22 consecutive days of fasting data – all three checked shortly after getting up each morning before eating or drinking anything.
I used Precision Ultra to read blood ketones (BHB). I also used the cheap $12 Greenwon BAC meter as well as the Ketonix 2015 breath meter.
$12 Greenwon BAC Meter
[When testing with this meter, I do it three times and take the highest reading. I exhale half way, then put mouth on device and blow out as fast as I can, attempting to get tail end of breath into meter, all within 5 seconds – if I go over 5 seconds, the meter gives me a goose egg and I have to scratch that test and start over. BAC results in chart are in mg/100ml. To convert to BAC% divide by 1000. E.g. 47 mg/100ml = 0.047]
