In 2015, he revealed his diet to Muscle & Fitness and FiveThirtyEight counted it all up and found that Johnson consumes 821 pounds of cod in a year. Given that cod goes for about $1.75 per pound, that means he was spending about $1,400 per year on fish.
However, in early 2016, Johnson revealed via Business Insider's Dave Mosher that he cut cod out of his diet.
