join a gym and go lots and lots
Just eat one meal per day.
If you burn 500 more calories than you eat every day for a week, you should lose about 1-2 pounds. If you want to lose weight faster, you'll need to eat less and exercise more.
Exercise at least 30 minutes a day while maintaining a balanced diet. Doing it this way will require time though, so don't expect to lose 20lbs in one week. But, you will definitely lose weight if you maintain this plan.
Unless you get gastric bypass you can't lose that much in one week. Even if you starve yourself.
While a diet plan and losing weight is good, I would not recommend trying to lose weight that fast. 20 lbs in 1 month is really fast and you shouldn't try to lose more weight than 2 lbs a week.
Not going to happen. Weight loss is not magic, it is eating fewer calories than you burn. With exercise and a sensible diet, you can lose about 2 pounds a week. That is 8 pounds in a month, not 20. If you try starvation, you will lose weigh more slowly.
