In a podcast interview, renowned Brazilian jiu-jitsu black belt and historian Robert Drysdale proposed a controversial idea for maintaining standards in jiu-jitsu as the sport continues to grow rapidly – using body fat percentage as part of the criteria for black belt promotion.
Drysdale expressed concern that as jiu-jitsu becomes more commercialized and widespread, there is a risk of losing quality and credibility. He suggested that in addition to time-in-training requirements, academies could consider implementing body composition standards for belt promotions, particularly at the black belt level.
“I think you should measure body fat. I think that people that are like…if you’re too obese you should…you got to lose weight before you get promoted,” Drysdale stated. “That’s a good standard.”
He clarified that he was not trying to fat-shame anyone, but rather promote health and provide incentives for practitioners to maintain fitness. Drysdale argued that being healthy is better than being unhealthy, and that having some physical standards could help preserve the martial art’s values of discipline and self-improvement.
However, Drysdale acknowledged this idea would likely be controversial. When pressed on whether someone could still be highly skilled at jiu-jitsu while being overweight, he agreed that was possible.
Ultimately, Drysdale framed the suggestion as part of a broader conversation about how to maintain quality and standards in jiu-jitsu as it grows exponentially in popularity worldwide. While body composition may be one potential metric, he emphasized the importance of preserving the art’s core values and efficacy above all else.
The comments are likely to spark debate within the jiu-jitsu community about what criteria should be used for belt promotions and how to balance inclusivity with maintaining high technical standards. As a respected voice in the sport, Drysdale’s perspective adds an interesting dimension to ongoing discussions about jiu-jitsu’s evolution.
