TV says it. Magazines say it. American society commands it. You must be thin. You must be young. Fad diets. Fat-purging pills. Fitness clubs. Liposuction. Breast implants. Steroids.

In the tomorrow of Thinner Than Thou, the cult of the body has become the one true religion. The Dedicated Sisters are a religious order sworn to help anorexic, bulimic, and morbidly obese youth. Throughout the land, houses of worship have been replaced by the health clubs of the Crossed Triceps. And through hypnotically powerful evangelical infomercials, the Reverend Earl preaches the heaven of the Afterfat, where you will look like a Greek god and eat anything you want. Just sign over your life savings and come to Sylphania, the most luxurious weight-loss spa in the world, where the Reverend himself will personally supervise your attainment of physical perfection.

But the glory of youth and thinness that America worships conceals a hidden world where teens train for the competitive eating circuit, where fat porn and obese strippers feed people's dark desires, and where an underground railroad of rebellious religions remember when people worshipped God instead of the Afterfat.

As Annie, an anorexic, and her friend Kelly, who is so massive she can barely walk, find out, the tender promises of the Dedicated Sisters are fulfilled by forced feedings and enforced starvation in hidden prisons.

As middle-aged Jeremy discovers, Sylphania is a concentration camp where failure to lose weight and tone up leads to brutal punishment.
The Rev. Earl's public sympathy for the overweight conceals a private contempt . . . and, beneath that, a terrible longing known only to a select few.

The inevitable decay of old age is the only thing keeping mankind from reaching perfection. Luckily, Reverend Earl has a plan that will take care of that . . . .
