment. The most common forms are diabetic ketoacidosis and alcoholic ketoacidosis. What Is Ketosis? The human body can be regarded as a biologic machine. Machines need energy to operate. Some use gasoline, others use electricity, and some use other power resources. Glucose is the primary fuel for most cells and organs in the body. To obtain energy, cells must take up glucose from the blood. Once glucose enters the cells, a series of metabolic reactions break it down into carbon dioxide and water, releasing energy in the process. The body has an ability to store excess glucose in the form of glycogen. In this way, energy can be stored for later use. Glycogen consists of long chains of glucose molecules and is primarily found in the liver and skeletal muscle. Liver glycogen stores are used to mai Continue reading >>

How Does A Ketogenic Diet Change Your Life?

How Does A Ketogenic Diet Change Your Life?

The ketogenic diet has changed many people’s lives in different ways: from weight loss to reversing diabetes to improving multiple health factors. Eating a diet high in fat, moderate in protein, and very low in carbohydrates, such as the ketogenic diet (or commonly known as “keto”), puts your body into a state of ketosis, a natural metabolic state in which your body is no longer using glucose as its main source of fuel, and instead it begins using ketones to get its energy. Ketones are produced when your body is burning fat because no glucose is available. It is important not to confuse ketosis, a completely harmless and normal metabolic state, with ketoacidosis, a dangerous condition that occurs mostly in type 1 diabetics when they create high levels of both glucose and ketones at the same time. On the ketogenic plan, blood glucose usually drops, so this is not a danger for most people. However, if you are a type 1 diabetic, check with your doctor before switching to the ketogenic way of eating. So being in ketosis simply means that you have switched from being a sugar-burner to a fat-burner. Ketones are created when you are metabolizing fat, whether it is from the fat in the foods you eat or from the fat around your belly. The ketogenic diet also is an anti-inflammatory way of eating. Chronic inflammation has been shown to be a significant contributor to metabolic syndrome, which includes obesity, insulin resistance, high blood pressure, and high cholesterol levels. Keto avoids foods that can cause inflammation, notably grains, sugar, and starchy carbohydrates such as potatoes and rice. Reducing inflammation may also improve leptin function in the body. Leptin is a hormone that sends signals to the brain that you have enough energy stored and that you are satiat Continue reading >>

What Are The Dangers Of The Ketosis Diet?

What Are The Dangers Of The Ketosis Diet?

In the late 1990s and early 2000s, when the "Atkins" and low carb dieting thing was just coming on in a big way, there was a terrific number of idiotic claims made about the dangers of it -- many of them confusing (as the questioner points out) diabetic ketoacidosis, a serious condition, with voluntary nutritional ketosis, even though there is no relation whatever. But, leaving all that aside, some caution is in order. The diet seems to stress the adrenals. This has been noted anecdotally by many people who've followed the diet. It was also noted by Dr Wolfgang Lutz, one of the early pioneers of the diet, who personally practiced the diet for 40-odd years, as well as advocated the diet to thousands of his patients. He noted in his book on the subject ("Life Without Bread" was the title, though it was published later I believe under a different title) that some patients would suffer mild autoimmune reactions that required small doses of corticosteroids to control. This sounds like what would happen if the adrenals are failing to produce a normal amount of steroids. You can find a lot more of a mostly-anecdotal nature by searching for "ketogenic jaminet". Paul Jaminet is a popular health blogger who has written about what he perceives to be problems with the ketogenic diet, including the possibility of deficiency of mucus and other key glycoproteins. He has some scientific backing for what he is saying, but it is far from air-tight. Read and judge for yourself. You can also learn a lot from the comments below his posts. Jaminet and others have also written about the risk of kidney stones on the ketogenic diet, and this is a serious concern, albeit a rare occurence. As far as the kidney stress goes: this would I believe be easy to avert simply by taking some alkali during Continue reading >>

Ketosis Explained – For Weight Loss, Health Or Performance

Ketosis Explained – For Weight Loss, Health Or Performance

Get Started Ketosis is a natural state for the body, when it is almost completely fueled by fat. This is normal during fasting, or when on a strict low-carb diet. Ketosis has many potential benefits, but there are also side effects. In type 1 diabetes and certain other rare situations excessive ketosis can even become dangerous. On this page you can learn all about how to harness the benefits of ketosis, while avoiding any problems. It all starts with understanding what ketosis is.

