Understand. Record. Prepare.
Record carbohydrate amounts and how they were measured.

On a US Nutrition Facts label, total carbohydrate includes dietary fiber, total sugars, and other carbohydrates. A product may also advertise a separate net-carbohydrate figure. Preserve the original wording, especially across countries or products; your care team can explain which measure fits your needs.
A carbohydrate record needs a consistent definition as well as a portion. A label's total carbohydrate, a product's advertised net-carbohydrate figure, and the weight of the food are not interchangeable numbers. This hub's log and calculator are labeled for total carbohydrate.
Use the guide to understand record choices, scale the label to your portion, and keep the original source visible. If you also record glucose, retain its separate units and timing. The companion app provides food records and reports. The website does not derive an insulin dose or decide which carbohydrate method your care plan should use.

What sugar-free tells you about a carbohydrate label
Check the total carbohydrate row, serving basis and ingredients when a package says sugar-free. The front claim does not describe the whole food.
Why carbohydrate labels differ between countries
Avoid mixing US and European carbohydrate-label conventions when copying imported foods into a record or comparing app entries.
Keep total and “net” carbohydrate separate in your log
A record is easier to use when it says which carbohydrate figure you entered and where it came from.

Use a US Nutrition Facts label for this tool: total carbohydrate includes dietary fibre and total sugars. Other countries use different label conventions. Enter those parts separately and they stay separate in the result.

Do not add fibre and sugars to total carbohydrate, or use this to calculate insulin. No “net carb” value or treatment advice is generated.

Total carbohydrate portion calculator
Scale the label amount to the portion you ate. Both portion quantities must use the same unit and preparation basis. The result is record arithmetic, not an intake target.
Total carbohydrate amount = label amount × portion eaten ÷ label portion.
Check the label wording and units before using the result. Estimates remain estimates.
Carb Counter & Tracker
Keep carbohydrate food records and nutrition summaries.
