If you’ve ever heard someone say, “I just have a slow metabolism,” chances are they don’t actually know that for sure. And really, it may not be “slow” per se, but rather—to cop Lumen’s terminology — inflexible.
Created by twin sisters and Ironman triathletes, Merav and Michal Mor, both of whom have PhDs in Physiology (total underachievers, right?), Lumen emanated from the Mors’ desire to help people reach their nutrition, performance, and/or weight loss goals by rejiggering their metabolisms. The premise is that if you know at key moments if you’re burning mostly carbohydrates or fat (or a combo platter of both), you can determine what your body needs to function optimally—aka “personalized nutrition.”
Typically to gauge one’s metabolic rate, an individual must undergo expensive testing in a lab setting. However, Lumen says they bring you an equivalent—or at least scientifically supported(opens in new tab)—at-home option whereby you can measure your own metabolism whenever you want, all thanks to the sleek little breathalyzer you receive when you sign up for the program.
