How to lose 50 lbs in 6 months? Any tips?

Hi, I appreciate any advice or suggestions you may have. I'm currently 5'4" and 178lbs, size 16. I've got a lot of work to do. I'd like to be around a size 6 by the beginning of the year but I know it's going to take a lot of hard work and dedication. Thanks in advice for any ideas you may have!
