Inaccurate calories

Replies are disabled for this topic. Start a new one or visit our Help Center.

I bought a Fitbit Inspire HR on Friday and charged it. Before I even put it on on Saturday it said I'd burned 500 calories. It also showed 38 minutes less exercise than I had done. The store I bought it from won't give me a refund.

The calories may be correct.

 

As well as tracking calories burned through activity your fitbit also tracks your BMR calories. These are the calories you burn just keeping your body alive (even when asleep). They are calculated from your profile settings for age, height, weight etc so you needn't be wearing your fitbit to get them. What you are seeing includes the total BMR calories burned since midnight.

Thank you. 500 while sleeping?

It could well be. The actual amount depends on your age, weight etc but for me the total BMR calories for a full 24 hours is around 1440. For many people they add up to more than calories burned through activity. Here's what fitbit have to say: Help article: How does Fitbit estimate how many calories I've burned?

Thank you. How about the inaccurate number of minutes? I worked out for an hour and a half but only 52 minutes showed.

Are you talking about the number of active minutes tracked? If so, then you only get those when fitbit thinks you have been very active. It may just be that for some of the time it didn't think you were working hard enough. See: https://help.fitbit.com/articles/en_US/Help_article/1379/

Hi. I'm still not convinced. Yesterday I did a Body Pump class and it said I burned around 300 calories. It said I burned 2500 for the day. It just seems wildly inaccurate.

Hi. Yesterday it said I walked 13km which wasnt accurate either. Deeply disappointed with the product.
