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. 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). The main ketone bodies used for energy are acetoacetate and β-hydroxybutyrate, and the levels of ketone bodies are regulated mainly by insulin and glucagon. 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. 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. For this reason, ketosis is sometimes referred to as the body's "fat burning" mode. 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 >>
Ketone Strips: Are They Legit?
These days, everyone is a keto dieter, but very few actually know they’re in ketosis. Sure, you can follow the diet and take the supplements, but if it’s all predicated on reaching a certain metabolic condition, wouldn’t you want to know if you’ve achieved it? Ketone strips fall into two distinct categories that dictate the accuracy of the test you are taking. These two categories are urine and blood. The degree to which ketone strips help you to successfully monitor your blood ketone levels will be greatly affected by which of these you use. Think of a urinalysis as the book jacket version, and a blood test as the entire Moby Dick novel in regard to detail. Depending where you are on the commitment scale, you’ll want to make sure you’re using the right test for your needs. Below, we’ve listed the various types, brands, and benefits/detriments of each of the ketone strips. Check them out, and see which one suits your needs best, and most importantly, helps you remain in ketosis. Ketone Strips: Urine Analysis Using urinalysis to test for ketones is simply getting a “30,000 foot view” of the ketones in your system. The body regularly emits anywhere from 3 to 15 milligrams of ketones a day. Increased amounts of ketones in the urine (acetoacetate) can show you that there is in fact an excess of ketones your system, however ketone strips that evaluate the urine will not report the amount of ketones in the blood – ketonaemia – which is where the real work is done. The benefit of using the urinalysis ketone strips at the beginning of your ketogenic diet, is that you’ll save money of the bat in case you choose not to pursue the diet later on. And, as your body initially gets into ketosis, you’ll find value in the measurements. But once your body adapts Continue reading >>
Source Many low-carbohydrate dieters utilize ketosis strips as a way to determine whether their body is reacting to the low-carb or low glycemic diet appropriately. The small strips test urine and measure whether or not you have achieved ketosis. Ketosis and Low-Carbohydrate Diets The father of the low-carbohydrate diet, Dr. Robert Atkins, brought the concept of ketosis to the popular consciousness when he penned his first book, Dr. Atkins Diet Revolution, in 1972. At the time, Dr. Atkins suggested that in the process of a low-carbohydrate diet, the body achieves a process known as ketosis. When you are in ketosis, your body is burning stored fat as its primary source of fuel, causing ketones to enter your urine. Ketosis strips allow you to measure whether you are in ketosis. If you aren't in ketosis when low-carbohydrate or semi-low-carbohydrate dieting, then you may need to reduce carbohydrates further or look for hidden sugars in the foods you're eating. Signs of Ketosis Aside from using ketosis strips to test for ketosis, you may also notice other signs indicating you have entered this metabolic state, including: Bad breath Metallic taste in your mouth Increased energy, or even jitteriness Increased thirst and urine output Is Ketosis Dangerous? Many people fear ketosis is a dangerous physical state. It isn't. It merely means your body is utilizing its own fat as its primary source of fuel. The result is weight loss. Ketosis Strips Ketosis strips, also known as Ketostix, are small plastic strips that have a chemically-reactive indicator pad on the tip. You use the strips to test your urine to determine whether you are in ketosis. How to Use Using ketosis strips is relatively easy. You can either hold it in the flow of urine and take a reading after about 15 seconds, Continue reading >>
A Quick Primer On The Ketone Test Strips...
