What is Konjac Rice?
Konjac rice, also known as shirataki rice or miracle rice, is a low-carb, low-calorie food made from the root of the konjac plant, which is native to Southeast Asia. The root is processed into a flour rich in glucomannan, a viscous, soluble dietary fiber. This flour is then mixed with water and limewater and formed into rice-shaped grains. Because it is composed primarily of water and fiber, konjac rice is a popular substitute for high-carb rice, pasta, and noodles for individuals following a ketogenic or low-carb diet.
Konjac Rice Nutritional Profile
The nutritional facts for konjac rice are one of its most appealing features for those on a keto diet. The key takeaway is its extremely low net carbohydrate count. While nutritional values can vary slightly between brands, a typical 100-gram serving of konjac rice contains:
- Calories: 10
- Total Carbohydrates: 2–5 grams
- Dietary Fiber: 2–5 grams
- Net Carbohydrates: 0–1 gram
- Protein: 0 grams
- Fat: 0 grams
This nutritional breakdown demonstrates why konjac rice is an ideal food for achieving and maintaining ketosis. The body does not digest glucomannan fiber, so it does not count towards your daily net carb limit.
How to Prepare Konjac Rice for Optimal Results
Many first-time users are put off by the initial preparation of konjac rice, primarily due to its packaging and texture. A successful cooking process is essential for an enjoyable eating experience.
The Preparation Process
- Rinse Thoroughly: Start by draining the konjac rice from its packaging. You may notice a distinct, fishy odor, which is normal. Rinse the rice under cool or warm running water in a fine-mesh sieve for at least one to two minutes until the smell dissipates.
- Dry-Fry: The most important step for improving texture is to dry-fry the konjac rice. Place the rinsed rice in a dry, hot frying pan or skillet over medium-high heat. Stir constantly for about 5-8 minutes to evaporate the excess moisture. This process helps reduce the rubbery or slimy texture, giving it a firmer, more pleasant consistency.
- Combine with Flavorings: Because konjac rice is naturally bland, it readily absorbs the flavors of the sauces, seasonings, and ingredients it is cooked with. After dry-frying, add your preferred fats and seasonings (like butter, coconut aminos, or soy sauce), then toss with vegetables and protein for a delicious dish.
Health Benefits Beyond Keto
While its low-carb profile is the primary draw for keto dieters, konjac rice offers several other health benefits attributed to its glucomannan fiber content.
- Promotes Fullness: Glucomannan can absorb up to 50 times its weight in water, expanding in the stomach to promote a feeling of fullness (satiety). This can help curb overeating and reduce overall calorie intake, which is beneficial for weight management.
- Aids Digestive Health: As a soluble fiber, glucomannan helps keep you regular, preventing constipation by adding bulk to stools. It also functions as a prebiotic, feeding beneficial bacteria in your gut.
- Manages Blood Sugar: The soluble fiber in konjac slows down the absorption of sugar in the intestines, which can help regulate blood sugar levels. This is particularly helpful for individuals with diabetes or those looking to control their glycemic response.
- Lowers Cholesterol: Studies have shown that glucomannan can help reduce total cholesterol and LDL ("bad") cholesterol levels by reducing their absorption in the gut.
Konjac Rice vs. Regular Rice Comparison
| Feature | Konjac Rice (Shirataki) | Regular Rice (White) |
|---|---|---|
| Net Carbs (per 100g) | ~0–1 gram | ~28 grams |
| Calories (per 100g) | ~10 calories | ~130 calories |
| Fiber | Very high (from glucomannan) | Low |
| Satiety | Very high due to soluble fiber | Moderate |
| Texture | Chewy, firm, rubbery (if not dry-fried) | Soft, fluffy |
| Flavor | Neutral, absorbs surrounding flavors | Mild, starchy |
| Primary Use | Low-carb rice substitute | Main staple carbohydrate |
Potential Considerations and Side Effects
While generally safe, konjac rice has some potential drawbacks. The high fiber content can cause digestive issues like bloating, gas, or diarrhea in some individuals, especially if introduced too quickly into the diet. It is always recommended to start with a small amount to see how your body reacts. Adequate water intake is crucial when consuming any glucomannan product to prevent potential choking or digestive blockages, as the fiber swells significantly. Anyone with a history of swallowing difficulties or bowel obstructions should exercise caution and consult a doctor. Additionally, konjac rice may interact with oral medications, slowing down their absorption. It is advisable to take medications at least an hour before or four hours after consuming konjac.

Conclusion
For those on a ketogenic diet, konjac rice is an excellent and safe alternative to traditional high-carb rice. Its near-zero net carbohydrate count, along with the health benefits of its glucomannan fiber, makes it a valuable tool for managing weight, blood sugar, and cholesterol. By properly preparing and seasoning it, you can overcome its unique texture and odor, integrating it seamlessly into a variety of delicious keto meals. Always introduce new fibrous foods gradually to your diet and stay hydrated to enjoy the benefits without discomfort.
