lumen<\/a> the claims I saw initially were<\/p>\nthat basically find out what fuel your<\/p>\n
body is using right now and it can it’s<\/p>\n
kind of triggering triggering word for<\/p>\n
me but heck your metabolism to know<\/p>\n
whether or not you’re burning carbs or<\/p>\n
fats well I figured pretty early on it<\/p>\n
must be using an R er or respite or E<\/p>\n
exchange ratio R er refers to the amount<\/p>\n
of co2 produced by metabolism versus how<\/p>\n
much oxygen is being used by metabolism<\/p>\n
basically the way you do this is you<\/p>\n
breathe into something and it measures<\/p>\n
like what gases are being expelled from<\/p>\n
your body versus what’s in the room and<\/p>\n
essentially it can tell you based on<\/p>\n
that ratio whether or not you’re<\/p>\n
predominantly burning carbohydrates or<\/p>\n
fats or a mix of both so an re R of 1<\/p>\n
for example means you’re almost<\/p>\n
exclusively burning carbohydrate and re<\/p>\n
are of 0.7 is nearly exclusively fat and<\/p>\n
anything in between there is a mix I did<\/p>\n
see a video and apparently there’s an<\/p>\n
app that goes along with this I don’t<\/p>\n
know if the device has been validated<\/p>\n
but if it’s been validated re R is a<\/p>\n
completely reasonable measure it does<\/p>\n
measure what fuel you’re utilizing now<\/p>\n
before you go out and buy one wait till<\/p>\n
the end of the video because I’m going<\/p>\n
to explain why fuel being utilized is<\/p>\n
not the same thing as fat loss or fat<\/p>\n
gain the app is also giving you<\/p>\n
nutritional and workout instruction<\/p>\n
based on what your AR AR is and some of<\/p>\n
the screens I saw and I don’t know how<\/p>\n
the backend works or anything like that<\/p>\n
so I can only make opinions based off<\/p>\n
what I’ve seen but some of the screens I<\/p>\n
saw were for example you’re doing great<\/p>\n
looks like you’re burning a lot of fat<\/p>\n
have a high carb day today and then<\/p>\n
when hey looks like you’re burning too<\/p>\n
many carbs let’s have a low carb day<\/p>\n
today and that sort of thing which hey<\/p>\n
that seems reasonable but you have to<\/p>\n
understand fuel being oxidized is not<\/p>\n
the same thing as fat loss so for<\/p>\n
example just because you’re burning a<\/p>\n
lot of fat doesn’t mean you’re losing a<\/p>\n
lot of fat fat loss or gain is<\/p>\n
determined by the equation of fat<\/p>\n
balance equals fat stored minus fat<\/p>\n
burned or fat oxidized now if you eating<\/p>\n
really high fat very low carb diet you<\/p>\n
will burn a lot of fat you also store a<\/p>\n
lot of fat because the body doesn’t<\/p>\n
really store carbohydrate as fat there’s<\/p>\n
been several studies on overfeeding<\/p>\n
showing that basically of the fat you<\/p>\n
store approximately 98% of it to 99% of<\/p>\n
it is from dietary fat only one to two<\/p>\n
percent of the fat you store in your fat<\/p>\n
cells is from carbohydrate so carbs<\/p>\n
aren’t really stored as fat it’s mostly<\/p>\n
dietary fat stored as fat so if you eat<\/p>\n
a lot of dietary fat and low<\/p>\n
carbohydrate you’ll burn a lot of<\/p>\n
dietary fat but you’ll also store a lot<\/p>\n
of dietary fat so whether or not you<\/p>\n
lose fat or gain fat will be determined<\/p>\n
by your energy balance not how much fat<\/p>\n
you’re burning now if you’re eating a<\/p>\n
high carb diet for example you won’t<\/p>\n
burn very much fat but you also won’t<\/p>\n
store very much fat<\/p>\n
once again the balance of fat loss or<\/p>\n
fat gain will be determined by your<\/p>\n
energy balance which is how many<\/p>\n
calories are you taking in vs. how many<\/p>\n
you’re expending this device isn’t<\/p>\n
telling you how many calories you’re<\/p>\n
expending it’s just telling you what<\/p>\n
your body’s preferred fuel source is and<\/p>\n
that can also be deceiving in of itself<\/p>\n
for example you cannot change your diet<\/p>\n
at all but if you start doing really<\/p>\n
really high-intensity exercise you’re<\/p>\n
RER will go up you’ll be using much more<\/p>\n
carbohydrate but that doesn’t mean that<\/p>\n
you’re not losing fat it just means that<\/p>\n
that fuel at that particular time is<\/p>\n
predominantly carbohydrate now what<\/p>\n
we’ve seen in exercise studies is that<\/p>\n
if you burn a lot of carbohydrate during<\/p>\n
your workout you end up burning more fat<\/p>\n
throughout the rest of the day if you<\/p>\n
end up burning a lot of fat during your<\/p>\n
workout you burn more<\/p>\n
bow hydrate throughout the rest of the<\/p>\n
day okay your body balance is this very<\/p>\n
well so the problem that I could foresee<\/p>\n
is if this app is using how much fat<\/p>\n
you’re burning is kind of being<\/p>\n
indicative of whether or not you’re<\/p>\n
losing fat and telling you hey you need<\/p>\n
to have a high carb day today because<\/p>\n
you’ve been burning a lot of fat you’re<\/p>\n
doing a great job well if you then have<\/p>\n
a high carb day guess what’s gonna<\/p>\n
happen to your RER it’s gonna go up and<\/p>\n
now it’s gonna tell you you’re burning a<\/p>\n
lot of carbs so guess what’s gonna<\/p>\n
happen the next day it’s gonna tell you<\/p>\n
to have a low carb day and you’re gonna<\/p>\n
oscillate back and forth like that and<\/p>\n
it’s giving no consideration to what<\/p>\n
your energy balance is now I don’t know<\/p>\n
if there’s like a calorie tracker in the<\/p>\n
app or anything like that that could be<\/p>\n
there that could be something but if<\/p>\n
it’s only operating off of RER it’s not<\/p>\n
really giving you useable data in so far<\/p>\n
as body composition now maybe you’re an<\/p>\n
athlete I would argue then that there’s<\/p>\n
still limited data than it provides but<\/p>\n
maybe you just really care about what<\/p>\n
your fuel selection is I personally<\/p>\n
don’t because again at the end of the<\/p>\n
day it’s gonna boil down to energy<\/p>\n
balance and how many calories you’re<\/p>\n
consuming versus your energy expenditure<\/p>\n
based on your BMR and meet TEF and your<\/p>\n
exercise energy expenditure so I think<\/p>\n
the tool itself may be reliable I think<\/p>\n
making determinations on your diet based<\/p>\n
on the fuel that your body is using at<\/p>\n
the time it’s probably very unreliable<\/p>\n
in terms of trying to get yourself<\/p>\n
consistent results that’s my take on it<\/p>\n
personally I’m not gonna buy it and I’m<\/p>\n
not gonna recommend my clients buy it<\/p>\n
and I don’t really know what data that’s<\/p>\n
really helpful for body composition it’s<\/p>\n
going to provide but if you really care<\/p>\n
about whether or not you’re burning<\/p>\n
carbohydrate or oxidizing fat in<\/p>\n
regardless of whether or not you’re<\/p>\n
gaining or losing fat then maybe it’s<\/p>\n
helpful alright guys hope you enjoyed<\/p>\n
