Sorry sawheet...but I have to disagree w/ you on this one!
You're talking to a 17 year old girl who's not even eating enough food as it is! And you're telling her to cut out half of what she is eating. While I agree w/ all your suggested food replacements, I'd rather see her eat ENOUGH food in the first place!
Tyger, here's a list of some good foods you should try to incorporate into your diet. DO NOT CUT YOUR CALORIES! You are not eating enough food as it is. If you want to lose bodyfat and gain a little muscle, you will harden up your physique simply by eating enough of the right foods and lifting weights. I will work on a bodyweight program for you and post it a little later...is it possible for you to get some dumbells or exercise bands at all?
I see no reason for you to cut yogurt and fruit at the moment...yes, maybe later down the road in a couple weeks you could cut them out when you get used to eating better.
