A small, portable, handheld breath analyzer device paired with a subscription based app.
It measures your body's metabolic state—specifically, whether you are primarily burning fats or carbohydrates for energy.
You breathe into the device (inhale, hold for 10 seconds, exhale). It uses a sensor to measure the concentration of carbon dioxide in your breath. This is based on the scientific concept of indirect calorimetry.
The entire Lumen program hinges on the concept of Metabolic Flexibility. A person with high metabolic flexibility can easily switch between burning fat (e.g., while fasting or resting) and burning carbs (e.g., after a meal or during intense exercise).
Lumen aims to guide your daily choices to improve this flexibility, often through strategic timing and moderation of carbohydrate intake.
