Michelle Obama on Obesity: Good Diet vs. Fad Diet

Though the president of the United States is arguably the most powerful man in the world, his wife wields considerable influence. Each First Lady usually has a pet social cause they wish to champion. Nancy Reagan famously tackled America's drug problem, for example, and Michele Obama recently launched a campaign to reduce childhood obesity.

It's a serious and growing problem. Childhood obesity has more than tripled in the past 30 years, according to the U.S. Centers for Disease Control and Prevention. Obesity among children aged 6 to 11 years increased from 6.5 percent in 1980 to 19.6 percent in 2008.
