New York â€"  No more super-sized Cokes. Forget about stomach-busting 64-ounce sodas at KFC. Even 20-ounce Snapples are on Mayor Bloomberg's latest heath-conscious hit list.

New York City plans to ban the sale of large sodas and other sugary drinks in an effort to combat obesity.

The proposed first-in-the-nation ban would impose a 16-ounce limit on the size of sweetened drinks sold at restaurants, movie theaters, sports venues and street carts. It would apply to bottled drinks as well as fountain sodas.

The ban, which could take effect as soon as March, wouldn't apply to diet sodas, fruit juices, dairy-based drinks or alcoholic beverages.

Mayor Michael Bloomberg said Wednesday that he "thinks it's what the public wants the mayor to do."

But there's speculation that customers will just buy two 16-ounce bottles instead of one 20-ounce drink.

A spokesman for the New York City Beverage Association, Stefan Friedman, criticized the proposal as "zealous." He said officials should seek solutions that are actually going to curb obesity.

The proposal requires the approval of the city's Board of Health.
