Hong Kong experts warn against fad diets for weight loss

[WORLD] A survey conducted by the Hong Kong Nutrition Association reveals that many individuals adopting restrictive diets may be unaware of the associated risks, including nutrient deficiencies, metabolic imbalances, and reduced energy levels. Experts warn that while some may see rapid weight loss in the short term, the long-term health consequences remain insufficiently explored, especially for vulnerable groups such as adolescents or those with chronic health conditions.

Low-carbohydrate diets, like keto and Atkins, drastically limit carbohydrate intake in favor of proteins and fats. While these diets may result in quick weight loss, nutritionists caution that they may not be appropriate for everyone. People with diabetes or heart-related conditions are advised to consult healthcare professionals before making significant dietary changes, as these diets can impact blood sugar and cholesterol levels.

The association also pointed out that many people tend to rely on advice from friends or influencers rather than consulting certified professionals.

Recent research suggests that restrictive diets often lead to yo-yo dieting, where individuals regain lost weight—and sometimes more—once they revert to their usual eating habits. This cycle can adversely affect both physical and mental health, potentially contributing to disordered eating patterns and lower self-esteem.

In response, the association encourages a more balanced and sustainable approach, such as mindful eating and portion control, which emphasize long-term lifestyle changes over quick fixes. Registered dietitians in Hong Kong are increasingly advocating for personalized nutrition plans that account for individual health needs, activity levels, and cultural preferences.

Public health campaigns are being urged to combat misinformation on social media, where fad diets often gain popularity despite lacking scientific evidence. The Hong Kong government has been urged to work with nutrition experts to provide accessible, evidence-based resources for citizens seeking trustworthy weight management advice.

The Post's analysis of the survey results underscores the need for professional guidance when making dietary adjustments. Nutritionists recommend incorporating whole foods, regular physical activity, and behavioral changes for healthier, more sustainable outcomes.
