Lumen is the world's first portable device validated to accurately measure your metabolism, by tracking your RER (Respiratory Exchange Ratio). Lumen reveals your body's fuel source and guides you toward optimal metabolic health.
Once available only to top athletes in hospitals and clinics, metabolic testing is now available to everyone.
Lumens CO2 sensor determines the CO2 concentration in a single breath. This indicates the type of fuel your body is using to produce energy and is the key to understanding how your metabolism functions.
Lumen is scientifically proven to meet the gold standard of metabolism measurement (RER) in multiple validation studies.
See how your metabolism is affected by your sleep, physical activity, and nutrition.
Get daily personalized meal plans. Know exactly what to eat and when.
See if you have enough energy before a workout or if you need to fuel up. Breathe afterwards to see the impact on your body.
Lumen tracks your metabolism, sleep, nutrition, and fitness data to provide a Lumen Flex Score, which reflects your success and helps sustain results.
Many of the factors that impact your metabolic health are within your control and can be changed to improve your body’s metabolic flexibility, which is your metabolism’s ability to efficiently switch between using carbs or fats as a source of energy.
Based on this metabolic data, Lumen will provide a daily personalized nutrition plan, as well as other actionable insights on your sleep, workouts, and meal timing. Lumen tracks your sleep, nutrition and exercise in order to provide you with a score that reflects how healthy your metabolism is.
When your metabolism is more flexible, you are better able to burn fat instead of carbs. By focusing on metabolism instead of restrictive or unsustainable diets, Lumen helps you eat the right food for you and improve your metabolic health with daily feedback.