Ketones are produced if you eat very few carbs (that are broken down into blood sugar) and only moderate amounts of protein (excess protein can be converted to blood sugar). Ketones are produced in the liver, from fat. They are then consumed as fuel in the body, including by the brain. This is important as the brain is a hungry organ that consumes lots of energy every day,2 and it can’t run on fat directly. It can only run on glucose… or ketones. Maximizing fat burning On a ketogenic diet your entire body switches its fuel supply to run almost entirely on fat. Insulin levels become very low and fat burning increases dramatically. It becomes easy to access your fat stores to burn them off. This is o Continue reading >>

Ketosis, Ketones, And How It All Works

Ketosis, Ketones, And How It All Works

Ketosis is a process that the body does on an everyday basis, regardless of the number of carbs you eat. Your body adapts to what is put in it, processing different types of nutrients into the fuels that it needs. Proteins, fats, and carbs can all be processed for use. Eating a low carb, high fat diet just ramps up this process, which is a normal and safe chemical reaction. When you eat carbohydrate based foods or excess amounts of protein, your body will break this down into sugar – known as glucose. Why? Glucose is needed in the creation of ATP (an energy molecule), which is a fuel that is needed for the daily activities and maintenance inside our bodies. If you’ve ever used our keto calculator to determine your caloric needs, you will see that your body uses up quite a lot of calories. It’s true, our bodies use up much of the nutrients we intake just to maintain itself on a daily basis. If you eat enough food, there will likely be an excess of glucose that your body doesn’t need. There are two main things that happen to excess glucose if your body doesn’t need it: Glycogenesis. Excess glucose will be converted to glycogen and stored in your liver and muscles. Estimates show that only about half of your daily energy can be stored as glycogen. Lipogenesis. If there’s already enough glycogen in your muscles and liver, any extra glucose will be converted into fats and stored. So, what happens to you once your body has no more glucose or glycogen? Ketosis happens. When your body has no access to food, like when you are sleeping or when you are on a ketogenic diet, the body will burn fat and create molecules called ketones. We can thank our body’s ability to switch metabolic pathways for that. These ketones are created when the body breaks down fats, creating Continue reading >>

Ketosis: What Is Ketosis?

Ketosis: What Is Ketosis?

Ketosis is a normal metabolic process. When the body does not have enough glucose for energy, it burns stored fats instead; this results in a build-up of acids called ketones within the body. Some people encourage ketosis by following a diet called the ketogenic or low-carb diet. The aim of the diet is to try and burn unwanted fat by forcing the body to rely on fat for energy, rather than carbohydrates. Ketosis is also commonly observed in patients with diabetes, as the process can occur if the body does not have enough insulin or is not using insulin correctly. Problems associated with extreme levels of ketosis are more likely to develop in patients with type 1 diabetes compared with type 2 diabetes patients. Ketosis occurs when the body does not have sufficient access to its primary fuel source, glucose. Ketosis describes a condition where fat stores are broken down to produce energy, which also produces ketones, a type of acid. As ketone levels rise, the acidity of the blood also increases, leading to ketoacidosis, a serious condition that can prove fatal. People with type 1 diabetes are more likely to develop ketoacidosis, for which emergency medical treatment is required to avoid or treat diabetic coma. Some people follow a ketogenic (low-carb) diet to try to lose weight by forcing the body to burn fat stores. What is ketosis? In normal circumstances, the body's cells use glucose as their primary form of energy. Glucose is typically derived from dietary carbohydrates, including: sugar - such as fruits and milk or yogurt starchy foods - such as bread and pasta The body breaks these down into simple sugars. Glucose can either be used to fuel the body or be stored in the liver and muscles as glycogen. If there is not enough glucose available to meet energy demands, th Continue reading >>

