This is the eating plan Rebel Wilson is using to lose weight

Pitch Perfect star Rebel Wilson is on a mission in 2020 to lose weight and get healthier. The Aussie actress, who turned 40 in March, wrote on Instagram in May that this is her "Year of Health," and she's aiming to reach 165 pounds by the year's end.

Wilson shared on Instagram, "Even if you have to crawl towards your goals, keep going x it will be worth it. Try and give a little bit of effort each day...I know some days are frustrating as hell, you feel like giving up, you get annoyed at the lack of progress...but good things are coming your way." Wilson has a plan, though, according to People. After visiting Austria's VivaMayr in 2019 and finding success with its Mayr Cure, she's kept it up at home. 

VivaMayr is a state-of-the-art health and wellness facility that specializes in fixing people's diets to not just help them lose weight, but eat the best foods for their bodies. Though The Guardian described the Mayr Cure as an extreme detox popular to the rich and famous, Dr. Christine Stossier, assistant medical director at the clinic, said the method works to fix digestive problems. "Everything starts with the gut," Stossier said to The Guardian. "The fundamental principle is that you can improve [someone's health] through digestion."

Rebel Wilson is focused on breaking the habit of emotional eating

The Mayr Cure, which is the eating plan Rebel Wilson is reportedly using, was created more than 100 years ago by Dr. Franz Xaver Mayr. It shows people how to cut back on foods that are notoriously hard to digest, like dairy and gluten, and chew your food long enough to digest it better. 

According to Noël Duan, a writer at Jezebel who went to VivaMayr and spent weeks learning the Mayr Cure, the plan demands you "eat slowly without distractions, allow at least four hours between meals for digestion, don't drink water while you're eating, and eat simply and seasonally." And while a stay at the wellness center starts as a detox, it's actually teaching you long-term habits to take home with you, including eating high-alkaline foods and chewing properly. 

Wilson is pairing her new eating habits with a workout routine that she regularly posts about on Instagram. She posted a triumphant photo after a Sunday workout on June 21, 2020, showing off her already trimmer figure in all black, proving that all her hard work is paying off.

For now, Wilson is focused on getting to that healthy weight for herself. A source told People that Wilson is really focused on breaking her habit of emotional eating, which is exactly where the Mayr Cure should come in handy.
