Please add high carb meals there are none available Love the app as it does encourage you to eat well. My only suggestion would be add food ideas for boost days for those of us who have higher carb needs. We paid to have food recommendations but I’ve had a couple days where it just tells me there are no recommendations based on my needs for the meal.

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.

I needed something to jump start my healthy I needed something to jump start my healthy lifestyle. This was exactly what I needed. I lost 15 pounds over 3 months. I followed the lumen recommendations pretty closely for the first month and a half and got good results.

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.
