16 and want to loose weight ,quickly as possible for prom?

Im 16, about 5.10 and i am over weight and i really want to flatten my stomach quickly as possible because prom is in about 3 weeks and i am going on holiday straight after. So please help because my date is skinner than me and I would love to impress her …..So what can you recommend so that i can loose weight from under 3 weeks?

I am afraid you are not going to alter your body shape in 3 weeks even if you do lose weight.

Do you see the box near the top of the page?
The one labelled ‘Search for questions: ‘?
Well type in ‘lose weight‘.
You will find over 15,000 preexisting questions.
Try the misspellings ‘loose weight’ and there are another 5,500.

On average these each yield 6 answers, that is over 300,000 answers.
