She’s been on an incredible weight loss journey this year, dropping at least 18kg from her frame.  

And on Thursday, Rebel Wilson stunned her fans when she showed off her slimmed-down physique in a tight blue wrap dress on Instagram.

Rebel revealed in May that she was trying to get down to 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.

‘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.

Rebel has shed an incredible 18kg (40lbs or 2.8 stone) since kicking off her ‘year of health’.

‘Okay so for me 2020 is going to be called “The Year of Health”,’ she vowed in an Instagram post in January.

‘I put on the athleisure and went out for a walk, deliberately hydrating on the couch right now and trying to avoid the sugar and junk food which is going to be hard after the holidays I’ve just had, but I’m going to do it!’
