I've been trying to do that this year. Down 20kg since January so far. Aiming for another 10kg still though.
My method: Usually eat once a day (1 chicken breast, maybe 2 if I'm feeling greedy and sometimes an egg or 2 as well), occasionally more than 1 meal a day, and sometimes even none. Daily exercise. And finally drinking a lot of wine (I don't know why, but I usually seem to lose quite a bit of weight after a night of heavy drinking).
