I know this is going to sound harsh, but stop daydreaming and embrace the reality. Did you really gain the 20 pounds in 1 week, of course not so you cannot lose the 20 pounds in 1 week either! Period! But stay with me for one second please.

It is impossible to lose 20 pounds in just one week. But you can lose the 20 pounds in about 2 months. Now you are going to say, yes I can I will exercise like crazy and not eat...Good luck with that. You are heading toward unhealthy life. No matter how much you exercise and even if you don't eat anything the whole week you will not be able to lose all those pounds. Simple fact is, it is physically impossible.

A lot of people when making their own weight loss plan, set a goal to lose 10 to 20 pounds per week. Now they believe that this is possible due to one single fact that your body does lose one to two pounds the first day. However, it is not your body fat that you are losing. Those are just toxins and some additional water that your body doesn't need any more. To burn calories and all that body fat you need a lot more time and a lot more muscle.

One that is responsible in distributing how many calories you can burn a day is your metabolism. Now, you can speed up your metabolism and it still can never work that fast in order for you to lose weight over night. I am certain that it took a lot longer for you to gain fat, at least for some six month. And now you believe that you can actually do something to lose it twice faster then it took you to gain all that weight. Not to mention how unhealthy that would be and what kind of shock you would put your body through.

Imagine what would happen to your health if you were to lose 20 pounds in a week, in such an unhealthy way. I have to emphasize that there is no way that you can lose all these pounds in a normal healthy diet, and why would you want to undergo anything that is not safe and effective. All taken into the account your health is a lot more important, and if it means that it will take you at least a month or two to achieve that goal, so be it.

There is also one more trick why this kind of weight loss is impossible and unhealthy. If you achieve in speeding up your metabolism a little by exercising, the first days it will be burning calories in a great amount. But what happens later, when it slows down, because of small amount of food that you take. Your metabolism needs food to speed up, and by starving there is no way your metabolism will be able to work that fast. So that is when the troubles come. After few days, you will feel exhaustion; you will be so hungry, that sooner or later you will start imagining food. You will lose concentration, and not to mention how nervous and irritated you are going to be. Therefore, the only thing that you will achieve is to feel more hunger then ever. Eventually you will give in because you will not achieve the wanted result. With one difference only, now after this torture you will eat more in order to make up for all those days that you were hungry. So there is just no way you can lose 20 pounds in a week.
