⚖️ Final Say
Read the summaries of what reviewers think about Lumen below.
“We think this device can help you reach your goals and stay on a healthy diet and lifestyle regime. If you’re looking for something to help you be more conscious of what you’re eating, Lumen is definitely something you want to check out to hack your metabolism.”
“Lumen is a fitness device developed by Metaflow LTD. This device is a metabolic measuring device that can accurately give you results just by using your breath. You simply breathe on the device and it will give you stats for your metabolism and how you can adjust. These accurate readings can help you alter your diet and lifestyle based on how you want it to be.”
“After getting to test out Lumen and also talk with its founders Merav and Michal, I’m convinced they’ve built a device and company that’s going to change lots of lives for the better.”
“If you’re like me and have no idea what most of the health and fitness realm even means, you might benefit from a product like Lumen, but at $350 it’s definitely a luxury and not something I’d typically spend my money on. On the other hand, if you have considered hiring a nutritionist, this would be a less expensive step to take. For those of you in the middle, well … you can return it within 14 days if it doesn’t help you eat better.”
“This device will help you pay more attention to and learn about your body. However, some of its scientific claims may be overblown.”
“Lumen is a fascinating new device that offers a unique way to measurably improve one’s metabolism and metabolic flexibility. It’s also a great alternative to measuring ketone levels in your blood, urine or breath. I strongly believe that the sophistication of the device, combined with its unique and futuristic look, increases the chances of its effectiveness — because you want to keep using it and show it off to your friends and family.”
“By the end of my week using Lumen, I felt better — both physically and mentally. Using my personalized meal plan, I gained enough energy to exercise, which in turn improved my mental health.”
“At $350, Lumen isn’t cheap. However, as far as wellness and fitness gadgets go, it’s not outrageously priced given its feature set and how much nutritionist visits, fitness apps, and personal trainers cost over time. On the plus side, there’s also no subscription fee. That said, it’s a bit steep for casual use. You’ll probably get the most value out of it if you’re someone who is already serious about food-logging and well-read on the subject of fitness nutrition.”
“If you decide to try Lumen, keep in mind the technology’s limitations and use it more as a suggestion than factual advice. Most people can benefit from taking a closer look at their diets, though, so there’s a good chance that using Lumen will lead to positive results for your health.”
