People might get confused by the ‘carb servings’ recommendations at first but in reality, it’s straightforward: one carb serving is 15 grams of carbs. Until the morning measurement is taken, most of the home screen is taken up by the reminder to take this measurement and dietary recommendations are only offered after the morning breath was analysed. The aforementioned Lumen Flex Score is displayed in the Lumen App too.

The portable Lumen device might take measurements but these are all assessed in the Lumen App and dietary recommendations are also communicated here. The Lumen App acts as a command centre for achieving metabolic flexibility. (Image credit: Lumen) Lumen review: the Lumen App

The higher the LFS, the better, and Lumen also explains the score further in the app and in the weekly update email. 0-6 represents low flexibility, 7-14 medium flexibility and 15-21 high flexibility. This represents metabolic flexibility (how efficiently the body switches between macros to fuel itself) and ranges from 0-21.

Taking a measurement right after sleep might skew the reading – apparently, the body burns carbs for a bit after you wake up – plus fasting for longer might help ‘empty out the carb stores’ even more.Īfter the first four weeks, Lumen users are given their ‘Lumen Flex Score’ (LFS). I found the most optimal time to take the morning measurements is just before breakfast, before the overnight fast is broken. The most important time to measure breath is the mornings.

Not only the best way to keep track of macros is to ‘meal prep’ (cook for yourself ahead of time) but people also need to keep track of when they eat these meals. This also means that tracking macro intake is required which can admittedly be a bit challenging to some. Initially, the best (and fastest) results are achieved by taking measurements before and after meals and workouts to help Lumen understand how the body reacts to these. To ‘teach’ Lumen, users have to measure breaths fairly often throughout the day and also track carb consumption. The former is required for more accurate measurements and admittedly, it takes a bit of an effort and dedication to achieve. It takes roughly a week of frequent breath measurements to determine the user’s ‘breath signature’ and four weeks to be given a Lumen Flex Score.
