HUGH JACKMAN fears extreme dieting will cause a heart attack.

The Boy From Oz  has to chow down for his intense workout everytime he has to play X-Men’s claw crushing WOLVERINE- both in the team-up flicksd and then his stand alones.

To gain mass, Jackman binges on poultry – chicken AND eggs to reach of his goal of 6,000 calories a day.

But when he’s not flexing his fierce Adamantium claws, Hugh is extreme dieting.


To play Jean Valjean in 2012′s Les Miserables, he ingested nothing but liquids to shed the pounds.

“It’s not good for me to eat 6,000 calories a day,” Hugh told UK’s Notebook magazine.


“I have to eat a dozen eggs every day… The only way that seems to work is eating chicken… Lots and lots of chicken.


“I worry I’ll have a heart attack.”
