Hello everyone
I have been using the fitbit for the last month with mfp and am really confused because am not losing any weight .
I am a 23 years old female . I have tested my bmr at the lab which was 1391 kcal .
I weight 74.9 kg, 169cm height ,36.9% bf and 25.9 kg of muscle .
how can I know what is the bmr that fitbit is setting for me and how can I change it in order to lose 1kg /week?
dose mfp takes the whole fibit kcal (bmr+activity) and add to that here ?

Any help in how should I set my goals here or there would be really great!
Thanks in advance!

    In Fitbit you just choose a food plan with easy/medium/hard wt loss and set goal etc. Sorry for brevity - at work! My Fitbit has been invaluable in maintaining or making small losses where needed and has been bang on for me.

    Have you linked your Fitbit account to MFP ? If so when you sync the fitbit your calories in MFP will adjust if Fitbit recorded activity higher than MFP was expecting. You'll see extra calories from exercise appear in your goal, without having to enter exercise into MFP.

    Did you set your MFP goal at 0.5 lbs/week loss ?

    No, I set it to "0.6kg /week " projected weight loss
    mfp set my calorie intake 1200kcal /day
    for example yesterday ,in mfp mobile App it says :
    *fitbit calories burned 2,581
    *mfp calories burn 1,913
    *fitbit calorie adjustmet 668
    I walked on treadmill yesterday and according to my polar HRM i burned 450 kcal
    so dose that mean I only burn 200 from daily activity ...
    anyway, I am trying to find out why my weight is not changing ,and since am not lifting nowadays (am sure not growing muscles here) ..

    If you had your BMR tested in a lab, that is likely to be the most accurate measurement, as opposed to both MFP and Fitbit, which are estimating based on the BMR of the average person with your stats.

    So assuming the lab results are the most accurate, your BMR is 1,391 cals. That means that you should be eating AT LEAST 1,391 calories every day to make sure that your organs function properly and you're meeting your nutrition requirements. Regardless of what MFP or Fitbit set as your calorie target, you should manually set it to something higher than 1,391. Start at 1,400 for simplicity.

    The fact that you are not losing weight is likely that you are eating more than you think you are. There's really no other explanation for why you would not lose, unless the lab results are completely wrong and your BMR is somewhere under 1,000 (which seems highly unlikely). Make sure you are logging everything you eat, including cream in your coffee, and measure everything you eat.

    The fitbit calorie adjustment is added to your MFP diary to correct for the difference between what MFP estimates and what your Fitbit calculates based on your daily movements. From what you posted, your Fitbit calculated that you burned 2,581 yesterday, which is a combination of the 450 cals burned on the treadmill and another 2,131 from daily activity (walking, breathing, existing). MFP had estimated that you burned 1,913 from all of these activities, so the 668 adjustment just brings the MFP total up to what Fitbit had calculated.

    This means that theoretically you would lose weight if you ate less than the 2,581 you burned yesterday.

    Sometimes it takes a long time to see results, since things like water retention, food mass in your intestines, etc. can throw off the scale. It's helpful to take measurements as you go so that you have more than one data point to track.

    If you consistently track your food and are truly eating less than you are burning but not seeing results, talk to your doctor or come back to the forum and open up your food diary so that people can provide more informed advice.
