Mate, 15% on a girl is equivalent to about 10% on a guy. Not to cast aspertions(sp) but I suspect she's that low and wants to be leaner. But I may be wrong.

Plan looks pretty good though I'd probably move the carbs from meal 3 to post workout and put some veggies in meal 3 too.
And something is amiss with the fats - you total 56g but there is only 28g or so if you add the meals up.

How much lifting/cardio is planned.
