Does a Fitbit exercise session only include calories burned or adds in BMR Calories?

[Zaki03]

Hey so I burn according to my fitbit 48 calories per hour at rest, when i start an exercise with my fitbit, lets say i take a 1 hour walk and then press Finish, the summary shows i burned 200 calories, but is that only calories burned from my walk or was that including 48 calories burned as my basal metabolic rate?

Hope that makes sense?

thanks x

Should include BMR. You can easily verify that by taking note of calories burn in the app at the start and end of the exercise. The difference should match the exercise record - or at least really close.

I'm about ready to hit the treadmill - I'll let you know what I come up with.

I tested that once my saying I was going for a walk, then sitting. or maybe I was lying down, still for 10 minutes, then ending the walk.  For the workout, it said I was burning at my BMR.  If BMR was not included, I would have expected it to be close to zero.  So I concluded the workout includes BMR calories.

@JohnnyRow - Duh! Great way to check it out! Without working out!

@Zaki03 - Now that my Senior Moment is over - the results of my test. If nothing else, you have two tests to support that exercise calorie burns include BMR.

At 2:32 pm PDT, I was at 1,652 calories. After taking the first screenshot of my apps Today screen, I immediately started a Treadmill exercise on my Versa 2.

At 3:32 - at exactly one-hour "on the clock", I stopped the treadmill exercise and immediately took a second snapshot of the Today screen.

The calorie differences between those two screenshots is 410 calories while the exercise record states 411. I believe the one calorie difference may be because I started the exercise approximately 10 seconds after the Today screen updated at the "top of the minute" - meaning it includes 10 seconds of "BMR only" burn. If I had started at exactly 2:32, the numbers would probably match. Or, it is a very small rounding difference.

The images below support the prose, above. 

Good luck - and welcome to the boards.
