Net Carbs
Updated March 27, 2026
Net Carbs lets Fuel subtract fiber from your carb budget display, so you can follow a lower-carb approach and keep the rest of your day easy to read.
What Net Carbs changes
When Net Carbs is turned on, Fuel subtracts fiber from your carb budget display. This changes how carb progress is shown in the parts of the app that guide your day.
Your logged food data stays unchanged.
Where to turn it on
You can turn Net Carbs on in App Preferences.
- Tap You tab
- Open App Preferences (Gear Icon)
- Turn on Net Carbs
The setting description in Fuel says Subtract fiber from carb budget.
What to expect after you turn it on
Fuel starts showing Net Carbs in the places where carb budgets guide decisions through the day. On Today, carb labels change from carbohydrates to Net Carbs. You may also see Net Carbs in widgets, watch views, shortcuts, and coaching where Fuel talks about the carbs you have left.
This makes it easier to stay consistent if you count digestible carbs rather than total carbs.
When Net Carbs is useful
Net Carbs is a good fit if fiber-heavy foods make your carb budget look tighter than it feels in real life. If you already think in Net Carbs, this keeps Fuel aligned with the way you plan meals.
If you prefer to track all carbohydrates exactly as listed on labels, leave the setting off.
Net Carbs and your plan
Net Carbs does not create a new calorie plan. It does not rewrite your saved food entries. It simply changes the carb budget view that Fuel uses when it shows your day.
If you want to change your actual calorie or macro targets, use Adjusting Macronutrients.
