Is it possible to lose 20 lbs in 6 weeks?

You can lose weight but not that much in 2 weeks. The only way to lose that much in such a short amount of time is to starve yourself which isn't good because you will gain weight instead of losing weight a Good way to lose weight fast is EXERCISE and DIET. Exercise everyday for about 30 minutes. Jump rope, run, and just other things like squats and push ups. Go on a diet too. Don't eat bread pasta candy chocolate and other junk like that. Don't eat sugar either. Try not to eat too much. If you have say 3 meals a day eat like 2 and an Apple or banana for a snack. Drink lots of water! Water will help a lot. Hope I helped(:
