Why does My Fitness Pal always deduct significant calorie expenditures

[Anonymous]

I have a Garmin and have is synced with MFP. While I know that the calorie estimates in fitness trackers can be way off, I don't understand why the Garmin will show, for example, 500 calories burned for an activity while MFP assigns a negavtive amount like -350 for the same activity. I have googled and looked at MFP, but my pea brain still doesn't comprehend. Anyone have an idea how this works?

MFP is based on net cals. So if your goal is 1800, and you eat 2000 and exercise -200, you've netted 1800, or reached your goal.

This is OP-

I understand that part PP, but when MFP factors in the exercise it is WAY off from the Garmin which I am wearing. So Garmin will say something was 500 calories of exercise and then MFP will show a negative -275, and I don't understand that metric:

So Goal 1,330 calories-1400 (actually eaten)- 130 exercise= -200 over


I am not understanding that - 130 exercise part.

OP again, MFP is calling it a "Garmin connect calorie adjustment"

I'm not sure but have you asked on myfitnesspal boards? Might have better luck there.

If your goal is 1330, you ate 1400 and exercised off 130 of those calories, but MFP is showing "-200" in red as the end of the equation, then it sounds like it's adding your exercise calories as food calories (adding them rather than deducting them). If it was correctly computing, you would have 60 calories left in your daily limit, shown in green at the end of the equation.

I had problems when I synced my Garmin with MFP. One day, I exercised for about 80 minutes total (hard exercise but only 80 minutes), and then went about my normal day. Garmin had me at burning 4500 calories that day! I realized the problem was it was adding 1500 baseline calories from MFP to the total burn Garmin had recorded. I unlinked the accounts and everything went back to normal. MFP worked great with my FitBit, but it seems to have issues with Garmins. *I have a Forerunner 235.

So what's the status on a reply from Garmin on this Connect/MFP issue?

It basically renders the link between these two apps (and thus the use-case of using a Garmin vs. just using the step counter on your phone) useless.
