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 >>
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 >>
The Beginner’s Guide To Exogenous Ketones
Have you been wondering what exogenous ketones are? If so, you’re not the only one. The keto-dieting world has been buzzing with information about developments on exogenous ketones for awhile now, with many brands producing exogenous ketones that are used by Keto lifestylers around the world. But the majority of Keto dieters don’t completely understand what exogenous ketones are or how they can benefit their diet (or dieting options). In this post, we’ll provide you with easy to read information about exogenous ketones. With this knowledge, you’ll be able to utilize exogenous ketones in your diet, and teach others about their value. Let’s start with the label! The Definition of Exogenous Ketones Two words: exogenous and ketones. The word exogenous describes something that is developed from external factors; something outside of the usual production. So in terms of ketones, this means that exogenous ketones are synthetic: created outside of your body by scientists and then ingested for accelerated ketosis. We assume that you already know what ketones are, but just in case, we’ll give you a brief description of this term as well. Ketones, are organic compounds produced by in your body when your system experiences starvation, or when you restrict carbohydrates and increase fats, which inhibits a starvation-like state that produces ketone bodies. These ketones are an ideal fuel source for your body and your brain. Studies have suggested that when your body is in a ketogenic state, it utilizes oxygen more efficiently in the generation of energy. In short, ketones are secret weapons for anyone looking to take their body’s fueling system to the next level! To restate the point: Exogenous Ketones are ketone supplements. They’re created outside of your body and i Continue reading >>
Is Ketosis Dangerous?
Duck Dodgers October 14, 2014 Peter, An article by Per Wikholm was published in this month’s LCHF Magasinet, where Per demonstrates that the Inuit could not have been in ketosis given that the scientific literature is abundantly clear, over and over again, that the Inuit consumed too much protein, and more importantly, Per debunks Stefansson’s claims for high fat with writing from his own books—Stef admitted in the pemmican recipes that Arctic caribou was too lean to make pemmican that supported ketosis. The most popular LCHF bloggers in Sweden, Andreas Eenfeldt/Diet Doctor and Annika Dahlquist have reluctantly agreed with Per’s findings—admitting that the Inuit were likely not ketogenic from their diet. I’ve put together a comprehensive review of the scientific literature regarding the Inuit, encompassing over two dozen studies, spanning 150 years, with references from explorers, including Stefansson. In the comments section of that post, Per gives a brief overview of how he was able to prove Stefansson’s observations on high fat intake were flawed. The post is a review of all the available literature that I could find (over two dozen studies). But, the literature certainly does not in any way support ketosis from the Inuit diet due to such high protein consumption. As Per (and Stefansson) points out, the caribou is too lean and as the many quotes show, the Inuit were saving their blubber and fat for the long dark Winter to power their oil lamps and heat their igloos. Again and again, we see that in the literature, as even Stefansson admits this. As far as glycogen is concerned, their glycogen intake is probably not worth scrutinizing given the well-documented high protein consumption in every published study. It really is besides the point. But, interest 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 >>
Optimal Ketone And Blood Sugar Levels For Ketosis
A low carb helps reduce blood sugars and insulin levels and helps with the management of many of the diseases of modern civilisation (e.g. diabetes, heart disease, stroke, cancer, Parkinson’s and Alzheimer’s). We become insulin resistant when our body fat can’t store any more energy. Excess energy is then stored in the liver, pancreas, heart, brain and other organs that are more insulin sensitive. We also see increased levels of energy in our blood in the form of glucose, fat and elevated ketone. Endogenous ketosis occurs when we eat less food than we need. Our insulin and blood sugar levels decrease and ketones rise to supply the energy we need. Exogenous ketosis occurs when we eat lots fat and/or take exogenous ketones. Blood ketones rise, but our insulin levels will also rise because we have an excess of energy coming from our diet. Most of the good things associated with ketosis occur due to endogenous ketosis. Most people following a ketogenic diet over the long term have ketone values lower than what some people consider to be “optimal ketosis”. If your goal is blood sugar control, longevity or weight loss then endogenous ketosis with lower blood sugars and lower ketones is likely a better place to be than chasing higher blood ketones. I have seen a lot of interest and confusion recently from people following a ketogenic about ideal ketone and blood sugar levels. In an effort to try to clear this up, this article reviews blood ketone (BHB), breath ketone (acetone) and blood sugar data from a large number of people who are following a low carb or ketogenic diet to understand what “normal” and “optimal” look like. Many people initiate a low carb diet to manage their blood glucose levels, insulin resistance or diabetes. As shown in the chart below, Continue reading >>
What’s The Deal With Ketostix?
