Lumen announced the global launch of its wellness device: Lumen. Developed through years of scientific testing and validation, Lumen is the first handheld, portable device and app that measures metabolism in real-time with just breath. Lumen is making personal, at home metabolic tracking available outside of research labs for the first time - revolutionizing the way people approach weight loss, fitness and healthy nutrition decision making. Lumen works by measuring body's carbon dioxide concentration by breathing into a handheld Lumen device. These levels, calculated through Lumen's vast scientific research and development, indicate the type of fuel body is using to produce energy - a mix of fat or carbs. Like having a nutritionist in pocket, Lumen provides with personalized suggestions on when and what to eat to fuel workout, based on metabolism. Lumen supports fat burn and improves metabolic flexibility, which is body's ability to efficiently switch between using carbs and fats as a fuel source. The Lumen device is available at Lumen.me, currently priced at $299 with an MSRP of $349. The device comes equipped with a travel case, charging dock, USB-C Cable, and Premium Customer Support.
