Viet Nam still has one of the world's lowest obesity rates, but overweight cases are rising fast, per the National Institute of Nutrition.
Adult obesity grew from 2.6% in 2010 to 6.6% in 2020, while child obesity rose from 8.5% to 19%. Teens overweight now top 50% in Ho Chi Minh City and 41% in Ha Noi.
Experts say shifting diets are testing Viet Nam's "naturally thin" reputation.
