Net Carb Tracking Demands Verified Data
Net carbs depend on accurate carb AND fibre values. Errors in either compound — subtracting 8g of inaccurate fibre from 18g of inaccurate carbs produces a net-carb number that's wrong twice over.
Verified databases solve this. Nutrola and Cronometer both keep carb and fibre values within 5–8% of references, making net-carb totals trustworthy for keto adherence.
