About Lumen

Lumen is a revolutionary metabolic tracker device designed to help people optimize their metabolic flexibility. Metabolic flexibility refers to the body’s ability to efficiently switch between burning carbohydrates and fats for energy. With the help of Lumen, users can measure their daily metabolic levels and make data-based decisions about what foods they should consume to achieve their goals, be it weight loss, fitness improvement or overall health. The Lumen device measures the CO2 concentration in a single exhalation and converts this information into an individual metabolic value. By continuously measuring and analyzing these values, users gain a deeper understanding of their metabolic health and can adjust their lifestyle based on this information.
