Label the field explicitly. Do not mix total carbohydrate values with “net carb” values in the same unlabeled column.
Decide what the column means
A number labeled only “carbs” may hide different calculations. If you are following a diabetes care plan, ask which measure your team wants you to record. This guide does not recommend a calculation for insulin dosing.
On a US Nutrition Facts label, use the named total-carbohydrate field when that is what your record calls for. Products and labels in other countries can use different conventions; preserve the original label wording.
Keep marketing figures traceable
If a product advertises “net carbs,” write that term beside the number and retain the package information. Do not silently substitute it for total carbohydrate in an older log.
Keeping a separate source column lets you distinguish a label value, a restaurant value, and an estimate. That is often more useful than pretending all entries have the same precision.
Example columns: food; portion; total carbohydrate (g); source; notes. A separate note can preserve a package’s “net carb” claim without adding it to the total-carbohydrate column.
Avoid counting the same ingredient twice
A recipe entry and its individual ingredients should not both be included as if they were separate foods eaten. Decide whether you will log the recipe portion or each ingredient, and use that method consistently.
If you change the recipe, keep the date or version in the name. That makes later comparisons less confusing.
Bring the original context to your care team
For a visit, explain which carbohydrate measure the export contains. A neat total without that explanation can still be misleading.
The free log and Carb Counter & Tracker help keep records. They do not calculate an insulin dose or determine what you should eat.
