Davis’ Health Sports Medicine program - aren't entirely convinced of its accuracy, or usefulness. However, the experts Mashable consulted - two members of U.C. Lumen’s internal studies and a study conducted by San Francisco State University (Opens in a new tab) have found that Lumen’s measurements are “comparable” to an RER measurement taken by a traditional device. This ratio reveals what kind of fuel a person is running on lower ratio means fat, higher means carbs. When you go in for a metabolism assessment, one number you'll get back is your Respiratory Exchange Ratio (RER), which is the amount of CO2 expelled divided by the amount of oxygen inhaled. Surprisingly, the amount of oxygen you breathe in, and CO2 you exhale, can contain a lot of information about how you process food. Measuring a person’s metabolism usually takes place in a lab, and is not typically something people do regularly - let alone daily. To actually understand Lumen, you need to know a bit about metabolism science, so bear with us for a sec. It distributed its first orders to backers earlier this year, and begins shipping out orders of the product, which you can buy for $299 on Lumen's website (Opens in a new tab) (that includes the device and app), Tuesday. Since then, the company has raised over $17 million in venture capital, according to Crunchbase (Opens in a new tab), and has received press and praise (Opens in a new tab) for the innovation of bringing a test that’s usually done in a lab environment to a compact consumer device. Lumen ran an explosive IndieGoGo campaign in 2018, raising over $2.3 million with nearly 10,000 backers. Michal Mor and her twin sister Merav Mor are both Israeli physiology PhDs and triathletes who co-founded Lumen in 2016. The Lumen breathalyzer and app Credit: lumen how my body's functioning, how the things that I did in the past few days affected me, and what should I do today, what should I eat in order to achieve my goals?” Michal Mor, one of Lumen’s co-founders, told Mashable.
“Lumen comes to answer some very basic questions users have. It follows with a recommended meal plan of approximately how many carb, fat, and protein servings you should be eating, with the ultimate goal of making your metabolism more efficient. Each time you breathe into it, the device analyzes your breath, giving you a score on a scale of 1 to 5 to tell you whether your body is running on energy from your fat stores (the ideal "fat burning" 1 or 2 state), the carbohydrates you’ve consumed (a 4 or 5), or a combination of both (a 3).
Through the device and app, Lumen aims to give people more information about how they process food in order to achieve fitness and weight loss goals by "hacking" their metabolism. Lumen is a new health product that officially launches Tuesday. Yes, it's confirmed: I overdid it on the tacos and wings last night. I sleepily inhale through it, hold my breath for 10 seconds, then exhale back through the device and wait for the results to come in on the Lumen app. and a small breathalyzer-like device called a Lumen - which looks sort of like a bulbous silicone vape - is about to tell me what I already know.
