- Total carbs are all carbs, including fiber and sugar alcohols.
- Net carbs are total carbs minus fiber and sugar alcohols. Most low carb and keto dieters track these carbs.
- Diabetes net carbs are total carbs minus fiber and half of the sugar alcohols. These may represent a more precise estimate of carbs that affect glucose, and are based on the recommendation of UCSF's Diabetes Teaching Center: https://dtc.ucsf.edu/living-with-diabetes/diet-and-nutrition/understanding-carbohydrates/counting-carbohydrates/learning-to-read-labels/counting-sugar-alcohols/
If you have diabetes, always talk to your doctor before changing your carb counting strategy.
