Dr. Oz is a quack. There, I said it.
It is all going to depend on your frame, really. I have a large frame and for my 5'4" self, I have a goal of 145. That is the size I was in law school and I was tight and athletic. My BFF is a little taller at 5'6", but at 145 she looks a little chubby. She has a small frame and would probably, ideally, be no more than 130.
