Zero-carb rice is not actual rice; it is a rice-shaped substitute made primarily from konjac fiber, water, and sometimes other plant-based ingredients, offering almost no carbs or calories.
If you are cutting carbs or managing blood sugar and miss the texture of rice in stir-fries or bowls, you have likely come across something labeled “zero-carb rice.” The name is misleading — real rice always contains carbohydrates. What the label actually refers to is a family of low-carb rice alternatives made from the konjac plant root and other high-fiber ingredients. These products work well for keto, low-carb, and diabetic-friendly diets, but they are a different food entirely, with a different nutrition profile and preparation method.
What Is Zero-Carb Rice Actually Made Of?
Almost all zero-carb rice products are based on konjac, a root vegetable native to Asia. The root is processed into glucomannan fiber, then shaped into rice-sized grains. Some brands add rice flour, seaweed extract, or psyllium husk for texture. Because konjac fiber is nearly indigestible, it contributes negligible digestible carbohydrates and calories.
Common product names include shirataki rice, konjac rice, and branded versions like Zero Slim, Diva Rice, and Myprotein Zero Rice. The key point is that none of these are grains — they are a water-and-fiber gel pressed into a rice shape.
Zero-Carb Rice Nutrition: What the Numbers Actually Say
Nutrition varies by brand, but the numbers are consistently far below real rice. A standard 100 g serving of cooked white rice contains around 28 g of carbs and 130 calories. By contrast, a typical shirataki konjac rice provides about 0 g net carbs and 10 calories per 100 g. One source that reviews rice substitutes notes that products range from 0 g net carbs to roughly 6 g of carbs per 100 g depending on formulation.
The takeaway is that labels vary, so checking the specific product’s nutrition panel before assuming “zero” is essential.

How To Use Zero-Carb Rice (And Not Ruin It)
The biggest mistake people make is treating it like regular rice straight out of the package. Konjac-based rice comes packed in liquid and can have a faint odor and slippery texture if not prepared correctly. The fix is simple: rinse the rice thoroughly in a fine-mesh strainer under cold running water for 30 seconds, then drain well. This removes the packing liquid and most of the smell.
After rinsing, add the rice directly to a hot stir-fry, soup, or sauce and cook for 2–3 minutes until heated through. Unlike real rice, it will not absorb liquid or become fluffy — it stays tender and separate. It works best in savory dishes where it can pick up the flavor of the sauce or seasoning. For a quick fried rice, break up clumps with a spatula while stir-frying, then finish with soy sauce or tamari.
A less common homemade option is “egg white rice,” which involves baking blended egg whites and gelatin into a rice-like texture, but this is a DIY recipe, not the commercial product most people are searching for.
Common Mistakes And What To Watch For
First, do not assume every “zero-carb rice” product is pure konjac. Some blends include rice flour, which adds real carbs and may exclude strict keto or gluten-free diets. Always check the ingredient list — if rice flour appears, the carb count will be higher.
Second, understand that these products are not nutritionally equivalent to rice. They are overwhelmingly fiber and water, with virtually no protein, fat, or micronutrients. They are a useful tool for cutting carbs or calories, but they should not be the only source of calories in a meal. Pair them with a protein source and vegetables.
The actual numbers are low enough for most low-carb and keto plans to treat them as zero, but the legal and nutritional reality is “very low” — which is all most dieters need.
FAQs
Does zero-carb rice taste like real rice?
No. It has a neutral, slightly chewy texture and takes on the flavor of whatever sauce or seasoning it is cooked in. It does not taste like a grain, but many people find it acceptable in stir-fries and bowls.
Is zero-carb rice safe for keto and diabetic diets?
Yes. Pure konjac rice contains negligible digestible carbs and has minimal impact on blood sugar. However, blended products with rice flour may add enough carbs to matter for strict keto — always read the label.
Where can I buy zero-carb rice?
It is available online through major retailers and supplement stores, and in some Asian grocery stores or health food shops under names like shirataki rice or konjac rice. The product selection and pricing vary, so the product roundup page can help you compare the best-selling options quickly.
