Lumen Reviews metabolism review UK discount code reddit priceLumen gets a peer-reviewed nod

Athletes and those on a diet want to increase the %age burn towards fat as a fuel source. Before Lumen there was no easy or cheap way to measure that.

Lumen estimates metabolic fuel usage ie the degree to which you are burning fats and carbs as fuel sources. However, it does that by only measuring CO2 during rested periods and that is in contrast with the significantly more expensive mechanisms used in laboratories that also measure oxygen levels. Leading us to ask “Does Lumen work?“, In answer to that,  Lumen’s original science showed their product did work and my own experiences suggested that, in a non-scientific way, it seemed to be ‘about right’.

However one of the criticisms levelled at Lumen was that it did not have peer-reviewed science to back up its claims. Fair enough. There is a lot of health and sports tech that has never been peer-reviewed…like some of the optical HRMs on your wrist.

Earlier this month a peer-reviewed study was announced – link to i-jmr.org.

Conclusions: This study shows the validity of Lumen for detecting changes in metabolic fuel utilization in a comparable manner with a laboratory standard metabolic cart, providing the ability for real-time metabolic information for users under any circumstances.

Lumen is in stock and available directly from the manufacturer with a 30-day no quibble guarantee and there are usually discounts to be found. I’ll add in the Amazon link below.

Lumen is often on sale eg now (Jan2020) for $279/£279 (rrp$349/£349…probably Euros are the same discount)

I’ve got an ADDITIONAL code for readers of this site. That code is THE5KRUNNER30 and that will give you an EXTRA $30/£30 off AT ANY TIME. ie both offers work together. This code should work over an above any discounts Lumen offers directly.

You can get a further 10% off if you order two (ie 3 deals together in one)

Note the LUMEN SALE and the 2-for-1 deals should be automatically applied in Lumen checkout. My discount code: THE5KRUNNER30 will need manually adding.

I think your study link is broken. An actual article can be found here. Full PDF is here.

Not to be a nitpicker or anything, but it looks like all we really got is a yet another company-designed and sponsored study at a second tier state school, done on a handful of young and healthy people, and published in a journal that’s stretching a definition of peer-reviewed a bit. In my modest opinion, this may be the same level of scientific rigor as Runner’s World study if beer helps post-run recovery.

It remains to be seen how applicable the study is to both elite athletes and overweight couch potatoes from the real world.

i sent Lumen back after 3 month of use, i think it’s not made for Multisport like Duathlon, it’s a Beta Product, Garmin Integration not work perfect.
If I would follow the dietary suggestions, I would be underweight in a short time, strangely enough, myFitnesspal can do that better
