The Lumen device uses a CO2 sensor and flow meter to determine the CO2 concentration in a single breath. This indicates the type of fuel your body is using to produce energy.
Breathe into Lumen
inhale…hold…exhale.

How do you measure metabolism?
Before Lumen
The only way to measure your metabolism was in a hospital or clinic with a costly and time-consuming test known as RQ (a measurement through the blood) or RER (through the breath).
Now
Lumen uses RER as the core data point to bring the same measurement to a home environment by measuring the CO2 in your breath through the sensor and flow meter, based on the RER metric.
Real-time accuracy
In multiple studies, Lumen’s patent-pending technology was deemed to accurately measure metabolic fuel usage when compared to the gold standard RQ for measuring metabolism.
