Get ready. You're about to get the most helpful device for your health and fitness goals: the Lumen Metabolism Tracker. It detects your carbohydrate versus fat-burning capabilities by analyzing your breath and providing personalized nutrition recommendations.

But does it work? Can you trust the results? In this review, we'll examine the Lumen Metabolism tracker and how it can benefit your health journey.

What is the Lumen Metabolism Tracker?

The Lumen Metabolism Tracker is a small, hand-held device that measures your metabolism by analyzing your breath. It uses RER (Respiratory Exchange Ratio) technology to determine the ratio of carbon dioxide and oxygen in your breath, indicating whether you are burning carbohydrates or fat for energy.

To use the device, you breathe into it through a mouthpiece. The data is then sent to the Lumen app on your phone, which displays your metabolic state as either "fat burn" or "carb burn."

Lumen's device is a high-tech breathalyzer. The main metric it gives you is the Lumen Level - a score that shows if your body uses fats or carbohydrates for energy.

Why do you need this? The goal is to efficiently shift between using both types of energy fuels - which is called metabolic flexibility. If you reach that state (meaning, if you use Lumen metrics to adjust your meal plan or workout), your body can use high-carb and high-fat foods for energy without causing weight gain.

The result is increased fat burning, more energy, and weight loss with no incisions, no pain, and (likely) no pills. Plus, you don't have to wear anything all day; the device only takes a minute or two to use.

Who Is It For?

Lumen is for anyone who wants to improve their metabolic health and overall well-being. It can be particularly useful for those looking to lose weight, increase energy levels, or optimize their workout performance.

It is also a valuable tool for anyone with conditions such as diabetes, where monitoring and regulating metabolism is crucial.

Many people say they have a slow metabolism or are "carb sensitive." the reason might be bad nutrition habits or not knowing your body properly. Lumen can help you understand your body's unique metabolic response and guide you toward making appropriate dietary choices.

What Do You Need to Put a Metabolism Tracker Into Work?

Simple - you need the device and the app which shows everything that the device detects. When you order your Lumen Metabolic Tracker, the device and all the supporting accessories come in the pack, while the app is available both for iOS and Android.

The Device

Lumen's metabolic tracker looks like a vape with a strange head. You will use the device to blow into. Before using it first, charge it and then sync it with your app.

The device is fully charged when it indicates a green light while being cradled in the docking station.

When you turn it on and sync with the app, you receive detailed instructions on how to use it, including when, how long, and how strongly to breathe into the device.

It's not recommended to share the device with a family member. When you think the device is dirty, you should wipe down the metallic mouthpiece with an antibacterial wipe, as washing it with water may damage the sensors.

The App

Before you start the process, you need to connect the app to your phone via Bluetooth. The first time you log in, you will receive a survey about lifestyle, physiology, and other health-related specifics.

Further, the app shows you detailed instructions on how you should use the device. A little bouncing ball appears on the screen while you inhale. The app gets to the center of the circle when you breathe right, and it goes out of it to show you you need to stop breathing, continue inhaling, etc.

There are logging options, including "before eating," "after eating," and "custom. When you finish exhaling, the app asks you questions like your diet the day before, what you slept the night before, etc.

If you consistently check and breathe, this will ensure a high level of accuracy in your results. You can also set reminders on the app to remind you when it's time for your next breath test.

Which Metrics Does Lumen Provide to You?

If you use the Lumen Metabolic Tracker correctly, which requires discipline, time, patience, and attention, you will gain tons of valuable information—metabolism rates, recommended diet, metabolic flexibility score, and much more!

Note that you get as much from the Lumen Tracker as you are ready to consistently invest in the process. Also, the more often you complete breath tests and log information into the app, the better you will understand your body's metabolism.

Here are the key metrics you get when properly using Lumen's device and app.

Daily Measurements

Lumen score (1-5) is your most important metric that you should pay attention to every day. It is a representation of your body's metabolic flexibility and can range from 1 (burning fat) to 5 (burning carbohydrates). The middle score, 3, shows you balance between fat and carbs burning. 1 and 2 show that you are using more fat for energy while 4 and 5 indicate that your body is relying on carbohydrates.

