His manager said that Shane Warne had just completed an "extreme" 14 day liquid diet, before he succumbed to a heart attack.

Just four days before his death in Thailand, the cricket legend said he was going to "operation shred".

The 52-year-old Aussie idol shared a throwback photo of himself last week on Instagram to show how he wanted it to look.

He also wrote, "Operation Shred" (10 days in), and the goal is to return to the shape of a few years back by July! Let's go."

James Erskine, Warne's long-time manager, revealed on Sunday how drastic he took to reduce his height and that he only just completed an extreme and "ridiculous cleanse."

It is...

• Shane Warne had complained of chest pains and was seen by a doctor to examine his heart just weeks before his tragic death.
• The cricketing legend spent his last hours shopping for a suit and getting massages
• "Paramedic so sorry" that he could not save Warne's lives as he and his friends tried to revive him
• After confirming that Shane Warne's death was not suspicious, forensic officers inspect Shane Warne’s Thai villa.

Weekend Today spoke with him: "He did go to these ridiculous kinds of diets, and he just completed one, in which he basically only ate fluids 14 days. He'd done this three or patru times."

He said, "It was a little all or nothing."

"It was either white bread with butter and lasagne in the middle or black and green juices.

"He clearly smoked for most of his life, but I don't know if it was a major heart attack. This is what I believe has happened.

Andrew Neophitou, a friend of the Aussie sporting legend, found him unresponsive in his bedroom at their luxury villa on Friday.

Since then, Thai police have confirmed that they have ruled all suspicious circumstances out.

Officers also used information from the cricketer’s family to confirm that he had heart problems and asthma. Superintendent Yuttana Sisombat confirmed that Warne had had chest pains prior to his death and had seen a doctor about it.

Warne's body arrived at a local hospital in a motorcade, flanked by the Australian ambassador as well as local police officers.

He will be transferred by ferry to Surathani on the mainland, where an official autopsy is performed.

His family accepted an offer for a state funeral once his body has been repatriated to Australia.

This comes as James Erskine, the manager, sheds light on the final moments of Shane Warne in a Fox Sport special, Remembering Shane Warne.

He claimed that the group was due to meet for drinks at 5pm. However, Andrew Neophitou, a pal of his, knocked on Andrew's door and realized "something was wrong".

James said, "He went into there and said, 'come on. You're going to miss your flight'. Then he realized something was wrong.

"And he turned the patient over, giving him CPR and mouth-to-mouth for about 20 minutes. The ambulance arrived.

"They took him to hospital, which was approximately a 20-minute drive. I received a call 45 minutes later confirming that he had been declared dead."

Warne had watched the Australian Test cricket team take on Pakistan from his bedroom, before the tragedy struck.

At the village, he was given a Thai massage and "looked lively & happy" after it was over.

Cops took photos of the room while forensics teams worked at the PS2,000-a night villa.

'DESPERATE'

SE was told by Anuch Haniam, a paramedic, that Shane's friends had already tried to bring him back to health.

"I took over CPR while we waited to get an ambulance.

"They were desperate. One was probably crying. They were very stressed and panicked.

"They tried to wake him, but he didn't sleep. I heard someone say, "Come on Shane. "Come on Shane."

"I tried my best to help him, and I gave my all. "I'm sorry I couldn't help but to be there for him."

For the cricket ace, led by Liz Hurley, tributes have been flooding in.

The actress was in a three-year relationship with Warne until their split in 2013.

She stated, "I feel as if the sun has disappeared behind a cloud for good." My beloved Lionheart, RIP."

Piers Morgan called his friend "uniquely ferocious and mischievous" when he wrote a column for SE.

He said, "I am absolutely devastated that he has gone so quickly and will miss him immensely."

"But I enjoyed every minute of his exhilarating and unpredictable company. And how many people can you say that?"
