Ask what Korea is talking about.

New analysis from the Korea Disease Control and Prevention Agency (KDCA) shows that half of South Korean men in their 30s and 40s are obese, with the adult obesity rate rising to 35.4% last year from 27.9% a decade ago, Yonhap reports. The KDCA's in-depth analysis of the 2025 Community Health Survey, covering about 230,000 adults, found that obesity rates for men in their 30s and 40s each exceed 50%, according to Maeil Business Newspaper. Regional disparities are stark: Ulsan and South Jeolla Province have the highest obesity rates, while Gangwon's Cheorwon County tops the list among districts, Chosun Ilbo reports. Kyunghyang Shinmun adds that areas with higher obesity rates have monthly household incomes over 3 million won lower than those with lower rates.
