Lumen

 
Lumen, a pocket-sized device designed to “hack” and track your metabolism, officially launches. The device (which resembles a vaporizer) features a hollow interior equipped to read your breath as it passes through. Essentially, it’s founded upon a simple equation: if you’re breathing out high amounts of CO2, you’re burning carbs, and if you’re emitting lower CO2 amounts, you’re burning fat. But the technology designed to capture that equation’s keystone metrics has long been costly and demanding, oftentimes requiring patients to sit for multi-hour breathing exercises (known as RER) and lengthy follow-ups.
