WHY BREATH? WHY LEVL?
SIMPLE. NON-INVASIVE. ACCURATE. INSIGHTFUL.
LEVL has built a transformative device to non-invasively measure acetone, a by-product of fat metabolism, in exhaled breath allowing you to see the effects of your nutrition choices in real-time. By providing a single breath sample to this FDA registered device, up to two users can make unlimited measurements to calculate, monitor, and predict fat loss. This measurement closes the feedback loop to ensure you are quickly reaching your goals. Unlike urine and blood, the LEVL device measures low levels of ketones as the body shifts into an elevated fat burning state making it a useful tool for any diet.
- Designed to measure high levels of ketones (ketogenic diet or ketoacidosis)
- Unable to measure low levels of ketosis

Elevated fat metabolism or “Keto” (shorthand for ketosis) is the state in which our bodies break down fat molecules for use as energy. By living a ketogenic lifestyle, an individual trains their body to burn fat rather than carbohydrates, which is known in the keto community as becoming “fat-adapted.” Simply put, your body loves carbs because they’re the simplest source of fuel. Significantly reduce or eliminate carbohydrates from your diet, and the body will turn to its next best option: fat. Like the paleo diet, this means consuming high protein, full-fat foods with little processing or added sugars. Sound like a pretty delicious way to lose weight? That’s because it can be! Once you kick carbs and chemically altered “fat-free” foods to the curb, your body’s metabolism will begin to become fat-adapted. Combined with the right exercise plan, you have a recipe for long-term wellness and healthy fat loss.
Based on scientific research, a breath measurement of 2PPM or greater indicates an elevated state of fat metabolism that should correspond to a loss of at least ½ lb. of body fat per week (based on a calorie restricted diet). Learn more from LEVL Clinical Scientist Joe Anderson, Ph.D.
Are you retaining water? Have you lost muscle? Or are you actually burning fat? There are a lot of things affecting us every day that a single number on a scale can’t tell you, and it can get frustrating to switch things up, then “wait and see” only to discover a certain routine isn’t working. By measuring and tracking your daily fat-burn from the inside, you can begin to paint a picture of your body’s reaction to food and exercise in real time, long before outward signs of fat-loss become noticeable. This means that instead of repeatedly going back to the drawing board, you can begin to predict how changes in routine will affect fat-loss. Much more transparent, right? We like it that way.

PPM is an abbreviation that means of Parts Per Million. The LEVL device is measuring PPM of acetone in exhaled breath.
While the goal for elevated fat metabolism is 2PPM, acetone concentrations in healthy individuals can range from roughly 1PPM to 100PPM.
While the human body is always burning a little bit of fat, you are primarily burning carbs and sugars in this zone.
Your body has entered an elevated state of fat metabolism. Based on the scientific literature, 2.0ppm achieved with calorie restriction equates to ½ lb of body fat burned per week (if this level is maintained throughout the week).
While there is not a one-to-one correlation to blood ketones, 8.0ppm is the approximate equivalent of 0.5mmol of beta-hydroxybuterate also known as the beginning states of nutritional ketosis.
For measurements above 10.0ppm, the KCAL/DAY and FAT LBS/DAY will not calculate in the LEVL app. These higher levels are not achieved by calorie restriction alone. Individuals are eating a low carbohydrate diet, consuming ketogenic supplements (e.g., ketone esters or MCT), and/or fasting. Thus, calculating fat loss is difficult because calorie restriction (without fasting) is not the primary driver of breath acetone.*
Higher numbers are not always better.
Experiment with your nutrition, exercise and sleep duration to learn where you feel best.
*For measurements above 10.0ppm, the rate of fat loss is unknown per the scientific literature. People who have measurements above 10.0ppm are typically on a low carb, high fat diet, so they are burning a mixture of stored body fat and nutritional fat therefore the calculation will no longer be relevant.
To measure your breath acetone concentration using LEVL, all you have to do is exhale into the handheld breath pod, where your composition is collected by our patented nanosensor. Once you place the pod back in the LEVL dock, the device will analyze your acetone concentrations down to a single PPM, and sync to the smartphone app where trends are tracked and assessed to give you smart fat-loss predictions. It’s not only effortless and highly accurate, but pretty cool.
At least one measurement a day is recommended, and there is no limit to the number you can take in a day. The LEVL device measurements offer a snapshot of your ketosis over the last 24 hours. The more measurements you take, the more you know about the effects of your wellness choices.
What you eat, how you sleep and the way you move all affect your body’s fat-burning chemistry. Beyond food intake and exercise, variables like hydration, sleep and even stress can have a measurable effect on your fat metabolism. Some easy first steps to take in order to move the needle on your LEVL may be to:
- Cut added sugars and artificial sweeteners from your diet
- Eat healthy fats to lose fat
- Watch your portions
- Add vegetables to every meal
- Increase exercise duration and/or intensity
- Get plenty of sleep
- Stay hydrated
When your body increases the amount of fat it uses for energy relative to the amount of carbohydrates, your breath acetone concentration ramps up. This increase happens over the course of 3-7 days, until you reach an elevated level of breath acetone. Use the LEVL device to monitor how diet and exercise are impacting acetone in your body so you can be sure you’re burning the maximum amount of fat. If your diet becomes high in calories or high in carbohydrates, your body will become less dependent on fat for energy. This will result in an acetone concentration reduction over the course of 1-2 days.
A LEVL device measurement gives a snapshot of the last 24 hours so measurements will not change drastically during exercise. Our scientific data does show that when the body is using fat as its primary fuel source (vs. carbs) during exercise, the LEVL device measurement may drop immediately after intense exercise.
With the optional LEVL smartphone app, every measurement you take can be automatically uploaded from your device via Bluetooth. There, your trends become a roadmap to your optimum health plan.
For measurements between 1 and 10 ppm, the app provides insights in to k/cals of fat burned and pounds of fat burned per day (based on a mixed macronutrient diet).
Much easier than keeping a notebook!
