How much protein should I eat?

Katiedid717

I've read in several places that you should eat 1 gram of protein for each pound of your lean body weight. My LBW is approximately 118 lbs/53 kg, but MFP only has me eating 45 grams of protein per day. Any clue which I should be aiming for?

For reference, I am 5'7"/170 cm tall and I weigh 194 pounds/88 kilograms. I used this calculator to get my LBW: http://easycalculation.com/medical/lean-body-weight.php
