Korea has the lowest obesity rate among members of the Organization for Economic Cooperation and Development.

The Strategy and Finance Ministry said Sunday that the national obesity rate was three-and-a-half percent. The finding came after the OECD released results of a three-year survey on obese and overweight people aged 15 or above living in the organization's 30 member states.

Japan had the second-lowest obesity rate of three-point-nine percent, followed by Switzerland and Norway, but the survey said Korea had more overweight people than Japan.

The United States had the highest obesity rate with 34-point-three percent followed by Mexico, New Zealand and Britain.
