Vincent Anselmo Gironda (November 9, 1917 – October 18, 1997)[1] was an American professional bodybuilder, personal trainer, author, co-founder of the supplement company NSP Nutrition, and owner of the celebrity-frequented Vince's Gym.

While he was still a young child, the family moved out west to Los Angeles when his father, a stuntman, was offered work in the upcoming Ben Hur film.

Vince tried his hand at being a stuntman as well but when he saw a photograph of John Grimek, he realized he needed more physical development and began lifting weights at the age of 22.

[4] He ate butter, cream, eggs, milk and red meat in high quantities and only a small amount of carbohydrates.

[4] In certain circumstances, Gironda would recommend up to three dozen fertile hen-eggs a day, along with raw (unhomogenized, unpasteurized) cream or half-and-half milk.

Large amounts of fertile eggs, he said, are equal to the anabolic steroid Dianabol in effectiveness.

The release of the book prompted a promotion tour where the Iron Guru gave sold-out seminars throughout the US and Canada.
