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 >>

False-positive Breath-alcohol Test After A Ketogenic Diet.

False-positive Breath-alcohol Test After A Ketogenic Diet.

Abstract A 59-year-old man undergoing weight loss with very low calorie diets (VLCD) attempted to drive a car, which was fitted with an alcohol ignition interlock device, but the vehicle failed to start. Because the man was a teetotaller, he was surprised and upset by this result. VLCD treatment leads to ketonemia with high concentrations of acetone, acetoacetate and beta-hydroxybutyrate in the blood. The interlock device determines alcohol (ethanol) in breath by electrochemical oxidation, but acetone does not undergo oxidation with this detector. However, under certain circumstances acetone is reduced in the body to isopropanol by hepatic alcohol dehydrogenase (ADH). The ignition interlock device responds to other alcohols (e.g. methanol, n-propanol and isopropanol), which therefore explains the false-positive result. This 'side effect' of ketogenic diets needs further discussion by authorities when people engaged in safety-sensitive work (e.g. bus drivers and airline pilots) submit to random breath-alcohol tests.

A Detailed Guide On How To Test Your Ketone Levels

A Detailed Guide On How To Test Your Ketone Levels

I have to be honest with you. I’ve been making some critical mistakes. I was assuming that I was in ketosis for months but I’m now finding out that isn’t the case. Not even close. I’ve finally hunkered down and have been measuring my ketones the right way and the results have been pretty surprising. I was eating too much protein, and too little fat. I was eating too frequently. I was eating too few calories. I never would have known this without testing. Time for you to learn from the mistakes I made and test the right way. Ketosis can be a powerful nutrition approach to use switch your metabolism to prioritize for fat loss, mental output, physical performance, and much more. The main problem? Many people just assume that if they are “low carb” they are in ketosis, but think again. How do you know if you’re actually in ketosis? As I love to say, “test, don’t guess” when it comes to your health. (Still trying to get “track, don’t slack” to catch on…) I’ll outline in this article the three ways to test your ketone levels and which you should be doing when. HOW TO TEST YOUR KETONE LEVELS: THREE DIFFERENT WAYS There are three testing methods because there are three forms of ketones in your body: acetate, acetoacetate, and beta-hydroxybutryate. Each of these ketone bodies do slightly different things and are in different forms, so they can be tested individually with different methods. The three different area these ketones exist in your body are your breath, urine or blood. The good news is that all of these ketone level measurements can be done at home, by yourself. You don’t need to go to a lab or use any fancy high-tech gadgetry. Tracking consistently, at least when you’re getting used to a ketogenic diet, is important so you know how mu Continue reading >>

My Experience Testing Blood Vs. Breath

My Experience Testing Blood Vs. Breath

I’ve been testing my blood for about 4 months now. After learning of a breath testing analyzer available for sale through Ketonix, I took the leap and ordered one for myself all the way from Sweden. I ordered the sport version, which is red. You can read about the difference on the Ketonix website as they explain it far better than I could! I have continued to test my blood, then use the Ketonix immediately after to see whether the two are consistent. The breath analyzer does not provide a numbered result, but instead flashes different colors to tell you whether you are have little to no acetone in your breath (blue), a small amount (green), moderate amount (yellow), or high levels (red). When my ketone levels as measured by my blood are hovering around 1.0 – 1.4 mmol, the breath analyzer flashes yellow. Yesterday I had a 3.9 mmol result from testing my blood (my highest ever and I’m still not sure why), the breath analyzer registered red, signaling a high level of acetone in my breath. For me, the correlation is good enough between breath and blood. They are measuring different things (beta hydroxybutyrate vs. acetone in your breath) so the results aren’t going to be exactly the same – it’s like comparing apples to oranges. The best part is how easy it is to use. You simply exhale into the analyzer and wait for a color to register. I’ll probably continue to test my blood periodically as that is one way I gauge how different foods affect my ketone levels, but the Ketonix will be my daily tester. Aside from the high up front cost ($149 plus shipping), you will save a lot of money in the long run as compared to purchasing ketone blood testing strips that cost close to $5/piece and are very sensitive to error (I’ve ruined about $50 worth inadvertently over Continue reading >>

