How can I lose about 15 pounds and some inches in like 3 weeks?

I am 5'9 and I want to lose about 15 pounds so I can fit better in my clothes for camp coming up in about 3 weeks. Like what can I do? not eat much, do lots of floor exercises? I need help cause I really want to lose it before so I also look better in all the pictures I want to take there too! I would appreciate any addvice

again, its the same problem of all of us , we always forget that we need to lose weight till we face a crisis!!!
so, we are the(crisis people) need to face the problem from its begining than stressing on ourselves.
any way, i beleive that crisis people are like the person who walks safely, ignoring any bad thing which could appear on his way , but suddenly he found that there is a thief is running after him!!
what should i do?!!
of course i should run as much as i can away from him , i don't need of course to reach my home , at least i need to reach somewhere where i can feel safe & satisfied then i can continue my way to my home safely.
i mean, u were living simply accepting ur extra fat till u get that occaision which resemples the thief , u need to reach the maximal level of losing weight but it of course shouldn't be the ideal one as u can resume losing it after the end of ur occasion & it ll be much easier .
so, i ll give u my program just keep on it for at least 2 successive weeks, u ll notice the difference.
1) stop eating bread, rice, macarini, fast food, fatty food, sweets.
2)replace them by vegetables & fruits
3)drink as much as u can of water.
4)dance!!!!
don't run , don't have aerobics just dance , for me i tried the eastern oriental dance, its amazing .
dance for 1_3 hours /day , i guarantee for u losing about 750_1000 grams of course with the diet ,
its amazing that it makes u don't feel the time when passes while u r dancing , u just like who shoots 2 birds with one stone, losing weight & having fun!!!