This is a summary/extract from The Ketogenic Diet by Lyle McDonald. Whether correct or not, many ketogenic dieters tend to live or die by the presence of ketones in their urine. The presence of ketosis, which is indicative of lipolysis can be psychologically reassuring […]. However it should be noted that one can be in ketosis, defined as ketones in the bloodstream, without showing urinary ketones. Although up to 100 grams of carbohydrate will allow ketosis to develop, it would be rare to see ketones excreted in the urine at this level of intake. Since the only measure of ketosis available to ketogenic diets are Ketostix ™ carbohydrates must be restricted below this level of ketosis is to be measured. As a general rule of thumb, dietary carbohydrates should be below 30 grams per day for ketosis to be rapidly established and for ketones to be lost in the urine. However, this value varies from person to person and depends on other factors such as protein intake and activity, which allows individuals to consume relatively more carbohydrate without disrupting ketosis. After adaptation to the diet, it appears that individuals can tolerate relatively greater carbohydrate intakes without disrupting ketosis. Although not completely accurate, Ketostix ™ can provide a rough measure of how many carbohydrates can be consumed while still maintaining ketosis. As long as trace ketosis is maintained, carbohydrates can be gradually added to the diet. Since Ketostix ™ only register relative concentrations, rather than absolute amounts, changes in hydration state can affect the concentration of ketones which appear. A high water intake tends to dilute urinary ketone concentrations giving lighter readings. Ketones in the urine simply indicate an overproduction of ketones such that Continue reading >>
An Inconvenient Truth About Ketone Levels
Too many keto "gurus" make bold, one-size-fits-all claims about ketone levels. Learn how to separate truth from myth! If you've been following a ketogenic diet for a while, or spent any time frequenting forums and blogs dedicated to this way of eating, you've probably figured out by now that nutritionist JJ Virgin nailed it: The human body is not a bank account, where you can make precise deposits or withdrawals and know exactly what your balance will be afterward. If only it were that simple! The success stories and frustrated rants on various keto platforms across the internet point to something that should be fairly obvious: People are different. (Shocking, I know!) Two people can eat the exact same number of calories, in the exact same macronutrient ratios, and even eat the same exact foods, yet have completely different ketone levels, energy, and fat-loss results. The widespread existence of keto myths makes adapting and thriving more difficult than it should be for newcomers to keto. Learn the truth about these four common keto myths to calm your ketone (or lack thereof)-induced stress! Myth 1 Higher Ketones Lead to More (or Faster) Fat Loss If there is one myth I wish would die a fiery, painful death, it's this one. Why? Ketone production is the result of lipolysis (the breakdown of fat)—not a direct cause of fat loss. This applies to blood-, breath-, and urine-ketone levels. To further refute this erroneous claim, think about this: It's possible to have elevated ketones and gain body fat. Trust me, you could mainline mayonnaise and nothing else to the tune of 8,000 calories a day and be in ketosis. I wouldn't place a bet on you leaning out much, though. Fat loss doesn't come from being in deep ketosis; it comes from choosing the right foods in the right amount Continue reading >>
Being Fat Adapted Versus "in Ketosis" (pt.1/3)
