And just how would you do that? Say a guy comes in five pounds lighter in the weigh-in, and you challenge him on it. You know what he's going to say? "Oh, I had just used the bathroom, and I was so busy with media obligations that I forgot to eat anything." What are you going to do, call him a liar? Hire a guy to follow him around and write down every time he picks up a sandwich or uses the bathroom?
It's just not logical or feasible to ban weight cutting altogether, since weight fluctuations happen naturally. The best you can do is set a percentage limit, which, AFAIK, is what the UFC has already done.
LOL
sorry, ubt your example is just too stupid.
ONE banned weight cutting. Go check how they did it.
You will see that it is not so hard to do.
Wrestling, if I am not mistaken, also took steps to not allow wrestlers to do extreme cutting (after a wrestler died). Check it out how they did it.
DO you rather wait for a fighter to actually die before thinking about it without being an idiot doing so?
Hint: It has NOTHING to do with bathrooms.
It has to do with how hydrated fighter are while weighing them, and continuously weighting fighters (hint: they can't keep dehydrated for too long).
Much like the athlete's biological passport is helping against PED's, something similar can help against weight cutting.
If there ever was interest in banning weight cutting, they would have done it. easily.
But fighters don't want it (despite how detrimental to their own health this is), and the UFC doesn't want it (so they wouldn't be able to do all those champion moving weight and challenging the champion above/below).
And THAT is why we don't have it.
Pure unadulterated Greed.
This has NOTHING to do with science or inability to create a system that would support it.
