Work out diabetic meal carb count instantly with clear inputs, formula shown and shareable results.
Applies the chosen fibre adjustment rule to give net carbohydrate, then converts it into carbohydrate choices and mealtime insulin units.
Carbohydrate counting
Net carbohydrate = total carbohydrate - fibre deduction; one carbohydrate choice is 15 g; insulin units = net carbohydrate / insulin to carbohydrate ratio
Educational estimate only. Not a substitute for professional clinical judgement, and must not be used to make treatment or dosing decisions.
Practices differ; many centres subtract half the fibre only when it exceeds 5 g per serving.
Typically half their carbohydrate is counted, since they are incompletely absorbed.
