How to connect and sync MyFitnessPal (MFP) with Fitbit

MyFitnessPal app and Fitbit app on iPhone

If you are trying to lose weight (or gain it) or track your calorie intake for other health reasons, connecting MyFitnessPal with your Fitbit is a great way to track your calorie intake accurately and calories burned. 

Although the Fitbit app has its own library of food items, connecting your Fitbit to MyFitnessPal gives you access to one of the largest food databases (over 2 million listed foods) and MFP’s unique daily food tracking system.

MyFitnessPal has a more comprehensive selection and a more in-depth focus on diet monitoring than the Fitbit app. So by connecting the two, you get a better understanding of how both your diet and your calorie burn impact your overall health.

You can link your Fitbit account from MyFitnessPal’s website, as well as the MyFitnessPal Android and iOS apps. Here’s how.

I connected Fitbit and MyFitnessPal. Now what?

After successfully connecting Fitbit and MyFitnessPal, there is some housekeeping to do to make sure you get the most out of this integration.

  • Time Zone. Verify that your time zone settings are the same in MyFitnessPal and Fitbit by checking that your location is the same. 
  • Activity Level. Make sure you set the appropriate general activity level in MyFitnessPal to match the activity level you engage in using your Fitbit.
    • In the MFP app, select the More or Menu button and tap Goals to view and change this. Tap Activity level and choose from Not Very Active, Lightly Active, Active, or Very Active. Update your activity level in MyFitnessPal app
  • Logging Food. After linking the two apps, only log your food in MyFitnessPal and stop logging food in Fitbit (unless you chose not to share that information with MFP.)
  • Logging Exercise. Since you connected your Fitbit to MyFitnessPal, you should no longer need to log your step-based exercises manually. You may need to enter other types of activities into MFP manually.
  • Wear your Fitbit throughout the day. To get the credit for your workouts AND your regular activity (like climbing steps and non-workout walking), make sure you always wear your Fitbit.
  • Calorie adjustments from Fitbit activity. To get credit and calorie adjustments from your Fitbit activity, make sure you sync your Fitbit with the Fitbit app throughout the day. And don’t forget to sync at the end of your day before you go to bed. Your evening calorie adjustment and activity data show all the effort and activity you did during your day. 

If you use other fitness or health apps, like Strava or RunKeeper, do not connect them to Fitbit and MyFitnessPal. If you do, you might see duplicate data. Instead, link that app to either MFP or Fitbit, just not both.

Check if MyFitnessPal and Fitbit are syncing

Once you connect both accounts and verify that both apps use the same location and other housekeeping, it’s time to use the two services together!

Just keep wearing your Fitbit and get active! If you are away from your phone, make sure you occasionally are near it so your Fitbit can sync with the Fitbit app and send that information to MFP.

Every time you sync your Fitbit device with the Fitbit app, Fitbit then shares and sends that data to MyFitnessPal. And MFP uses that Fitbit’s shared data to update your remaining calories throughout the day.

How to know if MFP and Fitbit are syncing

  • Compare your Fitbit app’s Today tab information to that shown in MFP’s Daily Summary or Calories Remaining summary. The listed steps should be the same. Check that MyFitnessPal and Fitbit are syncing correctly
  • If the information does not match, open the Fitbit app and sync, then wait 15 minutes or so for the MFP sync to go through.

MyFitnessPal says another MyFitnessPal account has already been linked to this Fitbit account Another MyFitnessPal account is linked to Fitbit

You can only link one Fitbit device and one Fitbit account to MyFitnessPal. Similarly, you can only connect one MyFitnessPal account to your Fitbit account.

When you get a message that another MyFitnessPal account already has access to your Fitbit, you need to unlink that MyFitnessPal account first. You likely have more than one MFP account–each associated with a different email address.

If you can, log into your old MFP account using your past email address and follow the steps above to disconnect your account. 

If you don’t know which email you used in the past, search your email and see if you can find an email from MyFitnessPal with the email or username you previously used.

