I dont think its possible to lose that much in a week in a healthy way...

If you are a very overweight person you can lose two pounds very quickly, and depending on how large you are 20 in a week is possible. But, still not a very good idea. The people on that show (which I have only seen previews) work out almost all day long doing things most thin people don't even do and they only eat what they are given. It is a lot easier to be that disciplined when you don't have a choice.
If you really want to lose weight talk to your doctor. Cut your calories back to what your doc recommends and start working out often. You will lose weight. But, just remember, the smaller you are the harder it is to lose weight. The heavier you are, the easier it is to lose.

I'm starting to think 20 lbs. In a week, is not only possible, but incredibly easy if you weigh around 200 lbs or more!

Read my blog if you want more info. I'm not advertising or selling anything, just posting what i'm doing (no product plugs or anything like that), and the results as they come. I also welcome comments, suggestions, all that.

So waht do this shakes do end the hunger or something?

Meal replacement shakes are shakes that taste almost as good as a real milk shake (they are tasty enough that you will look forward to drinking them) and that primarily contain protein and have a balance of vitamins and nutrients. The shakes mix up nice and thick so they are very filling and do not leave you hungry like a rice cake would. So the short answer to your question is that meal replacement shakes are tasty, filling shakes that have all the vitamins and nutrients of a meal but only have 180-250 calories.

I honestly don't see how a person could lose 20 pounds in one week!!! That can not be healthy, people! Have you ever heard "the faster you lose, the faster you'll gain it back"? Reducing calories is your best bet, along with some major intense cardio or aerobics. That will blast the fat fast!!! If you reduce calories to around 1000/day, you will lose pretty fast. I know drs don't recommend you eat less than 1200/day, but trust me, I cut to 1000/day and lost 8 pounds in 17 days (and i'm a thin person). So, if you are overweight or obese & you're eating 1000 calories/day you will lose fast, fast, fast!!! Try it!

Lose 20 pounds in a week? Maybe with liposuction!
