How to Use Lumen
What Is Lumen?
Lumen works by analyzing the carbon dioxide (CO₂) concentration in your breath through a small, portable device. This reading reveals whether your body is burning carbohydrates or fats for energy at that moment. With that data, the companion app creates daily nutrition plans, macronutrient targets, and lifestyle recommendations to help you reach your health goals. The insights go far beyond what traditional fitness apps can offer.
Lumen is also one of the many innovative wellness technologies featured on I Need AI, a platform that highlights real-world AI solutions for health, productivity, and more.
How to Get Started with Lumen
To begin using Lumen, order the device from www.lumen.me and download the Lumen app on your mobile phone. Once your device arrives, charge it using the included dock and pair it with the app via Bluetooth. The app will walk you through a calibration process where you’ll take a few breaths to allow the system to understand your baseline metabolic patterns.
Once calibrated, Lumen is ready for daily use. The best time to take a reading is in the morning after waking up and before eating, as this gives the most accurate insight into your fasting metabolic state.
How to Take a Measurement
Using Lumen is simple. Open the app and tap “Measure.” You’ll be asked to inhale deeply through the device, hold your breath for a few seconds, and exhale slowly back into the mouthpiece. The device then processes the carbon dioxide level and classifies your metabolic state on a scale from 1 (burning fat) to 5 (burning carbs).
The app will display your result along with a tailored suggestion — such as “low-carb day” or “balanced day” — to guide your food choices and activity levels.
Using Daily Insights
Lumen uses AI and historical data to offer daily plans. These include:
-
Meal recommendations with macro breakdowns
-
Carb and fat targets based on your metabolism
-
Fasting and meal timing guidance
-
Exercise tips to match your fuel state
Over time, the app learns how your body responds to different foods, workouts, and lifestyle choices. You’ll begin to see patterns, such as how late-night meals or poor sleep affect your fat-burning ability the next day.
Integration with Lifestyle Goals
Whether your aim is to lose weight, improve metabolic flexibility, or enhance athletic performance, Lumen allows you to track your progress using weekly reports and a detailed insights dashboard. The more consistently you measure, the more accurate and helpful the recommendations become.
You can also log workouts, sleep, mood, and food manually or sync with devices like Apple Health for a broader view of your lifestyle habits.
Who Should Use Lumen?
Lumen is especially valuable for people who want to go beyond calorie counting and understand how their body works on a deeper level. It’s suited for individuals interested in:
-
Weight loss through carb cycling
-
Improving energy and focus
-
Optimizing workout performance
-
Balancing fasting and nutrition
-
Building metabolic flexibility
It’s also helpful for people managing insulin sensitivity or adjusting to ketogenic or low-carb diets.
Benefits Over Traditional Tracking
Traditional health apps estimate results based on activity and food input. Lumen gives you real metabolic feedback based on how your body is actually operating. This helps you make smarter nutrition decisions that are in sync with your current energy state — not just your goals.
