๐ก How Net Carbs Are Calculated
Net Carbs = Total Carbs โ Fiber โ (Sugar Alcohols ร 0.5). Fiber passes through your digestive system undigested, so it doesn't raise blood sugar. Sugar alcohols (erythritol, xylitol, maltitol) are partially absorbed โ we count them at 50%.
For keto: stay under 20g net carbs/day (strict) or 50g (liberal). For general low-carb: 50-100g net carbs/day. Net carbs are the carbs that actually impact your blood sugar and insulin.
30g total carbs, 5g fiber, 0g sugar alcohols: Net carbs = 25g. With 8g sugar alcohols: Net carbs = 21g.
