Miracle noodles are one of those items that are pretty much allowed anywhere anytime.
They are made from the Konjac root, called glucomannan fiber. They are purely soluble fiber, which your body can’t digest, so it goes through you – which is why they are calorie free to you.
I have a detailed guide on Miracle Noodles for you – they are fine on P2 too! I had them daily for a few of my rounds.
