Fitbit & MFP wildly different calories

[NoGoodPunsLeft]

Hi, I've been tracking food & exercise for a few weeks to try to lose a bit of weight but realised this week that the calories in MFP & my Fitbit are wildly different, for example:

28 minute run
MFP 491
Fitbit 245

7 minute walk
MFP 22
Fitbit 160

Which is right?!

MFP wildly overestimates calories burned. The only time I never lost weight was when I logged my exercise and ate back the calories MFP gave me. I read on previous threads that lots of other people found this too, it’s better to just not log exercise.

No clue how accurate Fitbit is.

I have noticed this too.
I wear Fitbit and DH has Garmin. We currently sharing an office and go for a walk together at lunchtime. We sleep in same room and share a bathroom so basically should have Same amount of steps at end of the day. It's a standing joke that I'm always about 2000 more than him by end of every day ( my 14000 to his 12000 ) we have same left length so it really should be the same !

Does the Fitbit send your workouts to MFP or are you inputting the exercise using MFP own measurements? Also does the Fitbit have a heart rate Monitor? I’d think the Fitbit is more likely to be the realistic one, especially if it has access to heart rate while exercising.

Thing is you have to remember they’re all estimates. It’s not an exact science
