SF, I use the standard FitDay calorie burn calculator, but I also make sure to add sleeping as an activity each day. When I add my sleeping hours I find that it's really pretty accurate. Try it...maybe it will work for you too.
Start (1/9/14): 276.8
Goal (Summer, 2015): 130ish
Next mini goal 238 by 10/17
17.8 lbs to go until next bigger goal.
Would like to be as close to ONEderland by Christmas as possible.
