Potential game changer for Respiratory Quotient measurement and understanding your metabolism
Lumen is a very interesting device and may be revolutionary for the field of exercise physiology. While measuring respiratory quotient and seeing if you are burning carbs or fats used to require a full face mask to capture exhaled air, lumen does that without all the hassle and discomfort! It is always interesting to see what my body is burning and comparing when I am fasted or fed for insights on what I am fueling myself with.I like that it autosyncs with my health app and I don’t need to enter any metrics manually and also the food that I track feeds in as well. It has a built in personalized nutrition coach that provides insights on what you should be eating macronutrient-wise based on the readings from your daily breaths.Speaking of daily breaths, you’re supposed to do one before bed and one after waking and 10 days later it will give you a better picture of your metabolism. The breathing is a little tricky to get right at first but once you get the hang of it becomes a fun little mini-game. The battery life is great as well; I haven’t had to charge it since initially charging it.

Game changer for understanding my metabolism
I have been using the Lumen Metabolism Tracker for the past week and I honestly love it. The device is sleek, easy to carry in the travel case, and charges quickly with USB C. The app is simple to use and makes it easy to track my breath readings, food, workouts, and sleep all in one place.The most eye opening part is seeing in real time whether I am burning carbs or fat. As someone who lifts and does cardio, it has been motivating to adjust my carb timing, and I have noticed better energy during workouts and steadier recovery. It feels like having a personal coach with me every day.You do need to be consistent with breath tests and logging, but I like the structure because it keeps me accountable and more mindful about what I eat. The subscription is worth it for me because the insights are personalized and have pushed me to make smarter choices with my nutrition.If you are serious about your health and fitness goals, Lumen is an amazing tool. It is not just another gadget. It has helped me truly understand how my body works day to day. Total five stars from me.

Inaccurate results & poor customer service
The results are inaccurate and inconsistent with more reliable RMR testing. I have been trying to cancel my membership but I keep getting stonewalled and prohibited by lumen to cancel.

Helps you keep track
Ive waited till a month before I would give my full review of Lumen and whether or not it helped me. As someone who is going through perimenopause and is starting to see weight gain despite having a very active and fairly healthy lifestyle, I was struggling to see what I needed to change. Testing out Lumen the first week I was struggling to see any fat burning numbers and would continue to experiment with timing my meals, what to eat specifically during the day and night. I started seeing some results and continued playing around my daily lifestyle to see what was the cause of it. I did notice when I was highly stressed it also affected my numbers a lot and tried to focus on lowering my stress/cortisol levels(which can be hard to do). I also experimented the times of when I worked out to play around if that affected anything. I’ve been getting better with my numbers each week stating that I’m in fat burning mode. Trying to also test my carb loading days. What I find fun is experimenting and seeing what the results you’ll get and being consistent. Again, as someone who’s currently in their perimenopause stage it’s good to have Lumen as a progressive track on observing what’s affecting your body from potentially burning fat. It’s a good tool to have instead of just guessing especially when the app has people to help you and a community you can also chat and share your thoughts and struggles.

Expensive
Don’t think the technology is there yet to be accurate enough to trust

Amazing device
Great device and app! Super easy to use, and the insights are spot on. I use it a few times a day to check whether I’m burning fat or carbs, and it’s helped me fine tune my meals and workouts. Totally worth it if you’re serious about health and fitness!
