The zero-calorie “Miracle Carbs” for keto diet. Konjac also known as Shirataki is a unique food grows in Japan, China and Southeast Asia. It contains very few digestible carbs — but most of its carbs come from glucomannan fiber, that comes from the root of the konjac plant.
Lime water helps glucomannan hold their shape, so it’s boiled and then shaped into noodles or rice-like pieces.
