The Consumer Council is sensing not-so-good vibrations from machines manufacturers claim can help with weight loss.
The council investigated the claims of makers of seven vibration plates promoted as home-use exercise machines and found there was not enough evidence to “support the use of the machines alone to reduce body fat and body weight”.
The results showed that the plates, which sell for between HK$2,700 (US$348) and HK$5,000 each, could only increase muscle activity by a small margin.
An hour of non-stop vibrations only trimmed 10 grams of body fat, compared with the 34 grams that could be shed during an hour of housework, Ming Pao Daily reported Tuesday.
Consumer authorities in Taiwan have ruled that the claims made for the products, which are still on sale in Hong Kong, are false.
According to Professor Stanley Hui Sai-chuen of Chinese University’s sports science department, many other everyday activities would be much more effective than using vibration plates. An hourlong brisk walk, for example, can burn off 43 grams of fat, he said.
The council said the manufacturers might have violated the Trade Descriptions Ordinance and it had passed on the information to the Customs and Excise Department.
Late last month, Taiwan-based Johnson Health Tech was fined NT$100,000 (US$3,330) over claims that one of its machines could burn off 120 Kcal within 10 minutes of use, the report said.
