The first device to hack your metabolism

Lumen knows if your body is using fats or carbs for fuel

FEATURED IN

It starts with a breath

Lumen is the world’s first hand-held, portable device to accurately measure metabolism. Once available only to top athletes, in hospitals and clinics, metabolic testing is now available to everyone.

The science isn’t new, but the technology is.

Lumen 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.

Trusted by the Pros

One of the things that I really love about Lumen is that everyday Lumen tells me how to adjust my nutrition plan based on my body’s actual needs.
