"My personality was being swallowed by the fat just like the rest of me," says Lindsey Friedberg, a 23-year-old graduate student at the Academy of Art University in San Francisco. Friedberg, who grew up in Ocean City, New Jersey, surrounded by "slender and tan" girls, has battled her weight all her life. In high school she tried counting calories, eating raw food, drinking 12 bottles of water a day and writing down everything she ate, including the gum she chewed and number of mints. But nothing worked.
