For most people, “I could eat a horse” is merely an expression. But we think that if anyone could make the idiom a reality, it might be Dwayne “The Rock” Johnson.

That’s because the 42-year-old actor and former wrestler, who is 6 foot 4 inches tall, polishes off about 5,165 calories a day (nearly double the daily calories an average American man consumes).

Johnson recently shared his diet with Muscle and Fitness magazine. He reportedly eats seven meals a day, and almost all of his meals consist of a protein, a carbohydrate and vegetables.

See a sampling of his meals below:

MEAL 1:

10 oz cod

2 whole eggs

2 cups oatmeal MEAL 5:

8 oz steak

12 oz baked potato

spinach salad MEAL 7:

30 grams casein protein

10 egg-white omelet

1 cup veggies (onions, peppers, mushrooms)

1 tbsp omega-3 fish oil

Walt Hickey of the website FiveThirtyEight says that based on this plan, Johnson eats about 10 pounds of food daily. He also devours about 821 pounds of cod every year, Hickey notes, adding: “The average American man in his forties consumes 2,734 calories daily, according to data from the USDA. Johnson eats roughly 1,000 calories a day in cod alone.”

Top athletes are known to feast upon plenty of food, Bleacher Report notes.

“Whether it be Michael Phelps or The Rock, they need to consume an enormous amount of calories to maintain their body and perform at a high level,” the news outlet reports.