The Best Ketone Meter For Monitoring Ketosis

The Best Ketone Meter For Monitoring Ketosis

If you're on the ketogenic diet, measuring your ketone levels is crucial to make sure your body is actually in ketosis - otherwise, you're basically just leaving things up to chance. We spent roughly five days researching ketosis meters in order to find the most accurate monitor for measuring ketone levels, and after reviewing 20+ options, we've found the Precision Xtra to be the best ketone meter available. Using a light prick of the finger, it measures ketone levels using your blood, collecting nearly-exact numbers to help you manage your diet better than any other testing method. You will also need a set of ketone test strips to get started, which can be a little expensive, but we consider this a small price to pay when you're investing in your health. If you’re following the ketogenic diet, you probably already know how it works – low carb, high fat. By eliminating carbohydrates (our body’s main energy source), you’re manipulating your body to move into a state of ketosis, where it burns fat for energy instead of carbs. Maintaining ketosis is relatively easy if you stick to the core principles of the diet (60-70% fat, 20-30% protein, 5-10% carbs), but at the end of the day, you still don’t know for sure if your body has successfully made the transition. Instead, regularly using a ketone meter (also called a ketosis meter) is the preferred way to ensure your blood-ketone level consistently stays within the optimal range for ketosis. There are three main types of ketone meters: blood ketone meters, urine strips, and breath analyzers. Urine strips and breath analyzers work exactly as their names imply – one measures ketone levels using your urine, the other measures them using your breath. Blood ketone meters, on the other hand, work like a blood-glucose me Continue reading >>

7 Tips To Get Into Ketosis

7 Tips To Get Into Ketosis

And convert fat into energy. By Franziska Spritzler, RD, CDE Ketosis is a normal metabolic process that provides several health benefits. During ketosis, your body converts fat into compounds known as ketones and begins using them as its main source of energy. Studies have found that diets that promote ketosis are highly beneficial for weight loss, due in part to their appetite-suppressing effects. Emerging research suggests that ketosis may also be helpful for type 2 diabetes and neurological disorders, among other conditions. That being said, achieving a state of ketosis can take some work and planning. It’s not just as simple as cutting carbs. Here are 7 effective tips to get into ketosis. 1. Minimize Your Carb Consumption Eating a very low-carb diet is by far the most important factor in achieving ketosis. Normally, your cells use glucose, or sugar, as their main source of fuel. However, most of your cells can also use other fuel sources. This includes fatty acids, as well as ketones, which are also known as ketone bodies. Your body stores glucose in your liver and muscles in the form of glycogen. When carb intake is very low, glycogen stores are reduced and levels of the hormone insulin decline. This allows fatty acids to be released from fat stores in your body. Your liver converts some of these fatty acids into the ketone bodies acetone, acetoacetate and beta-hydroxybutyrate. These ketones can be used as fuel by portions of the brain. The level of carb restriction needed to induce ketosis is somewhat individualized. Some people need to limit net carbs (total carbs minus fiber) to 20 grams per day, while others can achieve ketosis while eating twice this amount or more. For this reason, the Atkins diet specifies that carbs be restricted to 20 or fewer grams per Continue reading >>

Measuring Ketosis: What Are Keto Sticks And Keto Strips?

