The number of diabetes diagnosis also jumped 17 percent in New York, while the rate in the rest of the country stayed the same.
Health officials say a big reason for the gain is sugary sodas and sweetened drinks, which add a lot of calories.
According to the study, some 173,500 adult New Yorkers became obese and more than 73,000 were newly diagnosed with diabetes in that time period.
"Obesity, and with it diabetes, are the only widespread major health conditions that are getting worse in New York City," health commissioner Dr. Thomas Frieden said. "To tackle this problem and help prevent the devastating effects of these conditions, New Yorkers must to take in fewer calories, and to help them do that we must change our environment."
