Konjac noodles · 5 calories · 1g net carb
Shirataki noodles
Shirataki noodles are noodles made from konjac, a root vegetable eaten in Japan for centuries, and they are almost entirely soluble fiber and water. That’s the reason a serving of our konjac noodles has 5 calories and 1g net carb: your body doesn’t break that fiber down for fuel the way it breaks down a grain.

Any six packs · one boxThe short version
Shirataki and konjac noodles are the same food. Shirataki is simply the Japanese name for the noodle, and konjac is the plant it comes from. The fiber inside is called glucomannan, and here’s the simple split: there are two kinds of fiber. Insoluble fiber is kind of rough and moves things through. Soluble fiber is more like a gel. It holds water, so a bowl built on it sits with you longer, and it’s food for the natural bacteria in your gut.
I first tried these at a small vegetarian restaurant outside Kyoto in 2006. They come fully cooked and ready to eat. Rinse them under cold water for about 90 seconds, dry-pan them briefly for a firmer bite, then let them simmer in your sauce or broth. All three noodle shapes, and our shirataki rice, share one short label: konjac flour, water and a little citric acid.

What are shirataki noodles?
Shirataki noodles are noodles made from the konjac plant, a root vegetable that has been a staple in Japan for centuries. They’re almost entirely water and a soluble fiber called glucomannan, which is what holds the noodle together. Ours are konjac flour, water and a little citric acid, and nothing else.
How many calories are in shirataki noodles?
Our konjac noodles have 5 calories a serving, and a 7 oz bag holds about 2 servings. That’s why people search for them as zero-calorie noodles. They aren’t quite zero, but they’re close, because calories come from starch, sugar, protein and fat, and konjac is essentially fiber and water.
Are konjac noodles keto?
Yes. Each serving has 1g net carb and 2g of fiber, with no flour, grain or sugar, so they’re keto-friendly by nature. They’re also gluten-free and Low FODMAP certified. If you want noodles with as few carbs as an honest label allows, this is it: 1g net carb, right on the bag.
Are shirataki noodles and konjac noodles the same thing?
Yes. Konjac is the plant, and shirataki is the Japanese name for the noodles made from it. You’ll also see them called konjac pasta or miracle noodles. Same fiber, same short label.
Do you have to cook shirataki noodles?
No. They come fully cooked and are ready to eat straight from the pouch. Most people warm them: rinse under cold water for about 90 seconds, dry-pan them briefly to drive off extra water, then add your sauce or broth and let everything cook together. The longer they simmer in a sauce, the more flavor they take on.