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 >>

Using Ketonix Breath Testing For Nutritional Ketosis Review

Using Ketonix Breath Testing For Nutritional Ketosis Review

If you have been a reader of the site before, you’ll know that I used the concepts from the Bulletproof diet and a lot Bulletproof coffee to help put me into nutritional ketosis and lose a bucket load of weight. That sent me down the should I be checking for ketones, but also thinking well if I’m eating (and drinking) so much saturated fat have I reached and maintained a level of nutritional ketosis? I really wanted to know too as nutritional ketosis (not diabetic ketosis!!) is meant to be the place where your brain is meant to work better. It is also the place where, if you do suffer epileptic seizures, that it helps to reduce the frequency of them. Now I don’t have epilepsy, but I do like the idea I am helping my central nervous system function at a better state. That is another reason why I experiment with and do take various supplements, like unfair advantage, adaptogenic herbs and nootropics for the brain. (more on those to come) Use “BIOHACKER” to get a discount at checkout – valid until the end of July 2017. Blood Vs Breath Ketones Testing I think a lot of people try guess when they have hit the magical place called nutritional ketosis. However, we learnt from ketone researcher Dr Brianna Stubbs interview that the three ways to measure ketone levels are using either blood strips, urine testing strips or breath acetone levels. Measuring acetone levels in your breath is the new kid on the block for testing ketone levels.. Now I think that is awesome not having to prick or finger all the time and also saving on not buying ketone strips from a pharmacy. Why Acetone Breath Levels Are Best Listen to Michel Lundell’s interview on episode 14 of the Biohackers Lab podcast. He explains from his tests why he feels measuring breath acetone levels is better than Continue reading >>

How To Use The Ketonix Breathalyzer

How To Use The Ketonix Breathalyzer

A few months ago, I received my first keto breathalyzer and would like to share my thoughts on this device. The creator of the Ketonix breathalyzer, Michel Lundell, also runs a website to help and support people who use the device for measuring their ketone levels. The price of Ketonix is $ 149 (or $ 169 with the battery). You can buy the Ketonix breathalyzer at Ketonix.com. I was given this device free of charge and I'm not affiliated with Ketonix. The opinions expressed and photos in this post are my own. Measuring Ketones in a Nutshell Before I get to details of how to use the Ketonix breathalyzer, I'd like to start with some basic facts. There are 4 ways to measure your ketone levels: Ketostix. It measures urinary ketones (acetoacetate), is inexpensive but inaccurate because it only measures "wasted" ketones in your urine. In fact, once you get keto-adapted, you may not be able to measure any. Blood Ketone Meter. It measures beta-bydroxybutryate (BHB) and is the most accurate method of measuring ketones (although BHB is not technically a ketone). The drawback is that the strips are fairly expensive, especially if you measure frequently. Observation and following a healthy ketogenic diet. In my opinion, if you don't follow a keto diet for therapeutic purposes (or for performance enhancement), you don't need to measure your ketone levels. In fact, you don't need to follow a very low-carb diet to lose weight. What matters is finding your personal carb intake and also consider other factors that I explained here. Breathalyzer (Ketonix). It measures acetone (acetone is made from a break down of acetoacetate). It's great value for money as it's a one-off payment, there is no need to buy expensive strips and it's accurate enough to tell you whether or not you are in nutrit 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.

The First Disposable Breath Ketone Test Has Arrived

The First Disposable Breath Ketone Test Has Arrived

Do you want a simple way to check for ketosis, without a urine or blood test? It’s also possible to check you breath for ketones (acetone). This has already been possible for some time with the Ketonix reusable breath analyser (costing $149). Now the Ketonix is joined by the just-launched disposable test Metron, which can be ordered via Amazon ($28 for 10 tests). Metron is cheaper if you only want to do a few tests (up to 50 tests), but the reusable Ketonix is cheaper if you want to do more tests than that – testing is free once you have one. At some point we may do a test of Ketonix vs. Metron. Would you find that interesting? Or do you already have your own experience comparing these two devices? Please leave a comment.

