In a world of sports and fitness tech there is something for everyone out there and the most popular is wearables such as smartwatches and fitness bands and much more but what about something totally unique that can hack your metabolism? Well that is what Lumen does and by the time you are finished testing this out you will know if your lungs are in good shape you will have to use it to understand what I mean but we will touch on that as we go along.

The device itself is small and compact with a rubberised texture to it with a magnetic cap and will easily fit in any pocket or bag if you are going to get full use of this you may need to bring it to work or if you work from home it is fine it is a pretty extensive programme to follow and you would be using it several times a day..

The unit comes with its own dock to charge and one charge will last some time and this again depends on how much you will use it but the battery life is quite good and that is not a bad thing when you think about having another device in the house you need to charge.



Once open you download the app which has great tutorials inside which helps and you are good to go and this is a great test to see how good your lungs are too it is effectively like blowing into a peak flow device where you have to keep the ball between the lines for ten seconds and then you have to repeat this again a second time and you get your results..

You also fill in your personal profile this is very intense and there is many fields to complete to get the full end user benefit from the unit.The goal is to burn more fat and you have a daily chart to remind you on a level of 1-5 all in nice graphics too..


Ok so this is not like a fitness tracker where you read the results and jog on you have to input data daily, several times a day and it will become part of your life so to speak to get the desired results .You get a score out of 5 daily depending on what you eat and this in turn will entice you to change your habits and you can adjust your meals and fitness regime to suit if needed..

For the most you will get a morning score and evening score and recommendations and that is all they are is recommendations and it means you may have to adjust your meals and change your carb intake and so on and the goal is to see what score you get daily and after two weeks of testing you will unlock the lumen flex score.



I have not got mine yet as i missed a day here and there over a few weeks testing and simply forgot to bring with me on my travels and being honest as I mentioned it becomes part of you if your into getting results and that is not a bad thing either but when you think of it it is the same as forgetting your phone if you are into it like I was.

Lumen uses a CO2 sensor and flow meter to determine the CO2 concentration in a single breath. This indicates the type of fuel your body is using to produce energy. Lumen is scientifically proven to meet the gold standard of metabolism measurement (RER) in multiple validation studies.

Receiving your plan

Lumen provides personalized nutrition recommendations and daily guidance on sleep, diet, exercise and more.
Lumen began with twin sisters Merav and Michal – two Ironman winners, and PhDs in physiology. As scientists and athletes, they were passionate about developing a way to provide personalized nutrition, but knew the only way to measure metabolism was costly and time consuming.
So they teamed up with entrepreneurs with  experience building large companies;  Daniel, Dror, and Avi, and after two years of R&D, they developed the first Lumen prototype. Lumen measured metabolism in a single breath, in less than a minute, instead of an hour-long test in a lab!
After four years of hard work and hundreds of beta users, the Lumen team launched on Indiegogo. Lumen broke the $1 million threshold on IndieGogo in weeks, and now Lumen is leading the way in bringing personalized nutrition to the entire world.
Overall for me this is more a motivational product and helps keep you in check and the daily breathing tests might be a bit cumbersome for some people out there depending how often you do it but it can help you get a better mindset and achieve goals and for me it gave me better lung capacity i think..
