So confused Fitbit Calories Vs MFP Calories

From my experience . . .
You or MFP set the calories for this site. The only time they would change would be if exercise calories were added. You are "promising" you are going to burn a certain number of calories. However, Fitbit is a more fluid method of tracking calories. It will adjust calories throughout the day based on actual calories burned.

I looked at my average calories over a week on Fitbit and used that to set MFP (1750). On a normal day, I am pretty close to that number on both. On days I am less active (usually Sunday) MFP doesn't know that, my Fitbit does. There are two ways to deal with this. The first would be to meet the 1750 every day and it will even out over the week. (I do check that average weekly to see if there is any change). You could also just follow the number on the Fitbit to determine how many calories for the day. It is definitely more difficult to plan what you eat ahead of time, but is more accurate (especially if you have unexpected things happen that affect the end of your week).

I have the two linked, but they are giving me very different figures!

An example yesterday on fitbit it said 210 cals over ! but on mfp 617 remaining?!?!

Please help!

Many Thanks

Sounds like there could be a couple of things going on:

1) You have a different target set up on MFP compared to Fitbit (i.e. I have a 1.5lb a week goal set up on both, so a deficit of 750 cals daily).

2) Your timezones are not the same on both sites (so that at the end of your true day when Fitbit has recorded the whole day MFP still thinks you have more hours left and tries to add on more calories)

3) You have your activity level on MFP set up to too high a level, without having negative adjustments turned on

Have a look at your settings and see if any of the above are true?
