After months of legal disputes, New York City in May began enforcing a law aimed at curbing obesity by requiring certain restaurants to post the calorie content of each menu item. It was a transparently snobby law: only chain outlets were affected. Philadelphia followed suit in November. But the Los Angeles City Council went several steps further in the war on fat. It banned any new fast-food restaurant from opening in certain L.A. neighborhoods for a full year. The council apparently felt that residents of those neighborhoods residents who are disproportionately African-American and Latino cannot decide for themselves what to consume.
