If your daughter likes pasta, then serve 100% whole wheat pasta with plenty of a veggie-packed marinara sauce and a sprinkling of a good fresh parmesan. The fresh cheese has a much more robust flavor than
Get rid of anything "starchy" that isn't 100% whole wheat - read labels! No potatoes, no white bread, no white flour. Triscuits are a nice snack and relatively low in fat and calories with a lot of fiber. Fiber is filling! Have her try taking a fiber supplement about 20 minutes before eating a meal, and she may find she gets fuller on less food.
Instead of red meat serve plenty of fish and chicken. Beans and eggs are a good (cheap!) source of lower fat protein. Also low fat dairy usually tastes better than fat free and generally has similar calorie counts and less fillers.
I have a mini trampoline that I bought about a year ago. I actually have some trampoline workout DVDs that are gathering dust on the shelf (the Urban Rebounding series). It can be a good cardio workout and helps build leg muscles too. Just have your daughter start SLOW - maybe 10-15 minutes of vigorous bouncing will be enough to work up a sweat and raise the heart rate without cauing too much muscle soreness.
Thanks for all the wonderful ideas. I'm going to get to work on a meal plan this weekend and try to set out menus for the coming week. I'm also taking her roller skating (her favorite aside from swimming) and she's experessed an interest in learning to ski, so I think she's on her way to better health--and a better body.
