20 lbs divided by 3 equals 6.2 pounds a week...gee, i don't exactly know how you are going to do it????you could try starving yourself by just eating a piece of fruit for breakfast and a piece of fruit at lunch along with some milk...then a fruit at dinner along with water...because fruit is all water anyway...maybe you might feel OK, BUT i do not know,,,,,Never tried it!! good luck!! Ice Tea is good also...no calories....

run 8 miles a day, 6 days a week. 4 morn, 4 evening.... thatll do it for sure, only prob is not many (even very fit people) can do that.
Running at least 20 mins a day 4-6 days a week, u'll lose about 5-8 pounds first week. And about 10 pounds total in 3 weeks, as long as you keep a strict diet.

even if you starve yourself and run 10 miles every day...theres no way possible for you to lose that much weight in 3 weeks. if you do the most unhealthy thing (not eating and exercising excessively every single day) you might be lucky to lose 12 to 15 lbs in 3 weeks....but 20 is impossible. serously. unless you get lipo.

You can only lose 10 pounds in a month. Its impossible to lose more than that in one month. By the way you will gain twice the amount if you diet unhealthy.

I really do not think it is possible. maybe in 8 weeks or so but 3 weeks is pushing it.

Chops your legs off, or you can become belimiac, or you could get plastic surgery, that could take a while though.

Other than chopping off a body part there is no way.
