    My own realization with the charge HR was not to log my exercise. I just put a post on my page for what I have done and let the fitbit adjust my cals. I was maintaining and then gaining! I figured out why! It was doubling my burnt cals between the fitbit and mfp. I am now losing again! Love my fibit!

    Hi I have had my fitbit for a few weeks. I was to see how many calories I'm burnig during workouts. Is it okay to press the timer to capture those workout sessions? I wont enter exercise on mfp. Just not sure it the calries will be messed up leaving me more calories left over to eat than I need.

    Pressing the button won't affect logged calories at all.

    Lots of people worry about double logging exercise calories, but very few people actually have it happen.

    That button press on the device merely takes a snapshot of the stats for that block of time - rather than buried in with the daily stats. It doesn't change any stats.
    That way you can review workouts later. You can add notes to them too for that later review.

    Like heybales and NancyN795 said, the button just marks the time of the activity so that you can see the details of that activity period, rather than having it blend into the day.

    With that said -- and it's been a while since I've messed around with the particulars of this -- an activity recorded on Fitbit will sync over to MFP as a distinct exercise event, so you don't want to add a separate activity on MFP as well, because that could cause some duplication.

    I think that might be what princessofredrock was referring to; however, entering activity on MFP should over-ride any activity recorded by Fitbit during the same period so, as long as the start/stop times match up, duplication shouldn't be an issue even there.

    ... someone else may be able to confirm/clarify the details here -- like I said, been a while since I've tinkered with that piece of the sync functionality. :)

    No, an activity recorded on Fitbit won't show on MFP as a distinct exercise event. It will just be included in the information Fitbit normally sends - total steps and calories burned for the day.

    However, it is correct that an activity recorded in MFP will overwrite the data recorded by Fitbit for the same period.

    Thanks! Wasn't sure on that one... Usually I'm syncing activities in from other apps like Endomondo, and I couldn't recall what adding an exercise into Fitbit.com manually would do. :)

    Re: my other posts, above, after a pretty typical work-day wearing the Charge HR a bit more tightly, my HR measurements have been more like what I'd expect (50-85 BPM, rather than 50-120 BPM), and the spot checks that I've done with Azumio are matching up. The calorie burn estimates that are syncing over to MFP are now about on par with what I was getting from the Flex as well.

    I love having the HR data, but after about 4 months I'm starting to understand the drawbacks. I've also had it give me readings that were too high when I wasn't wearing it in a "regulation" fashion, resulting in calorie burns that were also too high. I think it was harder to confuse my old One (although it registered some unexpected "very active" minutes when I accidentally left in a pocket and put it in the wash).

    Now that I seem to have the HR measurements dialed in as far as the band tightness goes, it's been pretty consistent for me.

    With that said, I do think Fitbit's calorie adjustments based on HR could use some adjustment. It's not clear to me that they're appropriately cross-referencing HR with activity intensity... An elevated HR alone is not going to increase calorie burn as much as elevated HR combined with more intense movement, and I don't see much difference between calorie burn estimates for those two scenarios on my dashbaord.

    Looking at daily 5 min graph of calorie burn - you actually see increased calorie burn during times of minor increased HR but no increased steps?

    I had others, awhile back now so perhaps it changed, confirm that it appears step-based calorie burn was used up until a certain point, and then HR-based was used.

    Some people hyper-ventilated for me and got a HR increase while standing still - calorie burn was normal BMR level as sleeping or sitting.

    Feel like passing out? ;-)

    Honestly, it's a little hard for me to tell because of the crappy way Fitbit presents the data. Different charts and different implementations of the charts, depending on wich tile I'm looking at on the dashboard or which screen on the iPhone, and they don't let me export detailed HRM data.

    But, when I mouse over the HR data points on the dashboard tile, those at a higher HR tend to show a higher per-minute calorie burn, even during periods that I know I was relatively less active.

    Certainly not a scientific cross-reference but, until Fitbit grants me partner access to the API, I can't really pull the incremental data points to do a better analysis.

    Did you try going under Settings, data export, and selecting body for the time frame you want? Or are you after something more detailed?

    I would also skip the dashboard and go to the Log - Activities tab, where it's all laid out in 5 min increments. Better than the 15 min the dashboard gives, and much wider viewing area.

    I'm guessing you'll still have to back and forth between steps and HR and calorie burn to see if what you saw on Dashboard appears correct with easier view.

    That's actually part of the problem... There is no HRM data available on the Log tabs. But yeah, that was the data that I was looking at, except for HR, which i have to pull off the dashboard tile.

    I actually emailed Fitbit support to see if they planned on adding HRM data to the "Log - Heart" page but, in their typical fashion, they gave me two canned replies and then failed to answer me. :)

    Oh good grief. Another example of it not really being for the purpose of exercise, especially if you can't view that per minute or better logging of HR right then.
    That's the great way to tell if intervals are timed right, looking at HR differences between the peaks. And since that could be within 2 minutes, even the 5 min graph is useless - if it showed it.

    Yeah, they've got a long way to go to make it a serious tool, and I'm really surprised at the lagging functionality given the supposed focus of the Surge.

    Even the default API access doesn't provide granular data. You have to specifically request "partner access", and you have to promise to use the data for personal purposes only. If you want to create an app that's going to access the API then there are additional requirements (although I'm not sure what they are or if fees might be involved to cover bandwidth costs).

    See: https://wiki.fitbit.com/display/API/Fitbit+Partner+API

    ETA: Partner API does allow 1-minute granularity at least... Most of the general public isn't going to know how to use the API though.
