Overview

• Sacha Baron Cohen debuted his new muscle-bound form on the July 23 cover of Men’s Fitness UK to mark his transformation for the villain role of Mephisto.
• He credits a three-week regimen of short, intense workouts, a high-fiber, high-protein low-sugar diet and off-label Ozempic use for sculpting his physique.
• The actor enlisted trainer Alfonso Moretti—recommended by Matthew McConaughey—and squeezed 25-minute sessions into his filming schedule.
• Mephisto first appeared in the Ironheart finale on July 1, and Marvel Studios chief Kevin Feige has confirmed the devilish supervillain will return in future MCU projects.
• Cohen’s dramatic physical overhaul marks a notable shift from his comedic alter egos and mirrors a broader celebrity trend of using Ozempic for weight loss.
