Calories burned from walk too high + myfitnesspal issues?

[Ullish]

Hi guys, I'm quite new to all of this calorie calculating and fitness business haha. I'm 27, 88kg and 173cm tall

For the past few weeks I've been using myfitnesspal and mapmywalk to calculate incoming calories and calories burned on a walk/run, if I'm at the gym using a treadmill/bike I just take the calories it says I've burned.

I bought the Charge 2 to make this whole process a little easier as I really like the myfitnesspal apps simplicity but it seems that I'm burning an insanely high amount of calories on a walk now?

Using the mapmywalk app I went for a 40 minute jog/walk yesterday and that app told me I burned 307 calories. Today I went for a 20 minute casual walk and Charge 2 told me I burned around 273 calories?? How is this so high for that particular workout?

Also when this synced with myfitnesspal it came in at only 227calories of exercise

I'd really like to keep using the myfitnesspal app so can someone please explain this to me? I'd rather be under counting my calories than over counting on that app (eg only my workouts) so that my remaining calories are nice and limited

Hello @Ullish, it's nice to have you here in the Fitbit Community. Keep in mind your tracker is reading all your motion patterns along with the intensity you invest on your exercise, so it is possible that for a shorter period of exercise your calorie burn rate increased, since your tracker is reading all the small changes in the intensity of your exercise using the PurePulse sensor to read your heart rate more accurately causing your calories rate being more precise.

If you are noticing calories fluctuation with MFP while you are using your Fitbit account, it's important to mention also when there is a difference in calorie estimations between Fitbit and MFP, MFP makes a "Fitbit Calorie Adjustment". For more details take a look at this post.

Hope this information helps. Let me know if you have additional questions.
