There is no fast and quick way to lose weight. You didn't put it on overnight, and you won't get rid of it overnight either.
To lose weight, you need to eat less calories than you burn in a day, so working on your diet and doing some exercise should be your way to lose weight. If you could tell us a bit more about yourself (age, height, gender, what you eat, if you exercise etc.), then I'm sure you could get some suggestions.
