Make her starve herself and then sniff 10 foot rails of coke. That will do it.
Just kidding.
Seriously, though, my girlfriend eats a ton of sushi and whatnot, in addition to doing a cardio circuit four days a week, and the other three days she does weight training. She's 5'0", 95 lbs. She's lost 5 lbs. since she started doing that about 6 months ago. That might seem crazy for a girl that's already 100 lbs., but she's only 5'0", so any weight variances make a huge difference.
Let me state that I make a HUGE effort to avoid questions like, "Do I look fat, " etc. Any weight gain or loss that she has is all her own doing, and I make sure to have 0% to do with it. All I do is try to positively reinforce her efforts.
Nonetheless, my girlfriend took the natural/water approach. Anything that is naturally high in water and is not processed is good. That includes fresh vegetables, fruits, nuts, etc. Foods that are really light and fill you up fast. She eats about 8 times a day, or about once every hour.