UPDATE!! (9/20/2017) I have a new post that explains how and why the body produces ketones, It will help you understand much better the difference between burning fat and having a fat-based metabolism, versus being "in ketosis." It's very long, but I think it's worth reading if you'd really like to understand this -- and if you want to stop freaking out about your ketone levels. (If you click over to that post and want to read only the section that explains the difference between ketosis and running on fat, scroll way down to where it says Ketogenesis: How and Why Do We Make Ketones? Also: Fat Adaptation versus Ketosis.) Happy reading! If I never hear or read those six words, in that order, ever again, I’ll be one happy individual. Based on what I come across on low-carb forums, blogs, and videos, there is a lot of confusion about the correct use of urine ketone test strips (which I’ll sometimes refer to as ketostix, since “ketone test strips” is a mouthful, even when you’re only reading). So allow me to ‘splain a little bit about how to interpret these things, and what role they should play—if any—in your low-carb life. First and foremost is the most important thing you will read in today’s post. (And it is so important that I will likely repeat it in all the posts to follow in this little series. Plus, you can tell it’s important because it’s red, bold, in italics, and all caps, hehheh.) You can be in ketosis and not lose body fat, and you can lose body fat without being in ketosis. Here is an exhaustive, comprehensive list of everything urine ketone test strips tell you: There is acetoacetate in your urine. That’s it. Nothing more. Nada más. Game over. Finito. The fat lady has sung, and Elvis has left the building. Your worth as a human being Continue reading >>
How To Detect Ketosis
How can you tell if your low-carbing efforts have been effective enough to induce ketosis? Learn how to check your ketones! The state of ketosis The state of ketosis means that the body has switched from depending on carbohydrates for energy to burning fats for fuel. This means not only dietary fats (olive oil, guacamole, deep-fried pig ears), but also all the jiggly bits around your waist — clearly a desirable state for anyone looking to shed extra weight. When the body metabolizes fat, it generates molecules called ketones (also known as ketone bodies). As you restrict carbohydrate intake and amp up the dietary fat, more fat is metabolized and a greater quantity of ketones are created. Most of the cells in your body — including those in your brain — are able to use ketones for energy, although many people experience a few days’ adjustment period, often called the low carb flu. One of the varieties of ketones generated — acetone — cannot be used by the body and is excreted as waste, mostly in the urine and the breath. Conveniently, this makes it very simple to measure whether or not you are in ketosis. Upon entering ketosis, some people report a distinct change in the smell of their breath as a result of the extra released acetone. It could be “fruity” — it’s been likened to overripe apples — or even “metallic.” If you notice this happening during your first few days of changing your diet, it could be a good sign you’re in ketosis. The unusual smell isn’t anything dangerous, but it could be annoying. Drinking plenty of water should help, or get yourself some sugar-free gum. Most people report “keto-breath” diminishing after the first few weeks. Detecting ketones in urine The more accurate way — and the one we recommend — to check f 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 >>
Monitoring For Compliance With A Ketogenic Diet: What Is The Best Time Of Day To Test For Urinary Ketosis?
