I just started tracking everything I eat on fitday and I had a quick question. So far all the foods they have listed seem pretty accurate, but my question is about the calories burned section. I'm a big guy (280lbs) and it is saying that having a seat job with some movement I will burn over 4000 calories a day. Does this seem right? It just seems a little high to me. Thanks in advance to anyone that can shed some light on this for me.
