Difference in FitBit Calories vs. MyFitnessPal Calories kriskitty10 — Jan 04, 2017 05:08PM PST

Something seems off with my FitBit calorie adjustment and I'm wondering if you can look into it for me?

Example from this week:
Jan 2 - 8,560 steps - FitBit app shows burned 1813 calories - MFitness Pal reflects +118 calorie adjustment
Jan 3 - 6,698 steps - Fitbit app shows burned 1793 calories - MFP reflects -116 calorie adjustment

Does a difference of 1,862 steps really equate to a 234 calorie difference in MFP? Fitbit App showed a 20 calorie difference.

Hi kriskitty10,

Thank you for taking the time to contact us. I have reviewed your account and everything seems to be syncing as expected. The 1862 step count difference is not the only factor taken into account when calculating your daily Fitbit calorie adjustment, and is not what is causing the adjustment difference. The step count and your daily calorie burn from those steps is sent to us from Fitbit, where we then take into account any exercises logged into your MyFitnessPal exercise diary and compare it to your estimated calorie burn projected by MyFitnessPal (based on your information and activity level entered into your profile).

To break it down:

If you look at your diary for 1/2, and click on the “i” next to the adjustment, you can see that Fitbit sent us a calorie burn of 1817, and that your projected MyFitnessPal Calorie burn was 1699.
The difference between the two is your adjustment (1817-1699 = 118), resulting in the 118 calorie adjustment.

Looking at 1/3, we see Fitbit sent us a calorie burn of 1826 and your projected MyFitnessPal Calorie burn was 1942.
The difference between 1/3 and 1/2 is that you also manually logged a yoga exercise w/ a 244 Calorie burn. So if you look at the exercise projected by MFP (1698 + logged yoga 244), we get a total MyFitnessPal projection of 1942.
Now, following the same adjustment question, we subtract your estimated MyFitnessPal calorie burn from the estimated calorie burn sent from Fitbit (1826-1942 = -116), and receive the calorie adjustment of -116.

Hope this helps clarify! We wish you the best of luck in meeting and maintaining all your fitness goals!
