    Some people on the fitbit user group here suggested

    http://www.myfitnesspal.com/topics/show/946130-fitbit-bmr-rmr-tdee?hl=Fitbit+bmr#posts-14419479

    Not sure if its what you are after

    Or another example I woke at 7am and my burn on fitbit was 390

    390/7=55.71( per hour). 55.71x24=1337

    Thank you, good info on what they are testing.

    FitBit's FAQ actually says they use Harris BMR, as they mentioned MFP uses Mifflin. Depending on amount to lose, they can be close, they can also be off by 200-400.

    I figured they do use BMR as sleep time calorie burn, thank you for confirmation.

    But there really isn't a way in the data to see what might have been burned during a 1 hr sitting session, right?
    Or do some of the models with stop watch allow to make an event that you can later view calorie burn on just that time?

    Hmmm.

    Oh, if you want to inform that group what the fix is to get MFP to match up.

    Just as the beta-spreadsheet in that link does.

    Point them to that beta-spreadsheet link, I'd love any feedback on it. FitBit seems a more successful potential correction and usage, as long as you reset your stride length to correct, which should but probably wasn't done initially.

    I have the fitbit one model and yes you can use a stopwatch function to make what they call an activity log. You hold down the button on the fitbit for a couple of seconds. When I do an activity that fitbit does not accurately measure I use that function. So when I do a spin class or nrolfw it will show time started, duration, cal burn, distance(which for a spin bike will be off), steps, pace, floors.

    Then I log my activity on mfp with the start time given and duration and I enter my HRM burn....yes I know it can be flawed but it is definitely closer than what fitbit give me. Im sure you know the rest, they "talk" to each other and override the fitbit burn.

    I'll pass it on to the fitbit group for you.

    I just had to join and explain it. Mostly because I might be back again!

    Heybales - here is a screen shot of part of my Fitbit dashboard which shows the calorie burn throught the day. You can see it in 5 minute blocks:

    Well, cool doggies, it can do that like BMF then.

    So does BMR around 1152 sound right for you? Based on that 5 min block anyway.

    And does some sitting down time at work show the same 4 calories in 5 min usually?

    Mine shows that I burn 6 calories for every 5 minutes of sleep or inactivity.

    At 6 calories per minute, my BMR would be 1,728.
    At 5 calories per minute, my BMR would be 1,440.

    My Roadmap spreadsheet gives me a BMR of 1,497, which is approx. 5.2 calories per 5 minutes.

    To add even more info ... and maybe a bit more confusion to the conversation, there are Fitbit "burns" listed on the website for days BEFORE I owned and wore the Fitbit. These must be based on my weight at that time.
    In January, I get a burn of 1661. (1530 on the spreadsheet)
    February 1650. (1510 on the spreadsheet)
    Mid-March, just a couple days before I owned my Fitbit, it gave me a burn of 1625. (1505 according to the spreadsheet)

    (Note: The spreadsheet dates to not exactly correlate with the Fitbit dates for that month.)

    Not sure if a BMR of 1152 is right - it isn't what the calculators would say - female, 5'1", 163#, 51 years old - I have manipulated the fitbit to show I am 100+ years old because I think my metabolism is suppressed so I"m playing with that function - trying to not get an inflated TDEE. Right now I'm upping my calorie intake 50-100 calories every 3-4 weeks trying to find my TDEE that way so I can re-adjust the FB settings. I thought, however, that a screen shot of the dashboard would help you.

    During some relatively quiet periods at work yesterday, I had primarily 4 calorie blocks with a few 5 calorie blocks - may have been when I stood up to get something or stepped across my office. I also get the 4 calorie blocks when sitting quietly such as when watching TV.
