The option to use Net Carbs instead of Carbs isn’t available in all settings or regions within the Lifesum app. Here’s how the option to track and view Net Carbs is enabled.
Requirements to Enable Net Carbs Tracking:
To see the option to track Net Carbs, you need to:
- Select a Keto Program or Keto Meal Plan in Lifesum.
- Set the app language to English.
Only under these conditions will the Net Carbs option become available.
Why Net Carbs Isn’t Available in All Regions:
The calculation of Net Carbs is primarily relevant to users in the U.S. because of differences in how carbohydrates are displayed on nutrition labels:
- U.S. Nutritional Labels: Carbohydrates on U.S. labels include fiber, so the formula to calculate Net Carbs is: Total Carbs – Fiber = Net Carbs
European Nutritional Labels: Fiber is already subtracted from the carbohydrate total on European labels. This means that in Europe, Total Carbs = Net Carbs.
As a result, the Net Carbs feature is not shown for European users, as it would not provide any additional value in these regions.
