My Fitbit has recently started recording fat burn at anything over 78bpm where previously it was anything over 80bpm ! 
I use my Fitbit to track a heart condition and this is screwing with my data ! Anybody tell why this has changed??

Heart rate zones used to be based only on max heart rate.  That has now been adjusted to be  more accurate, taking resting heart rate also into effect now.

You can read more about this at How does my Fitbit device calculate my heart-rate zones? 

Before posting, re-read to see if it would make sense to someone else not looking at your Fitbit or phone.
