In Season 8 of NCIS, Sean Murray, who plays Timothy McGee, underwent a noticeable weight loss. Contrary to speculation, this transformation was a personal decision rather than a character-driven choice.
Murray shared details about his weight loss on Twitter, explaining that he followed a strict diet for 14 months, which included no alcohol, minimal sugar, and a focus on organic foods. His efforts resulted in a loss of 25 pounds, and the change was positively received by fans. While the show did not explicitly address his altered appearance, it paralleled McGee’s character growth as he became a more confident and respected senior special agent.
