Effective and fast ways to lose weight?

Bubbles asked:


I am trying to lose at least 20-30 pounds fast, although that may not be as possible as I would like it to be. So at least effective ways on losing weight would be great!!! I am currently taking Hydroxycut, so if anyone has any information on that as well, that would be great as well. But my main thing is an effective and/or fast way to lose 20-30 pounds.
I am mostly aiming for my belly fat, but also am trying to tone my thighs and calves.
