DWAYNE 'THE ROCK' JOHNSON eats seven meals a day.

The 'Fast and Furious' star is known for his great physique but it doesn't come without a lot of hard work as it has been revealed the star consumes 36 ounces of cod a day and starts exercising at four in the morning.

Revealing his diet and exercise plan to Muscle and Fitness, Dwayne starts the day with a cardio workout between four and five in the morning before enjoying a meal of cod, eggs and oatmeal.

He then works out for a further 90 minutes and then enjoys his six other meals spread throughout the day.

His other meals contain a mixture of fish, rice, vegetables with the former wrestler having an 8 oz steak alongside a baked potato and spinach for meal five.

Meanwhile, the 42-year-old actor previously revealed he changes his diet to suit which role he is playing.

He said: ''For different roles my condition and training and diet does alter. Depending on the role, it will really dictate the type of training I do.

''For 'Hercules,' it was a 22-week diet, while for 'G.I. Joe: Retaliation' it was about a 14-week diet, and for 'Pain & Gain' I wanted to come out looking bulky, big, and dangerous, so we adjusted accordingly.''
