Wasnt trying to argue with you about it, I just simply said that I dont think it would be a great idea for someone/anyone to cut that much weight. It is difficult to regain all your power and strength after losing that much water. I have never cut weight, but Ive been dehydrated as hell, and even after IV and electrolyte ingestion, I feel sluggish.
Those with high school and collegiate wrestling backgrounds are at a distinct advantage when it comes to being able to compete after cutting.
Again though, the only thing a guy can drop in 24-48 hours is water, so when a fighter can't make weight but doesn't appear to be ripped, it's usually like you said, they're completely dehydrated -- but still holding fat.
