Dustin Poirier, the veteran UFC lightweight contender, has reignited a debate over size disparities in mixed martial arts after revealing that Islam Makhachev—then the reigning UFC lightweight champion—was significantly heavier during their title fight at UFC 302 in June 2024. Poirier, who weighed in at 176 pounds that night, estimated Makhachev tipped the scales at 190 to 192 pounds, a differential of 14 to 16 pounds that he described as ‘insane’ after reviewing official fight-night records. The revelation has sparked discussion about weight-class integrity, fighter safety, and the physical evolution of elite MMA athletes as they transition between divisions.
Why Size Matters in the UFC Lightweight Division: The Poirier vs. Makhachev Weight Revelation
The UFC lightweight division, historically defined by the 155-pound limit, has seen a dramatic shift in the physiques of its top contenders in recent years. Fighters like Islam Makhachev, Charles Oliveira, and Islam’s successor as champion, Islam Makhachev, have redefined what it means to compete at the highest level. Makhachev, a 5’11” Dagestani grappling specialist, has long been open about his struggles cutting to 155 pounds and has publicly stated his intention to move up to welterweight—a transition he completed in November 2024 when he defeated Jack Della Maddalena to win the UFC welterweight title.
Poirier, a former interim UFC lightweight champion known for his durability and volume-striking style, faced Makhachev in a high-stakes lightweight title bout at UFC 302. The fight, which earned both men Fight of the Night honors, ended in the fifth round via Makhachev’s signature brabo choke. But it was the size disparity revealed in post-fight discussions that has since dominated MMA discourse. Poirier, speaking on *The Joe Rogan Experience* podcast in early 2025, recalled staring across the octagon and immediately noticing Makhachev’s muscular build, visible veins, and overall presence.
“I looked across under those spotlights, and he had veins in his shoulders and shit. I’m like, f*ck, this guy’s huge.”
The moment stuck with Poirier long after the fight. It wasn’t just the intimidation factor—it was the realization that Makhachev’s size advantage may have played a pivotal role in the fight’s outcome. According to Poirier, UFC officials later confirmed Makhachev’s official fight-night weight was 192 pounds, while Poirier weighed in at 176. The 16-pound difference—nearly 9% of Poirier’s body weight—raises critical questions about whether the 155-pound division is becoming physically unsustainable for elite athletes.
The Role of Weight-Cutting Culture in MMA
MMA is uniquely punishing when it comes to weight-cutting. Fighters routinely shed 15 to 25 pounds in the days leading up to a fight, only to rehydrate immediately after the weigh-ins. This practice, while designed to maximize competitive balance within divisions, has long been criticized for its health risks, including kidney failure, heart strain, and cognitive impairment. Makhachev, like many top lightweights, has publicly discussed the toll of cutting to 155 pounds, calling it “brutal” and “not sustainable.”
By the time of UFC 302, Makhachev was already vocal about moving up to welterweight. His physique—broad shoulders, dense muscle mass, and a thick neck—was visibly larger than most of his divisional peers. Yet, under the UFC’s rules, he was still eligible to compete at 155 pounds because his official weight was taken after rehydration, not pre-fight dehydration. This system allows fighters to compete at a natural weight significantly above the divisional limit, potentially creating mismatches in size and strength.
Poirier’s Post-Fight Analysis: A Submission Like No Other
Poirier’s technical breakdown of Makhachev’s choke—known as the brabo choke—has also drawn attention from grapplers and fight analysts. Unlike traditional D’Arce or Anaconda chokes, Makhachev’s version is applied with his forearm parallel to the opponent’s neck, pulling toward his own chest rather than angling it downward. This creates a different pressure point, cutting off blood flow more abruptly and giving the victim less time to react.
“The way he did it… he locks it on his forearm. He doesn’t go to the bicep. The squeeze is different. He’s pulling to his chest. It’s not like an angle squeeze. So the defense is different.”
Poirier recounted that as soon as the choke locked in, he began to lose consciousness almost instantly. “You know how you usually feel it slowly fading away? It was like quick, right away. The darkness started coming in as soon as he got the grip.” The choke’s effectiveness, combined with Makhachev’s size advantage, made it nearly unstoppable that night—an experience Poirier has not forgotten.
