Is she having anything with sugar alcohols or sweets at all? If it is low blood sugar, then eating freuqent smaller meals, all about equal in carbs can help. She should also try having a light snack before bed, and maybe having something near the bed for when she first wakes up. A piece of string cheese, or later maybe just a couple nuts. Tell her to be careful not to skip meals, and to make sure to eat breakfast soon after rising.

Is she still having low fat out of habit? This could be contributing to her hunger pains. What do her typical menus look like?

Also with only 15 pounds to lose, and the fact they are only vanity pounds, she may not need induction and will lose slower. Instead why not tell her to look into Atkins for life. It starts off at a higher level of good carbs and is more of premaintanance. It will also take adding in exercise to tone up and get the look she wants.
