Weight Watchers, Jenny Craig and other diet groups say they are supporting New York City's proposed crackdown on super sized, sugary drinks.
The anti-obesity measure calls for restaurants, movie theaters, sports arenas, food carts and delis to stop selling sodas and other sugary drinks in servings larger than 16 ounces.
Mayor Michael Bloomberg says the measure helps fight obesity in a city that spends billions of dollars a year on weight-related health problems.
Opponents say the city is overstepping its authority and infringing on personal freedom.
The proposal is set to go to a Sept. 13 vote at the city Board of Health.
