He is 6ft 4in (193cm), 270-pounds (122.47kgs), and has a physique befitting his recent role as Hercules.

But for Dwayne ‘The Rock’ Johnson, his action-hero body doesn’t just come with a grueling workout routine.

The Hollywood star sticks to a strict daily diet plan – involving seven meals, 5,165 calories and 10 pounds of food.

The 43-year-old revealed his mammoth regime, which usually begins at 4am, to Muscle and Fitness magazine, to the amazement of his fans.

In between his dishes – which consist of a range meats, eggs, rice and vegetables – he also finds time to work out.

Walt Hickey from the website FiveThirtyEight, it adds up to 2.3 pounds of cod and 12 eggs, plus a hefty portion of steak and chicken.

Johnson eats roughly 1,000 calories worth of cod each day alone and spends around $1,400 a year on the fish, if he buys in bulk.

A man’s suggested daily intake for all foods is roughly 2,500.

Sean Evans, who works for Complex magazine, tried the mountainous diet out for himself.

For one day he managed six of the seven meals, interspersed with gym sessions.

It wasn’t easy for Evans, who admitted early on that he hated fish.

In a feature for the magazine, he said: “Ultimately, I failed to complete The Rock Challenge, but quite frankly it was fool’s errand from the jump.

“I still wear size 30 jeans like I’m a sophomore in high school. Dwayne Johnson, on the other hand, weighs close to 300 pounds and has a body that burns fuel like a furnace.

“Yet, for whatever reason (probably to make me puke on Internet TV), we didn’t compromise the diet a single calorie.

“I walk away with a newfound respect for Johnson. He’s an athlete-turned-professional wrestling icon-turned box office draw, and, at 43 years old, still wakes up at 4 a.m. so he can mainline sweet potatoes and flip monster truck tires.

“That sort of career path doesn’t happen unless you have something freakish driving you.”
