Keith Seigner, lead restaurant analyst at Credit Suisse Grou

UNITED STATES - APRIL 15: Keith Seigner, lead restaurant analyst at Credit Suisse Group, poses with a McDonald's french fry container filled with fruit available from the fast food restaurant in New York, U.S., on Tuesday, April 15, 2008. For one month, Siegner will get all his meals from McDonald's, Wendy's and other fast-food restaurants blamed for fattening America. Siegner wants to show that people can keep fit eating at chains thought to be expanding the country's waistlines. A year into his job, he's also betting the venture will boost his reputation and give him an edge in picking stocks. (Photo by Jb Reed/Bloomberg via Getty Images)
