Obviously not 20 lbs.of fat. 20 lbs. of WEIGHT, mostly water, that depends on how fat you are now. But lets just do math. If you ate nothing, you would probably create a calorie deficit of about 2000 a day. This means in 21 days you would use 42,000 calories. 3500 calories make up one lb. of fat. So you would in theory lose 12 lbs. of fat. That is, if your body was a machine, which it's not. I'm just making the point that even the math doesn't work. So in addition to eating literally nothing, you would have to burn an additional 1400 calories a day from exercise. Of course if you actally tried this your body would crash hard, and you might do metabolic damage since you would literally be starving yourself. You wouldn't have the energy to exercise at all. And you might possibly kill yourself in the process (not joking). If you approached it in the most aggressive, but smart, way possible, the average person can lose about 4 lbs. of fat in a week. But that type of diet is brutal. You might be able to push such a thing for three weeks. In which case you might lose 12 lbs., but probably a little less than that. Such a diet is also no carb so you'll dump a lot of water weight, which might, if coupled with a dehydrating strategy at the end, get you down 20 lbs. but it would be half water. Unless you are REALLY obese, then you can drop significant amounts of fat and water safely and quickly. Think 350 lb. Biggest Loser contestants.

With extreme dieting and exercising, then yes, it is possible. It is also possible that you will gain it all back afterwards. That is also unhealthy. If you put the work in to keep it off, then at some level it will be worth it. Have fun with that :D