A Quick primer on the Ketone Test Strips... Questions about ketones, ketosis, KetoStix, and its implications and misconceptions have always been one of the most common querries at Low Carb Luxury. We'll try and clear up some of those mysteries here. So... what are they? You'll hear them referred to as KetoStix (the original brand name), Urine Test Strips, Reagent Strips, Ketone Testing Strips, and Lipolysis Test Strips. Depending on the plan you follow and whether you are new to this way of life, or an old timer from the 70's, you'll be referring to them as one name or another if your plan calls for being in Ketosis. Please note, we're not here to debate the merits of Ketogenic vs non-Ketogenic diets here, so don't send me mail of disagreement. For me personally, being in Ketosis is my ideal state and keeps my body's systems at their best. The Ketosis we're talking about here is what Dr. Atkins refers to as "Benign Dietary Ketosis" (or BDK), and should never be confused with Acidosis — a dangerous state for diabetics and those in advanced starvation where acetone builds in the blood and tissues. People will sometimes tell you that producing ketones is dangerous for the body. This is simply misinformation. They're confusing ketosis (the state from a Ketogenic diet) with ketoacidosis (or acidosis) which occurs in uncontrolled diabetes and/or starvation. Ketones? Ketones are incompletely burned carbon fragments. The very fact that they are less efficient as fuel is what makes them give you that 'metabolic advantage.' Some of the calories burned are not used to their full capacity... hence the person can eat more calories when in ketosis than when not, and still lose the same amount of weight. Ketoacids are short (four carbons long.) It's important because in that way the Continue reading >>
What Are Ketone Test Strips?
When your blood sugar runs high for an extended period of time, your body turns to fat reserves in order to get the energy it needs. The byproduct of this process is ketones, which show up in your blood and urine. Ketones can indicate hyperglycemia, which can be a serious situation if not treated properly. Ketone test strips can help determine the level of ketones in either urine or blood. Testing ketones with a blood-based test strip that you insert in a meter is just like testing your blood sugar. Testing with a urine strip means you either collect a small sample of urine or urinate directly onto the strip. Though testing with blood might be more accurate, it is also much more expensive. That's why so many of those with diabetes chose to go with urine ketone test strips. Understanding ketone test strip results Urine ketone test strips are looking for acetoacetic acid in the urine. This acid reacts with nitroprusside, a chemical in the strip, to produce a color. This color corresponds with a chart that comes packaged along with your test strips, usually on the outside of the vial. Typically, the results include negative, trace, moderate or large ketones. Negative ketones are a good sign. Trace ketones mean you should treat your high blood sugar as you normally would. Moderate or large ketones mean that your blood sugar has been too high for a while. Take the test a second time to confirm, then give your doctor a call. Options for ketone test strips When choosing urine ketone test strips, keep in mind how often you will use them. Test strips in a vial must be used before the expiration date, which is typically within six months after opening the package. Test strips that are individually packaged in foil cost a bit more, but will last much longer than those in a vial. I Continue reading >>
How Do Ketone Testing Strips Work?
Ketones and ketosis are no mysteries thanks to ketone testing strips. They are called KetoStix (the first brand name), Urine Test Strips, Reagent Strips, Ketone Testing Strips, or Lipolysis Test Strips. Quick look at ketosis and ketones During ketogenic diet program, glucose is by design in short supply; in this state the liver switches to breaking down the ingested and stored fats as alternative energy source. This metabolic state is called “beta-oxidization.” Ketoacids are the product of beta-oxidization process in our liver. During beta-oxidization the stored or ingested fatty acids are broken down in our liver into our alternative energy source. Our fat stores accumulate fat as “long” fatty acids called triglycerides. While sugar (glucose) is in short supply, the triglycerides are broken down into “short” ketoacids. These short molecules are able to penetrate our cells as fuel. These ketoacids are utilized (burned) by many of our tissues, including the brain. The brain operates just as well on a diet of ketoacids as it does on glucose. What’s left (the incompletely burned fragments) are called ketones. They are what spill into the urine to be removed from the body. Being in ketosis simply means that we’re burning our fat stores and using them as our primary source of fuel. How do ketone test strips work? The test strips provide a quick, private and cost effective way to determine if we are in ketosis at any given time and at what rate. Most of us feel more secure with such a simple way to test, and get instant answer. All we need to do is to simply dip the reagent end of the strip into our urine specimen and remove immediately. Alternatively we can wet reagent area of the strip in our urine stream. We check the color of the reagent area within 10-15 Continue reading >>
