Matt Damon Shares a Diet Change That Helped Him Improve His Fitness

Actor Matt Damon has spent decades taking on physically demanding roles, but his preparation for an upcoming film directed by Christopher Nolan required a renewed level of focus. Damon is set to portray Odysseus in Nolan’s highly anticipated film Odyssey, and the role called for a lean yet powerful physical presence. At 55, Damon said the transformation was not about chasing a particular look, but about meeting the demands of the character and honoring the expectations of the project. As he explained, maintaining the right physical condition has long been part of his professional responsibility.

Speaking on the New Heights podcast hosted by Jason and Travis Kelce, Damon shared insight into how he approached the process. He described the preparation as similar to how professional athletes train for competition, emphasizing routine, consistency, and discipline. Damon noted that early footage from the film showed noticeable changes, and he confirmed that he had leaned out significantly over the course of filming. According to Damon, once the training and diet become part of daily life, the challenge shifts from effort to maintenance—staying steady rather than pushing extremes.

One of the changes Damon mentioned was removing gluten from his diet, a decision he said aligned with conversations he was already having with his doctor. He explained that this adjustment was part of a broader, carefully managed plan rather than a quick solution. During filming, Damon said his weight dropped to around 167 pounds, a number he had not seen since his youth. He stressed that the transformation came from a combination of structured training and a strict but intentional eating plan, not from a single dietary choice alone. Damon framed the experience as a professional commitment rather than a lifestyle recommendation.

Health experts generally caution against assuming that eliminating specific foods automatically leads to weight loss. Medical professionals note that while some people avoid gluten due to medical conditions or sensitivities, weight changes often occur because individuals become more mindful of overall food choices. Diets that emphasize whole foods such as fruits, vegetables, lean proteins, and legumes can naturally be lower in calories and more nutrient-dense. Damon’s experience reflects a personalized approach guided by professional advice and the unique demands of his role. As he made clear, what worked for him was about preparation, structure, and intention—qualities that, for him, are as essential to acting as learning lines or stepping onto a set.
