Not in a healthy manner, that's a pound a day! You didn't gain it in two weeks, don't expect to lose it in two weeks. A healthy diet and exercise is the safest route and should allow you to lose about 5 pounds in that time. You'd be amazed at how much of a difference that will make.

To lose weight, you need to diet and exercise. The amount of weight you would lose would depend on many factors, such how how long / how instense you worked out, what types of exercsie you do, the calories you ate, how much you slept, and so on. In two weeks, you can lose up to 5 or 10 lbs. with good workouts, cutting out bad / fatty / unhealthy foods, and eating more healthily.
It is probably not safe to try and lose that much weight in so short a time. You can't gain it that fast, don't expect to lose it that fast. Eat sensibly and exercise. Ten pounds the first two weeks of a life style change is possible, but difficult.
