Your starting weight might be a bit low, but why not give it a try and see how you do. You are about my height and weight, and that is about where I am now. But, I am 50, in menopause and have a sedentary job. I started with higher calories and have slowly worked my way down.
A couple thoughts. Add a multivitamin to insure that you are getting your nutrients. I love using Fitday to journal everything. It really helps me stay on track