Ketosis & Ketone Test Strips
Discuss this article! By Doreen EVERYTHING YOU'VE EVER WANTED TO KNOW ABOUT KETOSIS ... 1. What are ketones? 2. How will ketosis help me to lose weight? 3. But, isn't ketosis dangerous? 4. How do the ketone test strips work, and where do I get them? 5. I'm following Induction strictly; why won't my strips turn purple? 6. Will I lose weight faster if the strips show dark purple all the time? 7. Does caffeine affect ketosis? 8. Will drinking alcohol affect ketosis? What are ketones? Ketones are a normal and efficient source of fuel and energy for the human body. They are produced by the liver from fatty acids, which result from the breakdown of body fat in response to the absence of glucose/sugar. In a ketogenic diet, such as Atkins ... or diets used for treating epilepsy in children, the tiny amounts of glucose required for some select functions can be met by consuming a minimum amount of carbs - or can be manufactured in the liver from PROTEIN. When your body is producing ketones, and using them for fuel, this is called "ketosis". How will ketosis help me to lose weight? Most reducing diets restrict calorie intake, so you lose weight but some of that is fat and some of it is lean muscle tissue as well. Less muscle means slowed metabolism, which makes losing weight more difficult and gaining it back all too easy. Ketosis will help you to lose FAT. Being in ketosis means that your body's primary source of energy is fat (in the form of ketones). When you consume adequate protein as well, there's no need for the body to break down its muscle tissue. Ketosis also tends to accelerate fat loss --- once the liver converts fat to ketones, it can't be converted back to fat, and so is excreted. But, isn't ketosis dangerous? Being in ketosis by following a low carbohydrate diet is Continue reading >>
Reaching Ketosis Comes With Surprises
Atkins, ketogenic and low carb diets dramatically increase fat-burning potential through a special metabolic state called ketosis. Ketosis gives low carbers a metabolic advantage. But keto has other interesting effects that translate into real, rapid results. Low carb and keto FAQ Testing for ketosis The biggest benefits of keto Starting a low carb diet changes your body’s metabolism. On Atkins, ketosis guarantees this weight loss is from fat-burning. Here are the facts about ketosis, how to get there and what to expect. When will you reach ketosis? When we start Atkins, we limit net carbs. Soon, we rely almost entirely on fat and protein for energy. Ketosis starts when carb levels are very low, usually when we eat 20 net carbs or less per day and an average (or less) amount of protein. What Happens During Ketosis? During low carb ketosis, healthy fats are the main source of calories and energy. Even though most of your daily calories are coming from high fat foods, your body burns the fat instead of storing it. What Does Ketosis Feel Like? Ketosis improves energy and lightens mood. The amount of hours you usually sleep reduces with this new energy. Some low carbers notice a sweet smell on their breath. If it becomes bothersome, try a slight increase in daily net carbs. This symptom is typically temporary. How Long Does It Take to Get Into Ketosis? The quickest way to reach ketosis is to limit net carbs: 5 to 20 grams per day – or less than 10% of your total daily calories. Some low carbers eat very low amounts of carbs – less than 5%, to reach ketosis rapidly. Within a few days you should reach ketosis. If results are slow try one of these six ways to speed up ketosis. Keto Testing A measurable way to know if you’ve reached ketosis is ketone testing with strips Continue reading >>
Kicked Out Of Ketosis? The Dirty Little Secret About Ketone Testing Strips
[Some of the links in this post are affiliate links. I might receive a small commission if you purchase something by using one of those links.] Confused about how ketone testing strips actually work? Do you think you've been kicked out of ketosis because they suddenly turned tan? Many low-carb dieters have misconceptions about Ketostix and blood ketone levels, so in this post, we are going to clear out some of those myths and misunderstandings. You'll get the truth about testing strips and learn what really causes those high blood ketone levels. If you hang out at low-carb forums for any length of time, you're bound to hear again and again how someone recently got kicked out of the state of ketosis, and they are looking for a fast way to get back in. Out of all of the issues that you can have with a low-carb lifestyle, understanding ketone testing strips is one of the biggies. “I got kicked out of ketosis,” is one of the most common complaints I hear. And while that may or may not be true, depending on the situation, there are a lot of misconceptions about the role that ketones and ketone testing strips play in a low-carb diet. Even those who are using a blood meter often go by the rumors circulating around the web instead of listening to Dr. Phinney himself. For example: One of the misconceptions I've run into over the years is the idea that ketones are used to fuel the entire body. This is only true at the very beginning of your low-carb diet. When the body first runs out of glucose, the body runs on protein and ketones, but as carbohydrate restriction continues past those first few days, your body goes through a series of steps, or adaptions, that eventually result in muscle insulin resistance. This resistance to the presence of insulin allows the ketones buildin Continue reading >>
