Carbs in Brown Rice: The Quick Answer
Brown Rice contains 24.9g of net carbs per 100g, calculated by subtracting 1.0g of dietary fiber from 25.9g of total carbohydrates. With 124.0 calories, 2.5g protein, and 1.1g fat per 100g, it is classified as High Carbs for carbohydrate content.
Net carbs — not total carbs — are what matter for keto and low-carb diets. Only net carbs raise blood sugar and affect insulin, which is why tracking them accurately is key to staying in ketosis. Use our Keto Macro Calculator to find your daily net carb limit based on your body and goals.

Best Low-Carb Swaps for Brown Rice
Brown Rice is high in carbs. If you're eating low-carb or keto, these swaps deliver the same satisfaction with a fraction of the net carbs.
| Instead of | Try this | Why it helps |
|---|---|---|
| Brown rice (1 cup cooked, ~40g net carbs) | Cauliflower rice | Even though brown rice has more fiber, cauli rice still wins at 5g net carbs |
| Brown rice in a grain bowl | Quinoa (smaller portion) | Quinoa has more protein — or go full cauliflower rice for fewer carbs |
| Brown rice as a side | Roasted spaghetti squash | Earthy, filling, and about 7g net carbs per cup |
How Net Carbs Are Calculated
Net carbs are calculated by subtracting dietary fiber (and sugar alcohols, if present) from total carbohydrates: Net Carbs = Total Carbs − Fiber. For Brown Rice: 25.9g − 1.0g = 24.9g net carbs per 100g.
Dietary fiber is subtracted because it passes through the digestive system without being absorbed as glucose. It does not raise blood sugar or trigger an insulin response, making it irrelevant for carb counting on keto and low-carb diets.
