A great product with great support

“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.

Lumen is a game changer

"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:

It’s kind of like a miracle

"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.

More than expected

"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.

I love love love using Lumen

"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.

It's never too late to start!!

"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!

Understanding my metabolism for the first time in my life

״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.

Lumen Redefined Metabolic Tracking

Before Lumen, understanding your metabolic health meant spending 40 minutes and paying hundreds of dollars for a single detailed, professional-grade metabolic measurement.

 

Lumen's handheld device meets the gold standard. Unlimited measurements can be taken anytime and anywhere.

 

With each breath measurement, Lumen’s advanced algorithm builds a personalized diet plan and lifestyle recommendations based on your real-time results.

FAQs

Metabolic flexibility refers to how efficiently your mitochondria switch from burning carbs or fats for fuel, depending on their availability and your body’s needs.


Being metabolically flexible can be important for disease prevention and helps with managing weight, improved insulin sensitivity, higher energy levels, better sleep, and even longevity.
