MFP and Fitbit Offset

jerryvo

Sorry for the redundant question as I have seen several fitbit calorie adjustment threads, but I just can’t wrap my head around what is happening.

I am set up in MFP as sedentary with a goal of 2 lbs per week of weight loss. This gives me a net calorie goal of 1790 for the day.

Fitbit shows I burned 3281 and has a projection of 4255. I have looked at my fitbit dashboard and verified that the 3281 includes my lunchtime workout. Fitbit calculates it at burning 440 calories but I calculate it closer to 375 (Samsung gear S2, heartrate monitor, elliptical calculation, etc..)

MFP shows I burned 3198 including 375 manually entered from my workout

The difference is 1057 so I understand this is my offset. However under Exercise it shows my 1057 plus the 375 from my workout showing I burned 1432 from exercise and have 2288 remaining calories from my goal of 1790 (eating 934 so far). If I remove the workout from MFP the MFP estimate for calories burned just drops by that amount and the offset goes from 1057 up to about 1400 so I am left with the same total workout calories.

It seems to me since the fitbit calorie estimate already includes the workout and the mfp estimate also includes the workout my calories burned should be 1057 and it should not be adding the 375 on top of that. I cant imagine eating a 2200 calorie dinner.

What am I missing? Can someone please help explain this to me.
