Among the many things Los Angeles is known for, keeping trim might be at the top of the list. You can even see it in the city’s recent politics.

A city council member in Los Angeles is trying to stop new fast-food restaurants from opening in a 32-square-mile part of L.A. where obesity rates are high. The Wall Street Journal reports the targeted area is already home to some 400 fast-food restaurants. Thirty percent of adults in the area are obese, compared with about 21 percent in the rest of the city. Today, a committee will weigh in on the proposed ordinance before sending it on to the full city council for a vote.

Not that this will necessarily affect the area’s obesity rate, but the L.A. Times took a look at what makes people fat and has a list of links with different popular theories. My favorite: Maybe it’s all that high-fructose corn syrup. Is that stuff good for anything?
