Garmin and fitbit calorie counting

[BrianLasiter]

I wear my fitbit all the time. I also use my Garmin 910 to record workouts. I have it connected to my fitbit account which integrates with myfitnesspal.com. Is there any way to tell that fitbit isn't counting calories twice? Say I run from 12:00 to 1:00 and my Garmin reports to Fitbit that I burned 600 calories. My fit bit has also recorded 12,000 steps or so and calculates I burned 600 calories from 12:00 to 1:00.

Will fitbit report 600 calories or 1200 calories to myfitnesspal.com? Fitbit doesn't give an break down on when calories are burned so I can't tell. It does seem like it may over report calories but not by double. Does anyone know how it works?

@BrianLasiter Thanks for being part of our Community! Since, you're using your Garmin 910 and have that account linked to Fitbit then the activities will be double because you're using your Fitbit tracker plus the Garmin 910. We recommend to log just the activities that require more than just steps like tennis or yoga because then the amount of calories burned that you're going to get are going to be more accurate. 

MyFitnessPal will sync activities to Fitbit so every activity that you have in Garmin will sync to MFP and those will go to Fitbit even the activities that are step based. I would recommend unlinking Garmin from MFP or just use it when you're doing activities that aren't step based.
