How Is Ketosis Measured

How To Test Your Blood With A Home Ketone Meter

How To Test Your Blood With A Home Ketone Meter

testing is used by people with diabetes and by people on a ketogenic diet. You can test your urine or your blood for ketones. But because urine testing is not as accurate, the American Diabetes Association recommends blood ketone testing with a ketone meter as the preferable method. If you have diabetes, you should discuss home blood ketone testing with your doctor to learn whether it is recommended in your case and when you should perform the testing. Ketone testing is particularly important during periods of illness. Blood Ketone Meters for Testing at Home You will need a blood ketone meter and a kit that include the lancet pen and ketone test strips. These meters also will read blood glucose test strips, and both will download their results to your computer. Other brands and models may be available, including: Precision Xtra: This meter from Abbott Diabetes Care can store up to 450 measurements and will display your blood glucose averages over different time periods. You need to enter a code to switch from glucose testing to ketone testing. Users seem happier with the Precision brand, and researchers find it to be the more accurate. The strips require 1.5 microliters of blood. It also features a backlit display. Nova Max Plus: This meter from Nova Biomedical is often provided free with the purchase of two boxes of test strips. You don't have to enter a code to switch it from blood glucose to ketone testing; it does that automatically when you insert a ketone test strip. If you are using it primarily for blood glucose, it will remind you to test for ketones if your blood sugar level is 250 mg/dL or higher. The test strips for the Nova Max are less expensive but also flimsier and give more error messages, requiring retesting. The strips require less blood than the Prec Continue reading >>

First Reusable Breath Ketone Analyzer

First Reusable Breath Ketone Analyzer

The KETONIX has a one time cost and is simple to use. It has never been easier to see if you are producing ketones! Urine strips indicate the excess concentration of acetoacetate in the urine. KETONIX indicates the acetone in your breath . Acetone is produced from the breakdown of acetoacetate in blood. Measurement units are not the same, the concentration of acetoacetate in blood is higher due to less volume (higher density) and is typically measured in mmol/l. The concentration of acetone in breath is lower due to much more volume (lower density) and is measured in PPM. Again, urine strips measures acetoacetate in urine, blood meters measures beta-hydroxybutyrate in blood and KETONIX measures acetone in breath (air). Urine strips can only be used once. KETONIX is reusable and can be used over and over again. Urine strips show a historical value of the excess production. KETONIX shows a real-time value of the acetone level in the blood right now! Urine strips tests need urine and somewhere to do the test. You can perform tests using KETONIX wherever you can access a powered USB port. We don't recommend using KETONIX in vehichles (or in any motion). Urine strips need to be disposed. KETONIX should be stored in the bag that was included with the product. Urine strips cost per test. KETONIX is a one-time investment! Blood ketone meters measures beta-hydroxybutyrate in blood, not acetoacetate or acetone. Blood ketone measure requires strips which are expensive Blood ketone measure sometimes fails and cost you twice! Blood ketone meter values differ between devices, even when it is the same model and brand. Blood ketones acts like a excess buffer of energy that can be used when needed. Acetone is released from acetoacetate, not the blood ketone (beta-hydroxybutyrate). Blood Continue reading >>

Ketone Strip Reviews Which Keto Urine Sticks Are The Best?

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.

Measuring Ketosis With Ketone Strips: Are They Accurate?

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 >>

3 Best Ways To Measure Ketones For Your Ketogenic Diet (review & Buyers Guide)

3 Best Ways To Measure Ketones For Your Ketogenic Diet (review & Buyers Guide)

How do you get accurate readings of ketones? Which methods actually work? These are common questions I going to help you with in this article. Anyone interested in using the latest nutritional research to improve their health has likely heard of a ketogenic diet. Ketogenic diets are a simple way to get your metabolism to prioritize the consumption of fatty acids, also known as ketones, when at rest or exercising. While there is a wide body of research that confirms the benefits of this type of nutritional plan, for the average user at home – one big question remains. How can you measure ketone levels to ensure your body is reaching a perfect state of ketosis? Without an accurate method of ketosis measurement, you will never achieve an optimized LCHF or ketogenic diet. However, it has not always been easy to measure your level of ketosis at home. At least this concern is now a thing of the past, because there are many ways to measure ketone levels easily and accurately in the comfort of your own home. Find out the very best method to test your level of nutritional ketosis that strikes the perfect balance of ease, price and quality. Before getting too deep into the different methods for measuring ketosis, it is important to first look at exactly why measuring them is so important and to clarify some of the more complex scientific terms. Ketone Testing Terminology If you have decided to try a ketogenic diet to achieve nutritional ketosis, then finding an accurate way to measure your ketone levels is important. You need to be able to maintain yourself in the optimal zone where fat is used as energy rather than glucose. Too little ketone and you will not see any positive effects. But higher levels give no real benefit and could indicate a serious problem with your diet. Li Continue reading >>

