Dwayne Johnson’s Weight Loss: Inside the Star’s Stunning Transformation

Dwayne Johnson’s weight loss has taken Hollywood and fans by storm, with the former wrestler and action movie icon debuting a dramatically leaner physique at the 2025 Venice Film Festival.

Known for his Herculean muscles and larger-than-life presence, Johnson’s slimmer frame has sparked curiosity and speculation. This article dives into the reasons behind his transformation, exploring the roles, motivations, and methods that led to this jaw-dropping change.

From film preparations to career shifts, here’s everything you need to know about The Rock’s new look.

Why Did Dwayne Johnson Undergo Such a Dramatic Transformation?

Johnson’s weight loss is primarily tied to his role as MMA fighter Mark Kerr in the A24 biopic The Smashing Machine, which premiered at the Venice Film Festival on September 1, 2025.

To authentically portray Kerr, a two-time UFC heavyweight champion, Johnson shed approximately 60 pounds, moving away from his signature bulky physique.

He explained that the transformation was driven by a desire to capture Kerr’s unique silhouette and physicality, requiring specific training to mimic the fast-twitch muscle movements of an amateur wrestler.

This shift marked a departure from his typical action-hero roles, showcasing his commitment to dramatic, character-driven storytelling.The actor’s preparation didn’t stop there.

Johnson revealed at the Toronto International Film Festival on September 8, 2025, that he is slimming down even further for his next project, Lizard Music, a whimsical film based on Daniel Pinkwater’s novel.

In this role, he’ll play a 70-something-year-old eccentric called the Chicken Man, alongside a 70-year-old chicken named Claudia. Johnson jokingly noted he’s eating “less chicken” to prepare, indicating a continued weight loss journey to fit the character’s leaner, older appearance.

How Did Johnson Achieve His Weight Loss?

While specific details of Johnson’s diet and exercise regimen for The Smashing Machine and Lizard Music are not fully disclosed, his approach was deliberate and disciplined.

For The Smashing Machine, Johnson underwent specialized training to replicate Kerr’s MMA and wrestling movements, which likely involved a mix of high-intensity workouts and a reduced-calorie diet to shed muscle mass.

Unlike his previous roles, where he consumed up to 8,000 calories daily to maintain his massive frame, this transformation required a significant reduction in muscle mass, not fat.

Experts, such as Kunal Makwana cited in the Daily Mail, suggest Johnson’s weight loss was achieved through natural methods like diet and exercise, dismissing speculation about weight-loss drugs.

Johnson’s history of tailoring his physique for roles provides context. For Black Adam in 2022, he told Men’s Health that he aimed for the “best physique” of his career, involving constant tweaking of his diet and workouts.

For The Smashing Machine, the goal was the opposite: to slim down while maintaining authenticity. Posts on X have speculated about other factors, such as potential cessation of performance-enhancing drugs or testosterone replacement therapy, but these claims lack verifiable evidence and are not supported by Johnson’s statements.

What Does This Mean for Johnson’s Career?

Dwayne Johnson’s weight loss signals a pivotal shift in his career trajectory. Known for action-packed blockbusters like Fast & Furious and Jumanji, Johnson is now exploring more nuanced, dramatic roles.

The Smashing Machine earned a 15-minute standing ovation at Venice, with Johnson and co-star Emily Blunt moved to tears, indicating critical acclaim for his performance.

This role, directed by Benny Safdie, allowed Johnson to tap into Kerr’s struggles with fame, addiction, and personal challenges, showcasing his acting range beyond physicality.

His upcoming project, Lizard Music, further highlights this evolution. The quirky, character-driven story contrasts sharply with his action-hero past, suggesting Johnson is breaking free from Hollywood’s tendency to pigeonhole him as “The Rock.” As he told The Hollywood Reporter, a “little voice” inside pushed him to explore what more he could achieve creatively.

This transformation, both physical and professional, positions Johnson as a versatile actor willing to take risks for art.

How Have Fans Reacted to The Rock’s New Look?

The public’s response to Johnson’s slimmer physique has been mixed, with reactions ranging from shock to admiration.

At the Venice Film Festival, fans on X expressed disbelief, with some nicknaming him “The Pebble” and others praising his dedication. Comments like “Had to do a double take” and “The Smashing Machine is setting the bar high” reflect the surprise and excitement.

However, some fans voiced concern, drawing parallels to past celebrity weight loss controversies, though supporters quickly clarified that Johnson’s change was intentional and role-driven.

Despite the chatter, Johnson’s commitment to his craft has won over many. His emotional response to the Venice ovation and his candid discussions at TIFF about his career evolution have resonated with audiences, reinforcing his status as a beloved figure willing to push boundaries.
