If there’s one thing I’ve struggled with over the years, it’s trying to understand metabolism. Honestly, it’s always felt like this vague, mysterious concept that people throw around when diets don’t work or when you’re trying to figure out why your body isn’t responding to workouts. I’ve Googled “how to speed up metabolism” more times than I can count, and nothing ever really clicked—until I got my hands on the Lumen device.
So this is my experience with Lumen, how it’s helped me actually understand metabolism, and why I think it’s worth the investment.
What Is Lumen?
Lumen is this little gadget that fits in the palm of your hand, and it basically acts as a window into your metabolism. You breathe into it, and it measures whether your body is burning carbs or fat for energy. From there, it gives you personalised insights and recommendations to help you make smarter decisions about your meals, workouts, and overall routine.
It’s super easy to use and doesn’t require anything complicated—just a few seconds of breathing into the device and checking the app. The whole point of Lumen is to help you understand metabolism in real-time, rather than guessing or relying on generic advice.
How Lumen Helped Me Understand Metabolism
Before Lumen, I honestly thought metabolism was this fixed thing. Like, if you’re born with a “slow metabolism,” that’s just your life, right? Wrong. What Lumen taught me is that your metabolism is dynamic—it changes based on your activity, what you eat, how you sleep, and even your stress levels. And the coolest part? You can actually influence it.
With Lumen, I started tracking my metabolism every morning. It would tell me if I was in fat-burning mode or carb-burning mode, and based on that, I’d get recommendations for what to eat. For example, if I was burning carbs, the app might suggest a higher-protein breakfast to help shift into fat-burning. If I was already in fat-burning mode, it encouraged me to stick with meals that supported that.
For someone who’s spent years trying to figure out what my body actually needs, this was such a revelation. I finally felt like I wasn’t just throwing spaghetti at the wall and hoping something would stick.
Why Understanding Your Metabolism Is a Game-Changer
Once you start to understand metabolism, everything else starts to make sense. I used to beat myself up over why certain diets worked for my friends but didn’t for me, or why I’d plateau even though I was eating healthily. Now I get that my body needs something different depending on what’s happening internally.
Lumen showed me that there were days when my body was still burning carbs from the night before, so eating another carb-heavy meal in the morning wasn’t helping. It also helped me realise that some of my workouts—especially fasted cardio—weren’t as effective as I thought because my body wasn’t in the right state to burn fat. Having that kind of insight has been a total game-changer for my routine.

The App Makes It Super Simple
I’m not a tech genius, so I was a bit nervous about whether I’d be able to figure out the app, but it’s genuinely so user-friendly. After each reading, Lumen tells you what’s happening with your metabolism and gives you clear, actionable steps. It’s not overwhelming or full of jargon—it’s just practical advice you can actually use to help you understand metabolism and make the best choices for your health.
And for me, the meal recommendations were a huge help too. I’m the kind of person who panics in the grocery store and ends up buying a random mix of things that don’t really work together, but Lumen helped me plan meals based on what my body needed. I also loved being able to track trends over time and see how things like sleep or workouts were impacting my metabolism.
Who Is Lumen For?
Honestly, I think Lumen is for anyone who wants to finally understand metabolism and how it affects their health.

It’s not about quick fixes or fads—it’s about understanding what your body needs and working with it instead of against it.