And when all else fails, try contacting MyFitnessPal’s customer support MyFitnessPal app contact support in Help menu

  • Choose More > Help > Contact Support in the MFP app.
  • Go to My Home > Settings > Contact Us on the MFP website.

Delete that old MyFitnessPal account

Deleting an account removes all its data, including all your food, step, and weight entries, your workouts, notes, newsfeed posts, and photos.

To delete an MFP account, you need to know the email and its password (or reset the password, as long as you have access to that email.)

  • Log into the MFP website, choose the My Home tab, and select Settings in the submenu. Choose Delete account and confirm.
  • Delete from the MyFitnessPal app
    • For Apple devices, go to More > Help >Delete account. Delete MyFitnessPal account from the MyFitnessPal app
    • For Android, go to the Menu > Help > Delete account.

Don’t remember your old email address or don’t have access?

If you can’t unlink an old MFP account from Fitbit, try using another app in the Under Armour (the owner of MFP) family, like MapMyFitness, MapMyWalk, or MapMyRun.

  • Download one of these apps and create an account.
  • Then connect that app to your current MyFitnessPal account.
  • Once those apps are connected, connect that new app to your Fitbit account. See if they now link to your Fitbit across the apps.

Can’t sync MyFitnessPal and Fitbit? 

MyFitnessPal usually syncs data within 15 minutes of activity, but some technical issues may prevent the sync between the two apps from being immediate. 

Occasionally, there are backlogs of Fitbit data sync requests, resulting in your data not showing correctly during the day.

So one of the best times to check MFP is at the end of the day. Usually, by the evenings, those Fitbit sync backlog issues are worked out!

It should never take more than 24 hours for your Fitbit data to sync with MyFitnessPal. And usually, it’s a lot less!

Suppose your data isn’t syncing, and you’ve waited until the evening or the next day. In that case, it’s a good idea to check if MyFitnessPal is experiencing longer than usual sync delays or an outage by looking in the announcement section of their FAQ page. 

If there are no disruptions listed in the MyFitnessPal announcements, try to sync MFP with your Fitbit manually. To do this:

  1. Sync your Fitbit with the Fitbit app and wait for the Today tab to update with your latest information. You can manually sync your device inside the Fitbit app using Sync Now option under your device’s settings. Sync Now feature in Fitbit app
  2. Manually add a cardio exercise to your MyFitnessPal diary, such as walking for two minutes (you can delete the entry later). Manually add exercise to MyFitnessPal
  3. Within 15 minutes, this should force a sync with your Fitbit.

Think your Fitbit calorie adjustment is wrong, shows 0, or is it even a negative number?

MFP recalculates your calorie adjustment each time the Fitbit app sends and shares new data from your Fitbit device. Consequently, that calorie adjustment number changes throughout the day as you go through periods of activity and rest.

The best time to check adjustments is at the end of the day. It’s only at midnight that your projected and actual numbers should match–because all your periods of activity and rest are now complete.

By default, MyFitnessPal only adds calories to your calorie goal using shared activity from your Fitbit. 

However, MFP lets you turn on an optional feature that removes calories from your goal if you are less active than usual. This feature is your negative calorie adjustment and is the reason you may see zero or even a negative number for your Fitbit’s calorie adjustment. 

You can turn negative calorie adjustments on or off via the MyFitnessPal website only (not the app.) Find it in My Home > Settings > Diary settings > Enable Negative Adjustments. Fitbit negative calorie adjustment for MyFitnessPal

Suppose you don’t turn on negative calorie adjustments. In that case, you see a zero adjustment if you just started your day and haven’t engaged in an activity to earn more calories than your baseline MyFitnessPal food goal.

Even when your Fitbit’s calories adjustment is zero, your accounts may have synced. So go into the details of your adjustment. 

  • Click the “i” information button under the Fitbit calorie adjustment line on the MyFitnessPal website. Fitbit calorie adjustment details in MyFitnessPal
  • Tap directly on your calorie adjustment in the MFP app to view additional details of your day’s calorie adjustment.