The Beginners Guide To Ketosis: Investigating Low-carb, High-fat Eating

The Beginners Guide To Ketosis: Investigating Low-carb, High-fat Eating

The only hard and fast rule of health is that health is personal and what works well for one person may not work for someone else. Aside from that rule, there are “frameworks” that seem to benefit large groups of people. One more level down from that are alternative strategies that benefit smaller groups. Ketosis is likely one of those alternative strategies that works well for certain, smaller groups of people. So, right off the bat I want you to understand that Ketosis might not be for everyone. I’m going to lay out the case for potential benefits of Ketosis. If it sounds interesting and beneficial to you, then consider trying it. (see our free cheat sheet to help you). What is Ketosis Ketosis occurs when liver glycogen gets depleted and the body burns fatty acids for fuel. The primary driver of this state is a very low carbohydrate intake. Often, it also requires a low protein, higher fat intake. You can also achieve a state of ketosis by not eating altogether. The creation of ketones is a byproduct of this metabolic state. Ketones are a source of fuel, just as glucose is a source of fuel. Ketones tend to have some added benefits, though. What role does Ketosis play in human health? Ketosis allows our bodies to function in the absence of carbohydrates, both physically and mentally. Instead of burning carbohydrates, or converting protein to glucose, the body burns ketones. This is pretty much a survival mechanism. It allows your body to function in a state of caloric deprivation. This is why ketosis often gets bad press (as it’s linked to “starvation”). Being a survival mechanism doesn’t make it invalid as a strategy, though. There can still be potential benefits to be had. Let’s cover a few of them… Ketosis and Accelerated Fat Loss Being in ketosis Continue reading >>

7 Signs You Might Be In Ketosis When Doing The Ketogenic Diet

7 Signs You Might Be In Ketosis When Doing The Ketogenic Diet

One of the main goals of starting the ketogenic diet is to get your body into a metabolic state known as ketosis. Note: If you don’t know what the ketogenic is all about then check out the Ketogenic Diet: Beginner’s Guide to Keto and Weight Loss. This is when your body starts to produce a lot of ketones to supply energy for your body. Why is this good? Because it means your body has converted from a sugar-burner to a fat-burner. If your body is burning fat for energy then something amazing starts to happen. The fat on your body starts to disappear. But how do you know when you’re in ketosis? Besides using test strips or an instrument there are some signs that your body will give. 7 Signs You Might Be in Ketosis These don’t 100% guarantee that your body is in ketosis but if it is in ketosis then these signs will appear. 1. Weight Loss One of the obvious signs of ketosis is weight loss but this can also be pretty deceptive because many people don’t experience the kind of weight loss that they expect. This can happen for a variety of reasons but when you get close to entering ketosis or do enter ketosis you’ll find that you lose a healthy amount of weight quickly. For example, when you switch to low carbs you usually experience significant weight loss in the first week. In fact, my wife lost 12 lbs in the first 28 days of Keto and I lost 13. This isn’t your body burning fat but finally being able to release the water that was being held by the fat cells. If your fat cells don’t release this water then they can’t flow through the bloodstream to be used as fuel so losing water weight is a good thing. After the initial rapid drop in water weight, you should continue to lose body fat consistently if you are able to stick with the low-carb aspects of the diet Continue reading >>

Lose Weight By Achieving Optimal Ketosis

Lose Weight By Achieving Optimal Ketosis

Do you want to lose weight? Here’s number 16 of my 18 best tips. All of the published tips can be found on the How to Lose Weight page. Before we get started, here’s a short recap of the tips so far: The first and most crucial piece of advice was to choose a low-carb diet. The next were eating when hungry, eating real food, eating only when hungry, measuring progress wisely, being persistent, avoiding fruit, beer and artificial sweeteners, review your medications, stressing less and sleeping more, eating less dairy and nut products, stocking up on vitamins and minerals, using intermittent fasting and finally, exercising smart. This is number sixteen: 16. Get into optimal ketosis Warning: Not recommended for type 1 diabetics, see below. We’ve now arrived at tip number 16. If you’re still having trouble losing weight, despite following the 15 pieces of advice listed above, it might be a good idea to bring out the heavy artillery: optimal ketosis. Many people stalling at weight plateaus while on a low carb diet have found optimal ketosis helpful. It’s what can melt the fat off once again. So how does this work? A quick run-through: The first tip was to eat low carb. This is because a low-carb diet lowers your levels of the fat-storing hormone insulin, allowing your fat deposits to shrink and release their stored energy. This tends to cause you to want to consume less calories than you expend – without hunger – and lose weight. Several of the tips mentioned above are about fine-tuning your diet to better this effect.

