Carb Manager imports exercise and health data from a Fitbit device via the Google Health app. **Note: Connected Fitbit to Carb Manager before?** Google is updating how Fitbit shares data with apps like Carb Manager, so you'll need to reconnect Fitbit using your Google account to keep your data syncing. For steps, see [Keep your Fitbit data flowing into Carb Manager](https://help.carbmanager.com/docs/keep-your-fitbit-data-flowing-into-carb-manager). On iPhone, you can also bring your Fitbit data in through Apple Health. The same article has those steps. ## Data that is shared Carb Manager imports the following information from Fitbit. - steps - exercise minutes — includes time engaged in any activity above 3.0 metabolic equivalents (METs), where 1.0 MET equals the energy used while resting - exercise calories/kilojoules burned — is calculated using Fitbit's energy burned from total activity, including basal metabolic rate (BMR) and subtracting the BMR portion of calories burned - weight - body fat % - sleep — includes overall tracked sleep time minus your time spent awake and restless **Note:** For more information about data that is imported from a Fitbit device, see Fitbit's documentation: - [How does my Fitbit device calculate my daily activity?](https://help.fitbit.com/articles/en_US/Help_article/1141.htm) - [How do I track my sleep with my Fitbit device?](https://help.fitbit.com/articles/en_US/Help_article/1314.htm) **Note about calorie/kilojoule calculations:** The total number of calories/kilojoules burned that is displayed in your Fitbit device will be different from the total that appears in Carb Manager after Carb Manager imports the activity. In Fitbit, calories/kilojoules burned include basal metabolic rate (BMR) plus calories/kilojoules burned through exercise minutes. Because Carb Manager only imports calories/kilojoules burned through exercise, Carb Manager subtracts the BMR from the total calories/kilojoules before displaying the results in your daily log. Carb Manager exports the following information to Fitbit/Google Health. - recipes — includes the name of a recipe and the calories/kilojoules and macros for the entire recipe - meals — includes the category for which you logged it (such as Breakfast or Snack), a calorie/kilojoule summary, and a macro breakdown for the day **Note:** Food, recipe, and meal data isn’t being sent to Google Health right now. It will sync again after an upcoming Carb Manager update. ## Connect Fitbit to Carb Manager 1. Ensure the mobile device or computer where you use Carb Manager is connected to the internet. 2. Make sure Carb Manager is updated to the latest version. If the update isn’t showing in your app store yet, check again shortly. 3. [Sign in to Carb Manager](/docs/sign-in-and-out-of-registered-carb-manager-accounts). 4. Go to [Embedded object](https://cdn.document360.io/39f753db-7167-486f-a297-e9dee7536f7d/Images/Documentation/avatar-menu-settings.svg) **Settings**. 5. In My Settings, select [Embedded object](https://cdn.document360.io/39f753db-7167-486f-a297-e9dee7536f7d/Images/Documentation/settings-app.svg) **App Settings**. 6. Optional: If you plan to consistently log exercise, Carb Manager can automatically deduct energy (calories or kilojoules) and macros from your daily totals based on the energy burned from active exercise. In the Macros Settings section, turn on **Enable Calories/Kilojoules Burned** and, optionally, **Enable Macros Burned Deduction**. For details, see [Deduct energy (calories or kilojoules) and macros when you log exercise](/docs/deduct-energy-calories-or-kilojoules-and-macros-when-you-log-exercise).**Important:** If you turned on the option to [deduct energy (calories or kilojoules) when you log exercise](/docs/en/deduct-energy-calories-or-kilojoules-and-macros-when-you-log-exercise), be sure the [activity level](/docs/en/update-your-activity-level) you selected in your profile matches your daily lifestyle and your intention to log activity from a synced fitness device or app. If you previously set a high activity level because you exercise and your daily activity primarily consists of exercise that you intend to log in Carb Manager, then select **Sedentary** as your activity level to ensure Carb Manager doesn’t count the energy that you burn twice. 7. Go to the Health & Fitness Device Links section and select **Fitbit**. 8. Follow the on-screen instructions to sign in with the Google account linked to your Fitbit. Select **all** (or select the specific health data you want to share), then tap **Continue**. Now, when you view a day in Carb Manager’s daily log, Carb Manager and Fitbit/Google Health share wellness data if data is present. For details, see [View wellness data from a fitness device or app](/docs/view-wellness-data-from-a-fitness-device-or-app). **Tip:** If you have problems connecting Carb Manager to your Fitbit device, see [Troubleshoot issues from a fitness device or app](/docs/troubleshoot-issues-from-a-fitness-device-or-app).
