International Physical Activity Questionnaire (IPAQ-C) |
9 items among four domains on the health-related physical activity. A summary score of metabolic equivalent task/min per week and a categorical score of physical activity (low, moderate and high) will be used to determine the physical activity level of the participants. Physical activity are categories three level: low, moderate and high |
baseline and 12th week |

Other |
self-administer questionnaire |
process evaluation with open-ended questions to identify the acceptability, perceived barriers and experience of low GI diet from participants' perspective |

Primary |
Body mass index (BMI) |
within- and between-participant changes in BMI, BMI is defined as the body mass divided by the square of the body height, and is expressed in units of kg/m^2, resulting from body mass in kilograms(kg) and body height in metres(m).The body mass and body height will be assessed using an electronic scale and a wall-mounted stadiometer, respectively. |
baseline and 12th week |
|
Secondary |
waist circumference |
within- and between-participant changes in waist circumference. Waist circumference will be measured by using the midway point between the top of the hip bone and base of the ribs as a landmark in centimeters(cm) on bare skin at the end of a normal expiration, with arms relaxed at the sides |
baseline and 12th week |
|
Secondary |
body fat |
within- and between-participant changes in body fat. Body fat percentage (%) and different body compositions (visceral fat, subcutaneous whole body, subcutaneous trunk, subcutaneous arms, subcutaneous legs) will be assessed by body composition analyser based on the principles of bioelectrical impedance |
baseline and 12th week |
|
Secondary |
blood pressure |
within- and between-participant changes in blood pressure. Blood pressure is measured in terms of the systolic pressure over diastolic pressure and is measured in millimeters of mercury (mmHg) |
baseline and 12th week |
|
Secondary |
fasting plasma glucose |
within- and between-participant changes in fasting plasma glucose. Fasting plasma glucose will be drawn by venipuncture after an eight-hour overnight. fast for laboratory testing. Fasting plasma glucose is measured in millimoles per liter (mmol/L) |
baseline and 12th week |
|
Secondary |
Hemoglobin A1c (HbA1c) |
within- and between-participant changes in HbA1c. HbA1c will be drawn by venipuncture after an eight-hour overnight fast for laboratory testing. HbA1c will be measured in percentage (%) |
baseline and 12th week |
|
Secondary |
Total cholesterol (TC) |
within- and between-participant changes in Total cholesterol (TC). It will be drawn by venipuncture after an eight-hour overnight fast. It will be measured in millimoles per liter (mmol/L) |
baseline and 12th week |
|
Secondary |
HDL-cholesterol (HDL-C) |
within- and between-participant changes in HDL-cholesterol (HDL-C). It will be drawn by venipuncture after an eight-hour overnight fast. It will be measured in millimoles per liter (mmol/L) |
baseline and 12th week |
|
Secondary |
LDL-cholesterol (LDL-C) |
within- and between-participant changes in LDL-cholesterol (LDL-C) level. It will be drawn by venipuncture after an eight-hour overnight fast. It will be measured in millimoles per liter (mmol/L) |
baseline and 12th week |
|
Secondary |
Triglycerides level (TG) |
within- and between-participant changes in triglycerides level (TG). It will be drawn by venipuncture after an eight-hour overnight fast. It will be measure in millimoles per liter (mmol/L) |
baseline and 12th week |
|
Secondary |
dietary glycemic index (GI) value |
within- and between-participant changes in dietary GI value. The dietary GI value for each participant will be calculated by summing the products of the percentage contribution of each individual food to daily available carbohydrate intake multiplied by the food's GI value. |
baseline and 12th week |
|
Secondary |
dietary glycemic load |
within- and between-participant changes in dietary glycemic load. The dietary GL will be calculated by multiplying the dietary GI by the total amount of daily available carbohydrate intake. Dietary will be measured as g per 1000 kcal |
baseline and 12th week |

calories |
within- and between-participant changes in calories [kcal] intake |

proteins |
within- and between-participant changes in proteins[g] intake |

fiber |
within- and between-participant changes in fiber[g] intake |
baseline and 12th week |
|
Secondary |
the sense of fullness as dietary satiety |
within- and between-participant changes in the sense of fullness as dietary satiety. The sense of satiety with diet will be assessed by a visual analogue scale (VAS) consisting of a 100mm long line with the left anchor representing "very hungry" and the right anchor representing "very full." The satiety premeal, postmeal and 2 hours postmeal will be measured. |
