THE world was left in shock as Shane Warne passed away in Thailand on Friday, March 4.

The Aussie cricket legend was found motionless in his hotel room with a suspected heart attack being the cause of death.

Following his passing, it was revealed that Warne had been on an extreme “liquid diet” to lose weight.

What was Shane Warne’s liquid diet?

Shane Warne, 52, revealed he was planning to get back in shape for summer, sharing a throwback picture of himself on Instagram to show how he wanted to look.

Alongside the snap, he wrote: “Operation shred has started (10 days in) & the goal by July is to get back to this shape from a few years ago ! Let’s go.”

Warne’s manager James Erskine told Weekend Today: “He did go on these ridiculous sorts of diets and he just finished one, where he basically only ate fluids for 14 days and he’d done this three or four times.”

He added: “It was a bit all or nothing.

“It was either white buns with butter and lasagne stuffed in the middle, or he would be having black and green juices.

“He obviously smoked most of his life [but] I don’t know, I think it was just a massive heart attack. That’s what I think has happened.”

Warne was reported to be “buzzing with excitement” before his death and was said to have had a last meal of vegemite on toast.

What have experts said about the liquid diet?

The Heart Foundation’s chief medical advisor Professor Garry Jennings says low calorie diets can run the risk of putting the heart under extra strain.

He told The Sydney Morning Herald: “Mostly, these risks are on top of an underlying heart problem, they don’t come out of the blue.

“I doubt they could cause a heart problem just by themselves.

“Basically, if your metabolism, your handling of fluids, salt and other electrolytes gets completely out of whack, if you have a small heart attack, you’re more likely for that to turn into something serious with a rhythm disorder.”

As yet, no link has been established between Shane Warne’s liquid diet and his death.
