America is big. Too big. Overweight and sedentary. But not for long, perhaps, thanks to Antronette Yancey, UCLA professor of health services in the School of Public Health. A basketball player, former European model, poet and spoken word artist, Yancey takes on TV ads, fast food and other fat-building antagonists in a tireless effort to get America fit. She admits she was once described as someone who could "talk a hungry dog off a meat wagon." At UCLA, she co-founded the Center to Eliminate Health Disparities because "we're not just interested in what's happening and why - we intend to change it."
