The Effects of Low Glycemic Index (GI) Diet on Cardiometabolic Outcomes

Status Completed

Clinical Trial Summary

The aim of this study is to investigate the effects and the acceptability of low GI diet versus a conventional healthy diet on the BMI and other cardiometabolic risk factors of obese Chinese adults in Hong Kong.

Clinical Trial Description

29.9% of persons aged 15-84 in Hong Kong are obese. Obesity poses significant detrimental consequences for one's health. Obese patients have an increased risk of mortality when compared with people with normal BMI. Obesity results in arterial hypertension, hyperlipidaemia, heart disease and type 2 diabetes. Low GI diets have been investigated for their impact on weight control. Evidence showed that low GI diets were effective in lowering body mass index. However, the evidence was usually generated from Western populations, thus excluding the influence of Chinese culture on diet.The aim of this study is to investigate the effects and the acceptability of low GI diet versus a conventional healthy diet on the BMI and other cardiometabolic risk factors of obese Chinese adults in Hong Kong. A prospective, two-arm randomized-controlled trial will be conducted to examine the effect of a low GI diet education program on cardiometabolic outcomes in Chinese adults with obesity. The intervention group will receive a low GI diet education, including a one-off, 60-minute, face-to-face, educational session conducted by the research nurse for GI knowledge input. An informational booklet will be given out during the education session.Three follow-up telephone calls of fifteen minutes will be conducted by the research nurse at the 2nd, 5th , and 8th weeks after completing the face-to-face education session. While the control group will receive an education pamphlets on obesity and balanced diet.Three follow-up telephone calls of fifteen minutes will be conducted by the research nurse at the 2nd, 5th , and 8th weeks after receiving the pamphlets. At baseline, demographic and clinical data, including BMI, waist circumference, body fat, blood pressure, fasting plasma glucose, HbA1c, lipid profile, 3-day food diary, International Physical Activity Questionnaire (IPAQ-C), and the sense of fullness will be collected. On the 12th week, data about the BMI, waist circumference, body fat, blood pressure, fasting plasma glucose, HbA1c, lipid profile, 3-day food diary, IPAQ-C, and the sense of fullness and a questionnaire on the evaluation process will be collected. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
