In the glucomannan noodle (GMN) diet, the participants received two servings (400 g) of GMN every day to replace their daily carbohydrate intake for 4 weeks, with each serving of glucomannan noodles weighing up to 200 g with 2 g of glucomannan.

In the placebo noodle (PN) diet, the participants received the participants received the same amount of noodles without glucomannan.

Dr. Sing-Chung Li

The 100 g GMN noodle contains 1 g of konjac glucomannan powder. Participants approximately consumed 2 g GMN per day in 200 g of noodle. The intervention period was 4 weeks long. Meanwhile, the participants remained their usual eating habits except consuming any probiotics or prebiotics.

Isocaloric noodle with no konjac glucomannan powder in placebo comparator. The PN-participants daily consumed placebo noodle without any added GMN (approximately 200 g noodle per day). The intervention period was 4 weeks long. Meanwhile, the participants will remain their usual eating habits except consuming any probiotics or prebiotics.

Satiety Study of a Carbohydrate Meal to a Highly Viscous Gel Meal

Comparing the Satiety Scores of a Carbohydrate Meal to a Meal of Equal Volume in Which Half of the Volume is Replaced With a Highly Viscous Gel.

Objective satiety will be measured through subsequent food intake.
At each visit, participants will consume a pre-weighed snack (wafer cookies) that will be administered ad libitum at 90mins after consumption of the test meal. Subsequent food intake will be calculated by weighing the amount of the snack food left after consumption.

At each visit, participants will record their subjective satiety ratings using a 100 mm visual analogue scale and these rating will be combined into a total subjective appetite score using the formula (Q1+Q2+(100-Q3)+Q4)/4.
