Penn Jillette's New York Times bestselling account of his "extremely funny and somewhat profane journey to discovering a healthy lifestyle...that will motivate others to seek weight-loss solutions" (The Washington Post). More than three hundred and thirty pounds and saddled with a systolic blood pressure reading at dangerous heights, legendary magician Penn Jillette found himself at a crossroads. He needed a drastic lifestyle change if wanted to see his small children grow up. Enter Crazy Ray. A former NASA scientist and unconventional, passionate innovator, Ray Cronise changed Penn Jillette's life with his wild "potato diet." In Presto, Jillette takes us along on his journey from skepticism to the inspiring, life-changing momentum that transformed the magician's body and mind. He describes the process in hilarious detail, as he performs his Las Vegas show, takes meetings with Hollywood executives, hangs out with his celebrity friends and fellow eccentric performers, all while remaining a dedicated husband and father. Throughout, he weaves in his views on sex, religion, and pop culture, making his story a refreshing, genre-busting account. Outspoken, frank, and bitingly clever, Presto is an incisive, rollicking read. In the end, it is "undeniably inspiring" (Booklist).
