Lumen - Metabolic Coach 12+

Good Support

Excellent device which is transforming my attitude to nutrition. Despite my being a qualified nutritionist, Lumen is educating me in a way I had not imagined.

This is not a gimmick or a fad. It is scientifically based and researched. It is designed so that my individual metabolism is monitored. I am not treated as one of the masses, but as an individual with my own unique responses.

My only disappointment is that there are so few suggested meal option and none of those have a preparation method. Most of the breakfast and lunch options use bread as the main carbohydrate. Bread is not a good option for most people. The menu options need to be far more varied and imaginative.

App gives confusing information

I am a vegetarian, and yet the app showed me a video containing a recipe for a meat based meal.
The Lumen and app allows no way to say that you are burning carbs due to high stress (excess cortisone) rather than normal metabolic function, so in my case (night cramps) it underestimates the amount of carbs I need based on my morning reading which is strongly affected by stress due to cramps.
I have used this with a Zoe blood sugar monitor, and when I followed the app recommendations I had a tendency to wake up hypoglycaemic.
The app needs to give much more information about when you need to eat carbs, and, in particular, needs to add any extra carbs due to exercise into the evening meal rather than into “snacks” that one may or may not eat. Much more guidance about how and when to eat carbs is urgently needed.
The device and app give useful information but in my experience you have to be very careful about its carb recommendations. It is probably best to use Lumen in conjunction with a blood sugar monitor so that you can understand what its carb recommendations are actually doing to you rather than just following them blindly. The inability to disambiguate the effects of cortisone from normal carb metabolism is a real concern and something that needs to be addressed urgently.

Useful weight loss tool

I’ve been using my Lumen since February and I’m very happy with it. It did take a while to get the breathing right but once it clicked I’ve not had a problem. There was an issue with an update which meant nothing would load but they released another one the following day which fixed it. I’ve lost 24lbs since starting with the Lumen. I’m not seeking to lose any more weight but the Lumen is still quite keen to limit my carb intake as it’s still training me to make my metabolism more flexible and the only change to my diet has been to limit my carbs as directed though I’m probably under reporting that. Otherwise I’m stuffing my face with lots of calories and I’m only walking, on average, 8.7 miles a day and that’s my only exercise. I had a very nasty chest infection over the winter and the Lumen has helped me on my path to recovery as I have felt good whilst using it and have been happy with how it’s directing me.
