IT is very confusing, and a lot of different answers depending on who you ask. The two golden rules are:

10 to 12 times your goal weight. (This is what you do not want to go under so your body stays out of starvation mode.)

OR 10 to 12 times your current weight. ( I personally think that if you are going to count calories, as long as you stay anywhere between those to numbers you will be fine.)

So you would want to stay any where between 1300 to 1600 calories. NOW more important! Listen to Lori! The fat ratio, try to stick around 70%! This is indeed more important than anything else. Atleast for the losing part of the program.
