7 Common Net Carb Mistakes (and Easy Fixes)

1. Ignoring serving size. One package can be two or three servings—check the label.
2. Forgetting fiber. Subtract all listed dietary fiber from total carbs.
3. Over-subtracting sugar alcohols. Erythritol is often subtracted fully; others (especially maltitol) may have more impact.
4. Not rounding consistently. Pick a rule (e.g., one decimal place) and stick with it.
5. Comparing products by total carbs only. Two items with the same total carbs can have very different net carbs.
6. Skipping vegetables. High-fiber veggies keep net carbs modest and meals satisfying.
7. Doing math on the fly. Use the calculator or embed the widget to save time.
