Shirataki Noodles

AKA konjac noodles, glucomannan noodles, konnyaku noodles, Japanese yam noodles

Konjac noodles also called
shiritaki noodles

Shirataki or konjac noodles are naturally low carb, low glycemic, and zero calories.  I don’t know about you, but I’m skeptical when I hear stuff like that. How can a food, especially pasta, have zero calories and zero net carbs? I mean, seriously. Tell me. How?
