In normal healthy individuals, BrAce can range from 0.5 to 2.0 ppm. Adults on ketogenic diets (e.g., high fat with low carbohydrate) can have elevated levels of up to ∼40 ppm.
The article includes a graph which has the same data:
This actually correlates to what I measured with my Ketonix. I got numbers from 4 (in Ketosis) to 22 (when fasted 10 days).
That correlates to the scale above which shows a Ketogenic Diet in an adult to go from 2 to about 40.
The problem is that the middle of this Ketogenic Diet scale is 10. It took me several days of fasting to get to this level. So for normal Ketogenic dieting there’s not enough scale to blink the colored LEDs on the unit. If you look at the fasting scale you can see I never reached the higher levels I should have been seeing at 10 days into a fast.
Seems like the unit sort of works and sort of doesn’t work. If it is accurate for PPM then I would never see a number above 50% if I was at the very top of the Ketogenic diet scale – which is not realistic.
