Versa Lite is tracking my calories too low

[MissCath08]

Out of nowhere 2 days ago, the calories burned are completely different (lower) then they usually are. I haven't changed anything. I did a 10km run and my Fitbit told me I burned 80 calories, which is obviously wrong. Any one else experiencing this or know how to fix it? Thanks

Hi there, @MissCath08. Welcome to the Fitbit Community Forums. Thanks for the details provided in your post about the issue with your calories burned. I understand where your concern is coming from. 

I know you've mentioned you did not change anything, but would you mind double checking if by any chance your settings was changed accidentally? I'd check your personal information to see if your weight and height are properly set, it may be worth the try. To update your profile, see How do I change the units of measurement in my Fitbit account?

Fitbit devices combine your basal metabolic rate (BMR)—the rate at which you burn calories at rest to maintain vital body functions (including breathing, blood circulation, and heartbeat)—and your activity data to estimate your calories burned. 

Your BMR is based on the physical data you entered in to your Fitbit account (height, weight, sex, and age) and accounts for at least half the calories you burn in a day.

Let me know how it goes.
