Lumen is backed by science

The idea of measuring metabolism through the breath isn’t new, but our technology is. The Lumen device determines the CO2 concentration in your breath, which indicates the type of fuel your body is using to produce energy– fat or carbs.

Your metabolism is unique

It is affected by an array of factors: genetics, age, weight, gender, hormones, body composition, exercise, diet, eating habits, psychological state, environmental factors, sleep, and more.
Learn more about metabolism

What Lumen has done is taken this very complex technology and miniaturized it into a device that you can breathe into and get immediate feedback about what kind of fuel your body is metabolizing.
