Arg dined out with a couple of his co-stars for Dan Osborne's birthday dinner, which was held at steak restaurant Rare Cow in Essex, and he wasted no time in getting to grips with one of the biggest burgers we think we've seen!
Reality star Arg looked chuffed to bits as he posed with the burger, while sporting a pretty huge grin.
The only problem is... Arg is supposed to be on a diet!
Sharing the photo on Instagram (28 June), Elliott Wright said: "Funny dinner with the boys for Danny O's bday!! Arg attempting the burger challenge!! He's on a diet though!" Oops!
Arg went on a fitness kick before heading off to film TOWIE's Marbella special earlier this month, and since coming back, he has enlisted the help of Dan to be his personal trainer.
Dan told Arg in last night's episode (29 June): "If you want to train, I'll train you properly but you need to take it seriously. When you're at home, you can't be eating pizzas. You really can't."
Arg agreed, telling Dan: "You ooze a hell of a lot of sex appeal. I just need sex appeal Dan. I've got zero sex appeal."
Also in last night's episode, viewers saw Lydia Bright's mum Debbie Douglas make her return, where she gave her opinion on Arg's true feelings for ex-girlfriend Lydia.
"He is really trying to lose weight," Debbie told the fellow Essex mums. "He feels if he loses weight, he will win Lydia back."
We suppose Arg's burger challenge can count as his cheat day!
