Calories from Garmin

Hi there- new user here after deliberating between MFP & Cronometer and going with Cronometer :)

I have a Garmin Vivoactive 4, but when I look at my Cronometer dashboard there is a huge difference between the calories for today so far between my watch (1,360) and Cronometer (2,343). The split between resting & active is also way out. Shouldn't Cronometer be importing calories burned direct from Garmin? Whats the reason for this discrepancy?


  • Hi RobCork,

    Cronometer will show your total calories burned for the day - in other words, the number of calories you will burn over a 24-hour period. Calories burned from exercise will be added to this number as you import them into your diary from Garmin. If you look at a previous day in your Cronometer diary, are the numbers closer?

    Another thing that can cause a higher calories burned in your Cronometer account could be your activity level settings in your Profile. If you are using a device to import your exercise calories, we recommend setting your activity level to none in order to avoid double-counting calories.

    Please let us know if these don't solve the discrepancy you are seeing - that is quite a big difference!

  • Hey, Karen- many thanks for your reply. I understand and I’ll check tomorrow (this is my first day using so no history to check yet), also you were right- the Garmin activity was being doubled up by Cronometer. Thank you!

  • Hi again

    The first issue is fixed- active calories are now 100% agreed. But having checked the daily totals it’s the non active calories that are out quite a lot:

    Garmin Connect:

    Resting= 2,568

    Active= 280

    Total= 2,848


    Resting: 2,113 (455 out)

    Active= 280 (no difference)

    What could be causing this, could you help? Delighted with everything so far, would be good to get this agreed though. Is it something to do with BMR setting? I’m using that automatic macro in Cronometer for sure.

    Many thanks


  • Hi Rob,
    We have recieved other similar reports of an issue like this with Garmin. Would you mind sending a couple of screenshots along to [email protected]? Please include screenshots of your Cronometer diary as well as your Garmin diary clearly indicating the numbers which contain a discrepancy.
    Thanks for all the details! This well help us get to the bottom of the issue!

  • Hi Hilary, thats done, thank you.

    For what its worth, here's my take on it...

    Cronometer uses the default calculation based on BMI etc, and that isn't adjusted unless we put a factor in, I have set to 'none' as I have the Garmin tracker. It appears that Garmin however applies a 1.2 multiplier to the BMI calculated resting calories, so whereas for me Cronometer had a total of 2,113 yesterday, Garmin had 2,568.

    Cronometer resting= 2,1113
    Apply 1.2 multiplier= 2,535- Garmin resting calories= 2,568- difference is now about 30, too small to worry about I'd say.

    If thats the case then Cronometer has to be the 'correct' app for monitoring overall calories, with Garmin focussing on the input of 'active' calories into the total.

    I have MFP synced to get target calories from Cronometer into Garmin, but I don't think thats of any relevance here as that will just contribute to the daily calculation of calories consumed as opposed to measuring calories burned.

    Does that make sense? Maybe I'm wrong, I'm new after all :)
