I'm a longtime fitness coach and can say with absolute certainty that THIS THING WORKS!!!!

It gives me great insights and helps me know how and when to fuel my training efforts.

Do you guys have any more test Results that you can share? Like before and after stories or five months with lumen? Also how do you clean the unit?

On Keto now, lost 30 pounds in 5 weeks. Once I get to my target of losing 65 pounds I'm gonna start using the Lumen and mix it up 😁🤩😝

First day today & already an eye opener. What hormone drs say we can eat is not what everyone can eat

Coach greg can see this from far away....

Can we get a thunderf00t check on this one?

I wonder if the next product will be a scanner that will tell you the nutritional value of foods.

I wasn't a believer at first but I am now. I didn't get it but once I started to understand the science, I love how it helps me hack my metabolism.

Biochemistry question: How does Lumen tell whether it's carbs or fats being burned from your breathe if both are expelled from the body in the form of CO2?

CO2 from fats and CO2 from carbs (glucose/pyruvate) are exhaled all the same and have no chemical difference. I'm wondering from a biochemical/metabolic perspective how the device differentiates and analyzes in real time like that.

Thanks!

how can a med student be so bewildered? give an honest testimony and just say it's great that this technology is now available so conveniently for all of us to use. Someone who is about to enter med school should already have an idea about ketosis

How do you quantify nutrition with a breath?

[PedalBikerUK]

I might be old fashioned but a fingerprick and then well authenticated blood glucose and blood ketone measurements are still going to remain my go to tests. If my blood glucose is normal and I've elevated my blood ketone level as far as I'm concerned I'm doing Ok and I'm using fat from one source or another as a significant energy source. Ok, so I have to buy some test strips from time to time but it's a whole lot less expensive and better verified than the subscription model offered here.

Did they really have to make the shape similar to a vape?

There are so many questions under this video, yet no one from their Social Media team has answered since it was posted in Sept. 2019. Not good at all.

[jolongenbaugh]

Don’t know how to charge it. Where on the device does the charging line plug in?

[ericsimmons]

Why do so many people avoid making eye contact with this young lady? She gives them parfaits.

If you ever lose the device and try to activate a new device through their app using your old account login, good luck. I am so god damned frustrated. I received an "activation code" via email that I cannot use because the dialogue page to enter the code doesn't appear when I login to the app. It seems to revert back to the former device for some reason. My Bluetooth settings shows the lumen device in the list of available but when I go to pair in the Lumen app it messages me and says, Sorry, you can only use your personal device"...which I'm guessing means that if I'm not using my old device, it will not allow a second device to pair. How do I delete the other device? Well, that's a mystery because I've tried everything and nothing works.

Does Lumen work for an UNDER ACTIVE THYROID?

My lumen says it’s waking up. Not helpful yet. Help!
