Calories burned accuracy

[Brontekj]

Hi there,

just wondering if there’s anything I can do to make the calorie burning tracker more accurate on my Fitbit? 

When I go to the gym and do a HIIT workout I wear a heart rate monitor around my chest which stays I burned around 500 calories but my Fitbit only says 200ish?? Is there a reason why it’s so different? 

Thank you 🙂

Hi @Brontekj, welcome to the Community Forums! 

I appreciate the information that was shared in your post. Let me share with you that your basal metabolic rate (BMR) is the rate at which you burn calories at rest just to maintain vital body functions like breathing, heartbeat, and brain activity. Your BMR usually accounts for at least half of the calories you burn in a day and is estimated based on the physical data you entered when you set up your account: sex, age, height, and weight.

The calorie burn estimate that Fitbit provides takes into account your BMR, the activity recorded by your tracker, and any activities you log manually. Keep in mind that we do not recommend our users to compare Fitbit products with other devices because they'll use different algorithms to track data. 

Let me know if you have any additional questions.
