Welcome to my extensive review of the Lumen device. Before I talk about my review, consider the following resources on the Lumen and related products:

So here's what I found in my 2-week review period:
✅ I won't necessarily use the Lumen in my day to day life but the product can certainly be a value add for many people out there. After years of trying different diets I can pretty much already tell whether I'm in ketosis or not so the Lumen is less useful for me.
✅ In fact, for me, the Lumen is more of a burden because it adds additional complexity to my health routines without helping me in any way.
✅ The Lumen is a metabolism measurement device that tells you whether you're burning mainly carbohydrates or fat or a combination thereof. You measure your metabolism by breathing through the Lumen device
✅ I disliked that sometimes my readings were inconsistent. So once I breathed through the device multiple times Ig to different outcomes on the fat & carbohydrate ratio
✅ I'd also like to see more advanced features. I do consider myself more of an advanced biohacker though. Also, losing weight, the goal behind the app it seems is not a goal that I have or even a problem.
✅ I also disagree about the philosophy that carbohydrate intake the root of all fat loss problems. My clients ate tons of carbohydrates in the past, eventually, and kept losing weight. I don't even believe calories are the problem, and you can read why here: [ Ссылка ]
✅ I also believe the focus on dieting alone for fat loss is fundamentally flawed. Sleep, some exercise, and the environment you live in are of fundamental importance too.
✅ I'm also not getting tons of hard numbers from the Lumen, contrary to what I get with a continuous blood glucose monitoring device and app. I'd like to have more hard data instead of the high-level 1-5 scoring system.
✅ There's also tons of info in the Lumen app that I don't always agree with.
✅ The amount of personal data that's tracked over time in the Lumen is also not that high in quantity. I also question the data that's listed the app because I sometimes fast for 12 hours and are still carb-burning according to the app.
✅ The process of getting many readings in takes a lot of time. Getting many readings is therefore very time-consuming. Also, during a third of my readings, I don't get a good outcome and need to start the process over again.
✅ The fact that getting many readings is time-consuming makes the product less usable long-term - for me at least!
✅ Battery life of the Lumen is great though, so that's a big upside. You can get 15 readings out of one charge
✅ I am a bit concerned about the cleanliness of the product because you're continually blowing into the same device. I'd prefer to have a way to clean the product from the inside.
✅ I've also compared the Lumen to the Levels health app. The latter I've gained a bit more interesting and useful data from, in part, because I've learned a lot about my health.
