Bryson DeChambeau explains latest radical body transformation after ‘cutting life short’ with diet

Bryson DeChambeau is done with his 'Incredible Bulk' experiment.

Golf's mad scientist is reaping the rewards of healthier living by contending at the PGA Championship after years in the wilderness.

DeChambeau famously packed on the pounds during the COVID-19 pandemic in a bid to overpower his rivals.

The 29-year-old briefly shook the golfing world with his astonishing distance off the tee, weighing 17 stone after gaining 20 pounds in three months.

However, despite success at the 2020 US Open, DeChambeau's unhealthy lifestyle eventually caught up with him.

Even on the questionable standard of the LIV Golf tour, the Californian has struggled to compete - and he has just one top-ten finish in eight majors since his US Open triumph.

Speaking to the before this week's PGA Championship, DeChambeau revealed he 'ate everything and anything' before doctors told him his life was being cut short.

He said: “I just thought a lot of protein, a lot of carbs, you know. But there were a lot of refined sugars that was not good for the body.

"[The medics] did blood work, measured stuff in my gut biome and I was super inflamed.

"So they said, if you want to live a longer life, you definitely have to change your diet, because your gut’s not liking what's going on.

"So I did.”

Looking visibly slimmer at Oak Hill Country Club in Rochester, DeChambeau fired himself into contention with a first-round 66 on a brutal golf course.

The American removed corn, wheat, gluten and dairy from his diet last August - and the results were transformative.

He said after his round: "I lost 18 pounds in 24 days. It was crazy.

"It wasn’t fat. It was all water weight. You know how I looked before. I was not skinny.”

DeChambeau was still the sixth-longest player in the field off the tee, averaging 313.3 yards with the driver, but this was not the 'bomb and gauge' display that succeeded at Winged Foot in 2020.

The LIV Golf rebel found nine out of 14 fairways, despite hitting fellow pro Kenny Pigman with a wild shot on 18.

DeChambeau also hit 15 out of 18 greens in regulation and gained more than two stokes on the field in putting.

Having spent years experimenting with his body and his golf game, with injuries to show for it, his days as a mad scientist could be over.

"I want to be just stable now," he said. "I'm tired of changing, trying different things.

"Yeah, could I hit it a little further? Could I try and get a little stronger? Sure.

"But I'm not going to go full force. It was great. ... Shoot, I can hit my 8-iron 200 yards now. So it's an asset, and it was a fun experiment, but definitely want to play some good golf now."
