Sylvester Stallone Says He ‘Became Bulimic’ After Transforming for ‘Rocky’ and Opens Up About the ‘Terrible Toll’ of Steroid Use: It Was An ‘Obsessive Body-Worship Kind of Thing’

Sylvester Stallone has revealed the severe health costs of his physical transformation for "Rocky," disclosing that he developed bulimic patterns and became dependent on steroids during his pursuit of the iconic boxer role. Speaking to The New York Times, the actor described a decades-long struggle with his body image that began when he first prepared for the 1976 film and intensified through his subsequent action-star career.

Stallone characterized his relationship with his physique as an "obsessive body-worship kind of thing," one that extracted what he calls a "terrible toll" on his physical and mental health. The actor attributed much of this obsession to the demands of playing Rocky Balboa, a role that required him to achieve a specific muscular aesthetic that became the blueprint for his on-screen persona throughout the 1980s and 1990s.

The admission pulls back the curtain on a rarely discussed aspect of Hollywood's glamour machine. Male action stars of Stallone's era operated under brutal physical standards, often without the modern medical oversight or mental health support that contemporary actors receive. Stallone's openness about bulimia and steroid abuse reflects broader conversations now happening in entertainment about the cost of transformative roles and the industry's historical indifference to performer wellness.

"Rocky" launched Stallone from relative obscurity to global stardom in 1976, and the film's success created an expectation that he maintain that physique. Sequels followed rapidly. The "Rocky" franchise demanded consistency. Stallone moved into action films with "First Blood" and the "Rambo" series, genres where muscularity became as essential to casting as acting ability. The pressure to remain visibly jacked created a self-perpetuating cycle. Each film required him to look more imposing than the last.

Steroids became the shortcut to sustaining that look, but Stallone describes the drugs as having reshaped not just his body but his psychology. The use wasn't incidental or recreational. It was systematic, tied directly to his professional viability in an industry that equated his physical form with box office returns. The bulimia suggests that even as he built muscle through pharmaceutical assistance, he battled the psychological need to control his body through purging, a common pattern among those with disordered eating behaviors.

This disclosure carries weight now, decades into his career. Stallone continues acting at 78, recently starring in the "Samaritan" superhero film and reprising Rocky in the "Creed" franchise. He's proven his longevity transcends the specific physique that defined his 1980s peak. Yet the damage from those years persists. Speaking publicly about the mental and physical toll acknowledges that the cost of being a movie star in that era was steeper than audiences ever saw.

Stallone's candor matters beyond his personal story. It contextualizes Hollywood's relationship with male bodies during a particular moment in entertainment history. It explains why so many action stars from that generation struggled with substance abuse, why several died prematurely, why the industry's current emphasis on mental health support and safer training protocols exists at all. His experience wasn't unique. It was standard. The difference is he's now talking about it.
