Hi Rez...
I can't help you with the calorie question, but geez...if you're 5'6" and only 107 pounds...i don't think you're in any danger of porking out. (i saw your beautiful photos!)
but i know that people telling you stuff like this just isn't that convincing--we all know our bodies best, and we know what feels best, and right, for us. i hope your back gets better quickly...it's hard when you're so used to working out and then your body "betrays" you.
hang in there...
