Sylvester Stallone revealed that prepping for his iconic action roles drove him to extreme physical lengths, including dropping to 2.6 percent body fat and developing bulimia. The 80-year-old actor opened up about his health struggles during a promotional press tour for his new memoir, The Steps, shedding light on the hidden tolls of Hollywood vanity.
Sylvester Stallone Details Extreme 2.6 Percent Body Fat and Bulimia Struggle During Rocky III Prep
Veteran actor Sylvester Stallone has opened up about the punishing physical standards he maintained at the height of his franchise career.
During interviews promoting his memoir The Steps, which was released on September 29, 2026, the 80-year-old star shared that his pursuit of an ultra-lean on-screen appearance during the filming of 1982’s Rocky III crossed into a dangerous fixation. He revealed that his body fat index dropped to 2.6 percent during that period, far below the minimum 8 percent required for men in his age bracket of 20 to 69.
That dramatic transformation was entirely intentional. By the third installment of the boxing franchise, the creator wanted the character’s appearance to reflect growing wealth, vanity, and success before a beating from Clubber Lang, played by Mr. T, shattered that security. Reflecting on his past choices during a recent appearance at New York’s 92nd Street Y alongside CBS’s Tracy Smith, the actor noted that he once viewed his physique as a horse person might relate to animals, believing he was about the same intelligence as a horse during his early days. But maintaining that condition exacted a severe toll, and his diet at the time consisted of tuna fish and massive amounts of coffee.
“It became an obsession. Really bad. It got to the point where I became bulimic.”

He added that he could not keep food down because he had become completely obsessed with staying at that exact level of fitness, describing the routine as an obsessive body-worship kind of thing. Bulimia nervosa is characterized by consuming a large amount of food in a short amount of time, followed by purging behaviors such as vomiting, excessive use of laxatives or diuretics, fasting, or excessive exercise.
Sylvester Stallone Discusses Steroids and Surgical Rebuilds After Action Movie Roles
When questioned by Tracy Smith about how actors achieve extreme action physiques in a packed room at the 92nd Street Y, Stallone did not shy away from discussing performance-enhancing drugs, posing the question to the audience about whether they truly believed those physiques were natural. He explained that maintaining an enhanced appearance for months at a time on set required cycling steroids six weeks on and six weeks off, noting that achieving such a look involved additives and drugs rather than natural means alone.
“You think these guys are natural? No.”

He compared temporarily building a superhero physique to putting on a piece of costume that an actor wears for six to eight weeks before shedding it, though he acknowledged that coming off the drugs and watching the physique disappear could be psychologically difficult. The physical punishment extended beyond diet and pharmacology, as the actor treated his body like armor and frequently performed his own stunts. Decades later, that masochistic approach resulted in a long list of medical procedures, including nine back operations, two shoulder surgeries, and three neck fusions. He remarked that everything inside him is held together with baling wire,
adding that he takes numerous pills to keep going, considers himself sort of fit at age 80, and would advise his younger self to let stuntmen carry the heavy physical labor rather than doing his own stunts.
Experts Highlight the Hidden Rise of Eating Disorders Among Men and Adolescent Boys
Stallone’s public disclosure has brought fresh attention to an issue that clinical specialists describe as highly underreported. According to the National Association of Anorexia Nervosa and Associated Disorders, about 30 million Americans experience an eating disorder during their lifetime, with roughly one-third being male.
Specialists point to modern societal pressures, celebrity emulation, and online subcultures like looksmaxxing as drivers behind an increasing need for physical perfection among adolescent boys.

The sudden episodes, which made him feel hot and convinced that he was dying, continued to recur in crowded public spaces over the years, such as when filling up an art exhibition room with his wife, forcing him to drop to one knee in an alleyway. His health eventually faced a major reckoning during his career, and he also continues a busy creative schedule, working as an executive producer for an upcoming John Rambo prequel film and starring in the ongoing OTT series Tulsa King.
Today, as he promotes his memoir covering his life and career, the veteran actor continues to balance his desire to stay in shape with the heavy toll of his cinematic past, while biographical projects such as Peter Farrelly’s I Play Rocky—starring Anthony Ippolito and arriving in select theaters on November 6 before expanding nationwide on November 20—revisit the turbulent making of his breakthrough 1976 boxing movie.
