The objective of this study is to compare the effectiveness of a low-GI diet program and a standard counseling program in the treatment of obese Thai children.
Obese children aged 9-16 years from King Chulalongkorn Memorial Hospital were randomized to receive instruction either for a low-GI diet (intervention group) or a low-calorie, low-fat diet (control group). Both groups were followed-up every month for six months. The primary outcomes were body composition changes during the six-month period, measured by dual X-ray absorptiometry (DEXA) and bioelectrical impedance analysis (BIA). Secondary outcomes were metabolic syndrome risk changes measured by fasting plasma glucose, insulin, and lipid profiles.
The adherence to the nutritional education and physical activity recommendation was evaluated by using three-day dietary records (two weekdays and one weekend day) and a physical activity questionnaire at each visit. All participants were examined and counseled about physical activity and life style modification strategies by a pediatrician at every visit.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| low calorie/fat diet | Active Comparator | The low calorie/fat diet group, obese children aged 9-16, received conventional behavioural lifestyle modification instructions x 1/month for 6 months about low-calorie (approximately 1200-1300 kcal/day), low-fat (25% of total calories from fat) and about physical activity (increase non-weight bearing exercise 30 minutes/day at least x 3 times/week, increase physical activity in their routine and decrease sedentary activity). |
|
| Low glycaemic index diet | Experimental | Low glycaemic index diet group, obese children of both sexes aged 9-16, received experimental behavioural lifestyle modification instructions x 1/month for 6 months about low glycaemic index diet (selection of low-GI carbohydrates with the caloric distribution of carbohydrate 50-55%: protein 15-20%: fat 30-35%, instruction by two-hour small classes with parental participation low GI cooking demonstration and food labeling guidance) and about physical activity (increase non-weight bearing exercise 30 minutes/day at least x 3/week, increase physical activity in their routine and decrease sedentary activity). |