Breath Acetone Is A Reliable Indicator Of Ketosis In Adults Consuming Ketogenic Meals1,2,3

Breath Acetone Is A Reliable Indicator Of Ketosis In Adults Consuming Ketogenic Meals1,2,3

Abstract Background: Ketogenic diets are used therapeutically to treat intractable seizures. Clinically, it appears that the maintenance of ketosis is crucial to the efficacy of the diet in ameliorating seizures. To understand how ketosis and seizure protection are related, a reliable, noninvasive measure of ketosis that can be performed frequently with minimal discomfort is needed. Objective: The objective was to determine which index, breath acetone or urinary acetoacetate, is more strongly related to the plasma ketones acetoacetate and β-hydroxybutyrate. Design: After fasting overnight for 12 h, 12 healthy adults consumed 4 ketogenic meals over 12 h. Blood, breath, and urine samples were collected hourly. Blood was analyzed for plasma acetoacetate and β-hydroxybutyrate, breath for acetone, and urine for acetoacetate. Results: By the end of the 12-h dietary treatment, plasma acetoacetate, plasma β-hydroxybutyrate, and breath acetone had increased 3.5-fold, whereas urinary acetoacetate increased 13-fold when measured enzymatically and 25-fold when measured with urinary ketone dipsticks. Plasma acetoacetate was best predicted by breath acetone (R2 = 0.70, P < 0.0001). Plasma β-hydroxybutyrate was equally predicted by breath acetone and urinary acetoacetate (R2 = 0.54, P = 0.0040). Conclusions: Breath acetone is as good a predictor of ketosis as is urinary acetoacetate. Breath acetone analysis is noninvasive and can be performed frequently with minimal discomfort to patients. As an indicator of ketosis in epilepsy patients consuming a ketogenic diet, breath acetone may be useful for understanding the mechanism of the diet, elucidating the importance of ketosis in seizure protection, and ultimately, enhancing the efficacy of the diet by improving patient monitoring.

A New Toy Measuring Blood Ketones

A New Toy Measuring Blood Ketones

I just got a new toy: a device for measuring blood ketones. This is a far more exact and reliable measurement than testing for urine ketones using cheap dipsticks. Ketosis is of course the state the body is in when eating very low carb. Ketones, made from fat, will then fuel the brain instead of glucose. So who needs one of these gadgets? Perhaps nobody. Obviously it’s easy to eat LCHF without it. This is for curious nerds (like me) and for those who want definite proof that they are eating so little carbs that insulin levels are low and fat burning is maximized. A ketone level somewhere between 1.5 – 3 is said to be an optimal level for maximizing weight loss. It means that insulin levels are very low. As you can see my first measurement was 0.2, after a caesar sallad dinner. I’m not surprised as I’ve probably eaten at least 50 grams of carbs a day lately. I will try it out fasting in the mornings during the coming days. Perhaps I’ll try being really strict with the carbs for a while to see what happens. Have you tried one of these or are you interested in doing it? Continue reading >>

5 Ways To Measure Your Ketones

5 Ways To Measure Your Ketones

5 Ways to Measure Your Ketones A ketogenic diet is a very low carbohydrate, moderate protein and high fat based nutrition plan. A ketogenic diet trains the individual’s metabolism to run off of fatty acids or ketone bodies. This is called fat adapted, when the body has adapted to run off of fatty acids/ketones at rest. Research has demonstrated that this nutrition plan improves insulin sensitivity and reduces inflammation throughout the body. This leads to greater fat metabolism and muscle development as well as a reduced risk of chronic disease. (1, 2). I get asked all the time how to measure the state of ketosis. There are several major ways and we will discuss those in this article. Measuring Your Ketones There are three types of ketone bodies: Acetone, Acetoacetate and Beta-Hydroxybutryate (BHB). Each of these three can be tested as acetone is a ketone released through the breath, acetoacetate is a ketone released through urine and BHB is (although not technically a ketone it acts like a ketone) in the blood stream and used by the cells for energy. 1. Blood Ketone Meter This measures BHB and is considered to be the most accurate way to measure ketone bodies. These have the ability to determine the ketone level in your blood precisely but they are also pricey and invasive. Personally, I freak out every time I have to prick my finger!! The Precision Xtra blood glucose and ketone meter is a good buy at $28-$30. The expensive part is the ketone test strips here which can cost $4 each. If you are looking at testing yourself every day it is going to cost you $120 a month and the $30 meter. Here is a starter kit you can get on Amazon Most people will enter into a light nutritional ketosis (between 0.5-1.0 mmol/L on the meter) within two or three days. It typically takes Continue reading >>