Ketosis & Measuring Ketones
Generally, ketone concentrations are lower in the morning and higher in the evening. Whatever time you pick to measure ketone levels, make sure to keep it consistent. Also, do not measure your ketone levels right after exercise. Ketone levels tend to be lower while your glucose levels higher so you won't get representative numbers. Keep in mind there are daily fluctuations caused by changes in hormone levels. Don't get discouraged! Another aspect that affects the level of ketones is the amount of fat in your diet. Some of you may show higher concentration of ketones after a high-fat meal. Coconut oil contains MCTs that will help you boost ketones. To easily increase your fat intake on a ketogenic diet, try fat bombs - snacks with at least 80% fat content. Ketone levels tend to be higher after extensive aerobic exercise as your body depletes glycogen stores. Exercise may help you get into ketosis faster. ketogenic "fruity" breath is not pleasant for most people. To avoid this, drink a lot of water, mint tea and make sure you eat foods rich in electrolytes. Avoid too many chewing gums and mints, as it may put you out of ketosis; there may be hidden carbs affecting your blood sugar. Increase your electrolyte intake, especially potassium. You are likely going to lose some sodium and potassium when switching to the keto diet. Finally, if you find it hard to lose weight on a ketogenic diet, there may be plenty other reasons than the level of ketone bodies: Not Losing Weight on Low-Carb Ketogenic Diet? Don’t Give Up and Read Further. Continue reading >>
Measuring Ketosis: What Are Keto Sticks And Keto Strips?
Ketosis is a metabolic state where the liver breaks down fat to produce ketones. Ketones, on a ketogenic diet, are the primary fuel source for the body. If you’re new to the ketogenic diet and you still have questions, consider reading our Comprehensive Beginner’s Guide to Keto > There are three main ways to measure the ketones in your body, all of which have their advantages and disadvantages. The most common ways to measure are: Blood Ketone Meter. Very accurate but the strips are extremely expensive. Breath Ketone Meters. More accurate than the urine strips, but can sometimes vary in accuracy. Cheaper than blood strips in the long-run. Urine Stricks. This will answer the question “Am I in ketosis?” but will not provide an accurate measure of blood ketones. Scroll down to read a more in-depth analysis of each, and what we recommend for you. Measuring Ketones with Urine Sticks Urine sticks will always be the cheapest and easiest way to measure ketosis. For beginners, this should cover everything you need – there is no point in getting more complex blood strips so early on when you are still trying to understand the nuances of a ketogenic diet. Ultimately, keto sticks are very easy to use – you hold the sticks in your urine stream for a few seconds, and within 10-15 seconds you should notice a color change in the strip (if you are in ketosis). The color of the stick typically is measured in red: light pink being low in ketone production and dark purple being high in ketone production. While keto sticks can be ideal for a general answer to the question “Am I in ketosis?”, they aren’t precise with their accuracy. They measure the acetoacetate in your urine, which is an unused ketone by the body. As you get deeper into ketosis and your body adapts, your b Continue reading >>
Why You Need To Stop Worrying About The Color Of Your Ketostix
Yeah, I know you like to use them, but there are so many misconceptions about what they are telling you, that I need to intervene and make sure you get it. But before I go there, let me urge you to just buy The Art and Science of Low Carbohydrate Living, and read pages 164-165. Phinney and Volek have the best description of this that has probably ever been written, and you should really just read it from them. If I could copy these pages verbatim and paste it here, I would. Seriously, it’s only a few bucks and it’s quite literally the book you want to own if you’re interested in low carb ketogenic diets. OK, while you wait for your book to arrive, let’s dig in… What ketostix measure First off, we need to understand what ketostix actually measure, and more importantly, what they don’t. Generally speaking, ketostix measure excess ketones in your urine. They are considered excess, because they are removed from your serum and shunted to your urine by your kidneys. Their caloric content is thereby wasted. Of the three types of ketones (acetate, acetoacetate, and beta-hydroxybutyrate) produced by your body, ketostix only measure acetoacetate. This is extremely important to understand, because it turns out that your body produces different quantities of these different types of ketones depending on how long you’ve been in ketosis. If you’ve been in ketosis for a while, you’re going to see a reduction in the “intensity” of what you register on your ketostix for two reasons: A change in the relative volume of the ketones produced/present in your body A reduction in the volume of ketones in your urine as your kidneys reduce the amount they secrete Both of these are covered below. Changes in the types of ketones you produce When you first start your ketogenic Continue reading >>
Measuring Ketosis With Ketone Strips: Are They Accurate?
