"Dropped 10kgs over 14 days. Food deprivation made the experience multiple times harder, especially when enduring the cold."
In the first pic, Nick’s buff biceps almost take up the whole frame. In the second, he’s visibly emaciated, his six-pack abs and chest near concave.
He finishing the post with his trademark sense of humour, writing: "Ps: don't take a sword to a gun fight."
Many of his 454k followers weighed in on the post, including a slew of his celebrity mates.
“Wow good thing you carb-loaded before going in 👊🏽 ,” wrote Aussie cricketer Mitchell Johnson.
“Insane!! 😱” added his co-star Erin McNaught.
One summed up our thoughts exactly when they said, “SAS weight loss programme! Could be a side hustle here 😂”
Meanwhile, Nick is currently in the Northern Territory recovering from a shoulder reconstruction. He recently shared an update from his hospital bed.
“Big thank you to my nurses especially the first shift, they don’t get enough recognition,” he wrote. “3 egg and lettuce sangas and a truckload of average chat later and I’m almost back.”
Prior to the operation, he revealed that his doctors, friends and family members had all advised him not to take part in the series due to the risk of doing permanent damage to his shoulder.
“However, I do believe in the saying: 'Take the risk or lose the chance.' So I had a crack at it, and I believe the growth from that was unbelievable,” he reasoned. “It outweighs any pain that you'll feel. Pain is usually temporary, but regret lasts forever.”
Nick made it through to the finale episode, alongside comedian Merrick Watts and AFLW legend Sabrina Frederick.
The final challenge tested the final five recruits, including rally car driver Molly Taylor and James Magnussen, who were subject to an intense interrogation while bound and blindfolded in a freezing cold room.
After the testing episode, fellow winner Merrick revealed to Now To Love he'd also dropped a considerable amount of weight.
"I still have some niggling injuries. I had two fractured ribs and impact damage on my back."
"The thing that is unseen from a viewers perspective is we have completely exhausted our bodies and actually changed the physiology of bodies because they've gone into a survival mode. We lost muscle and became very skinny."