If not the easiest way is watching this high quality 11-minute video course on how to eat LCHF, and the most important things to think a Continue reading >>

10 Signs And Symptoms That You're In Ketosis

10 Signs And Symptoms That You're In Ketosis

The ketogenic diet is a popular, effective way to lose weight and improve health. When followed correctly, this low-carb, high-fat diet will raise blood ketone levels. These provide a new fuel source for your cells, and cause most of the unique health benefits of this diet (1, 2, 3). On a ketogenic diet, your body undergoes many biological adaptions, including a reduction in insulin and increased fat breakdown. When this happens, your liver starts producing large amounts of ketones to supply energy for your brain. However, it can often be hard to know whether you're "in ketosis" or not. Here are 10 common signs and symptoms of ketosis, both positive and negative. People often report bad breath once they reach full ketosis. It's actually a common side effect. Many people on ketogenic diets and similar diets, such as the Atkins diet, report that their breath takes on a fruity smell. This is caused by elevated ketone levels. The specific culprit is acetone, a ketone that exits the body in your urine and breath (4). While this breath may be less than ideal for your social life, it can be a positive sign for your diet. Many ketogenic dieters brush their teeth several times per day, or use sugar-free gum to solve the issue. If you're using gum or other alternatives like sugar-free drinks, check the label for carbs. These may raise your blood sugar levels and reduce ketone levels. The bad breath usually goes away after some time on the diet. It is not a permanent thing. The ketone acetone is partly expelled via your breath, which can cause bad or fruity-smelling breath on a ketogenic diet. Ketogenic diets, along with normal low-carb diets, are highly effective for losing weight (5, 6). As dozens of weight loss studies have shown, you will likely experience both short- and long Continue reading >>

When My Boyfriend Drinks Alcohol He Smells Like Oranges. Is There A Reason For This?

Thanks for the A2A. He may be experiencing ketosis. Ketosis occurs when your body does not have sufficient glucose to use as fuel, and starts to use alternatives such as proteins and fats instead. It's not necessarily harmful (low carb diets will induce ketosis) but it can be associated with conditions such as diabetes and over-active thyroid. He should discuss this with a doctor.

What Would The Effect Of A 30-day Water Fast Be? My Friend Wants To Do A 30-day Water Fast To Detox, But I Am Kind Of Concerned About It. She Has Never Done A Water Fast Before, So 30 Days Seems A Bit Overkill.

What Would The Effect Of A 30-day Water Fast Be? My Friend Wants To Do A 30-day Water Fast To Detox, But I Am Kind Of Concerned About It. She Has Never Done A Water Fast Before, So 30 Days Seems A Bit Overkill.

First off, Don’t worry too much that your friend will actually make it 30 days. If she has never fasted before, it is extremely unlikely she makes it that long. I have been fasting pretty hardcore on and off for 5 years and my personal best is 13 days. Here’s a video of my early days if you think I’m full of BS. That being said, here is what happens in the body when you fast. The body burns any food that was eaten recently, turning it into an easily burned form of energy called glycogen. Next, the body turns to stored glycogen stored in the liver. Most people seem to have 2–3 days worth of “easy-access” glycogen in the blood stream and liver. Over the first, give or take, 3 days of the fast you deplete the glycogen stores and then your body turns to an alternate source: fat stores. This is an alternate metabolic pathway that all humans (if not hindered in some rare genetically related manner) have the capability of. Often referred to as “being in ketosis” your body produces chemicals that break down fat to ketone bodies (often just called ketones). The body is also able to produce a small amount of glycogen, through a process called gluconeogenesis. When you combine the ketones and the tiny amount of glucose created from your fat stores, you body runs incredibly efficiently for a very long time. The amount of time is directly tied to how much fat your body has stored. So, that is what is happening in the body. But what will your friend experience: Massive weight loss. Let me reiterate, you are burning only your fat stores for energy, so that beer belly is going away. Loss of water weight. A lot of water is stored in fat. When this breaks down it is easy to get dehydrated. Tell your friend to drink water like it is her day job. If she is going 30 days (ag Continue reading >>
