I have a constant discrepancy between Garmin Connect and MyFitnessPal in the calories burned for an exercise. I did a 11 mile run yesterday and burned 1428 calories according to Garmin Connect app that is linked to my Garmin 645 watch but the My Fitness Pal app said I only burned 1243 calories under the exercise tab. Which one is more accurate or correct. My weigh and height in both apps match. Am I missing something or do I have to adjust something in the setting for My Fitness Pal.
