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.

| Instead of | Try this | Why it helps |
|---|---|---|
| Lentils (~12g net carbs per 100g cooked) | Cauliflower rice as a base in a curry or stew | Same satisfying bowl, ~3g net carbs |
| Lentil soup | Ground beef and cauliflower soup (spiced the same way) | Protein-rich, thick, warming — ~5g net carbs |
| Lentil salad | Roasted cauliflower + feta + lemon + herbs | Same warm grain-salad feeling, much lower carb |
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 Lentils: 64.0g − 10.0g = 54.0g 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.
