How to cut 20lbs in 5 days

I am fighting in Peru and Argentina in 2 weeks in the 81kgs/178lb weight category.  I usually walk around at 205lbs.  I haven't made this weight in a very long time. So I decided to do a mock weigh in before I head out there to compete. I made a video everyday as reference. I lost 20lbs in 5 days. Enjoy!!
