But why is it necessary or helpful? It’s one thing to know that you need to balance fat, protein, and carbs, and it’s another to figure out how that looks on a daily basis. It’s a bit heavy on the science, but it’s worth a read if you’re curious about the background of using CO2 as a metabolic measure. The study isn’t specific to Lumen, but it looks at the general health and nutrition guidelines that can be helped from understanding this ratio. We’ll get to the mechanics of using Lumen in a moment, but first, let’s talk about the science behind it. The Lumen app provides you with a snapshot of the macros you want to be hitting in terms of fat, protein, and carbs, based on the reading it gets from your breath. The idea here is that you want to be using carbs before a workout where high-energy food might be helpful, but you want to be burning fat in the morning since that helps with weight loss. Lumen has a device that measures your metabolism via breathing into it it then interfaces with a companion app that lets you know if you’re burning fat, carbs, or a combination of both. You can track what you eat and guess pretty well, but being able to quantify whether you’re burning fat or carbs and how your body responds to workouts can make a huge difference - enter Lumen, which aims to “hack your metabolism” to maximize your health. There are many ways to track your overall health, but most focus heavily on physical markers like heart rate this is helpful, for sure, but that doesn’t always tell you how your body is doing when you’re not actively working out.
