Aleks credits losing 9kg to changing her lifestyle and diet 'dramatically' following her split from ex-'husband' Ivan Sarakula.

She was partnered with real estate agent Ivan on MAFS, which was filmed between September and December last year, but they split before their final vows.

They reconciled off camera in early January, only to break up for good a month later. 

'I actually eat vegan now, with a bit of fish on the side. So you could call it pescatarian. Yeah, I've changed my diet dramatically, and I don't really like working out so I never workout. That's it,' Aleks said of her weight loss in April.

Instead of hitting the gym, she has taken to filming videos on TikTok, a social networking app.

She often shows off her lithe physique while performing dances on her account.

Meanwhile, Aleks' waistline isn't the only thing that's changed since her time on MAFS, as she also ditched her dark locks for lighter blonde tresses.
