Bryson DeChambeau has put three stone on over the last nine months and the newly-crowned US Open champion has revealed how.
DeChambeau won his maiden Major as he lifted the US Open at Winged Foot after a six-shot victory.
He has been helped by his new look recently, packed with muscle, as he smashed a 428-yard drive during the Travelers Championship.
DeChambeau, 26, has radically changed the way he eats and gone up from a size medium shirt to extra large after working hard in the gym.
And the new major champion talked through his ridiculous diet, which sees him put up to 6,000 calories away each day.
He said: “In the mornings I usually have four eggs, five pieces of bacon, some toast and two protein shakes.
“Then throughout the course of the day I’ll have a GoMacro [protein] bar here and there.
“I’ll have a peanut butter and jelly sandwich. I’ll have another protein drink.
“I’ll have at least two protein drinks on the golf course – every six holes. Then after the round I’ll have one.
“After that I’m snacking when I’m practising afterwards. Go back to the hotel, eat dinner. Steak and potatoes.
“Then I’ll have two protein shakes with it there as well. I’m consuming six to seven protein shakes a day.
“I used to be on two or three. I’ve upped the weight. Upped everything. I’ve had to consume a lot more.”
DeChambeau hit just 23 out of 56 fairways in regulation during the week, the fewest of any champion since 1981.
And Rory McIlroy has been left scratching his head as to how the American makes his new physique work.
“I don’t know what to say. That’s just the complete opposite of what you think a US Open champion does,” said McIlroy.

“Look, he’s found a way to do it. Whether that’s good or bad for the game, I don’t know, but it’s not the way I saw this golf course being played or this tournament being played.
“It’s kind of hard to really wrap my head around it.
“I don’t like talking about the distance debate because I think golf is perfect the way it is, and I think it’s a great game, and I think the best…
