Rebel Wilson is looking as glamorous as ever as she continues her “Year of Health mission” to get down to 165 lbs. by the end of 2020.

On Saturday, the Australian actress, 40, got all dolled up to celebrate her pals, Carly Steel and Jacob Andreou, and their recent nuptials. The former Entertainment Tonight host tied the knot with Andreou, the Vice President of Product at Snapchat, on June 27 in an intimate ceremony at the historic Beverly Hills Presbyterian Church in front of eight family members.

"Congrats [Carly Steel] and [Jacob Andreou] aka my former thrupple," Wilson joked on her Instagram Story.

The Pitch Perfect star also shared several photos of her glamorous ensemble for the summertime celebration. She opted for a belted yellow Wayne Cooper dress and makeup done by Matthew Vanleeuwen. Celebrity hair stylist Robert Vetica helped Wilson beat the heat on the "hottest day of the year" with an elegant high-ponytail updo.

Earlier this year, the star opened up to her fans about her 2020 goals, sharing that she is trying to slim down to 75 kg., or 165 lbs., before the end of the year. To achieve this feat, Wilson's personal trainer, Jono Castano, recently told Yahoo! Lifestyle that the star has been using a wholistic approach, focusing on both nutrition and exercise.

"You can't out-train a poor diet and you can't let the weekend derail your fitness goals. It's a key mistake that a lot of people make. They get to the weekend and everything goes down the drain and then basically Monday to Friday, all the hard work that they did is gone," Castano explained. "I'm all about balance, so with me, if you're going to have one drink, whatever it is, a chocolate, that's totally fine as long as it fits into your calorie count."

In terms of eating, a source told PEOPLE that Wilson has been following the Mayr Method diet plan, which is based on the “Mayr Cure,” created by Dr. Franz Xaver Mayr, an Austrian physician, nearly 100 years ago. Mayr believed that most people are poisoning their digestive systems with the foods they eat and how they eat them.

“Everything starts with the gut,” Dr. Christine Stossier, assistant medical director of VivaMayr, a luxury medical detox and wellness center in Austria, told The Guardian in 2017. Using Mayr’s philosophy, the center revamps their clients’ diets to eliminate snacking, reduce gluten and dairy intake and change how they chew their food.

“The fundamental principle is that you can improve someone's health through digestion,” Stossier added.

Meals are centered around very slowly eating whole foods with high alkaline content, like vegetables, fresh fish and sheep’s milk yogurt. At breakfast, clients are given hearty spelt bread so they can train themselves to focus on consuming slowly — VivaMayr instructs them to count out 30 chews per mouthful, according to Jezebel.

The act of eating is given increased importance at VivaMayr to aid in digestion. Clients cannot have their phones with them at meals, which are scheduled at least four hours apart, and they do not drink water while they’re eating.

“It's an approach that eliminates food intolerances, reduces sugar, encourages eating whole foods slowly, boosts the immune system and reduces inflammation,” the source close to Wilson told PEOPLE last month.
