The boxing world respects Tyson Fury as the figurative well-oiled machine that he is. After all, the 31-year-old Englishman pummeled everything in his way to become the near-consensus world heavyweight champion with a November 2015 unanimous decision over Wladimir Klitschko.

Fury, who got his shot at Klitschko by knocking out 18 of his first 24 opponents, remains unbeaten heading into his rematch with Deontay Wilder to settle the score once and for all following their December 2018 draw in Los Angeles.

But health fanatics would be shocked that such an amazing specimen – he wears his 255 pounds well on a 6-foot-9 frame – is able to perform so magnificently in the ring despite his one big guilty pleasure when he’s not training.

Gulp! Tyson Fury’s preferred drink is a surprise

Training to stay in shape between fights is different than the routine a boxer goes through in the eight to 10 weeks leading up to bouts. The workouts aren’t so much about maintaining stamina as they are about keeping the reflexes sharp. That gives fighters enough room to enjoy the fruits of their hard labor by partaking in the nightlife and not worrying so much about the dietary routine.

But Tyson Fury admits that he takes that freedom to the extreme in one specific way. Instead of replenishing his fluids with water or Gatorade after a few hours in the gym, Fury drinks a mind-boggling amount of soft drinks.

“I love me Diet Cokes,” Fury told the media ahead of his rematch with Deontay Wilder in Las Vegas.

“Love” qualifies as the understatement of the year. Fury admits to downing somewhere between 20 to 30 Diet Cokes a day. At the low end of the range and assuming he’s referring to the traditional 12-ounce cans, that’s nearly two gallons of soda a day containing 800 milligrams of sodium and 920 milligrams of caffeine.

Fury supporters will be relieved to know that he cuts out the two sodas per waking hour once he heads to training camp to prepare for fights.

Tyson Fury has a voracious appetite while training

Once the training gets serious, so too does Tyson Fury’s dietician. The heavyweight champion burns a lot of calories each day doing his road work and sparring during the run-up to bouts, so meals are carefully planned.

According to MensHealth.com, Fury’s day begins with fruit and yogurt for breakfast plus a pre-workout shake infused with 200 milligrams of caffeine. He downs more shakes during and after the workout, adding creatine, sugar, and whey protein to the blend.

Fury has not one but two lunches a day while in camp, mixing servings of chicken, seafood, and red meat. It’s all washed down with more shakes, which continue during a short workout between the two meals.

The entrée for the first of his two nightly dinners again consists of chicken, seafood or red meat. Fury will also have a second, lighter dinner at 9 p.m. consisting primarily of oatmeal, nuts, and almond butter. He indulges his sweet tooth with honey and dark chocolate.

Tyson Fury will carry extra wight into this fight

While some would expect the 6-foot-7 Deontay Wilder to be the fighter more interested in beefing up to avoid being pushed around, it’s Tyson Fury who has been talking about packing on extra pounds for the rematch between unbeaten heavyweights.

Fury has indicated that he may approach 270 pounds by the time the opening bell rings at the MGM Grand Garden Arena.

Fury is doing it by consuming up to 4,500 calories a day under a routine planned by George Lockhart, a former Marine and mixed martial arts fighter.