Many people following keto diets want to be in ketosis, a natural state in which the body burns fat for fuel. For this reason, people are curious about whether they are doing enough (via carb restriction) to achieve this state. As a result, ketone strips are a popular tool that numerous people use as a way of measuring ketosis. However, just how accurate are they? And how do they compare to alternate methods of measuring ketones? What is Ketosis? Anyone following a standard high-carbohydrate diet will be burning glucose for energy. However, the body can use both carbohydrate and fat for fuel (1). When carbohydrate intake is very low, the body switches to burning fat for energy. As this happens, our body enters a state of ketosis. Ketosis is a natural biological state during which our body burns fat for fuel. While we are “in ketosis,” our blood levels of ketones—a by-product from the breakdown of fats—rise. Measuring these ketones (also known as ‘ketone bodies’) can, therefore, provide a hint as to how deeply our body is (or isn’t) in ketosis. For this reason, ketone strips—which measure the level of ketones—have become increasingly popular in recent times. Key Point: Ketosis is a biological state where the human body burns fat rather than carbs. What are Ketone Test Strips? For people who want to know if they’re in ketosis, ketone test strips are a cheap and simple way of detecting ketone levels. They are otherwise known as ‘ketone sticks’ and work by urinalysis to tell us the volume of acetoacetate in our urine. If you don’t know what acetoacetate is, then let’s start at the beginning. First of all, there are three types of ketone body; Acetoacetate Acetoacetate is one of the two main ketone bodies, and it is present in urine. We can test f Continue reading >>
Ketone Strip Reviews Which Keto Urine Sticks Are The Best?
If this is your first-time hearing about keto strips as a weight loss product, then you’re probably wondering what in the world they are. Fortunately, we’re here not only to answer that question but to also give you the rundown on how to find the type and brand is the best keto strip today. But first, let’s rewind a bit. To understand what these products do, it’s important to first understand ketosis. This process is the metabolic state in which your liver breaks down body fat. Through this process it produces ketones. During a ketogenic diet, they are your body’s primary source of fuel. What this means is, if you want to lose weight through this process, then these particular bodies are essential to keep your body powering through the challenges of everyday life. As you can imagine, this would make measuring your bodies ketone levels very important during the process of this diet. There are three primary methods of doing so: For more information on choosing the right measurement tool for you and getting the most accurate results possible, you definitely need to keep reading this review.

Keto Sticks (ketone Test Strips)
Keto sticks I’m often asked if it’s necessary to buy and use keto sticks. They’re small test strips that you dip in urine to see if your body is producing ketones (and therefore indicate if you’ve entered ketosis. I already wrote a post about how to tell if you’re in ketosis but I though this topic deserved a separate post. You can buy some here. What’s a keto stick? Like I said, it’s a small test strip and looks like this: It comes in a small bottle that usually contains 50-100 strips depending on the type you choose. It’s very thin and on one end if it there’s a small square of paper (this is the end you dip in the urine). If there are ketones in your urine the little paper will change colour. The darker it is (light pink up to a purple colour) the more ketones are in your urine. On the bottle there’s a picture you compare the colour of the paper to. How do I use a keto stick? It’s very easy: First of all you pee in a clean and dry cup. For convenience you can buy single use plastic cups in a grocery store and keep them in your bathroom. You take a keto stick out of the bottle and make sure you close it firmly again because any humidity can destroy the remaining sticks in the bottle. This is especially important if you store the bottle in your bathroom where there’s steam from the shower etc. Follow the instructions on the bottle when you dip the stick in the urine. Usually you should only dip for 1 second and shake of the excess urine. Not violently though because you probably don’t want to get pee on your hands. Again follow the instructions to see for how long you have to wait until you can read the results. It shouldn’t be long, probably 30-60 seconds. Compare the colour of the stick to the colour on the bottle. Any shade of pink is usu Continue reading >>
