Should I turn on Negative Calorie Adjustments?

Enabling a negative calorie adjustment from your integration with a total daily calorie partner will give you the most accurate information about your calorie expenditure for the day. A negative calorie adjustment indicates that you are using fewer calories on a given day than our original MyFitnessPal estimate.

To enable negative calorie adjustments in your diary:

• This setting is only available to be changed on the website.  Log into https://www.myfitnesspal.com/account/login
• Click on "My Home" then "Settings" then "Diary settings" 
• Check the box for "Enable Negative Adjustments" then click "Save Changes." 

We recommend enabling negative adjustments if:

• you expect to wear your tracking device consistently
• you would like the most accurate calorie feedback MyFitnessPal can provide
• your device is able to sync its data multiple times over the course of the day

We recommend disabling negative adjustments if:

• you do not expect to wear your device consistently
• you do not want your calorie adjustment to go into the negative (taking away calories to eat)
• you wish to use the device only for the motivational experience of earning additional calories
