Ok....so my wonderful husband got me the BEST Christmas present ever....a BodyMedia!!!! This arm band is awesome and I barely know it's there!!! It tracks my sleep (definitely don't get enough in quantity or quality), my steps and my calories burned.

I'm calculated my BMR, TDEE, etc. before using all the calculators but decided to see what my TDEE is with the arm band. This is for the last 14 days, NO EXERCISE (family situations have prevented this) and is the average of calories burned in the 14 day period.

So the average is 2300 ish (just a smidge more but I'm rounding). So I think this is my TDEE.
My BMR (per fitness frog calculator) is 1559.
20% below my TDEE (which is what I figured) is 1840.

Now this is all with no extra exercise and only what I do during the day (I work in a middle school as a counselor so I walk A LOT around my building).

So, from my research, I'm supposed to be eating at 1840 to lose weight. Right?
If I add any exercise to this do I eat back those calories to NET 1840 or not?

Between finding out my dad is sick (stress eating) and the holidays I gained 15 lbs. Before that I was going on a whole year of not losing any weight pretty much no matter what I did. So I'm trying to come up with what will work so that I can lose this added weight and hopefully 20#s more!!! Please let me know if I'm on the right track and if I'm doing this right!!!

    If your BMR is 1559 at a sedentary activity level of 1.2 your TDEE is 1871. 20% cut from 1871 is 1497 which is below your BMR. Eating at 1871 you would just be maintaining at a sedentary level. However, few people are sedentary. An inbetween number of sedentary and lightly active is 1.35 which would boost your TDEE to 2105. A 15% cut from that is 1789. That is a deficit of 316 calories per day or a little less than a pound a week. 20% is 1684 or a deficit of 421 which is nearly a pound a week. So, it all depends upon your activity level. If you do more than lightly active eat more.

    However, if you trust your Body Media's TDEE at an average of 2300 calories that is an activity factor of 1.5 which sounds ok. 20% of 2300 is 1840 or a deficit of 460 which is about a 1 pound loss per week.

    I used the BMR on Fitness Frog and they didn't ask for activity level. The TDEE calculators for lightly active puts me around 2100 calories and for moderately active puts me around 2400. I've used my Body Media for 3 weeks now but the last 2 weeks has been mostly representative of my lifestyle because I've been back to work. The average over the 2 weeks of my calories burned for the day is rounded down to 2300 calories for the day. I do walk a lot at my job but that kind of blows my mind since I've been unable to do any extra exercise!!

    So it looks like my calculations might be correct. Now when I'm able to exercise what do I do with that? Do I eat my exercise calories back or not? I'm really trying to break a 1 year plateau!!!

    Anyone?!?!

    Will you wear your BodyMedia when you exercise?
    Then the TDEE will go up, then the 20% deficit will go up.

    Is it walking or jogging the BMF will be semi-accurate with, or an activity that is totally off so you'll remove the BMF and wear a HRM?
    In which case eat back your exercise once you subtract the same deficit off it, 20% it appears.
