How Lumen works
The science isn’t new but the technology is.
It starts with a breath
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.

Getting to know you
Lumen is calibrated to your unique CO2 range and lung capacity.
Taking a morning breath
Each morning, Lumen determines the source of your body’s fuel — carbs or fats.
Receiving your plan
Lumen provides personalized nutrition recommendations and daily guidance on sleep, diet, exercise and more.
How do you measure metabolism?
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).
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.
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.
