Fitbit vs Garmin step calorie adjustment dervari — Aug 06, 2017 07:11PM PDT
So, my Fitbit died and I made my Garmin Fenix 3 my primary step counter. Well, I was getting anywhere from 300-1400 calories/day adjustment using my Fitbit. For example:
5734 Steps, 1026 calories
4904 Steps, 861 calories
6163 Steps, 702 Calories
Since I've switched to Garmin....
7323 Steps, -74 Calories
5734 Steps, -137 Calories
Any ideas on the wild discrepancy? Fitbit was a Charge HR, Garmin is a Fenix 3.

Thank you for contacting us with your question. Even though fitbit and Garmin each have their own formula for calculating your calorie burn, it looks like the difference for you is due to the individually tracked exercises. Fitbit only sent us your total calorie burn and not your individual exercises, however, Garmin sends both. It is important to take a look at how an individually logged exercise affects your adjustment.
If you click on the Garmin Calorie Adjustment line in your diary, and then on Extra Calories Earned, we can look at the Garmin calories vs the MyFitnessPal Calories Burned. In order to see an adjustment the Garmin number must be higher. When you add a individual exercise entry, the program replaces your tracked activity and calorie burn with the calorie burn from that entry, to avoid receiving double credit for the activity. In your adjustment detail it gets added to the MyFitnessPal number, since it was not tracked by your Garmin device, reducing your Garmin calorie adjustment by the amount of your individual exercise entry. If this makes the MyFitnessPal number greater the adjustment will go back to 0 (or negative when enabled) until the Garmin number once again passes it, however, if you look at your calculation at the top of the home screen, you will see that you are getting credit for the individual exercise entry there.