Flex Score

The Flex Score starts appearing after 15 days of using the Lumen Tracker. It represents how flexible your metabolism is. The higher the score, the more easily your body can switch between using fat and carbs for energy or the better your body works with what you're eating.

The Flex Score varies from 0-21, where:

  • 0-6 (Low metabolic flexibility)

  • 7-14 (Medium metabolic flexibility)

  • 15-21 (High metabolic flexibility)

The Flex Score and the Lumen score can help you understand how your metabolism responds to different foods and lifestyle choices. By tracking these scores over time, you can make better decisions for your health and fitness goals.

Meal Recommendations

When your test results are ready and provide information about your Lumen and Flex scores, the app will also give you personalized meal recommendations. These recommendations are based on your body's metabolism and can help you improve your metabolic flexibility over time. They include specific food suggestions and information on when to eat certain foods for optimal results.

You can receive recommendations for the maximum number of grams of protein, fat, and carbs you should ingest. Meal suggestions are provided in the form of recipes, making them easy to include in your daily meals.

You can also simplify the health-tracking process by connecting the Lumen app to Apple Health, Google Fit, or Garmin IQ accounts if you have any.

How Does Small Device Determine Your Metabolism Metrics? 

Lumen's small device does what's done in laboratories and clinical settings for decades - but with bulkier equipment. The device has a single-use NA sensor that measures the concentration of the CO2 in your breath. It uses the respiratory exchange ratio (RER) metric, which is scientifically proven and recognized as a reliable method to determine your body's metabolism.

The device measures the relative concentration of carbon dioxide in your breath because this correlates to the relative percentage of fat and carbohydrates you burn for energy.

Previously, if you went to a laboratory for this test, you would wear a mask, breathe in for a few minutes, and then analyze the collected air. Lumen's small device uses the same principle but more conveniently—you breathe into the device for 10 seconds, and it samples your breath and analyses it on its own.

Why Can You Trust Lumen Metabolism Tracker? 

The people behind it have a history of research and development within the field of nutrition and metabolism when it comes to Lumen. The device is created by twin sisters and Ironman triathletes, Merav and Michal Mor. Both have PhDs in Physiology and Nutrition and have years of experience in the field. This means that the device is backed by extensive scientific research and expertise.

How to Get Most of Lumen Metabolism Tracker Results? 

Technically speaking, your goal is to improve your metabolic flexibility score shown in the Lumen app, but it can't be done with occasional briefings and half-hearted attempts. The key to success with Lumen is consistency and patience.

Be Consistent

One of the most important aspects to keep in mind is being consistent with using your Lumen device. In order for it to accurately track your metabolism, you need to use the device daily and at similar times each day.

It needs sufficient data to analyze and provide accurate results, so skipping days or using it at random times can affect the accuracy of your readings.

We recommend using Lumen at least every morning and evening every day to ensure consistent and reliable results.

Invest in Your Eating Habits

It would be best to follow a low-carb diet, practice intermittent fasting , eat at least three hours before the sleep for the last time and other rules that will help you improve your metabolic flexibility. The Lumen app provides customized meal plans and recommendations based on your metabolic data, so incorporating these recommendations into your diet can greatly enhance the device's effectiveness.

Implementing what Lumen suggests you do and doing it consistently is crucial for achieving your goals.

Expand Your Efforts Above Lumen's Device

Macro tracking applications can help you monitor your food intake and progress toward your metabolic goals. Additionally, incorporating regular exercise into your routine can improve your overall metabolic health and enhance the results from Lumen.

Don't rely solely on Lumen to achieve optimal metabolic flexibility. Use it as a tool to guide and inform your eating habits and lifestyle choices, but also make an effort to incorporate other healthy habits into your daily routine.

What Are the Benefits of Lumen Metabolism Tracker? 

The two main benefits of using the Lumen metabolism tracker are its convenience and cost-effectiveness, especially if we compare it with its only traditional analog - metabolic testing in clinical settings.

Easy to Use

Lumen's device is small and portable, making it easy to incorporate into your daily routine. You can track your metabolism from the comfort of your own home without having to make appointments or travel to a clinic.
