If you’ve been following along with us, then you’ll know that the ketogenic diet—also known as <i>keto</i>—is a high-fat, low-carb lifestyle that helps you shed unhealthy fat, <i>decrease</i> your appetite, and even reduce your blood sugar and insulin levels<sup>1</sup>. In this article, we’ll demystify ketones, teach you how testing the ketone levels in your blood, urine, and breath can level up your keto diet, and share why you should measure your ketone levels and glucose levels together. </p> <p align="justify">Let’s dive in, shall we?</p> <p align="justify">The goal with the keto diet is to maintain a state of <i>ketosis</i>. Carbs and sugars—stored as glucose—are your body’s <i>normal</i> go-to source for energy, but they’re not the only one. Fat from the foods you eat and from your body’s own stores can also be used as an energy source. When you trigger your body to use fat as fuel rather than its glucose stores, you enter into <i>ketosis</i>, an ideal state for losing weight quickly and safely.</p> <p align="justify">In order to reach this state, keto dieters consume the majority of their calories from fat, plus a moderate amount of protein and very little carbohydrates. When the body doesn’t have carbs and sugars to break down into glucose, it has to turn to the fats you consume and store in order to refuel. Ideally, you achieve the perfect balance of fat, protein, and carbs to enter ketosis and stay there.</p> <p align="justify">And that point is crucial. You will only see the benefits of a keto diet if you maintain a state of ketosis during your high fat-burning days. (<i>We promote a 14-day cycle where you’ll eat high fat-burning foods for 12 days and incorporate one cheat day and one <a target="_blank" href="https://www.warriormade.com/content/diet/how-to-use-intermittent-fasting-to-accelerate-your/" rel="noreferrer">intermittent fasting</a> day into the mix.</i>) </p> <picture class="lazy-load"> <source data-srcset="https://d1ghrtdbdq2gkr.cloudfront.net/blog-content/bowl-close-up-eggs-0174.webp" type="image/webp"> <source data-srcset="https://d1ghrtdbdq2gkr.cloudfront.net/blog-content/bowl-close-up-eggs-0174.jpf" type="image/jpf"> <source data-srcset="https://d1ghrtdbdq2gkr.cloudfront.net/blog-content/bowl-close-up-eggs-0174.jpg"> <img src="https://d1ghrtdbdq2gkr.cloudfront.net/blog-content/bowl-close-up-eggs-LR-0174.jpg" class="img-fluid" alt="bowl-close-up-eggs-0174"> </picture> <p align="justify">But how do you know if you’re actually in ketosis or not? </p> <p align="justify">Given that most of us aren’t psychic, we have to rely on testing to see if we’re in the right range. The energy you get in ketosis isn’t from the fat directly, but is a byproduct of fat being broken down by the liver into what are known as <i>ketones</i>. <a target="_blank" href="https://www.warriormade.com/content/diet/the-truth-about-exogenous-ketones-an-inside-look/" rel="noreferrer">Ketones </a>enter into the blood to supply energy around the body, especially in the brain. Using special ketone testing, we can detect how many ketones are in the bloodstream to see if you’re in ketosis. </p> <p align="justify"> With testing available to measure ketones in your blood, urine, and breath right from your own home, finding out if you’re in ketosis is easier than ever. Here we’ll break down all the basics so you know exactly how to measure your ketones at home. </p> </section> <hr class="divider-50 divider-medium mx-auto"> <section id="section1"> <script type="application/ld+json">{"@context":"https://schema.org","@type":"FAQPage","mainEntity":[{"@type":"Question","name":"How to Use a Ketone Meter","acceptedAnswer":{"@type":"Answer","text":"As we mentioned, there are three different types of ketone testing that are available for home use: urine, breath, and blood. #1 Urine testing, #2 Breath analysis, #3 Blood testing"}}]}</script> <h2>How to Use a Ketone Meter</h2> <p align="justify">As we mentioned, there are three different types of ketone testing that are available for home use: urine, breath, and blood.