What would be the top three or four mistakes that people are making?

So tracking because you want people to be able to correlate the blood levels they're seeing with what they're eating.

What is the state of the art on urine and breath meters these days?

Yeah.

Also under high exercise, normal exercise, super normal exercise, fasting, et cetera.

Yeah.

Yeah.

And then urine.

People still use it.

My view back at the time was I was never going to get better precision than using blood.

So it's a device, is it microneedles or is it a long filament?

Does anybody have one of those commercially ready yet?

So if mistake number one is you're not measuring your actual ketone levels and you're not tracking what you're eating so you can see the association of, hey, when I ate this, it went down.

When I ate this, it went up.

What are some other mistakes people make with their diet formulation?

Is that they typically err on the side of too much protein, not enough protein?

Are they not realizing where carbs are sneaking into their diet?

And what kind of guidance do you give people?

How many grams of carbs a day do you tell somebody or do you vary that based on their activity level?

But if someone just says, look, I just want to do this on my own, just like any other diet I might follow, what would be sort of the guidance you'd give them?
