    Most don't like BMI because it doesn't account for muscle. According to BMI, many professional athletes are overweight or even obese. Your best bet is to focus on a healthy body fat percentage (for women, 20% is ideal for athletes, other 25% is a great, healthy goal). I've also heard some people say that anything under a size 14 is healthy, but I'm not sure of the accuracy of that

    BMI is a general guide, if you have actively built muscle mass then it is not a good guide it shows a healthly range to aim for no more no less.

    I agree with sweetheart in that body fat percentage is probably the best way to go. However, if you do have access to a means of measuring this along your journey, I think it's fine to use BMI as a guide. Besides I imagine it's pretty difficult to predict the weight you will be with a given body fat, especially for a novice. You can always change your goal weight as you get closer and you see how your body looks and feels.

    I question the last part ( < size 14 = healthy). I'm just moving into a size 12 and my weight puts me on the border of "overweight" / "obese" BMI. I realize BMI is far from exact, but I think that for a non-athlete - it should be at least somewhat in range.
