Carbs in Quinoa: The Quick Answer
Quinoa contains 17.9g of net carbs per 100g, calculated by subtracting 2.1g of dietary fiber from 20.0g of total carbohydrates. With 107.0 calories, 2.9g protein, and 1.8g fat per 100g, it is classified as Moderate 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.
Is Quinoa Keto Friendly?

Best Low-Carb Swaps for Quinoa
Quinoa 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 |
|---|---|---|
| Quinoa (1 cup cooked, ~34g net carbs) | Cauliflower rice | ~5g net carbs per cup, lighter and works in bowls |
| Quinoa salad | Riced broccoli salad with lemon, herbs, feta | Similar texture to quinoa tabbouleh — ~4g net carbs |
| Quinoa as a grain base | Hemp seeds (3 tbsp) | Higher protein, ~1g net carbs, nutty flavor — no cooking needed |
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 Quinoa: 20.0g − 2.1g = 17.9g 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.
