He is set to step back into the spotlight this summer, with the hit show Entourage making its debut on the big screen.

And actor Jerry Ferrara is certainly ready for it, having lost 40 lbs in a dramatic weight transformation.

Talking to New You Magazine, the 35-year-old has revealed that his biggest struggle is trying to keep the weight off.

"What happened [after losing the weight] was a whole lifestyle change. I devoted myself to working out, quit smoking, committed to an annual physical."

Ferrara - who plays Turtle on Entourage - also admits that it has done wonders for his career.

"It did great things for my career. I mean, I was cast as Gabrielle Union's love interest [in Think Like a Man Too]."

He added: "I had to prove to an audience I could actually get her! That was not going to happen before."

The actor reveals that his lifestyle change came after he was asked to take a medical examination.

"During season six, about three months shy of my 30th birthday, I had to take a physical. The doctor was really diligent in checking me out," he explained.

"I passed the exam, but I weighed about 200 pounds (90 kilograms) and I'm 5'7". It's hard to carry 200 pounds on that frame.

"He said, 'Right now, you're fine. But if you continue on this path, by 39 you might start having problems'.

"It's a lot harder to start taking care of yourself when you're 39 than when you're 29."

Entourage hits New Zealand cinemas on June 4.
