Jackson made his extraordinary diet revelation last week on SAS Australia when his co-stars noticed that he seemed confused by this dinner offering. 

Convicted drug smuggler Schapelle Corby, 43, had to explain that it was tomato soup, and it was ‘good’ to eat. 

While filming SAS Australia in August, Jackson had the opportunity to eat a variety of foods he’d never tried before, including sushi, pineapple, rockmelon, mandarins and even steak. 

In an interview with news.com.au, he explained that his limited diet consists of: ‘Eggs, bacon, toast, cereal, burgers, nachos, chips, apples… that’s about it.’

The model went on to reveal his typical day on a plate starts with ‘eggs, bacon and an oat shake’ for breakfast, and he would eat ‘burgers, protein shakes, pasta or lasagna’ for lunch and dinner.

On Monday’s episode, Jackson told viewers he didn’t consider himself ‘famous’.

He went on to say that while he hasn’t had much ‘life experience’, he signed up for SAS Australia to test himself, both physically and mentally.  

While praise isn’t often given to recruits by Directing Staff on the show, drill sergeant Mark ‘Billy’ Billingham told Jackson he was ‘a f**king impression person’ after his marksman task.
