Rebel Wilson's weight-loss journey: Her 'Year of Health' diet and workout

According to Good Housekeeping, Wilson traveled to Austria to visit the VivaMayr clinic, where she learned about the clinic’s approach to diet and exercise. The clinic costs quite a bit, even just a consult, and there’s a tight daily schedule for patients who stay there, but Wilson took her health education to-go, training and dieting in her own life.

The regimen focuses on gut health by increasing fiber intake and decreasing gluten. High-alkaline meals include lots of vegetables and fish. Some weeks Wilson has followed a stricter 1,500-calorie, high-protein diet, but she says she is more stable at about 2,000-2,500. The Mayr Method also requires patients nix snacking and do some fasting.

Wilson told People that she has found a lifestyle balance by occasionally going off her diet program for treats, which only helps sustain her long-term goals. As her trainer, Jono Castano, says, getting healthier is a marathon, not a sprint.

According to Women’s Health, Wilson’s exercise routine includes a lot of high-intensity interval training using full body movements. In videos on her Instagram (and her trainer’s account), Wilson can be seen flipping tires and using battle ropes, boxing and stair sprints, and generally staying active.

During an interview with Drew Barrymore on her CBS talk show, Wilson explained that much of progress was also thanks to a focus on her mental health. She said her international fame had driven more stress eating, so breaking down those impulses and reassessing her own mental wellness was key to finding a diet that worked for her.
