Rebel Wilson shows off her incredible 77lbs weight loss in Fiji

She has been on an incredible weight loss journey over the past year.

And on Wednesday, Rebel Wilson proved her hard work is paying off as she showed off her slimmed-down figure on Instagram.

The actress, 41, flaunted her slender frame in a purple swimsuit and a flowing pink sarong as she relaxed on a private island in Fiji.

Rebel wrapped a pink sarong around her waist as she stood alongside a small boat and posed for the camera in a snap she shared with her followers on Instagram.

‘All I need is a volleyball. Wilsonnnnn!!!!!!!!! (Fiji happiness coming soon), she wrote, referencing Tom Hank’s film Cast Away.

The Bridesmaids star proudly announced last November she had reached her goal weight of 75kg (165lbs or 11.8 stone). 

According to People magazine, Rebel’s remarkable transformation is partially down to following the Mayr Method diet plan.

A source told the publication she got ‘amazing results’ by changing her eating habits while staying at an Austrian health and wellness retreat last year, and has continued to follow the plan.

‘It’s an approach that eliminates food intolerances, reduces sugar, encourages eating whole foods slowly, boosts the immune system and reduces inflammation,’ a source said.

‘She exercises with a personal trainer up to six times a week, goes on walks and is trying to up her protein intake nutritionally.’

Earlier this month, Rebel told Today Health she had developed a newfound love of walking.

‘I feel like sometimes people think you need to work your body really hard to get results, and yeah, if you were training to be the next Thor or something you would be doing hardcore things, but as a regular person, walking is just so healthy for you,’ she said.

Rebel said she loves to ‘put in a podcast or listen to music’ during her walks, and praised the physical activity for being ‘so easy to do anywhere in the world’.

‘I can just go out and do it. It’s become my favourite form of exercise right now,’ she added.
