'The Wolverine' star Hugh Jackman is worried he might suffer a heart attack because of the diet and training regime he has to undergo to prepare for his role in the film.
The 44-year-old actor, who stars as the titular character in superhero spin-off 'The Wolverine', said the diet he has to stick to when he gets in shape for the role worries him because he knows it's not good, reported Conatctmusic.
"It's not good for me to eat 6,000 calories a day. I have to eat a dozen eggs every day. The only way varying the diet works is eating chicken.

The star has to undertake a huge workout regime - which he hates - every time he plays the mutant and he said he thought people pushing themselves so hard for a similar goal were idiots.
"I used to go to the gym and see these guys pumping iron and I thought they were idiots. In what situation could you need to bench 350 pounds? I never understood the addiction, it's just painful. But that's what I do to become Wolverine," he added.
