Lumen - Metabolic Measurement device

[Seven7]

Hey guys, I saw this in an advertisement, Have anybody hear of it, used it? or would it be helpful for ME/CFS?

I always wanted a way to measure if I was over my AT but do not understand the tech on it and see if it would applied to CFS.

Lumen measures the C02 levels in your breath to interpret if your body is using carbs or fats for fuel.

I do not have any affiliations to this company nor have I done full research and know nothing about it. But hoping the people that understand the mechanism give me some feedback if It would be useful to monitor CFS crashes.

I think that's more for measuring if you're in ketosis or not, and helping with fat-loss. Maybe it could tell you at what point during exercise you begin to build lactate a.k.a go over your aerobic threshold. I don't really know how it would help with ME/CFS though.

Well my reasoning is, if you CO2 is high means you passed your AT. Which means you will crash yourself.

So if we can measure what a good CO2 level is, and you can monitor throughout the day, t hen we can avoid damage and crashes by staying under AT. Is not the app for diet per say I am interested in, is the ability / technology to measure CO2 accurately. This is what they measure on those exercise test for CFS (not the VO2 max one) but the one I had done.

@Hip have you seen this?

I am not familiar with the science behind it, but it would be interesting to see if it could be used to monitor energy metabolism, and perhaps detect when ME/CFS patients were nearing their maximum safe exertion level after which PEM becomes a risk.

This device might just be something ME/CFS patients would have to test and calibrate themselves, noting their CO2 levels throughout the day, and throughout any exertion and PEM episodes they have, and observing if there is any correlation.

Yes is what I was thinking, I emailed the company, let me see what they come up with, but just knowing the technology exist, maybe we can tweak for ME/CFS

I'm not so sure it would help ME/CFS patients with crashing. I think this is aimed at nitmsl people and athletes.

After my ME/CFS specialist suggested listening to this podcast when I described the "wall" I hit with increased pace of intensity of any kind of exercise) activity, I sought out metabolic testing.

It was a 50 minute test. First, I was fitted with a heart monitor and then a mask that squashed my face. It had a fat hose hurting out from it, collecting the metabolites I exhaled throughout the test, which was 20 minutes of laying on a table, followed by 30 minutes on a treadmill, measuring the second half of 4 minute increments, walking slowly and steadily at a 1, 2, 4, 6, 8, 10, and 12 degree grade.

It was a difficult test, even walking slower than the technician thought I should be going, but I chose the pace appropriately - I was stumbling but able to complete the test, if I'd gone faster I wouldn't have been able to do it.

My results were unlike any test subjects they've had. I burned carbohydrates at rest, and though I did burn a little far at the lowest levels of exercise, with just a little effort, I burned carbohydrates again.

In answer to your original question, I'm not sure the premise works. I eat about 25-30% of calories from carbs and 50% from fat. The advice the technician and dietician had for me was to eat more carbs, which seems to go against what the Lumen advises - be low carb fir increased metabolic flexibility. They also couldn't explain why I was burning carbohydrates at rest - none of the athletes they tested did that.

And, it seems like the reason I hit a wall with increasing intensity is because I'm using up my glycogen stores too fast by burning carbohydrates when I'm supposed to be burning fat.

My labs seemed to indicate a problem with fatty acid oxidation and I think the metabolic test does too. I'm not sure why but am investigating possible explanations.

I think it might be more complex than the Lumen would show?
