More Taiwanese are gaining weight while others are more quickly becoming underweight, as the weight spectrum shows an increasing gap between the heaviest and lightest people, with teenagers and elderly people being more underweight than average, a nutrition and health survey showed.
The survey, conducted from 2017 to 2020 by the Health Promotion Administration (HPA), was published in May this year.
The proportion of obese people increased in all age groups, with 50.7 percent over the age of 19 being overweight or obese, defined as those with a body mass index (BMI) greater than 24, a 6 percent increase from surveys conducted from 2013 to 2016, it showed.

About half of Taiwanese over the age of 45 are overweight or obese; 60 percent of people aged 65 to 70 are in that category; and 30 percent under 18 are above normal weight, it showed.
Many people who sought weight loss treatments said that they gained weight during the COVID-19 pandemic, Taipei Medical University’s Weight Management Center director Wang Wei (王偉) said.
The proportion of underweight people — with a BMI below 18.5 — under 18 or older than 65 also increased, the survey showed.
Underweight people comprise 10.1 percent of children aged seven to 12; 6.6 percent of teenagers aged 13 to 15; 12.6 percent of teenagers aged 16 to 18; and 2.8 percent of people aged 65 to 74, all higher from the previous survey, it showed.
Teenagers being underweight is related to their diets, exercise and sleep, the HPA said.
More than 80 percent of teenagers eat out more than seven times per week, while about 50 percent do not get enough daily physical activity and some sleep less than seven hours on weeknights, it said.
Finicky eating habits are the primary cause of children and teenagers being underweight, said Lo Yu-fang (羅玉芳), a physician at Cheng Hsin General Hospital’s department of pediatrics.
Some children lack clear concepts of a healthy diet or mistakenly believe that it is fine not to eat when not hungry, she said, adding that some even cut their food expenditures to buy games or participate in hobbies.
The body shapes of celebrities might also contribute to children and teenagers being underweight, said Kuo Tien-ling (郭恬伶), a physician at Shin Kong Memorial Wu Ho-Su Hospital’s department of pediatrics.
About 70 percent of people aged 65 or older have missing teeth, and 63 percent have dietary restrictions, contributing to their weight issues, HPA Community Health Division head Lo Shu-ying (羅素英) said.

UNREASONABLE SURVEILLANCE: A camera targeted on an road by a neighbor captured a man’s habitual unsignaled turn into home, netting him dozens of tickets The Taichung High Administrative Court has canceled all 45 tickets given to a man for failing to use a turn signal while driving, as it considered long-term surveillance of his privacy more problematic than the traffic violations. The man, surnamed Tseng (曾), lives in Changhua County and was reported 45 times within a month for failing to signal while driving when he turned into the alley where his residence is. The reports were filed by his neighbor, who set up security cameras that constantly monitored not only the alley but also the door and yard of Tseng’s house. The surveillance occurred from July
A Japan Self-Defense Forces vessel entered the Taiwan Strait yesterday, Japanese media reported. After passing through the Taiwan Strait, the Ikazuchi was to proceed to the South China Sea to take part in a joint military exercise with the US and the Philippines, the reports said. Japan Self-Defense Force vessels were first reported to have passed through the strait in September, 2024, with two further transits taking place in February and June last year, the Asahi Shimbun reported. Yesterday’s transit also marked the first time since Japanese Prime Minister Sanae Takaichi took office that a Japanese warship has been sent through the Taiwan
‘SAME OLD TRICK’: Even if Beijing resumes individual travel to Taiwan, it would only benefit Chinese tourism companies, the Economic Democracy Union convener said China’s 10 new “incentives” are “sugar-coated poison,” an official said yesterday, adding that Taiwanese businesses see them clearly for what they are, but that Beijing would inevitably find some local collaborators to try to drums up support. The official, speaking on condition of anonymity, made the remark ahead of a news conference the General Chamber of Commerce is to hold today. The event, titled “Industry Perspectives on China’s Recent Pro-Taiwan Policies,” is expected to include representatives from industry associations — such as those in travel, hotels, food and agriculture — to request the government cooperate with China’s new measures, people familiar with
