Rely on science, not fads, for weight loss
The global surge in the number of people who are overweight or obese has rightly focused attention on the need to adopt a healthy lifestyle.
But at a time when we are increasingly bombarded with advice on what to eat and drink, many turn to fad diets in a bid to lose weight or gain other claimed health benefits.
A study conducted by the Hong Kong Nutrition Association in recent months suggests a surprisingly high proportion – about 40 per cent – of Hong Kong people have tried such diets.
More than half of those that did opted for intermittent fasting, which involves skipping meals, and 43 per cent adopted a low-carbohydrate diet.
Their motivations were primarily a desire to lose weight or to be healthier. But the association has warned, with good reason, that such diets are often not backed by sufficient scientific evidence and can be counterproductive, leading to other health problems.
It is worrying that more than half of the respondents had used unverified information on social media. More than 40 per cent sought advice from friends or relatives.

Hong Kong water safety scandal: what happened and how to protect yourself
Hong Kong's leader has rolled out 10 measures to address a freshwater contamination case involving banned substances dirtying the supply at two public housing estates. Advertisement The Post unpacks the water safety concerns behind the saga and how people can protect themselves. 1. What's the scandal about? Residents at two public rental and subsidised estates in Fanling first reported the presence of black particles in their drinking water on Friday last week, prompting some to buy bottled water as speculation mounted over the source of the mysterious dark specks. Government test results on Thursday confirmed that the particles found in the freshwater supply at Queens Hill Estate and Shan Lai Court in Fanling were bitumen, a substance produced through the distillation of crude oil and known for its waterproofing and adhesive properties. It has been banned from use in water pipes since 2005, but authorities have stressed that the water remains safe to consume.

Replacement work on water pipe that gave Hongkongers scare to begin this year
Hong Kong will begin replacing a 400-metre (437 yards) section of water pipe lined with bitumen this year before carrying out citywide work, as it is believed to be the source of black particles dirtying the water at two public housing estates. Advertisement Secretary for Development Bernadette Linn Hon-ho said on Saturday that the government would prioritise the stretch of pipe between Queens Hill Estate and Shan Lai Court in Fanling, the only one lined with bitumen that connects the two sites. She said the city had about 700km (435 miles) of pipes lined with the substance and her bureau had told the Water Supplies Department to submit a plan to replace old ones across the city. 'To allay public concerns, particularly because of the emergence of sediment at this site, we plan to start the replacement project within this year,' Linn said. 'We have asked the Water Supplies Department to submit a plan to replace old water pipes to the Development Bureau.' Advertisement The substance has been banned from use in water pipes in the city since 2005, but authorities have stressed that the water remains safe to consume after residents voiced worries over the presence of the black particles. Linn said that bitumen-lined pipes were used internationally and posed no harm, with authorities also installing more than 1,000 filters in the water supply system.
