Following UFC 177, an event which had headliner Renan Barao yanked from his title bout following a difficult weight cut, UFC President Dana White was asked whether this is “a sign that the UFC can or should do anything to get involved in this process” referring to rapid extreme weight loss (“REWL”) practices which are the norm in MMA, to which White responded “Nobody’s ever been hurt from it, I mean, there’s only so much we can do“.
This reminds me of Senator Moynihan’s famous quote “Everyone is entitled to his own opinion, but not to his own facts.”

I was the ref.I taped his hands, because he was cornered by his brother, and neither knew how to wrap. I spoke with him some, to settle his nerves, and learned he was a first-time fighter, and a little older, with a background in traditional martial arts.In the second round something wasn’t right, so I stopped it. There wasn’t much protest. Then he passed out in the locker room. Then his heart stopped in the ambulance. He was airlifted to Boston, where he was diagnosed with renal failure.Day after day, I sought word on his condition; eventually his kidneys started on their own, so he didn’t need to be on dialysis for the rest of his life.The cause was a combination of the Atkins diet, then water weight cutting, and then heavy exertion under TV lights.“
