If you're only looking to lose the weight temporarily, then starve yourself. However, if you want to lose it and keep it off, exercise is the best way.

Drink a lot of water and only eat one really small very healthy meal a day. Of oucrse this is very unhealthy to do and you will probably gain the weight back once you start eating again.
