How can I lose 20 pounds FAST?

im wanting to join the airforce, but i need to lose almost 20 pounds! how long do you think it will take me?
If you lose about 3.5 lbs a week you should lose 20lbs in about 6 weeks. Make sure you do a lot of cardio and eat healthy (lots of protein!) and you will be fine!

Seriously, I would take fat burners. They aren't very safe though. Almost like speed. GNC has em.

hmm thats ALOT of weight so id say about 2 weeks. DONT starve yourself because if u do once you lose the weight you'll just put it back on fasttt enough. so what i'd say is make a workout plan for yourself. workout EVERYDAY. drink lots of green tea or oolong tea. cut back carbs and fats…
good luck!
