Looked after my son who has T1D for now 5 years, checked keytones maybe 20 times. Compared to blood glucose which we check look at every 5 minutes. Maybe this is more for Type 2 or other diabetes, or for people prone to DKA. Or it is for people with a working pancreas who think looking at their blood sugars (and now keytones) tells them something like soothsayers reading tea leaves

bet marathoners and ultra runners will start using this to improve performance (don't have a problem with that, but it's predictable) too bad it's not "wearable" like a watch but that might be coming eventually too since Garmin has a patent on it * https://the5krunner.com/2026/02/06/garmin-non-invasive-blood... (btw Fenix 9 launched today but it's same hardware as Fenix 8 and no glucose feature)

There has been talk, but as one who hangs around those circles I've not heard of anyone actually doing it. But I'm sure someone is. At the same time, what I'm reading is that CGM won't give a non-diabetic any actionable information.

What about all the other wearable sensors like https://www.stelo.com https://www.hellolingo.com

Those ‘only’ measure glucose levels. As the article says, this is the first approved device that monitors both ketone and glucose levels.

I thought this was going to be a non-invasive sugar-level device, but it looks like in fact the innovation here is that a popular CGM line can now do ketones?

non-invasive continuous blood sugar measurement is mired in patents and technical challenges. Turns out it's really difficult to disambiguate the absorption lines of glucose from other similarly shaped molecules when you're also dealing with untangling skin conductivity, transmissivity, sweat, inflammation etc.

I also think there's no financial incentive from incumbents to develop something like this. Why would abbott develop something that works "forever" if they can milk people buying new sensors every 10~14 days.

I am curious how this will help. During training? During the actual race, the strategy is to eat a much as you can without puking.

> to improve performance

How? Like, what is the mechanism where this is useful?

a regulated blood sugar level aids massively in cellular repair, inflammation reduction, and immune response. These are well studied and established. I could absolutely see a top athlete using AID in the future as part of a recovery routine, but I can also understand reluctance to adopt anything new or weird.

Considering that DKA accounts for 160k hospital admissions a year, your lived experience translates poorly to such a flippant dismissal. [0] https://www.cdc.gov/diabetes/about/diabetic-ketoacidosis.htm...

DKA is what killed the legendary Dan Kaminsky.
