Abstrakt:	Aims: An assessor-blinded randomized controlled trial was conducted to assess the effect of a culturally tailored low-glycaemic index (GI) dietary educational intervention on body mass index and cardiometabolic risks for Chinese people with obesity in Hong Kong. Methods and Results: A total of 166 Chinese adults in Hong Kong with obesity were randomized to the intervention group (n = 83) or the control group (n = 83). The intervention group received the culturally sensitive low-GI dietary educational intervention based on the health belief model, consisting of an educational booklet, one individual interactive educational session, and three follow-up telephone calls. The control group received general advice on a healthy diet, including a pamphlet, one individual education session, and three follow-up telephone calls. Outcome measures included body mass index, cardiometabolic risk factors, dietary intake variables, and sense of satiety. Data collection was conducted at baseline and post-intervention at 12 weeks. A generalized estimating equation model was used to compare the difference in changes in outcome variables between groups. Compared with the control group, the intervention group exhibited a significant reduction in dietary glycaemic load (β = -6.963, P = 0.026) at post-intervention. No significant effects were found on other outcomes. Conclusion: A 12-week culturally tailored and health belief model-based low-GI dietary educational intervention significantly reduced the dietary glycaemic load and showed the feasibility of the low-GI dietary intervention in Chinese adults in Hong Kong with obesity. A longer intervention period and follow-up might be required to achieve improvements in reducing cardiometabolic risk factors in people with obesity. Registration: ClinicalTrials.gov: NCT04152213.
