I know you've had lean on.

I've used that.

And there's other apps out there.

Yeah.

So the macronutrient ratios in the composition, but also the total amount of calories, which

At the time when I got into this, everybody said, you know, if you do ketogenic diet, you don't have to track calories.

Calories don't matter.

I just knew that was BS to begin with because there are some people who can easily overeat on a ketogenic diet.

I could sit down with a bag of macadamia nuts and polish the bag off or sour cream or heavy cream or whatever.

So it's easy to do.

So yeah, track total calories, macronutrients, track your blood ketone levels.

You could do urine or breath too.

With the breath meter, I do think that's pretty legitimate because breath acetone correlates with seizure control.

There was the Biosense device, but they've kind of fallen out of favor.

There's a device called KetoAir that's pretty good.

It's like the size of a pen.

And that actually correlates really well with some of the blood ketone measurements.

I do notice that if I'm in a calorie deficit, my blood ketones can be very low, but my breath ketones are high.

And I think your ketone production that you're measuring

is a consequence of ketone production and ketone utilization.
