How much weight could i lose in 2 weeks?

Hey =].
Before I ask anything, I just want to make it clear, I dont want any rude or horrible comments. Please.

I am a UK size 8/10, I am 14 years old and I weigh around 130Ibs (9stone 5Ibs).
I really want to become size 4 as soon as I can.
How much...

weight do I need to loose to achieve this, and how long will it take?
Lets say, for two weeks, I stuck to eating an apple (60 calories) every morning and a bowl of salad (50 calories) or steamed vegetables like carrots, peas and brocoli (80 calories) for my dinner. Did 1 hour of walking and 50 situps everymorning, and another 3 hours walking during the day. How much would I loose in the 2 weeks? Or have you got something better for me to try out?
Thanks for your time =]
