Hi.
I know I can do this, I just need a few numbers to get started.
I just read a thread on TDEE and BMR, but according to my calculations, my caloric intake seems too low (under 1200). I must be doing something incorrectly. Anyone able to give me a quick hand?

Age: 40
Woman
Height: 5'10"
Weight: 200lbs
Fat: 44%

Thanks in advance!
