I was skeptical at first I was skeptical at first, but this is a true life-changing device that really gives you the control of how to deal with your eating in your health.

Like it I have been able to learn about the personal quirks of my metabolism. I discovered why Intermittent Fasting and CrossFit/Intense Workouts didn't work for me. My body was too stressed by it- so I was not losing weight. I use Lumen to keep myself from going too far... sort of an intense person by nature. 😆

highly recommend I was apprehensive initially because some older users claim the Lumen experience to be time consuming and difficult. I took a leap of faith because I really believed in the science (I'm a medical doctor). My experience has been great. Lumen was so easy to use I did it easily from the first try. It is so quick to use that I do it multiple times a day just to micro manage my stress. It has been so consistent that my readings are almost always the same after repeated measurements, and even when I'm slightly out of breath. Customer service and resources are aplenty, and even I learnt some new things. I am getting it for family and also considering implementing in my practice. Only limiting factor now is the limited food database but I expect to be quite familiar with a rough estimate of my dietary values after a period of logging the macros.

Waste of money This device does absolutely nothing. It is not at all as advertised, does not come with personalized information (the information on the app is very standardized), and the measurements do not provide useful insight into anything that isn't already common sense. Complete waste of money. The company also does not allow returns and does not provide a phone number to speak to anyone regarding dissatisfaction. I believe this company is a scam.

Love using my Lumen daily Love using my Lumen daily. Helps me to know whether my body is burning fat or carbs which lets me plan when to eat my carbs during the day. I’d be lost without it.
