Don’t understand calories burned

[Redlionny]

Just received Inspire HR yesterday and set it up. Wore it to bed and when I woke up and walked about 5 paces it said that I had burned already 576 calories for the day so far? That doesn’t make sense to me. Even now with just walking to work and a desk job it says I have burned close to 1000 calories today (it’s not even noon). 

That can’t be right. Can someone explain bc I really want to get an accurate (or relatively accurate measure of calories burned) for my workouts. 

Thanks

Fitbit includes BMR (basal metabolic rate) calories, those calories you are burning just by being alive.  When you woke up this morning, your body had still been breathing, pumping blood, etc which all burn calories.

See How does Fitbit estimate how many calories I've burned?

I know people smarter than me made this but this logic seems flawed. If I eat 2000 calories per day and my BMR is 1850 I only need an extra 150 calories to burn what I've eaten. I'm definitely not burning the 4500 calories that it shows. I understand the resting BMR but these numbers are impossible I can't be at a 55% deficit daily.

@OliverM3  You are making your post more confusing by quoting a bunch of extra numbers.

Bottom line, is your point that fitbit says you are burning 4500 calories per day, but that seems too high?  If so, are you sure you are really reading that right, that fitbit says that is what you are burning in a day?

Yes it's showing 4500 calories burned. So take yesterday which showed the 4500.  I exercised and it showed 480 calories burned. 

if I were to add it in to the base BMR that it shows of 1860 that's still only 2340 calories burned for the day 2340 would be realistic.  This is what I see which is an impossible number for one 480 cal exercise.
