Rebel Wilson shows off her incredible weight loss

Rebel Wilson revealed in January this year that 2020 would be "The Year of Health" and the actress has certainly stuck with her promise, showing off her incredible weight loss on Instagram.

The 40-year-old shared a snap on Thursday of herself in an all-black outfit as she posed in front of the ocean.

She jokingly captioned the snap, "Honey I’m home (where I’ve been for months).

"Looking flawless," one fan wrote, "Thank you for being an inspiration Ms. Wilson," another added.

Someone else wrote, "You are looking FAB-U-LOUS my dear."

People Magazine reports the actress has lost 18kg so far since visiting Austria's luxury medical detox and wellness centre VivaMayr last year.

The mag reports that Rebel got "amazing results" by following the Mayr Method diet plan and has continued ever since.

The diet is based on the Mayr Cure by Dr Franz Xaver Mayr, an Austrian physician who believed that most people are poisoning their digestives systems with the type of food they eat and how they eat them.

The diet eliminates snacking, reduces gluten and dairy products and changes how clients chew their food.

Jezebel reports that while at the wellness centre you are not to speak, read or text while you eat.

"All three meals of the day are eaten in silence in the dining room, which sits on a patio overlooking the lake. You are assigned your own table, which is yours for the entire length of the stay. You should not be speaking, reading, or texting while you eat, and you are encouraged to chew each bite of food 30 times before swallowing."

They also revealed that the allowed foods consisted of vegetables, fish and sheep's milk yoghurt.

A source told People, "[Rebel] exercises with a personal trainer up to six times a week, goes on walks and is trying to up her protein intake nutritionally."

"I know she's also been working on conquering her emotional eating patterns of behaviour."

Rebel revealed on Instagram in May that her goal is 75kg.