Islam Makhachev Responds: Denying the Weight Discrepancy
In the wake of Poirier’s comments, Makhachev took to Telegram to refute the weight claim. “I’ve never weighed more than 80kg (176 pounds), ever,” he wrote in a direct message to fans and media. Makhachev’s denial is consistent with his long-standing public stance that he has never permanently moved above lightweight, despite his physical frame suggesting otherwise. His move to welterweight in late 2024 was framed as a strategic decision to compete at a more natural weight, not an admission of being oversized at 155.
Makhachev’s rebuttal underscores a broader tension in MMA: the disconnect between a fighter’s natural weight, their ability to make a division limit, and the UFC’s enforcement—or lack thereof—of weight-class standards. The promotion has no formal policy penalizing fighters for significant weight disparities on fight night, as long as they meet the official weigh-in requirement. This has led to debates about whether the UFC should consider natural weight when sanctioning title fights or limit the number of pounds a fighter can gain between weigh-ins and fight time.
The Broader Implications: Is the UFC Lightweight Division Becoming Too Big?
The Poirier-Makhachev weight debate is not isolated. Over the past five years, the average physical profile of UFC lightweights has increased dramatically. Fighters like Islam Makhachev (5’11”, ~185 lbs natural), Charles Oliveira (5’10”, ~190 lbs natural), and Beneil Dariush (5’11”, ~188 lbs natural) have redefined the division’s upper limits. Even former champions like Khabib Nurmagomedov (5’10”, ~185 lbs natural) were notably larger than traditional lightweights of the 2010s, such as Benson Henderson or Anthony Pettis.
This shift has led to calls for the UFC to either expand the lightweight division to 165 pounds or create a new super-lightweight class (160–165 lbs). Supporters of such a change argue that it would reduce the health risks associated with extreme weight-cutting while also preventing the kind of size mismatches seen in fights like Poirier vs. Makhachev.
Historical Precedents and UFC Policy
The UFC has adjusted division limits before. In 2012, it added the bantamweight (135 lbs) and featherweight (145 lbs) divisions after years of smaller fighters struggling to make weight. More recently, the introduction of the flyweight (125 lbs) and women’s flyweight divisions reflected the growing diversity of MMA athletes. However, the lightweight division has remained unchanged since its inception, despite clear evidence that top contenders are increasingly pushing the limits of the 155-pound standard.
The Welterweight Transition: Makhachev’s Next Chapter
Makhachev’s move to welterweight in November 2024 was one of the most anticipated title changes in modern MMA. Weighing in at 170 pounds for his welterweight debut, he dominated Jack Della Maddalena in a five-round war, showcasing his ability to translate his grappling mastery to a higher weight class. The victory solidified his status as one of the sport’s most dominant champions and provided a counterpoint to critics who argued he was undersized at lightweight.
For Poirier, the transition underscores a painful truth: Makhachev was always meant for a higher weight class. “He’s a welterweight,” Poirier said in a 2024 interview. “He’s a monster at 170. I don’t know why he stayed at 155 so long.”

- The fight highlighted the brabo choke’s effectiveness and Makhachev’s ability to use size, strength, and technique to dominate opponents.
- Makhachev’s move to welterweight in late 2024 suggests the lightweight division may no longer be a natural fit for elite athletes of his size.
- The debate has reignited discussions about expanding the lightweight division to 165 pounds or creating a super-lightweight class.
The Future of Weight Classes in MMA: Will the UFC Act?
As the UFC continues to globalize and attract larger athletes from wrestling, sambo, and other grappling-heavy backgrounds, the pressure to adjust division limits will only grow. Fighters from Dagestan, Chechnya, and other regions with strong grappling cultures tend to have naturally larger frames, making the 155-pound limit increasingly difficult to maintain without extreme measures. The Poirier-Makhachev saga serves as a case study for whether the UFC will proactively address size inflation or wait for a high-profile incident—such as a fighter suffering a severe injury due to a weight-cutting mishap—to force change.
For now, the promotion appears content with the status quo. The lightweight division remains one of the most competitive and marketable in the UFC, with stars like Islam Makhachev, Charles Oliveira, and Islam’s successor as champion drawing significant pay-per-view buys. However, if trends continue, the UFC may eventually face a reckoning—one where fighters, doctors, or even legislators demand reform to protect athlete health and ensure fair competition.