</p> <h3><i>#1 Urine testing</i></h3> <p align="justify">You apply a small sample of urine to a test strip to determine your ketone levels. The trouble with urine testing is that it only measures the amount of ketones that you excrete. When you are just getting started with the keto diet, this will be useful data—if ketones show up in your urine, that means you’re producing ketones. That’s a good sign! But over time, your body gets better at using those ketones for energy, so you pass far less of them through your urine<sup>2</sup>. Eventually this can cause an issue with testing accuracy since low ketone levels in the urine may not reflect actual blood ketone levels. </p> <p align="justify">Still, urine testing is a cheap and reliable option, especially for keto newbies. If you opt for urine testing, look online or check out your local drug store to find test strips, then follow the instructions to get your levels.</p> <h3><i>#2 Breath analysis</i> </h3> <p align="justify">In the same way a breathalyzer can detect blood alcohol level, testing is available to measure the acetone in your breath. Breath <i>acetone</i> is heightened when you’re in a state of ketosis, so testing at higher levels of acetone is a sign you may be in ketosis. The major advantage to this method is that it’s simple, pain-free, and reusable</p> <p align="justify">But there are challenges to this testing method as well. The way that you breathe—including the exhaled volume, pattern of breathing, and breath temperature—can impact the level of acetone in your breath<sup>3</sup>. If you’ve eaten garlic, had caffeine, or exercised recently, these may also tamper with your results. These variables can make testing accurately a challenge.</p> <h3><i>#3 Blood testing</i></h3> <p align="justify">Users place a small sample of blood from pricking a finger on a test strip. A device analyzes the test strip to give a fast readout of the blood ketone levels. Aside from a little pain, blood ketone testing gives reliable and accurate results quickly making it ideal for testing your ketone levels daily.</p> <p align="justify">We recommend using blood ketone testing as it tends to be more accurate. We’ll explain later how blood tests can give you a readout of blood ketones <i>and</i> glucose to get a clear picture of whether we’re in ketosis or not.</p> <picture class="lazy-load"> <source data-srcset="https://d1ghrtdbdq2gkr.cloudfront.net/blog-content/adult-career-clipboard-0174.webp" type="image/webp"> <source data-srcset="https://d1ghrtdbdq2gkr.cloudfront.net/blog-content/adult-career-clipboard-0174.jpf" type="image/jpf"> <source data-srcset="https://d1ghrtdbdq2gkr.cloudfront.net/blog-content/adult-career-clipboard-0174.jpg"> <img src="https://d1ghrtdbdq2gkr.cloudfront.net/blog-content/adult-career-clipboard-LR-0174.jpg" class="img-fluid" alt="adult-career-clipboard-0174"> </picture> </section> <hr class="divider-50 divider-medium mx-auto"> <section id="section2"> <script type="application/ld+json">{"@context":"https://schema.org","@type":"FAQPage","mainEntity":[{"@type":"Question","name":"What Is a Good Ketone Level for Ketosis?","acceptedAnswer":{"@type":"Answer","text":"Your ideal ketone levels will depend on which method you use. For urine samples, your testing strips will generally come with a color-coded key that shows your ketone levels. With breath analysis, breath acetone levels of anywhere from 2 to 40 ppm is an indication that you’re in ketosis.\n\nIf you’ve opted for blood ketone analysis, there are two different ranges of ketone levels that you should look for. If you’re new to the keto diet or are hoping to achieve weight loss, aim for 0.5 to 1.0 mmol/L of blood ketones, a range known as light nutritional ketosis.\n\nFor those who have been at the keto diet for a while or have high weight loss goals, your target is optimal ketosis which occurs at 1.0 mmol/L to 3.0 mmol/L blood ketones. Optimal ketosis is just that: optimal! So aim for the blood ketone level that works with you and your goals.\n\nIt’s important to remember that your blood ketone and acetone levels do shift throughout the day and can be altered by things like exercise, eating, and sleep.

This helps to avoid the dawn effect—the little morning glucose burst we get to help us out of bed—as well as any fluctuations that come up when we eat or drink5. Your blood ketone levels are also at their lowest right when you wake up, so waiting that extra hour before testing helps you get a more accurate result.\n\nIn general, it’s best to do testing several hours after eating or just before your next meal. But the key is to test at a time that you can commit to every single day.\n\nTo start, you may want to do testing twice per day, but once also works.
