Michel Lundell – To Assess Ketosis By Blood Or Breath Testing?
Michel Lundell looks at the differences between measuring ketones via blood and breath when assessing ketosis. Here’s the latest release from Low Carb Breckenridge 2017 conference. Presentation slides are available here to download in PDF format Michel is a Swedish engineer and inventor who suffered his first seizure in 2004 and was diagnosed with epilepsy in 2012. After searching for methods to avoid the side effects of his seizure medication, Michel discovered the ketogenic diet as a means for controlling his seizures. As Michel came to understand the limitations of blood and urine ketone testing, Michel started investigating the analysis of breath ketones and went on to invent the world’s first commercially available breath ketone analyser, the ‘Ketonix’.

Why I Stopped Testing My Ketones On A Ketogenic Diet
On measuring Ketones. Like many people, when I first started a Ketogenic diet in early 2014 I bought the Ketostix and just couldn’t wait to see the color change. And change it did! It was neat, and it provided motivation for me to continue. Eventually, I got a blood meter, a breath meter and spent lots of time (and money) testing ketones. Between a Ketonix Breath Ketone Analyzer, as well as dozens of blood ketone test strips, I’ve probably spent well over $500 testing ketones. The main thing I learned from my extensive ketone testing regimen is that the results vary widely and there’s little application to my goals. Eventually, I stopped testing and here are several reasons why: 1. Burning fatty acids from fat is the main benefit of a ketogenic diet On a ketogenic diet, some of the brain’s energetic demand is fueled by ketones, but the heart, muscles, etc. are fueled by fatty acids. Most of the energy we utilize both at rest and at sub-maximal exertion on a ketogenic diet is fatty acid, not ketones. Quoting Dr. Ron Rosedale on chasing ketones at the Keto Summit: “I don’t want people to have the mindset that it’s the ketones that are the benefit of the diet. They are a beneficial side effect, but the main benefit is that you are burning fatty acids from fat. The more fatty acids from fat you are burning, the less glucose you need to burn. And that’s really where you are getting the benefit…So ketones are great but the term ketogenic diet indicating that the diet is so good because you are generating all these ketones is a misinterpretation of the benefit. The main benefit is that you are burning fatty acids, and as a side effect of burning fatty acids you are producing ketones that your body can burn too!” 2. Urine Ketones aka “peetones” are ridic Continue reading >>

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.

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.

What Are The Optimal Ketone Levels For A Ketogenic Diet?
If you’ve just started a ketogenic diet, then you’ll know that it can be really tough to figure out if you’re doing keto right. Am I eating too many carbs? Too much protein? Should I still be feeling tired? When is the fat burning supposed to start? It’s confusing, and one of the most confusing aspects is what your optimal ketone levels are supposed to be. Unlike most other diets, the ketogenic diet is designed to put your body into a state of ketosis in order to get your body to start burning ketones instead of the glucose that it usually burns when you eat a high carb standard American diet (SAD). But to know whether you’re in ketosis and whether your body has enough ketones circulating for you to use as energy instead of glucose, you have to measure your actual ketone levels and then determine whether they’re high enough for you to be reaping the benefits of the ketogenic diet. If you’ve tried searching for this information already, then you’ll know that there’s some controversy depending on which expert you follow. So in this article, we’ll tell you exactly what the different experts are suggesting are the optimal ketone levels as well as give you recommendations for what ketone levels you should be aiming for depending on your goals with a ketogenic diet. A Few Quick Notes Before We Start… If you’re looking for signs other than testing your actual body ketone levels as to whether you’re in ketosis or not, then please check out this article instead that provides you with signs you’re in ketosis. If you’re a type 1 diabetic, then this article is not for you and the optimal ketone levels suggested below are not applicable to you. Please check out the tons of other ketone level articles on the web to ensure your ketone levels do not reach Continue reading >>

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 >>
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 >>
Ketosense – An Arduino Based Ketosis Detector
In this post I will go through the hardware and software of the instrument I have made. If you are curious to why I have made it, I would recommend that you start reading the other posts I have done about this project and work your way forward. Just click on Ketosis detector under categories. Introduction The instrument´s purpose is to detect the amount of acetone gas that is present in a persons breath. By measuring the amount of breath acetone gas present in a persons breath, it should be possible to determine wether or not a person is in a state called ketosis. Ketosis is, very simplified, when the body runs on fat rather then carbohydrates. If you eat a ketogenic diet, your ketone levels will be elevated. Currently, the only way to monitor your ketone levels are either to take a blood based test or a urine based test, with test strips that changes color depending on the amount of ketons that are present. Both methods work fine but the blood method is very expensive, about 2$ per test, and the urine method is not very precise. Being the curious type of person, and getting inspired by a podcast where Steve Gibson was talking about building an instrument like this, I decided to give it a shot myself. On a very high level, the instrument consists of an electrochemical gas sensor that is sensitive to various types of gases, a combined hygrometer/thermometer and an Arduino Uno board. The electrochemical gas sensor and hygrometer/thermometer has been placed in a plastic case that serves as a ”gas chamber” that you blow into to collect the gas sample. If there is gas present in the air, the resistance of the sensor will decrease. The decrease of resistance is dependent on three factors; gas concentration, humidity and temperature. If these values are known, it is possi Continue reading >>
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 >>
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 >>

Breath Acetone Meters
Acetone is produced when your body is burning fat, and this can be measured in your breath. There are now a growing number of options for measuring your breath acetone. The devices vary wildly in price, and I've found some of the cheaper options can be quite effective. In all cases, how you breathe when taking a measurement is critical to getting a consistent and accurate reading. Overall, I found that measuring breath acetone to be far more convenient, and far more useful than measuring blood ketone levels. Measuring breath acetone is vastly cheaper than blood tests, and obviously less painful. This allowed me to check my ketone levels throughout the day, enabling me to find more detailed information about how my body reacts to food and exercise. The Ketonix is an FDA approved device that is designed specifically as a breath acetone meter. This is the only device that will give you an acetone reading in Parts Per Million, but is expensive and I found it to be cumbersome to use and I've experienced more erroneous readings than with cheaper devices. A cheap breathalyzer can be used as an improvised breath acetone meter. While these devices are intended to measure alcohol intoxication through breast measurement, the cheaper devices also detect acetone. This means you have to get a cheap, low quality breathalyzer, as the better devices will filter out any acetone. (I like the Greenwon AT6000, (Price Not Available)). There's another dedicated breath acetone meter called Ketometer. It's cheaper than the Ketonix, but more expensive than a cheap breathalyzer. LEVL is a remarkably expensive device for measuring breath acetone, and it requires an ongoing subscription. At the time of writing, it's$699 + $49/month, which is too expensive for me to consider. One interesting note is 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 >>
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 >>
