UFC's Dana White shows off her shredded body after undergoing an incredible transformation before UFC 287.

MMA fans were left blown away after getting a glimpse of UFC boss Dana White’s new physique.

The veteran promoter has become somewhat of an iron junkie over the last decade and piled on several pounds of muscle a few years ago.

White, however, trimmed down his once-massive frame after being told by blood and DNA experts to change his lifestyle habits.

And judging from his new leaner and meaner physique, he’s clearly yielded their advice.

White shared a snap of himself relaxing on a luxury yacht in Miami with a buddy to his Instagram page on Saturday afternoon.

The 53-year-old was topless in the pool and showcasing a frame his fighters would be proud of.

White’s abdominal muscles – which were deeply carved – were popping through his skin as he soaked up the Miami sun.

MMA fans were blown away by White’s body, with one saying: “God damn, Dana is shredded.”

Another said: “Dana White is 53 years old. Absolutely incredible what you can achieve with diet, exercise and discipline.”

And another one said: “Dana White looking like he’s about to go on a run for the title.”

One remarked: “Damn, Dana White got shredded for #UFC287 in Miami.”

Another chimed in: “What is Dana White’s diet?”

White stunned UFC fans last year by revealing he had been given just TEN YEARS to live after visiting a health guru who conducted blood and DNA tests on him.

During an appearance on the Action Junkies Podcast: “This guy can take your blood and your DNA and tell you when you’re going to die. And he’s right within a month.

“How crazy is that? I had to know. I became f***ing obsessed with finding out the month I’m gonna die.

“I connect with this guy and they come in and do my blood work and they scrape the insides of your cheeks to do your DNA.

“The following Wednesday is when my results are supposed to be back.”

White then added: “He gave me 10.4 years to live.”