Go to: Methods The KetoPerformance study with its before-and-after comparison design was registered at germanctr.de as DRKS00009605 and took place from February to June 2016. Exclusion criteria included underweight, obesity, kidney stones, pregnancy, diabetes mellitus and any fatty acid-metabolism disorders. The study protocol was approved by the Ethics Commission of the Albert-Ludwig University Freiburg (494/14) and all subjects signed a written consent form. Twelve of the 42 subjects from the KetoPerformance study could be recruited for the present substudy. Experimental design and dietary intervention The experimental intervention consisted of a KD without caloric restriction lasting 6 weeks with a previous preparation period including detailed instructions during teaching classes and individual counselling by a dietitian. The subjects were free to follow a KD according to their personal preferences but were advised to reach a ratio by weight of approximately 1.8:1 fat to carbohydrate and protein combined, yielding a diet with 80, 15, and 5 % of total energy intake from fat, protein and carbohydrate, respectively. During the KD intervention's sixth week, our substudy subjects were instructed to measure urine and blood ketone concentrations at regular intervals in as close proximity as possible during a 24-h period from 07:00 to 07:00 in the morning. During the day (07:00 till 22:00) blood and urinary ketones were measured every full hour and every three hours, respectively. During the night, blood and urinary ketones were measured once at 03:00. In total blood and urine and ketones were measured 18 and 8 times, respectively, and were recorded in a table sheet. Subjects were asked to drink 400 ml of water every 3 h during the day to ensure sufficient urination and to Continue reading >>

The Beginners Guide To Ketosis: Investigating Low-carb, High-fat Eating
The only hard and fast rule of health is that health is personal and what works well for one person may not work for someone else. Aside from that rule, there are “frameworks” that seem to benefit large groups of people. One more level down from that are alternative strategies that benefit smaller groups. Ketosis is likely one of those alternative strategies that works well for certain, smaller groups of people. So, right off the bat I want you to understand that Ketosis might not be for everyone. I’m going to lay out the case for potential benefits of Ketosis. If it sounds interesting and beneficial to you, then consider trying it. (see our free cheat sheet to help you). What is Ketosis Ketosis occurs when liver glycogen gets depleted and the body burns fatty acids for fuel. The primary driver of this state is a very low carbohydrate intake. Often, it also requires a low protein, higher fat intake. You can also achieve a state of ketosis by not eating altogether. The creation of ketones is a byproduct of this metabolic state. Ketones are a source of fuel, just as glucose is a source of fuel. Ketones tend to have some added benefits, though. What role does Ketosis play in human health? Ketosis allows our bodies to function in the absence of carbohydrates, both physically and mentally. Instead of burning carbohydrates, or converting protein to glucose, the body burns ketones. This is pretty much a survival mechanism. It allows your body to function in a state of caloric deprivation. This is why ketosis often gets bad press (as it’s linked to “starvation”). Being a survival mechanism doesn’t make it invalid as a strategy, though. There can still be potential benefits to be had. Let’s cover a few of them… Ketosis and Accelerated Fat Loss Being in ketosis Continue reading >>
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 >>
Ketones are a beneficial product of fat metabolism in the body. When carbohydrate intake is restricted, it lowers blood sugar and insulin levels. As insulin levels fall and energy is needed, fatty acids flow from the fat cells into the bloodstream and are taken up by various cells and metabolized in a process called beta-oxidation. The end result of beta-oxidation is a molecule called acetyl-coA, and as more fatty acids are released and metabolized, acetyl-coA levels in the cells rise. This causes a sort of metabolic “feedback loop” which triggers liver cells to shunt excess acetyl-Coa into ketogenesis, or the making of ketone bodies. Once created, the liver dumps the ketone bodies into the blood stream and they are taken up by skeletal and heart muscle cells at rates of availability. In addition, the brain begins to use ketones as an alternate fuel when blood levels are high enough to cross the blood brain barrier. Testing Laboratory Microbiology - Air Quality - Mold Asbestos - Environmental - Lead emsl.com There are three major types of ketone bodies present in the human blood stream when the metabolic process of ketosis is dominant: Acetoacetate (AcAc) is created first β-hydroxybutyrate (BHB) is created from acetoacetate Acetone is a spontaneously created side product of acetoacetate In times of starvation, or a low carbohydrate intake resulting in low insulin levels, ketone bodies supply up to 50% of the energy requirements for most body tissues, and up to 70% of the energy required by the brain. Glucose is the main source of fuel for neurons when the diet is high in carbohydrates. But when carbs are restricted, ketogenesis becomes the primary fuel process for most cells. During fasting or low carbohydrate intake, levels of ketone bodies in the blood stream can Continue reading >>