How To Know If You’re In Ketosis: A Guide To Testing Ketone Levels

How To Know If You’re In Ketosis: A Guide To Testing Ketone Levels

Ketosis can be a powerful way to use your metabolism for fat loss, mental output, physical performance as well as many other health benefits. But how do you know if you’re actually in ketosis? As the old adage goes “test, don’t guess” when it comes to your health. In this guide, we’ll show exactly how to test your ketone levels to know if you’re in ketosis so you can make sure you’re getting all of the benefits that ketosis has to offer. There are three primary forms of ketones in your body, acetone, acetoacetate, and beta-hydroxybutryate. Each of these compounds do different things in the metabolism of ketosis and can be tested individually with differing techniques. Not all measurement is created equally, however, and some can be better than others for different purposes or times. The three different ketone bodies can be measured when they spill over into three different areas of your body: your breath, urine or blood. The good news is that all of these ketone level measurements can be done at home, by yourself. You don’t have to go to any lab or use any fancy high tech equipment. Tracking diligently, at least when you’re getting used to ketosis based diets, is important so you know how much you react to different variables like exercise, type and amount of food, and amounts of exogenous ketone supplements. Also, the optimal level of ketones for specific goals can vary per person. Knowing the amount where you thrive in the goal you want to achieve (and consistently checking if you’re hitting that amount) is the fastest way to reach your goals. Testing levels of ketones with urine strips (acetoacetate) One of the ketone bodies, acetoacetate, can be measured directly in the urine if they are in excessive levels. The way metabolic substrates get into Continue reading >>

Ketones: Introduction To Testing Ketones

Ketones: Introduction To Testing Ketones

We’ve all had the question, or been asked the question: how do I know when I’m in ketosis? Should I feel different? Should I have increased mental clarity and focus? While one could give a case-by-case, yes-or-no type response for these questions, the best way is to simply test it out. The problem is that most of us don’t have access to a lab 24/7. Due to this issue, we have three possible ways to test ourselves for ketones from home, namely, urine strips, blood meters, or breath meters. Urine Test Strips There are numerous brands of urine strips to choose from if you decide to go this route and they can be easily obtained at your local drug store or online for a relatively inexpensive price. They can cost anywhere from $9-$20 for about 100 test strips. While this would seem to be the easiest way, it may not be the best way. Urine strips are coated with a chemical that reacts to the presence of acetoacetate (one type of ketone body). However, urine by definition is a waste product. So, while having ketones present in the urine may be a great indication that you are producing them, it could also mean that you are not utilizing them effectively. Also, we tend to see that individuals who have been on the diet for a long period of time and/or individuals that are leaner tend to show lighter or smaller traces of “ketones” on the strips compared to people starting the diet or who are significantly overweight. For this reason, this testing method may be great to let yourself know that you are on the right track with your ketogenic diet but it may not be the best way to know one you are keto-adapted. Blood Meters For a more reliable method of measuring ketones, a blood meter may be the way to go. Diabetics are familiar with the concept, as most glucose meters can also Continue reading >>

My Ketonix Has Arrived (updated)

My Ketonix Has Arrived (updated)

Last updated on April 14th, 2017 Unboxing of my Ketonix 2015 I opened the mailbox today to find that my Ketonix 2015 Blue had arrived from Sweden. The arrival of a new gadget is always a cause for celebration. In this case, I was also relieved. I ordered the Ketonix via the company’s website on April 23, selecting the regular “letter” type shipping, so I figured it would take a while to get here. But as the days, and then the weeks, went by, I started to wonder. It’s a long way from Sweden to Michigan (as my great great grandparents discovered). Anything could happen to a little box. But the Ketonix 2015 got here in one piece and in working order. Yes, I took a chance ordering it to be shipped by regular mail, as Anita casually pointed out a couple of times, but it all worked out. Just call me Lucky Jim! I have no commercial interest in the company, nor any affiliate relationship, and paid the full retail price, which is $149 for the Ketonix 2015 model. The regular (lowest cost) shipping was another $10. The Ketonix is more expensive than a blood ketone monitor, but unlike the blood monitors, you can use the Ketonix repeatedly without the need for pricey test strips. Also, you don’t have to keep pricking a finger to draw blood. Initial Impression The Ketonix measures acetone in your breath. A high acetone level is an indicator that your body is using ketones for fuel, which means it is, or could be, burning body fat. Set up is easy. You download a small program to your computer, create a simple profile, plug the Ketonix into a USB port, give it a few minutes to initialize, click “start,” and then blow (exhale) into the unit. My first blow indicated a high acetone level (color-code red), which correlates with a state of ketosis. Anita tried it, and blew a m Continue reading >>
