The ability to not only know what state my metabolism is in, but the fool proof tools to get and stay on track. I have always said I could achieve my health and fitness goals if someone would just tell me what to do because I’m not afraid to work hard.
Lumen not only calculates my macros for me, but tells me how and when to carb cycle, and how to get to fat burning mode. LOVE!
I love everything about Lumen and the app. It has helped me tremendously in focusing my efforts for my health. I lost 10 pounds in the first week and I’m continuing to see changes. It has helped me update my diet. I am exercising more. It’s giving me a window into my own body's needs that I never would’ve had without it.
I have my acupuncturist and my mom ordering their lumens now because they were so excited by the progress that I saw so quickly.
As a lifetime yo-yo dieter….who had reached an all-time high weight, I am so pleased with a plan and tool that allows me to better understand what my body needs, is doing and functions better with. I have lost 14 pounds to date
but most importantly - I am not hungry all day long (as I have been before), have even energy, and am eating more nutritiously than I have (probably) ever. I am excited to continue the program.
Great customer support. A product (tool) that works to meet your goals and really understand the way your body metabolizes food and uses exercise to achieve good health.
I’ve been eating healthy, following my macros and working out regularly (weight training mostly) for a couple of years now. I even went to a nutritionist and went through some evaluations to see what I could do differently. I still felt like I was at a plateau and Lumen appears to be the missing link.
I have learned new foods to incorporate into my clean eating and have learned so much overall about my body and metabolism. I feel better than I already did, my sleep has improved and I’ve lost a few pounds in the first few weeks even though that wasn’t a goal of mine.
I gained pandemic weight and then menopause came. I’ve always been slim but then I was gaining weight with difficulty losing it. Nothing was helping even a pretty good exercise regime. This device arrived one month ago and I’ve already lost 7lbs. It’s kind of like a miracle.
The real time carb/protein/fats tracker really helps me adjust during the day. Gone is the rollercoaster ride of energy and cravings! Amazing, amazing. Thank you!
My friend who is in her 60's has had great success in getting to a healthy weight. I was surprised to learn that she really wasn’t exercising because of a bad leg injury she had sustained, but more surprised to learn that Lumen was how she was managing to lose weight!
I was motivated by her results so I bought one. I’ve been using Lumen faithfully day, and night and have lost 6 lbs in 6 weeks thus far. It took some time to learn how to raise my Flex Score, but I’ve been managing to do it little by little. After all, it’s not a race! Slow and steady for me!
Lumen has been a huge help to me on my journey to metabolic flexibility. I use a continuous glucose monitor at times to keep my blood glucose levels in a healthy range, but at times I tend to rely too much on a very low carbohydrate diet to do so.
By using Lumen too, I can ensure that my low glucose levels won’t be at the expense of metabolic inflexibility.
The staff at Lumen has been extraordinarily helpful — and always promptly — with any issues I had using the Lumen, from app issues to nutrition, to billing and membership.
I'm hitting my weight loss goals and enjoying food again thanks to Lumen. I was skeptical, but the information this device provides combined with the nutrition plan has yielded amazing lasting results.
Lower BMI, higher hemoglobin, lower blood pressure, lower resting heart rate, better body composition, and all the carbs I thought I couldn't enjoy!
I like how Lumen is helping me to learn my body’s signals. I also appreciate that the app tailors my macros throughout the day based on my activity.
I used to meal prep and eat the same thing for a week, but some days my activity and stress levels are different than others, so it makes perfect sense that my body may need fueled differently each day too.
For me this has been a very enlightening experience. Going through all the weight loss and nutrition information that is available on the internet can be very daunting and confusing. But so many of the techniques I had read about before are integrated into the lumen experience.
But without lumen I never could have figured out how to use the techniques. I’m talking about intermittent fasting, carb cycling, tracking my macros, etc. I had done all of these things before with limited gains. But it’s hard to stay on track when you don’t have any feedback as to the changes that are taking place. With lumen you can see what impact your actions are having on your metabolism. This kind of biofeedback is immensely motivating and useful.
Before purchasing lumen, I did as much research as possible and looked at dozens of reviews. I was still surprised when I download the app and began using lumen, as to how much collateral there was.
Not only does Lumen track your metabolism, the tracks of sleep, exercise, and has a built-in food log with a very good barcode, reader and database of foods. It’s very clear that they have done the research on what people want! Worth every penny so I bought two for my wife and I!
