It's stories like this that make me laf about how the carbophobe and sugarphobe and starchophobe LC catechism will come to a screeching halt. It will end badly for the LC Nomenclatura who don't get honest, quick.
It's only a matter of time.

Thanks for the 4 tbsp experiment suggestion. [...] I tried the 4 tspb idea anyway and put it through a tough test. It passed with flying colors! I consumed 5 tsps of raw fermented honey, which normally would spike my BG to 180-210 mg/d, but this time with 4 tbsp of potato starch, I washed my finger and tested it twice and it measured at only 112 and 120.
