Golfer John Daly showed the world what it felt like being 100 pounds lighter after a successful gastric bypass surgery.

Rumors of a new book on this transformation are swirling after a press conference before the start of the Australian PGA where Daly is practicing.

Daly has lost over 100 pounds and appears to have cleaned up his act after years of alcohol abuse and weight gain.

Daly is known primarily for his “zero to hero” victory in the 1991 PGA Championship, his driving distance off the tee (earning him the nickname “Long John”), his non-country club appearance and attitude, and his rough-and-tumble personal life. Daly remains one of the most popular and intriguing figures on the Tour, despite his recent lack of success.
