Brie Larson adopted diverse diet plans tailored to each role she trained for. During the filming of “Room,” she drastically reduced carb intake to achieve a weight loss effect, creating a portrayal of a character who appeared to be undernourished. To preserve muscle mass, she incorporated a substantial amount of protein and vegetables into her diet.

In preparation for her role as Captain Marvel, Brie took a different approach, opting not to restrict any specific food groups. Instead, she emphasized well-balanced meals containing fiber, protein, fat, and carbs. She allowed herself occasional treats in moderation, such as enjoying a cookie or a donut after intense workouts.

Mindful eating was a crucial aspect of Brie’s approach, listening to her body’s signals of hunger and fullness. She did not adhere to specific food restrictions or strict rules, choosing to eat when hungry and stopping when full. Staying hydrated and active, Brie Larson consumed a significant amount of water throughout her journey.


While Brie Larson hasn’t officially confirmed intentional weight loss, her on-screen appearance in Lessons in Chemistry indicates a noticeable transformation from her Captain Marvel days. The change in her jawline, cheekbones, and reduced facial puffiness can be attributed to her demanding work schedule during the August 2022 filming and the physical demands of her roles. In this series, Larson’s character not only transitions from a chemist to a cooking show host but also takes on the physical challenge of being a part-time rower. Opting out of a stunt double, Larson committed to intense rowing training, as mentioned by the show’s director Sara Adina Smith. This dedication to authenticity likely played a role in the observed changes in Larson’s physique.


Brie Larson, a successful actress, has demonstrated exceptional dedication to her craft in various roles, showcasing discipline and determination by undergoing significant weight loss to meet the physical requirements for specific characters. To achieve her fitness goals, she adheres to strict workout habits and maintains a healthy eating plan.
