I dropped 22 pounds in one week. We lost in the 3rd round of the football playoffs and my first wrestling dual was the following Thursday. I dropped from 190 to 168 to wrestle a state champ who obliged me by whipping me 21-0, this was before techfalls were a thing. He wasn't THAT much better than I was, but after starving myself for a week I was as weak as a kitten and he just tossed me around like a gorilla does a suitcase. It took me a couple weeks to get back to feeling decent again, pulling big weight sucks balls.
