Fighting sports are graded according to weight. Losing weight can reduce one level to participate in the competition, and it has great advantages to compete with players younger than yourself.

Losing weight does not affect physical strength, but determines the skill, speed, strength and will quality of the players, and there is no causal relationship.

Some players lost the competition, which was attributed to physical exhaustion caused by losing weight. This is sheer nonsense and amateurish, deceiving public opinion and fans.