Tracking Blood Ketones: Behind The Scenes Data On The Ketogenic Diet

Tracking Blood Ketones: Behind The Scenes Data On The Ketogenic Diet

Tracking Blood Ketones: Behind the Scenes Data on the Ketogenic Diet I’ve tried a lot of diets. I first went vegetarian, then slow carb, then gluten-free, then Paleo. I even did a 28-day Chipotle diet, which is exactly as awesome as it sounds. Eventually I found the Ketogenic diet. For me, like for many people in our communities, this all started with a health concern. I was born with a heart condition. It never impacted my life, but it was there, lingering. When I was a junior in college, a few classmates and I were out enjoying late night pizza. Out of nowhere, one classmate suddenly jolted upright and fell off his stool. He died. I found out the next morning it was from a lingering heart condition, not too unlike my own. I started to think about my health a lot more after that. I read about nutrition and started exploring the confusing world of diets. As I learned more and as I became more involved in Quantified Self, I found myself wanting to quantify these diets. That’s what drew me to Keto. It’s the most measurable diet. Quick Summary of the Ketogenic Diet Keto is a high-fat, very-low-carb diet, usually with 70% of calories coming from fat. The idea is to switch your body from using glucose as its primary energy to breaking down fats into ketones for energy. You can measure the macros that you eat and you can measure the ketones in your urine, breath, and blood. In 2013, I did my first experiment with the ketogenic diet. In that experiment, I tracked everything I ate in MyFitnessPal and compared it to other data I was collecting. I found my energy increased, my sleep quality went up (according to my Zeo data), my cholesterol levels improved, and my food cravings went away. However, I also found that measuring everything I ate was a pain, I didn’t really kn Continue reading >>

Measuring Ketones

Measuring Ketones

An important aspect of the Ketogenic Diet is knowing how high your ketone levels are. There are three types of Ketones; beta-hydroxybutyrate (BOHB) which is measured in the blood, acetoacetate (AcAc) which is typically measured in the urine, and acetone which is typically measured in the breath. Measuring Acetone in the breath is becoming a good option, and I believe that this is probably the future of ketone measurement. It's an area of rapid development, and it was not available when I performed my Ketogenic Experiment, so I'm still gathering data. Measuring BOHB is the most accurate, and it's now practical at home using a similar technique to measuring blood glucose, but it's really expensive at several dollars per test. The easiest and cheapest technique is to measure AcAc in the urine using a test strip. However, this approach is too inaccurate to be useful. Acetone levels correlate well with body fat loss[1], but are also elevated by the Ketogenic Diet[2], MCT [3] intake, and exercise[4] even in the absence of weight loss. One study found that a one pound (0.5 Kg) per week fat loss correlated with 1.7 PPM of acetone (67 nmol/L). Each ~40% increase in breath acetone was an additional ∼0.5 Lb (250g) of weekly fat loss[5]. Breath acetone correlates well (though not linearly) with blood (BOHB) ketone levels[5]. This makes it useful for monitoring the progression of a ketogenic diet, as well as for measuring weight loss. The formula below was developed based on 12 adults consuming Ketogenic meals over a short period[6]: For Breath Acetone (BrAce) in mmol/L: BOHB = 0.11 * BrAce0.47 - 0.18 Note that the relationship is far from exact (r=0.5 or so.) Breath acetone levels can vary dramatically, with healthy individuals on a regular diet having less than 1 PPM (parts per 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 >>

Ketosis & Measuring Ketones

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?

How To Measure Ketones And Optimize Ketogenic Diets

How To Measure Ketones And Optimize Ketogenic Diets

The problem with diets is that we think that one diet should be good for everyone. But research and N=1 experiments show that’s not the case. Learn about measuring ketones and ketosis to understand how your low carb or high fat diet is really affecting you. If there is one area of our bodies that is debated to extremes, with literally hundreds of differing strong opinions on it, it’s nutrition. For many, beliefs about nutrition and diet are tribal. We put ourselves in different camps and we war agains the other camps. Whether it be paleo, low fat, low carb, Atkins, high fat, low protein, vegan, raw vegan and so on. It’s exactly this sort of area where I see data as essential. Without data we have no hope of cutting through the maze of opinions to get to what really works. Part of the problem with nutrition and diets is that we tend to think that one diet should be good for everyone. But increasingly, research and N=1 experiments, are showing that that isn’t the case. And this is exactly why you should pay attention to today’s show. Today, we’re looking at what has relatively recently become the fastest growing nutrition or diet trend. The high fat diet. Also known in different guises as the ketogenic diet, or the low carb diet. And specifically how this can affect our different individual biochemistries, how we can measure “Ketosis” and other biomarkers to understand how our specific biology is reacting to it… and allowing us to troubleshoot and course correct when it isn’t getting the desired results we’re looking for from it. Today’s guest is Jimmy Moore. In 2004, Jimmy, at 32 years, weighed 410 pounds. Since then he has transformed his own biology, shedding all that additional weight with low carb and ketogenic diets. He has also interviewed n Continue reading >>

Why You Need To Stop Worrying About The Color Of Your Ketostix

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 >>

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 >>
