Rebel Wilson weight loss before after photos show one of Hollywood's most honest transformations. She lost 75 pounds during her self-declared Year of Health in 2020.

Working with trainer Jono Castano, Wilson trained for two hours each day — HIIT sessions, resistance training, hiking, and core work. Consistency was her key to shedding 75 pounds.

Wilson followed the Mayr Method diet emphasizing gut health and high protein. She cut processed sugar and focused on lean meats, vegetables, and mindful eating for sustainable results.

Rebel Wilson confirmed trying Ozempic during her transformation but stressed it was one tool alongside exercise, diet changes, and emotional health therapy for her PCOS condition.

Diagnosed with PCOS, Wilson was motivated by fertility goals. Her health journey led to welcoming daughter Royce Lillian in November 2022, her greatest reward for the Year of Health.
