A measure which acts as a high and a low pass filter on a band of less risk which can be monitored by other means, or subject to improvements on measurements and narrow the central zone?

Sounds bloody useful to me.

> your average diabetic who has fairly good control over their blood sugars

I think it's huge for diabetics. It's a mental toll for them. They hate having to constantly prick themselves to take readings. It's awkward, inconvenient and you have to do it multiple times to be sure you got a good reading. And worse of all, it's possible to forget to take a reading when you need to.

I don't understand. All of the diabetics I know personally (one type 1 and two type 2 diabetics) use continuous glucose monitors and have for some time, so they rarely need to prick their fingers anymore. Ketone levels can be checked with a urine test.

There's some difference in the readings of a CGM due to sampling different things (blood with finger sticks vs intercelluar fluid for a CGM) and taking a bunch of vitamin C (pills or in food) can throw the readings off. But I think one or two sticks a day to calibrate the CGM and in situations where readings seem off should be sufficient.

Well I'm a T1D and I'm not generally worried about DKA because I wear a CGM and keep my blood glucose below 140 mg/dL

Which makes me think the market for these is diet-focused folk. Get the FDA to clear it on medical grounds for a specific usecase then sell it more broadly.

This already happens with CGMs. The bulk of the sales is with people who want them for lifestyle monitoring even though they're only medically cleared for diabetes use.

It would be beyond stupid for a healthy "diet focused" person to want to use this. They're not at risk for ketoacidosis, and there is zero evidence that continually measuring ketones would be useful in any sense. That's different from the purported use of CGMs, which is to monitor for glucose spikes in response to specific foods (and even then, the evidence that monitoring glucose spikes in healthy people has any benefits is really thin).

If someone really wanted to measure their ketone levels there are simple urine tests that do it - there is no need to measure it continuously for healthy people. And if they want to see if they're in ketosis it's pretty easy to determine - if they're on an ultra low carb diet and their breath smells like shit, it's a good sign they're in ketosis.
