Anthony Joshua’s diet consists of 5,000 calories a day as the heavyweight champion prepares for his showdown with Wladimir Klitschko.
The boxer’s nutritionist Mark Ellison says Joshua trains like a middleweight and eats like a champion.
Joshua is preparing for the biggest fight of his career when he takes on Klitschko at Wembley on April 29.
Ellison revealed that the heavyweight is unlike anyone he has ever worked with.
The 27‑year‑old’s lunch consists of salad, two baked potatoes and a big portion of tuna or salmon.
Joshua will close out his day with chicken, white rice, pitta bread or mashed potatoes and vegetables for dinner with the calorie count topping 5,000 on the days where he trains up to eight hours.
The Olympian is undefeated in his professional career with 18 knockouts from 18 fights.
