Opinions wanted :). I want to start body recomping so I'm trying to stream line my diet and I was just curious on thoughts of using daily fitbit calories to calculate TDEE. I had a In-body scan done and according to my bone/muscle/fat weight my BMR is 1624. Now I need to figure my TDEE. There is so much info out there to figure your TDEE and it varies so much that its confusing. My fitbit runs anywhere between 2300-3000 depending on exercise done that day. MFP puts me well below my BMR, around 1350 for 1 lbs/week. That just seems to low.

    The 1350 that MFP gives you doesn't include any exercise, or any activity over and above your chosen activity level.

    So if you're more active than the level you've chosen over the course of your work/home/school life and don't include exercise, then it will of course seem low.

    TDEE is approximately (bear in mind this includes exercise whereas MFP's Neat Method doesn't):

    Sedentary: BMR x 1.2
    Light Exercise: BMR x 1.4
    Moderate Exercise: BMR x 1.6
    Heavy Exercise: BMR x 1.75


    MFP, calculates as follows:

    If you don't know your maintenance calories (TDEE) you need to figure that out, either by paying close attention to your Fitbit's accuracy or by using this site and keeping close tabs - or both.

    It takes time, but it takes some method you trust as far as calories. It usually takes a few months of data to dial in - so, off you go! Research using your own data that you have or start fresh.
