Tyson Fury may not have become an undisputed heavyweight champion but he certainly had the diet of one.

Fury, 36, took to social media on Monday afternoon to announce that he has brought down the final curtain on his boxing career. The Gypsy King departs the squared circle having lost two consecutive matches against Oleksandr Usyk in Saudi Arabia.

While his second loss was devastating, his first defeat may have been the most painful, as he had got into the shape of his life to face the Ukrainian. Fury did so with a perfectly tailored diet plan which catered to his enormous 6ft'9" and 262lbs frame.

In an interview with Men's Health, Fury's nutritionist Greg Marriott, who had worked with Fury since 2018, shared the diet plan and habits Fury took on to get himself in lean shape. Marriott said: "I do absolutely everything, I wake him up with his collagen.

"I don’t leave fighters to anything. I literally live with him. I sit with him. I make sure that I watch him take the vitamins. I don't want no stone unturned. For me, I give them 100% so I do everything."

While Fury was looking to lean up and shed some weight before his first clash against Usyk, Marriott did not put him on a heavily restricted diet plan. Instead, he steered into Fury's food preferences and adapted them to their fitness goals at the time.

Marriott added: "I’m not a nutritionist that loves to count calories. Because I’m looking every single day, checking the weight, looking at the body fat, I’m not a calorie counting nutritionist.

"Every boxer I work with has cheat meals. It just mentally does something to them, they look forward to it, but he's not demanding, you know, big dirty meals."

On a non-training day, Fury would consume 3,000 calories, and 4,500 calories on a training day. Below, was a typical day's eating for the Gypsy King as per Marriott's plan.
