You cannot lose 20 pounds in one hour by any natural means.
The most you can lose safely is 3 pounds per week, and then only if you are exercising enough to get your heart rate up for 30 minutes to an hour.
Excersie
i weight 150 i need to lose 20 lbs
Attempting to lose 10 pounds in one week is absurd. You'd have to be on the ab circle 20 hours a day.
yes, of course... im 5'2 and 103 pounds :D
Here is one of the diets you can do to lose weight http://www.fourhourworkweek.com/blog/2007/04/06/how-to-lose-20-lbs-of-fat-in-30-days-without-doing-any-exercise/
Yes.......... It depends on how active u r
I doubt it.. maby about 20 lbs if you tired alot
well you don't eat calories to lose weight, you lose them. you have to lose 3,500 calories to lose one pound so i'd say it will take like a year. but if you just eat healthy things with hardly any calories and exercise it will be easier.
Drink as much water as u can at least 20 water bottles in 3 hour
In the clinical trials, Meridia typically did not lead to weight losses as large as 20 lbs.
There are 20 minutes in one third of an hour.
