Hey guys! I've got a question for those of you who are using Fitbit along with MFP and have it synced. I realize that Once you link the two together, fitbit will adjust the amount of calories you burned and put it on MFP as exercise. With that, does that mean we should not log our exercise already because Fitbit is doing that for us? I don't want to say I burned more calories than I actually did. I put in the time where I worked out, and duration on MFP, and it just seemed to add that on to what Fitbit adjusted onto MFP as well. Should I just not track my exercise then and let the app do all the work?

I am also thinking of buying an HRM to get a more accurate look at how many calories I'm burning as these sort of things take into consideration height and weight and not your overall mass, or heartrate. Still trying to find the best and accurate way of tracking this. Anyone have any suggestions?

    Any suggestions could help. Wondering if I should get the HRM as well, or if that would interfere.

    I don't have a Fitbit, but I understand from reading other posts that if your workout is step-based (ie. running/walking) then you might be fine with letting Fitbit calculate the numbers. However, if you are using some other way to calculate, such as with a heart rate monitor, then the best thing to do is to go onto the Fitbit dashboard, and replace the time period of your workout with the numbers from your heart rate monitor. If you do it on the Fitbit dashboard instead of MFP, then you won't be counting that period of time twice.

    Someone with Fitbit experience is welcome to come along and correct if I've misunderstood.

    Oh I see, I think that would help a lot. I really just didn't want it to double the calories from my workout to make me believe I burned way more than I did.

    I just got the Fitbit Charge HR, which has a heart rate monitor built in, and it's great. I've only had it a few days, but it seems pretty accurate. You press the button when you start your workout, and again when you finish, and it automatically calculates calories burned and sends the info to MFP. So clever!

    Once you link your fitbit to MFP when you enter cardio on MFP it asks you the time in addition to the duration; it then automatically removes tracked activity by the fitbit in that period. If you're walking or running you probably don't need to bother; but anything else you'll log as normal and MFP/FB will work it out for you. You don't actually need to log anything on fitbit (and it's much less confusing that way) because of the automatic syncing.

    I just started using my Fitbit flex with MFP and it specifically told me NOT to add my calories to the fitbit system, but add them to MFP. What happens when they sync then is they compare the two and if the fitbit indicates more calories burned than what I input it gives me additional calories. For instance, I walked on the treadmill for 95 minutes and entered the exercise on MFP. When my fitbit later synced, the fitbit indicated I burned two hundred more calories than I indicated I did, so MFP adjusted for that.

    If your exercise is step based, do not log it on MFP. If it is not step based, log it on MFP.

    thank you everyone for the input. I think I was just a little curious on how things go, I appreciate the feed back.

    I've had a fitbit One for 3 years now. I log my exercise calories (as determined by my HRM) separately, and I do it in the fitbit app. When you do that, the calories that are determined by your fitbit for that period of time are overridden.

    You can log it on either side, the calories will still be overridden for that time period.

    I've been using a fitbit for 9 months and I use it for all of my step-based activities. The only time I log anything separately is if I swim, or if I've forgotten my fitbit at home. So far I feel its doing a pretty good job. I weigh my food and log meticulously. I'm losing at the rate projected with the deficit given me by mfp after fitbit's adjustment, so I feel as though its accurate enough for me without switching to a heart rate monitor. I think it underestimated activities like Zumba, but I only did that once per week and a hundred calories or so weren't going to leave me starving.

    I log ALL exercise (even the non-step-based type, which is manually added) in Fitbit and ALL food/beverages in MFP. They talk to each other. Seems to work fine.

    I am using a Fitbit for over a year now. It ONLY tracks steps so I allow it to track my steps but I log my spin classes and yoga, exercise bike because Fitbit does not track those.

    You bought the FitBit to make your activity calculations for you so I'd leave it to it rather than mixing and matching calculations if I were you. I only enter swimming and aqua aerobics separately now but use the burn rate FitBit would have given me had I logged it there but actually log in in here so my friends know I'm keeping busy!

    For gym cardio sessions (bike/treadmill/cross trainer) I've found my FitBit One pretty much bang on against the burn rate the Precor machines are giving me (across the session) so only bother with my HRM if I'm having a bash at interval training. My Polar readings for calorie burn can be a bit wayward.

    Here's a link to the FitBit group. You can find your particular model and get a feel for what others are doing.

    I have a FitBit One......my cardio is step based, so I don't bother recording cardio. I have a heart rate monitor (from years ago) and basically don't use it. HRM's are only designed for steady state cardio....not other forms of exercise (anyway).

    I didn't sync Fitbit with MFP.

    If you do, don't log exercise on MFP, as you will be double counting your exercise.

    I got the Fitbit to make me walk more (I have a desk job), and MFP to track calories.

    Lastly, make sure you set the activity level in mfp to sedentary. That way any exercise that the Fitbit logs will be your only exercise and therefore any exercise calories will only be counted once.

    If you set your activity level to something higher it will automatically give you a higher calorie allocation which will throw things off balance.
