Net Carbs Calculator

Net carbs are used to estimate the portion of carbohydrate that is most likely to affect blood sugar and ketosis. Instead of counting every gram of carbohydrate equally, the net-carb approach removes fibre and partially adjusts for sugar alcohols.

This is especially useful for people following keto or lower-carb eating patterns, because it allows them to make better choices about foods that contain fibre-rich plant ingredients.

On keto, carb intake usually needs to stay low enough to maintain ketosis. If you only looked at total carbs, many foods like leafy greens, broccoli, cauliflower, seeds, and avocados would seem too high in carbs even though they are commonly used in ketogenic diets.

Tracking net carbs gives a more practical view of how a food fits your daily carb budget.

Not all sugar alcohols behave the same way. Some have a lower impact on blood sugar than regular sugar, but they are not always zero-impact. That is why many calculators count part of them rather than removing them completely.

Erythritol is commonly treated differently because it has a much lower glycaemic effect than other sugar alcohols.
