The couple first met on season five of The Bachelor in 2017 and became engaged in April last year while on a ‘babymoon’ holiday in Fiji.

In July 2018, Laura’s personal trainer, Jono Castano Acero, revealed her body secrets in an interview with Daily Mail Australia. 

‘Training volume is usually four days [a week] due to her busy lifestyle, but it just shows all you need to do is put 45 minutes aside and you’ll reach your fitness goals,’ he said at the time.

‘We stick to HIIT [high intensity interval training] for two days, and then two days with a hypertrophy [building muscle] approach, where we just focus on legs and abs.’

Laura supplements her gym routine by following the ketogenic diet at home.

‘She has five meals a day: breakfast, mid morning, lunch, mid afternoon and dinner, which include animal proteins and non-starchy, above-ground vegetables like broccoli, Brussels sprouts and spinach,’ Jono explained.

‘She also eats fruits low in carbohydrates like avocado, berries, lemon and lime, fats, nuts, seeds, oils and high-fat dairy.

‘Some dairy can kick the body out of ketosis when the carbohydrate content is too high.’
