The reality star and singer, who dates co-star Lydia Bright, has been open about his battle with weight over the years, and the numerous diets he's tried to shift the excess pounds.
He had said in a recent TOWIE episode: "Enough's enough, I need to get this weight off once and for all... hell yeah!"
So in tonight's episode he enlists the help of Tommy and Diags as he signs up for a weight loss class, which is no doubt good news for Lydia, as tonight she also shares her concerns with mum Debbie about Arg.
Arg had hinted last week he was ready to take major steps to change his lifestyle, sharing aa His caption read: "I'm getting back to this ASAP, Watch this space!!!"
He lost around four stone last year after embracing a new healthy eating, exercise and no alcohol regime, following his voluntary stay in rehab over Christmas 2014, after his partying lifestyle got out of control.
Arg also appeared in reality show Sugar Free Farm, which challenged celebrities to change their unhealthy eating habits.
He told The Mirror in February: "I've been enjoying myself and eating more and you go a bit mad over Christmas. Losing weight isn't really at the forefront of my mind."
The drama continues in The Only Way Is Essex on Sunday 28th March at 10pm on ITVBe
