http://www.everydiet.org/diet/18-pounds-in-4-days This site gives you information on how you can lose 18 pounds in 4 days. However this is never a good idea to attempt and losing weight should be a longer process then four days for it to be healthy for you.
Eat healthy and exercise.

Short of radical surgery - you can't.

if you eat more smaller meals more often you can lose 2-4 pounds a day.

It is, but unless you are very overweight or overweight, this is not safe.
Why do you want to starve?It's just impossible!
No. However, if you drink a gallon of water, juice or soda in a short period of time and then weigh yourself, you will have gained 4 kg. Just about all of that will be excreted through the urine. So, in this kind of scenario, it would not be unusual to lose 4 kg in two days.
