Lumen | Hack Your Metabolism
Unlock your body’s full potential with a single breath. Lumen is the world’s first handheld device to measure your metabolism in real-time, telling you if your body is burning carbs or fats for fuel. This scientifically-validated tool acts as your personal nutrition coach, providing daily, data-driven meal plans and insights to help you manage weight, optimize workouts, and improve your metabolic flexibility.*
The Science of Your Breath: How Lumen Works
Lumen uses a technology called Respiratory Exchange Ratio (RER), the gold standard for metabolic measurement, and makes it accessible anywhere. Your body produces different amounts of carbon dioxide (CO2) depending on whether it’s using carbohydrates or fats for energy. The CO2 sensor and flow meter in your Lumen analyze the concentration of CO2 in your breath to give you a real-time snapshot of your metabolic state.
