Calories are wrong between Fitbit and MyFitnessPal

[Lori1971]

Just today, Fitbit is picking up multiple readings for lunch calories from MyFitnessPal. Today should read 476 but instead it shows over 3000. Did it update?

Welcome to the Fitbit Community @Lori1971, hope you're doing great! Based on your profile settings (which should be the same in both Fitbit and MFP) the system expects you to burn a certain amount of calories per day. If your activity is lower than expected then you will burn less than that.

If the negative adjustment is on then Fitbit will tell MFP that you have been less active and will reduce the calories you can eat. If it is not set on then it won't adjust the calories down in this case. Whatever it is set to, if you are more active than expected then Fitbit will tell MFP and it will raise the calories you can eat.

Said that, MyFitnessPal pulls your calorie burn directly from Fitbit's total daily calorie. We then project forward to the end of the day based on your calorie burn so far. If this full-day number is different than MyFitnessPal’s estimate for your daily calorie burn, an adjustment will be made to your caloric intake goal. This adjustment can either be positive or negative. If the adjustment is positive, this indicates that your calorie burn for the day as reported by Fitbit is greater than MyFitnessPal’s estimate. If the adjustment is negative this indicates that the partner's reported calorie burn is lower than MyFitnessPal’s estimate.

Since the adjustments are made on MyFitnessPal you should activate the negative adjustment in Fitbit by doing the following: 

Log in to the full MyFitnessPal site at www.MyFitnessPal.com and click the main "Settings" tab, then "Diary Settings." Check the box for "Enable Negative Adjustments" then click "Save Changes.” If you are typically unable to sync your device until late in the day, you may wish to leave negative adjustments "off." You can learn more about the adjustment here.

In case that your both apps are not syncing correctly, I recommend to unlink the accounts and them link them again. Doing this should be able to resolve any issues between the account.

To do that, follow these steps:

1. Sign into your Fitbit dashboard.
2. Go to the Applications settings on your account.
4. Under MyFitnessPal, click "Revoke Access."
5. You can then re-link the two accounts.

PS: I moved your post to the Third-Party Integrations as there are more chances to get app related replies here.

Hope this helps, let me know if you need further assistance!
