The Lumen Breath Device
Before we get into all the details of how it works, here’s what you need to know about what the Lumen breath device actually is. It’s a pocket-sized tool that turns a single breath into personalised guidance.
By analysing the carbon dioxide in your breath it shows whether you’re burning fat or carbs, and then builds you daily nutrition and activity plans around that data.
The result is a clear, easy way to boost metabolic flexibility without complicated tracking or expensive lab work.

So let’s get into our 9 step guide to hacking your metabolism with the Lumen breath device.
Step 1: Get Set Up
First things first, charge your Lumen breath device and pair it with the Lumen app.
It only takes a few minutes and once it’s connected, the app becomes your hub for measurements, daily plans, and meal logging.
Super simple.
Step 2: Learn the Breathing Technique
Inhale through the device, hold your breath for about ten seconds, then exhale steadily until your lungs feel empty.
Don’t worry though, the app talks you through it so you don’t have to count or stress about whether you’re doing it right or not.
Step 3: Take a Morning Measurement
Your first breath of the day is the most important, especially when you’re first getting started using the Lumen breath device.
This reading shows whether your body is burning carbs or fat after a night’s rest and helps the app create your daily nutrition plan.
It’s the most important habit to build because it gives you a clear starting point every morning.
Step 4: Follow Your Daily Plan
From there, the app offers a customised plan with meal suggestions to help you meet your goals. Some days will be lower carb to encourage fat burn, while other days will include more carbs to support activity and recovery.
The best part is that the Lumen breath device updates these recommendations as your metabolism changes, so it’s always customised to you and your body’s needs.
Step 5: Check Around Meals
Want to see how a particular meal affects you? Take a breath before you eat and another an hour or two later.
Comparing these readings shows how your body handled the meal and helps you spot which foods keep you in fat burn or push you toward carb burn.
It’s a really handy way to fine-tune portion sizes and timing.
Step 6: Log Your Meals
Another great way to get to know and understand your metabolism is by logging all your meals. And the app’s food tracker makes doing this quick and painless.
Just snap a photo or search for what you ate and let the app calculate the macros. Over time, you’ll start to see clear patterns between the foods you eat and the breath readings you get.
This is where the Lumen breath device really connects the dots between diet and metabolism.
Step 7: Use It Before and After Workouts
Take a reading before a workout to see if you need extra carbs for energy, and another one after to check how well you’ve recovered.
These quick checks help you understand how exercise affects your metabolism and guide you on when to refuel.
Step 8: Review Your Trends
The app stores all your data so you can look back over days, weeks, and months. You’ll notice when you naturally burn more fat, how sleep affects your results, and which habits lead to better flexibility.
Step 9: Keep It Consistent
A single morning breath plus a few targeted checks is really all it takes to start hacking your metabolism. But you do need to be consistent with it.
The more regularly you use the Lumen breath device, the more accurate and helpful the guidance will be.
Bringing It All Together
Hacking your metabolism with the Lumen breath device really just comes down to consistency and awareness.
Each breath reading shows whether you are burning fat or carbs, helping you match meals, workouts, and sleep to what your body actually needs.
Those small, daily checks build a complete picture of how your metabolism works and give you practical ways to guide it. With just a quick morning measurement and a few extra checks during the day, you can make smarter choices and keep your energy steady.
If you’re ready to take control of your energy and make your metabolism work smarter, the Lumen breath device is the easiest first step.
