Do you know how beneficial carrots are for you? They are the staple of a lot of detox programs (the juiced version).
Speaking of which, doing a 10 day detox might not be a bad idea for her. I've read that it can eliminate a lot of toxins and material that is literally stuck in the digestive track which otherwise might never come out.
Anyway, the weight number shouldn't be too important once she looks good. I think once a girl looks decent she can then just focus on trouble areas, or more toning and more definition. Just my .2.
