Cutting weight is one of the most controversial topics in the sport of MMA.
Almost every fighter cuts weight in order to at minimum fight other people that are their own size, and at maximum have a height and size advantage over a smaller opponent.
Some fighters will cut a minimum amount of weight (5-10 lbs), but there are also other fighters who will cut a massive amount of weight (35 lbs) to fight at a weight class.
