Lumen measures the CO2 concentration in a single breath. The CO2 you exhale is produced when your metabolism turns fuel into energy. Through a patented algorithm Lumen can use the measurement to accurately tell you, at a level comparable to that of gold standard RER measurement equipment, what fuel your body is currently using for energy - fats, carbs, or both.
A more flexible metabolism makes it easier to lose weight, with Lumen you'll train your body to switch more easily from burning carbs to fat. Many users find this helps them with weight loss. Additionally if you select a weight loss track in the Lumen app, Lumen designs your nutrition plan in a way that supports healthy and sustainable weight loss.
Reaching a state of ketosis usually requires extended deprivation from consuming carbohydrates. Lumens methodology isn't about cutting out carbs but rather incorporating healthy carb rich foods into your diet, while training your body to shift more efficiently between using carbs and fats as a fuel source and maintaining a healthy state of fat burn.
