Wondering how the Lumen device works? Then you’re in the right place!
If you’ve been hearing about the Lumen device and wondering how it can help you hack your metabolism, you’re not alone. This tiny gadget is getting a lot of attention for its ability to measure whether your body is burning carbs or fat—and give you actionable advice to improve your metabolic health. But how the Lumen device works might still be a bit of a mystery. So let’s break it down into simple terms with this quick guide to the Lumen device.
What is the Lumen Device?
Before diving into how the Lumen device works, let’s talk about what it actually is. The Lumen is a sleek, portable gadget designed to measure the carbon dioxide (CO2) levels in your breath. Why does that matter? Because your CO2 levels can tell you if your body is primarily burning carbohydrates, fat, or a combination of both for energy.
This real-time insight into your metabolism is what makes the Lumen device such a game-changer. Instead of guessing how your body is using energy or relying on outdated health advice, Lumen gives you tailored, science-backed recommendations based on your unique needs.
How the Lumen Device Works
Now for the good stuff: how the Lumen device works.
It all starts with a breath.
When you inhale deeply through the device, Lumen measures the concentration of CO2 in your breath. This is possible thanks to a highly sensitive sensor inside the device, paired with sophisticated algorithms that analyze the data.
The key idea here is that the amount of CO2 in your breath correlates with the type of fuel your body is burning. For example:
- High CO2 levels usually mean your body is burning carbohydrates for energy.
- Low CO2 levels suggest that your body is in fat-burning mode.
This simple breath test gives you instant insight into your metabolism, helping you understand how your body responds to food, exercise, and lifestyle habits.
What Happens After the Breath Test?
Understanding how the Lumen device works doesn’t stop at the breath test. The real magic happens when the data from your test syncs with the Lumen app on your phone.
The app takes your CO2 reading and uses it to provide you with a metabolic flexibility score, which ranges from 1 to 5. This score indicates whether your body is burning mostly carbs, mostly fat, or somewhere in between.
But it doesn’t stop there. Based on your results, the app gives you personalized recommendations to help you reach your goals, whether that’s improving energy levels, burning fat, or supporting your workouts.
For example:
- If your reading shows high carb usage, the app might suggest a low-carb meal or a light workout to encourage fat burning.
- If your reading shows fat-burning mode, you might get advice to fuel up with healthy fats and keep your activity moderate.
This level of personalization is one of the main things you need to know about how the Lumen device works!

Why Does the Lumen Device Matter?
To fully appreciate how the Lumen device works, it’s important to understand why it matters. Most of us don’t have a clear idea of how our bodies are using energy. We might feel tired, sluggish, or unmotivated, but we don’t know why.
The Lumen device bridges that gap by showing you exactly what’s happening inside your body in real time. It empowers you to make informed decisions about what to eat, how to exercise, and when to rest—all based on solid data.
For example, instead of following a generic diet or fitness plan, you can adjust your meals and workouts daily to match your metabolism’s current needs. This adaptability is what makes Lumen so unique and effective.
How to Use the Lumen Device
Now that you know how the Lumen device works, you might be wondering how to use it in your daily life. It’s actually pretty simple:
- Start your day with a breath test. This helps you understand your baseline metabolism before eating or drinking anything.
- Take additional readings before and after meals or workouts. This shows you how your body responds to different activities and foods.
- Follow the app’s recommendations. The advice is tailored to your results, making it easy to plan your day around what your body needs most.
Consistency is key. The more you use the Lumen, the more data you’ll collect, and the better the device can help you improve your metabolic health.
