While dieters are accustomed to exercises of will, a new English translation of Germany’s most popular diet book takes the concept to a new philosophical level. The Nietzschean diet, which commands its adherents to eat superhuman amounts of whatever they most fear, is developing a strong following in America.

Fat Is Dead, proclaims the ambitious title of the dense, aphoristic nutrition plan, which was written by Friedrich Nietzsche in the late 1880s and unearthed three years ago. After reaching bestseller lists in Europe, the book was translated into English by R.J. Hollingdale and published by Avon last month.

“One must strive to eat dangerously as one comes into the Will to Power Oneself Thin,” Nietzsche wrote. “What do you fear? By this are you truly Fattened. You must embrace your Fears, as well as your Fat, and learn to Laugh as you consume them, along with Generous Portions of Simple Salad. Remember, as you stare into the lettuce, the lettuce stares also into you.”
