Rebel Wilson wears a face mask and shows off her incredible 20kg weight loss in activewear as she enjoys a hike in Los Angeles

Rebel Wilson declared in January that she was making 2020 her ‘year of health’.

And on Thursday, the 40-year-old flaunted her slimmed-down frame as she enjoyed a hike at Griffith Park in Los Angeles.  

The Australian actress, who has lost an estimated 20kg, wore a face mask and cut a casual figure in activewear on the outing.

Rebel wore a pair of black Nike leggings, layered black tops and a matching black and gold jacket.

She completed her look with black Nike sneakers and a navy cap, as she carried her phone during the hike.  

Rebel swept her blonde locks into a ponytail, and concealed her gaze behind a pair of cat-eye sunglasses.

Earlier this month, Rebel revealed she was only three kilograms (6.5lbs) away from reaching her goal weight of 75kg (165lbs or 11.8st).

At the time, she said that while she still treats herself, she’s found ways to indulge that don’t necessarily involve food.

‘Remember though girls, you still gotta treat yourself. I just do it with food now only once or twice a week… and substitute bubble baths on alternate nights,’ she wrote on Instagram on October 5.

According to a report by People in June, 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 the Austrian health and wellness retreat Vivamayr last year, and has continued to follow the plan. 

The Mayr Method is an approach that eliminates food intolerances, reduces sugar, encourages eating whole foods slowly, boosts the immune system and reduces inflammation.

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

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

It’s not the only change Rebel has undergone recently, as it was revealed last month that she’s dating Anheuser-Busch brewing heir Jacob Busch.

The couple have already embarked on a series of lavish holidays together, most recently to Cabo San Lucas in Mexico.
